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 knowle

Example Embodiment

[0038] The embodiments of the present invention will be further described below in conjunction with the drawings.

[0039] See attached figure 1 , The present invention mainly includes five parts; a virtual restraint mechanism unit, a one-degree-of-freedom mechanism unit, a two-degree-of-freedom mechanism unit, a high-pair low-generation unit of a plane mechanism, and a power split unit. The five units are fixed on the bottom plate.

[0040] See attached figure 2 , The power split unit includes: motor 1 (101), coupling 1 (102), support base A1 (103), support base A2 (104), long shaft 1 (105), short shaft 1 (106), Timing pulley 1 (107), timing pulley 2 (108), timing belt (109), support seat A3 (110), bearing seat 1 (111), support seat A4 (112), timing pulley 3 (113) , Support seat A5 (114), long axis 2 (115). The motor 1 (101) is a 12V DC motor, which is fixed on the bottom plate (6) by a support base A1 (103). One end of the stub shaft 1 (106) is fixedly connected to the output sha

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aims at solving the problems that experiment modes in the mechanical subject experiment teaching are single and outdated, be understood through physical model static displaying, and teaching aid assisted matched structures are complicated, large in size and cannot perform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.
