Technical field: the utility model belongs to the machine tool technology field, is specifically related to the vertical numerical control turn-milling machine tool that the polygon axle of a kind of turnning and milling part, basin tooth and umbrella tooth part are used.

Background technology: at present, mostly small-size shaft part, basin tooth and the umbrella tooth part of processing is to adopt traditional turning and milling technology processing, the turning processing characteristic is that the workpiece rotary cutter is static, the Milling Process characteristics are that the cutter rotational workpieces is static, when needs processing two ends or certain position are polygon axle part such as triangle, four jiaos, hexagonal, need multiple clamping and location operation break-down to process, its shortcoming be complicated operation, working (machining) efficiency low, easily form cumulative limit, low precision, cost height; And the employing Cutter Body Processing with Machining Center, it is deposited machining center and is costing an arm and a leg, and has the error of division, efficient is low, processing cost is high defective.

Summary of the invention: the purpose of this utility model provides a kind of simple to operate, and the efficient height can improve machining accuracy, the vertical numerical control turn-milling machine tool that production cost is low.

The technical solution of the utility model is: a kind of vertical numerical control turn-milling machine tool, form by rotating hydraulic anchor clamps and removable pallet arrangement that the clamping workpiece of lathe bed, drive motors, speed-changing gear box, numerical control device and numerical control device control is used, the speed-changing gear box power shaft links to each other with the drive motors rotating shaft with triangular driving band by belt pulley, also links to each other with the rotating hydraulic clamp shaft; Removable pallet arrangement comprises along lathe bed vertically to be done straight-line big palette and laterally does straight-line little supporting plate composition along lathe bed; The straight line that big palette is positioned on the lathe bed is led on the rule, and little supporting plate is positioned at the straight line that big palette is provided with leads on the rule; It is to be realized by the screw that the driven by servomotor screw mandrel on the lathe bed drives on the big palette downside that is installed on of numerical control device control that big palette is vertically done rectilinear motion along lathe bed; It is to be realized by the screw that the driven by servomotor screw mandrel on the big palette drives on the little supporting plate downside that is installed on of numerical control device control that little supporting plate is laterally done rectilinear motion along lathe bed; Establish electronics cutter platform on little supporting plate one side, it is characterized in that: on little supporting plate opposite side, set up formula milling cutter platform; Establishing synchronous pinion gear in the cutterhead rotating shaft of milling cutter platform is provided with synchronous gear wheel with the spline output shaft of speed-changing gear box and links to each other by synchronous cog belt; At the side of synchronous cog belt crimping expansion tightening wheel, expansion tightening wheel links to each other with the constant voltage cylinder piston rod.

Owing to adopt technique scheme, workpiece and milling cutter rotate simultaneously, big palette vertically moves along lathe bed, milling cutter platform on the little supporting plate and electronics cutter platform laterally move at big palette upper edge lathe bed, during processing work, earlier in the appearance and size programming input numerical control device according to workpiece, under the control of numerical control device, by two servomotors, the processing to workpiece is finished in the milling cutter work on control electronics cutter platform cutter and the milling cutter platform.Thereby have can compact conformation, manufacturing cost is lower, simple to operate, the efficient height, have the milling function concurrently, finish the processing of parts such as axial workpiece groove, side, straight-tooth, basin tooth, umbrella tooth and involute teeth automatically, and manufacturing procedure realizes automation, the machining accuracy height, calibration is accurate, the advantage that production cost is low.

Description of drawings: come the technical solution of the utility model is elaborated below in conjunction with the drawings and specific embodiments.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the right view of Fig. 1;

Fig. 3 is the vertical view of Fig. 1;

Fig. 4 is the A-A cutaway view of Fig. 3.

The specific embodiment: with reference to figure 1-Fig. 4, a kind of vertical numerical control turn-milling machine tool, form by rotating hydraulic anchor clamps and removable pallet arrangement that the clamping workpiece of lathe bed 1, drive motors, speed-changing gear box 2, numerical control device 3 and numerical control device control is used, speed-changing gear box 2 power shafts link to each other with the drive motors rotating shaft with triangular driving band by belt pulley, also link to each other with the rotating hydraulic clamp shaft; Removable pallet arrangement comprises along lathe bed vertically to be done straight-line big palette 4 and laterally does straight-line little supporting plate 5 compositions along lathe bed; Big palette 4 is positioned at straight line on the lathe bed leads on the rule 6, and little supporting plate 5 is positioned at the straight line that big palette 4 is provided with leads on the rule; It is that the servomotor 9 on the lathe bed of being installed on by numerical control device control drives the screw 17 that screw mandrels 10 drive on big palettes 4 downsides and realizes that big palette 4 is vertically done rectilinear motion along lathe bed; It is that the servomotor 11 on the big palette of being installed on by numerical control device control drives the screw 18 that screw mandrels 12 drive on little supporting plate 5 downsides and realizes that little supporting plate 5 is laterally done rectilinear motion along lathe bed; Establish electronics cutter platform 7 on little supporting plate 5 one sides, on little supporting plate 5 opposite sides, set up formula milling cutter platform 8; Establishing synchronous pinion gear in the cutterhead rotating shaft of milling cutter platform 8 is provided with synchronous gear wheel with the splined shaft output shaft 13 of speed-changing gear box 2 and links to each other by synchronous cog belt 14; At the side of synchronous cog belt 14 crimping expansion tightening wheel 15, expansion tightening wheel 15 links to each other with constant voltage cylinder 16 piston rods.On electronics cutter platform 7 cutterheads, be provided with many lathe tool, complexity according to workpiece processing, lathe tool is set number, as: the machine crossover sub is a conical surface band jump ring groove, the car conical surface and cylindrical are selected billmpse tool for use, car jump ring flowing current separation R lathe tool blocks with amputation knife at last, will be provided with 3 lathe tools on electronics cutter platform 7 cutterheads; Can be laid with manyly milling cutter on the cutterhead of milling cutter platform 8 according to the needs of the side of milling, as mill quadrangle and can all lay two milling cutters and finish, hexagon can all be laid three milling cutter finished.
