Abstract

The invention discloses an image measuring head and an image measuring system used for a numerical control milling machine, and the image measuring head and the image measuring system are simple in structural design and are relatively low in cost. The image measuring head can be conveniently and quickly fixed to a main shaft like a tool used for the numerical control milling machine, so that on-position measuring is realized. Moreover, the tool and the measuring head are convenient and quick to replace. Meanwhile, the image measuring head and the image measuring system are high in measuring speed and are beneficial to improving the production efficiency. The measured data can be used as compensation basis of a next workpiece, so that precision consistency of different processed workpieces is improved. More importantly, the image measuring head and the image measuring system can be matched with each shaft of the numerical control milling machine to move, so that geometric quantity measuring for a plurality of processing surfaces of a complex processing part can be realized.

Description

technical field [0001] The invention relates to the measurement field of a numerically controlled milling machine, in particular to an image measuring head and an image measuring system for in-situ measurement of a numerically controlled milling machine. Background technique [0002] In the machining process, geometric measurement is an indispensable and important link. CNC milling machines (including machining centers) are widely used in mechanical processing, and three-coordinate measuring machines are important geometric measurement equipment. Both have similar mechanical structures, both use the Cartesian coordinate system, and both use high-precision position feedback components such as grating rulers. They are the same in action execution and opposite to each other in the direction of information conversion. Moreover, it is generally believed that the accuracy of the machining machine is an order of magnitude higher than that of the machined parts, and the accuracy of...
