Description

Technical Field

[0001] This utility model relates to the field of handwheel spoke technology, and specifically to a processing device for producing handwheel spokes. Background Technology

[0002] The spokes of a handcart wheel are a component responsible for connecting the tire and axle, supporting and transmitting the load. Handcart wheel spokes are typically made of metal, with steel and aluminum being common materials. During production, the spokes require grinding. However, existing methods often involve placing the spokes on a workbench surface before grinding, lacking a mechanism to secure them. This leads to easy misalignment during grinding and generates significant amounts of dust, which, if not properly managed, can be inhaled by workers, causing injury.

[0003] A search revealed that CN220971718U discloses a grinding device with a dustproof structure, including a worktable and a grinding machine. The surface of the worktable is provided with a clamping mechanism and a dustproof structure. The clamping mechanism includes a fixed plate. Two fixed plates are fixedly connected to the two end surfaces of the worktable. A bidirectional threaded rod passes through the surface of the fixed plate and is rotatably connected to the fixed plate. A slider passes through the surface of the bidirectional threaded rod and is threadedly connected to the bidirectional threaded rod. A connecting plate is fixedly connected to the top surface of the slider. This dustproof grinding device uses a throttle to rotate a bidirectional threaded rod. As the rod rotates, two sliders on its surface move closer to the center. These sliders, through a connecting plate, drive a clamping plate to slide towards the center, fixing the wheel spokes. This improves spoke fixation, resulting in better grinding, more accurate data, and reduced errors. However, its drawback is that while the device can fix the spokes, the contact area between the flat clamping plate and the spokes is small. When force is applied to the spokes, they may shift, affecting the processing. Therefore, improving existing processing devices and designing a new type of hand-operated wheel spoke production processing device to address these technical shortcomings and enhance the overall practicality of the processing device is crucial. Utility Model Content

[0004] The purpose of this utility model is to provide a processing device for producing wheel spokes of a hand-operated wheel. Through the design of multiple sets of bonding blocks, multiple surfaces of the wheel spokes can be limited, increasing the contact area with the wheel spokes and preventing the wheel spokes from shifting during processing, which would affect the processing effect, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A processing device for producing wheel spokes of a hand-operated wheel includes a workbench body, a connecting frame fixedly connected to the top of the workbench body, a grinding disc provided inside the connecting frame, a connecting frame fixedly connected to the top of the workbench body and located inside the connecting frame, and a limiting component provided at the top of the connecting frame.

[0007] The limiting component is used to stably clamp the wheel spokes. The limiting component consists of a connecting plate, multiple sets of moving rods, multiple sets of fixed rods, multiple sets of moving blocks, and multiple sets of fitting blocks. The connecting plate is located inside the connecting frame. The multiple sets of moving rods are slidably connected to the outside of the connecting plate. The fixed rod is fixedly connected to the end of the moving rod away from the connecting plate and extends to the top of the connecting frame. The moving block is fixedly connected to the top of the fixed rod. The fitting block is slidably connected to the inside of the moving block.

[0008] As a preferred embodiment of this utility model, a gear disk is rotatably connected to the bottom of the connecting disk, and multiple sets of arc-shaped grooves are formed inside the gear disk, with the moving rod slidingly connected to the arc-shaped grooves.

[0009] As a preferred embodiment of this utility model, a drive gear is meshed with the outer side of the gear disk, a worm gear is fixedly connected to the bottom of the drive gear, a worm is meshed with the outer side of the worm gear, and the drive end of the drive motor is fixedly connected to the outer side of the worm.

[0010] As a preferred embodiment of this utility model, a sliding groove is provided at the top of the connecting frame and on the outside of the moving rod, the moving rod and the sliding groove are slidably connected, and a waste hopper is fixedly connected to the center of the connecting frame.

[0011] As a preferred embodiment of this utility model, a waste pipe is rotatably connected to the center of the gear disk, the waste pipe is fixedly connected to the waste hopper, and the end of the waste pipe away from the waste hopper extends into the interior of the workbench body.

[0012] As a preferred embodiment of this utility model, two sets of rotating blocks are fixedly connected to one end of the bonding block near the moving block, and rotating rods are rotatably connected to both sides of the rotating block away from the bonding block. A sliding block is fixedly connected to one end of the rotating rod away from the rotating block.

[0013] As a preferred embodiment of this utility model, the two sets of sliding blocks are connected by sliding rods, the sliding blocks and sliding rods are slidably connected, the sliding rods are fixedly connected inside the moving block, and compression springs are sleeved on both sides of the sliding rods and on the outside of the two sets of sliding blocks.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the design of the limiting component allows multiple sets of bonding blocks to contact the wheel spokes. A compression spring drives the sliding block to move, causing the rotating rod to move, which in turn drives the rotating block to move, thus causing the bonding blocks to move and adhere to the surface of the wheel spokes. This allows the wheel spokes to be limited. The design of multiple sets of bonding blocks allows for limiting multiple surfaces of the wheel spokes, increasing the contact area with the wheel spokes and preventing the wheel spokes from shifting during processing, which would affect the processing effect.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] A processing device for producing wheel spokes of a hand-operated wheel includes a workbench body 1, a connecting frame 2 fixedly connected to the top of the workbench body 1, a grinding disc 3 provided inside the connecting frame 2, a connecting frame 4 fixedly connected to the top of the workbench body 1 and located inside the connecting frame 2, and a limiting component 5 provided on the top of the connecting frame 4.

