specific Embodiment approach 1

[0051] Specific implementation mode 1: In this implementation mode, the thin-walled bearing outer ring turning processing method is specifically carried out according to the following steps:

[0052] 1. Roughly turn the left end face of the rough billet, rough turn the outer raceway, and perform chamfering treatment to obtain the workpiece;

[0053] 2. Roughly turn the right end face of the workpiece obtained in step 1, rough turn the outer diameter, and perform chamfering treatment;

[0054] 3. Use the water immersion ultrasonic method to perform flaw detection on the workpiece processed in step 2;

[0055] 4. The left end face of the workpiece processed in step 3, the outer raceway of the thin car, and the inner slope of the car are processed by removing the acute angle of the slope, and then the outer corner is chamfered;

Abstract

A thin-walled bearing outer ring turning processing method and a thin-walled bearing outer ring end face groove symmetry measurement method, the invention relates to the field of thin-walled bearing processing and measurement. The invention aims to solve the technical problems that the existing thin-walled bearings are easily deformed during processing and the efficiency of measuring the symmetry of the end face grooves is low. Turning processing methods: rough turning, water immersion ultrasonic flaw detection, fine turning, light decoration, medium temperature stress relief, uniform grinding of two planes, soft grinding of outer diameter, final turning of raceway, inner corner chamfering, end face groove milling, deburring, light decoration, high temperature Stress relief, heat treatment, finishing, grinding. Measurement method of the symmetry of the outer ring end face groove: install the measuring device, measure h1 and h2, the absolute value of the difference between the two is the symmetry of the outer diameter centerline of the narrow groove, and measure the wide groove in the same way. The method of the invention reduces the deformation amount during processing of the thin-walled bearing, improves the processing accuracy, and replaces the three-coordinate measurement with the method of measuring the symmetry of the end surface groove, thereby improving the production efficiency. The invention is used for turning thin-walled bearings and measuring the symmetry of the end face grooves of the thin-walled bearings.

Description

technical field [0001] The invention relates to the field of thin-walled bearing processing and measurement. Background technique [0002] Thin-walled bearings are designed for narrow structural space of the main engine or special performance requirements. When the ratio of the outer diameter to the inner diameter of the bearing is less than or equal to 1.143, it is called a thin-walled bearing. The biggest difficulty in processing thin-walled bearings is that the ring is easily deformed during the processing, and the deformation is caused by clamping the outer diameter or inner diameter, and the processing method is not appropriate, and the problem of deformation has not been effectively solved. [0003] The outer ring of the thin-walled bearing is actually an elastic body. Although the machined surface of the outer ring is rounded by the car, due to elastic deformation, the outer ring returns to its original shape after the claws are released, that is, the shape and positi...
