Gauging ring type separable part size detection device

Abstract

The invention provides a ring gauge type separable part size detection device, comprising a bottom plate and a detection working surface arranged on the bottom plate. The detection working surface is formed by detection parts symmetrically arranged on four corners of the bottom plate; each detection part comprises a guide keyway on the bottom plate; keys on the lower parts of guide plates are in slideable fit respectively with the guide keyways; the outer end of each guide plate is connected with a screw handle; the screw parts of the screw handles respectively match inner threads of bracketsfixed on the bottom plate; positioning blocks are respectively fixed on the guide plates; four positioning blocks are in a circle to form the detection working surface; the lower part of the outer end of each guide plate is provided with a stop head pushing against a positioning surface of the bottom plate.

Description

technical field The invention relates to a ring-gauge type separable part size detection device, which is used for detecting the outer dimensions of parts, especially shaft parts, in the process of processing. Background technique At present, enterprises use ring gauges or snap gauges for the detection of shaft parts, that is, a special measuring tool for sizing, and its general structure is fixed and inseparable. It is divided into two types: open end and non-stop end, and the open end and non-stop end need to be used together. When in use, if the open end of the ring gauge can pass through smoothly, but the stop end cannot pass, the size of the shaft part to be inspected is qualified; on the contrary, if the pass end cannot pass through the part, or the stop end passes through the part, the tested part is unqualified. In the use of ring gauges, it is required that the operation should not be tilted, otherwise the parts to be inspected may be stuck and cannot be taken out....

AI Technical Summary

Problems solved by technology

In actual production, it is very easy for the parts to be inspected to be stuck in the ring gauge during the inspection due to the out-of-tolerance processing of the size, or the parts will be stuck even if the size is qualified and the operation is slightly improper.

And for some precision parts, if the upper and lower sides cannot be directly touched by hand, it will be difficult to remove during inspection. If the high-precision surface of the damaged part is forcibly removed, it will cause heavy losses.
