Description

Clamping-adjustable automobile annular part mounting platform and mounting method

Technical Field

The invention relates to the technical field of automobile part machining, in particular to a clamping adjustable automobile annular part mounting platform and a clamping adjustable automobile annular part mounting method.

Background

After the automobile annular part is machined into a blank, metal machining treatment such as spraying, polishing and the like is required, and testing treatment such as roundness testing and the like can be carried out. In addition, the above-described treatment is industrially required to be carried out in a state where the ring-shaped component is held.

Because the annular part has an inner ring (namely an inner wall) and an outer ring (namely an outer wall), the prior art is divided into two modes of inner support clamping (namely inner ring clamping) and outer pressure clamping (namely outer ring clamping) according to the mode of clamping the annular part. Internal stay centre gripping is like the clamping device for automobile annular part that patent application 201911289169.2 disclosed, this type of technical scheme be through with the polylith grip block with the outside different positions of moving to its inner wall of annular part of different directions, polylith grip block combined action realizes annular part's centre gripping. External pressure centre gripping is like the annular metal parts burr-grinding machine that patent application 201510515653.8 disclosed, this type of technical scheme be through inwards moving the different positions of its outer wall of annular part with different directions with polylith grip block, and polylith grip block combined action realizes the centre gripping of annular part.

However, the two prior art methods adopt internal support clamping and external pressure clamping, and have the following technical defects: when the outer wall or the inner wall of the ring-shaped part is clamped, only the opposite surfaces (the opposite surface when the clamping surface is the outer wall is the inner wall, and the opposite surface when the clamping surface is the inner wall is the outer wall) are completely exposed, and the clamping surface is difficult to carry out post-treatment including gold processing due to the existence of the clamped area. Therefore, in the prior art, taking the example of first clamping the driven member and then clamping the driven member, the inner wall of the annular part is clamped, the opposite surface (i.e., the outer wall) is processed, then the part is taken out, the outer wall of the annular part is clamped, and then the inner wall is processed. Therefore, at present, when the inner wall and the outer wall of the annular part of the automobile are industrially processed, the process is interrupted, the continuity of the online processing of the inner wall and the outer wall of the annular part of the automobile is difficult to realize, and the industrial processing efficiency is low.

The invention has the advantages that:

firstly, when the automobile annular part is clamped and installed by adopting the clamping adjustable automobile annular part installation platform, only inner ring clamping, inner ring clamping and outer ring clamping and only outer ring clamping are realized in sequence in the single extension motion process of the telescopic end of the telescopic device, and the simultaneous inner ring clamping and outer ring clamping are utilized as intermediate links for connecting only the inner ring clamping and the outer ring clamping, so that the staggered realization of the inner wall clamping and the outer wall clamping of the automobile annular part is realized on the premise of no process interruption, the continuity of industrial processing is improved, and the processing efficiency is improved;

secondly, the extension movement of the telescopic end of the telescopic device can realize feeding, and by matching with the clamping action, the feeding of the automobile annular part only with inner ring clamping is realized, the continuous clamping process is switched to the outer ring clamping, the release of the automobile annular part can be realized in the contraction resetting process of the telescopic end, the blanking is further facilitated, and the sequential realization of the feeding, the clamping and the blanking is realized;

thirdly, because the inner ring clamp and the outer ring clamp are positioned at different positions, when the inner wall and the outer wall of the automobile annular part are respectively subjected to post-treatment such as spraying, polishing or diameter measurement, the post-treatment device corresponding to the inner wall of the automobile annular part and the post-treatment device corresponding to the outer wall of the automobile annular part can be arranged in a staggered manner in space (namely, arranged in a staggered manner from front to back), so that the phenomenon that the devices are crowded and interfere with each other due to the concentrated arrangement of two groups of post-treatment devices is prevented;

fourthly, when the mounting platform is used for clamping, the front side surface and the rear side surface of the automobile annular part can be always exposed to the outside, and the processing on the front side surface and the rear side surface of the automobile annular part is not influenced;

fifthly, the clamping ends of the plurality of inner supporting clamping blocks are expanded outwards to form expanding openings, so that inner supporting force is applied to different positions, namely a plurality of angle directions, of the inner wall of the automobile annular part, and stable and firm clamping force is achieved when the inner ring is clamped; in a similar way, the clamping ends of the external pressure clamping rods are folded inwards to form a necking, so that external pressure is applied to different positions, namely a plurality of angle directions, of the outer wall of the automobile annular part, and stable and firm clamping force is achieved when the outer ring is clamped;

sixthly, because the inner supporting clamping block and the outer pressure clamping rod are positioned at the front end of the telescopic end in industrial application, the movement state of the inner supporting clamping block and the outer pressure clamping rod is difficult to change spontaneously, and the inner supporting clamping block and the outer pressure clamping rod participate in clamping, so that the independence of the inner supporting clamping block and the outer pressure clamping rod in movement needs to be kept and is not interfered; in the process of moving back and forth, the matching state of the inner clamping driven member and the inner ring braking member is changed by utilizing the change of the mutual position between the inner clamping driven member and the inner ring braking member, and the matching state of the outer clamping driven member and the outer ring braking member is changed by utilizing the change of the mutual position between the outer clamping driven member and the outer ring braking member, and the change of the state is respectively and indirectly converted and mapped to the change of the motion states of the inner supporting clamping block and the outer pressure clamping rod, so that the accuracy, the reliability and the independence of the motion changes of the inner supporting clamping block and the outer pressure clamping rod are achieved.

In conclusion, the invention has the advantages that the staggered clamping of the inner wall and the outer wall of the annular part is realized on the premise of continuous and uninterrupted process, and the industrial processing continuity is improved.

