Description
Technical field
The present invention relates to the vertical or horizontal boring-milling center of a kind of full machine oil seal lubrication, belong to the boring and milling field of machine tool equipment.
Background technology
Boring and milling (vertical or horizontal) lathe is the machining equipment of commonly using.Boring and milling machine is the lathe that workpiece is carried out Milling Process with milling cutter, outside milling machine decapacitation milling plane, groove, the gear teeth, screw thread and the splined shaft, can also process the profile of more complicated, and its efficient is high than planer, is used widely in machine-building and repairing department.
The boring and milling head outer of cantilevered boring and milling machine is contained in the milling machine on the cantilever, and lathe bed is horizontally disposed, and cantilever can be done along lathe bed one heel post guide rail vertically mobile up and down usually, and cantilever also can be along column guide rail adjustment height, and milling head moves along cantilevered rail.
Boring and milling (vertical or horizontal) lathe headstock can be along the vertical mobile boring machine of front column guide rail.Use horizontal boring machine to add man-hour, cutter is contained on main shaft, boring bar or the facing head, can obtain various rotating speeds and the amount of feeding of needs by main spindle box, can move up and down along with the guide rail of main spindle box along front column simultaneously.Main spindle box moves how to carry out transmission by the driven by servomotor ball screw, is the main shaft drives core driven device, adopts the hydrostatic bearing supporting more, is driven by the driven by servomotor ball screw.
Workpiece is installed on the workbench, and workbench can move as portraitlandscape with lower slider and upper saddle, also can return back to around the round guide of upper saddle needed angle, to adapt to various processing situations.
Milling machine screw mandrel axis system mainly contains two kinds of structural shapes, and a kind of is traditional boring bar telescopic structure, has the characteristics of boring deep hole and high-power cutting; Another kind is Modern High-Speed electricity main axle structure, has a rotating speed high, and the speed of service is fast, and the characteristics of its high-speed cutting and fast feed have improved precision and the efficient of lathe greatly.
The application of high-speed electric main shaft on horizontal boring and milling machine is more and more, except spindle speed and precision significantly improve, also simplified the main spindle box internal structure, shortened the manufacturing cycle, especially can carry out high-speed cutting, the electric speed of mainshaft is the highest can be greatly more than the 10000r/min.The horizontal boring and milling machine speed of service is more and more higher, and fast moving speed reaches 25～30m/min, boring bar maximum speed 6000r/min.And the speed of horizontal boring and milling machine machining center is higher, and fast moving is up to 50m/min, acceleration 5m/s2, positional precision 0.008～0.01mm, repetitive positioning accuracy 0.004～0.005mm.
Because the boring and milling machine machining center drive lead screw rotating speed that uses now is more and more higher, drive lead screw main shaft quick heating, in order to cool and lubricated drive lead screw, guarantee machining accuracy, a lot of producers' employing spraying machine oil (mist oil) mode is cooled off and is replaced original machine oil (oil dripping) mode of dripping to cool off, more effectively control the drive lead screw main shaft and heat up, its precision is effectively guaranteed.
No matter but be the spray painting machine oil type of cooling or a machine oil type of cooling, machine oil all can not reuse, because can with little dust, affect machine finish in the cooled machine oil.
