[0002] At present, welding technology is usually involved in the processing of metal instruments or welded parts. Electric welding is a welding operation that melts the metal parts to be connected by using the high-temperature arc generated by the welding gun. During the processing and production of automobile parts, welding work is needed. During the welding of automobile parts, positioning is used to fix and position the automobile parts, so that the fusion between the welded parts is better.

[0003] According to the automobile welding part welding positioning mechanism (announcement number: CN221676236U) disclosed, the above-mentioned application is set up by the cooperation of the welding table, the positioning strip, the hydraulic cylinder, the supporting rod and the flue gas cleaning box, which is beneficial to moving the positioning strip downward by the hydraulic cylinder during welding, and the positioning strip is fixed and positioned by pressing the welding part, preventing the welding part from shaking during welding and affecting the welding quality.

[0004] However, the above-mentioned device can press and fix the different welding parts by adjusting the height during actual use, but the vibration generated during welding can easily cause small displacement and sliding of the rigidly pressed parts, and thus the final welding effect is flawed.

[0009] Preferably, the number of friction strips is several, and the several friction strips are arranged in a linear array on the outer wall of the L-shaped rubber plate.

[0010] Preferably, the outer wall of the extrusion inclined plate is matched with the outer wall of the pressure receiving inclined plate, so that the extrusion inclined plate can smoothly extrude the pressure receiving inclined plate.
