Description

Technical Field

[0001] The utility model belongs to the technical field of compressor parts processing equipment, and in particular relates to a welding positioning tool for a compressor shell. Background Art

[0002] P nut welding is an important process in compressor casing processing. This process requires welding two P nuts on the compressor casing, which are used for assembling temperature sensing package bracket, temperature sensing package, etc. in the later process to monitor the temperature of the compressor. P nut welding is to position the compressor casing through tooling and use medium-frequency resistance welding to weld the P nuts to the compressor casing.

[0003] The utility model patent with the publication number CN217371149U discloses a welding positioning tool for a compressor housing, including a welding machine body, a support seat arranged on a workbench and used to support the compressor housing, a mounting seat arranged on the welding machine body and located above the support seat, an inner electrode head arranged on the mounting seat and used to fit the welding pipe fitting, and an outer electrode head arranged on the welding machine body and located above the inner electrode head. When welding two nuts, the compressor housing needs to be manually pushed and then welded. The inner electrode arm is inserted into the compressor housing, and the outer electrode is driven downward by the cylinder for compression and discharge welding.

[0004] However, after the inner electrode of this solution is repaired at the end of its service life, its height becomes smaller. During welding, the welded compressor shell will be greatly deformed. When the deformation exceeds the standard, the inner electrode can no longer be used. After the outer electrode is repaired at the same time, its size is shortened, which needs to be compensated by adjusting the lower sensor of the cylinder. In daily production, it is necessary to conduct random inspections on the deformation of the processed compressor shell, which consumes a lot of labor costs and wastes a lot of electrode materials.
