The novel horizontal machining center with compound drill gun function
Technical field
The utility model relates to horizontal Machining centers technical field, exactly relates to a kind of being mainly used in part of automobile engine is carried out to accurately machined horizontal Machining centers.
Background technology
Part of automobile engine oil injector body manufacturing procedure is many, difficulty of processing is large.The cutter inner cooling pressure that common horizontal machining center main shaft configures is generally lower than 7MPa, cannot adopt drill gun to realize draw ratio >=60 and diameter is efficient, the high accuracy processing of the deep hole of Φ 1mm~Φ 30mm, and the lathe that is specifically designed to drill gun processing does not possess the milling that machining center possesses, boring, fraising, tapping, the multiple cutting function such as bore hole, if publication number is CN201399598, within open day, be to disclose a kind of lathe that carries out deep hole gun drill processing and single-pipe drill processing on February 10th, 2010, its technology contents be on front guide case, offer be laterally used to wear before guide case installing hole and longitudinally penetrate before the relief hole of guide case bottom, by installing hole can be in the front-end and back-end of front guide case respectively fixing and the matching used drill gun accessory of deep hole gun drill or with the matching used single-pipe drill accessory of single-pipe drill, the main shaft of main spindle box is provided with the elastic jacket that deep hole gun drill or single-pipe drill can be installed.
So, no matter be existing general-purpose machining center, or all can not realize clamped one time for the lathe of drill gun processing, thereby complete the working procedures contents such as milling to workpiece, boring, tapping, bore hole, drill gun deep hole.Practice of the prior art is by milling, boring, fraising, tapping, bore hole and drill gun deep hole separate machined, will cause like this uniformity of part to be difficult to guarantee, production efficiency is lower.
Summary of the invention
For solving the existing defect of above-mentioned prior art, the utility model proposes a kind of novel horizontal machining center with compound drill gun function, the utility model is integrated with drill gun drilling function, can on same machining center, realize working procedures contents such as the milling of workpiece, boring, tapping, bore hole, drill gun deep holes, thereby guaranteed the processing uniformity of part, improve machining accuracy, also improved production efficiency simultaneously.
The utility model is by adopting following technical proposals to realize:
A kind of novel horizontal machining center with compound drill gun function, comprise lathe bed, column, main spindle box and electric main shaft, it is characterized in that: the one end at described electric main shaft is provided with swivel joint, the other end of electricity main shaft is provided with handle of a knife, on handle of a knife, clamping has drill gun, and the cooling fluid in cutter inner cooling station is delivered to described handle of a knife by described swivel joint.
The rotating speed of described electric main shaft is not less than 15000r/min.
The coolant pressure of carrying in described cutter inner cooling station is not less than 15MPa.
Described handle of a knife adopts and can be connected by plug joint with electric main shaft.
Compared with prior art, the beneficial effect that the utility model reaches shows:
1, in the utility model, by the mode of " one end at electric main shaft arranges swivel joint; the other end of electric main shaft arranges handle of a knife; clamping drill gun on handle of a knife; the cooling fluid in cutter inner cooling station is delivered to described handle of a knife by described swivel joint ", also i.e. integrated drill gun machining functions on traditional horizontal Machining centers, thereby can on same machining center, realize working procedures contents such as the milling of workpiece, boring, tapping, bore hole, drill gun deep holes, thereby guaranteed the processing uniformity of part, improve machining accuracy, also improved production efficiency simultaneously.
2, in the utility model, the rotating speed of electricity main shaft is not less than 15000r/min, the coolant pressure of carrying in cutter inner cooling station is not less than 15MPa, adopt electric main shaft and the cutter inner cooling station of such special parameter, can realize the ability of efficient, high accuracy processing of the deep hole of drill gun Φ 1mm~Φ 30mm, draw ratio >=60, processing aperture Φ 1.5mm, during the hole of dark 95mm, hole tolerance≤H8, linearity≤0.1mm, Hole Wall Roughness≤Ra0.1, process time≤50 second, carry out accurately machined requirement thereby can meet part of automobile engine.
3,, in the utility model, handle of a knife adopts and can be connected by plug joint with electric main shaft, can facilitate replacing and the maintenance of drill gun and electric main shaft.
Accompanying drawing explanation
Below in conjunction with specification drawings and specific embodiments, the utility model is described in further detail, wherein:
Fig. 1 is structural representation of the present utility model
Mark in figure:
1, lathe bed, 2, the NC rotary table that can incline, 3, automatic hydraulic fixture, 4, workpiece (oil injector body), 5, drill gun, 6, handle of a knife, 7, electric main shaft, 8, main spindle box, 9, column, 10, swivel joint, 11, cutter inner cooling station.
The specific embodiment
Referring to Figure of description, preferred forms of the present utility model is: electric main shaft 7 tail ends on machining center have configured fast swivel joint 10.The rotating speed of electricity main shaft is not less than 15000r/min.The cooling fluid that cutter inner cooling station 11 can provide pressure to be not less than 15MPa, is transported to the handle of a knife 6 of spindle nose by swivel joint 10.Handle of a knife 6 can plug joint with electric main shaft 7 employings and be connected.On handle of a knife 6 clamping drill gun 5.Select suitable cutting parameter and cutter inner cooling pressure, can carry out efficiently workpiece 4, the dark aperture of high accuracy drill gun.
