Abstract
The utility model patent discloses a kind of flat chamfer compound cutting tool of cunning, including cutter hub and cutter head, it is characterised in that：Preceding blade and rear blade are provided on the cutter head, wherein, the preceding blade is made of two parts, front and rear, forepart is in 45 ° of angles with cutter hub axis, and rear portion is 15 ° with cutter hub axis angle a, which is grouped together chamfering and sliding put down, manufacturing procedure is simplified, only needs drilling, compound chamfers, tapping.It is round and smooth without water chestnut to machine rear chamfer site, without artificial treatment burr, and size ensures by cutter, and there is no the situation of the inaccurate depth of artificial control, working hour also saves 30%.
Description
Technical field
The utility model patent is related to machine tooling cutter, especially a kind of cunning for the threaded hole for being machined with seal request
Flat chamfer compound cutting tool.
Background technology
At present, in technical field of mechanical processing, many threaded holes have seal request, need to use bolt with sealing ring etc.
Workpiece is mounted in the threaded hole, is needed to threaded hole back seal angle, and when processing such threaded hole, normal procedure is to bore
Hole, sliding flat, back seal angle, the pilot angle of falling screw thread, tapping.Process that not only process is more, and working hour is long, and during tool changing by this process
Between reduce processing efficiency, also reduce the knife-changing system service life, it is necessary to often safeguard or replace knife-changing system, it is deep-controlled with work
People's operation has relationship, is susceptible to and is connected bad, dimension overproof.And the chamfer site processed is jagged, need to manually repair
Reason, such as processing with great difficulty do not destroy sealing ring when installation, cause to leak.
Utility model content
For the problems of the prior art, the purpose of this utility model is to provide for a kind of flat chamfer compound cutting tool of cunning, should
Two kinds of chamferings and a kind of cunning are put down and combined by cutter, simplify process, without manual repair's burr, high precision machining.
In order to achieve the above object, the technical solution of the utility model is：
A kind of flat chamfer compound cutting tool of cunning, including cutter hub and cutter head, it is characterised in that：Preceding knife is provided on the cutter head
Piece and rear blade, wherein, the preceding blade is made of two parts, front and rear, and forepart is in 45 ° of angles with cutter hub axis, after
Portion is 15 ° with cutter hub axis angle a.
Further, the cutter hub and cutter head are integral type, and preceding blade and rear blade are welded on knife by cold welding technique
On head.
Further, the cutter hub and cutter hub material are 40cr, and heat treatment process are needed to handle after its machine-shaping；
The preceding blade and rear blade are carbide chip.
Further, the preceding blade and rear blade are ground by numerical control five-axle knife sharpener.
Further, it is no more than between the preceding blade and rear blade relative to the concentricity of cutter hub and cutter head
0.01mm。
The compound tool is the processing for directly carrying out bore portions after drilling, then carries out tapping.The class to be processed
The particularity of type hole is that its 15 ° of chamferings and platform are to belong to sealing surface, tighter for the spatial relationship requirement of angle and platform,
Similar to the seal for adding one section of special shape in regular screw threads aperture.The design of this compound tool greatly improves such threaded hole
Quality stability and processing convenience.Because such aperture is more special, for before, special aperture is added
It is equally convenient that work is simplified to common aperture processing.In particular, in that on black skin this pores processing embody it is more prominent.
Compared with prior art, the structure novel of the flat chamfer compound cutting tool of cunning provided by the utility model is unique, the cutter
Chamfering and sliding put down are grouped together, manufacturing procedure is simplified, only needs drilling, compound chamfers, tapping.It is fallen after machining
Angular position is round and smooth without water chestnut, and without artificial treatment burr, and size ensures by cutter, and there is no the inaccurate depth of artificial control
Situation, working hour also save 30%.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it can also be obtained according to these attached drawings other attached drawings.
Attached drawing 1 is the structure diagram of the flat chamfer compound cutting tool of this cunning.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of flat chamfer compound cutting tool of cunning, cutter hub 1 and cutter head 2 including integral type, cutter hub 1 are used to install
Onto cutterhead, cutter head 2 is welded with preceding blade 21 and rear blade 22 on the cutter head 2 for installing blade by cold welding technique,
Wherein, the preceding blade 21 is made of two parts, front and rear, and forepart is with cutter hub axis in 45 ° of angles, rear portion and cutter hub axis
Wire clamp angle a is 15 °, and the cutter hub 1 and 2 material of cutter hub are 40cr, and heat treatment process is needed to handle after its machine-shaping；Institute
The preceding blade 21 and rear blade 22 stated are carbide chip, and the preceding blade 21 and rear blade 22 are ground by numerical control five-axle
Knife machine is ground, and is no more than between the preceding blade 21 and rear blade 22 relative to the concentricity of cutter hub 1 and cutter head 2
0.01mm.The cutter after drilling, directly carries out the processing of bore portions, then carries out tapping, completes processing, multiple by this
Cutter is closed, is processed while realizing 15 ° of angles of orifice part and platform slot, improves processing efficiency, ensure that processing quality, processes ruler
Very little requirement, and impulse- free robustness, without artificial treatment again.
It is understood that above with respect to the specific descriptions of the utility model, it is merely to illustrate the utility model and is not
The described technical solution of the utility model embodiment is limited to, it will be understood by those of ordinary skill in the art that, it still can be with
It modifies to the utility model or equivalent replacement, to reach identical technique effect；As long as meet using needs, all in this reality
Within novel protection domain.
