Description

Technical Field

[0001] This utility model relates to the field of bicycle wheel hub processing technology, and in particular to a conveying and clamping device for processing electric bicycle wheel hubs. Background Technology

[0002] Before grinding the wheel hub, the following steps must be completed in sequence: disassembly and preliminary cleaning, surface defect inspection and dimensional measurement, removal of old coating, damage repair, fine grinding and degreasing and static electricity removal, and masking of non-treated areas. This ensures that the wheel hub surface is free of oil stains, coating peeling and obvious defects, and prepares it for grinding and subsequent surface treatment.

[0003] The hub of an electric bicycle is a cylindrical component installed at the center of the wheel. It mainly consists of a hub motor, hub housing, bearings, and spokes. Its core function is to support the wheel and convert electrical energy into mechanical energy through the hub motor, driving the wheel to rotate. At the same time, it ensures the stability and safety of the wheel rotation. It is a key component of the electric bicycle's transmission system and support structure.

[0004] An electric bicycle wheel hub processing conveying and clamping device is an automated equipment used in the production and processing of electric bicycle wheel hubs. It mainly consists of a conveying mechanism, a positioning mechanism, and a control system. During the conveying process, it can accurately position the wheel hub through mechanical clamping and sensor detection, ensuring accurate positioning of the wheel hub during processing, improving processing accuracy and efficiency, reducing manual intervention, and realizing automated and standardized production of wheel hubs. It is an important piece of equipment for improving the manufacturing quality and production capacity of electric bicycle wheel hubs. However, after long-term operation, the transmission components are prone to wear due to friction, resulting in decreased positioning accuracy or conveying jams. Regular maintenance or replacement of components is required, increasing downtime and maintenance costs. In the existing technology, the transmission system is designed as an independent modular unit, and quick disassembly and assembly are achieved through standardized interfaces. However, traditional devices are only designed for single-size wheel hubs. When producing different specifications, it is necessary to manually change the positioning fixture or adjust the track spacing, which is time-consuming and labor-intensive, affecting the efficiency of production line switching. Utility Model Content

A fan is located on the outer side of the movable block, and the bottom of the movable block is fixedly connected to the other end of the elastic rope.

[0008] Preferably, the outer side of the rotating block is rotatably connected to one side of the bidirectional threaded rod, and a second robotic arm is installed on the rear side of the frame.

[0009] Preferably, the outer side of the bidirectional threaded rod is threaded to the middle of the threaded block, and a limiting rod is provided on the outer side of the frame, the limiting rod being slidably connected to the bottom of the threaded block.

[0010] Preferably, a sliding groove is provided on the outer side of the frame, the sliding groove is opened in the middle of the placement block, and the inner wall of the sliding groove is slidably connected to the moving block.

A horizontal plate is fixed on the threaded block, and a clamping ring is provided on the horizontal plate, thereby realizing the movement of the clamping ring to accommodate different specifications of wheel hub discs for clamping.

[0016] 2. In this utility model, the second starting motor drives the rotating rod to rotate. The rotating rod causes the moving block to move through the connecting rope. The elastic rope on the moving block deforms when it moves. When the tension weakens, it helps the moving block to reset, so that the fan can move and clean the dust and debris on the surface of the wheel hub. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an electric bicycle wheel hub processing, conveying, and clamping device, including a frame 1 and a wheel hub disc 2.

A cleaning mechanism 4 is installed on the left side of the frame 1, which is used to pre-clean the wheel hub discs 2. The clamping mechanism 3 includes two motors 306, which are located on the rear side of the frame 1. The output end of the motors 306 is fixedly connected to a bidirectional threaded rod 301. The kinetic energy of the motors 306 drives the bidirectional threaded rod 301 to rotate. Threaded blocks 302 are provided on both the left and right sides of the outer side. A horizontal plate 305 is fixedly connected to the top of the threaded block 302. A clamping ring 303 is fixedly connected to the outer side of the horizontal plate 305, which will drive the clamping ring 303 to move. A rotating block 304 is provided on the left side of the bidirectional threaded rod 301. The outer side of the rotating block 304 is rotatably connected to one side of the bidirectional threaded rod 301. A mechanical arm 11 is installed on the rear side of the frame 1. The outer side of the bidirectional threaded rod 301 is threadedly connected to the middle of the threaded block 302. A limit rod 5 is provided on the outer side of the frame 1. The limit rod 5 is slidably connected to the bottom of the threaded block 302. The limit rod 5 plays a limiting role.

