Abstract

The invention provides an inductance type wireless ball rod instrument. The inductance type wireless ball rod instrument is mainly composed of a ball rod instrument main machine, a center support assembly, a center cup assembly and a set ball assembly. The ball rod instrument main machine comprises an inductance measuring head assembly, a battery assembly, a circuit board assembly and a ball rod instrument main body. A wireless measuring system composed of the ball rod instrument main machine, the center support assembly and the center cup assembly is used for comprehensively detecting the precision of a CNC machine tool motion shaft. The instrument is simple to operate, high in precision, low in cost and capable of quickly detecting the precision of the CNC machine tool motion axis.

Description

technical field [0001] The invention relates to the field of error measurement of circular motion track of a numerical control machine tool. Background technique [0002] CNC machine tools play a very important role in modern processing technology. The accuracy of machine tools determines the accuracy of machined parts. If it can be determined that the accuracy of the machine tool meets the requirements of the index before processing the parts, the generation of scrap products can be avoided, thereby avoiding large economic losses. Laser interferometers can be used to detect and compensate the accuracy of machine tool motion axes, but it takes a long time. In actual production, processing workers only need to know whether the accuracy of the machine tool meets the requirements, and it is not necessary to compensate the accuracy of the machine tool. Therefore, it is necessary to have a device for quickly detecting the accuracy of the machine tool. The ballbar is used to co...
