Abstract

The invention provides a manual type plane cam contour collecting experiment teaching device and a plane cam contour collecting experiment method. With the technical scheme, the high-degree matching between plane cams and driven parts can be conveniently realized, the plane cams with different contours and various driven parts can be conveniently replaced, and the biasing distance of the driven parts can be adjusted according to the demands. Through a handle and a connecting rod mechanism, the movement at fixed angle towards one direction of a ratchet mechanism is driven, then the cam is driven to perform intermittent movement, the interval angle of the intermittent movement of the cam can be realized by replacing ratchet wheels with different tooth numbers, and meanwhile, by changing theposition of a crank bracket in a sliding chute, the accurate intermittence angle after replacement of the ratchet wheels is guaranteed. Through a pointer on the cam driven part and scales on a guide path of the driven part, the displacement of the driven part can be conveniently acquired, and with the experiment device, the manual detection for the plane cam contour can be realized.

Description

technical field [0001] The invention belongs to the technical field of mechanical principles and mechanisms, and in particular relates to a cam mechanism, in particular to a manual plane cam profile acquisition experimental teaching device and an experimental method. Background technique [0002] Cam mechanism is one of the most commonly used mechanisms in mechanical equipment. Because of its simple and compact structure, and the follower can achieve predetermined regular changes, it is often widely used in various automatic control equipment. [0003] The theoretical content of the cam mechanism is relatively abstract, and it is difficult for students to learn, especially when it involves the design and analysis of the cam profile and the comprehensive application of the cam mechanism. [0004] At present, domestic cam teaching equipment integrates motor drive and sensor collection into one, combined with computer for quantitative or qualitative test and analysis. The comp...