Further, be provided with the ascending receipts silo of opening in the below of flexible end, when flexible end by preceding to the back shrink motion that resets, until each internal stay grip block inwards do draw in to break away from the back with the inner wall of automobile annular part, automobile annular part falls into down to receiving in the silo.

Furthermore, the limiting sleeve structure and the matching mode of the limiting sleeve structure and the telescopic end can provide point positions for the installation of the inner ring braking part and the outer ring braking part and ensure that the telescopic end can move back and forth while the limiting sleeve is relatively immovable; on the other hand, the telescopic end can rotate to drive the limiting sleeve to synchronously rotate.

Further, the inner ring braking part comprising the horizontal section allows the inner supporting clamping block to be a deformable clamping block, and also allows the inner supporting clamping block to be a rigid non-deformable clamping block.

Furthermore, by adopting the structure of the inclined section, the synchronous inward folding or outward extending movement of the plurality of inner supporting clamping blocks can be realized through the forward and backward rotation of the inner clamping driven piece, and a group of inner clamping driven pieces and an inner clamping driving mechanism do not need to be independently configured for each inner supporting clamping block, so that the integration effect of the device is improved.

Further, the outer clamping gear rotates for a circle to enable the outer pressure clamping rod to rotate forwards and backwards in a reciprocating mode once (namely, to swing in a reciprocating mode once), and the outer pressure clamping rod forms a rocker. The phenomenon that the outer ring clamping and the inner ring clamping do not occur along with the continuous forward extension movement of the telescopic end after the outer ring is clamped to the rear end can be realized, so that the blanking is allowed to occur in the forward extension stage of the telescopic end instead of the backward contraction stage of the telescopic end. And then realize flexible end single extension motion, realize only having inner ring centre gripping (material loading), having inner ring centre gripping and outer ring centre gripping simultaneously, only having outer ring centre gripping, not having inner ring centre gripping and outer ring centre gripping simultaneously (unloading) in order.

Further, the external clamping driving mechanism including the incomplete gear allows the external pressure clamping rod to be a deformable clamping rod, and also allows the external pressure clamping rod to be a rigid non-deformable clamping rod.

Furthermore, because the inner ring clamping and the outer ring clamping are positioned at different positions, when the inner wall and the outer wall of the automobile annular part are respectively subjected to post-treatment such as spraying, polishing or diameter measurement, the first grinding machine and the second grinding machine can be arranged in a staggered mode in space (namely, arranged in a staggered mode in the front-back direction), and the phenomenon that the two grinding machines are arranged in a concentrated mode to cause the device to be crowded and cause mutual interference is avoided.

Example 1

As shown in fig. 1-3, the present embodiment discloses a clamping adjustable platform for mounting an automotive annular part, which includes a mounting base 1, a telescopic device 2, an inner clamping follower 31, an inner supporting clamping block 32, an inner clamping driving mechanism 33, an outer clamping follower 41, an outer pressure clamping rod 42, an outer clamping driving mechanism 43, an inner ring brake 5, and an outer ring brake 6. The telescoping device 2 is mounted on the mounting base 1. The inner clamping follower 31, the inner clamping drive mechanism 33, the outer clamping follower 41, and the outer clamping drive mechanism 43 are all provided on the telescopic end of the telescopic device 2.

During the extension of the telescopic end of the telescopic device 2 from back to front, the inner clamping follower 31 can change from forward rotation to reverse rotation as the contact time of the inner clamping follower 31 with the inner ring stopper 5 continues. The forward rotation of the outer gripping follower 41 continues as the time for which the outer gripping follower 41 is in contact with the outer ring stopper 6 continues. And in the process of retracting and resetting the telescopic end from front to back, along with the continuous contact time of the inner clamping driven member 31 and the inner ring braking member 5, the inner clamping driven member 31 can change from forward rotation to reverse rotation. As the contact time of the outer gripping follower 41 with the outer ring stopper 6 continues, the outer gripping follower 41 continues to perform reverse rotation.

The forward rotation of the inner clamping follower 31 can drive the inner supporting clamping blocks 32 to slide outwards through the inner clamping driving mechanism 33, so that the clamping ends of the inner supporting clamping blocks 32 form outwards extending movement. The reverse rotation of the inner clamping follower 31 can drive the inner supporting clamping blocks 32 to slide inwards through the inner clamping driving mechanism 33, so that the clamping ends of the inner supporting clamping blocks 32 form inward converging motion.

The outer clamping driving mechanism 41 drives the clamping ends of the outer pressure clamping rods 42 to rotate inwards in the process that the outer clamping driven member 41 rotates forwards, and the clamping ends of the outer pressure clamping rods 42 rotate inwards to form inward furling movement; the outer clamping driving mechanism 41 drives the clamping ends of the outer pressure clamping rods 42 to rotate outwards in the process that the outer clamping follower 41 rotates reversely, and the clamping ends of the plurality of outer pressure clamping rods 42 rotate outwards to form outwards extending movement.

The inner ring clamping is formed in the process that a plurality of inner supporting clamping blocks 32 outwards extend to the clamping ends of the inner supporting clamping blocks to abut against the inner wall 101 of the annular part of the automobile. The outer ring clamp is formed in the process that the clamping ends of the plurality of outer pressure clamping rods 42 are inwardly gathered to abut against the outer wall 102 of the automobile annular part.

The telescopic end can sequentially pass through the first time, the second time and the third time in the process of extending from back to front. At the first time, there is only an inner ring grip. At a second time, there is both an inner ring grip and an outer ring grip. At a third time, there is only outer ring grip.

The operation principle of the present invention is described in terms of the inner gripping follower 31, and the movement of the outer gripping follower 41 is described in the meantime.

