Description

Multi-part synchronous assembly fixture and automatic assembly device

Technical Field

The invention relates to the technical field of base station antenna radiation unit assembly in the field of mobile communication, in particular to a multi-part synchronous assembly method, a clamp and an automatic assembly device thereof.

Background

The base station antenna is widely applied to mobile communication engineering, and the stability of the antenna quality directly relates to the personal experience of each user; the antenna is internally provided with a plurality of vibrators of various types, so that the antenna can transmit and receive signals. The performance of the oscillator is related to the quality of the overall performance index of the antenna and whether the performance index can reach the standard.

For one of the die-cast oscillators, a feed sheet assembly is assembled inside the oscillator, and then the feed sheet assembly and the oscillator are welded to realize connection transmission of oscillator signals. The feed sheet assembly is characterized in that the upper part and the lower part of one feed sheet are respectively sleeved with a dielectric block, so that the assembly of the feed sheet assembly is completed, the separation of the feed sheet assembly at the assembly position and the vibrator is realized, and the correct position of the feed sheet assembly in the vibrator is fixed. The upper and lower parts of the feed sheet are respectively provided with a notch-shaped clamping position corresponding to the assembly position of the dielectric block, and after the dielectric block is assembled to the corresponding position, the dielectric block is required to rotate by 90 degrees, so that the notch of the dielectric block is matched with the feed sheet, and the dielectric block is fixed on the feed sheet, cannot move and cannot easily fall off.

When the feed sheet assembly is assembled, the upper part and the lower part of the feed sheet are required to be sleeved with the dielectric blocks respectively, but the feed sheet and the dielectric blocks required to be sleeved are small in size, so that manual assembly is adopted in actual operation. Not only the manual work is difficult to snatch, need rotate 90 degrees after the medium piece assembly in the assembling process, and manual operation is also inconvenient. The assembly efficiency is low during manual operation, and meanwhile, the fatigue is easy to occur. Meanwhile, manual operation is adopted, the condition that the vibrator is not rotated to 90 degrees exists during assembly, so that the assembly is not in place, the dielectric block is loosened and falls off in the next turnover and assembly process, and the assembly quality of the vibrator is influenced.

Disclosure of Invention

The invention aims to overcome at least one defect (deficiency) of the prior art, and provides a multi-part synchronous assembling method, a clamp and an automatic assembling device thereof, which are used for solving the problems of high labor intensity, low production efficiency, overhigh production cost and unstable assembling quality of manually and manually assembling parts of a feed sheet assembly type.

The technical scheme adopted by the invention is that a plurality of parts such as a feed sheet, 2 dielectric blocks and the like are assembled by adopting a fixture, the assembly of the feed sheets and the matched dielectric blocks is completed by one-time assembly, a positioning device is adopted in the assembly process, the assembly speed is high, the assembly is accurate, and a mechanical control one-time switch is adopted to complete the automatic assembly of one working cycle, so that the labor intensity is greatly reduced, the production efficiency and the assembly quality are improved, and the production cost is greatly reduced.

The invention provides a multi-part synchronous assembling method for positioning and assembling at least one first component and at least one second component, which comprises the following steps:

s1, placing a first component and a second component into a fixture with a clearance, sleeving the second component on the first component, and exposing part of the first component to the clearance;

and S2, pressing the part of the first component exposed to the clearance to enable the first component to be assembled and fixed in a twisting mode relative to the second component.

The invention creatively provides a fixture for completing the torsion assembly and fixation of more than two components, and solves the technical problems of complex assembly, low assembly efficiency, unstable assembly quality and high assembly cost of small-volume parts. The method comprises the steps of firstly pre-assembling and positioning parts to be assembled through a clamp, then pressing one of two parts with a twisting relationship in an assembling process through a clearance on the clamp to twist relative to the other part, establishing a correct assembling relationship between the two parts as a result of twisting, entering a complete assembling state, determining a twisting angle alpha according to a relative position relationship between the pre-assembling state and the complete assembling state of the two parts, and generally taking alpha e (0, 90 degrees).

Where multiple parts refers to one or more groups of parts, each group of parts comprising at least one first part and at least one second part, for example, a feed tab assembly for a die cast vibrator as mentioned in the background, comprising one first part and two second parts. When the fixture can complete the assembly and fixation of a plurality of groups of parts at one time, the assembly efficiency is improved by times, which is the aim of the invention, and the fixture can be correspondingly adjusted into one group for certain complex conditions that the assembly of a plurality of groups of parts cannot be completed at one time.

