Abstract

The invention provides a dynamic turning tool angle demonstration teaching aid, which at least comprises a fixed base, wherein a display unit, a vertical running unit and a horizontal running unit are arranged on the fixed base, and the display unit comprises a box, a turnover mechanism, a rotating mechanism, a display platform and a rotating plate; the turnover mechanism and the rotating mechanism are arranged in the box, and the box is fixedly arranged on the fixed base; the rotating plate is arranged at the top of the box and rotates on the box under the action of the rotating mechanism, and the display platform is connected with the rotating plate through hinges; the display platform can turn over by 90 degrees under the action of the turnover mechanism and the hinges. The dynamic turning tool angle demonstration teaching aid provided by the invention has the advantages of simple structure, easiness and convenience in operation, and visual expression, and the defects of the prior art are overcome. The dynamic turning tool angle demonstration teaching aid provided by the invention can be used for simulating the tool feed and the generation process of a turning tool section plane, and dynamically demonstrating various working angles of a turning tool.

Description

technical field [0001] The invention provides a turning tool teaching aid for dynamic demonstration of the tool angle, which is specifically used for dynamically demonstrating the definition of the tool angle of the turning tool in actual processing, and belongs to the technical field of teaching aids. Background technique [0002] The geometric angle of cutting tools is the focus and difficulty of learning "Metal Technology" for students majoring in machinery. The teacher generally takes the turning tool as an example to explain, and the main explanation includes the definition of the geometric elements of the cutting part of the tool, the reference coordinate plane of the tool, and the geometric angle of the cutting part of the tool. Because these definitions involve a very abstract reference system for tool work, and the content is obscure and abstract, teachers must use appropriate teaching models to ensure that students can grasp and understand this part of the content....
