Further, Z-direction main spindle box body has shell, main shaft, knife striking cylinder, main motor and the chuck matching with main shaft and cutter, main motor drive shaft rotation, and knife striking cylinder is arranged on shell so that chuck and cutter that handling match with main shaft.
Further in order to realize electrodeless variable-speed function so that numerical control drilling machine also possesses bore hole, tapping and Milling Function except possessing drilling function, described main shaft is BT-40 main shaft or BT-50 main shaft.
Further for balance Z-direction main spindle box body in Z-direction main spindle box body moving process makes its motion steadily to increase its machining accuracy, on described column, be also provided with bascule, bascule comprises equilibrate counterweight, balance rope and pulley assembly, pulley assembly is arranged on column, one end and the Z-direction main spindle box body of described balance rope are fixedly connected, and the other end of described balance rope is flexibly connected with pulley assembly afterwards and equilibrate counterweight is fixedly connected.
Adopted after technique scheme, Z-direction servomotor rotation of the present utility model, drive the rotation of Z-direction ball-screw, drive nut Z-direction moves, make Z-direction main spindle box body under the guide effect of Z-direction linear rolling guide, also follow Z-direction to move, finally make Z-direction main spindle box body Z-direction move, thereby can increase the Z-direction shift motion of Z-direction main spindle box body, increase the range of work of workpiece, in addition, not only coefficient of friction is little for the Z-direction linear rolling guide that the utility model adopts, be about 1/10 of rigid rail plate, it is very little that the gap of kinetic force of friction and stiction also becomes, therefore when Z-direction main spindle box body moves, not having the phenomenon of skidding occurs, can reach the positioning precision of 0.001 millimeter, because Z-direction rolling linear guide friction force is very little, only need smaller power (being about motive 1/8) just can make the operation of Z-direction main spindle box body, obviously reduced power consumption amount, greatly saved workpiece processing cost.Thereby increased economic benefit.
Accompanying drawing explanation
Fig. 1 is the structural representation of the Z-direction main shaft device for numerical control drilling machine of the present utility model.
The specific embodiment
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail below.
As shown in Figure 1, a kind of Z-direction main shaft device for numerical control drilling machine, it comprises Z-direction servomotor 1, Z-direction ball-screw 7, drive nut 7-1, Z-direction main spindle box body 11, Z-direction linear rolling guide 6 and column 5, Z-direction servomotor 1 is flexibly connected with Z-direction ball-screw 7 by transmission mechanism to drive 7 rotations of Z-direction ball-screw, Z-direction ball-screw 7 can be rotated to support on column 5, drive nut 7-1 is movably connected on Z-direction ball-screw 7 by screw thread, Z-direction main spindle box body 11 is fixedly connected with drive nut 7-1, Z-direction linear rolling guide 6 is arranged between column 5 and Z-direction main spindle box body 11.
Chuck and cutter that Z-direction main spindle box body 11 has shell 11-1, main shaft 10, knife striking cylinder 9, main motor 8 and matches with main shaft 10, main motor 8 drive shaft 10 rotations, knife striking cylinder 9 is arranged on shell so that chuck and cutter that handling match with main shaft.
