A New Type of CNC Machine Tool for Multi-axis and Multi-surface Machining

Abstract

The invention relates to the field of numerical control machine tools, in particular to a novel numerical control machine tool with a multi-axial polyhedral machining function. The novel numerical control machine tool comprises a machine tool base, a machining cross beam, a longitudinal machine head and a transverse machine head, wherein X-axis rails, Y1-axis rails and Y2-axis rails are arranged on the upper surface of the machine tool base; the machining cross beam and the transverse machine head are correspondingly arranged on the Y1-axis rails and Y2-axis rails in a sliding manner; Z-axis rails are arranged on the cross beam; the longitudinal machine head is arranged on the Z-axis rails in a sliding manner; each of the longitudinal machine head and the transverse machine head is provided with a machining spindle. According to the contents, the invention provides the novel numerical control machine tool which comprises the transverse machine head and the longitudinal machine head; the machining spindles arranged on the transverse machine head and the longitudinal machine head can be used for simultaneously machining workpieces; the motions of the two machine heads and the machining spindles which are correspondingly arranged on the two machine heads, on the machine tool base, are relatively independent, so that the two machine heads can be separately controlled or coordinately controlled to simultaneously machine the workpieces, and the machining control of the numerical control machine tool is more diversified, high flexibility is obtained, and further the numerical control machine tool is higher in machining efficiency and wider in application range.

Description

Technical field [0001] The invention relates to the field of numerical control machine tools, in particular to a novel multi-axis and multi-faceted numerical control machine tool. Background technique [0002] Most traditional CNC machine tools have only one machining spindle. In order to use one spindle to achieve multi-face machining, a rotary device such as an indexing plate is installed on the spindle installation structure to change the machining direction of the spindle. However, this processing method makes the positioning process of the spindle after switching the processing plane extremely complicated. For example, after the spindle has finished processing a horizontal upper surface, to switch to a certain point on the vertical side to start processing, the spindle needs to retract the tool first, then rotate a certain angle, and then move through the X, Y, and Z axes. Positioning to a certain point on the side for processing, and the error of this tool setting is large...

Problems solved by technology

However, this kind of multi-axis CNC machine tool cannot use the additional spindle to process multiple surfaces of the workpiece at the same time. It only increases the processing efficiency to a certain extent and cannot meet the processing needs of more parts.
