A combined teaching aid for mechanical design courses

Abstract

A machine design course combined teaching aid disclosed by the present invention comprises a teaching aid grillage, supporting legs are arranged at the lower end of the teaching aid grillage, and a rectangular groove is arranged on the teaching aid grillage. A sliding plate is arranged at the inner side of the rectangular groove, a fixing and connecting groove is arranged on the sliding plate, anda movable installing plate is arranged in the rectangular groove. Sliding fastening bases are arranged at the two ends of the movable installing plate, are in slip snap joint with the sliding plate and are equipped with the connecting holes. Two parallelly arranged installing slotted holes are arranged on the movable installing plate, the movable installing plate is connected with an adjustable shaft base via the installing slotted holes, and a driving device installing plate parallel with the rectangular groove is arranged at the lower end of the rectangular groove and is equipped with two parallelly arranged installing through holes. The machine design course combined teaching aid of the present invention is stable in structure, good in teaching effect and strong in operability, is flexible and varied, is convenient to adjust, can realize the assembly and usage of the design material objects of the reducers and the installation requirements of different transmission series, different shafts and different gears, and satisfies the current usage requirements.

Description

technical field [0001] The invention relates to a teaching tool, in particular to a combined teaching tool for mechanical design courses. Background technique [0002] Mechanical design, conceive, analyze and calculate the working principle, structure, motion mode, force and energy transmission mode, material, shape and size of each part, lubrication method, etc. of the machine according to the requirements of use, and transform them into specific descriptions The work process upon which manufacture is based. [0003] Mechanical design is an important part of mechanical engineering, the first step in mechanical production, and the most important factor determining mechanical performance. The goal of mechanical design is to design the best machinery under various limited conditions (such as materials, processing capabilities, theoretical knowledge and calculation methods, etc.), that is, to make optimal designs. Optimal design needs to comprehensively consider many requirem...

Problems solved by technology

[0005] Now when we study mechanical design, we usually learn from books. In the process of learning mechanical design, we need to learn a variety of transmission mechanisms, among which the reducer is one of our important learning contents. Now Although there are also many teaching aids for learning the design of gear reducers, these teaching aids are fixed now, and can only realize the design of the more traditional two-stage and three-stage reducers, and the number of transmission stages, the distribution of gears and the selection of shafts They are all fixed, and the teaching is relatively rigid, which cannot meet the current use requirements