[0025] The limiting component 5 is used to stabilize and clamp the wheel spokes. The limiting component 5 consists of a connecting plate 6, multiple sets of moving rods 7, multiple sets of fixing rods 8, multiple sets of moving blocks 9, and multiple sets of bonding blocks 10. The connecting plate 6 is located inside the connecting frame 4. The multiple sets of moving rods 7 are all slidably connected to the outside of the connecting plate 6. The fixing rods 8 are fixedly connected to the end of the moving rods 7 away from the connecting plate 6 and extend to the top of the connecting frame 4. The moving blocks 9 are fixedly connected to the top of the fixing rods 8. The bonding blocks 10 are slidably connected to the inside of the moving blocks 9.

[0026] Furthermore, a gear disk 11 is rotatably connected to the bottom of the connecting disk 6. The gear disk 11 has multiple sets of arc-shaped grooves 12 inside. The moving rod 7 is slidably connected to the arc-shaped grooves 12. When the gear disk 11 rotates, it drives the multiple sets of arc-shaped grooves 12 to move, which in turn drives the moving rod 7 to move, thereby driving the fixed rod 8 to move. When the fixed rod 8 moves, it drives the moving block 9 to move, which in turn drives the contact block 10 to move and contact the spokes.

[0027] The gear disk 11 is connected to a drive gear 13 on its outer side. A worm gear 14 is fixedly connected to the bottom of the drive gear 13. A worm 15 is connected to the outer side of the worm gear 14. The drive end of the drive motor is fixedly connected to the outer side of the worm 15. When the drive motor is started, the worm 15 is rotated, which in turn rotates the worm gear 14, causing the drive gear 13 to rotate, and thus the gear disk 11 to rotate. When the bonding block 10 is moved to the designated position, the self-locking property of the worm 15 and worm gear 14, in conjunction with the drive motor, enables the bonding block 10 to be limited, preventing the bonding block 10 from shifting.

[0028] Secondly, a sliding groove 16 is provided at the top of the connecting frame 4 and on the outside of the moving rod 7. The moving rod 7 and the sliding groove 16 are slidably connected. A waste hopper 17 is fixedly connected at the center of the connecting frame 4. The moving rod 7 and the sliding groove 16 are slidably connected. When the moving rod 7 moves, it is guided by the sliding groove 16 to prevent the moving rod 7 from deviating.

[0029] Furthermore, a waste pipe 18 is rotatably connected to the center of the gear disk 11. The waste pipe 18 is fixedly connected to the waste hopper 17. The end of the waste pipe 18 away from the waste hopper 17 extends into the interior of the workbench body 1. When the spokes are being polished, the waste generated during polishing falls into the interior of the waste hopper 17, which is then introduced into the interior of the waste pipe 18 to collect the waste.

[0030] Furthermore, two sets of rotating blocks 19 are fixedly connected to one end of the bonding block 10 near the moving block 9. Rotating rods 20 are rotatably connected to both sides of the rotating block 19 away from the bonding block 10. Sliding blocks 21 are fixedly connected to the end of the rotating rod 20 away from the rotating block 19. The two sets of sliding blocks 21 are connected by sliding rods 22. The sliding blocks 21 and sliding rods 22 are slidably connected. The sliding rods 22 are fixedly connected inside the moving block 9. Compression springs 23 are sleeved on both sides of the sliding rods 22 and outside the two sets of sliding blocks 21. When the bonding block 10 contacts the spoke, the compression springs 23 drive the sliding blocks 21 to move, causing the rotating rods 20 to move, which in turn drives the rotating blocks 19 to move, thereby causing the bonding block 10 to move and adhere to the surface of the spoke, thus limiting the spoke. Through the design of multiple sets of bonding blocks 10, multiple surfaces of the spoke can be limited, preventing the spoke from shifting during the processing of the spoke and affecting the processing effect.

[0031] In this embodiment, the specific implementation scenario is as follows: In actual use, the wheel spokes are placed on top of the connecting frame 4 and inside the multiple sets of moving blocks 9. The drive motor is started, driving the worm gear 15 to rotate, causing the worm wheel 14 to rotate, which in turn drives the drive gear 13 to rotate, causing the gear disk 11 to rotate. When the gear disk 11 rotates, it causes the multiple sets of arc-shaped grooves 12 to move, which in turn causes the moving rod 7 to move, thereby causing the fixed rod 8 to move. When the fixed rod 8 moves, it causes the moving block 9 to move, causing the contact block 10 to move and contact the wheel spokes. When the bonding block 10 contacts the spoke, the compression spring 23 drives the sliding block 21 to move, causing the rotating rod 20 to move, which in turn drives the rotating block 19 to move, thereby causing the bonding block 10 to move and adhere to the spoke surface. This allows the spoke to be positioned. The design of multiple sets of bonding blocks 10 allows for positioning of multiple surfaces of the spoke, preventing the spoke from shifting during processing and affecting the processing effect. Compared with existing processing devices, this invention improves the overall practicality of the processing device through its design.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
