[0016] Please refer to Figure 1-2, the present utility model provides a technical solution: an auxiliary part for welding, including a part body 1, a positioning cylinder 2, a gas-dissipating channel 3, a ventilation hole 5 and a connection hole 6. The part body 1 is of an overall cylindrical structure. The positioning cylinder 2 is arranged at the center position of the end face of the part body 1. A connection hole 6 is arranged at the center of the other end face of the part body 1. A plurality of groups of the gas-dissipating channel 3 and the ventilation hole 5 are respectively arranged on both end faces of the part body 1. Among them, the gas-dissipating channel 3 and the positioning cylinder 2 are on the same end face, and the ventilation hole 5 and the connection hole 6 are on the same end face. The gas-dissipating channel 3 and the ventilation hole 5 are interconnected.

[0017] Furthermore, the connection hole 6 is arranged as a threaded hole, and the connection hole 6 is installed on the fixed column through a threaded structure. The positioning cylinder 2 is aligned with the through hole of the pressure chamber housing on the accumulator. The central axes of the positioning cylinder 2, the connection hole 6 and the clamping tool for the joint to be welded coincide with each other.

[0018] Furthermore, the ventilation holes 5 are arranged in an annular array around the connection hole 6, and the ventilation holes 5 are arranged as circular through holes.

[0019] Furthermore, the gas-dissipating channel 3 is arranged as a strip-shaped sunk groove, and the gas-dissipating channel 3 is arranged in an annular array around the positioning cylinder 2. Communication holes are arranged in the gas-dissipating channel 3, and the communication holes are arranged in one-to-one correspondence with the ventilation holes 5 and are interconnected.

One group of mounting surfaces 4 is of a flat structure, and the other group of mounting surfaces 4 is of a concave arc-shaped surface structure.

[0021] Working principle: The part body 1 is fixedly installed on the fixed column through the connection hole 6 on one side. The fixed column provides an installation position. The other side of the part body 1 is docked with the through hole of the pressure chamber housing on the accumulator through the positioning cylinder 2. The joint to be welded is clamped by a clamping tool. The central axis of the clamping tool coincides with the central axis of the fixed column.
