Description

Technical Field

[0001] The utility model belongs to the technical field of piston compressor shell processing, in particular to an auxiliary tool for assembling the piston compressor shell. Background Art

[0002] A piston compressor is a type of compressor that relies on the reciprocating motion of a piston to pressurize and transport gas. It is a positive displacement compressor, also known as a "reciprocating piston compressor" or "reciprocating compressor". It is mainly composed of a working chamber, transmission parts, a fuselage and auxiliary parts. The working chamber is directly used to compress the gas and is composed of a cylinder, cylinder liner, air valve, packing, piston and piston rod. When processing the cylinder shell, the connecting parts on its surface need to be assembled and welded. When assembling and welding, most users will place the shell on a placement rack, and then assemble and weld the connecting parts on its surface to facilitate the installation of other parts.

[0003] At present, when processing piston compressor housings, most of the connecting parts on their surfaces are assembled and welded. Since most piston compressor housings are cylindrical, the compressor housing may deflect during assembly and welding, which may cause the connecting parts to shift during assembly and welding. Therefore, there is a need for an auxiliary tooling for assembling the piston compressor housing. The piston compressor housing can be limited by a limiting structure to avoid deflection of the piston compressor housing during assembly and welding, thereby improving the stability of the piston compressor housing during assembly.

[0007] Preferably, two symmetrical reinforcement plates are fixedly connected to the back side of the inner cavity of the mounting frame, and the reinforcement plates are triangular in shape.

[0008] Preferably, the top of the lifting frame one is higher than the top of the lifting frame two, and the bottom of the limiting rod is fixedly connected to two symmetrical pads.

[0009] Preferably, the support frame is T-shaped, and three longitudinal support plates are fixedly connected to the back of the mounting frame.

[0010] The beneficial effects of the utility model are:

[0011] 1. The utility model starts the motor to make the threaded rod and the lifting frame move in a threaded manner. The lifting frame drives the piston compressor housing to move upward through the limit rod, and separates from the top of the lifting frame.
