Referring to fig. 1 to 3, the threaded fastener dismounting device provided in the present embodiment includes: cartridge assembly 100, drive shaft 200, and drive mechanism 400. The connection relationship and the action of the above components will be described in detail below.
Further, the specific direction employed in the following description is the same as the direction shown in fig. 1 to 3, that is, "the first end" in the following description is "the upper end" in fig. 1 to 3, and "the second end" in the following description is "the lower end" in fig. 1 to 3.
The driving shaft 200 is provided inside the cartridge assembly 100 described below and includes a first shaft portion 210 and a second shaft portion 220, and the second shaft portion 220 may be formed with a hole portion extending along a longitudinal direction thereof, and in order to prevent vibration of the screw fastener attaching and detaching device due to eccentricity of the driving shaft 200 from occurring when in use, the hole portion in the present embodiment is opened along an axis of the second shaft portion 220, so that it has good assembly centering property. The second shaft portion 220 may have a second slot 222 formed at a side thereof and extending along a longitudinal direction thereof, and the second shaft portion 220 in this embodiment includes two second slots 222 for cooperating with a third stopper 211 described below.
In this embodiment, the first shaft portion 210 can be slidably installed in the hole portion of the second shaft portion 220, the first shaft portion 210 can be formed with a third position-limiting portion 211, and the third position-limiting portion 211 can penetrate through the second slot 222 and can slide along the second slot 222. The number of the third position-limiting portions 211 may correspond to the number of the second slots 222, that is, two third position-limiting portions 211 are formed on the first shaft portion 210.
In this embodiment, the two third position-limiting portions 211 are two ends of a pin, and the diameter of the pin may be equal to the width of the second slot 222 (i.e. the distance between two edges of the second slot 222 along the horizontal direction), that is, the side portion of the second end of the first shaft portion 210 is provided with a through hole, and after the first shaft portion 210 is inserted into the hole portion of the second shaft portion 220, the first end of the pin may sequentially penetrate through the first second slot 222, the through hole of the side portion of the second end of the first shaft portion 210, and the second slot 222. In this embodiment, the outer peripheral edge of the second end of the pin shaft is formed with a protrusion capable of being clamped with the first second slot hole 222, in this embodiment, the first end of the pin shaft after the installation process is completed is provided with a limiting snap ring, and the limiting snap ring can be clamped with the second slot hole 222, so that two ends of the pin shaft respectively penetrate through the two second slot holes 222, and the situation that the pin shaft is separated from the first slot hole 222 is avoided.
Through the above assembling process, under the cooperation of the pin and the second slot 222, the two ends of the pin slide along the two second slots 222 respectively, so that the first shaft 210 will not be separated from the second shaft 220 when sliding; in addition, since the diameter of the pin shaft is equal to the width of the second slot 222, the first shaft 210 is prevented from rotating under the driving of the driving mechanism 400, and further the second shaft 220 is driven to rotate, so that the "idle stroke" of the rotation transmission occurs, and the two ends of the pin shaft are further prevented from frequently impacting the edges of the two second slots 222 to reduce the service life of the second shaft 220. In addition, due to the arrangement of the protrusion at the second end of the pin shaft and the limiting snap ring, the pin shaft limits the second shaft part 220 in the horizontal plane, and the second shaft part 220 is prevented from swinging relative to the first shaft part 210.
Further, the transmission shaft 200 further includes a second spring member 230, as shown in fig. 2, a first end of the first shaft portion 210 is formed with a protruding end flange, a first end of the second spring member 230 abuts the end flange of the first shaft portion 210, and a second end of the second spring member 230 abuts the first end of the second shaft portion 220. The second spring member 230 in this embodiment may be a compression spring, a first end of which abuts against an end flange of the first end of the first shaft portion 210, and a second end of which abuts against a first end of the second shaft portion 220. The abutment referred to herein means that the compression spring is always in a compressed state and continuously applies force to the portions where both ends abut, that is, the transmission shaft 200 including the first shaft portion 210 and the second shaft portion 220 which are slidable relative to each other is always kept in the longest length state due to the presence of the compression spring when the screw fastener attaching and detaching device is not in operation.