The first component is like a feed sheet in the feed sheet assembly and is provided with a connecting part used for being connected with the second component and a stress part which relatively protrudes out of the connecting part and is used as a pressure application acting point, and the stress part just faces the clearance on the clamp when the first component is positioned on the clamp; the second part is like a dielectric block in the feed sheet component and is sleeved on the connecting part of the first part during and after assembly.

The process that the first part and the second part are placed in and positioned on the clamp can place more than two parts into the clamp in sequence to complete preassembly, or place more than two parts into the clamp together after preassembly, and an operator selects a proper placing sequence according to actual needs.

The invention provides a multi-part synchronous assembling clamp applying the method, which is used for positioning and assembling at least one first component and at least one second component and comprises

The positioning plate is provided with a part positioning groove and a first clearance hole, the part positioning groove is used for positioning a first part and a second part which are mutually pre-sleeved, and the first clearance hole is used for partially exposing the first part; and

the pressing plate covers the positioning plate, a second clearance hole corresponding to the first clearance hole is formed in the pressing plate, and the second clearance hole is used for partially exposing the first component;

and external force is applied to the part of the first component exposed to the clearance hole through the first clearance hole or the second clearance hole, so that the first component is assembled and fixed in a twisting mode relative to the second component.

The invention completes the preassembly and positioning of parts by matching the positioning plate and the pressing plate, partially exposes one of two parts in a twisting relationship to the first clearance hole and the second clearance hole, applies pressure to the exposed parts from the first clearance hole to enable the exposed parts to twist or penetrate out of the second clearance hole or applies pressure to the exposed parts from the second clearance hole to enable the exposed parts to twist or penetrate out of the first clearance hole by means of external force, completes the twisting assembly positioning, has simple structure and convenient operation, and overcomes the technical problems of complex assembly, low assembly efficiency, unstable assembly quality and high assembly cost of parts with small volume. Whether the pressed part passes through the first clearance hole or the second clearance hole or not during or after pressing depends on the torsional angle and the size of the part or the clamp; the angle of twist is dependent on the relative positional relationship between the two components from the pre-assembled state to the fully assembled state, typically in the range of α e (0, 90 °). The external force can be applied by manually poking the exposed parts from the first clearance hole or the second clearance hole to the second clearance hole or the first clearance hole one by one, or by means of mechanical structure drive.

As an optional implementation mode, the multi-part synchronous assembling clamp further comprises

The turnover plate is used for receiving external force, the turnover plate is provided with turnover piles corresponding to the first clearance holes or the second clearance holes, and the turnover piles are used for applying pressure to the parts, exposed out of the first clearance holes or the second clearance holes, of the first component to enable the first component to be fixedly assembled in a torsion mode relative to the second component.

For the fixture for completing the torsional assembly and fixation of multiple groups of parts at a time, the addition of the turnover plate with the turnover piles can undoubtedly bring about the further great improvement of the assembly efficiency. Importantly, the special turnover plate is beneficial to accurately controlling the torsion angle of the part, and the stability of the assembly quality is further improved; the control of the torsion angle can be achieved by controlling the length of the upended pile or the shape of its free end (including the tilt state). Meanwhile, the turnover plate also provides possibility for realizing the automation of synchronous assembly of multiple parts.

As an optional implementation manner, the pressing plate is detachably connected with the positioning plate. After all parts to be assembled are placed into the positioning plate, the pressing plate covers the opening of the positioning plate and is connected with the opening of the positioning plate, then the parts are moved to one side of the turnover plate with the turnover piles as a whole, the turnover plate, the positioning plate and the pressing plate as a whole move in the opposite direction, and the turnover piles are inserted from the first clearance holes/the second clearance holes to enable the parts to be twisted to complete assembly and fixation. For the embodiment, the detachably connected pressure plate and the positioning plate are integrated with the parts positioned in the pressure plate and the positioning plate, and can be freely moved or turned without worrying about the displacement of the parts, and the turning plate can also apply force to the parts in the horizontal direction, so that the arrangement direction of the turning plate is not limited. However, assembly work is usually performed in a flow line manner, the positioning work is usually longer than twisting work, and especially when the twisting process is driven in a mechanical manner, it is prudent to dispose positioning plates whose number is significantly more than that of the turnover plates, and at this time, a factory is required to dispose a corresponding number of pressing plates, which results in higher equipment cost.

