Abstract

The invention discloses a vacuum pump piston ring finish machining process, and relates to the technical field of machining. The vacuum pump piston ring finish machining process is completed through cooperation of a vacuum pump piston ring finish machining device, the vacuum pump piston ring finish machining device comprises a base horizontally fixed to the ground, supporting legs erected at the top end of the base are symmetrically arranged on the two sides of the top end of the base, a horizontally-fixed top supporting plate is arranged at the top ends of the supporting legs on the two sides, the two ends of the top supporting plate are fixedly connected with the top ends of the supporting legs on the two sides, a downwards-through shaft hole is formed in the middle of the top end of thetop supporting plate, and an annular clamping groove is formed in the inner wall of the shaft hole of the top supporting plate. According to the vacuum pump piston ring finish machining process, through cooperation of outer clamping and inner clamping, the outer wall of a vacuum pump piston ring and the inner wall of the vacuum pump piston ring are ground in the one-time clamping process of the vacuum pump piston ring, and the grinding practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a finishing process for a vacuum pump piston ring. Background technique [0002] A vacuum pump refers to a device or device that uses mechanical, physical, chemical or physicochemical methods to evacuate the evacuated container to obtain a vacuum. Generally speaking, a vacuum pump is a device that uses various methods to improve, generate and maintain vacuum in a certain closed space. [0003] The existing piston ring grinding device disclosed in Patent No. CN201711044338.7 includes a motor and a mounting frame. The bottom of the mounting frame is fixedly connected to the motor through a plurality of brackets. The top of the rotating shaft is fixedly connected with a disk, the edge of the bottom of the disk is fixedly connected with a second connecting rod, and the right side wall of the second connecting rod is fixedly connected with one end of the first spring.
