Abstract

The invention provides a device for detecting cam profiles, which has the advantages of simple structure, high detection precision and higher efficiency. The device comprises a numerical control turntable, a linear motor, a laser measuring head, a grating scale displacement sensor, an encoder and an industrial personal computer, wherein the numerical control turntable is used for driving the cam to horizontally and coaxially rotate around a vertical mandrel; the linear motor is horizontally arranged on one side of the numerical control turntable; the laser measuring head is arranged on the active cell of the linear motor and at one side of the cam; the grating scale displacement sensor is used for measuring the horizontal displacement of the active cell; the encoder is used for detecting the rotation angle of the cam; and the industrial personal computer controls the numerical control turntable and the linear motor to act and obtains the outer profile data of the cam according to datameasured by the laser measuring head, the grating scale displacement sensor and the encoder.

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...
