Moving column type numerical control processing centre

Abstract

The invention relates to a numerical control processing centre belonging to the technical field of numerical control machine tool structures. The moving column type numerical control processing centre comprises a work bench for mounting workpieces; the work bench is provided with a transverse stand column which is provided with a cross-shaped slide base; the upper end of the cross-shaped slide base is connected with a Y-axis screw rod and the lower end is connected with an X-axis screw rod; a longitudinal stand column capable of moving up and down along a vertical ram is arranged on the upper part of the Y-axis screw rod and is connected with a Z-axis screw rod; and the lower end of the vertical ram is connected with a spindle with a cutter. As workpieces are statically mounted on the work bench during processing, compared with the traditional machine tool, the moving column type numerical control processing centre has the following advantages: 1, cut sweeps, cooling liquid, and the like can not contact the moving parts of the machine tool, thereby prolonging the service life of the machine tool; 2, the workpieces can be mounted in different areas to realize continuous processing; and 3, the machine tool with the same processing range can save castings by 30-40% compared with the traditional machine tool, and large-scale machine tools are more obvious in saving.

Description

technical field [0001] The invention relates to a numerical control machining center, which belongs to the technical field of numerical control machine tool structures. Background technique [0002] At present, traditional CNC milling machines such as figure 2 As shown, it has the advantages of high machining accuracy and high machining efficiency compared with ordinary milling machines, but the existing CNC milling machines also have the following problems: because the workpiece also moves with the moving part of the machine tool during the machining process, resulting in After cutting, waste chips, coolant, etc. will be scattered on the machine tool, which is not only troublesome to clean up, but also shortens the service life of the machine tool, and the weight of the workpiece will also affect the accuracy of the machine tool, which eventually leads to the failure of the processed workpiece to achieve higher accuracy requirements.
