[0002] CNC machine tools are digitally controlled machine tools, which are automated machine tools equipped with a program control system. After calculation and processing, the CNC device sends out various control signals to control the movement of the machine tool. It automatically processes parts according to the shape and size required by the drawing. CNC machine tools with different numbers of axes have different performances.

[0003] A spindle lifting mechanism disclosed in the Chinese utility model patent application specification CN203449118U has a simple structure and is easy to maintain. When the spindle is lifted or lowered, the force on the screw rod can be balanced and the lifting accuracy is high. However, it is unable to effectively clean chips from the drill bit during use, which affects work efficiency. At the same time, it is unable to lift or lower the spindle and perform horizontal displacement operations. Therefore, a spindle lifting mechanism for a CNC machine tool is proposed.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By starting the first motor, the threaded rod is driven to rotate. At this time, under the action of the limit rod and the limit block, the moving block can be moved vertically up and down along the surface of the threaded rod, thereby driving the bearing plate to move up and down. At the same time, the driving motor is started to drive the screw rod to rotate. Because the moving plate fits the inner wall of the moving groove, the moving plate can be horizontally displaced along the surface of the screw rod, driving the fixed plate to move accordingly. This setting can effectively adjust the horizontal position and height position of the drill bit according to different production needs, so that the overall equipment can quickly adjust the spindle position, which is convenient for the staff to operate and use.

[0014] 2. By starting the driving motor, the screw is driven to rotate. At this time, since the movable plate fits against the inner wall of the movable groove, the movable plate can be moved horizontally along the surface of the screw, thereby driving the mounting frame and the chip removal fan outside the movable plate to move accordingly. Since the distance between the movable plate and the movable plate remains unchanged, the chip removal fan and the mounting frame can always maintain the best position between the drill bit. At the same time, under the action of the chip removal fan, the drill bit can be effectively blown to remove chips, effectively preventing the debris generated during work from affecting the drill bit.
