Technical Field
[0001] The utility model relates to the technical field of spoke processing, in particular to a fixture for automobile spoke processing. Background Technique
[0002] With the development of technology and the progress of society, more and more means of transportation appear in people's daily lives. Means of transportation such as cars, and the performance difference of cars is closely related to the quality of wheels. Spokes are needed in wheels. A spoke is a device for protecting the rim and spokes of a vehicle wheel. Its characteristics are a pair of circular cover plates. The diameter of the cover plate is close to the diameter of the rim. There is a hole in the center of the cover plate that is larger than the vehicle rotation axis. There are orifices in the part of the cover plate close to the edge. The edge of the cover plate has an annular wheel plate. The curved surface of the wheel plate can be closely attached to the curved surface of the rim. According to the structure of the spoke, the wheel is divided into a spoke plate type and a spoke type. Currently, mainstream household cars all adopt the spoke plate type spoke structure. When driving at high speed for a long time, multi-spoke tires are generally used, which can provide good support and prevent large deformation of the wheels during driving.
[0003] Currently, when processing spokes, it is necessary to clamp and fix the spokes. The existing spoke clamping device only clamps bilaterally during clamping and fixing. Since the spoke is circularly arranged, it is easy for the spoke to fall off from the clamping device, and the stability is poor, which is not conducive to the subsequent processing of the spoke. Moreover, most of them are fixed fixtures, and the applicability is poor.
[0004] Therefore, for the improvement of the existing fixture for automobile spoke processing, it is particularly important to design a new fixture for automobile spoke processing to solve the above technical defects and improve the practicability of the overall fixture for automobile spoke processing. Content of the Utility Model
[0005] The purpose of the utility model is to provide a fixture for automobile spoke processing to solve the problems raised in the above background technique.
[0006] To achieve the above purpose, the utility model provides the following technical solutions:
[0007] A fixture for automobile spoke processing includes a base. The left end of the base is fixedly connected with a bracket. The top end inside the bracket is slidably connected with an operating table. A platform is fixedly connected between the base and the bracket. A fixed table is fixedly connected inside the platform. A clamping assembly is installed at the middle of the top of the fixed table;
[0008] The clamping assembly is used for wrapping and clamping spokes of different sizes.
[0009] As a preferred solution of the utility model, the clamping assembly includes a support table, a baffle, a receiving block, a pressing block and a telescopic rod. The support table is fixedly connected to the middle of the fixed table. The baffles are symmetrically and fixedly connected to the periphery of the top of the support table. The receiving block is fixedly connected to the middle of the top of the support table. The pressing block is slidably connected to the top of the support table and is located outside the receiving block. The telescopic rod is fixedly connected between the receiving block and the pressing block.
[0010] As a preferred solution of the utility model, an extension plate is fixedly connected to the top of the pressing block. Anti-slip lines are provided at one end of the pressing block away from the receiving block. A slider is fixedly connected to the bottom of the pressing block. A chute is provided at a position corresponding to the slider on the top of the support table.
[0011] As a preferred solution of the utility model, a slide bar is slidably connected to the inside of the baffle. A rectangular block is fixedly connected to the outside of the slide bar and on the inner side of the baffle. A track is fixedly connected at a position where the rectangular blocks are close to each other. A push plate is slidably connected to the inside of the track.
[0012] As a preferred solution of the utility model, a toothed plate is fixedly connected at a position where the push plates are close to each other. An adapter seat is fixedly connected to one side of the slide bar away from the baffle. A gear is rotatably connected at a position corresponding to the toothed plate inside the adapter seat.
[0013] As a preferred solution of the utility model, a telescopic cylinder is fixedly connected to the top of the fixed table. The output end of the telescopic cylinder is fixedly connected to a mounting plate. A connecting piece is rotatably connected to the bottom of the mounting plate.

A plug shaft is fixedly connected to the middle of the inside of the transfer frame. The transfer frame is rotatably connected to the fixed table through the plug shaft.
[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] In the present utility model, the output end of the telescopic cylinder drives the mounting plate to move, enabling the connecting piece to drive the first swing rod to swing. Under the action of the transfer frame, the second swing rod follows the swing, forming a rhombus between the first swing rod and the second swing rod to squeeze the sliding rod. At the same time, the sliding rod conducts the movement force to the gear, causing the push plate to contact the outside of the extrusion block. When the push plate contacts different positions of the extrusion block, resulting in inconsistent lengths of the two push plates, the gear and the toothed plate mesh with each other, ensuring that the push plate always contacts the extrusion block. Subsequently, the slider will move along with the extrusion block, allowing all the extrusion blocks to move synchronously towards the position of the receiving block. Then, the telescopic rod contracts to completely wrap the wheel spoke. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Embodiment:
[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution:
[0025] A tooling fixture for processing an automobile wheel spoke comprises a base 1, a bracket 2 is fixedly connected to the left end of the base 1, an operating table 3 is slidably connected to the top of the inner side of the bracket 2, a platform 4 is fixedly connected between the base 1 and the bracket 2, a fixed table 5 is fixedly connected inside the platform 4, and a clamping assembly 6 is installed in the middle of the top of the fixed table 5;
[0026] The clamping assembly 6 is used to wrap and clamp spokes of different sizes.
