The invention realizes through following technical proposals: adopt the numerical control of electric main axle structure to be inverted vertical turning center, comprise lathe bed, column, guide rail, main spindle box, it is characterized in that: on lathe bed, be provided with X axle line slideway; Column moves before and after X axle line slideway is on lathe bed; On column, be provided with Z axle line slideway, main spindle box moves up and down on column along Z axle line slideway, and described main spindle box is bound up through angular contact ball bearing, cylinder roller bearing and built-in motor and mandrel; Be provided with pull bar in mandrel inside; The upper end of pull bar is connected with oil cylinder, and the lower end of pull bar is connected with chuck, and the cutter tower is fixedly mounted on the front portion of lathe bed, the below of chuck; The chain type pay-off passes lathe bed; On the chain type pay-off, be provided with several regular polygon fixed mounts, in the middle of the bottom of lathe bed, be provided with channel of chip removal, chip removal mouth is positioned at the lathe bed afterbody.
Described lathe bed is the enclosed construction of bridge-type symmetry.
C shaft locking device and circle grating are installed on the described main spindle box.
Z shaft locking slide block is installed on the described main spindle box.
Be connected with the nitrogen balance cylinder between described main spindle box and the column.
Lathe is provided with X axle linear grating chi and Z axle linear grating chi.
Lathe is provided with the contact Workpiece detecting device.
The beneficial effect of the invention: said structure is adopted in the invention, adopts inversion type electricity main shaft, and promptly the main spindle box upper end is provided with oil cylinder; The lower end is provided with chuck; Function through chuck realization manipulator cooperates the closed loop chain type pay-off that passes lathe bed, can accomplish the workpiece automatic loading and unloading; Automatically processing is easy to operate.Because chuck is positioned at the main spindle box lower end, makes chip removal more smooth and easy, has effectively improved the not smooth problem of digital control vertical turning center chip removal, avoid smear metal to scratch workpiece, guaranteed the machining accuracy of part.Chain type pay-off and lathe itself ideally combine, and the automatic loading and unloading stroke shortens, thereby the loading and unloading material time is short, and production efficiency is high.
Built-in motor driving main shaft case is adopted in the invention, than the traditional mechanical main shaft, has saved middle transmission link; Not only simple in structure, compact; Quality alleviates, and vibration, noise reduce, and the main shaft dynamic characteristic is better; The speed of mainshaft significantly improves, and piece surface crudy and working (machining) efficiency all have raising.Lathe bed adopts the enclosed construction of bridge-type symmetry, thus the stressed symmetry of lathe, uniform heat distribution, quiet dynamic stiffiness is high.When the cutter tower of configuration is power cutter tower, C shaft locking device and circle grating are installed on the main spindle box, realize the directed locking of C axle.Z shaft locking slide block is installed on main spindle box, is realized Z shaft locking, the location, the milling of fixing a point improves crudy.
