Abstract

The invention discloses a link mechanism based multifunctional teaching aid which comprises a main teaching aid driving mechanism, a slider speed describing mechanism, a cam curve describing mechanism, a link speed describing mechanism and a motion certainty analysis mechanism, the main teaching aid driving mechanism, the slider speed describing mechanism and the cam curve describing mechanism are arranged on a main teaching aid support, and the main teaching aid support comprises a horizontal base plate and a rectangular frame fixed on one side of the horizontal base plate. Knowledge points of various mechanical principles are represented through a plurality of link mechanisms arranged on the main teaching support, teaching effect can be improved, and classroom teaching is enabled to be more targeted and applicable.

Description

technical field [0001] The invention relates to a teaching tool, in particular to a connecting rod mechanism capable of realizing the cam curve forming process, the qualitative analysis of the speed of the slider in the crank slider mechanism, the qualitative analysis of the connecting rod speed in the connecting rod mechanism, and the analysis of the deterministic conditions of motion And other multi-functional teaching tools. Background technique [0002] At present, there are few or even no teaching aids in the classroom teaching of mechanical courses. When students understand and master the relevant knowledge of such courses, they mostly rely on imagination, and it is difficult to achieve the effect of classroom teaching. The use of mechanical teaching aids has greatly accelerated the process of students understanding and mastering classroom knowledge, and has broad application prospects. The knowledge points of mechanical courses are closely related. If there is a set ...
