Connecting rod module of piston compressor

Abstract

The invention discloses a connecting rod module of a piston compressor and the piston compressor using the connecting rod module. The connecting rod module comprises a first connecting rod, a second connecting rod and a positioning piece; a first shaft hole matched with a piston pin is formed in a first end of the first connecting rod, and a convex head is arranged at a second end; a second shaft hole matched with a crankshaft is formed in a first end of the second connecting rod, and a groove is formed in a second end; the convex head is a T-shaped convex head; the groove is a T-shaped groove matched with the T-shaped convex head; and when the T-shaped convex head is clamped in the T-shaped groove, the positioning piece is embedded in a gap between the T-shaped convex head and the T-shaped groove, so that the T-shaped convex head is tightly connected with the T-shaped groove. By use of the connecting rod module of the piston compressor, provided by the invention, the problems of complex structure, difficult mold molding and troublesome assembly in a traditional integrated connecting rod are overcome; and compared with a traditional split connecting rod module, the connecting rod module of the piston compressor also has the advantages of simpler structure, easiness in mold molding and more convenience for assembly.

Description

technical field [0001] The invention relates to components of a compressor, in particular to a piston compressor connecting rod assembly and a piston compressor using the connecting rod assembly. Background technique [0002] The structure of the existing compact crankshaft-connecting rod piston compressor is as follows: figure 1 As shown, since the piston compressor adopts a bearing hole and cylinder hole integrated frame 1, a U-shaped groove 1a is often provided at the end of the cylinder hole of the frame 1 to install the connecting rod 5 on the crankshaft 4 and the piston 2. Due to the existence of the U-shaped groove, the force on the tool of the cylinder hole is uneven during processing, and the thermal deformation is asymmetric during operation. At the same time, the piston stroke is limited when the product model is expanded. [0003] In order to solve the above problems, various structures have emerged, some of which use a split structure that divides the connectin...
