Embodiment Construction

[0023] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0024] See attached figure 1 , the present invention is composed of an electromechanical integrated power input system 1, a power split system 2, an output cam drawing system 3, and the like. The cam drawing system at the output end can be divided into a known cam drawing follower characteristic curve module A3 and a known follower curve drawing cam module B3. One working cycle of the present invention only needs the cam to rotate one circle, and the two steps of drawing the characteristic curve of the follower and drawing the cam can be completed.

[0025] See attached figure 1 , in the electromechanical integrated power input system, we use a low-speed motor 101, and realize the positive and negative rotation of the motor through an electromagnetic switch, so as to ensure that the moving parts can be reset accurately.

[0026] See attached figure ...

Abstract

The invention is mainly applied to science and engineering mechanical principle teaching of colleges and universities, belongs to the technical field of cam applications, teaching apparatuses and the like and mainly solves the problems of teaching planarizartion and experiment singularization. A mapping platform comprises mechanical and electrical integration power input system, a power distribution system and an output cam mapping system. The output cam mapping system can be divided into a known cam mapping driven part characteristic curve module and a known driven part curve mapping cam module. The cam mechanism driven part basic laws, the plane cam contour curve design and the cam motion characteristic curve analysis are emphasized. The power distribution system is formed by worm transmission, gear transmission, belt drive and gear and rack transmission. A work cycle of the output end cam mapping system can complete two steps of driven part characteristic curve mapping and cam mapping. By means of the mapping platform, student can master basic theories, basic knowledge and basic skills of mechanical principles and have mechanical motion scheme determination and analysis and mechanism design capacities preliminarily.

Description

technical field [0001] The invention is mainly used in the teaching of mechanical principles of science and engineering in colleges and universities, and belongs to the fields of cam application, teaching instrument technology and the like. Background technique [0002] The biggest advantage of the cam mechanism is that it can make the follower (push rod) obtain various expected motion laws, and it is convenient to work in coordination with other mechanisms, so it is widely used. The study of the cam mechanism is mainly the basic motion law of the follower in the cam mechanism and its combination design, the basic principle of the reversal method, the design method of the plane cam profile curve, the determination of the basic size of the cam mechanism and the force analysis of the cam mechanism, etc. [0003] Although many engineers have invested in the improvement, design and development of teaching aids, there is a lack of a new type of teaching aids that integrate physic...
