Vertical machining centre machine tool

Abstract

The invention discloses a vertical machining centre machine tool which comprises a base horizontally arranged on the ground. A lathe bed is arranged on the base, a workbench capable of doing horizontal progressive rotation is arranged on the side, on the lathe bed, of the base, a vertical column is arranged on one side of the lathe bed, a cross-shaped sliding plate horizontally arranged on the lathe bed is arranged at the connecting position of the vertical column and the lathe bed, and a spindle wrapping a spindle box is arranged on one side of the vertical column. The spindle box can vertically move along the vertical column in the Z-axis direction. The vertical column can horizontally move along the cross-shaped sliding plate in the Y-axis direction. The cross-shaped sliding plate can horizontally move along the lathe bed in the X-axis direction, and the vertical machining centre machine tool is provided with an automatic tool switching system. According to the technical scheme, the vertical machining centre machine tool can move in three-dimensional space, the automatic tool switching system achieves automatic tool switching of the machine tool, and machining efficiency and machining precision are improved. The defects that a workbench in the prior art participates in feeding motion under the condition of loads, the loads of the workbench are different, and the feeding speed and response time of the machine tool are influenced are overcome.

Description

Technical field [0001] The present invention belongs to the field of mechanical manufacturing. More specifically, the present invention relates to a vertical machining center machine tool. Background technique [0002] The structure of the vertical machining center machine tool is diverse.

[0002] The structure of the vertical machining center machine tool is various. The structure of the vertical machining center machine tool in the prior art mainly includes fixed column dynamic table type, moving column dynamic table type, small gantry type and other structures. These structures are in the process of processing The workpieces are all involved in feeding, so this structure has a direct or indirect impact on the acceleration performance of the machine tool; at the same time, the machine tool with this structure directly affects the speed, acceleration, accuracy and life of the machining operation; the above-mentioned vertical machining center machine tools The existing problems of the structure: 1) The workbench participates in the feed movement under the load, and the different loads of the workbench affect the speed and reaction time of the machine tool when it is fed; 2) The guide rail and the feed system with moving parts at the bottom of the workpiece , the quality of the guide rail and the protection of the feed system will also directly affect the machining accuracy and service life of the machine tool; 3) The machine tool must be stopped during the process of processing workpieces up and down; it is difficult to realize continuous processing of workpieces, which reduces the working efficiency of vertical machining center machine tools ; The vertical machining center machine tools of the prior art must also improve the protection ability of the machine tool, increase the cost of equipment use, and reduce the speed and reaction time of the machine tool when it is fed