When the automobile annular part is installed by adopting the clamping adjustable automobile annular part installation platform, the telescopic end of the telescopic device 2 is firstly adjusted to the initial position, and the initial position is set behind the inner ring braking piece 5. Then, the telescopic end of the telescopic device 2 is extended forwards, and the inner clamping follower 31, the outer clamping follower 41, the inner supporting clamping block 32, the outer pressure clamping rod 42, the inner clamping driving mechanism 33 and the outer clamping driving mechanism 43 are synchronously driven to move forwards. The automobile annular part 10 is vertically placed in front of the telescopic device 2 in a manner of being held by a manipulator or a worker. In the process of extending movement of the telescopic end from back to front, along with the continuation of the contact time of the inner clamping driven member 31 and the inner ring braking member 5, the inner clamping driven member 31 firstly rotates in the forward direction, the inner clamping driving mechanism 33 drives each inner supporting clamping block 32 to do expanding movement (namely flaring movement) outwards, when the clamping end of each inner supporting clamping block 32 simultaneously abuts against the inner wall 101 of the automobile ring part and clamps the automobile ring part, and in the process of forward rotation of the inner clamping driven member 31, the outer clamping driven member 41 always rotates in the forward direction, the clamping end of each outer pressure clamping rod 42 gradually draws in movement (namely necking movement) inwards, the clamping end of each outer pressure clamping rod 42 is always not in contact with the outer wall 102 of the automobile ring part or the clamping end of each outer pressure clamping rod 42 draws in movement inwards until the clamping end of each outer pressure clamping rod 42 contacts with the outer wall 102 of the automobile ring part but is not enough to clamp the automobile ring part, therefore, the clamping of the inner ring is only formed, the manipulator or the hand is released, and the initial moment of the first time is reached; then, in the first time, the automobile annular part moves forward in a state that only the inner ring is clamped, the outer clamping follower 41 continuously rotates forward, and each outer pressure clamping rod 42 further gradually draws inward until the clamping end of each outer pressure clamping rod 42 simultaneously presses against the outer wall 102 of the automobile annular part and clamps the automobile annular part, so that the inner ring clamping and the outer ring clamping are simultaneously formed, and the automobile annular part enters the initial time of the second time. Then, in the second time, the automobile annular part moves forward in the states of inner ring clamping and outer ring clamping until the inner clamping follower 31 moves reversely to make each inner clamping block 32 move inward in a furling manner until the inner clamping block is separated from the inner wall 101 of the automobile annular part or make each inner clamping block 32 move inward in a furling manner until the clamping end of each inner clamping block 32 is still in contact with the inner wall 101 of the automobile annular part but is not enough to clamp the automobile annular part, and at this time, the clamping end of the outer pressure clamping rod 42 is always pressed against the outer wall 102 of the automobile annular part and clamps the automobile annular part, so that the outer ring clamping is only existed, and the initial time of the third time is reached. The third time of the present invention may be only the initial time of the third time, or may be a time period including the initial time of the third time. When the third time is a time period, in the third time, the automobile annular part moves forward to the set position in a state that only the outer ring is clamped, and the inner clamping follower 31 moves reversely until the gap between the clamping end of each inner supporting clamping block 32 and the inner wall 101 of the automobile annular part is gradually increased. Therefore, one-time extension movement of the telescopic end is completed, only inner ring clamping, simultaneous clamping of the inner ring clamping and the outer ring clamping, and only outer ring clamping of the automobile part are sequentially achieved, and one-time installation of the automobile annular part is completed.

In the process of the telescopic end shrinking and resetting from front to back, the annular part of the automobile takes the mode that only the outer ring is clamped as a starting point, and similarly, a first resetting time, a second resetting time and a third resetting time which are respectively opposite to the first time, the second time and the third time exist, and the processes are carried out according to the sequence of the third resetting time, the second resetting time and the first resetting time from first to back. When the third reset time is a time period, the inner clamping driven piece 31 moves forward until a gap between the clamping end of each inner supporting clamping block 32 and the inner wall 101 of the automobile annular part is gradually reduced, the automobile annular part moves backwards under the state that only the outer ring is clamped until the clamping end of each inner supporting clamping block 32 abuts against the inner wall 101 of the automobile annular part and clamps the automobile annular part, and the initial time of the second reset time is reached; when the third reset time is the moment, the initial moment of the second reset time is entered at the next moment of the moment; in the second reset time, the automobile annular part moves backwards in the states of inner ring clamping and outer ring clamping until the clamping ends of the outer pressure clamping rods 42 are expanded outwards to be separated from the outer wall 102 of the automobile annular part or the clamping ends of the outer pressure clamping rods 42 are furled inwards to be not enough to clamp the automobile annular part although the clamping ends of the outer pressure clamping rods 42 are still in contact with the outer wall 102 of the automobile annular part due to the reverse motion of the outer clamping follower 41, and the initial time of the first reset time is reached; during the first reset time, only inner ring clamping is present; when the outer clamping driven member 41 continuously rotates reversely, and the inner clamping driven member 31 rotates reversely until each inner supporting clamping block 32 draws inward until being separated from the inner wall 101 of the automobile annular part or each inner supporting clamping block 32 draws inward until the clamping end of each inner supporting clamping block 32 still contacts with the inner wall 101 of the automobile annular part but is not enough to clamp the automobile annular part, the release of the automobile annular part is realized, the automobile annular part is taken out, and the unloading of the automobile annular part is completed. And then the telescopic end is completely reset.

As shown in fig. 3-5, in some embodiments, the telescopic end has a cavity 211 formed therein and a guiding hole 212 formed in the surface thereof, the guiding hole 212 is communicated with the cavity 211, and the plurality of guiding holes 212 are annularly distributed around the central axis of the telescopic end. The inner clamp driving mechanism 33 includes a guide plate 331 and a transmission plate 332.

