Embodiment Construction

[0010] Embodiment of the present invention: a groove (3) is opened on the supporting plate (1), and the support surface of the supporting plate (1) in contact with the workpiece can be made into a slope or a horizontal plane. In order to make the stability more reliable during processing, it is better to place the The support surface of the supporting plate (1) in contact with the workpiece is made into a slope, the adjustable positioning block (2) is installed in the groove (3) through screws, and a ring positioning surface is made on the positioning block (2) (4), make the supporting surface of the supporting plate (1) perpendicular to the ring positioning surface (4) of the positioning block (2), and make the outer diameter of the ring positioning surface (4) smaller than the ring type parts to be processed (5) Outer circle diameter, make the inner circle diameter of the ring positioning surface (4) greater than the inner circle diameter of the ring type parts (5) to be proc...

Abstract

A technology and apparatus for machining the external circumference surface of ring workpiece features that said ring workpiece is installed on a supporting plate with locating blocks, a centerless grinder is used to abrase the external circumference surface by used for abrasive disc, and a guide roller is installed opposite the abrasive disc for driving said ring workpiece to rotate. Its advantage is high precision.

Description

Technical field: [0001] The invention relates to a processing method and device for processing the outer circle of a ring-like part by using a centerless grinder, and belongs to the technical field of outer-circle processing of the ring-like part. Background technique: [0002] The rotary compressor is the heart of the household air conditioner, and the ring parts (with various names, such as: roller, rotor, ring, piston, roller sleeve, etc.) are the core parts of the compressor. Because the compressor requires low noise and energy saving , environmental protection, high efficiency and long life, so the ring parts are required to have high hardness, high wear resistance, high position tolerance, dimensional accuracy and surface roughness. This has caused difficulties in the processing of such ring parts. The most critical requirement is that the perpendicularity of the outer circle of the ring to the end face is not greater than 3 μm, the cylindricity of the outer circle its...
