The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present invention are described in detail explanation.

Integral layout of the present invention: this device belongs to cross slide column type main shaft inversion type turnning and milling complex machining device.Lathe bed 21 horizontal positioned, lathe bed 21 head rail faces are installed X to linear guides pair 10.Select the ball-screw transmission for use between two linear guides, X is installed on lathe bed 21 left sides to servomotor 12, drives the ball-screw rotation by the plum blossom shaft coupling.

Slide plate 18 is installed on X on linear guides pair 10, and slide plate 18 head rail faces are installed Y to linear guides pair 17.Select the ball-screw transmission for use between two linear guides, Y is installed on slide plate 18 rear sides to servomotor 19, drives the ball-screw rotation by the plum blossom shaft coupling.Slide plate 18 bottoms are connected with nut seat and whole link to ball screw assembly, with X, at X to the driving lower edge of servomotor 12 X to linear guides left and right sides high-speed mobile.

Column saddle 16 is installed on Y on linear guides pair 17, and saddle 16 middle chambers are installed balancing weight 15.Weighting system chain-wheel mechanism 13 is installed at saddle 16 tops, balancing weight 15 left and right sides are Weighting system guide rail mechanisms 14, saddle 16 front side rail faces are installed Z and are selected for use Z to ball screw assembly, 6 transmissions between linear guides pair 4, two guide rails, and Z is installed on saddle 16 top front to servomotor 7.Saddle 16 bottoms are connected with nut seat and whole link to ball screw assembly, 20 with Y, at Y to the driving lower edge of servomotor 19 Y to the secondary 17 front and back high-speed mobile of linear guides.

The left side square opening of main spindle box 8 is installed inverted main motor 9, the right side centre bore is installed inverted main axle unit 2, angling cylinder 5 is installed in inverted main axle unit 2 upper ends, and oild chuck 1 is installed in inverted main axle unit 2 lower ends, and inverted main axle unit 2 replaces manipulator and realizes taking, putting material.The front side Plane Installation encoder 3 of main spindle box 8, on encoder 3 and inverted main axle unit 2, inverted main axle unit 2 and the main motor 9 synchronous pulley is installed, by high efficiency synchronous band transmission campaign, realize that oild chuck 1 around 360 ° of rotations of Z axle, forms the C axle.The back plane of main spindle box 8 is connected with nut seat and integral body links with ball-screw, moves up and down to linear guides pair 4 along Z under the driving of servomotor 7 at Z.

Power cutter tower 11 is installed on the lower-left side of lathe bed 21, and dynamic tool apron is driven by the direct current generator of power cutter tower, produces relative cutting movement with cutter when the cutter rotation is moved workpiece, carries out Milling Process at the end face and the arc surface of workpiece.During processing work, the workman is at charging position place work piece blank, and rotation top layer pallet lock clamping of workpieces, be transported to the material loading position after, to system, system stops feed mechanism motor and decelerator motion to the feed mechanism travel switch with signal feedback.And send instruction simultaneously and give X to servomotor 12, driving ball screw assembly, drive slide plate 18 and move right, slide plate 18 drives saddles 16 and main spindle box 8 moves together.After arriving appointment material loading position, sending instruction gives Y to servomotor 19, driving Y moves forward and backward to ball screw assembly, 20 drive saddles 16, the position of centering material loading is also sent instruction simultaneously and is moved down for Z to servomotor 7 driving Z to ball screw assembly, 6 drive main spindle boxes 8, in this process, open oild chuck 1 claw, aim at the material loading pallet body, workpiece is compressed and closed chuck 1 grabbing workpiece, material grasping carries out turning according to the processing program order that weaves in advance then to the machining area at power cutter tower 11 places, milling, boring, bore hole or turnning and milling Compound Machining.After finishing processing, inverted main axle unit 2 carries the part that processes and is back to the material loading position along X to former road, unclamps the workpiece that oild chuck 1 puts down completion of processing.Send instructions then to the feed mechanism motor, move the supreme material level of workpiece blank of next station clockwise and put, operation is finished the processing of next workpiece before repeating.In the blanking position, artificial assisting taken off the workpiece of completion of processing, and puts new workpiece blank and carry out next batch processing.So far, the present invention finishes whole manufacturing procedures.
