Comprehensive experiment teaching tool of hinge four-bar mechanism

Abstract

The invention relates to a comprehensive experiment teaching tool of a hinge four-bar mechanism. The comprehensive experiment teaching tool is characterized in that a crank rocker, double cranks, tworocker four-bar mechanisms and double slider-crank mechanisms (namely, two sets of slider-crank mechanisms) are ingeniously, perfectly and dynamically integrated, the whole teaching tool can randomlygallop upwards on a polished rod when in the double slider-crank state, and thus the practicability, interest and entertainment are realized. As a teaching tool, the device can lively and vividly demonstrate various changes of the four-bar mechanism to students, the effect of obtaining twofold results with half the effort is achieved, manual operation is available, automatic demonstration is alsoavailable, and the device is mainly used for classroom teaching, is novel, simple and diversified in structure, is strong in knowledge comprehensiveness, is easy to operate, and is low in fabricationcost.

Description

technical field [0001] The invention belongs to a mechanical teaching aid, in particular to a comprehensive experimental teaching aid of a hinged four-bar mechanism. Background technique [0002] Education is the foundation. As people pay more and more attention to education, the quality of education and teaching has become a problem that people pay more and more attention to. The hinged four-bar mechanism is a key point of the mechanical principle, but also a difficult point. How to make the boring and obscure part of the principle easy for students to understand? Mastering is a difficult problem for every teacher, but the current experimental teaching aids are old-fashioned and single, lacking in dynamics, and the principle of the hinged four-bar mechanism cannot be vividly demonstrated to students, which is completely inconsistent with the lively nature of contemporary college students. On the basis of three patents (a planetary gear screw nut gradient telescopic crank, ...
