Multiple pose measuring machine tail end coordinate identification method based on actual material reference

Abstract

Disclosed is a multiple pose measuring machine tail end coordinate identification method based on an actual material reference. The multiple pose measuring machine tail end coordinate identification method based on the actual material reference includes: firstly, clamping the actual material reference on a rotary table of a multiple pose measuring machine and fixing the actual material reference; adjusting the actual material reference and the rotary table so as to enable the actual material reference and the rotary table to be concentric, and using a sensor of the multiple pose measuring machine to perform hierarchical scanning on the actual material reference; measuring a standard cylinder surface 4 and a standard cylinder surface 5 of the actual material reference during the scanning process, then figuring out a tail end coordinate of each section, and thereby obtaining a multiple pose measuring machine tail end coordinate. The multiple pose measuring machine tail end coordinate identification method based on the actual material reference uses the actual material reference clamped on the rotary table of the multiple pose measuring machine and an aligning function of the rotary table in combination with the hierarchical scanning on the actual material reference, performed by the sensor of the multiple pose measuring machine, figures out coordinate value through measuring software, and thereby obtains value of the multiple pose measuring machine tail end coordinate, achieves multiple pose measuring machine tail end coordinate positioning, and simultaneously has the advantages of being simple, low in cost, simple to use and the like.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing and detection, and in particular relates to a method for recognizing coordinates at the end of a multi-position and attitude measuring machine based on a physical reference. Background technique [0002] In the current measurement process of complex contours, the entire contour of the workpiece to be measured is often measured, and it is difficult to complete the overall measurement of complex curved surface workpieces through one posture. Usually, it is necessary to realize multi-pose measurement of the workpiece to be measured, and obtain surface information of different orientations of the workpiece at favorable angles or directions. In order to ensure the rationality and completeness of the measurement data, it is necessary to transform two or more pieces of data point clouds under different datums into the same datum. The laser tracker can be used to achieve accurate position...
