Three-coordinate measuring method and device for workpiece, equipment and storage medium

Abstract

The embodiment of the invention discloses a three-coordinate measuring method and device for a workpiece, equipment and a storage medium. The measurement method comprises the steps of irradiating a plurality of common measurement points of a first preset area on a supporting plate of a measurement platform to obtain a plurality of first coordinates of the plurality of common measurement points based on a first coordinate system, wherein the plurality of common measurement points have a plurality of second coordinates based on a second coordinate system of the measurement platform; determininga conversion relationship between the first coordinate system and the second coordinate system according to the plurality of first coordinates and the plurality of second coordinates; obtaining an initial coordinate of the workpiece based on the second coordinate system of the measurement platform through the conversion relationship; and performing three-coordinate measurement on the workpiece based on the initial coordinates to obtain measurement parameters of the workpiece in the second coordinate system. According to the embodiment of the invention, automation of three-coordinate measurement of different types of workpieces is realized.

Description

technical field [0001] Embodiments of the present invention relate to measurement technology, and in particular to a three-coordinate measurement method, device, equipment and storage medium of a workpiece. Background technique [0002] Three-coordinate inspection is a precision measurement method for inspecting workpieces. Widely used in machinery manufacturing, automobile industry and other modern industries. Three-coordinate measuring machine is one of the most effective ways to measure and obtain dimensional data, because it can replace multiple surface measurement tools and expensive combination gauges, and reduce the time required for complex measurement tasks from hours to minutes, which is Effects that cannot be achieved by other instruments. [0003] In the three-coordinate automatic inspection process, there are usually two methods for automatic measurement of parts. One is to manually align the detected parts first, so that the parts and three coordinates are i...

Problems solved by technology

[0004] The first method can solve the detection of various parts very well, but manual alignment is required before each detection, especially for batch parts, which is time-consuming and laborious

Although another method solves the problem of manual docking of parts, different parts need to use different positioning tools, which reduces the versatility of automatic detection
