Description
Technical field
The present invention relates to the machine tool chief axis of a kind of self-lubricating, belong to machine tool technology field.
Background technology
Machine tool chief axis refers to the axle driving workpiece or cutter to rotate on lathe.Generally formed master by main shaft, bearing and driving member (gear or belt wheel) etc. and be mainly used to support driving parts such as gear, belt wheel, transmitting movement and moment of torsion in the machine, such as machine tool chief axis；Have for clamping workpiece, such as axle.[1] except the lathe that the main motion such as planer, broaching machine is rectilinear motion, most of lathes have spindle unit.The kinematic accuracy of spindle unit and the rigidity of structure are the key factors determining crudy and stock-removing efficiency.The index weighing spindle unit performance is mainly running accuracy, rigidity and velocity adaptive.1. running accuracy: when main shaft rotates, the radial and axial of appearance is beated on the direction affect machining accuracy, depends mainly on manufacture and the assembling quality of main shaft and bearing.2. dynamic and static rigidity: depend mainly on the bending stiffness of main shaft, the rigidity of bearing and damping.3. velocity adaptive: the maximum speed of permission and the range of speeds, depends mainly on structure and the lubrication of bearing and radiating condition.
General lathe main axis device, including gear housing, machine tool chief axis, bearing and labyrinth collar, machine tool chief axis is arranged in gear housing, and machine tool chief axis is provided with multiple bearing, and the end of described gear housing is provided with labyrinth collar.The mode of traditional machine tool mainshaft bearing lubrication is filling advanced lubrication fat on bearing, through long-term use, labyrinth collar weares and teares, and gap increases, when machine cut, coolant can enter bearing along main shaft, and advanced lubrication fat generation saponification is gone bad so that the high temperature resistant and adhesive ability of advanced lubrication fat declines, the lubrication making bearing can not get ensureing, cause process Product Precision does not reach requirement, and had a strong impact on the service life of bearing, added unnecessary maintenance load.
For lathe, having several index, one is the speed of mainshaft, and two is geometric accuracy, and three is the rigidity of machine tool.Wherein the speed of mainshaft is an important indicator, and the factor affecting machine spindle speed is a lot, as: single-piece work precision, workpiece material and rigidity, bearing accuracy and assembling quality, also have lubricating system.Wherein principal axis lubrication mode is very big on speed of mainshaft impact.
Existing machine tool spindle lubricating mode has following several: grease lubrication, thin oil lubricant, fog lubrication.In these three lubricating system, the first grease lubrication is simplest lubricating system, be suitable for slow-speed of revolution main shaft, once add oils and fats can with several years, with low cost；Shortcoming is: lubricants capacity cannot adjust, and changes difficulty after lubricating oil is contaminated, and heating is big, and heat-sinking capability is poor, is unfavorable for high rotating speed.The second thin oil lubricant is lubricating system more common at present, is characterized as being lubricating oil and can be recycled；Shortcoming is: lubricants capacity be difficult to control, oil mass give many time, oil is taken up by bearing, produce stir heating of oil, thus reducing the speed of mainshaft, it is suppressed that spindle speed, oil mass give hour, lubricate insufficient, bearing heating cannot be taken out of.The third is fog lubrication, and this kind of lubricating system is that gas after lubricating oil atomization, will be delivered to bearing place, main shaft bearing is lubricated, feature: the speed of mainshaft is high, generates heat little, is a kind of mode preferably；Shortcoming is: owing to oil is to be provided by oil sprayer, oil mass is less, is not suitable for heavy duty machine tools, and oil can not all reclaim, and can not utilize by secondary, and mist of oil is big for environment pollution.
The open such a machine tool chief axis of Chinese utility model patent description CN201644814U, belongs to machine tool technology field.Including main shaft and the bearing being arranged on main shaft two ends, it is characterised in that main shaft two ends are provided with bearing holder (housing, cover), and bearing holder (housing, cover) is arranged on the inner side of main shaft bearings at both ends, the inner peripheral surface of bearing holder (housing, cover) is provided with oil pocket, and bearing holder (housing, cover) periphery is socketed with collar bush.Bearing is bidirectional angular contact thrust ball bearing.This utility model is rational in infrastructure simply, manufactures easily, and main shaft precision is high, is conducive to improving the machining accuracy of lathe, is particularly suitable for the bigger occasion of axially loaded and meets Digit Control Machine Tool machining high-precision requirement.But the surface lubrication of this machine tool chief axis is not as, in running, two ends are easily subject to impact and damage, and the bad monitoring of main shaft temperature, can cause that the situation that main shaft temperature is too high and burns out occurs.
The open such a machine tool chief axis of Chinese utility model patent description CN202684113U, it axis body including there is centre bore, with the bare terminal end that machine tool or work piece are connected and drive end that is relative with bare terminal end and that be connected with driving mechanism, the end face of drive end is evenly arranged with 4 louvres for placing radiating tube, the central axis of 4 louvres all with the centerline axis parallel of centre bore.But the surface lubrication of this machine tool chief axis is not as, in running, two ends are easily subject to impact and damage, and the bad monitoring of main shaft temperature, can cause that the situation that main shaft temperature is too high and burns out occurs.
Summary of the invention
The technical problem to be solved in the present invention is to provide the machine tool chief axis of a kind of self-lubricating, and the machine tool chief axis of this self-lubricating solves that surface lubrication is bad, main shaft two ends are easily subject to impact and damages and problem that main shaft is easily burnt because temperature is too high.
nullIn order to solve above-mentioned technical problem，The machine tool chief axis of the self-lubricating of the present invention includes main shaft axis body、Axle sleeve，Main shaft axis body is arranged in axle sleeve，The two ends of described axle sleeve are provided with inner flange and outward flange dish，It is tightly connected by telescopic sealing snare between described inner flange and outward flange dish，It is provided with several elastic devices in described sealing snare，The two ends of described each elastic device are fixing with inner flange and outward flange dish respectively to be connected，It is provided through oil inlet pipe between described outward flange dish and main shaft axis body，Described spindle shaft surface is provided with several holes，Inside each hole, place is respectively provided with one piece of sponge，Described hole outside is provided with filter screen，It is protruding that described axle sleeve inner surface is uniformly provided with several，It is provided with temperature sensor between described main shaft axis body and axle sleeve，The external side of spindle shaft is provided with controller、Warning devices，Described temperature sensor、Warning devices is connected with controller respectively.