In order to overcome the defects of the above embodiment, as another alternative embodiment, the pressing plate is connected to one side of the turnover plate, which is provided with the turnover piles, through a compressible elastic connecting piece; when the compressible elastic connecting piece is in an extended state, the overturning piles are completely positioned between the overturning plate and the pressing plate; and when the compressible elastic connecting piece is in a compressed state, the overturning pile penetrates through the second clearance hole. At the moment, the positioning plate filled with the parts to be assembled is moved to the position below the pressing plate, the turnover plate connected with the pressing plate moves downwards to cover and press the pressing plate on the positioning plate, the parts in the positioning plate are completely positioned by the pressing plate and the positioning plate, then the turnover plate continues to press downwards, the pressing plate abutting against the opening of the positioning plate stops moving downwards, the turnover plate continues to press downwards due to the inherent property of the compressible elastic connecting piece, and the turnover pile penetrates through the second avoidance hole of the pressing plate in a straight-inserting mode to enable the first part exposed in the turnover plate to be twisted downwards to complete assembly. In the flow process, only the pressing plates with the quantity equivalent to that of the turnover plates and the positioning plates with the quantity larger than that of the turnover plates are needed to be configured, so that the equipment cost is greatly reduced. In the positioning process, an operator only needs to position the part to be assembled on the positioning plate according to the preassembly relation, and half-positioning operation is completed, so that the operation flow is greatly reduced, and the assembly efficiency is further improved.

As an optional implementation manner, the compressible elastic connecting part comprises a compression spring with strong rigidity, the compression spring is prevented from being stressed and bent in the process that the turnover plate is close to the pressing plate to a certain extent, but the higher the rigidity is, the difficulty of compression is correspondingly increased, in order to overcome the contradiction problem, the connection relationship between the turnover plate and the pressing plate is further optimized, and the accuracy that the turnover pile successively penetrates through the pressing plate and the positioning plate is improved

One end of the pull rod is fixedly connected with the pressing plate/the turnover plate, and the other end of the pull rod is movably connected with the turnover plate/the pressing plate; and

and the compression spring is sleeved on the pull rod between the pressing plate and the turnover plate.

The torsional process need provide the space for the torsion of first part, when assembly jig includes the returning face plate that possesses the upset stake, only need with the returning face plate fixed and make the one side that is equipped with the upset stake up or outwards, thereby can artificially let locating plate and the clamp plate of interconnect and wherein fill with the part be close to the returning face plate and make first clearance hole and/or second clearance hole cover advance the upset stake and accomplish and twist reverse the assembly, need not come to create the space for the torsion process through other devices or structure. However, this method is difficult to mechanize, and as an alternative embodiment, the multi-part synchronous assembling jig further comprises

And the fixing plate is provided with a supporting pile for supporting the positioning plate or the pressing plate so as to provide a space for the first part to twist.

The fixing plate provided with the supporting piles provides a space for the torsion of the first component positioned between the positioning plate and the pressing plate, the torsion of the first component can be smoothly realized no matter manual pressing or mechanical pressing is adopted, the selection of the pressing direction and the active approach direction between the turnover plate and the positioning plate/the pressing plate is not limited, the possibility is provided for realizing mechanization, and particularly under the condition that the pressing plate is connected with the turnover plate, and the pressing direction must be from top to bottom.

The first part with the second part needs to be twisted relative to the second part to achieve complete assembly, which reflects from some sides that the part of the first part contacting the second part is probably not a cylinder like the feeding sheet, but is angular, if the freedom of the second part is completely limited by the cooperating positioning plate and pressing plate, the subsequent pressing and twisting are not facilitated, and even forced twisting may cause the feeding sheet to be damaged; the second component is not completely limited, so that the first component and even the second component are difficult to be stably positioned due to the fact that the first component is easy to overturn due to self weight when the first component is placed into the positioning plate.

In order to overcome the above technical problem, as an optional implementation manner, a clamping position for avoiding an external force or turning the pile is arranged in the first clearance hole, and the clamping position is used for temporarily limiting the torsional freedom degree of the first component when the first component is placed into the positioning plate, so that the second component cannot be stably positioned due to the fact that the first component is turned over due to self weight.

As another optional implementation mode, the multi-part synchronous assembling clamp further comprises

The supporting plate is lined at the opposite side of the positioning plate provided with the part positioning groove, and a supporting block which is used for penetrating the positioning plate before applying pressure to assist in positioning the first part is arranged on the supporting plate.

The above embodiment also can temporarily limit the degree of freedom of torsion of the first member when the first member is placed in the positioning plate, so as to prevent the second member from being unstable in positioning due to the overturning of the first member due to its own weight. Compare in first embodiment, the mould design and the processing degree of difficulty of locating plate are obviously lower among this embodiment, are favorable to reducing equipment cost.