As shown in fig. 6, the guide plate 331 is fixed or detachably mounted in the cavity 211, a guide slot 3311 is formed in the guide plate 331, one end of the guide slot 3311 is close to a central axis of the guide plate 331, and the other end of the guide slot 3311 extends outward to an edge of the guide plate 331. The plurality of guide grooves 3311 are annularly distributed around the central axis of the guide plate 331, the inner supporting clamping block 32 is slidably fitted with the corresponding guide groove 3311, and the clamping end of the inner supporting clamping block 32 can extend outward from the corresponding guide hole 212.

As shown in fig. 2, 4 and 7, the transmission disc 332 is vertically disposed in the cavity 211, the transmission disc 332 is connected to one end of the transmission disc connecting shaft 3342, the transmission disc connecting shaft 3342 is rotatably fitted to the cavity 211, as shown in fig. 2 and 7, an involute guide through hole 3321 is formed in the transmission disc 332, and one end of the involute guide through hole 3321 is gradually changed from a position close to a central axis of the transmission disc 332 to a position close to an edge of the transmission disc 332 in an inclined or curved manner, so as to form the other end of the involute guide through hole 3321. A plurality of involute guide through holes 3321 are annularly distributed around the central axis of the drive disk 332. The guide grooves 3311, the inner support holding block 32, the involute guide through-holes 3321, and the guide holes 212 are equal in number and correspond to one another. The central axes of the guide disc 331, the transmission disc 332 and the telescopic end are collinear.

As shown in fig. 7, the inner support holding block 32 is connected to a top pillar 333, and the top pillar 333 is inserted into the corresponding involute guide through hole 3321. The rotation of the driving plate 332 can drive the inner support holding block 32 to slide in the guiding slot 3311. The other end of the transmission disc connecting shaft 3342 is linked with the inner clamping driven member 31 through an inner transmission component. As shown in fig. 2-4, in some embodiments, the internal drive assembly includes two bevel gears 3341 that engage with each other, one of the bevel gears 3341 being connected to the other end of the drive plate connecting shaft 3342, the other bevel gear 3341 being connected to the internal holding follower 31 via a first shaft 3343, the first shaft 3343 being rotatably engaged with the chamber body 211.

According to the invention, the first rotating shaft 3343 is driven to rotate by the rotation of the internal clamping driven part 31, and the transmission disc connecting shaft 3342 is driven to rotate by the reversing transmission of the two conical gears 3341, so that the rotation of the transmission disc 332 is realized. The transmission disc 332 rotates to drive each involute guide through hole 3321 to rotate, and each top post 333 is forced to move and slide in the corresponding guide groove 3311, thereby realizing synchronous inward folding or outward expansion movement of the plurality of inner support clamping blocks 32.

By adopting the structure of the invention, the synchronous inward folding or outward extending movement of the plurality of inner supporting clamping blocks 32 can be realized by the forward and reverse rotation of the inner clamping driven member 31, and a group of inner clamping driven members 31 and inner clamping driving mechanisms 33 do not need to be independently configured for each inner supporting clamping block 32, thereby improving the integration effect of the device.

As shown in fig. 2, 8-10, in some embodiments, the inner ring stopper 5 includes an inclined section 51, and the pressing surface of the inclined section 51 gradually changes from back to front to its terminal end in a manner of gradually increasing the distance from the horizontal plane passing through the central axis of the telescopic end, in this embodiment, the pressing surface of the inclined section 51 gradually increases from back to front.

As shown in fig. 2, the inner ring return spring is preferably a first torsion spring 335, the first torsion spring 335 is sleeved on the first rotating shaft 3343, and two ends of the first torsion spring 335 are respectively connected with the inner clamping follower 31 and the telescopic end. In the process of extending and retracting the telescopic end from back to front, when the inner clamping driven member 31 moves to contact with the starting end of the inclined section 51, one end of the inner clamping driven member 31 (i.e. one end of the inner clamping driven member 31 is the top end of the inner clamping driven member 31 in this embodiment; one end of the inner clamping driven member 31 can also be represented as the contact end of the inner clamping driven member 31 contacting with the inner ring braking member 5) is blocked by the starting end of the inclined section 51, so that the inner clamping driven member 31 rotates forward until the end surface of one end of the inner clamping driven member 31 abuts against the abutting surface of the inclined section 51, and the inner clamping driven member 31 rotates forward to the maximum forward rotation angle. When the inner clamping follower 31 moves from back to front to the process that the end surface of one end of the inner clamping follower 31 contacts with the pressing surface of the inclined section 51, the first torsion spring 335 moves to return to drive the inner clamping follower 31 to rotate reversely gradually.

The forward rotation of the inner clamping follower 31 in the present invention is referred to the forward rotation of one end of the inner clamping follower 31 (i.e., the tip of the inner clamping follower 31 or the contact end of the inner clamping follower 31), and the reverse rotation of the inner clamping follower 31 in the present invention is referred to the reverse rotation of one end of the inner clamping follower 31 (i.e., the tip of the inner clamping follower 31 or the contact end of the inner clamping follower 31).

