Device for measuring annular groove depth

Abstract

The invention relates to a device for detecting the depth of an annular groove. The device for detecting the depth of the annular groove comprises a magnetometer base, an adjusting device and a measuring device. The magnetic gauge stand is attracted to a lathe Z-axis ram through the magnetic force of the magnetic gauge stand. The adjusting device is installed on the magnetometer base. The measuring device is installed on the adjusting device. The measuring device can rotate at will; the device is low in production cost, stable in operation, easy to maintain, long in service life and wide in application range. According to the invention, the defect of insufficient measurement precision grade in the prior art is overcome; measurement errors and randomness are large. The invention provides adevice capable of accurately measuring the groove depth in cooperation with a numerical control vertical lathe. The device is simple in structure, wide in application range, convenient to operate, efficient and capable of achieving the measurement tolerance grade of 0.001-0.01, the problem that measurement is not accurate when the depth of the inner circular ring groove and the depth of the outercircular ring groove are measured through a vertical numerical control lathe is solved, and the rejection rate is reduced in the machining process.

Description

technical field [0001] The invention belongs to the technical field of processing, and in particular relates to a device for measuring the depth of a ring groove. Background technique [0002] In the process of machining, parts with ring grooves and cross-sectional grooves are usually encountered, and the groove depth accuracy of these parts is high and the grooves are relatively narrow. Usually, the detection method of this kind of groove considers the use of depth gauge or vernier caliper for measurement, but for narrow grooves, the feet of vernier caliper and depth ruler are relatively large, which is not suitable for measuring narrow grooves, and the measurement tolerance zone of vernier caliper and depth gauge is 0.1, unable to meet the requirement of workpiece accuracy grade less than 0.01. For CNC vertical lathes, the measuring table can be used to measure the groove depth of the ring groove, but only the size on the central busbar of the workbench is closest to the ...
