Abstract
The utility model discloses a gun drill, including gun drill main part, gun drill head and drill bit, the gun drill head includes head body, top cover, piston and the flexible hydro -cylinder of control piston, the top cover links to each other with the piston, the head body is inside have the cutting fluid passageway, with the communicating oil circuit passageway of hydro -cylinder, and chip removal export, the cutting fluid passageway even has at least one nozzle, and the cutting fluid is finally sprayed to the drill bit by the nozzle through the cutting fluid passageway, washes out the sweeps in the flute of drill and discharge through the chip removal export. The utility model discloses an oil circuit passageway, cutting fluid passageway just only need a hydro -cylinder to drive the top cover and withstand the processing work piece inside all locating the head body, more traditional gun drill simple structure, and the outward appearance is succinctly pleasing to the eye, and the maintenance cost is low.
Description
Technical field
The present invention relates to a kind of rig is and in particular to a kind of drill gun.
Background technology
In field of machining, drill gun is used for deep hole processing.Drill gun commonly used hole, form of axle cooperation in clamping,
Will drill gun drillstock（Cutter）Load in the guide pin bushing of cylindrical tube, then with hold-down bolt, the drillstock of drill gun is fixed on circle
In the guide pin bushing of cylinder.Coolant system and chip removal system work drill gun simultaneously in process.
The cutting fluid that existing drill gun has, oil circuit pipeline are to expose design, and drill gun head needs multiple cylinders, and structure is multiple
Miscellaneous, installation, maintenance process is excessively loaded down with trivial details, maintenance cost is high it is impossible to meet actual demand.
Content of the invention
The technical problem to be solved in the present invention is the defect overcoming prior art, provides a kind of drill gun, and this drill gun is more traditional
Drill gun structure is simpler, and tailored appearance is attractive in appearance, and maintenance cost is low.
For solving above-mentioned technical problem, the technical solution used in the present invention is：
A kind of drill gun, including drill gun main body, drill gun head and drill bit, described drill gun head includes head body, top cover, work
Fill in and control the oil cylinder that piston stretches；Described top cover is connected with piston；There is inside described head body cutting fluid channel and institute
State asphalt channel and the chip removal outlet that oil cylinder communicates, described cutting fluid channel is connected with least one nozzle, the resected liquid of cutting fluid
Passage is finally sprayed from nozzle to drill bit, the scrap in flute of drill is washed out and exports through chip removal and discharge.
Preferably, described drill gun main body has line rail, screw mandrel, main shaft, spindle motor and Timing Belt, described drill bit and main shaft
Coaxially, spindle motor drives main shaft rotation by Timing Belt, and screw mandrel drives drill bit axial feed simultaneously.
Preferably, described nozzle is high pressure nozzle, and described cutting fluid channel is connected with two nozzles.
Preferably, the chip area of drill bit is the V-groove axially opening up along drill bit, and described chip area passes through the center of drill bit
Axis, drill bit also has two coolant ducts.
Preferably, described piston is connected by dust ring, wear ring, O-ring with the end of described head body.
Preferably, near described drill gun head, also there is work light.
The beneficial effect that the present invention is reached：
The asphalt channel of the present invention, cutting fluid channel are all inside head body, and only need an oil cylinder to drive top cover
Withstand processing workpiece, more traditional drill gun structure is simple, and tailored appearance is attractive in appearance, and maintenance cost is low；
Spindle motor drives main shaft rotation by Timing Belt, and screw mandrel drives drill bit axial feed simultaneously, it is to avoid drill bit exists
Because larger axial force is trembleed it is ensured that crudy in boring procedure.
Brief description
Fig. 1 is the sectional view of drill gun in the preferred embodiment of the present invention；
Fig. 2 is the structural representation of drill gun head in Fig. 1；Wherein：
1. drill gun head, 11. head body, 12. pistons, 13. nozzles, 14. chip removal outlets, 2. drill gun main body,
3. drill bit, 4. work light, 5. main shaft, 6. spindle motor, 7. screw mandrel, 8. line rail, 9. top cover.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
As shown in Figure 1-2, a kind of drill gun, including drill gun main body 2, drill gun head 1 and drill bit 3, drill gun head 1 includes head
The oil cylinder that body 11, top cover 9, piston 12 and control piston 12 stretch；Described top cover 9 is connected with piston 12；Described head body
There is inside 11 asphalt channel and the chip removal outlet 14 that cutting fluid channel is communicated with described oil cylinder, described cutting fluid channel is connected with
Two nozzles 13, nozzle 13 is high pressure nozzle 13.Cutting fluid resected liquid passage is finally sprayed from nozzle 13 to drill bit 3, will bore
Scrap in 3 chip areas washes out and through chip removal outlet 14 discharge.
Drill gun main body 2 has line rail 8, screw mandrel 7, main shaft 5, spindle motor 6 and Timing Belt, and described drill bit 3 is same with main shaft 5
Axle, spindle motor 6 drives main shaft 5 to rotate by Timing Belt, and screw mandrel 7 drives drill bit 3 axial feed simultaneously.
The chip area of drill bit 3 is the V-groove axially opening up along drill bit 3, and described chip area passes through the central shaft of drill bit 3
Line, drill bit 3 also has two coolant ducts.
Piston 12 is connected by dust ring, wear ring, O-ring with the end of described head body 11.3, drill bit is nearby also
There is work light 4.
In the present invention, spindle motor 6 drives main shaft 5 to rotate by Timing Belt, and then drives drill bit 3 to rotate, and leads to simultaneously
Cross Timing Belt and drive screw mandrel 7, make drill bit 3 do axial feed.In boring, oil cylinder drives top cover 9 to stretch, and top cover 9 withstands workpiece,
Prevent oil leak and scrap splash, the scrap that boring produces is washed out by high pressure nozzle 13.
The above is only the preferred embodiment of the present invention it is noted that ordinary skill people for the art
For member, on the premise of without departing from the technology of the present invention principle, some improvement can also be made and deform, these improve and deform
Also should be regarded as protection scope of the present invention.
