Single-head/double-head composite numerical control machine tool

Abstract

The invention belongs to the technical field of numerical control machine tools, and particularly relates to a single-head / double-head composite numerical control machine tool. The single-head / double-head composite numerical control machine tool comprises a base, a workbench movably arranged on the upper part of the base and a portal frame arranged on the base, wherein theportal frame is located on the upper part of the workbench; and the machine tool further comprises a first sliding rail arranged on the portal frame, a first lead screw, a second lead screw, a first machine head, a second machine head, a first X-Y-axis driving device for driving the first lead screw to rotate, a second X-Y-axis driving device for driving the second lead screw to rotate, a first Z-axis driving device for driving the first machine head, a second Z-axis driving device for driving the second machine head and a control module, wherein the first lead screw and the second lead screw are rotatably arranged, and the first machine head and the second machine head are arranged on the first sliding rail in a sliding mode. The two machine heads of the single-head / double-head composite numerical control machinetool can be controlled to move respectively, the structure is simple, the working efficiency can be improved, and the occupied area and the production cost can be saved.

Description

technical field [0001] The invention belongs to the technical field of numerical control machine tools, and in particular relates to numerical control machine tools for processing precision workpieces in various industries. Background technique [0002] The purchase cost of high-precision CNC machine tools is relatively high. At present, the control machine tools on the market include single-head and double-head processing CNC machine tools. Single-head CNC machine tools are easy to control product accuracy, but have the defect of slow processing efficiency; The two processing heads can only run synchronously, and the size range of the processed workpieces is limited by the effective stroke of the machine tool, and can only process workpieces smaller than 1 / 2 of the worktable, which cannot be used for large-sized workpieces. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the object of the present invention is to...
