Cascade mold inspection tool

Abstract

The invention discloses a cascade mold inspection tool. The inspection tool comprises a go gauge and a no-go gauge used cooperatively with the go gauge, wherein the go gauge comprises a holding part Aand a detection part A fixedly connected with a bottom end of the holding part A; the holding part A and the detection part A are integrally formed; the no-go gauge comprises a holding part B and a detection part B fixedly connected with a bottom end of the holding part B; and the holding part B and the detection part B are integrally formed. The cascade mold inspection tool disclosed by the invention has the beneficial effects of simple structure, easy manufacturing, low cost, high detection efficiency, accurate precision control, short detection time and simple determination standard.

Description

technical field [0001] The invention relates to the field of high-pressure casting, and more specifically, the invention relates to a stepped mold inspection tool. Background technique [0002] With the development of the economy, more and more cities have established rail transit systems, including high-speed rail, light rail, subway, etc. Elevators are also added at the track site to facilitate people's travel. For elevators, they are usually divided into two specifications: "box elevator" and "escalator". [0003] When the escalator is running, people stand on the steps, the large plane is the "tread surface", and the arc surface at the front end of the foot is the "kick surface". Due to the different sizes of the tread teeth and the different side slopes, conventional measuring tools (caliper / Micrometer) cannot be detected. The previous method of tread tooth detection requires upper three-dimensional detection. Usually, the tooth processing of the tread mold core start...

Problems solved by technology

[0003] When the escalator is running, people stand on the steps, the large plane is the "tread surface", and the arc surface at the front end of the foot is the "kick surface". Due to the different sizes of the tread teeth and the different side slopes, conventional measuring tools (caliper / Micrometer) cannot be detected. The previous method of tread tooth detection requires upper three-dimensional detection. Usually, the tooth processing of the tread mold core starts from CNC and ends with polishing. It needs to go through 6 processes: CNC numerical control machining→CMM three-dimensional detection→EDM electric Pulse processing → CMM three-dimensional inspection → polishing → CMM three-dimensional inspection, according to statistics, the inspection time for the entire process from CNC machining to polishing is about 3 hours, including CNC dismantling of workpieces, and CMM on the machine twice, if it cannot be processed at one time If it is qualified, it needs to be machined many times. Due to the high precision of the teeth, the amount of processing needs to be fine-tuned, which takes longer. In view of this, it is necessary to develop a stepped mold inspection tool to solve the above problems
