Abstract

The invention provides a cam profile detection system based on a direct driving motor, and the cam profile detection system is simple in structure and high in detection precision and efficiency. The system comprises the direct driving motor, a mandrel, a feed screw nut pair, a laser measurement head, a grating ruler displacement sensor, a circular grating and an industrial personal computer, wherein the mandrel is coaxially and fixedly arranged on the rotor of the direct driving motor and is used for driving a cam to coaxially rotate synchronously; the feed screw nut pair is horizontally arranged at one side of the cam; the laser measurement head is arranged on the movable nut of the feed screw nut pair; the grating ruler displacement sensor is used for measuring the horizontal displacement amount of the movable nut; the circular grating is arranged in the fixed seat of the direct driving motor and is used for detecting the rotation angle of the rotor; and the industrial personal computer controls actions of the direct driving motor and the feed screw nut pair, and obtains outer profile data of the cam according to data obtained by the laser measurement head, the grating ruler displacement sensor and the circular grating.

Description

[0001] This application is a divisional application, the application number of the original application: 201110114560.6, the application date: 2011.05.04, the title of the invention: a cam profile detection system based on a direct drive motor. technical field

[0002] The invention relates to a cam profile detection system based on a direct drive motor and a detection method thereof. Background technique

[0003] Cam mechanisms are widely used in various automatic machinery, precision instruments, automatic control systems, etc. To achieve high-precision, high-efficiency detection of cams, correct processing and evaluation of its various errors, and timely and rapid feedback of cam quality information, traditional optical-mechanical measuring instruments and manual data processing methods can no longer adapt to the wide range of cams. The need for automatic line production is adopted. With the rapid development of the automobile industry, engineering machinery, etc. and ...