According to the above-described features, the first end of the transmission shaft 200 is the first end of the first shaft portion 210, and the second end of the transmission shaft 200 is the second end of the second shaft portion 220. The second end of the drive shaft 200 (i.e., the second end of the second shaft portion 220) is mounted with a standard bit 223 for engaging with a clamped portion of the threaded fastener (e.g., when the threaded fastener is a screw, the clamped portion is a head of the screw), and the standard bit 223 is rotated by the drive of the drive shaft 200, thereby mounting and dismounting the threaded fastener. In this embodiment, the second end of the second shaft portion 220 is formed with a standard batch head groove, the size of which is standardized as the standard batch head 223, so that the standard batch head 223 can be replaced quickly.
However, without being limited thereto, in the above-described feature, it is also possible that the first shaft portion 210 forms a hole portion in which the second shaft portion 220 is slidably fitted and the second slot hole 222.
In addition, the second spring member 230 may be mounted in a hole, that is, in the above-described mounting manner, a first end of the compression spring abuts against the second end of the first shaft portion 210, and a second end of the compression spring abuts against the second end of the second shaft portion 220.

The drive mechanism 400 in this embodiment may include a reduction motor 410 and a housing 420 surrounding the reduction motor 410. The speed reducing motor 410 has the functions of adjustable torque, adjustable rotating speed, adjustable forward and reverse rotation and torque overload protection, and can effectively meet the requirements of the dismounting condition and the reliability of the threaded fastener.
The output shaft of the speed reduction motor 410 is fixedly connected with the first end of the first shaft portion 210, the connection mode of the speed reduction motor 410 can be that the speed reduction motor 410 with the square head output shaft is selected, the square hole is formed in the first end of the first shaft portion 210, and the square head output shaft is inserted into the square hole. Further, a through hole penetrating the first shaft portion 210 may be formed at an outer side portion of the square hole at the first end of the first shaft portion 210, a through hole may be formed at a position corresponding to the output shaft of the reduction motor 410, and in addition to the above connection, two through holes may be formed by a pin to further ensure the reliability of the connection.
The square head and the square hole connection mode are adopted, so that the driving mechanism 400 can be conveniently detached and installed, and in addition, the output shaft of the speed reducing motor 410 and the first end of the first shaft part 210 can be connected through the coupler.
In this embodiment, the housing 420 for housing the geared motor 410 may be fixedly connected to the geared motor 410, on one hand, the housing 420 may be fixedly connected to the following cartridge assembly 100, so as to mount the geared motor 410 to the first end of the cartridge assembly 100, and on the other hand, the housing 420 may mount the threaded fastener mounting and dismounting device to a robot arm or other equipment, in this embodiment, a robot arm, so that the geared motor 410 may be externally connected to a power source, and the threaded fastener mounting and dismounting device may be moved under the control of the robot arm, thereby performing the mounting and dismounting of the threaded fastener.
In this embodiment, the inner cylinder 110 may be provided with two second position-limiting parts 112, the side part of the outer cylinder 120 may correspondingly form two first slots 121, the second position-limiting parts 112 may be threaded cylindrical pins, and a first end of the threaded cylindrical pins may have external threads, and the diameter of the external threads may be equivalent to the width of the first slots 121 (i.e., the distance between two edges of the first slots 121 in the horizontal direction). The first end of the inner cylinder 110 can be respectively provided with two internal threaded holes corresponding to the two first slots 121, when the outer cylinder 120 is sleeved on the outer side of the inner cylinder 110, the first end of the threaded cylindrical pin penetrates through the first slots 121 and is screwed into the internal threaded holes, and the second end of the threaded cylindrical pin can slide in the first slots 121, so that the outer cylinder 120 can slide relative to the inner cylinder 110 without being disengaged.
In addition, the diameter of the selected threaded cylindrical pin is equivalent to the width of the first slotted hole 121, so that the first slotted hole 121 limits the threaded cylindrical pin in the horizontal direction, and the outer cylinder 120 is prevented from twisting relative to the inner cylinder 110 to influence the disassembly and assembly of the threaded fastener.
