For automobile parts of different sizes, the two sliders can be pulled to move along the slide rails, thereby changing the distance between the two pressure plates to adjust the fixing range of the fixture, so that the fixture can clamp automobile parts of different sizes.

[0009] In a preferred embodiment, the upper surface of the fixing groove is slidably connected to a limiting plate.

[0010] Through the above technical solution, after the automobile component is placed in the fixing groove, the automobile component is fixed between the limiting plate and the inner wall of one side of the fixing groove by pulling the limiting plate, thereby preventing the automobile component from moving during the spot welding process.

[0011] In a preferred embodiment, a plurality of threaded holes are provided on the upper surface of the right side of the fixing groove, and a plurality of locking grooves are provided on the upper surface of the limiting plate.

[0012] Through the above technical solution, after the limit plate is moved, the position of the limit plate is fixed by passing the bolts through the locking groove and the threaded hole in sequence.

[0013] In a preferred embodiment, a pressing sheet is inserted into the end of the pressing rod.

[0014] Through the above technical solution, relatively small automobile parts can be pressed and fixed by the pressing sheet.

[0015] In a preferred embodiment, a positioning hole is provided on one side of the pressing sheet.

[0016] Through the above technical solution, during the spot welding process, the welding points can be determined through the positioning holes.

[0017] In a preferred embodiment, anti-slip pads are fixedly installed at the four corners of the bottom of the fixing plate.

[0019] Place the auto parts to be spot welded into the fixing groove, and the connecting plate is driven downward by the cylinder. At this time, the pressure plate moves downward to press the upper surface of the auto parts, thereby clamping and fixing the auto parts. For auto parts of different sizes, the two sliders can be pulled to move along the slide rails, thereby changing the distance between the two pressure plates to adjust the fixing range of the fixture, so that the fixture can clamp auto parts of different sizes.