In order to prevent the support plate and the positioning plate from going out of position during positioning operation, the support plate is detachably connected with the positioning plate as a preferred embodiment. The backup pad is connected fixedly with the locating plate in the location operation process, and the backup pad is taken down from the locating plate after the clamp plate compresses tightly the locating plate in order to avoid the backup pad to form the interference to twisting.

More preferably, the support plate is magnetically connected with the positioning plate. Compare in other forms such as joint can dismantle the connection, magnetism is connected with and does benefit to more conveniently to be connected to the locating plate with the backup pad on or lift the backup pad off from the locating plate, and magnetism is connected the realization mode can be that the dorsal part that is equipped with the part constant head tank at the locating plate and the backup pad be equipped with one side installation magnet of supporting shoe, and this magnet can be ordinary magnet also can be the electro-magnet.

To the implementation mode of increasing the backup pad, when the twist is implemented by the returning face plate that even has the clamp plate, the locating plate that will fix a position the part removes the in-process below the clamp plate, for preventing the upset of first part, will break away from the part constant head tank together with the second part even, need let the backup pad accompany the locating plate and remove the backup pad below the clamp plate together, until the clamp plate seals the locating plate. When the support plate is connected with the positioning plate in a magnetic connection mode of the electromagnet, the control circuit can control the magnetic force of the electromagnet to disappear so as to remove the support plate. When the supporting plate is connected with the positioning plate in a common magnet magnetic connection or other detachable connection mode, external force needs to be applied in the process of removing the supporting plate, as an optional implementation mode, a push rod is arranged on the turnover plate for receiving the external force, and the push rod is used for penetrating through the pressing plate and the positioning plate to jack off the supporting plate before the turnover pile applies pressure to the first component.

As an alternative embodiment, the multi-part synchronous assembling jig further comprises a support plate which can be moved back in a falling manner when the support plate is disconnected from the positioning plate

The buffer cushion is positioned below the supporting plate and used for buffering and receiving the supporting plate when the supporting plate is disconnected with the positioning plate (namely the supporting plate is separated from the positioning plate), so that the supporting plate or parts below the supporting plate are prevented from being damaged due to impact.

The invention provides a synchronous automatic assembling device for multiple parts in a third aspect, which comprises

The assembling fixture is a multi-part synchronous assembling fixture comprising a turnover plate, a pressing plate and a positioning plate, which is provided by the second aspect of the invention; and

a crimper including a drive mechanism for driving the flipping plate.

The invention realizes synchronous automatic assembly of multiple parts by combining the multiple part synchronous assembly fixture and the crimping machine, realizes mechanization of torsional assembly, improves assembly efficiency, is beneficial to improvement and stability of assembly quality, and lays a foundation for smooth antenna assembly of subsequent antenna assembly quality improvement.

In the above embodiment, the driving mechanism applies an acting force for twisting the first component by driving the turnover plate, and when the driving mechanism only provides an acting force for twisting and the turnover plate is not connected with other mechanisms such as a pressing plate, the turnover plate can be ensured to move stably in a certain direction, however, when the turnover plate is connected with a pressing plate or even a top rod and the driving mechanism needs to apply pressure to more mechanisms including a positioning plate or even a supporting plate, the difficulty of ensuring that the turnover plate and the pressing plate connected thereto move in a certain direction all the time is increased to some extent

The driving mechanism is connected with the turnover plate through the movable plate; and

and two ends of the guide post are respectively connected to two opposite sides of the crimping machine, and the movable plate is connected with the guide post in a sliding manner.

The turnover plate is connected with the movable plate through the movable plate, and the motion trail of the movable plate is limited through the guide pillar, so that the motion trail of the turnover plate is accurately controlled, the turnover piles or the ejector rods arranged on the turnover plates can accurately penetrate through the pressing plate and the positioning plate, the running reliability of equipment is improved, and the service life of the equipment is prolonged.

For the embodiment that the assembly fixture comprises the supporting plate, the ejector rod used for ejecting the supporting plate before the first component is pressed is arranged on the turnover plate or the movable plate, when the turnover plate is fixedly connected with the movable plate, the ejector rod penetrates through the turnover plate, and after being driven by the driving mechanism, the ejector rod continuously penetrates through the pressing plate and the positioning plate to eject the supporting plate before the turnover pile presses the first component.

