By setting the screw rod 19 and the second connecting block 22 as a transmission connection mechanism, the spindle box 12 and the machining mechanism 13 can be driven to move up and down stably, thereby meeting different machining requirements.

[0018] A groove 23 is formed inside the second connection block 22 , and a plurality of steel balls 24 are filled in the groove 23 . The first connection block 14 is sleeved on the guide rod 2 , and the end of the screw rod 19 is connected to a motor 21 .

[0019] By filling the groove 23 of the second connecting block 22 with steel balls 24, the steel balls 24 are matched and filled in the arc groove on the side of the screw rod 19. When the device is running, the design of the steel balls 24 can avoid direct friction between the screw rod 19 and the second connecting block 22, thereby reducing the possibility of friction damage between the second connecting block 22 and the screw rod 19, ensuring the stability of the transmission mechanism and effectively improving the operating life of the equipment.

The spring 18 plays a certain buffering and protective effect, which can prevent the main shaft box 12 from falling too fast and causing vibration problems.

[0022] In the above solution, a dust cover 25 is provided on the side of the processing mechanism 13, and the dust cover 25 is connected to the collection box 27 through a hose 26. A suction fan 28 is provided on the side of the collection box 27. Specifically, when the equipment is running, a negative pressure is formed at the opening of the dust cover 25 by the suction fan 28, so that the dust and debris impurities generated during processing are sucked into the collection box 27 through the dust cover 25 and the hose 26 for storage. Furthermore, a filter is provided in the collection box 27 to prevent debris from entering the suction fan 28.

[0027] For this type of vertical machining center output balancing device, when it is necessary to adjust the height of the spindle box 12, the user starts the motor 21 through an external switch, and the output end of the motor 21 drives the screw 19 to rotate through the reducer, and the second connecting block 22 connected to it is driven by the screw 19 to drive the spindle box 12 to move up and down. In this process, under the guidance of the limit rod 17 and the guide rod 2, the stability of the spindle box 12 during movement is guaranteed, and the jitter and offset phenomenon during the equipment adjustment process is reduced.
