Abstract

The invention belongs to the technical field of numerically-controlled machine tools, and provides an automatic numerically-controlled machine tool. The automatic numerically-controlled machine tool comprises a machine tool; stand columns are arranged at the two ends of the machine tool, a transverse guide rail, a first lead screw and a first motor are arranged on the stand columns, the transverseguide rail is parallel to the first lead screw, and the first motor is connected to the first lead screw; a transverse moving platform is arranged on the transverse guide rail, the first lead screw is connected to the transverse moving platform through a nut, and a longitudinal guide rail, a second lead screw and a second motor are arranged on the transverse moving platform; and a longitudinal moving platform is arranged on the longitudinal guide rail, the second lead screw is connected to the longitudinal moving platform through a nut, a clamping device used for fixing a workpiece is arranged on the longitudinal moving platform, and the second motor is connected to the second lead screw. The technical problems that in existing traditional multi-shaft drilling and tapping, if a drill jigguider is not adopted, the hole position degree deviation is large, a screw tap is prone to being damaged, and then a workpiece is scrapped; and if the drill jig guider is adopted, secondary clampingerrors exist and automatic machining is inconvenient to achieve due to technology reasons are solved.

Description

technical field

[0001] The invention belongs to the technical field of numerical control machine tools and relates to an automatic numerical control machine tool. Background technique

[0002] At present, most of the drilling and tapping in machining are composed of drilling process, chamfering process and tapping process. For products with general precision requirements, it can be completed by drilling machine or CNC machining center directly by 1 drilling, 2 chamfering and 3 tapping; for those with high precision requirements, 1 center drilling positioning hole 2 drilling 3 tapping can be added before drilling Angular 4 tapping such steps.

[0003] For the precision general production volume of large multi-hole drilling and tapping, 1 fixed multi-axis device can be used to directly drill holes, and the workpiece is moved or transported to the tapping station 2 Fixed multi-axis device directly taps the teeth.

[0004] For multi-hole drilling and tapping with high precisio...
