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 a kind of "automatic positioning and online measurement method and device for cam noncircular grinding", "big 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 detecting grinding device which is characterized by comprising a grinding mechanism and an online detecting device. When a grinding wheel grinding head of the grinding mechanism of the detecting grinding device carries out grinding processing of the outline of a plane conjugate cam, a second laser detecting head of the inner contour detecting device of the cam reciprocates along the axial direction of the plane conjugate cam and measures the outline line of the inner contour of the plane conjugate cam along the axial direction. When the grinding wheel grinding head carries out the grinding processing of the inner contour of the plane conjugate cam, a first laser detecting head of the outline detecting device of the cam reciprocates along the axial direction of the plane conjugate cam and measures the outline line of the outline of the plane conjugate cam along the axial direction. When the cam rotates one circle, the detecting grinding device is capable of carrying out online detection of the size of one outline of the inner contour and the outline of the plane conjugate cam on the circumferential direction and grinding the other outline of the inner and external contours of the plane conjugate cam simultaneously.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a detection and grinding device for detecting and grinding cam contours in cam processing equipment. 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 moving cams belong to plane cams, while s...
