Ultra-precision machine special for machining nuclear power bearing rings

Abstract

An ultra-precision machine special for machining nuclear power bearing rings comprises a machine tool base, a lathe bed, a hydraulic system, an electronic control system, a servo system, electric main shafts, rotary head lifting mechanisms, a workpiece shaft, rotary head movable rods, sliding blocks, a workpiece translational mechanism, a supporting component, a magnetic pole, a rotary eccentric wheel, the nuclear power bearing rings, rotary head slide ways and oil stone clamps. The number of the electric main shafts and the number of the rotary head lifting mechanisms are both two sets, and the electric main shafts and the rotary head lifting mechanisms are all arranged above the workpiece translational mechanism. Each set of electric main shaft independently works and moves up and down through a corresponding rotary head lifting mechanism. The rotary eccentric wheel is arranged on the lower end portions of the electric main shafts, and the electric main shafts drive the rotary eccentric wheel to rotate. The ultra-precision machine is used for more conveniently and quickly machining the nuclear power bearing rings, on the premise of guaranteeing machining precision, time for replacing mechanical parts and debugging the machining size in the prior art can be saved, machining can be continued as long as the magnetic pole is replaced, and machining efficiency is effectively improved.

Description

technical field [0001] The invention relates to a superfinishing machine, in particular to a special superfinishing machine for bearing processing. Background technique [0002] In the process of machining nuclear power bearing rings by CNC superfinishing machines, some specific parts need to be replaced to achieve the purpose of processing due to changes in the type and shape of the rings. The replacement process requires debugging and trial production, and the process is complicated and cumbersome. [0003] The technical solution of the existing technology is that when the CNC superfinishing machine is started to process the first qualified product, the nuclear power bearing ring will be positioned and replaced, which is more in line with the equipment parts for processing this ring. According to the different understanding of the equipment by the operators, try The scrap rate that occurs in the production process will also have certain differences; the disadvantages of th...
