Digital controlled drill

Abstract

The invention discloses a digital controlled drill which comprises a base, a Y-oriented servo motor, a Y-oriented rolling linear guide rail pair, a Y-oriented ball screw, a Y-oriented drive nut, a Y-oriented sliding table, an X-oriented servo motor, an X-oriented rolling linear guide rail pair, an X-oriented ball screw, an X-oriented drive nut, a working table, a Z-oriented servo motor, a Z-oriented ball screw, a drive nut, a Z-oriented main shaft box, a Z-oriented rolling linear guide rail pair and a stand column. The stand column is installed on the base, the Z-oriented servo motor is movably connected with the Z-oriented ball screw through a transmission mechanism so as to drive the Z-oriented ball screw to rotate, the Z-oriented ball screw is rotatably supported on the stand column, the drive nut is movably connected to the Z-oriented ball screw through threads, the Z-oriented main shaft box is fixedly connected with the drive nut, the Z-oriented rolling linear guide rail pair is arranged between the stand column and the Z-oriented main shaft box, and the working table is located below the Z-oriented main shaft box. According to the drill, moving strokes can be increased in the X direction, the Y direction and the Z direction, the machining range of workpieces is widened, meanwhile, the electric power loss amount can be reduced, cost is saved, and precise positioning and machining of the workpieces can be achieved.

Description

technical field [0001] The invention relates to a numerically controlled drilling machine, which belongs to the technical field of drilling machines. Background technique [0002] At present, the main function of the CNC drilling machine in the existing technology is mainly drilling, and the milling and tapping functions are difficult to realize, and the rigid sliding guide rail is used. Oil, if the lubrication is insufficient, it will cause direct friction of the metal on the contact surface and wear the bed. Moreover, the Z-direction spindle box of the original CNC drilling machine cannot move freely up and down in the Z-axis direction, and only relies on the movement of the Morse spindle to move up and down. The Z-axis stroke is only 240mm, and the Z-axis stroke is limited. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a numerical control drilling machine, which can...

[0002] At present, the main function of the CNC drilling machine in the existing technology is mainly drilling, and the milling and tapping functions are difficult to realize, and the rigid sliding guide rail is used. Oil, if the lubrication is insufficient, it will cause direct friction between the metal on the contact surface and wear the bed

Moreover, the original CNC drilling machine's Z-direction spindle box cannot move freely up and down in the Z-axis direction, and only relies on the movement of the Morse spindle to move up and down. The Z-axis stroke is only 240mm, and the Z-axis stroke is limited.
