Abstract

The invention provides a go/no go gauge fast-checking dovetail size of brake blade and manufacturing method thereof, the go/no go gauge comprises a gauge body, a dovetail through-end chute and a dovetail not-go-end chute; the dovetail through-end chute is arranged on one side of the gauge body; the dovetail not-go-end chute is arranged on the other side of the gauge body; the dovetail through-endchute and the dovetail not-go-end chute are symmetrically arranged on both sides of the gauge body, and the dovetail through-end chute and the dovetail not-go-end chute are trapezoid-shaped slots which are concave toward the gauge body; the go/no go gauge provided by the invention can greatly improve the detection efficiency, reduce the measurement error, and greatly reduce the production controlcost and the detection cost of the universal dovetail steel backing; moreover, the go/no go gauge is easy to be carried, has high wear resistance, is convenient for operators to use and can ensure thedimensional accuracy after being used for a long time, so as to effectively guarantee the long-time detection quality of the product.

Description

technical field [0001] The invention belongs to the technical field of brake dovetail dimension inspection, and in particular relates to a go-no-go gauge for quickly inspecting the dovetail size of a brake disc and a manufacturing method thereof. Background technique [0002] The dovetail size measurement of the dovetail general-purpose powder metallurgy brake pads for EMUs with a speed of 160-350 kilometers per hour and above is relatively cumbersome; the measurement tools specifically include dovetail width, dovetail height and dovetail angle; there are many measurement items and the angle It is difficult to measure accurately; and the dovetail size can only be judged whether it meets the requirements after taking the average value of multiple measurements. The work efficiency is low and it cannot directly reflect the qualification of the dovetail. [0003] Using existing measuring tools to measure the dovetail of the brake pads is costly and inefficient, and it is difficu...
