Embodiment Construction

[0039] The present invention is described in detail with reference to the drawings and embodiments.

[0040] The technical scheme of the present invention is to design a piston pin of a hermetic compressor, and a fixed joint groove 32 is opened on one side of the body 31 of the piston pin 30, and the fixed joint pin 40 is inserted into the fixed joint groove 32, and the piston 20 and the connecting rod 50 are connected in conjunction with each other.

[0041] The method of manufacturing the piston pin of this hermetic compressor is to process according to the following steps:

[0042] The first is the cutting process, where the material is cut into sections;

[0043] Then there is a forging process, forging the above-mentioned segmented material to increase its strength, and forging a fixed joint groove on the outer side of each segment of the material during the forging process;

[0044] Then it is a heat treatment process, and the above-mentioned forged material is subject...

Abstract

The present invention discloses a piston pin of closed compressor and its making method. One side of piston pin self body is equipped with a fixing combination groove, a fixing combination pin can be inserted into the fixing combination groove, so that said inserted combination of fixing combination pin and fixing combination groove can make the piston be coupled with connecting bar. Its production method of piston pin includes the following steps: cutting material, forging cut block material to form fixing combination groove on its external one side, then heat treatment and finally completion operation. Its production procedure is simple and its product accuracy is high.

Description

technical field [0001] The present invention relates to a hermetic compressor, and in particular relates to a piston pin connecting a connecting rod and a piston and a method of manufacturing the same. Background technique [0002] The internal structure of a general hermetic compressor is as follows: figure 1 As shown, the upper container 1 t and the lower container 1 b constitute an airtight container 1 , and a frame 2 is provided inside the airtight container 1 . A stator 3 is fixed on the frame 2, and the frame 2 is supported inside the airtight container 1 by a spring 2S. [0003] A crankshaft 5 is provided through the center of the frame 2 . A rotor 4 is integrally provided on the crankshaft 5 , and the crankshaft 5 rotates together through the electromagnetic interaction between the rotor 4 and the stator 3 . An eccentric shaft 5 b is provided at an upper end of the curved shaft 5 , and the eccentric shaft 5 b is provided eccentrically with respect to the rotation ...