Compared with the prior art, the invention has the beneficial effects that:

1. the labor intensity of operators is reduced, and manual assembly is changed into pneumatic control automatic assembly of the feed sheet assembly;

2. in the assembling process, the positioning guide structure is adopted for accurate positioning, so that the stability and consistency of the assembling quality of the feed sheet assembly are ensured, and the overall assembling quality of the vibrator is improved;

Detailed Description

The drawings are only for purposes of illustration and are not to be construed as limiting the invention. For the purpose of better illustrating the following embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

Example 1

As shown in fig. 2, the present embodiment provides a method for assembling multiple parts simultaneously, which is used for positioning and assembling at least one first component and at least one second component, and includes the following steps:

The embodiment creatively provides the technical problems of complex assembly, low assembly efficiency, unstable assembly quality and high assembly cost of small-volume parts by adopting the clamp to finish the torsion assembly fixation between more than two parts. The method comprises the steps of firstly pre-assembling and positioning parts to be assembled through a clamp, then pressing one of two parts with a twisting relationship in an assembling process through a clearance on the clamp to twist relative to the other part, establishing a correct assembling relationship between the two parts as a result of twisting, entering a complete assembling state, determining a twisting angle alpha according to a relative position relationship between the pre-assembling state and the complete assembling state of the two parts, and generally taking alpha e (0, 90 degrees).

Where multiple parts refer to one or more groups of parts, each group of parts comprising at least one first part and at least one second part, for example, fig. 1 shows a feed tab 3 assembly for a die-cast vibrator, which comprises one first part (feed tab 3) and two second parts (dielectric block 1 and dielectric block 2). When the fixture can complete the assembly and fixation of multiple groups of parts at one time, the assembly efficiency is improved by times, which is the aim of the embodiment, and the fixture can be correspondingly adjusted into one group for the conditions that the fixture is complex and cannot complete the assembly of multiple groups of parts at one time.

The first component is like a feed sheet 3 in a feed sheet 3 assembly and is provided with a connecting part used for being connected with the second component and a stressed part which relatively protrudes out of the connecting part and is used as a pressure application acting point, and the stressed part just faces to a clearance on the clamp when the first component is positioned on the clamp; the second part is like a dielectric block in the feed sheet 3 assembly and is sleeved on the connecting part of the first part during and after assembly.

Example 2

As shown in fig. 3, this embodiment provides a multi-part synchronous assembling jig applying the method described in embodiment 1, for positioning and assembling at least one first part and at least one second part, and includes a positioning plate 300 and a pressing plate 200, where the positioning plate 300 is provided with a part positioning slot 320 and a first clearance hole 310, the part positioning slot 320 is used for positioning the first part and the second part that are pre-fitted to each other, and the first clearance hole 310 is used for partially exposing the first part; the pressing plate 200 covers the positioning plate 300, a second clearance hole 210 corresponding to the first clearance hole 310 is formed in the pressing plate 200, and the second clearance hole 210 is used for partially exposing the first component; the external force presses the portion of the first component exposed to the clearance hole through the first clearance hole 310 or the second clearance hole 210, so that the first component is fixed in a torsional assembly with respect to the second component.

In the embodiment, the positioning plate 300 and the pressing plate 200 are matched to complete the pre-assembly and positioning of the parts, and part of one of the two components having a twisting relationship is exposed to the first clearance hole 310 and the second clearance hole 210, and then the exposed part is pressed from the first clearance hole 310 to be twisted or to penetrate through the second clearance hole 210, or the exposed part is pressed from the second clearance hole 210 to be twisted or to penetrate through the first clearance hole 310 by virtue of external force, so as to complete the twisting assembly positioning. Whether the member to be pressed passes through the first clearance hole 310 or the second clearance hole 210 during or after the pressing depends on the angle of the torsion and the size of the part or the jig; the angle of twist is dependent on the relative positional relationship between the two components from the pre-assembled state to the fully assembled state, typically in the range of α e (0, 90 °). The external force may be applied by manually poking the exposed parts from the first clearance hole 310 or the second clearance hole 210 to the second clearance hole 210 or the first clearance hole 310 side one by one, or by driving the pressure by means of a mechanical structure.

Optionally, a part positioning protrusion 220 corresponding to the part positioning groove 320 is disposed on the pressing plate 200. For example, as shown in fig. 4, the first component is a feeding sheet 3, the second component is a dielectric block 1 and a dielectric block 2, both of the two dielectric blocks have a notch, when the two dielectric blocks are positioned in the part positioning groove 320, the notch faces the pressing plate 200, correspondingly, a part positioning protrusion 220 is arranged at a contact position of the pressing plate 200 and the notch of the dielectric block, the part positioning protrusion 220 limits the feeding sheet 3 in a certain range and cannot move easily, pressing surfaces corresponding to the dielectric block 1 and the dielectric block 2 are respectively arranged on the pressing plate 200 to ensure the pressing of the dielectric block 1 and the dielectric block 2, and corresponding surfaces corresponding to different parts of the feeding sheet 3 are also arranged to limit the feeding sheet 3 in a certain range and ensure that the feeding sheet is not interfered during turning.

