[0002] In the field of bicycle manufacturing, the paint spraying of a bicycle frame is an important production link. In order to ensure the quality of paint spraying, the bicycle frame needs to be stably and accurately clamped during the paint spraying process.
[0003] Traditional bicycle frame paint spraying clamping devices often have many limitations. On the one hand, most existing devices can only adapt to bicycle frames of specific sizes and shapes. When the specifications of the bicycle frame change, for example, the pipe diameter, length or shape of the bicycle frame are different, the existing clamping device cannot be flexibly adjusted to adapt to the new bicycle frame, which results in the need to frequently replace or adjust the clamping tooling when producing different models of bicycles, greatly reducing the production efficiency and increasing the production cost. Therefore, a paint spraying tooling for bicycle frame machining is needed to solve the above problems. SUMMARY

[0023] The present invention will be further described below with reference to the embodiments.
[0024] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.
[0025] Please see Figures 1-6 This utility model provides a painting fixture for bicycle frame processing, including a machine block 1. A first electric push rod 2 is fixedly mounted on the machine block 1. A threaded positioning rod 4 is fixedly mounted on the top of the first electric push rod 2 via a connecting block 3. A bicycle frame 5 is positioned and sleeved on the threaded positioning rod 4. Movable grooves 6 are provided on both sides of the machine block 1. A threaded rod 7 is rotatably mounted inside each movable groove 6. A displacement block 8 is threadedly connected to the outside of each threaded rod 7. A second electric push rod 9 is fixedly mounted on one side of each displacement block 8. A connecting arm 10 is fixedly mounted on one end of each second electric push rod 9. A clamping block 11 is fixedly mounted on the near ends of the two connecting arms 10. An insert block 12 is fixedly mounted on the near side of each clamping block 11. The lower sides of the bicycle frame 5 are clamped by two clamping blocks 11. Two insert blocks 12 are inserted into the through holes on both sides of the bicycle frame 5. By setting the threaded positioning rod 4, the first electric push rod 2 drives the threaded positioning rod 4. The lifting and lowering of the positioning rod 4 allows for convenient adjustment of the height of the frame 5, meeting the vertical positioning requirements of different frames. The rotation of the threaded rod 7 in the moving groove 6 causes the displacement block 8 to move. Combined with the extension and retraction of the second electric push rod 9, which drives the connecting arm 10 and the clamping block 11, the distance between the two clamping blocks 11 can be precisely adjusted to adapt to the clamping requirements of frames 5 of different widths and lengths. The design of the insert block 12 on the clamping block 11 inserting into the through holes on both sides of the frame 5 further enhances the positioning stability of the frame 5, effectively preventing the frame from shaking or shifting during the painting process. This structural design greatly improves the adaptability of the tooling to bicycle frames of different sizes and shapes, reduces the time cost of frequently changing tooling due to frame differences, significantly improves the overall efficiency and quality of bicycle frame painting, ensures that the painting operation can evenly and accurately cover the frame surface, and improves the appearance quality and production efficiency of the product.
[0026] Each displacement block 8 is slidably positioned within its corresponding moving slot 6.
[0027] A threaded sleeve rod 13 is threadedly connected to the threaded positioning rod 4. A retaining block 14 is fixedly installed on the outside of the threaded sleeve rod 13, and a throttle rod 15 is fixedly installed at the top of the threaded sleeve rod 13.
[0028] Each threaded rod 7 has a worm gear 16 at one end of its rotating part, and connecting blocks 17 are fixedly installed on both sides of the machine block 1.
[0029] Two connecting blocks 17 are rotatably mounted on adjacent sides with worm gears 18, and two worm wheels 16 mesh with the worm gears 18.
[0030] A drive motor 19 is installed at one end of the worm gear 18. The drive motor 19 is fixedly mounted on a connecting block 17 on one side via a fixing block 20. By setting a threaded positioning rod 4, the threaded connection between the threaded sleeve rod 13 and the threaded positioning rod 4, and the setting of the abutment block 14, the position of the frame 5 on the threaded positioning rod 4 can be finely adjusted and tightened by rotating the throttle lever 15, which enhances the flexibility and stability of the frame positioning. The combination of the worm wheel 16, the worm gear 18, and the drive motor 19 makes the rotation control of the threaded rod 7 more convenient and efficient. The drive motor 19 can precisely drive the worm gear 18 to rotate, thereby driving the worm wheel 16 and the threaded rod 7 to rotate synchronously, accurately adjusting the spacing of the clamping block 11. The high degree of automation and high adjustment accuracy reduce the complexity and error of manual operation, greatly improving the overall working efficiency and reliability of the tooling. This makes the entire painting tooling perform better in dealing with the processing needs of different frames, and helps to improve the consistency and quality rate of bicycle frame painting production.
[0031] The working principle and usage process of this utility model are as follows: First, the frame 5 is placed on the threaded positioning rod 4 for initial positioning. The first electric push rod 2 is activated, which drives the threaded positioning rod 4 to rise or fall through the connecting block 3, so that the frame 5 reaches a suitable height position. Then, the drive motor 19 runs, driving the worm gear 18 to rotate. Since the worm wheel 16 and the worm gear 18 mesh with each other, the threaded rod 7, which is coaxial with the worm wheel 16, rotates in the moving groove 6, thereby causing the displacement block 8 to slide in the moving groove 6, realizing the horizontal spacing adjustment of the two clamping blocks 11 to adapt to the frame 5. Width: When the clamping block 11 approaches the sides of the frame 5, the second electric push rod 9 extends or retracts, driving the clamping block 11 to precisely fit the frame 5 through the connecting arm 10, and causing the insert block 12 to be inserted into the through holes on both sides of the frame 5, thus completing the stable clamping of the frame 5. If it is necessary to fine-tune and tighten the position of the frame 5 on the threaded positioning rod 4, the throttle lever 15 can be rotated to drive the threaded sleeve rod 13 to rotate, and the retaining block 14 is used to further position and reinforce the frame 5, thereby ensuring that the frame 5 can always maintain a stable posture during the painting process, so as to obtain a high-quality and uniform painting effect.
