Description

Technical field

[0001] The invention relates to a cam profile detection device and a detection method thereof. Background technique

[0002] Cam mechanisms are widely used in various automated machinery, precision instruments, automated control systems, etc. It is necessary to detect the cam with high precision and efficiency, and correctly process and evaluate its various errors, and feedback the quality information of the cam in a timely and fast manner. The traditional optical mechanical measuring instrument and manual data processing methods can no longer adapt to the wide range of cams. The use of automatic production lines is needed. With the rapid development of the automobile industry and engineering machinery and the continuous improvement of manufacturing technology, how to improve the detection accuracy and efficiency of cam processing accuracy is a technical problem to be solved in this field. Summary of the invention

[0003] The technical problem to be solved by th...
