[0030] The welding machine auxiliary tool clamp is provided with at least three positioning assemblies 200, the positioning assemblies 200 are detachably installed on the platform 100, the positioning assembly 200 comprises an insertion block 210 provided with a sliding groove 2111, in use, the position of the positioning assembly 200 on the platform 100 can be adjusted according to the size of the gasket to be clamped, that is, the position of the insertion block 210 is moved and then the connecting bolt 230 is locked, in this way, gaskets of different diameters can be matched, and when the gasket does not need to be placed for machining, the positioning assembly 200 can be detached from the platform as required to prevent unnecessary interference during machining. It should be noted that the number of connecting screw holes 110 provided on the platform 100 can be greater than or equal to the number of positioning assemblies 200, at least three connecting screw holes 110 and three positioning assemblies 200 are provided, and the adjacent positioning assemblies 200 are at an angle of 120 degrees to ensure the stability of the gasket 10. In order to further improve the stability, the number of positioning assemblies 200 can be appropriately increased, and the angle between adjacent positioning assemblies 200 can be reduced. It should be noted that in some embodiments, the guide 220 is a nut, and in this embodiment, the guide 220 is a guide block matched with the sliding groove 2111.

[0031] Referring to Figures 1-6 In an embodiment, the insertion block 210 has a first end 211 and a second end 212 away from each other, the first end 211 is provided with a sliding groove 2111, and the sliding groove 2111 is provided with a slope portion 2112 on both sides of the opening, and the thickness of the slope portion 2112 gradually decreases from the side close to the second end 212 to the side away from the second end 212.

[0032] In an embodiment, the thickness of the second end 212 is greater than or equal to the maximum thickness of the slope portion 2112.

[0033] For comparison, see Figure 3 and Figure 6 As shown in Figure 3 , when a thicker gasket is used during machining, the first end 211 is adjusted to the outer side, so that the second end 212 abuts against the outer diameter of the gasket, and the thickness of the second end 212 is larger, which is more suitable for the thicker gasket 10 and the positioning is more stable. As shown in Figure 6 , when a thinner gasket 10 is used during machining, the second end 212 is adjusted to the outer side, so that the first end 211 abuts against the outer diameter of the gasket 10, and the thickness of the first end 211 is smaller, so that the end of the insertion block 210 does not interfere with the holder 20 placed on the upper part of the gasket 10, which is more suitable for the thinner gasket 10 and the positioning is more stable.

[0034] Referring to Figure 7 In an embodiment, an end threaded hole 2121 is arranged close to the second end 212, and a heightening column 2122 is connected to the end threaded hole 2121.

The connecting screw holes 110 in the same set are located on the same radius circle, and the connecting screw holes 110 in different sets are located on different radius circles. In this way, according to the size of the gasket 10 used, the appropriate connecting screw hole 110 can be selected to fix the positioning assembly 200. The gasket 10 with a larger positioning size can be fixed by selecting the connecting screw hole 110 on the circle with a larger radius, and the gasket 10 with a smaller positioning size can be fixed by selecting the connecting screw hole 110 on the circle with a smaller radius, so that the range of use of the device is further expanded.

[0037] In an embodiment, three positioning assemblies 200 are provided. In this embodiment, the adjacent positioning assemblies 200 are 120 degrees, forming a triangular support for the middle gasket 10, which can improve the positioning stability of the gasket 10 and is beneficial to the subsequent electric riveting machining of the holder 20.

[0038] In an embodiment, the side of the sliding groove 2111 close to the platform 100 is provided with a flange 2113, and the connecting bolt 230 is screwed into the connecting screw hole 110 to make the guide piece 220 abut above the flange 2113. In this embodiment, the flange 2113 is provided, and when the positioning assembly 200 is moved to the appropriate position, the connecting bolt 230 is rotated to make the guide piece 220 abut above the flange 2113, which can further improve the stability of the connection of the positioning assembly 200.
