Constant-acceleration and constant-deceleration curve assembly of cam profile line generator

Abstract

The invention relates to a constant-acceleration and constant-deceleration curve assembly of a cam profile line generator. The constant-acceleration and constant-deceleration curve assembly of the cam profile line generator comprises a rack, a cam sliding rail and a lower guide rail which are mounted on the rack and are perpendicular to each other, wherein a movable cam is in sliding fit with the cam sliding rail through a sliding block; a first rack is fixed on the movable cam and is meshed with a first gear of a first motor which is fixed on the rack; a cam slot is formed in the movable cam; a first front travel switch is arranged on the front end of the cam slot; a first rear travel switch is arranged at the rear end of the cam slot; the cam groove is connected with one end of a pushing rod through a cam roller; a travel adjusting rotary plate comprises an upper plate structure and a lower plate structure; the upper plate and the lower plate can mutually rotate after a fastening part is released; the lower plate of the travel adjusting plate is connected with the other end of the pushing rod; the bottom of the lower plate is fixed on a lower sliding block; the lower sliding block slides on a lower guide rail; the upper plate of the travel adjusting rotary plate is fixed to an upper sliding block; the upper sliding block slides on an upper guide rail. The constant-acceleration and constant-deceleration curve teaching of the cam is simple and clear, convenient and intuitionistic, and is strong in demonstration property.

Description

technical field [0001] The invention relates to a teaching instrument—a cam profile generator, in particular to a constant acceleration and deceleration curve component of the cam profile generator. Background technique [0002] The cam mechanism plays an important role in the mechanical design. The cam can make the follower move in any desired way only by designing the appropriate cam profile, and the structure is simple, compact and easy to design. Therefore, it is widely used in automatic machine tools and light industrial machinery. , textile machinery, printing machinery, food machinery, packaging machinery and mechatronics products are widely used; the main function of the cam mechanism is to make the follower complete various complex movements according to the work requirements, including linear movement, swing and constant speed movement and non-uniform motion. [0003] The cam mechanism is generally a high-level mechanism composed of three components: the cam, the ...

Problems solved by technology

[0006] In the current teaching research, the abstract graphic method and the difficult analytical method have always been the best choice in the teaching process. No matter what kind of curve it is for, use these two methods to summarize the acceleration and deceleration curves such as cams It is not easy because for mechanical subjects, simple written expression and oral description are not conducive to learners to achieve a good learning effect. Therefore, in order to achieve a better teaching effect, the acceleration and deceleration curves of the cam In the process of understanding, it is necessary to add a more intuitive, operable and demonstrative auxiliary teaching instrument to help learners have a deeper understanding of the characteristics of the acceleration and deceleration curves of cams, etc. more simple, clear, convenient and intuitive
