[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a welding fixture for automotive door panels, including a mounting base 1, a positioning groove 2 on the surface of the mounting base 1, a telescopic cylinder 5 fixedly mounted on the side wall of the mounting base 1, a fixing plate 6 fixedly mounted on the movable end of the telescopic cylinder 5, a stabilizing mechanism 3 and a promoting mechanism 4 on the outer side of the fixing plate 6, the stabilizing mechanism 3 including a threaded hole 301, a clamping block 302, a threaded rod 303, a moving block 304, a straight rod 305, a torsion spring 306, a gripper 307, and a rubber pad 308.

[0025] In one embodiment of this utility model, a threaded hole 301 is formed on the surface of a fixing plate 6. A clamping block 302 is detachably bolted to the surface of the fixing plate 6. A threaded rod 303 is movably connected to the side wall of the clamping block 302. A movable block 304 is threadedly connected to the surface of the threaded rod 303. A straight rod 305 is fixedly connected to the surface of the movable block 304. One end of a torsion spring 306 is fixedly connected to the surface of the straight rod 305. The other end of the torsion spring 306 is fixedly connected to the inner wall of a gripper 307. A rubber pad 308 is fixedly installed on the surface of the gripper 307.

[0026] In addition, the promoting mechanism 4 includes a moving groove 401, which is formed on the surface of the clamping block 302. A return spring 402 is fixedly connected to the inner wall of the moving groove 401. A positioning block 403 is fixedly connected to one end of the return spring 402 away from the inner wall of the moving groove 401. An arc-shaped pad 404 is fixedly installed on the surface of the positioning block 403. A guide ball 405 is fixedly installed on the arc surface of the positioning block 403. A guide groove is formed on the inner wall of the moving groove 401. The shape of the guide groove matches the shape of the guide ball 405. Two sets of guide balls 405 are arranged in a circumferential array and fixedly installed on the arc surface of the positioning block 403.

[0027] In this embodiment of the utility model, the positioning block 403 is T-shaped, the arc surface of the arc pad 404 is away from the surface of the positioning block 403, and the arc surface of the arc pad 404 can fit the irregular surface of the door panel. The surface of the gripper 307 is provided with a rotating hole, the diameter of which is adapted to the diameter of the straight rod 305. The gripper 307 is sleeved on the outside of the straight rod 305, and the gripper 307 can rotate outside the straight rod 305. The gripper 307 is initially set accordingly so that the gripper 307 cooperates with the torsion spring 306. The surface of the door panel is clamped. The surface of the clamping block 302 is provided with an adjustment groove. The shape of the adjustment groove is adapted to the shape of the moving block 304. The moving block 304 can move inside the adjustment groove. The surface of the moving block 304 is provided with a groove. The shape of the groove is adapted to the shape of the straight rod 305, so that the straight rod 305 can be fixedly installed on the surface of the moving block 304. The clamping block 302 is fixed to the surface of the fixing plate 6 by bolts, which is convenient for adapting to different heights of the door panel, thereby fixing the door panel.

[0028] In this utility model, when in use, the door panel is placed inside the positioning groove 2, the telescopic cylinder 5 is activated to clamp the edge of the door panel with the fixing plate 6, the claws 307 on the moving block 304 clamp the irregular surface of the door panel under the action of the torsion spring 306, the rubber pad 308 makes the claws 307 stably fixed to the surface of the door panel, and then the threaded rod 303 is adjusted to move the moving block 304 to a suitable position to stably clamp the surface of the door panel.

[0029] Furthermore, as the fixed plate 6 moves, the positioning block 403 enters the surface of the door panel and presses against the return spring 402, causing the return spring 402 to deform. This provides a certain buffer protection for the fixed plate 6 clamping the surface of the door panel. Simultaneously, as the positioning block 403 moves, the guide ball 405 moves inside the guide groove, causing the arc-shaped pad 404 to twist upon contact with the arc surface of the door panel. This allows the arc-shaped pad 404 to better conform to the irregular surface of the door panel, ensuring stable clamping of the door panel.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