In this embodiment, cartridge assembly 100 further includes a first spring member 130. A first end of the first spring member 130 may abut against the reduction motor 410, and a second end of the first spring member 130 may abut against the inner cylinder 110. The first spring member 130 in this embodiment may be a compression spring, and specifically, a first end thereof may abut against the reduction motor 410, and a second end thereof may abut against the first end of the inner cylinder 110. The meaning of the abutment referred to herein is the same as that of the abutment described above in the description of the second spring member 230, and is not described herein again.
In this case, the entirety composed of the reduction motor 410, the housing 420 and the outer cylinder 120 in the present embodiment can be supported due to the presence of the first spring member 130, so that the cartridge assembly 100 including the outer cylinder 120 and the inner cylinder 110 which can slide with each other is maximized in length when the threaded fastener attaching and detaching means is not operated.
In the above-described installation, the first end of the outer cylinder 120 is the first end of the cartridge assembly 100, and the second end of the inner cylinder 110 is the second end of the cartridge assembly 100.
However, not limited thereto, the second end of the outer cylinder 120 and the first end of the inner cylinder 110 may be capable of being engaged with each other, and the shape of the outer side of the inner cylinder 110 and the shape of the inner side of the outer cylinder 120 may preferably be polygonal. This arrangement also satisfies the requirements for the arrangement of the first slot 121 and the threaded cylindrical pin, which will be described in detail below.
The inner side of the second end of the outer cylinder 120 may be formed with an inward protrusion, the outer side of the first end of the inner cylinder 110 may be formed with an outward protrusion, and the inner cylinder 110 is assembled to the inner side of the outer cylinder 120 from above the outer cylinder 120, and when the first end of the inner cylinder 110 slides to the second end of the outer cylinder 120, the inner protrusion and the outer protrusion may be engaged with each other to prevent the inner cylinder 110 from falling off the outer cylinder 120, and on this basis, the outer side of the inner cylinder 110 and the inner side of the outer cylinder 120 may be formed in a polygonal shape, for example, a rectangular parallelepiped shape, in which case, even in the absence of the second stopper 112 and the first groove 121 which are engaged with each other, the inner cylinder 110 and the outer cylinder 120 do not twist when sliding relative to each other.
The shape of the outer portion of the inner tube 110 and the shape of the inner portion of the outer tube 120 may be polygonal prisms, but the shape of the inner portion of the inner tube 110 and the shape of the outer portion of the outer tube 120 may be other shapes. The shape of the outer portion of the inner tube 110 and the shape of the inner portion of the outer tube 120 do not need to be polygonal columns having the same shape, and it is sufficient that the outer tube 120 is fitted to the inner tube 110 and does not twist.
In this embodiment, cartridge assembly 100 further includes a staple cartridge 140. The clip cartridge 140 in this embodiment has an approximately funnel shape, and a first end thereof is connected to a second end of the inner cylinder 110 (i.e., a second end of the cartridge assembly 100) in a plugging manner, and a second end thereof is formed with a clamping portion 141. In this embodiment, the nail clamping cylinder 140 having the clamping portions 141 with different sizes can be selected according to the size of the clamped portion of the threaded fastener to be mounted or dismounted, and since the nail clamping cylinder 140 is inserted into the second end of the inner cylinder 110, in this case, the nail clamping cylinder 140 having the clamping portions 141 with different sizes can be replaced quickly according to actual needs.
However, without limitation, the above-mentioned clip cartridge 140 can be mounted on the second end of the inner cylinder 110 by other detachable quick connection means, such as a screw connection.
In this embodiment, a plurality of through holes are formed in the side portion of the clamping portion 141, rolling bodies are disposed in the through holes, and the side portion of the clamping portion 141 is tightly wrapped with the elastic sleeve 143 so that the rolling bodies abut against the elastic sleeve 143. As shown in fig. 3, the rolling element in this embodiment may be a ball 142, the through hole may be a stepped hole, and a diameter of the stepped hole at an end toward the inside of the clamping portion 141 is gradually reduced to ensure that a portion of the ball 142 is exposed to the inside of the clamping portion 141 while not coming out of the stepped hole. The elastic sleeve 143 in this embodiment may be a spring clip or a rubber sleeve, and the elastic sleeve 143 continuously applies elastic force to the ball 142 such that the ball 142 is pressed against the elastic sleeve 143.
