Processing and detecting method for end face deep annular groove

Abstract

The invention provides a processing and detecting method for an end face deep annular groove. The method comprises the steps of processing the large diameter of the annular groove capable of being detected according to the design pattern dimensional tolerance, and determining the control range of the small diameter size; determining a set of gauge size precision distribution according to the groove width size tolerance zone; enabling gauges to stretch into the groove according to the sequence from small to large, and detecting the actual groove width size; calculating the small diameter size, and adjusting the feed amount according to the actual small diameter size for processing; and processing and detecting the small diameter size in this way. Equipment needed by the method is simple in structure, operation is reliable and facilitated, an operator and an inspector can control the processing course and the inspection result more visually, accurately and reliably, the processing difficulty can be reduced, the production efficiency and the product quality are improved, and the requirement for batch production is met.

Description

technical field [0001] The invention relates to the field of mechanical processing and detection, in particular to a method for processing and detecting an annular groove. Background technique [0002] The deep annular groove on the end face is widely used in many equipment structural parts. The cross-sectional view shows an L-shaped hook groove with a flat bottom. The two diameters of the end face annular groove are assembly matching dimensions. Processing and testing methods are particularly important. The groove width is controlled by the large and small diameters, and the maximum diameter of the ring groove is Small diameter is The distance between the bottom of the groove and the end face is 130mm, and the length-to-diameter ratio of the diameter of the cutter bar for processing the ring groove is greater than 18.5, so it is difficult to process and detect. For the structure, see image 3 . Affected by the structural space position, the small diameter cannot be dir...

AI Technical Summary

Problems solved by technology

[0003] The main problems of this method are: the size of the processing process cannot be monitored and controlled, the processing process is relatively blind, the flexibility and controllability are poor, the requirements for operator skills are high, and the production efficiency is difficult to improve; the size tolerance zone of the go and stop gauges is small (0.025mm ), there are springback and instability factors in the elongation processing of the cutter bar, it is difficult to control the dimensional accuracy, the efficiency is low, and there is a certain quality risk, which has seriously restricted the production efficiency and batch demand

At the same time, the final inspection result of the product has no specific value, and can only judge whether it is qualified or not. The actual status data of the product is incomplete, and big data statistics and analysis cannot be performed.