In the process of extending movement from the rear end to the front end, when the inner clamping driven member 31 moves to contact with the starting end of the inclined section 51, one end of the inner clamping driven member 31 is blocked by the starting end of the inclined section 51 and rotates forwards until the end surface of one end of the inner clamping driven member 31 abuts against the abutting surface of the inclined section 51, and in the process, the first torsion spring 335 deforms; meanwhile, in this period, when the inner clamping driven member 31 rotates forward until the clamping end of the inner supporting clamping block 32 contacts with the inner wall 101 of the annular part of the automobile and clamps the annular part of the automobile, the first time starts to be reached, and when the end surface of one end of the inner clamping driven member 31 just abuts against the abutting surface of the starting end of the inclined section 51, the inner clamping driven member 31 rotates forward by the maximum forward rotation angle. Then, in the process that the inner clamping follower 31 moves from back to front to the contact between the end face of one end thereof and the pressing surface of the inclined section 51, since the pressing surface of the inclined section 51 gradually changes from back to front to the end thereof in a manner that the distance between the pressing surface and the horizontal plane passing through the central axis of the telescopic end gradually increases, the first torsion spring 335 gradually resets to drive the inner clamping follower 31 to reversely rotate.

In the process of the telescopic end contracting and resetting from front to back, the inner clamping driven member 31 is forced to rotate forwards gradually to the maximum forward rotation angle in the process of moving the inner clamping driven member 31 on the abutting surface of the inclined section 51 from front to back. Then, in the process that the inner holding follower 31 is disengaged from the start end of the inclined section 51, the inner holding follower 31 is reversely rotated to be reset.

In the process that the pressing surface of the inclined section 51 moves from back to front, the limit of reverse reset rotation of the inner clamping driven member 31 cannot enable the pressing surfaces of the inner clamping driven member 31 and the inclined section 51 to be vertical, so that the movement of the inner clamping driven member 31 is disordered in the process that the telescopic end moves from front to back.

Further, the initial time of inner ring clamping is the position where the forward rotation of the inner clamping follower 31 has not reached the maximum forward rotation angle, that is, the first time and the second time are concentrated in the time period of the time period when the inner clamping follower 31 moves from back to front and rotates forward to the previous time when the plurality of inner supporting clamping blocks 32 can just clamp the annular part of the automobile until the inner clamping follower 31 moves from back to front on the inclined section 51 and rotates backward to the time when the inner supporting clamping blocks 32 just cannot clamp the annular part of the automobile, and the third time exists in the time period after the second time and when the inner clamping follower 31 moves from back to front on the inclined section 51.

Further, an end surface of one end of the inner holding follower 31 is an arc surface which is upwardly arched.

Similarly, when the inner clamping follower 31 moves from front to back in the process of returning, the third returning time exists in the time period from front to back in the process of moving the inner clamping follower 31 on the abutting surface of the inclined section 51 until the inner clamping follower 31 rotates forward again to the previous time of the time when the inner clamping block 32 can clamp the automobile annular part right, and the second returning time and the first returning time are concentrated in the time period from the next time of the third returning time to the previous time when the inner clamping follower 31 rotates backward again to the time when the inner clamping block 32 cannot clamp the automobile annular part right.

As shown in fig. 2-5, 11-13, in some embodiments, the outer ring brake 6 is preferably an outer ring brake rack 61, the outer clamping follower 41 is preferably an outer clamping gear 411, the outer clamping gear 411 is in communication with the corresponding outer clamping drive mechanism 43 and the outer clamping gear 411 is in engagement with the corresponding outer ring brake rack 61. An extending hole 213 is formed in the surface of the telescopic end, the extending hole 213 is communicated with the cavity 211, and the extending holes 213 are annularly distributed around the central axis of the telescopic end. The outer clamp driving mechanism 43 includes an outer rotating rod 4321 and an outer transmission rod 4322. One end of the outer rotation rod 4321 is fixedly connected to one end of the outer clamping gear shaft 4323, the other end of the outer clamping gear shaft 4323 is fixedly connected to the outer clamping gear 411, the outer clamping gear shaft 4323 is rotatably engaged with the chamber 211, the other end of the outer rotation rod 4321 is hinged to one end of the outer transmission rod 4322, the other end of the outer transmission rod 4322 is hinged to the outer pressing clamping rod 42, the outer pressing clamping rod 42 is connected to the second rotation shaft 4324, the second rotation shaft 4324 is rotatably engaged with the chamber 211, and one end of the outer pressing clamping rod 42 (i.e., the clamping end of the outer pressing clamping rod 42) extends out of the corresponding extending hole 213. The external pressure clamping rods 42 and the protruding holes 213 are the same in number and are in one-to-one correspondence. In this embodiment, when the telescopic end moves from back to front, the angle of rotation of the outer clamping gear 411 can maintain the clamping end of the outer pressure clamping rod 42 to rotate continuously inwards; specifically, the outer clamping gear 411 rotates forward, so as to drive the outer clamping gear shaft 4323 and the outer rotating rod 4321 to rotate, and the clamping end of the outer pressure clamping rod 42 is folded inwards through transmission of the outer transmission rod 4322; similarly, when the outer clamping follower 41 moves from front to back, the clamping end of the outer pressure clamping rod 42 expands outward.

It should be noted that, the clamping adjustable automobile annular part mounting platform of the present invention is also used for mounting other prior art annular parts, such as home decoration, cast, injection molded plastic annular parts or metal annular parts, and shall fall within the protection scope of the present invention.

Due to the different directions in which the different outer clamping followers 41 are located, the actual turning directions of the different outer clamping followers 41 at the same time may be opposite due to the different reference systems. Therefore, the reference object of the forward and reverse rotation of the outer clamping follower 41 in the present invention is the outer ring stopper 6 corresponding to the outer clamping follower 41. For example, as shown in fig. 13, when the telescopic end moves from back to front, i.e., when fig. 13 moves from right to left, at the same time, in fig. 13, the forward rotation of the outer clamping gear 411 located at the upper position is clockwise rotation, and the forward rotation of the outer clamping gear 411 located at the lower position is counterclockwise rotation, however, the outer clamping gear 411 located at the upper position and the outer clamping gear 411 located at the lower position respectively correspond to the outer ring braking rack 61 which rolls close to the terminating end (i.e., the left end in fig. 13) of the respectively corresponding outer ring braking rack 61. Therefore, the direction of the forward rotation of the outer gripping gear 411 is the direction in which the outer gripping gear 411 rolls toward the terminal end of the corresponding outer ring stopper 6. The direction of the reverse rotation of the outer holding gear 411 is a direction in which the outer holding gear 411 rolls toward the starting end (i.e., the right end in fig. 13) of the corresponding outer ring stopper 6.

