Adjustable saddle-shaped ring gauge

Abstract

Disclosed in the invention is an adjustable saddle-shaped ring gauge. The adjustable saddle-shaped ring gauge comprises a saddle-shaped ring gauge skeleton, wherein the arc of the inner surface of the ring gauge skeleton matches an arc of an outer surface of a standard plug gauge manufactured according to a product taper requirement. Detection holes are formed in two end of one side of the ring gauge skeleton; and dial indicators are installed in the detection holes, can move in the detection holes and are fixed by a gauge fixed bolt. According to the invention, after calibration with the standard plug gauge, detection can be carried out; the operation is simple; measurement data are provided and the measurement precision is improved; and the practical production demand is satisfied. Because the dial indicators can be used for adjusting the matching degree of the inner surface of the ring gauge skeleton and the plug gauge, problems that the traditional saddle-shaped ring gauge is discarded as useless when not matching the standard plug gauge and the usage is affected because of deformation of a saddle-shaped ring gauge due to an environment temperature or other factors can be solved, so that the rejection rate of the saddle-shaped ring gauge is reduced substantially and the using cost of saddle-shaped ring gauge detection is saved.

Description

technical field [0001] The invention relates to a saddle ring gauge, in particular to an adjustable saddle ring gauge, and belongs to the technical field of taper measuring and checking tools. Background technique [0002] The saddle ring gauge is a special inspection tool for measuring the taper of the product. The structure of the existing saddle ring gauge is as follows: figure 1 As shown, it is a rigid workpiece in the shape of a saddle. The method of use is to first coat the surface of the product to be tested with red lead powder, then buckle the saddle ring gauge on the surface of the product and take it off. The product can be judged by observing the wiping marks on the surface of the product. Whether the taper meets the requirements. Therefore, the existing saddle ring gauge is a kind of comparative measuring tool, which requires high manufacturing accuracy, but the specific value cannot be measured when measuring the taper. It is only judged by human experience, a...

AI Technical Summary

Problems solved by technology

Therefore, the existing saddle ring gauge must be frequently inspected and measured during production and use, which brings a lot of inconvenience to production; due to the structural characteristics of the saddle ring gauge, the scrap rate is very high in the calibration and testing process, and the scrap rate in practical applications It can reach 60-70%. At the same time, the structure of the saddle ring gauge is easily affected by the use environment, resulting in deformation or damage. The scrap rate can reach 20-40% when the test is due