[0026] Specifically, during the processing of the wheel hub disc 2, the motor 306 is started, using its kinetic energy to drive the bidirectional threaded rod 301 to rotate. This rotational motion then causes the threaded block 302, which is connected to the outer thread of the bidirectional threaded rod 301, to move accordingly. A horizontal plate 305 is fixed on the threaded block 302, and a clamping ring 303 is installed on the horizontal plate 305. The clamping ring 303 can move, thereby achieving effective clamping of wheel hub discs 2 of different specifications. A mechanical arm 11 is provided on the rear side of the frame 1. The outer side of the bidirectional threaded rod 301 is connected to the middle thread of the threaded block 302. A sliding limit rod 5 is provided on the outer side of the frame 1. The limit rod 5 is slidably connected to the bottom of the threaded block 302 to achieve the limiting function.

[0027] Reference Figure 2 , Figure 4 and Figure 5The cleaning mechanism 4 includes a placement block 401, which is located on the left side of the frame 1. A second motor 402 is located behind the placement block 401. A rotating rod 403 is located at the output end of the second motor 402. The kinetic energy of the second motor 402 drives the rotating rod 403 to rotate. A connecting rope 404 is located on the outer side of the rotating rod 403. A movable block 405 is located on the right side of the placement block 401. An elastic rope 406 is fixedly connected to the top of the movable block 405. A fan 407 is provided on the outside of the frame 5. The bottom of the moving block 405 is fixedly connected to the other end of the elastic rope 406. A sliding groove 7 is provided on the outside of the frame 1. The sliding groove 7 is opened in the middle of the placement block 401. The inner wall of the sliding groove 7 is slidably connected to the moving block 405. A vertical rod 8 is provided on the outside of the wheel hub 2. The outside of the vertical rod 8 is slidably connected to the wheel hub 2. The vertical rod 8 is used to stack the wheel hub 2. Multiple cleaning mechanisms can be provided, and the multiple cleaning mechanisms are respectively located in different positions.

[0028] Specifically, after starting motor 402, its output will drive the connected rotating rod 403 to rotate. During the rotation, the rotating rod 403 applies displacement to the moving block 405 through the connecting rope 404 wrapped around its outer side. The moving block 405 is equipped with an elastic rope 406. When the connecting rope 404 pulls the moving block 405 to move, the elastic rope 406 will elastically deform with the direction of movement, playing a role in resetting. When the tension of the connecting rope 404 weakens, the elastic rope 406 will drive the moving block 405 to return to its original position smoothly by its own elastic restoring force. The installed fan 407 moves accordingly to blow on the surface of the hub disc 2. The outer side of the frame 1 is provided with a sliding groove 7, which is opened in the middle area of ​​the mounting block 401. The inner wall of the sliding groove 7 is slidably connected to the moving block 405. The outer side of the hub disc 2 is provided with a vertical rod 8, which is slidably connected to the outer side of the hub disc 2 to support the hub disc 2.

[0029] Reference Figure 2 , Figure 3 and Figure 5 A support plate 6 is provided on the rear side of the frame 1. Sliding plates 9 are slidably connected to the top left and right sides of the support plate 6. The sliding plates 9 can move on the support plate 6, which will drive the motor 306 to move. The top of the sliding plate 9 is fixedly connected to the bottom of the motor 306. A robotic arm 10 is installed in the middle of the frame 1, which can pick up the wheel hub disc 2.

[0030] Specifically, a support plate 6 is provided on the rear side of the frame 1, and sliding plates 9 are provided on the top left and right sides of the support plate 6. The sliding plates 9 can slide and move on the support plate 6, thereby driving the motor 306 to move accordingly. The top of the sliding plate 9 is fixedly connected to the bottom of the motor 306. In addition, a robotic arm 10 is installed in the middle of the frame 1, which is used to pick up the wheel hub disc 2.

[0031] Working principle: During the processing of the wheel hub disc 2, the motor 306 is started. The kinetic energy of the motor 306 drives the bidirectional threaded rod 301 to rotate. The rotation of the bidirectional threaded rod 301 will drive the threaded block 302 connected to its outer thread to move. A horizontal plate 305 is installed on the threaded block 302, and a clamping ring 303 is installed on the horizontal plate 305. Finally, the clamping ring 303 can be moved to achieve clamping of wheel hub discs 2 of different specifications.

[0032] After the motor 402 is started, its output end drives the rotating rod 403 connected to it to rotate. During the rotation, the rotating rod 403 moves the moving block 405 by the connecting rope 404 wrapped around its outside. The moving block 405 is equipped with an elastic rope 406. When the connecting rope 404 pulls the moving block 405 to move, the elastic rope 406 will undergo elastic deformation with the direction of movement, which plays a role in resetting. When the tension of the connecting rope 404 weakens, the elastic rope 406 will drive the moving block 405 to return to its original position smoothly by its own elastic restoring force. The installed fan 407 moves to blow on the surface of the stacked wheel disc 2 located on the upright 8, cleaning the dust and debris attached to the surface.
