Abstract
The utility model discloses a kind of bearing knives, including cutter hub and blade（4）, the cutter hub is by tool apron（1）And cutter head（2）It constitutes；The tool apron（1）One end is cube, and the other end is that section is trapezoidal connecting seat（3）；The connecting seat（3）One end connects cutter head（2）；The cutter head（2）For cylinder, cutter head（2）Inclined and connecting seat（3）Connection；The blade（4）It is arranged in cutter head（2）On.The utility model limits the usable floor area of blade by limiting slot, can be after portion blade excessive wear, and replacing using face can come into operation again, improve blade utilization rate, also reduce production cost.
Description
Technical field
The utility model is related to bearing knife field more particularly to a kind of bearing knives.
Background technology
Requirement with numerical control machining center and numerically-controlled machine tool to Product Precision is continuously improved, and the application of bearing knife is increasingly
Extensively, need the product category of working process also more and more.
After the blade of present bearing knife uses once mostly, just re-replaced newly by discarded needs due to abrasion etc.
Blade, service life is short, and cannot be processed to the product of ting model.
Utility model content
The purpose of the utility model is to provide a kind of bore hole bearing knives.The utility model limits knife by limiting slot
The usable floor area of piece improves blade utilization rate, also reduces production cost
A kind of bearing knife of technical solutions of the utility model, including cutter hub and blade, the cutter hub are made of tool apron and cutter head；
Described tool apron one end is cube, and the other end is that section is trapezoidal connecting seat；Described connecting seat one end connects cutter head；The knife
Head is cylinder, and cutter head is inclined to be connect with connecting seat；The blade is arranged on cutter head.
Aforementioned cutter head angle of inclination is 7 °.
Aforementioned connecting seat both sides are smooth to be recessed inwardly；The connecting seat upper table is tilted towards side, concordant with blade.
The angle of inclination of aforementioned connecting seat upper surface is 7 °.
The aforementioned high 20mm of tool apron.
The junction of aforementioned connecting seat and cutter head is equipped with to the inclined limiting slot in side, and the blade is arranged in limiting slot
It is interior.
Previous insert is truncated cone-shaped, the high 4.88mm of blade.
Aforementioned limiting slot matches with blade.
Compared with prior art, the utility model limits the usable floor area of blade by limiting slot, can be in part knife
After pad wear is excessive, replacing using face can come into operation again, improve blade utilization rate, also reduce production cost.
The utility model uses inclined cutter head so that blade can process the bearing of more Multiple Shape, and further limit
That has made blade uses position, increases machining accuracy, reduces processing loss, reduce production cost.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model.
Label in attached drawing be：1- tool aprons, 2- cutter heads, 3- connecting seats, 4- blades, 5- limiting slots.
Specific implementation mode
The utility model is described further with reference to the accompanying drawings and examples, but is not intended as limiting the utility model
The foundation of system.
Embodiment 1.
A kind of bearing knife, including cutter hub and blade 4, as shown in Figure 1, the cutter hub is made of tool apron 1 and cutter head 2；It is described
1 one end of tool apron is cube, and the other end is that section is trapezoidal connecting seat 3；3 one end of the connecting seat connects cutter head 2；The knife
First 2 be cylinder, and cutter head 2 is inclined to be connect with connecting seat 3；The blade 4 is arranged on cutter head 2.
2 angle of inclination of the cutter head is 7 °.
3 both sides of the connecting seat are smooth to be recessed inwardly；3 upper table of the connecting seat is tilted towards side, flat with blade 4
Together.
The angle of inclination of 3 upper surface of the connecting seat is 7 °.
1 high 20mm of the tool apron.
The junction of the connecting seat 3 and cutter head 2 is equipped with to the inclined limiting slot 5 in side, and the setting of the blade 4 is limiting
In slot 5.
The blade 4 is truncated cone-shaped, 4 high 4.88mm of blade.
The limiting slot 5 matches with blade 4.
Before use, blade 4 is placed in limiting slot 5, make to be screwed.
When finding that 4 part wears degree currently in use of blade is larger, can not carry out again in use, screw can be unscrewed
But do not remove, blade 6 rotated, make the degree of wear low or it is intact be partially disposed in 5 opening of limiting slot, tighten screw,
Then blade 6 can continue to be used.
When the whole damaged or degree of wear of blade 4 is very big, when can not reuse, unscrews and remove screw, take out blade
4, after placing new blade 4, tightens screw and then used again.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
