Description

Composite reverse milling cutter

Technical Field

The utility model relates to a milling cutter technical field especially relates to a compound milling cutter that falls.

Background

A milling cutter is a rotating tool with one or more cutter teeth for milling. When in work, each cutter tooth cuts off the allowance of the workpiece in sequence and intermittently. The milling cutter is mainly used for processing planes, steps, grooves, formed surfaces, cut-off workpieces and the like on a milling machine.

The existing chamfer milling cutter only singly chamfers and deburs a workpiece, can not perform cutting processing, and has an application range of only chamfers on the surface appearance of the workpiece and chamfers on the surface of a processed inner hole.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving prior art well chamfer milling cutter, only the singleness carries out the chamfer to the work piece, and the burring can not carry out cutting process, and application scope is only work piece surface appearance chamfer and the problem of having processed hole surface chamfer, and the compound milling cutter that falls who provides.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a compound chamfer, includes the handle of a knife, the lower extreme of handle of a knife is equipped with chamfer portion, the lower lateral wall fixedly connected with milling cutter head of chamfer portion, milling cutter head's cutting edge quantity is five, chamfer portion's cutting edge quantity is six.

Preferably, the angle of the chamfer cutting edge is 116 °.

Preferably, the chamfer cutting edge helix angle is 45 °.

Preferably, the side wall of the knife handle is provided with a mounting hole.

Preferably, an arc groove is formed between the two cutting edges of the milling head.

Preferably, a groove body is arranged between the two cutting edges of the chamfering part.

Compared with the prior art, the utility model provides a compound milling cutter that falls possesses following beneficial effect:

this compound chamfer cutter through handle of a knife, chamfer portion and the milling cutter head that sets up, can mill the back to the work piece, carries out chamfer operation and chamfer smooth precision height to the work piece, can not produce the defective products, has reduced the cost of manufacture.

And the part that does not relate to among the device all is the same with prior art or can adopt prior art to realize, the utility model discloses can mill the back to the work piece, carry out chamfer operation and chamfer smooth precision height to the work piece, can not produce the defective products, reduced the cost of manufacture.

Drawings

Fig. 1 is a schematic structural view of the composite reverse milling cutter provided by the utility model.

In the figure: 1 handle of a knife, 2 chamfer portion, 3 milling cutter head, 4 mounting holes, 5 circular arc grooves, 6 cell bodies.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Referring to fig. 1, the composite inverse milling cutter comprises a cutter handle 1, wherein an inverse angle part 2 is arranged at the lower end of the cutter handle 1, a milling cutter head 3 is fixedly connected to the lower side wall of the inverse angle part 2, the number of cutting edges of the milling cutter head 3 is five, and the number of cutting edges of the inverse angle part 2 is six.

The cutting edge of the chamfer 2 has an angle of 116 deg., which improves the cutting ability of the chamfer 2.

The cutting edge helix angle of the chamfer part 2 is 45 degrees, and the cutting toughness of the chamfer part 2 is improved.

The side wall of the knife handle 1 is provided with the mounting hole 4, so that the knife handle 1 can be conveniently and fixedly mounted.

An arc groove 5 is formed between two cutting edges of the milling head 3, and waste materials are conveniently discharged when the workpiece is milled.

A groove body 6 is formed between the two cutting edges of the chamfering part 2, and waste materials are conveniently discharged during chamfering.

The utility model discloses in, during the use, through handle of a knife, chamfer portion and the milling cutter head that sets up, can mill the back to the work piece, carry out chamfer operation and the smooth precision height of chamfer to the work piece, can not produce the defective products, reduced the cost of manufacture.
