Abstract

The utility model relates to a cutter comprises handle of a knife, thin wall sleeve, and the two integrated into one piece, handle of a knife and lathe hookup and carry out the centre gripping, thin wall sleeve be the hollow cylinder structure, on thin wall telescopic outer wall, the space more than two of evenly distributed's margin, two, margin and space alternate distribution. The margin acts as a cutting action and the neutral position is used to remove swarf.

Description

Cutting tool
Technical Field
The utility model relates to a cutter used in the metal cutting process.
Background
In the metal cutting process, corners and ridges are formed naturally. In general, the corners and edges are right-angled, also called sharp corners. The sharp corners are harmful, which not only affect the assembly of mechanical parts, the appearance and the scratch, but also easily generate stress concentration, cause fatigue failure and affect the service life of products.
In the field, the sharp corners are generally removed by manual grinding. The labor intensity of workers is high, the operation environment is severe, the production efficiency is low, dust damage is brought to the bodies of the workers, and meanwhile, the environment is easily polluted.
Disclosure of Invention
The utility model aims at providing a flexible cutter.
In order to realize the purpose, the technical scheme of the utility model is that: the cutter comprises a cutter handle and a thin-wall sleeve, wherein the cutter handle and the thin-wall sleeve are integrally formed, the cutter handle is connected with a machine tool and clamped, the thin-wall sleeve is of a hollow cylindrical structure, more than two cutting edges and more than two neutral positions are uniformly distributed on the outer wall of the thin-wall sleeve, the cutting edges and the neutral positions are alternately distributed, the cutting edges play a cutting role, and the neutral positions are used for removing cuttings.
Prior to use, the tool shank is first coupled to a power tool or machine tool.
During the use, electric tool or lathe drive the handle of a knife rotatory: then, the rotating thin-wall sleeve is contacted with the sharp corner part of the mechanical part; during the contact with mechanical parts, because the four blade zones are thin-walled structures, the four blade zones can be compressed and deformed, so that sharp corners can be removed easily, and smooth transition circular arcs can be formed.
The utility model discloses satisfy the needs that machine part got rid of the closed angle, have simple structure, the characteristics of the preparation of being convenient for.

Fig. 4 is a schematic view of the flexible cutting tool according to the present invention.
Detailed Description
The details and operation of the specific apparatus according to the present invention will be described in detail below with reference to the accompanying drawings.
The utility model relates to a cutter, including handle of a knife 1, thin wall sleeve 2, the two is integrated into one piece, handle of a knife 1 and lathe hookup and carry out the centre gripping, and thin wall sleeve 2 is the hollow cylinder structure, on the telescopic outer wall of thin wall, four margins of evenly distributed 3 and four neutral gear 4, margin 3 and neutral gear 4 alternate distribution, and margin 3 plays the cutting action, and neutral gear 5 is used for getting rid of the smear metal.
Before use, the tool shank 1 is first coupled to an electric tool or machine tool.
During the use, electric tool or lathe drive handle of a knife 1 rotatory: then, the rotating thin-wall sleeve 2 is contacted with the sharp corner part of the mechanical part 5; during the contact with the mechanical part 5, since the four margins 3 are thin-walled, they are compressed and deformed, i.e. they are free from sharp corners and form smooth-transition arcs.
