[0041] The automobile sheet metal welding fixture can adapt to the automobile sheet metal after slight adjustment without the need of resetting the welding program or changing the fixture to adapt to the slight adjustment of the automobile sheet metal.

[0042] As shown in Figure 2 and Figure 3 In one embodiment, the clamping assembly 12 comprises a first clamping unit 13; the first clamping unit 13 comprises a clamping support 14, a positioning group 15 arranged on the clamping support 14, and a clamping group 16; the positioning group 15 comprises a positioning cylinder 151 arranged on the clamping support 14, and a positioning pin 152 arranged on the output end of the positioning cylinder 151; the clamping group 16 comprises a clamping fixed block 161 arranged on the clamping support 14, a clamping cylinder 162 arranged on the clamping support 14, and a clamping arm 163 hinged on the clamping support 14; the clamping arm 163 is provided with a hinge part hinged with the clamping support 14, a first arm end connected with the driving end of the clamping cylinder 162, and a second arm end matched with the clamping fixed block 161. In this way, the clamping cylinder 162 drives the first arm end of the clamping arm 163 to swing, and the second arm end forms a clamping position with the clamping fixed block 161 for clamping the automobile sheet metal.

[0043] In one embodiment, the second arm end is provided with a clamping block 164, and the clamping block 164 is a rubber block. In this way, the clamping block 164 and the clamping fixed block 161 form a clamping position for clamping the automobile sheet metal, and the elastic deformation of the rubber block can avoid the deformation of the automobile sheet metal caused by excessive clamping force.

[0044] In one embodiment, the clamping fixed block 161 is a plastic block detachably connected to the clamping support 14, and the hardness of the plastic block is greater than that of the rubber block.

[0045] In one embodiment, the mounting base 11 is provided with a plurality of uniform mounting holes, and the first clamping unit 13 is detachably mounted on the mounting holes through a connecting structure. Specifically, the connecting structure is a threaded connection structure or a bolt and nut connection structure. In this way, according to the actual structure of the automobile sheet metal, the connecting position of the first clamping unit 13 on the mounting base 11 is adjusted, so as to realize the clamping and fixing position of different automobile sheet metals on the fixture main body 1.

[0046] In one of the embodiments, the positioning group 15 further comprises a positioning guide seat 153 arranged on the clamping support 14, and the positioning pin 152 is provided with a guide round rod part matched with the positioning guide seat 153.

[0047] In one of the embodiments, the top end of the positioning pin 152 is provided with a tapered part.

[0048] As shown in Figure 1 and Figure 4 In one of the embodiments, the first rotating assembly 21 comprises a first rotating plate 211 and a first driving unit 212 for driving the first rotating plate 211 to rotate, and the mounting bottom plate 11 is connected to the first rotating plate 211. In this way, the horizontal rotating action of the mounting bottom plate 11 is realized by driving the first rotating plate 211 to rotate through the first driving unit 212.

[0049] In one of the embodiments, the second rotating assembly 22 comprises a rotating arm 221 and a second driving unit 222 arranged at both ends of the rotating arm 221, and the first driving unit 212 is arranged on the rotating arm 221.
