Problems solved by technology
[0003] In the teaching of engineering drawing and other courses, it is very important to use teaching aids to explain the three-view, but the commonly used teaching aids are often difficult to intuitively explain the three-view projection principle and express the internal outline of the view model, which makes it difficult for beginners to learn
The reason is that engineering drawing requires students to have strong spatial imagination, and the existing teaching aids cannot observe the outline of the studied model well and form an intuitive three-view, so that students can establish three-dimensional and two-dimensional drawings. perception and concept

The invention discloses a three-view projection teaching apparatus and belongs to the field of engineering drawing teaching aids. The three-view projection teaching apparatus is characterized by comprising a projector fixing frame, a model holding platform is arranged in the projector fixing frame, an X-direction driving device is mounted on the projector fixing frame, a Y-direction driving device is mounted on the X-direction driving device, a Z-direction driving device is mounted on the Y-direction driving device, a projecting device is mounted on the Z-direction driving device, and a main-view curtain, a side-view curtain and a top-view curtain are mounted on the front, the lateral side and the bottom of the projector fixing frame respectively. The three-view projection teaching apparatus has functions of directly observing internal and external contour lines of a researched model and visually forming three views, and students can learn mutual transformation between three-dimensional and two-dimensional diagrams in mechanical drawing according to projection lines.
Description
Technical field: [0001] The invention relates to a three-view projection teaching instrument, which belongs to the technical field of engineering drawing teaching equipment. Background technique: [0002] With the development of technology, the traditional teaching mode - "blackboard and chalk" has been gradually replaced by multimedia teaching and various modern teaching aids. Teaching aids are the general term for all kinds of utensils and utensils used in the teaching process for the relevant courses or teaching content objectives. Modern teaching aids enable students to understand the teaching content intuitively and visually, making teaching easier and more relaxing. According to the characteristics of teaching objectives and teaching objects, through teaching design, rationally select teaching aids, make full use of modern teaching media, and organically combine with traditional teaching methods, participate in the whole teaching process together, form a reasonable te...
