The invention discloses a view projection demonstrator, comprising a turn plate a, a turn plate b and a turn plate c, wherein the turn plate a, the turn plate b and the turn plate c are coaxially connected by a shaft; a bearing a is installed between the turn plate a and the turn plate b; a sliding rod penetrates through the middle part of the turn plate a along the diameter direction; the surface, close to the turn plate b, of the turn plate a is provided with a plurality of pits; two collision beads are installed on the surface, close to the turn plate a, of the turn plate b; the positions of the two collision beads are corresponding to these of the pits; a model placing platform is installed on the other surface of the turn plate b; a bearing b is installed between the other surface of the turn plate a and the turn plate c; one end of the sliding rod is sleeved with a sliding sleeve b capable of sliding along the axial direction; the sliding sleeve b is fixedly connected to a projection plate; the other end of the sliding rod is sleeved with a sliding sleeve a capable of sliding along the axial direction; a light source is fixedly connected to the sliding sleeve a. The view projection demonstrator can well demonstrate multi-dimensional projection views of lines, surfaces, basic shapes, combined shapes and cut bodies.
Description
technical field [0001] The invention belongs to the technical field of teaching equipment, and in particular relates to a view projection demonstrator. Background technique [0002] The engineering graphics course is a professional and technical basic course that engineering students must take. Mastering the methods and skills of reading and drawing engineering drawings is not only the basis for engineering students to study follow-up professional courses and carry out graduation projects, but also the basic skills necessary for engineering and technical work in the future. With the rapid development of modern mechanical engineering science and technology, higher requirements are put forward for the drawing level of engineers. Therefore, for engineering students, learning the course "Engineering Graphics Basics" well is the most basic requirement for becoming a qualified engineering technician. [0003] At present, many engineering majors offer engineering drawing courses....
