Abstract
The utility model discloses a kind of self cooling fluted drill, including drill bit and supporting rod, interior cooling hole is coaxially provided on the supporting rod, the housing of thin wall type is arranged with outside supporting rod, annular housing is formed between the housing and supporting rod, clamping is laid with multiple radial pores burr week, and the radial pore is connected to the interior cooling hole and the annular housing；The housing is connected with supporting rod upper end by sealing plate, is also plugged with annular oriffice between housing and supporting rod, and ring week, permutation had at least six axial passage on the annular oriffice.The utility model can greatly improve the cooling effect of fluted drill, improve the service life of fluted drill, and annular oriffice both as cooling intermediate, can also enhance stability of bit, and reduce axial runout and vibration.
Description
Technical field
The utility model is related to fluted drill technical fields, and in particular to a kind of self cooling fluted drill.
Background technology
Fluted drill in use, will produce a large amount of heat, generally take away heat by cutting coolant, but
The coolant liquid by being ejected into finished surface, usually will appear spray it is not uniform enough, cause fluted drill hot-spot, quickly grind
Damage fluted drill.
Utility model content
In view of the deficienciess of the prior art, the utility model provides a kind of self cooling fluted drill, fiber crops can be greatly improved
The cooling effect that flower bores, improves the service life of fluted drill.
The utility model provides a kind of self cooling fluted drill, including drill bit and supporting rod, is coaxially provided on the supporting rod interior
Cooling hole, supporting rod are arranged with the housing of thin wall type outside, and annular housing, clamping burr week are formed between the housing and supporting rod
Multiple radial pores are laid with, the radial pore is connected to the interior cooling hole and the annular housing；The housing and folder
It holds bar upper end by sealing plate to be connected, annular oriffice is also plugged between housing and supporting rod, ring week is whole on the annular oriffice
Show at least six axial passage.
Preferably, the cutting slot distance of the housing and the drill bit is at least 30mm.
Preferably, distance is at least 1.2mm between the inner wall of the housing and the outer wall of the supporting rod.
The utility model has following advantageous effects：The cooling effect that fluted drill can be greatly improved, improves fluted drill
Service life, and annular oriffice can also enhance stability of bit both as cooling intermediate, reduce axial runout and shake
It is dynamic.
Description of the drawings
Fig. 1 the utility model partial schematic sectional views.
Fig. 2 the utility model radial direction schematic cross-sectional views.
Specific implementation mode
The utility model is further described in conjunction with drawings and examples：
As depicted in figs. 1 and 2, the utility model provides a kind of self cooling fluted drill, including drill bit 11 and supporting rod 12, clamping
It is coaxially provided with interior cooling hole 13 on bar 12, the housing 14 of thin wall type is arranged with outside supporting rod 12, between housing 14 and supporting rod 11
Annular housing is formed, is laid with multiple radial pores 15 in 12 ring week of supporting rod, radial pore 15 is connected to interior cooling hole 13 and ring
Shape cavity.Housing 14 is connected with 12 upper end of supporting rod by sealing plate 16, and annular is also plugged between housing 14 and supporting rod 12
Orifice plate 17.Ring week, permutation had at least six axial passage 18 on annular oriffice 17, for being used as cooling medium stream road, cooling medium
Can be the either cooling liquid of high speed cold air.
The most short distance of the cutting slot 19 of housing 14 and drill bit 11 is at least 30mm, guarantee do not influence drill bit chip breaking and
Go out bits.
Distance is at least 1.2mm between the inner wall and the outer wall of supporting rod 12 of housing 14, ensures to be fully cooled, and improves cooling
Efficiency, but can not be arranged excessive, when more than 3mm, air drag will increase, and will produce additional vibratory and bounce.
Above are merely preferred embodiments of the utility model, the scope of protection of the utility model is not limited merely to implement
Example, technical solution belonging to the idea of the present invention belong to the scope of protection of the utility model.It should be pointed out that for this
For the those of ordinary skill of technical field, several improvements and modifications without departing from the principle of the utility model, these
Improvements and modifications also should be regarded as the scope of protection of the utility model.