Example 3

As a preferred implementation manner of embodiment 2, the present embodiment is different from embodiment 2 in that, as shown in fig. 5, the multi-part synchronous assembling jig further includes an overturning plate 100, the overturning plate 100 is configured to receive an external force, an overturning pile 110 corresponding to the first clearance hole 310 or the second clearance hole 210 is disposed on the overturning plate 100, and the overturning pile 110 is configured to press a portion of the first component exposed to the first clearance hole 310 or the second clearance hole 210 so as to be assembled and fixed in a twisting manner with respect to the second component. Optionally, the turning piles 110 are positioned and fixed to the turning plate 100 by means of turning pile 110 positioning slots provided on the turning plate 100.

For the fixture which completes the torsional assembly and fixation of a plurality of groups of parts at one time, the addition of the turnover plate 100 with the turnover piles 110 can undoubtedly bring about further great improvement of the assembly efficiency. Importantly, the special turnover plate 100 is beneficial to accurately controlling the torsion angle of the part, and the stability of the assembly quality is further improved; the control of the torsion angle can be achieved by controlling the length of the turn-over stub 110 or the shape of the free end thereof (including the tilt state), for example, the contact surface of the turn-over stub 110 with the feed tab 3 (i.e., the free end of the turn-over stub 110) can be a plane surface, as shown in fig. 9; the design may be an inclined plane according to the actual design, as shown in fig. 10, on one hand, the torsion angle of the feeding sheet 3 can be controlled, and on the other hand, the torsion action can be made smooth. At the same time, the presence of the flipping panel 100 also provides the possibility to automate the simultaneous assembly of multiple parts.

Optionally, the pressing plate 200 is detachably connected to the positioning plate 300. After all the parts to be assembled are placed in the positioning plate 300, the pressing plate 200 covers and is connected with the opening of the positioning plate 300, then the whole is moved to one side of the turnover plate 100 provided with the turnover piles 110, the turnover plate 100, the positioning plate 300 and the pressing plate 200 as a whole move in the opposite direction, and the turnover piles 110 are inserted from the first clearance holes 310/the second clearance holes 210 so that the parts are twisted to complete assembly and fixation. For this embodiment, the detachably connected pressing plate 200 and the positioning plate 300, together with the components positioned therein, are an integral body, and can be freely moved or turned without worrying about the displacement of the components therein, and the turning plate 100 can also apply force to the components therein in the horizontal direction, without limitation to the placing direction of the turning plate 100. However, assembly work is usually performed by a pipeline operation, while the positioning work is usually longer than twisting work, especially when the twisting process is driven by a mechanical method, it is not prudent that the positioning plates 300 are configured in a number significantly greater than that of the flipping plates 100, and a factory is required to configure a corresponding number of pressing plates 200, which results in higher equipment cost.

Example 4

As a preferred embodiment of embodiment 3, this embodiment is different from embodiment 3 in that, as an alternative to detachably connecting the pressure plate 200 with the positioning plate 300, as shown in fig. 6, the pressure plate 200 is connected to the side of the roll-over plate 100 provided with the roll-over piles 110 through a compressible elastic connector; with the compressible elastomeric connectors in an extended state, the inverting studs 110 are located entirely between the inverting plate 100 and the platen 200; in the compressed state of the compressible elastic connector, the turning pile 110 passes through the second clearance hole 210. At this time, the positioning plate 300 filled with the parts to be assembled is moved to the lower part of the pressing plate 200, the turnover plate 100 connected with the pressing plate 200 moves downwards to cover and press the pressing plate 200 on the positioning plate 300, the parts in the positioning plate 200 and the positioning plate 300 are completely positioned, then the turnover plate 100 continues to press downwards, the pressing plate 200 abutting against the opening of the positioning plate 300 stops moving downwards, the turnover plate 100 continues to press downwards due to the inherent property of the compressible elastic connecting piece, and the turnover pile 110 penetrates through the pressing plate 200 to be directly inserted into the second avoidance hole, so that the first part exposed in the turnover plate 200 is twisted downwards to complete the assembly. In the flow process, only the pressing plates 200 with the number equivalent to that of the turnover plates 100 and the positioning plates 300 with the number larger than that of the turnover plates 100 are needed to be configured, so that the equipment cost is greatly reduced. In the positioning process, an operator only needs to position the part to be assembled on the positioning plate 300 according to the preassembly relation, and half positioning operation is completed, so that the operation flow is greatly reduced, and the assembly efficiency is further improved.

