Description
Technical field
The technical field of boring cutter is the utility model is related to, more specifically a kind of integrated coarse and fine boring cutting tool.
Background technology
Boring cutter is one of most common aperture knife tool in machining, is mainly used in the form processing such as reaming and shaping.
Boring processing is generally divided into heavy boring, half right boring and right boring, and continuously, efficiently coarse-fine process is that metal processing sectors are seek assiduously
Machining based conception.For there is large batch of, high-precision requirement Boring, typically processed using coarse-fine boring combining form,
, thus can not be real, it is necessary to which right boring processing could be carried out by changing fine boring tool after the completion of heavy boring but coarse-fine boring cutter is separated
Now continuous, efficient processing.
To solve existing above mentioned problem, in recent years in the prior art, rough boring cutter and fine boring cutter combination are existed
On one cutter, processing efficiency is improved.One is disclosed in Chinese invention patent Granted publication specification CN102049537B
Kind Disposable coarse-fine integrated boring cutting tool, after the boring cutting tool clamping is on the knife rest of lathe, according to different
Chip depth selects rational chip parameter, starts equipment, rotates workpiece, and first carrying out heavy boring to workpiece using rough boring cutter adds
Work, after heavy boring, micro movement is carried out to the knife rest of clamping cutter, by the point of a knife of fine boring cutter close to machined surface, adjusted
Boring surplus, right boring processing is carried out to workpiece, until workpiece meets the technical requirements of engineering drawing, so as to realize clamped one time, one
The secondary heavy boring for completing hole and right boring processing.Above-mentioned boring cutting tool is applicable the Boring of lathe:Workpiece rotates, and cutter is solid
It is fixed.But the Boring of boring machine is not suitable for it:Workpiece is fixed, cutter rotation.And the cutting edge generally use right angle of existing boring cutter
Chamfering structure, secondary cutting structure is not provided with, after the completion of cutting, when workpiece has elastic deformation, easily causes work pieces process
The finish in face is poor.
The content of the invention
The purpose of this utility model is to provide a kind of coarse-fine integral boring cutting tool, can in the Boring of boring machine,
Continuous coarse-fine processing is realized, improves processing efficiency, and the finish in hole can be improved.
To achieve the above object, the utility model adopts the following technical scheme that:
A kind of integrated coarse and fine boring cutting tool, including handle of a knife and cutter head.The rough boring cutter and fine boring cutter are located at cutter head
Right-hand member, the fine boring cutter and rough boring cutter are located at the both sides of cutter head, the rough boring cutter right side and the handle of a knife left side respectively
Axial spacing is more than the axial spacing of the fine boring cutter right side and the handle of a knife left side, the processing diameter D1 of the rough boring cutter
Less than the processing diameter D2 of the fine boring cutter, Circular Nose Cutting Edge band is designed with knife face after the master of the rough boring cutter and fine boring cutter.
By chamfered transition between plane where plane where the rough boring cutter right side and the fine boring cutter right side, just
In the discharge of cutting swarf.
The fine boring cutter is polycrystalline diamond, improves sharpness and the cutter life of blade, and can further be carried
The surface quality in high hole.
The fine boring cutter is welded on the right-hand member of the cutter head.
The rough boring cutter is hard alloy or polycrystalline diamond.
Rough boring cutter and fine boring cutter are incorporated on a borer by the utility model, rough boring cutter right side and handle of a knife left end
The axial spacing in face is more than the axial spacing of fine boring cutter right side and handle of a knife left side, is realized in boring machine bore hole continuous thick
Finishing, improves hole machined efficiency;Circular Nose Cutting Edge band is designed with knife face after the master of rough boring cutter and fine boring cutter, when cutting edge is cut
After cutting, when workpiece has elastic deformation, Circular Nose Cutting Edge band can realize extruding cutting, improve the surface quality in hole.

Fig. 1 is the structural representation of the utility model gang tool;
Fig. 2 is the front view of the utility model gang tool;
Fig. 3 is the right view of the utility model gang tool;
Fig. 4 is the left view of the utility model gang tool.
Embodiment
In conjunction with accompanying drawing, the utility model embodiment is described in detail:
As shown in Figures 1 to 4, a kind of integrated coarse and fine boring cutting tool, including handle of a knife 1 and cutter head 2.The He of rough boring cutter 3
Fine boring cutter 4 is located at the both sides of the right-hand member of cutter head 2 respectively, and fine boring cutter 4 is welded to connect with cutter head 2.The right side 31 of rough boring cutter 3 and handle of a knife 1
The axial spacing L of left side 111More than the axial spacing L of the right side 41 of fine boring cutter 4 and the left side 11 of handle of a knife 12;The right-hand member of rough boring cutter 3
By the transition of inclined-plane 5 between the place plane of face 31 and the place plane of 4 right side of fine boring cutter 41, it is easy to the discharge of cutting swarf.Heavy boring
After the master of the processing diameter D2 for processing diameter D1 and being less than fine boring cutter 4 of knife 3, rough boring cutter 3 and fine boring cutter 4 circular arc is equipped with knife face
Land 6, the axial direction and the axial direction of handle of a knife 1 corresponding to Circular Nose Cutting Edge band 6 are in the same direction.
Rough boring cutter 3 selects hard alloy, can reduce cutter production cost;Fine boring cutter 4 is polycrystalline diamond, improves blade
Sharpness and cutting-tool's used life, and the surface quality in hole can be improved.
During specific works, by gang tool clamping of the present utility model on boring machine, selected according to different process requirements
Rational chip parameter;Workpiece to be processed is remained stationary as, starts equipment, gang tool rotation;Rough boring cutter 3, which first contacts, to be added
The workpiece of work, heavy boring processing is carried out to workpiece, after the cutting edge of rough boring cutter 3 cuts off heavy boring allowance, when there is elastic shape
During change, the Circular Nose Cutting Edge band 6 of rough boring cutter 3 carries out extruding cutting;With the feeding of cutter, fine boring cutter 4 starts to contact workpiece, to heavy boring
Workpiece after processing carries out right boring processing, after the cutting edge of fine boring cutter 4 cuts off right boring allowance, when there is elastic deformation
When, the Circular Nose Cutting Edge band 6 of fine boring cutter 4 carries out extruding cutting;When processing is completed, a diameter of D2 in hole.Combination of the present utility model
Cutter realizes clamped one time, has been continuously finished heavy boring and the right boring processing in hole, has improved production efficiency;Due to the He of rough boring cutter 3
The blade of fine boring cutter 4 is designed with Circular Nose Cutting Edge band 6, it is possible to achieve the extruding cutting to hole wall, makes the hole wall finally machined
Finish it is more superior than what traditional boring cutter was processed.
