The suction assembly 24 is used to suck and hold the door panel on the profiled carrier assembly 22.

[0024] Specifically, two fixtures 2 are arranged on the workbench 1. The door panel is placed on the profiled carrier assembly 22. The suction assembly 24 on the profiled carrier assembly 22 sucks and holds the side end and the bottom of the door panel. The positioning assembly 23 positions the part of the door panel located on the profiled carrier assembly 22. When welding the door panel is required, the clamping assembly 25 clamps each part of the door panel, so that the door panel is firmly fixed on the profiled carrier assembly 22.

[0025] In the above structure, through the mutual cooperation of the profiling carrier assembly 22, the positioning assembly 23, the suction assembly 24, and the clamping assembly 25, the precise positioning, strong suction, and accurate clamping operations of the car door panel are realized. This car door panel clamping fixture is not only convenient and simple to operate, but also improves the positioning accuracy and the firmness of fixation, thereby improving the welding accuracy and ensuring the qualified rate after welding.

[0026] As Figure 1 shown, in one embodiment, the profiling carrier assembly 22 of the car door panel clamping fixture includes a plurality of profiling carrier platforms 221, and the plurality of profiling carrier platforms 221 are respectively adapted to various parts of the door panel.

[0027] Specifically, the profiling carrier assembly 22 includes 5 profiling carrier platforms 221, and the profiling carrier platforms 221 respectively correspond to various parts of the door panel. This setting facilitates the positioning of the door panel.

[0028] As Figure 1 shown, in one embodiment, the positioning assembly 23 of the car door panel clamping fixture includes a plurality of positioning plates 231, the plurality of positioning plates 231 are respectively wound around one side of the profiling carrier assembly 22, and the plurality of positioning plates 231 are respectively used to position the two ends and the side ends of the door panel on the profiling carrier assembly 22.

[0029] Specifically, the positioning assembly 23 includes 7 positioning plates 231, and the positioning plates 231 are respectively installed at the side ends of the 5 profiling carrier platforms 221.

The first cylinder 251 is inclined and installed on the workbench 1. The driving end of the first cylinder 251 is hinged to the turning plate 254. The middle part of the turning plate 254 is fixedly connected to the rotating shaft 253. The two fixed seats 252 are respectively installed at both ends of the side of the workbench 1. Both ends of the rotating shaft 253 are rotatably connected to the two fixed seats 252. A plurality of pressing parts are arranged on the rotating shaft 253. The pressing part includes a connecting plate 255 and a first pressing head 256. One end of the connecting plate 255 is fixedly connected to the rotating shaft 253, and the other end of the connecting plate 255 is connected to the first pressing head 256. The first cylinder 251 is used to drive the rotating shaft 253 to drive a plurality of first pressing heads 256 to rotate to press the door panel on the profiling carrier assembly 22.

[0033] Specifically, 8 pressing parts are arranged on the rotating shaft 253.