Preferably, the compressible elastic connecting member may adopt a compression spring 121 with stronger rigidity, although the compression spring 121 is prevented from being stressed and bent when the roll-over plate 100 approaches the press plate 200 to a certain extent, the greater the rigidity is, the greater the difficulty of compression is correspondingly increased, in order to overcome the contradiction problem, the connection relationship between the roll-over plate 100 and the press plate 200 is further optimized, and the accuracy of the roll-over pile 110 passing through the press plate 200 and the positioning plate 300 in succession is improved, as an optional implementation manner, the compressible elastic connecting member includes a pull rod 122 and a compression spring 121, one end of the pull rod 122 is fixedly connected with the press plate 200, and the other end is movably connected with the roll-over plate 100; optionally, one end fixedly connected with the pressure plate 200 is provided with a thread structure, and the thread structure is in threaded connection with the pressure plate 200; one end movably connected with the turnover plate 100 is provided with a step structure which is movably matched with a step hole arranged on the turnover plate 100.

The compression spring 121 is sleeved on the pull rod 122 between the pressing plate 200 and the turnover plate 100; the flipping panel 100 and the pressing panel 200 are spaced apart by a distance by the compression spring 121. Optionally, a compression spring 121 is also arranged at a position where the pull rod 122 is not arranged, so as to improve the uniformity of the acting force of the turnover plate 100 on the press plate 200; alternatively, a plurality of spring guide rods 123 are provided at positions where the compression springs 121 are not fitted over the tension rods 122 for guiding the compression springs 121, as shown in fig. 6, and the spring guide rods 123 are fixed to the flipping panel 100, it is understood that the spring guide rods 123 may be fixed to the pressing panel 200. After assembly, the pressure applied to the roll-over panel 100 is removed and the press panel 200 and the roll-over panel 100 return to their original relative positions by the compressible elastomeric connectors.

Example 5

The process of twisting needs to provide a space for the twisting of the first component, when the assembly fixture comprises the turnover plate 100 with the turnover piles 110, the positioning plate 300 and the pressing plate 200 which are connected with each other and are filled with parts can be manually close to the turnover plate 100 and the first clearance holes 310 and/or the second clearance holes 210 are sleeved in the turnover piles 110 to complete the twisting assembly only by fixing the turnover plate 100 and enabling the surface provided with the turnover piles 110 to face upwards or outwards, and no space needs to be created for the twisting process through other devices or structures. However, mechanization is difficult to achieve in this manner, and as a preferred embodiment of embodiments 2 to 4, this embodiment is different from embodiments 2 to 4 in that, as shown in fig. 7, the multi-part synchronous assembling jig further includes a fixing plate 500, and a supporting pile 510 for supporting the positioning plate 300 or the pressing plate 200 is provided on the fixing plate 500 to provide a space for twisting the first component. Optionally, a positioning hole of the support peg 510 is formed on the fixing plate 500, the support peg 510 is positioned by the positioning hole of the support peg 510, and an end surface of the support peg 510 contacts with a backside of the positioning plate 300 having the component positioning groove 320, so that the fixing plate 500 and the positioning plate 300 are spaced apart by a distance to form a space for the feed tab 3 to twist. Optionally, a plurality of fixing plates 500 are processed on the fixing plate

Example 6

The first part with the second part needs to be twisted relative to the second part to achieve complete assembly, which reflects from some sides that the part of the first part contacting the second part is probably not a cylinder like the feeding piece 3, but angular, and if the freedom of the second part is completely limited by the cooperating positioning plate 300 and pressing plate 200, the subsequent forced twisting is not favorable, even if the forced twisting may cause the feeding piece 3 to be damaged; the second member is not completely limited, so that the first member and even the second member are difficult to be stably positioned due to the easy overturning of the first member due to the self weight of the first member when the first member is inserted into the positioning plate 300.

In order to overcome the above technical problems, as a preferred embodiment of embodiments 3 to 5, this embodiment is different from embodiments 3 to 5 in that, as shown in fig. 8, the multiple component synchronous assembling jig further includes a supporting plate 400, the supporting plate 400 is lined on the opposite side of the positioning plate 300 where the component positioning groove 320 is provided, and the supporting plate 400 is provided with a supporting block 410 for passing through the positioning plate 300 before pressing to assist in positioning the first component. Alternatively, the supporting plate 400 is formed with positioning grooves for positioning the positioning plate 300, and the supporting plate 400 is formed with a plurality of positioning grooves for fixing the supporting blocks 410.