In some embodiments, the inner support clamp block 32 and the outer pressure clamp rod 42 are both deformable clamps.

As shown in fig. 3, the inner support clamping block 32 preferably comprises an inner support clamping block body 321 and an inner rubber layer 323 connected to the inner support clamping block body 321. The external pressure clamping rod 42 includes an external pressure clamping rod body 421 and an outer rubber layer 423 connected to the external pressure clamping rod body 421.

When the inner ring is clamped, the inner rubber layer 323 on the inner support clamping block 32 is in pressing contact with the inner wall 101 of the automobile annular part; the outer rubber layer 423 of the external pressure clamping rod 42 is in pressing contact with the outer wall 102 of the automobile annular part at the time of outer ring clamping.

As shown in fig. 13, the inner support holding block 32 is preferably a deformable holding block, and the deformation occurs at the holding end of the inner support holding block 32. The inner supporting clamping block 32 comprises an inner supporting clamping block body 321 and an inner elastic part 322 connected to the inner supporting clamping block body 321, and when the inner ring is clamped, the inner elastic part 322 is in pressing contact with the inner wall 101 of the automobile annular part.

The outer elastic member 422 or the outer rubber layer 423 and one end of the external pressure clamping rod body 421 to which the outer elastic member 422 or the outer rubber layer 423 is connected form a clamping end of the external pressure clamping rod 42. The inner elastic element 322 or the inner rubber layer 323 and one end of the inner supporting clamping block 32 connected with the inner elastic element 322 or the inner rubber layer 323 form a clamping end of the inner supporting clamping block 32.

In some embodiments, the clamping end of the external pressure clamping rod body 421 is a bent structure, and the bent structure is pressed against the outer wall 102 of the annular part of the automobile when the outer ring is clamped.

Preferably, the external pressure clamping bar 42 is a deformable clamping bar, and the deformation occurs at the clamping end of the external pressure clamping bar 42. The external pressure clamping rod 42 comprises an external pressure clamping rod body 421 and an outer elastic member 422 connected to the external pressure clamping rod body 421, and when the outer ring is clamped, the outer elastic member 422 is in pressing contact with the outer wall 102 of the automobile annular part.

Preferably, the outer elastic member 422 and the inner elastic member 322 are compression springs.

As shown in fig. 14, the outer elastic member 422 preferably includes an outer compression spring 4221 and an outer contact 4222 coupled to the outer compression spring 4221. The inner elastic member 322 includes an inner compression spring 3221 and an inner contact 3222 coupled to the inner compression spring 3221.

When the inner ring is clamped, the inner contact body 3222 on the inner elastic piece 322 is in contact with the inner wall 101 of the automobile annular part; the outer contact 4222 on the outer spring 422 contacts the outer wall 102 of the vehicle ring part when the outer ring is clamped.

In some embodiments, a material receiving groove with an upward opening is arranged below the telescopic end, and when the telescopic end is retracted from front to back until the inner supporting clamping blocks 32 are folded inwards to be separated from the inner wall 101 of the annular automobile part, the annular automobile part falls down into the material receiving groove.

Preferably, a soft cushion is arranged in the material receiving groove. The soft cushion can be made of sponge.

Compared with the prior art, the invention has the following technical effects: firstly, when the automobile annular part is clamped and installed by adopting the clamping adjustable automobile annular part installation platform, only inner ring clamping, inner ring clamping and outer ring clamping and only outer ring clamping are sequentially realized in the single extension motion process of the telescopic end of the telescopic device 2, and the simultaneous inner ring clamping and outer ring clamping are used as intermediate links for connecting only the inner ring clamping and the outer ring clamping, so that the staggered realization of the inner wall 101 clamping and the outer wall 102 clamping of the automobile annular part is realized on the premise of no process interruption, the continuity of industrial processing is improved, and the processing efficiency is improved; secondly, the extension movement of the telescopic end of the telescopic device 2 can realize feeding, and by matching with the clamping action, the feeding when only inner ring clamping exists on the automobile annular part is realized, the continuous clamping process is switched to the outer ring clamping, the release of the automobile annular part can be realized in the contraction resetting process of the telescopic end, the blanking is further facilitated, and the sequential realization of the feeding, the clamping and the blanking is realized; thirdly, because only the inner ring clamping and only the outer ring clamping are arranged at different positions, when the inner wall 101 and the outer wall of the automobile annular part are respectively subjected to post-processing such as spraying, polishing or diameter measurement, the post-processing device corresponding to the inner wall 101 of the automobile annular part and the post-processing device corresponding to the outer wall 102 of the automobile annular part can be arranged in a staggered manner in space (namely, arranged in a staggered manner from front to back), so that the phenomenon that the devices are crowded and interfere with each other due to the concentrated arrangement of two groups of post-processing devices is prevented; fourthly, when the mounting platform is used for clamping, the front side surface and the rear side surface of the automobile annular part can be always exposed to the outside, and the processing on the front side surface and the rear side surface of the automobile annular part is not influenced; fifthly, the clamping ends of the plurality of inner supporting clamping blocks 32 are expanded outwards to form flaring openings, so that inner supporting force is applied to different positions, namely a plurality of angle directions, of the inner wall 101 of the automobile annular part, and stable and firm clamping force is achieved when the inner ring is clamped; similarly, the clamping ends of the external pressure clamping rods 42 are folded inwards to form a necking, so that external pressure is applied to different positions, namely a plurality of angle directions, of the outer wall 102 of the automobile annular part, and the outer ring has stable and firm clamping force when being clamped; sixthly, because the inner supporting clamping block 32 and the outer pressure clamping rod 42 are positioned at the front end of the telescopic end in industrial application, the movement state of the inner supporting clamping block and the outer pressure clamping rod is difficult to change spontaneously, and the inner supporting clamping block and the outer pressure clamping rod are required to participate in clamping, so that the independence of the inner supporting clamping block and the outer pressure clamping rod in the movement process is required to be kept and is not interfered; in the process of moving back and forth, the matching state of the inner clamping driven member 31 and the inner ring braking member 5 is changed by utilizing the change of the mutual position between the inner clamping driven member 31 and the inner ring braking member 5, the matching state of the outer clamping driven member 41 and the outer ring braking member 6 is changed by utilizing the change of the mutual position between the outer clamping driven member 41 and the outer ring braking member 6, and the change of the state is respectively and indirectly converted and mapped to the change of the motion states of the inner supporting clamping block 32 and the outer pressure clamping rod 42, so that the accuracy, the reliability and the independence of the motion change of the inner supporting clamping block 32 and the outer pressure clamping rod 42 are achieved.

