Problems solved by technology
Since there are many angles to be talked about and the planes that make up the angles, and the three auxiliary planes are hypothetical planes, it is bound to be difficult for the teacher to teach the lecture and for the students to listen to the lecture.
Some students didn’t know much about turning tools and turning processing before, and their three-dimensional sense of space was poor, so it was even more difficult for them to listen to the class
Although some teachers use a turning tool or a turning tool model as a teaching aid in class, the teaching effect is still not satisfactory

The invention relates to a demonstration instrument for teaching purpose, in particular to a turning tool label angle demonstration instrument, which comprises a demonstration turning tool, a pedestal and a plug board group, wherein a bottom surface of the demonstration turning tool contacts the pedestal; the demonstration turning tool consists of a front turning tool body and a back turning toolbody, which are connected with each other via a connecting piece; the back turning tool body is provided with a locating device; the pedestal is provided with three jacks; the first jack and an orthographic projection of a main cutting blade of the demonstration turning tool on the pedestal are arranged in parallel; the second jack and the orthographic projection of a contact surface between the front turning tool body and the back turning tool body on the pedestal are arranged in parallel and in level; the third jack and the feeding direction of the demonstration turning tool are arranged inparallel; and the three jacks are provided with plug boards. Compared with the current technology, the turning tool label angle demonstration instrument materializes abstract space concept by inserting different plug boards into the jacks of a base plate while demonstrating different angles, so that the turning tool label angle demonstration instrument helps students to understand and get deep impression, and can achieve good teaching effect.
Description
Technical field: [0001] The invention relates to a teaching demonstration instrument, in particular to a turning tool marking angle demonstration instrument. Background technique: [0002] The marking angle of turning tools in the prior art is the basis for marking the angles of other metal cutting tools, and it is also the basis for the design, manufacture, sharpening and measurement of turning tools. Therefore, the marking angle of turning tools is the main content of the professional courses of mechanical engineering in colleges and universities. one. [0003] The cutting surfaces and cutting edges of turning tools are generally inclined to each other in space. In order to determine their positions in space, three auxiliary planes are assumed: the base plane, the cutting plane, and the orthogonal plane to form an orthogonal plane reference system. The angle marked by the turning tool is to place the turning tool in this orthogonal plane reference system, and define the a...