The support plate 400 can temporarily limit the torsional degree of freedom of the first member when the first member is inserted into the positioning plate 300, so as to prevent the second member from being unstably positioned due to the overturn of the first member caused by the self weight of the first member. It is understood that other embodiments may be adopted for temporarily limiting the degree of freedom of the first component, for example, a detent is provided in the first clearance hole 310 to avoid an external force or to turn the pile 110, and the detent may also be used for temporarily limiting the degree of freedom of the first component when the first component is inserted into the positioning plate 300, so as to prevent the second component from being unstable due to the turning of the first component caused by its own weight. In contrast, the positioning plate 300 of the embodiment with the additional supporting plate 400 has a lower difficulty in mold design and processing, which is beneficial to reduce the equipment cost.

The support plate 400 is used to temporarily assist in supporting and limiting the degree of freedom of the first member when placing a component into the alignment plate 300, and is not associated with the alignment plate 300, and in order to prevent the support plate 400 from being out of position with the alignment plate 300 when performing an alignment operation, as a preferred embodiment, the support plate 400 is detachably connected to the alignment plate 300. The supporting plate 400 is fixedly connected with the positioning plate 300 in the positioning process, and the supporting plate 400 is removed from the positioning plate 300 after the pressing plate 200 presses the positioning plate 300 so as to prevent the supporting plate 400 from interfering with the twisting.

More preferably, the support plate 400 is magnetically coupled to the positioning plate 300. Compared with other detachable connections such as clamping connection, the magnetic connection is beneficial to more conveniently connecting the supporting plate 400 to the positioning plate 300 or detaching the supporting plate 400 from the positioning plate 300, the magnetic connection can be realized by installing a magnet 420 on the back side of the positioning plate 300 provided with the part positioning slot 320 and the side of the supporting plate 400 provided with the supporting block 410, and the magnet 420 can be a common magnet 420 or an electromagnet 420. Alternatively, a plurality of magnet 420 positioning holes for the positioning magnets 420 are formed in the supporting plate 400, and a plurality of corresponding magnet 420 positioning holes for the positioning magnets 420 are formed in corresponding positions of the positioning plate 300, so that the magnets 420 are fixed to the supporting plate 400 and the positioning plate 300, respectively, so that the two plates are adhered to each other by magnetic force when the supporting plate 400 and the positioning plate 300 are combined.

When the rotation is performed by the flipping board 100 connected to the pressing board 200, in the process of moving the positioning board 300 with the parts positioned to the lower side of the pressing board 200, in order to prevent the first part from flipping, even the second part will be separated from the parts positioning groove 320, the supporting board 400 needs to be moved to the lower side of the pressing board 200 together with the positioning board 300 until the pressing board 200 seals the positioning board 300, and the supporting board 400 can be removed. When the supporting plate 400 is connected to the positioning plate 300 in such a manner that the electromagnet 420 is magnetically connected, the supporting plate 400 can be removed by controlling the magnetic force of the electromagnet 420 to disappear by the control circuit. When the supporting plate 400 is magnetically connected or detachably connected to the positioning plate 300 by the common magnet 420, an external force is applied during the process of removing the supporting plate 400, and optionally, a top bar 621 is disposed on the flipping plate 100 for receiving the external force, wherein the top bar 621 is used for passing through the pressing plate 200 and the positioning plate 300 to lift off the supporting plate 400 before the flipping pile 110 applies pressure to the first component.

The supporting plate 400 can be withdrawn in a dropping manner when the supporting plate is disconnected from the positioning plate 300, and at this time, the multi-part synchronous assembling jig further comprises a cushion 520, wherein the cushion 520 is located below the supporting plate 400 and is used for buffering and receiving the supporting plate 400 when the supporting plate 400 is disconnected from the positioning plate 300, so that the impact of the falling of the supporting plate 400 after the supporting plate 400 is separated from the positioning plate 300 is buffered, and the supporting plate 400 or the components below the supporting plate 400 are prevented from being deformed and damaged due to the impact. Optionally, in combination with embodiment 5, a plurality of hole positions are formed on the cushion 520 to avoid the support piles 510 and the screw mounting hole positions for fixing on the fixing plate 500; a plurality of escape notches 530 are also formed at the fixing plate 500 and the cushion 520 to facilitate the removal of the support plate 400 which is detached from the alignment plate 300 and falls down.
