Abstract

A universal grinding machine special for nuclear power bearing inner race machining comprises a machine tool base, a machine tool body, a hydraulic system, an electric control system and a servo system and further comprises electric spindles, spindle lifting mechanisms, a workpiece shaft, a grinding wheel dresser, a workpiece shifting mechanism, a support assembly, a mechanical arm, a magnetic pole, grinding wheels, a cutting liquid circulation system and a nuclear power bearing inner race. Two sets of the electric spindles and the spindle lifting mechanisms are provided and installed on the upper portion of the workpiece shifting mechanism, each electric spindle works independently and moves vertically through the corresponding spindle lifting mechanism, the grinding wheel is installed on the lower end portion of each electric spindle, and the electric spindle drives the grinding wheel to rotate. Under the premise that machining accuracy is ensured, time for replacing mechanical parts and adjusting machining size is saved, machining can be conducted continuously by simply replacing the magnetic pole, and machining efficiency can be effectively improved.

Description

technical field

[0001] The invention relates to a grinding machine, in particular to a special grinding machine for bearing processing. Background technique

[0002] In the process of machining the inner ring of nuclear power bearings, the numerical control grinding machine needs to replace some specific parts to achieve the purpose of processing due to the change of the outer ring model and shape size. The replacement process requires debugging and trial production, and the process is complicated and cumbersome.

[0003] Usually, when the existing CNC grinding machine is started to process the first qualified product, the inner ring of the bearing will be positioned to replace the equipment or parts that are more suitable for processing the outer ring. Rates will also vary.

[0004] At the same time, the following problems also arise: the adjustment is very difficult, because there are many parts that need to be manually adjusted when the CNC grinding machine replaces equi...
