Problems solved by technology

When the above four detection devices or detection systems are working, the cam must be removed from the processing equipment first, and then the detection is carried out. If the detection fails, the cam needs to be put back into the processing equipment and repositioned to continue processing, resulting in work Efficiency is greatly reduced, and the objects of detection are all the outer contours of plane disc cams
[0007] Chinese patent documents CN101434053B (patent application No. 20081020397.4), CN101561250B (patent application No. 200910052043.3) and CN101259596A (patent application No. 200810023391.3) respectively disclose an "automatic positioning and online measurement method and device for cam noncircular grinding", "large Size cam non-circular grinding intelligent positioning and online measurement method" and "a kind of numerical control cam grinding machine", the first of the three documents described in the online measurement belongs to the contact measurement, the measurement accuracy is low, and the contact measurement process May cause damage to the machined cam surface and the measuring head is subject to wear
In the second document, the online measurement belongs to laser image measurement, the detection device is complicated, and the manufacturing and maintenance costs are high
The first two types of cam profile grinding devices and detection methods mentioned above are only used for the outer profile of flat disc cams
The third document is that it can only be processed, and the cam still needs to be removed from the equipment to be tested by another testing equipment.

Abstract

The invention discloses a control method for a planar conjugate cam contour detecting and grinding device. The technical point is that when a grinding wheel grinding head of a grinding mechanism of a grinding controlling and detecting device performs grinding on an outer contour of a planar conjugate cam, a second laser measuring head of a cam inner contour detection device performs reciprocating movement in the axial direction of the plane conjugate cam and measures a contour line in the axial direction of the inner contour of the plane conjugate cam; when the grinding wheel grinding head of the grinding mechanism of the grinding controlling and detecting device performs grinding on the inner contour of the planar conjugate cam, a first laser measuring head of a cam outer contour detection device performs reciprocating movement in the axial direction of the plane conjugate cam and measures a contour line in the axial direction of the outer contour of the plane conjugate cam; and when the cam rotates by a circle, the grinding control device can simultaneously perform on-line detection on the contour size of one of the inner contour and the outer contour of the plane conjugate cam in the circumferential direction and performs grinding on the other contour of the inner contour and the outer contour of the plane conjugate cam.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a control method for detecting and grinding a plane conjugate cam profile using a plane conjugate cam profile detection and grinding device. Background technique [0002] The cam mechanism is a transmission mechanism mainly composed of a cam, a follower and a frame. According to different forms, cams are usually divided into three types: disc cams, moving cams and cylindrical cams. Disc cams are further divided into disc-shaped inner cams and disc-shaped outer cams. Because disc-shaped inner cams are rarely used, the disc-shaped cams usually referred to as disc-shaped cams refer to disc-shaped outer cams. According to the difference of the movement trajectory of the follower, the cam is divided into a plane cam and a space cam. Plane cam means that the motion plane of the cam and the motion plane of the follower are parallel or coincident with each other. Disc cams and m...
