Problems solved by technology

This method requires both the piston and the tool to move, and the machining axis is perpendicular to the longitudinal axis of the piston. During machining, the verticality of the machining axis and the center position of the piston are required to be high, which makes the machining more demanding for the operator and increases the difficulty of manufacturing.

Abstract

A method for machining a slippe slot on a piston used for compressor of air conditioner features that the piston and cutting tool are relatively moving and one of them is doing a circumferential movement relatively to another on a single plane around a circle center which is a predefined point on a ball body with the cutting tool is rotating around its central line.

Description

technical field [0001] The present invention relates to a processing method of a piston installed in a compressor used in a vehicle air conditioner, more precisely, the present invention relates to a processing method of a sliding shoe receiving groove of a piston, that is, the piston slot is recessed relative to the wall spherical shape. Groove processing method. Background technique [0002] Common compressors include a cavity formed within the housing. A drive shaft is rotatably supported within the housing. A part of the housing is constituted by the cylinder block. The cylinder block has cylinder bores, each housing a piston. A swash plate is mounted on the drive shaft in the cavity and supported for integral rotation with the drive shaft. Each piston engages with a peripheral portion of the swash plate via a shoe. The rotary motion of the swash plate is converted into linear reciprocating motion of the piston. The reciprocating motion of...
