[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0020] Please see Figures 1-4 As shown, a needle feeding and straightening wire cutting mechanism for a welding assembly machine includes a fixed mounting frame 1, which is the foundation of the entire mechanism and is used to stably fix all other components. Adjustment structures 2 are provided on both sides of the fixed mounting frame 1, which are used to adjust the distance between guide mounting rails 3. The guide mounting rails 3 are slidably engaged inside the fixed mounting frame 1 to support and guide the adjustment structure 4 and its upper components. The adjustment structure 4 is installed inside the guide mounting rails 3, and its main function is to fine-tune the position of the support positioning frame 5 to ensure that the connecting wire wheel 6 can be accurately positioned as required, which is crucial for achieving accurate wire cutting. The upper end of the adjustment structure 4 is engaged with the support positioning frame 5 to support and fix the frame of the connecting wire wheel 6. The connecting wire wheel 6 is transferred inside the support positioning frame 5 to guide and cut the connecting wire.

[0021] The adjusting structure 2 includes an adjusting threaded rod 201, which engages with the internal threads of other sliding parts to achieve precise distance adjustment. The fixed mounting bracket 1 has rotating mounting holes on both sides. The adjusting threaded rod 201 is rotatably engaged within these rotating mounting holes. An adjusting motor 202 is fixedly mounted at one end of the adjusting threaded rod 201. The output end of the adjusting motor 202 is fixedly connected to the adjusting threaded rod 201. The main body of the adjusting motor 202 is fixedly connected to the fixed mounting bracket 1. When the distance between the guide mounting rails 3 needs to be adjusted, the adjusting motor 202 starts and drives the adjusting threaded rod 201 to rotate. Due to the engagement of the threads, the guide mounting rails 3 move along the direction of the threaded rod, thus achieving precise distance adjustment. This design not only improves the versatility and flexibility of the cutting mechanism but also ensures the accuracy and stability of the cutting process.

[0022] The guide mounting rail 3 is designed with adjustable sliders at both ends. The adjustable sliders are slidably engaged inside the fixed mounting bracket 1. One end of the adjustable slider has an adjustable threaded hole inside, which is threadedly connected to the adjustable threaded rod 201. The other end of the adjustable slider has a connecting sliding hole inside, which is slidably engaged with the adjustable threaded rod 201. When the adjustable motor 202 starts and drives the adjustable threaded rod 201 to rotate, the adjustable slider at one end will move along the direction of the threaded rod, while the adjustable slider at the other end will remain in the same position. Since the guide mounting rail 3 is supported and guided by these two sliders, it will slide smoothly to the required position, thereby achieving precise adjustment of the distance between the guide mounting rails 3.

[0023] The adjustment structure 4 includes an adjustment threaded rod 401. A positioning adapter hole is provided inside the guide mounting rail 3. The adjustment threaded rod 401 is rotatably engaged inside the positioning adapter hole. An adjustment bevel ring 402 is fixedly fitted at one end of the adjustment threaded rod 401. An adjustment power hole is provided on one side of the guide mounting rail 3. An adjustment motor 403 is embedded inside the adjustment power hole. A drive bevel gear 404 is fixedly installed at the output end of the adjustment motor 403. The drive bevel gear 404 and the adjustment bevel ring 402 mesh with each other. When it is necessary to adjust the position of the support positioning frame 5, the adjustment motor 403 starts and drives the drive bevel gear 404 at its output end to rotate. Since the drive bevel gear 404 and the adjustment bevel ring 402 mesh with each other, the adjustment threaded rod 401 will rotate accordingly. Due to the engagement of the threads, the support positioning frame 5 will move along the direction of the adjustment threaded rod 401, thereby achieving precise position adjustment.

[0024] The guide mounting rail 3 has a sliding block 405 inside, which is slidably engaged with the guide mounting rail 3. The guide mounting rail 405 has a guide threaded hole inside, which is threadedly connected to the adjusting threaded rod 401. The guide mounting rail 405 has combination connection holes on both sides. The lower end of the support positioning frame 5 has an assembly plate 501 on both sides, which has a connection threaded hole on both sides. The connection threaded hole is threadedly connected to the combination bolt 502. The support positioning frame 5 has a rotating connecting shaft 503 fixedly installed inside, and the connecting thread wheel 6 is mounted on the rotating connecting shaft 503. When the adjusting motor 403 starts and drives the adjusting threaded rod 401 to rotate, the guide mounting rail 405 will move along the direction of the threaded rod. Since the support positioning frame 5 is fixedly connected to the guide mounting rail 405 through the assembly plate 501 and the combination bolt 502, the support positioning frame 5 and the connecting thread wheel 6 on it will also move to the required position. This design not only improves the versatility and flexibility of the cutting mechanism, but also ensures the accuracy and stability of the cutting.
