Abstract
The utility model discloses a dry type outside chip removal deep hole drill, which structurally comprises a drill bit, a drill rod and a drill holder. Each of the drill bit and the drill rod is in a hollow structure, central holes in the drill bit and the drill rod are communicated with each other, an air filling port communicated with the central hole in the drill rod is arranged on the drill holder, and an air outlet is arranged on the drill bit. The dry type outside chip removal deep hole drill can be used with a common lathe for machining of especially deep holes, machining cost of the especially deep holes is reduced greatly, chips can be blown out of a chip area by means of compressed air, so that most heat can be directly dissipated, temperature of the chip area can be reduced greatly, and the dry type outside chip removal deep hole drill is especially suitable for machining of graphite deep holes.
Description
Technical field
The utility model relates to a kind of drilling tool, the outer chip removal depth drill of especially a kind of dry type.
Background technology
Deep hole machining to as if the hole of draw ratio (being hole depth L and the ratio of aperture d) greater than 5.The draw ratio of common deep hole adds and can will utilize engine lathe directly to process behind the fluted drill lengthening man-hour between 5～20.But for the special deep hole of draw ratio between 20～100, then need special-purpose deep hole working machine and special deep hole tools to process, not only the more common deep hole of processing cost significantly improves, simultaneously owing to deep hole when deep hole machining is in semi-closed state, the chip removal difficulty, heat conduction and heat radiation is poor, is prone to that the cutter rigidity changes, shake distortion, vexed bits and situation such as fracture.
The utility model content
The technical problems to be solved in the utility model provides the outer chip removal depth drill of a kind of dry type, can be used with engine lathe and carry out special deep hole machining, significantly reduce the cost of special deep hole machining, can utilize compressed air that smear metal is blown out rapidly from the smear metal district during use, thereby most of heat is directly taken out of, significantly reduced smear metal district temperature; Especially be fit to the processing of graphite deep hole.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
The outer chip removal depth drill of a kind of dry type, comprise the drill bit, drilling rod and the taper shank that join successively in the structure, described drill bit, drilling rod are hollow-core construction, and the core hole of this drill bit, drilling rod inside connects mutually, taper shank is provided with the inflation inlet that is communicated with drilling rod inner core hole, and drill bit is provided with the gas outlet.
As a kind of optimal technical scheme of the present utility model, the cross-sectional diameter of described drilling rod is less than the cross-sectional diameter of described drill bit.
As a kind of optimal technical scheme of the present utility model, be screwed connection between described drill bit and the drill rod end.
As a kind of optimal technical scheme of the present utility model, described drill bit is a fluted drill.
As a kind of optimal technical scheme of the present utility model, described gas outlet is arranged at drill end land place.
As a kind of optimal technical scheme of the present utility model, the number of described inflation inlet is two.
As a kind of optimal technical scheme of the present utility model, the number of described gas outlet is two.
Adopt the beneficial effect that technique scheme produced to be: the utility model especially is fit to the processing of graphite deep hole, can significantly reduce the processing cost of special deep hole, cooperate with engine lathe during use, utilize compressed air that smear metal is blown out rapidly from the smear metal district, thereby most of heat is directly taken out of, significantly reduced smear metal district temperature; The utility model more helps compressed air smear metal is blown out because the cross-sectional diameter of drilling rod less than the cross-sectional diameter of drill bit, can form certain clearance between drilling rod and boring inwall; Be screwed connection between drill bit of the present utility model and the drill rod end, be convenient to dismantle and change the drill bit of different size.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of a specific embodiment of the utility model.
Fig. 2 is the schematic diagram of the utility model gas outlet.
Among the figure: 1, drill bit; 11, gas outlet; 2, drilling rod; 3, taper shank; 31, inflation inlet.
The specific embodiment
Referring to accompanying drawing, comprise the spiral bit 1 that joins successively in the structure of a specific embodiment of the utility model, drilling rod 2 and taper shank 3, be screwed connection between drill bit 1 and drilling rod 2 ends, so that the drill bit 1 of dismounting and replacing different size, the cross-sectional diameter of drilling rod 2 is less than the cross-sectional diameter of drill bit 1, can between drilling rod 2 and boring inwall, form certain slit like this, be beneficial to consider to be worth doing the eliminating of body, drill bit 1, drilling rod 2 is a hollow-core construction, and this drill bit 1, the core hole of drilling rod 2 inside connects mutually, taper shank 3 is provided with two inflation inlets 31 that are communicated with drilling rod 2 inner core holes, and land place, drill bit 1 top is provided with two gas outlets 11.
Operation principle of the present utility model is: the utility model cooperates with engine lathe in use, utilizes compressed air that smear metal is blown out rapidly from the smear metal district, thereby most of heat is directly taken out of, significantly reduces smear metal district temperature; The utility model more helps compressed air smear metal is blown out because the cross-sectional diameter of drilling rod 2 less than the cross-sectional diameter of drill bit 1, can form certain clearance between drilling rod 2 and boring inwall; Be screwed connection between drill bit 1 of the present utility model and drilling rod 2 ends, be convenient to dismantle and change the drill bit of different size.The utility model especially is fit to the processing of graphite deep hole, can significantly reduce the processing cost of special deep hole.
Foregoing description only proposes as the enforceable technical scheme of the utility model, not as the single restrictive condition to its technical scheme itself.
