Description

Technical Field

[0001] The invention relates to the technical field of speed reducer processing, and in particular to a processing tool. Background Art

[0002] The reducer is a device used in modern industrial systems to match the speed and transmit torque between the power supply equipment and the working machine or actuator. The structure of the reducer is mainly an independent component consisting of a gear transmission, a worm transmission, and a gear-worm transmission enclosed in a rigid housing. There are many types of commonly used reducers according to different usage occasions and usage requirements.

[0003] Generally, they can be divided into two categories according to their uses: general-purpose reducers and special-purpose reducers. Therefore, the housing of the reducer will also have various structural types. Therefore, when a reducer housing is mass-produced in industrial production, it must be cut and processed. However, the processing tools in the prior art are prone to wear and chip removal during use. In order to solve the above problems, the present application discloses a processing tool. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the invention discloses a machining tool.

[0005] To achieve the above-mentioned object, the present invention is implemented through the following technical solutions: a machining tool, comprising a tool handle and a tool body integrally formed with the tool handle;

[0006] The tool body consists of a first sub-body, a second sub-body and a third sub-body whose diameters gradually decrease from top to bottom. A first step portion, a second step portion and a third step portion are respectively provided on the top of the first sub-body, the second sub-body and the third sub-body. A plurality of special-shaped cutting portions extending into the third step portion are obliquely arranged on the first sub-body and the second sub-body.

[0007] Further preferably, the length of the shank is 50 mm and the diameter is 13 mm.

[0008] More preferably, the diameter of the first body is 20 mm, the diameter of the second body is 15 mm, and the diameter of the third body is 6 mm.

[0009] Further preferably, a 45° chamfer is provided at the end of the third body.

[0010] Further preferably, the end of the third sub-body is processed by hardening treatment.

[0011] Further preferably, the number of the special-shaped cutting parts is two, and the two special-shaped cutting parts are special-shaped cutting blades arranged opposite to each other.

[0012] Further preferably, the knife body is made of tungsten steel.

[0013] The present invention achieves the following beneficial effects:

[0014] The processing tool claimed to be protected in this application is not prone to wear and can achieve better chip removal when processing the reducer end cover. Compared with the processing tools on the market, it has a longer service life, reduces the production cost of the enterprise, and has a strong use value.

[0015] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures pointed out in the description and the drawings. BRIEF DESCRIPTION OF THE DRAWINGS