In this embodiment, the through holes and the balls 142 are uniformly distributed on the same horizontal plane of the periphery of the clamping portion 141, so as to ensure that the clamped portion of the threaded fastener is uniformly stressed during clamping, and can be stably clamped.
When the clamped portion of the threaded fastener enters the clamping portion 141, the portion of the ball 142 exposed to the clamping portion 141 is forced to roll and move toward the elastic sleeve 143, so that the clamped portion of the threaded fastener is finally clamped between the balls 142.
According to the above-described feature, when the clamped portion of the threaded fastener is clamped to the clamping portion 141, since the threaded fastener is raised and lowered with respect to its mounting plane during the dismounting and mounting processes, respectively, there is a possibility that the clamped portion of the threaded fastener is separated from the clamping portion 141, resulting in unstable clamping.
Therefore, in the present embodiment, the inner portion of the inner cylinder 110 (i.e., the inner portion of the cartridge assembly 100) is further provided with a first stopper portion 111 and a rotational support 221, and the rotational support 221 is engaged with the first stopper portion 111 and is provided at the outer portion of the second shaft portion 220 (i.e., the outer portion of the transmission shaft 200).
As shown in fig. 2, the first limiting portion 111 in this embodiment may be two set screws, and the axes of the two set screws are disposed on the same horizontal plane, in this embodiment, the two set screws are also symmetric with respect to the axis of the inner cylinder 110, so as to make the force applied to the rotation supporting member 221 uniform and further make the force applied to the second shaft portion 220 uniform when the rotation supporting member 221 is abutted.
Based on the arrangement of the two set screws, when the length of the cartridge assembly 100 and the length of the drive shaft 200 are both maximized, the rotary support 221 is disposed below and may contact the two set screws. The rotation support 221 in this embodiment may be preferably a bearing, which is positioned and installed by a shoulder formed on the second shaft portion 220 and then limited by a circlip, and specifically, an inner ring of the bearing is fixedly installed on the shoulder of the second shaft portion 220. The position of bearing and two holding screw contacts is the outer lane of bearing, avoids influencing the bearing inner race and is interfered by two holding screws and lead to rotatory being obstructed, influences threaded fastener's dismantlement process.
The process of fitting the first stopper portion 111 and the pivoting support member 221 will be described below.
In the first movement posture of the transmission shaft 200, the transmission shaft 200 drives the standard batch head 223 and the rotary support 221 to move toward the clamping part 141 side;
in the second movement posture of the transmission shaft 200, the transmission shaft 200 drives the standard batch head 223 and the rotary support 221 to move away from the grip 141 side and toward the driving mechanism 400 side;
when the rotation supporting member 221 abuts against the first limiting portion 111 in the second movement posture, the transmission shaft 200 enters a third movement posture, and in the third movement posture, the transmission shaft 200 drives the clamping portion 141 and the standard batch head 223 to move towards the driving mechanism 400 side together.
The operation of the threaded fastener dismounting device will be described in detail below, taking a screw as an example.
The installation process comprises the following steps:
the clamping portion 141 clamps the head of the screw, the standard batch head 223 is embedded with the head of the screw, the mechanical arm control housing 420, the speed reduction motor 410 and the outer cylinder 120 descend as a whole, the outer cylinder 120 slides downwards relative to the inner cylinder 110, and in the process, the first spring member 130 continues to be compressed, so that the set screw abuts against the outer ring of the bearing. Because the standard bit 223 has been fitted with the head of the screw such that the second shaft portion 220 cannot be further lowered, the second shaft portion 220 slides relative to the first shaft portion 210, that is, the second spring member 230 continues to be compressed.
