Abstract

The invention discloses a numerical control machine tool which comprises a rack. The rack is provided with a workbench, a screw driving the workbench to move horizontal and a motor driving he screw torotate. The workbench is provided with an installing block connected with the screw, the rack is provided with a cooling mechanism for cooling the screw, the cooling mechanism comprises an oil storage cavity formed in the installing block and an oil return groove formed below the screw, the oil storage cavity is used for storing cooling oil, the oil storage cavity is provided with an oil draininghole facing the screw, and the oil return groove is used for collecting cooling oil dripping down from the screw. According to the numerical control machine tool, the screw driving the workbench to move can be cooled, and meanwhile the strength of the screw is not lowered.

Description

technical field [0001] The invention relates to machining equipment, in particular to a numerically controlled machine tool. Background technique [0002] In the prior art, a numerically controlled machine tool is a kind of high-efficiency machining equipment, which is usually used for cutting, milling, drilling and tapping of metal parts. [0003] Generally, the structure of a CNC machine tool mainly includes a frame. The frame is provided with a spindle and a worktable. The spindle is used to fix machining tools. The workbench is arranged below the spindle. The main shaft can rotate and move up and down, and the table can move horizontally. The direction of horizontal movement is two mutually perpendicular directions, which are usually defined as the X axis and the Y axis, and the main shaft is defined as the Z axis. [0004] The structure that replaces the movement of the worktable is usually a screw and a motor. When the screw drives the worktable to move, it will gener...