Example 2

As shown in fig. 3 and 11, the present embodiment is different from the above embodiments in that the present embodiment further includes a position-limiting sleeve 71, and the position-limiting sleeve 71 is sleeved on the periphery of the telescopic end. The inner wall of the limiting sleeve 71 is provided with a front-back guiding limiting sliding groove 711, the surface of the telescopic end is provided with a sliding strip 214, and the sliding strip 214 extends into the limiting sliding groove 711 and is in sliding fit with the limiting sliding groove 711. The inner ring braking part 5 and the outer ring braking part 6 are both fixed on the limiting sleeve 71.

The structure of the limiting sleeve 71 and the matching mode of the limiting sleeve 71 and the telescopic end can provide point positions for the installation of the inner ring braking part 5 and the outer ring braking part 6 on one hand, and ensure that the telescopic end can move back and forth while the limiting sleeve 71 is relatively fixed; on the other hand, the telescopic end can rotate to drive the limiting sleeve 71 to rotate synchronously.

Example 3

As shown in fig. 17 to 19, the present embodiment is different from the above-described embodiments in that: the inner ring brake 5 comprises a horizontal section 52 and an inclined section 51 from back to front in sequence. The terminating end of the horizontal section 52 is connected to the starting end of the inclined section 51. The pressing surface of the horizontal section 52 is parallel to the central axis of the telescopic track of the telescopic end (i.e. the height of the pressing surface of the horizontal section 52 is constant in this embodiment), the pressing surface of the inclined section 51 gradually changes from back to front to the end in a manner that the distance between the pressing surface of the inclined section 51 and the horizontal plane passing through the central axis of the telescopic end gradually increases, and in this embodiment, the pressing surface of the inclined section 51 gradually increases from back to front.

In the process of extending and moving the telescopic end from back to front, when the inner clamping driven member 31 moves to contact with the starting end of the horizontal section 52, one end (i.e. the top end or the contact end) of the inner clamping driven member 31 is blocked by the starting end of the horizontal section 52, so that the inner clamping driven member 31 rotates forward until the end of one end of the inner clamping driven member 31 abuts against the starting end of the abutting surface of the horizontal section 52, and the inner clamping driven member 31 rotates forward to the maximum forward rotation angle. When the inner clamping follower 31 moves from back to front until one end of the inner clamping follower abuts against the abutting surface of the horizontal section 52, the inner clamping follower 31 keeps the maximum forward rotation angle. When the inner clamping follower 31 moves from back to front until one end of the inner clamping follower contacts with the pressing surface of the inclined section 51, the first torsion spring 335 returns to move to drive the inner clamping follower 31 to rotate in reverse direction gradually.

The process of the telescopic end shrinking and resetting from front to back, and the inner clamping driven piece 31 rotates forwards to the maximum forward rotation angle gradually under stress in the process of the inner clamping driven piece 31 moving from front to back on the pressing surface of the inclined section 51. The inner clamping follower 31 keeps the maximum forward rotation angle during the movement of the inner clamping follower 31 from front to back on the pressing surface of the horizontal section 52. When the inner clamping follower 31 is disengaged from the horizontal section 52, the first torsion spring 335 is reset to rotate the inner clamping follower 31 reversely to reset.

When the inner clamping driven member 31 rotates to the maximum forward rotation angle, the inner supporting clamping blocks 32 move until only the inner ring clamping exists, namely, the inner supporting clamping blocks 32 can clamp the annular part of the automobile. Therefore, the first time and the second time are concentrated on the time period in which the inner clamp follower 31 moves on the horizontal section 52 from the rear to the front. The third time exists within which the clamping follower 31 moves on the inclined section 51 from back to front for a period of time. The third reset time is that the internal clamping follower 31 moves on the inclined section 51 from front to back to a time period; the second reset time, the first reset time, is concentrated on the time period during which the inner clamp follower 31 moves on the horizontal section 52 from front to back. Compared with the motor driving the first rotating shaft 3343 to rotate, the numerical control point positions are reduced. Such an inner ring detent 5, including horizontal segment 52, allows the inner support retainer 32 to be a deformable retainer and may also allow the inner support retainer 32 to be a rigid non-deformable retainer. When the inner supporting clamping block 32 is a deformable clamping block, the clamping end of the inner supporting clamping block 32 for clamping the automobile annular part is pressed against the inner wall 101 of the automobile annular part and is extruded and deformed. When the inner supporting clamping block 32 is a rigid and non-deformable clamping block, which clamps the annular part of the automobile, the clamping end of the inner supporting clamping block 32 is pressed against the inner wall 101 of the annular part of the automobile.

