Abstract

The invention relates to a multifunctional cam teaching tool and belongs to the field of teaching appliances. The multifunctional cam mechanism teaching tool is mainly composed of a slide block, a slide rail, a slide block extending plate, a slide rail bracket, a roller driven piece, a guide rod, a sliding chute rod, a cam, a main shaft, a base, a screw knob and a clamp. The slide rail with baffles arranged at two ends thereof is provided with the slide block, and a long baffle is arranged at one side of the slide rail. The lower end of the slide rail bracket is fixedly connected to the clamp, and the clamp is sleeved on the main shaft and is wholly fixed on the base. The slide block extending plate is fixedly connected to the upper end of the slide block, and a rectangular through groove and a round through groove are formed in the slide block extending plate. A shaft sleeve is arranged at one end of the sliding chute rod and is in clearance fit with the main shaft. The cam is fixed on the main shaft through a mounting hole. The multifunctional cam mechanism teaching tool realizes integrated demonstration of most cam teaching contents, meanwhile can lighten teaching burden of a teacher and improve teaching effects efficiently as innovative functions for demonstrating an adjustable driven piece, an adjustable and readable eccentric distance, an inversion-method designed cam profile principle and the like are added, and makes up the vacancy of the existing integrated cam teaching tools.

Description

Technical field

[0001] A multifunctional cam mechanism teaching aid belongs to the field of teaching instruments, and specifically relates to a teaching aid used for mechanical courses such as "mechanics". Background technique

[0002] In the teaching of "Mechanical Principles", "Mechanical Design Fundamentals", "Mechanical Fundamentals" and other mechanical courses, the important and difficult contents of the cam mechanism include the movement law of the cam follower, the working characteristics of the eccentric cam and the design of the cam by the reversal method The principle of contour curve, etc. However, the current cam teaching aids can only simply demonstrate the movement of the cam follower, the function is too single, the operability is not strong, and there are certain limitations in teaching adaptability. Summary of the invention

[0003] The patent of the present invention provides a multifunctional cam mechanism teaching aid, which can demonstrate the basic principl...
