[0002] A patent document with publication number CN119549960A discloses a positioning mechanism for welding in automotive parts processing, including a work platform and several adjustable limiting clamping mechanisms detachably connected to the work platform. The adjustable limiting clamping mechanism includes a lower support mechanism detachably connected to the work platform, two hinge point adjustment mechanisms symmetrically connected to the lower support mechanism, a torque adjustment mechanism fixedly connected to the hinge point adjustment mechanism, and an upper pressing mechanism located directly above the lower support mechanism. The lower support mechanism and the upper pressing mechanism are hinged through the hinge point adjustment mechanism. The hinge point of the clamp-type fixture in this invention can be automatically adjusted. While ensuring the clamp-type fixture can stably clamp the workpiece, the position and opening / closing state of the hinge area of ​​the clamp-type fixture can be adjusted, thereby adapting to the continuous welding process of a welding robot around the workpiece. This prevents the welding robot from being obstructed during continuous circling, resulting in low cost and high economic benefits.

[0003] The positioning components in the existing technology generally lack buffers. When positioning parts, rigid collisions are likely to occur between the positioning clamping components. This can not only cause scratches, dents and other damage to the surface of the parts, affecting their appearance quality and performance, but may also lead to positioning deviations and reduce welding accuracy.

[0004] Therefore, this utility model proposes a positioning device for automated welding of parts to solve the above problems. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of this utility model, not all embodiments, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0020] Example 1: Please refer to Figures 1 to 2 A positioning device for automated welding of parts includes a base 1, a support frame 2, and a welding head 3. The support frame 2 is fixedly arranged on both sides of the base 1, and the welding head 3 is arranged on the support frame 2. A sliding component 4, a positioning component 5, and a buffer component 6 are arranged on the base 1. The sliding component 4 is arranged on the base 1, the positioning component 5 is fixedly arranged on the sliding component 4, and the buffer component 6 is arranged on the positioning component 5.

[0021] The bidirectional lead screw 401 in the sliding assembly 4 is fixedly installed inside the base 1, and the bidirectional lead screw 401 is driven by the motor 402.

[0022] The sliding groove 403 in the sliding assembly 4 is set on the base 1. The sliding block 404 is slidably embedded in the sliding groove 403. The sliding block 404 is fixedly set on the interlocking ring 405. The interlocking ring 405 is slidably embedded on both sides of the bidirectional lead screw 401.

[0023] In use, place the parts to be welded in a suitable position on the base 1, start the motor 402, the motor 402 drives the bidirectional lead screw 401 to rotate, and drive the interlocking ring 405 to move on the lead screw. The positioning component 5 slides smoothly along the sliding groove 403 through the sliding block 404. According to the size of the parts and the positioning requirements, the speed and direction of the motor 402 are precisely controlled, the position of the positioning component 5 is flexibly adjusted, and it is quickly moved to a position close to the parts to prepare for precise positioning.

[0024] Example 2: Based on Example 1, please refer to... Figures 2 to 3 The positioning block 501 in the positioning component 5 is fixedly mounted on the sliding block 404, and the end of the positioning block 501 is provided with a snap-fit ​​groove 502.

[0025] The positioning component 5 has a snap-fit ​​protrusion 503 that is adapted to slide and engage in the snap-fit ​​groove 502, and a positioning ring 504 is provided on the snap-fit ​​protrusion 503.

[0026] When in use, after the positioning component 5 approaches the part, the snap-fit ​​groove 502 at the end of the positioning block 501 is aligned with the edge or specific part of the part, and the snap-fit ​​protrusion 503 slides and adjusts in the snap-fit ​​groove 502, causing the positioning ring 504 to fit against the surface of the part. By finely adjusting the bidirectional lead screw 401, the positioning ring 504 tightly surrounds the part, clamping it firmly from multiple angles, achieving precise positioning of the part, and ensuring stable position during welding.

[0027] Example 3: Based on Example 2, please refer to... Figures 3 to 4 The telescopic heads 601 in the buffer assembly 6 are evenly arranged in the buffer pads 602 at the bottom end of the positioning ring 504, and springs 603 are fixedly sleeved on the outside of the telescopic heads 601.

[0028] During use, the buffer assembly 6 starts working the instant the positioning ring 504 contacts the component. The telescopic head 601 is compressed and retracts within the buffer pad 602, and the spring 603 is compressed accordingly, effectively absorbing the impact force during the positioning process. Even in the case of automated rapid positioning, the impact force can be dissipated, avoiding damage such as scratches and dents on the surface of the components. At the same time, the stable buffering effect prevents positioning deviation caused by collisions, ensuring welding accuracy. In addition, this buffering mechanism can also reduce hard friction between various components inside the positioning device, improve the stability of equipment use, extend the overall service life of the equipment, and reduce maintenance costs.

[0029] 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.
