Problems solved by technology

In related technologies, due to unbalanced cutting force, non-complete circles cannot be drilled, reamed or honed. Milling is theoretically feasible, but the precision and efficiency are low due to the small hole size and low tool linear speed.
Grinding with profiled wheels is also not possible
Although special processing methods such as wire electric discharge cutting can obtain high precision, the cost is high and the efficiency is low.

Abstract

The invention discloses a machining fixture and a machining method for a piston of a compressor and the compressor. The machining fixture for the piston of the compressor comprises a rack, a piston, a cutting piece, a first fixing part, a second fixing part and an auxiliary part; the cutting piece can be connected with the rack, and the first fixing part is adapted for fixing the piston; and the first fixing part can be connected with the rack, the second fixing part can be switched between the first position and the second position, the second fixing part can be connected with the rack, and the auxiliary part can be connected with the second fixing part. When the second fixing part is located at the first position, the auxiliary part abuts against the piston, and an installing groove is machined on the piston by the cutting piece; and when the second fixing part is located on the second position, the second fixing part drives the auxiliary part away from the piston. According to the machining tooling for the piston of the compressor, the situations that the precision is low and the piston is deformed due to unbalancing cutting force when the cutting piece cuts the piston directly can be avoided; and the machining tooling is simple, cost is low, and precision is high.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a processing tool for a piston of a compressor, a processing method and a compressor. Background technique [0002] During the normal operation of the compressor, the installation groove for installing the sliding vane on the piston slides relative to the tip of the sliding vane and needs to be sealed, so the accuracy of the installation groove is required to be high. In related technologies, due to unbalanced cutting force, non-complete circles cannot be drilled, reamed or honed. Milling is theoretically feasible, but the precision and efficiency are low due to the small hole size and low tool linear speed. It is also impossible to grind with a profiled grinding wheel. Although special processing methods such as wire electric discharge cutting can obtain high precision, the cost is high and the efficiency is low. Contents of the invention [0003] The present i...
