[0002] With the rapid development of the bicycle manufacturing industry, the frame, as a core component, directly affects the overall performance and production efficiency of the bicycle due to its processing precision and efficiency. In traditional processing, the frame is prone to deviations due to its complex structure (multi-tube welding, various angles) and the difficulty of manual positioning, resulting in unstable welding quality and high rework rate. In addition, the market demand is developing towards lightweight and personalized products, which puts forward higher requirements for frame processing. To meet these challenges, auxiliary positioning devices have emerged. Through mechanized and standardized positioning, processing precision is improved, reliance on manual labor is reduced, and diversified production needs are met.

[0003] However, existing auxiliary positioning devices are usually custom-made for a specific model of frame and can only perform auxiliary positioning operations on the specified frame. However, due to different customer needs, frame sizes and rear forks vary, and specific auxiliary positioning brackets cannot meet the positioning needs of various frames. Special customization is required for various frames, which affects production efficiency.

[0004] Therefore, we provide an auxiliary positioning device to solve the above problems. Utility Model Content

[0020] 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.

[0021] Please see Figure 1-4 As shown, this utility model provides a technical solution: an auxiliary positioning device, including a fixed bracket 1 and an auxiliary positioning and rotation height adjustment frame clamping mechanism 2, wherein the auxiliary positioning and rotation height adjustment frame clamping mechanism 2 is provided on the inner side of the fixed bracket 1;

[0022] The auxiliary positioning and rotation height adjustment frame clamping mechanism 2 includes a frame bottom sleeve fixing component 21, a double-end engagement type rotation angle adjustment component 22, an auxiliary fixing component 23, a height adjustment component 24, and a frame fork positioning clamping component 25. The frame bottom sleeve fixing component 21 is provided on the inner side of the fixing bracket 1. The double-end engagement type rotation angle adjustment component 22 is provided at the rear end of the frame bottom sleeve fixing component 21. The auxiliary fixing component 23 is provided on the upper side of the double-end engagement type rotation angle adjustment component 22. The height adjustment component 24 is provided on one side of the auxiliary fixing component 23. The frame fork positioning clamping component 25 is provided on one side of the height adjustment component 24.

[0023] Furthermore, the frame bottom mounting assembly 21 includes a clamping platform 211, a frame bottom positioning sleeve 212, and fixing rods 213. The clamping platform 211 is welded and fixed to the inner side of the fixing bracket 1, and the frame bottom positioning sleeve 212 is fixedly connected to the inner side of the clamping platform 211. Fixing rods 213 are fixedly connected to both sides of the rear end of the clamping platform 211. Figure 1 It can be seen that the bottom positioning sleeve 212 of the frame is located in the arc-shaped groove in the middle of the clamping platform 211. During the process of fitting the bottom support of the frame, the groove can limit the two ends of the support sleeve to prevent it from shifting during the fixed positioning process.

[0024] Furthermore, the double-end meshing rotation angle adjustment assembly 22 includes an adjusting rotation gear 221, a fixed arc rod 222, a fixed sleeve 223, and bearing balls 224. The adjusting rotation gear 221 is movably sleeved on the side of the fixed support rod 213 closest to the clamping platform 211. The fixed arc rod 222 is fixedly connected to one side of the adjusting rotation gear 221. The fixed sleeve 223 is clamped and fixed inside the fixed arc rod 222. Bearing balls 224 are installed at the connection between the inner side of the fixed sleeve 223 and the fixed support rod 213. Figure 2It can be seen that an adjusting rotating gear 221 is movably sleeved on the surface of the fixed support rod 213 at both ends, and the gears at both ends are meshed. During the adjustment process, by rotating the adjusting rotating gear 221 at one end, the other end will rotate in the opposite direction as one side rotates, thereby performing angle opening and closing operations on the upper auxiliary fixing component 23, so that the auxiliary fixing component 23 can adapt to the frame clamping and positioning operations of different opening and closing scales.

[0025] Furthermore, the auxiliary fixing component 23 includes a support platform 231, fastening bolts 232 and a frame top positioning support rod 233. The support platform 231 is fixedly connected to the top thread of the fixing sleeve 223 by the fastening bolts 232, and the frame top positioning support rod 233 is welded and fixed to the upper side of the support platform 231.

[0026] Furthermore, the height adjustment assembly 24 includes a fixed support rod 241, a sliding rubber sleeve 242, a fixed clamp 243, and a fixed rod 244. The fixed support rod 241 is fixedly connected to the inner side of the top positioning support rod 233 of the frame. The sliding rubber sleeve 242 is slidably sleeved on the surface of the fixed support rod 241. The fixed clamp 243 is fixedly connected to the outer end of the sliding rubber sleeve 242. The fixed rod 244 is fixedly connected to the front end of the fixed clamp 243. During the adjustment process, the sliding rubber sleeve 242 is manually assisted to slide on the surface of the fixed support rod 241, so that the fixed rod 244 at the front end drives the entire frame fork positioning clamping assembly 25 to perform height adjustment operations, thereby coping with frame positioning clamping operations of different sizes and heights.

[0027] Furthermore, the frame fork positioning and clamping assembly 25 includes a rotary pin 251, a semi-circular clamping sleeve 252, an anti-slip rubber sheet 253, and a plug-in fastening screw 254. The semi-circular clamping sleeve 252 is movably inserted into the front end of the fixed rod 244 via the rotary pin 251. The anti-slip rubber sheet 253 is fixedly adhered to the arc-shaped inner wall of the semi-circular clamping sleeve 252, and the plug-in fastening screw 254 is threadedly connected to the outer end of the semi-circular clamping sleeve 252. Figure 3 It can be seen that the entire frame fork positioning and clamping assembly 25 is installed on the surface of two adjacent fixed support rods 241 at both ends, and the semi-circular clamping sleeve 252 at its front end can be opened and closed when not clamping. During clamping, it is fixed by threaded connection through the plug-in fastening screw 254 at the outer end.
