Problems solved by technology

The model used in the current teaching is often a large-sized turning tool teaching model. This model can only reflect one angle of one tool type. Since its type and its angle are limited to one type, it cannot be used for turning tool types. It is often difficult for students to truly grasp and understand the definition of tool angle and its angle change, which leads to students encountering changes in tool types or tool angles in production practice. When the models used in the classroom teaching are different, it is still impossible to correctly analyze the angle of the tool, which leads to the inability to sharpen the tool correctly, and it is difficult to apply what you have learned

Embodiment Construction

[0024] Such as Figure 6 As shown, a combined turning tool teaching aid includes a cutter body and a base plate 8, and the cutter body and the base plate 8 are connected together in a detachable manner. The cutter body includes a cutter head 1 and a handle 2, and the cutter head 1 and the The knife handles 2 are connected in a detachable manner.

[0025] Such as figure 1 and figure 2 As shown, the cutter head 1 is divided into a first cutter head assembly block 12, a second cutter head assembly block 13, a third cutter head assembly block 14, and a fourth cutter head assembly block along the XZ reference plane 4, YZ reference plane 5 and XY reference plane 6. Cutter head assembly block 15, the fifth cutter head assembly block 12', the sixth cutter head assembly block 13', the seventh cutter head assembly block 14', the eighth cutter head assembly block 15', between the above-mentioned cutter head assembly blocks To be detachably connected together, a detachably connected t...

Abstract

The invention discloses a combined turning tool teaching aid, which comprises a tool body and a base plate, wherein the tool body and the base plate are detachably connected with each other. The tool body comprises a tool bit and a tool handle, which are detachably connected with each other. The tool bit is formed by detachably connecting at least two tool bit combination block. Various turning tools and turning tool geometric angles can be demonstrated by means of assembly and disassembly to rapidly improve spatial imagination for students and enable the students to understand and master contents of courses.

Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to a turning tool teaching aid which can be flexibly disassembled and combined. Background technique [0002] The geometrical angle of cutting tool is the key and difficult point of learning for students majoring in metal cutting. In the lecture, the teacher mainly takes the turning tool as an example to explain. The explanation includes more than ten definitions including 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. The concept of space is strong and the content is obscure and abstract. Therefore, the teacher must When explaining, it is only with the help of appropriate teaching models that students can master and understand this part of the content. The model used in the current teaching is often a large-sized turning tool teaching model. This model can only refle...
