Composite teaching tool of cam mechanism and demonstration control method thereof

Abstract

The invention discloses a composite teaching tool of a cam mechanism and a demonstration control method of the composite teaching tool. The teaching tool comprises a box body, the cam mechanism and a demonstration control system; the demonstration control system comprises a data acquiring module, a control processing unit and a display module; the composite teaching tool is characterized in that the displacement, speed, acceleration, pressure and other data of the teaching tool are acquired and converted into a characteristic curve pattern of a displaying module, and thereby teaching objects can intuitively and specifically know rational knowledge of composition structure, movement process and movement characteristics of the cam mechanism, and the consistency of teaching of various knowledge points of the cam mechanism in the teaching experience can be improved. The method comprises the steps of data acquiring, processing and displaying. According to the method, the quantifiable result of the movement characteristics of the teaching tool is intuitively displayed by an intelligentizing process, and thus the teaching object can reach the theory level by data comparison and analyzing, and as a result, the purpose of a probe test can be reached.

Description

technical field [0001] The invention relates to the teaching field, in particular to a cam mechanism compound teaching aid and a demonstration control method thereof. Background technique [0002] With the improvement of the country's requirements for the comprehensive quality of talents in the machinery industry, the requirements for mechanical courses in colleges and universities, especially basic courses such as mechanical principles and mechanical design, are also constantly increasing. As far as the current experimental teaching mode of mechanical principles is concerned, the explanation of theoretical basic knowledge is almost still in a blank state, especially the experimental teaching aids are still in the traditional "one object, one model" stage, which has been in line with the learning habits of contemporary college students. It is out of touch with the habit of thinking, and also contradicts the objective reality of the growing demand for talents in the machinery...

AI Technical Summary

Problems solved by technology

[0004] 1. Failure to properly resolve the relationship between the knowledge imparting of the cam mechanism and the cultivation of students' abilities, one-sided emphasis on knowledge imparting, and ignoring the internalization of knowledge into students' ability and quality; in experimental teaching, there are many verification experiments, but few exploratory experiments. The class did not allow students to enter the theoretical knowledge of the cam mechanism, nor did it stimulate the students' desire to explore the theoretical knowledge of the cam mechanism, and did not play the due role of experimental teaching;

[0005] 2. The experimental teaching of cam mechanism lacks systematization, and the phenomenon of fragmentation of various theoretical knowledge points is serious. There is no compound teaching aid that covers multiple knowledge levels of cam mechanism and unifies it into a macro knowledge system; at the same time, the experimental teaching of cam mechanism Separated from other practical teaching activities, ignoring the integration and coherence of cam mechanism knowledge, each practice link is independent of each other, and the overall design concept of cam mechanism is not emphasized in the whole teaching process;

[0006] 3. Due to the limitation of class hours, it is impossible to arrange more time for students to concentrate and synchronize experiments; while the traditional cam mechanism experiment teaching is difficult to carry out due to the constraints of the experimental site, experimental equipment, and experimental fun. Changes in knowledge paths and habits, traditional single-type cam mechanism teaching aids gradually withdraw from the teaching stage in the experimental class of cam mechanism mechanical principles
