Nuclear Power Bearing Ring Processing Special Superfinishing Machine

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.

[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. During the replacement process, debugging and trial production are required, and the process is complicated and cumbersome.

[0003] On pages 19-22 of the 4th issue of "Bearing" in 2011, the title was disclosed: Bearing Ring Grinding and Superfinishing Machine, author: Lu Hongdao, recorded in paragraphs 3-5 of this document The configuration of the grinding superfinishing production line, its specific technical plan includes the following content. When the CNC superfinishing machine is started to process the first qualified product, it will carry out the positioning of the nuclear power bearing ring and replace the equipment parts that are more suitable for processing this ring. According to Operators have different understandings of the equipment, and the scrap rate in the trial production process will also have certain differences; the defects of the above technical solutions are: 1. It is very difficult to adjust: because the CNC superfinishing machine needs to change the processing model There are many parts to be manually adjusted, which is cumbersome and complicated; 2. The adjustment time is very long: due to the high requirements for the experience of the processing personnel, it will take a very long time for novices to master it. , High error rate: Because of the experience and ability of the processing personnel, in the test process of judging whether the adjustment is good, it will cause an increase in the scrapped amount of the processed workpiece
