Method for mounting compressor piston and slipper into cylinder

Abstract

The invention relates to a method for putting the compressor piston and slipper into cylinder, while the traditional method has hard installment and easy abrasion of piston. The inventive method comprises: (1) putting the cylinder on a rotational disc; (2) putting the main axle inclined disc element above the cylinder with a distance between them; (3) rotating the inclined disc of main axle inclined disc element to make the maximum space between the cylinder and the inclined disc be able to contain mounted piston and rotating the cylinder disc to make one piston hole of it aim said maximum space; (4) mounting the piston and slipper on the highest point of inclined disc and loosening the inclined disc to make it recover to horizontal position, and the piston enters relative piston hole; (5) repeating the steps from (2)-(4), putting each piston into relative piston hole; (6) descending the main axle inclined disc element and the piston to be packed in the cylinder. The invention can reduce the mounting hardness and time with improved mounting quality.

Description

technical field [0001] This invention relates to the manufacture of compressors and, in particular, to the method of incorporating compressor pistons and shoes into cylinder blocks. Background technique [0002] The structure of the variable displacement compressor is as follows: figure 1 As shown, the core components in its body components include cylinder block 1, main shaft swash plate component 2, sliding shoe 3 and piston 4. Piston 4 is installed in the piston hole of cylinder block 1, and is connected on a swash plate that can change the angle within a certain range through sliding shoe 3. The drive plate fixed on the main shaft 1 (drive shaft) drives the swash plate to rotate, so that the piston 4 makes a reciprocating linear motion in the piston hole rhythmically to realize the suction and exhaust process of the compressor. [0003] In order to make the compressor have a smaller volume and weight while obtaining a maximum displacement, the assembly structure betwee...

AI Technical Summary

Problems solved by technology

[0005] 1. When installing the piston 4 and the sliding shoe 3 on the swash plate of the main shaft swash plate part 2, it is quite difficult to fully assemble the multiple pistons 4 and sliding shoes 3 because there is no outer ring to stop it, and it is easy to cause the assembled Piston and sliding shoes fall off

[0006] 2. The fit gap between the piston 4, the sliding shoe 3 and the swash plate is quite small, and it takes time and effort to assemble the piston sliding shoe to the swash plate without tools

Even if it can be installed, the piston will be scratched and shaved due to frequent adjustments

[0008] 4. The process operation is quite complicated, and it is easy to cause the piston to fall off and it is difficult to insert into the cylinder block, etc., which makes the assembly labor intensive and the production cycle is long, which cannot meet the needs of mass production at all.
