Planar Mechanism Structure Teaching Analyzer

Abstract

The invention relates to a plane mechanism structure teaching analyzer and belongs to the technical field of teaching instruments. The analyzer aims at solving the problems that experiment modes in the mechanical subject experiment teaching are single and outdated, be understood through physical model static displaying, and teaching aid assisted matched structures are complicated, large in size and cannot perform in-class explanation through dynamic displaying and the like. The analyzer comprises five portions: a virtual restraint mechanism unit, a one-freedom mechanism unit, a two-freedom mechanism unit and a low-pair replacing high-pair unit of a plane mechanism and a power shunting unit. The five units are fixed on a bottom plate. By means of the analyzer, sports demonstration and exercise exploration are integrated, the analyzer can be brought into classes to performing teaching of plane mechanism composition, plane mechanism moving condition, mechanism freedom degree calculation methods, mechanism kinematic sketch drawing, mechanism structure analysis and the like.

Description

technical field [0001] The invention relates to a teaching aid, in particular to an instrument for analyzing and exploring the structure of a planar mechanism in mechanical subjects, belonging to the technical fields of planar mechanisms, mechanical subject teaching, and popular science education exhibitions. Background technique [0002] Teaching aids are special forms of teaching materials. Teachers' assistants and students' friends are one of the conditions for running a school. In addition, it also has a unique function, that is, in addition to supporting regular teaching activities, it is good at connecting with practice. Teachers and students use teaching aids in the teaching process not only to acquire knowledge, but also to exercise skills, so that they can "use hands and brains together". Therefore, it can be said that teaching aids are a necessary condition for promoting quality education and cultivating innovative spirit and practical ability. [0003] Teaching ...

AI Technical Summary

Problems solved by technology

However, this method can only feel the movement of the mechanism on a plane, and cannot allow students to go deep into the situation and directly explore the movement characteristics of the plane mechanism. The teaching effect is far inferior to that of physical teaching aids.

The second is to use a physical model, which has a better visual effect than image display, but the current commercially available and laboratory instruments may be static displays, such as mechanical teaching aid display cabinets. Many typical mechanisms are displayed in glass cabinets, and it is impossible to understand the movement. Regular, monotonous; or for dynamic display, such as the rod group analysis device, the explanation of knowledge is single, and the supporting electronic circuits and other supporting irrelevant structures are complex, bulky, and costly, and are not suitable for classroom demonstration instruments. At the same time, the integration of such devices Low, multiple devices are required to fully explain the knowledge of planar mechanisms, and the price / performance ratio is too low

[0005] Although people have made continuous improvements to this, the above-mentioned problems cannot be completely solved, which limits the innovation and promotion of teaching aids for mechanical subjects, and affects the effective development of mechanical subject teaching and the attractiveness and influence of related popular science exhibitions.
