Turning tool model for teaching demonstration

Abstract

The invention relates to a turning tool model for teaching demonstration. A tool bit is divided into a primary cutting blade part, a secondary cutting blade part, a tool nose part and a tool bit connecting part on a primary section and a secondary section, wherein the primary cutting blade part is arranged on the secondary section of the tool bit by a connecting piece; the secondary cutting blade part is arranged on the primary section of the tool bit by a connecting piece; the tool nose part is arranged between the main cutting blade part and the secondary cutting blade part and fixedly connected with the primary cutting blade part and the secondary cutting blade part by the connecting piece, respectively; the tool bit connecting part is provided with a first insertion hole on the primary section; a first slide rod is arranged in the first insertion hole in a through manner; one end of the first slide rod is hinged with the secondary cutting blade part; the tool bit connecting part is provided with a second insertion hole on the secondary section; a second slide rod is arranged in the second insertion hole in a through manner; one end of the second slide rod is hinged with the main cutting blade part. The turning tool model concretizes the abstract space concept so as to be convenient for the students to memorize, thereby remarkably improving the teaching effects.

Description

technical field [0001] The invention relates to the technical field of metal cutting teaching, in particular to a turning tool model used for teaching demonstration. Background technique [0002] A turning tool is a tool for turning that has one cutting portion. Turning tool is one of the most widely used tools in cutting. The function of the turning tool is to remove the excess metal layer on the workpiece. The cutting part of the general turning tool is mainly composed of the rake face, the main flank face, the auxiliary flank face, the main cutting edge, the auxiliary cutting edge and the tool nose angle. The combination of the cutting part of the turning tool and the tool body (that is, the clamping part) mainly includes integral type, welding type, mechanical clamping type and welding-mechanical clamping type. [0003] Tool angle is the main factor affecting cutting efficiency and processing quality, and it is also a key factor. Therefore, when designing, manufacturin...