Example 4

The present embodiment is different from the above-described embodiments in that the outer clamping gear 411 rotates once so that the outer pressure clamping rod 42 reciprocates once in the forward and reverse rotation (i.e., oscillates once in a reciprocating manner). Therefore, it is possible to realize that the outer clamping gear 411 rotates at an angle such that the outer pressure clamping rod 42 rotates in the forward direction first and then in the reverse direction when the telescopic end performs one extension movement from the rear to the front. When the external pressure clamping rod 42 moves from back to front and reversely rotates, the clamping end of the external pressure clamping rod 42 expands outwards, so that the phenomenon that the external ring and the inner ring cannot be clamped when the external ring is clamped to the back and the telescopic end continues to extend forwards can be realized, and the blanking is allowed to occur in the stage that the telescopic end extends forwards instead of the stage that the telescopic end contracts backwards. And then realize flexible end single extension motion, realize only having inner ring centre gripping (material loading), having inner ring centre gripping and outer ring centre gripping simultaneously, only having outer ring centre gripping, not having inner ring centre gripping and outer ring centre gripping simultaneously (unloading) in order.

Further, the telescopic end extends forwards to a position below the position where the inner ring clamping and the outer ring clamping do not exist at the same time, and a material receiving groove with an upward opening is arranged.

Example 5

As shown in fig. 20, the present embodiment is different from the above embodiments in that an incomplete gear 4325 is connected to the outer clamping gear shaft 4323 in addition to the outer clamping gear 411, the incomplete gear 4325 can be engaged with the driven gear 4326, the driven gear 4326 is sleeved on the driven rotating shaft 4327, the driven rotating shaft 4327 is rotatably engaged with the cavity 211, the driven gear 4326 is engaged with the reversing gear 4328, the reversing gear 4328 is sleeved on the reversing gear rotating shaft 4329, and the outer rotating rod 4321 is connected to the reversing gear rotating shaft 4329 instead of the outer clamping gear shaft 4323 of the above embodiments. Thus, when the clamping ends of the external pressure clamping rods 42 are inwardly folded to the position where the clamping ends of the external pressure clamping rods 42 just clamp the annular part of the automobile, the incomplete gear 4325 just rotates to the position where the incomplete gear 4326 is not meshed, and at this time, the outer convex arc section of the incomplete gear 4325 is in sliding fit with the inner groove of the tooth crest of the driven gear 4326.

The outer clamping driving mechanism 43 including the partial gear 4325 of this embodiment allows the outer pressure clamping bar 42 to be a deformable clamping bar, and also allows the outer pressure clamping bar 42 to be a rigid non-deformable clamping bar. When the external pressure clamping rod 42 is a deformable clamping rod, the external pressure clamping rod clamps the automobile annular part, and when the clamping end of the external pressure clamping rod 42 is pressed against the outer wall 102 of the automobile annular part and is extruded and deformed. When the external pressure clamping rod 42 is a rigid and non-deformable clamping rod, and clamps the annular part of the automobile, the clamping end of the external pressure clamping rod 42 is pressed against the outer wall 102 of the annular part of the automobile.

Example 6

As shown in fig. 24 and 25, the present embodiment is different from the above embodiments in that the telescopic end includes a telescopic rotating end 21 and a telescopic fixing end 22. The telescopic rotating end 21 is rotatably matched with the telescopic fixed end 22 through a first bearing. The guiding hole 212, the protruding hole 213, the cavity 211 and the sliding bar 214 are all arranged at the telescopic rotating end 21, and the inner supporting clamping block 32, the outer pressure clamping rod 42, the inner clamping driven member 31, the outer clamping driven member 41, the inner clamping driving mechanism 33 and the outer clamping driving mechanism 43 are matched with the telescopic rotating end 21.

The device also comprises a base 72, wherein the base 72 is fixed on the mounting base 1, and the base 72 is in rotating fit with the limiting sleeve 71 through a second bearing.

Further, a first gear 23 is provided at the telescopic rotary end 21, a second gear 73 is provided at an output shaft end of the first motor, and the first gear 23 and the second gear 73 are always engaged with each other when the telescopic rotary end 21 moves forward and backward.

The first motor is driven to rotate, the telescopic rotating end 21 can rotate, and when the outer ring is clamped or the inner ring is clamped, the telescopic rotating end 21 rotates to drive the automobile annular part to rotate.

Example 7

As shown in fig. 25 to 27, the present embodiment discloses a sander based on the adjustable automotive annular part mounting platform of embodiment 5 above, when there is only inner ring clamping, the clamped automotive annular part can move forward to a position where its outer wall 101 is opposite to the first grinding stones 81 of the first sander. When only the outer ring clamp is present, the clamped automotive ring part can be moved forward to a position where its inner wall 102 is opposed to the second grinding heads 82 of the second grinding machine.

Because the inner ring clamping and the outer ring clamping are positioned at different positions, when the inner wall 101 and the outer wall of the automobile annular part are respectively subjected to post-treatment such as spraying, polishing or diameter measurement, the first grinding machine and the second grinding machine can be arranged in a staggered mode in space (namely, arranged in a staggered mode in the front-back direction), and the phenomenon that the two grinding machines are arranged in a concentrated mode to cause the device to be crowded and cause mutual interference is avoided.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
