The stabilizing member 22 is arranged in a circumferential shape on the supporting substrate 1 for clamping the automobile parts at multiple points. A pressing member 23 for assisting the top surface of the automobile parts to stabilize and avoid shaking is arranged opposite to the action surface of the positioning device 21. The stabilizing member 22 pushes the automobile parts from bottom to top and clamps the edge of the automobile parts, thereby establishing a support surface formed along the shape of the automobile parts. The automobile parts are supported in different directions to enhance the stability of the automobile parts during welding. In this embodiment, the maximum clamping height of the clamping end 221 for the automobile parts is not less than the maximum supporting height of the push rod 211 for the automobile parts, that is, when there is no hole on the surface of the automobile parts that can be matched with the positioning device 21, the clamping end 221 can be used alone to clamp the automobile parts to prevent them from contacting with the positioning device 21, thereby preventing the positioning device 21 from scratching the surface of the automobile parts.

The driving source of the telescopic arm 222 in this specific embodiment is a cylinder. The cylinder is installed in the telescopic arm 222. The telescopic arm 222 specifically includes an outer arm that wraps the cylinder and an inner arm that is connected to the free end of the cylinder. Under the action of the controller, the inner arm is ejected or retracted, thereby forming a height control of the clamping end 221, and the clamping end 221 is rotatably installed on the inner wall. The rotation of the clamping end 221 is driven by a driving motor installed on the inner shaft to drive the rotation angle.

The connecting arm 232 is vertically connected to the support frame 231, and a through groove for installing the pressure stabilizing plate 233 is opened on its structure; the pressure stabilizing plate 233 includes a hydraulic cylinder arranged in the through groove and a top plate connected to the hydraulic cylinder, and the hydraulic cylinder pushes the top plate to move from top to bottom and contact the top surface of the automobile parts.

[0030] In this specific embodiment, the support substrate 1 is provided with inner grooves 4 arranged in a crisscross pattern, and the opening positions of the inner grooves 4 are adapted to the installation positions of the stabilizing member 22 and the positioning device 21. Each inner groove 4 is provided with a pushing member 5 for pushing the structure placed in the inner groove 4. The pushing member 5 is specifically a cylinder in this embodiment, which is installed in the inner groove 4 and its installation position is located at the end of the inner groove 4, such as Figure 2 As shown in the figure, the free end of the cylinder is connected to the base 223 or the telescopic rod 212, thereby driving the base 223 and the telescopic rod 212 to move synchronously with the free end, so that it moves in the inner groove 4, thereby adapting to the different shapes and sizes of the vehicle body frame and flexibly adjusting its support or clamping of the vehicle body frame or the vehicle panel.
