An automated CNC machine tool

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 is composed of a drilling process, a chamfering process and a tapping process. For products with general accuracy requirements, you can directly use a drilling machine or CNC machining center to complete 1 drilling 2 chamfering 3 tapping; for higher accuracy requirements, you can add 1 center drilling positioning hole 2 drilling 3 inversion before drilling Angle 4 tapping such steps. [0003] For precision, generally large batches of porous drilling and tapping can be used 1 fixed multi-axis device to directly drill, the workpiece is moved or transported to the tapping station 2 fixed multi-axis device to directly tap. [0004] For multi-axis drilling and tapping with high precision requirements and large production batches, 1 drillin...

AI Technical Summary

Problems solved by technology

[0007] If the traditional multi-axis drilling and tapping does not use the template guide, there will be a large hole position deviation, which will easily lead to the damage of the tap and cause the workpiece to be scrapped. When the workpiece is removed from the drilling template and then moved to the tapping station, there are secondary clamping errors and it is not easy to realize automatic processing