[0027] For further information, see Figure 1 , Figure 2 and Figure 3 In this embodiment, the clamping assembly 6 includes a support platform 601, a baffle 602, a receiving block 603, an extrusion block 604 and a telescopic rod 605. The support platform 601 is fixedly connected to the middle of the fixed platform 5, the baffle 602 is symmetrically fixedly connected to the four sides of the top of the support platform 601, the receiving block 603 is fixedly connected to the middle of the top of the support platform 601, the extrusion block 604 is slidably connected to the top of the support platform 601 and is located outside the receiving block 603, and the telescopic rod 605 is fixedly connected between the receiving block 603 and the extrusion block 604. During the processing of the spoke, it is convenient to operate it. The spoke needs to be fixed. By pushing the extrusion block 604 outward, the telescopic rod 605 will extend outward, so that the spoke is stably placed on the top of the receiving block 603, and then the extrusion block 604 is automatically rebounded by the telescopic rod 605 to restore to its original position, so that the spoke is clamped.
[0028] For further information, see Figure 1 , Figure 2 and Figure 3 In this embodiment, an extension plate is fixedly connected to the top of the extrusion block 604, and an anti-slip groove is provided at one end of the extrusion block 604 away from the receiving block 603. A slider 606 is fixedly connected to the bottom of the extrusion block 604, and a slide groove 607 is provided at the top of the support platform 601 at a position corresponding to the slider 606. The design of the extension plate increases the height of the extrusion block 604, effectively preventing the excess part of the spoke from being unable to be wrapped when the height of the spoke is too high. At the same time, when the extrusion block 604 moves, its slider 606 will follow the movement and be limited by the slide groove 607, so that the slider 606 completes a straight linear motion, keeping all the extrusion blocks 604 moving synchronously.
[0029] For further information, see Figure 1 , Figure 2 , Figure 3 and Figure 4, in this embodiment, a slide bar 7 is slidably connected inside the baffle 602. A rectangular block 8 is fixedly connected to the outside of the slide bar 7 and inside the baffle 602. A track 9 is fixedly connected at a position where the rectangular blocks 8 are close to each other. A push plate 10 is slidably connected inside the track 9. A toothed plate 11 is fixedly connected at a position where the push plates 10 are close to each other. A transfer seat is fixedly connected to one side of the slide bar 7 away from the baffle 602. A gear 12 is rotatably connected inside the transfer seat at a position corresponding to the toothed plate 11. By pressing the slide bar 7, the slide bar 7 will conduct the moving force to the gear 12, and the gear 12 drives the toothed plate 11 to move, so as to realize the contact between the push plate 10 and the outside of the extrusion block 604. When the push plate 10 contacts different positions of the extrusion block 604, the lengths of the two push plates 10 are not unified. Through the meshing of the gear 12 and the toothed plate 11, the push plate 10 is always in contact with the extrusion block 604.
[0030] Further, please refer to Figure 1 and Figure 2 , in this embodiment, a telescopic cylinder 13 is fixedly connected to the top of the fixed table 5. The output end of the telescopic cylinder 13 is fixedly connected with a mounting plate 14. A connecting piece 15 is rotatably connected to the bottom of the mounting plate 14. One end of the connecting piece 15 away from the mounting plate 14 is fixedly connected with a first swing rod 16. A second swing rod 17 is rotatably connected to the outside of the first swing rod 16. A transfer frame 18 is rotatably connected at the connection between the first swing rod 16 and the second swing rod 17. A plug shaft 19 is fixedly connected to the middle of the inside of the transfer frame 18. The transfer frame 18 is rotatably connected to the fixed table 5 through the plug shaft 19. By starting the telescopic cylinder 13, the output end of the telescopic cylinder 13 drives the mounting plate 14 to move, and the connecting piece 15 drives the first swing rod 16 to swing. Under the action of the transfer frame 18, the second swing rod 17 follows the swing, so that a rhombus is formed between the first swing rod 16 and the second swing rod 17.
[0031] In this embodiment, the implementation scenario is specifically as follows: During the process of spoke machining, for the convenience of operation, the spoke is placed on the top of the receiving block 603. By starting the telescopic cylinder 13, the output end of the telescopic cylinder 13 drives the mounting plate 14 to move, and the connecting piece 15 drives the first swing rod 16 to swing. Under the action of the transfer frame 18, the second swing rod 17 follows to swing, forming a rhombus between the first swing rod 16 and the second swing rod 17 and squeezing the slide bar 7. At the same time, the slide bar 7 transmits the movement force to the gear 12, and the gear 12 drives the toothed plate 11 to move, realizing the contact between the push plate 10 and the outer part of the extrusion block 604. When the push plate 10 contacts different positions of the extrusion block 604, the lengths of the two groups of push plates 10 are not unified. Through the meshing of the gear 12 and the toothed plate 11, the push plate 10 is always in contact with the extrusion block 604, and the slider 606 will move accordingly. The slider 606 is limited by the chute 607 to complete a linear motion in a straight line, keeping all the extrusion blocks 604 moving synchronously towards the position of the receiving block 603. Subsequently, the telescopic rod 605 contracts to completely wrap the spoke.
[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