At this time, the output shaft of the reduction motor 410 starts to rotate, the driving shaft 200 is driven to rotate, and the screw starts to be driven to be screwed into the mounting plane, in the process, as the second spring member 230 is compressed all the time, the lower end of the standard screwdriver bit 223 on the second shaft part 220 continuously abuts against the head of the screw, and the continuous mounting is ensured.
As the screw is gradually screwed into the mounting plane, the second spring member 230 gradually recovers deformation so that the lower end of the standard bit 223 gradually approaches the mounting plane downwards, and the bearing on the second shaft portion 220 also gradually approaches the mounting plane, the set screw continuously abuts against the outer ring of the bearing under the action of the first spring member 130, so that the inner cylinder 110 slides downwards relative to the outer cylinder 120, and the clamping portion 141 of the clip cylinder 140 is linked with the standard bit 223 due to the fixed connection of the clip cylinder 140 and the inner cylinder 110, thereby ensuring that the relative positions of the standard bit 223 and the clamping portion 141 are unchanged.
The disassembling process comprises the following steps:
the first part of the disassembly process is the same as the installation part described above and will not be described in detail here.
When the speed reducing motor 410 rotates reversely, the driving shaft 200 is driven to rotate, the screw starts to be driven to be screwed out of the installation plane, at this time, the standard screwdriver bit 223 gradually leaves away from the installation plane, so that the second spring member 230 continues to be compressed, meanwhile, the outer ring of the bearing abuts against the set screw to drive the set screw to ascend, further, the inner cylinder 110 slides upwards relative to the outer cylinder 120, the first spring member 130 continues to be compressed, further, the nail clamping cylinder 140 and the inner cylinder 110 ascend synchronously, and further, the relative positions of the standard screwdriver bit 223 and the clamping part 141 are guaranteed to be unchanged.
Based on above-mentioned threaded fastener dismouting device's course of operation, can learn, when gear motor 410 begins to rotate and carries out the installation of screw or when dismantling with drive transmission shaft 200, the relative position of standard batch head 223 and clamping part 141 is unchangeable all the time, can guarantee that the centre gripping effect to the screw is better, has avoided the unstable condition of screw centre gripping to appear.
However, not limited thereto:
first, in this embodiment, when the screw is a countersunk head screw to be installed in the countersunk hole in the working process, in the process of mounting the countersunk head screw, taking the relative clamping position in fig. 3 as an example, when the lower end surface of the head of the countersunk head screw reaches the mounting plane, the clamping part 141 also reaches the mounting plane at this time, however, since the countersunk hole is lower than the mounting plane, the mounting process of the countersunk screw is not finished, and the reduction motor 410 continues to rotate, and the standard bit 223 continues to move downward relative to the clamping part 141, completing the mounting of the countersunk screw, that is, in this case, the relative positions of the master batch head 223 and the clamping part 141 are changed, however, when the relative position changes, a part of the thread part of the countersunk head screw is already installed, therefore, even if the head portion is separated from the grip of the grip portion 141, the reliability of the mounting process is not affected. Secondly, in this embodiment, when the threaded fastener is a bolt, such as a hexagon head bolt, the standard screwdriver bit 223 may be in a sleeve shape, that is, the inner side portion of the standard screwdriver bit 223 is matched with the head of the hexagon head bolt, when the threaded fastener is mounted or dismounted, the standard screwdriver bit 223 is sleeved on the outer side portion of the head of the hexagon head bolt, and the clamping portion 141 is clamped on the outer side portion of the standard screwdriver bit 223, so as to play a role in stably clamping.
Third, the rolling elements in this embodiment may also be needle rollers, the needle rollers are inserted into the outer periphery of the clamping portion 141 along the horizontal direction, and the axes of the needle rollers may be formed in a regular polygon shape (that is, the needle rollers are uniformly distributed) approximately along the axial direction of the clamping portion 141, and may also function as a clamped portion of the rolling clamping threaded fastener.
The above description is only a preferred embodiment of the present application, and not intended to limit the scope of the present application, and all changes that can be made in the details of the description and drawings, or directly/indirectly implemented in other related technical fields, are intended to be embraced therein without departing from the spirit of the present application.
