The front end of the connecting block is arc-shaped, and the two connecting blocks are symmetrical about the center of the circular seat. The connecting blocks are located on both sides of the second connecting groove and fixed with sliders. This application uses the action of the connecting rod to rotate, so that the two connecting blocks move simultaneously, and the distance between the two connecting blocks can be controlled and changed, so as to achieve the purpose of fixing most different specifications of elbows, reduce the frequency of replacing the fixing seat, and make the welding process more convenient.

[0004] In the process of welding elbows and pipe covers, the pre-process usually includes a pressing process, specifically, pressing the pipe cover and the elbow together through a pressing device, and then welding the joint of the elbow and the pipe cover through a welding device.

[0005] Regarding the above-mentioned related technologies, during the press-welding process of the elbow and the pipe cover, dust and impurities are adsorbed on the press-welding surface, thereby affecting the implementation of subsequent welding and the overall process. Therefore, there is an urgent need for an automotive elbow welding equipment to solve the above technical problems. Summary of the Invention

When not welded, the bottom end of the cleaning rod 3925 is higher than the top of the bend pipe 2 30, and the top of the cleaning rod 3925 is lower than the bottom end of the lifting block 381. Before welding, the staff first fixes the position of the second bend pipe 30. At this time, the fixing plate 352 moves toward the second bend pipe 30, driving the cleaning rod 3925 to move to the bottom of the lifting block 381, and then starting the welding cylinder 38. The lifting block 381 moves downward, driving the cleaning rod 3925 downward, so that the cleaning rod 3925 is located at the inner wall of the second bend pipe 30, and then the movable spring 3924 is used to make the cleaning rod 3925 closer to the inner wall of the second bend pipe 30. During welding, the driven wheel 392 rotates the gear Under the connection of strip 391, it rotates synchronously, and then drives the movable plate 3923 to rotate synchronously. Since the movable plate 3923 is rotatably connected with the movable rod 3922, the cleaning rod 3925 is located at the inner wall of the bend pipe 2 30. During the entire welding process, the movable plate 3923 is always facing the direction of the bend pipe 2 30, so that the cleaning rod 3925 is close to the inner wall of the bend pipe 2 30 during the welding process and rubs back and forth, avoiding the formation of welding slag condensation during the welding process, which is difficult to clean, and is beneficial to improving the welding efficiency of the equipment.

When the second elbow 30 needs to be fixed, the staff starts the clamping motor 325, which drives the clamping rod 326 to rotate, so that the clamping rod 326 abuts against the second elbow 30, thereby further improving the stability of the equipment.

[0046] The implementation principle of a welding device for automobile parts processing according to an embodiment of the present invention is as follows: when a bent pipe needs to be welded, the worker places the pipe cover 10 on the support plate 25, places the bent pipe 20 on the bent pipe groove 223 of the pressing plate 222, and starts the pressing cylinder 221. The pressing cylinder 221 drives the pressing plate 222 to move downward to achieve the pressing process of the bent pipe. During the downward movement, the lifting plate 261 is driven to move downward. Since the rotating plate 262 is threadedly connected to the support rod 24, the rotating plate 262 will rotate synchronously in the lifting plate 261. At the same time, since the bottom end of the inner cleaning rod 266 abuts against the bottom surface of the pressing groove 23, when the lifting plate 261 moves downward, the inner cleaning rod 266 moves upward, and is driven by the cleaning wheel 265 to synchronously move the outer cleaning rod 267 downward. During the pressing process, the outer cleaning rod 267 rotates downward to clean the outer wall of the tube cover 10 to ensure the smooth implementation of the pressing process, and the inner cleaning rod 266 rotates upward to clean the inner wall of the tube cover 10 to ensure the smooth implementation of the subsequent welding process; then the pressed bend pipe 2 30 is placed on the fixed seat 321 on the rotating disk 32 of the support seat 31, and the straight pipe part is placed in the positioning groove 342 of the positioning plate 341, and then the fixing cylinder 351 is started to move the fixing plate 352 toward the positioning plate 341, thereby fixing the position of the bend pipe 2 30, and the welding cylinder 38 is started to move the laser welding gun 382 downward to align with the position where the bend pipe 2 30 needs to be welded, and then the laser welding gun 382 and the rotating motor 33 are started to realize the process of rotating the welding bend pipe.

[0047] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
