The utility model is to adopt following proposal to realize: a kind of numerical-control machine tool for processing spiral bevel gear comprises lathe bed, workpiece box, workpiece box panoramic table, toolbox, toolbox support post; Described lathe bed is the T font, and the lathe bed plane is provided with two groups of orthogonal track X, Z, and described workpiece box panoramic table is installed in that described track X goes up and can endwisely slipping along track X; Described toolbox support post is installed in described track Z and upward and by screw mandrel draws its endwisely slipping along track Z; Described workpiece box is installed on the described workpiece box panoramic table by turntable bearing, and the axle center of described turntable bearing overlaps with described workpiece box center of gravity; Described toolbox support post is a gantry structure, and a side at described gantry is provided with the toolbox sliding rail Y perpendicular to described track Z, is provided with two traction screw mandrels that are parallel to described track Y in gantry; On the center of gravity cross section of described toolbox, be provided with the silk hole that is in cutter spindle both sides in the described toolbox and axis and cutter spindle axis normal, described toolbox is by on the traction screw mandrel of described silk hole spinning in described gantry, the side of described toolbox one end is provided with slideway, the axis normal of cutter spindle in the axis of described slideway and the described toolbox, described slipway clamp is contained on the toolbox sliding rail Y that is located on the described toolbox support post, in described workpiece box bottom the workpiece box device for revolving and driving is installed.
In the utility model, described workpiece box device for revolving and driving is the crack transmission worm gear or the crack driving gear pair that disappears of disappearing.
In the utility model, the described crack transmission worm gear that disappears is meshed by two worm and wheels and constitutes; The described crack driving gear pair that disappears is meshing with each other by three gears and constitutes.
Operation principle of the present utility model is sketched in following: when a kind of numerical-control machine tool for processing spiral bevel gear of the utility model is worked, lathe is under the numerical control program control of setting, each parts self contained function, wherein: the planer-type support post is made Z to moving along the track Z on the lathe bed; Toolbox is made Y to motion at support post upper edge track Y; Panoramic table is made X to motion at lathe bed upper edge track X; Workpiece box is done gyration on panoramic table; The workpiece box main shaft self is done gyration; The motion follow procedure control of above-mentioned five directions takes exercises simultaneously or partly; Then by default rotating speed independent operation, the stack of above-mentioned six kinds of motions (just usually said six-axle five-linkage) can realize the cutting to workpiece, finally processes qualified spiral bevel gear by design parameter in the gyration of cutter spindle.
The utility model is owing to adopt said structure, utilize the turntable bearing axle center to overlap with the workpiece box center of gravity, and by the crack transmission that disappears of two gear clearance elimination transmissions or twin worm, make compact integral structure, the workpiece box radius of gyration reduces greatly, and centrifugal force is little during revolution, makes the workpiece box motion more steady, effectively reduced the size of workpiece box support member, reduced requirement support member rigidity; Simultaneously, because the radius of gyration of workpiece box is little, its angle of revolution obviously increases, and the utility model angle of revolution can reach-90 degree-90 degree; The phenomenon of overcome effectively that workpiece box biasing radius of gyration stationarity big, gyration in the prior art is poor, workpiece box and toolbox being interfered mutually in the revolution.Simultaneously, the utility model adopts the planer-type support post, and toolbox by the double lead traction, moves up and down in gantry of support post stably, makes distortion of support post left-right symmetry holding capacity and thermal deformation, thereby effectively reduces the distortion of support post; In addition, the toolbox center of gravity is between the two traction screw mandrels, when moving acceleration and deceleration up and down, can not produce disturbing moment, thereby, effectively improve the positioning accuracy of toolbox.In sum, the utility model is rational in infrastructure, easy for operation, the workpiece box radius of gyration is little, the angle of revolution is big, the lathe volume is little, operate steadily, cutter positioning precision height, be suitable for suitability for industrialized production, be specially adapted to the digital control processing of big specification spiral bevel gear.
