Method for detecting wall thickness and wall thickness difference of bipyramid

Abstract

The invention discloses a method for detecting the wall thickness and the wall thickness difference of a bipyramid. The method comprises the following steps: S1, installing a measured piece; wherein alarge cone outer measuring rod and a large cone inner measuring rod of a large cone measuring assembly are arranged on the outer side and the inner side of the large cone surface of a bipyramid workpiece respectively; a small cone outer measuring rod and a small cone inner measuring rod of a small cone measuring assembly are arranged on the outer side and the inner side of the small cone surfaceof the bipyramid workpiece respectively; S2, setting parameters before measurement; S3, measuring the bipyramid workpiece: wherein the wall thickness data of the bipyramid workpiece at each measuringpoint is measured; and S4, processing and evaluating the obtained axial wall thickness and circumferential wall thickness data. The bipyramid wall thickness detection device can perform automatic detection, automatic data reading, automatic analysis, processing and evaluation, mistake-proofing protection, automatic storage and output on the wall thickness of the bipyramid, reduces the influence ofhuman factors on a measurement structure, greatly improves the measurement precision, is high in automation degree, and improves the detection work efficiency.

Description

technical field [0001] The invention belongs to the technical field of double cone wall thickness and wall thickness difference detection, and in particular relates to a double cone wall thickness and wall thickness difference detection method. Background technique [0002] At present, the wall thickness and wall thickness difference of double-cone workpieces are mostly measured by manual metering and mechanical special manual measuring devices. The measurement data is manually read and recorded, and the wall thickness is manually calculated, analyzed and evaluated. And the way of wall thickness difference, this kind of manual measurement device has a large gap in the moving track, the uniformity of the manual push measurement process is poor, the measurement method has a large human error, poor repeatability, and the original records of the test results are filled in manually. The efficiency is low, and it is difficult to meet the detection work of the double cone wall thic...
