Description

technical field [0001] The invention belongs to the technical field of tool rest performance detection, and in particular relates to an online detection device for numerically controlled tool rest performance parameters. Background technique [0002] The performance parameter detection of the CNC tool post is a necessary step for the tool post manufacturer before the product leaves the factory, and it is also one of the important means of precision testing in the tool post reliability test. On-line detection of the performance parameters during the operation of the tool holder, and observation of changes in performance parameters can help to detect and eliminate faults in time, and even predict faults. The tool post itself contains multiple tool positions, and the tool change action needs to be repeated continuously during the working process. During the tool change process, the tool post will be in a state of rotating motion. The above characteristics make it difficult to ...
