Cam experiment teaching aid

Abstract

The invention discloses a cam experiment teaching aid which comprises a machine frame, a bidirectional cam set mechanism, a bidirectional push plate mechanism, a writing desk mechanism and a bottom transmission mechanism. The bidirectional cam set mechanism, the bidirectional push plate mechanism, the writing desk mechanism and the bottom transmission mechanism are arranged on the machine frame, and the bottom transmission mechanism controls the bidirectional cam set mechanism, the bidirectional push plate mechanism and the writing desk mechanism to move. The bidirectional cam set mechanism comprises an X-direction cam set, a Y-direction cam set, an X-direction cam shaft, a Y-direction cam shaft, an X-direction cam hoisting plate, a Y-direction cam hoisting plate, an X-direction pulley, a Y-direction pulley, an X-direction guide rod and a Y-direction guide rod. The writing desk mechanism comprises a work table, a flange linear bearing, a pen clamp, a pen rod, a hoisting cam and a hoisting ejector pin. The work table is fixedly arranged on the machine frame through the flange linear bearing, and the pen clamp is arranged on the work table. The variable combined cam mechanism is adopted and combined with a multi-level adjusting and controlling method, basic knowledge points of a cam, characters and drawings of complex figures can be demonstrated, and a concept of plane two-dimensional coding is adopted so that the complex figures can be projected to a matrix.

Description

technical field [0001] The invention relates to a cam experiment teaching aid, which belongs to the field of teaching instruments. Background technique [0002] The application and research of the cam mechanism in our country has a history of many years, and the cam mechanism is widely used in automatic equipment such as packaging machinery and food machinery. However, compared with advanced countries, there is still a big gap in the research of cam mechanisms in my country, especially in vibration, processing and product development. [0003] On the other hand, although the cam mechanism is a necessary learning content of "Principles of Mechanics" in the courses of related majors in many colleges and universities, its explanation of the knowledge of the cam is relatively abstract. However, the existing cam experimental teaching aids can only simply demonstrate the movement of the cam follower, which has a single function, which limits the teaching content, and most of the ...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the abstraction of the knowledge of the cam mechanism in the existing course learning, the existing teaching aids have a single function, which limits the teaching content, and most of the teaching aids used for demonstration are integral machines, which cannot be disassembled and assembled, and the operability is not strong , which limits the students' ability to practice, etc., the present invention provides a cam experimental teaching aid with a combined variable cam mechanism and multi-level control function, which can be intuitively and vividly demonstrated by drawing characters and complex graphics. The basic knowledge points, the cam experimental teaching aid that enables students to establish interest in learning the cam mechanism
