A Combined Teaching Aid of Plane Link Mechanism

Abstract

The invention discloses a planar linkage mechanism combined teaching aid. The teaching aid comprises a machine frame part, a motion part and a power part. The machine frame part comprises a base frame, a sliding frame and a supporting frame. The motion part comprises a connecting rod unit, a connector and an auxiliary movable frame. The motion part comprises a motor frame and a simple pneumatic system, wherein the motor frame is composed of a sliding frame, a motor supporting base, a motor, a small belt pulley, a synchronous belt, a supporting frame, a large belt pulley, a belt pulley shaft, a flexible coupler and a transmission coupler. Through free splicing of all the parts, motion demonstration of various planar linkage mechanisms is realized, and the effects of realizing design, motion demonstration, characteristic research and the like of different planar linkage mechanisms on different teaching aids are better achieved. The teaching aid realizes knowledge point reappearance of various mechanical principles, can improve the teaching effect, and enables classroom teaching to have high pertinence and high applicability.

Description

technical field [0001] The invention relates to a mechanical teaching tool, in particular to a combined teaching tool for realizing a planar four-bar mechanism, a crank slider mechanism, and superposition of a planar mechanism by a planar linkage mechanism. Background technique [0002] The mechanical principle course is a basic course of mechanical professional technology. The task is to let students understand the basic knowledge of common mechanisms and common parts, and then learn the complex design calculations of mechanisms. Understanding parts and mechanisms is an important link. How to let students quickly grasp the complex and abstract mechanism movement principles through the teacher's explanation, teaching aids are a good choice. The use of mechanical teaching aids greatly speeds up the process of students understanding and mastering classroom knowledge. The application prospect is broad. [0003] Linkage components have various motion forms, such as rotation, sw...

AI Technical Summary

Problems solved by technology

Intuition is one of the main teaching principles. Students need perceptual knowledge or experience as the basis to better grasp book knowledge, especially the mechanical knowledge of crank-rocker mechanism, double crank mechanism, double rocker mechanism and crank-slider mechanism. If you simply use explanations and drawing methods, you can't fully explain and understand it, which will not only increase the teaching burden of teachers, but also affect the learning effect of students.

[0004] At present, there are many domestic teaching materials used to demonstrate the planar linkage mechanism, but the design is relatively old-fashioned and clumsy, the mechanism is too simple, and there is no change. change is limited
