The two V-blocks 420 have V-grooves 421 on their facing sides. The tail ejector assembly 500 includes an ejector clamping component 510 and an ejector 520. The ejector clamping component 510 is connected to the mounting backplate 100, and the ejector 520 is clamped thereto. The tip of the ejector 520 faces upward and is coaxial with the output shaft of the drive assembly 300. The assembly to be cleaned 700 includes a nut assembly 710 and a ball screw 720 to be cleaned. The two V-blocks 420 can clamp the nut assembly 710. The ball screw 720 to be cleaned mates with the nut assembly 710. The top end of the ball screw 720 to be cleaned is connected to the output shaft of the drive assembly 300, and the bottom end abuts the tip of the ejector 520. One end of the oil pipe 600 is connected to the oil tank 200, and the other end is located near the connection between the ball screw 720 to be cleaned and the nut assembly 710. The cleaning oil in the oil tank 200 is pumped into the oil pipe 600 by the oil pump. The program controls the number of times, the oil pump is turned on, and the cleaning oil is drawn out from the oil tank 200 and flows out of the oil pipe 600 to the ball screw 720 to be cleaned.

[0039] The control is started, and the ball screw 720 to be cleaned rotates with the driving assembly 300 to make the nut assembly 710 run up and down, thereby grinding off burrs and dirt, which then flow away with the cleaning oil.

[0040] Specifically, in this embodiment, the nut assembly 710 is clamped between two V-blocks 420, and the drive assembly 300 rotates the ball screw 720 to be cleaned, causing the nut assembly 710 and the automatic adjustment clamping assembly 400 to move up and down.
