Abstract

The invention provides a disc cam demonstration instrument. The disc cam demonstration instrument comprises a base plate (1), an element installed on the front face of the base plate and an element installed on the rear face of the base plate. The element installed on the front face of the base plate and the element installed on the rear face of the base plate mainly comprise a horizontal movement component, a vertical movement component, a rotation component, horizontal and vertical movement components and pinnacle push rods (28), a roller push rod (29), a flat-faced push rod (30), a drawing pen combination (31), a push rod movement rule curve template (32), a cam template (33), push rod movement rule curve drawing paper (34) and cam contour drawing paper (35). According to use purposes, different combinations exist. The disc cam demonstration instrument can help students to better understand the mutual relation between the cam contour shape and the push rod movement rule, is suitable for various push rod forms such as the pinnacle push rods, the flat-faced push rod, the roller push rod and the like and suitable or push rod alignment and bias occasions, covers most content of college disc cam teaching, and is visual and capable of being remembered, the learning interest of students can be induced, and the teaching efficiency of classes can be improved.

Description

technical field [0001] The invention relates to a disc cam demonstrator for demonstrating the relationship between the profile of a disc cam and the motion law curve of a push rod, and is a teaching instrument for a university mechanical principle course. Background technique [0002] Cams and cam mechanisms are widely used in mechanical design, automated production equipment and other fields. Cam teaching is the most basic teaching content for undergraduate mechanical majors, and it is also the knowledge that mechanical undergraduates must master. At present, the courses of mechanical principles in universities are basically multimedia teaching. When most teachers talk about cam mechanisms, they only explain them theoretically or demonstrate them on the screen, and rarely use experimental equipment to demonstrate them. The disc cam demonstrator of the present invention covers most of the teaching content of disc cams in colleges, can help students better understand the rel...
