[0023] See also Figure 1 , Figure 2 and Figure 3 The lubrication mechanism 14 includes a box body 17, which is fixedly connected to the top of the horizontal plate 1. The front side of the box body 17 is connected to an oil filling valve 18, and the front side of the oil filling valve 18 is connected to a telescopic hose 19. The bottom of the telescopic hose 19 passes through the moving block 9. By arranging the box body 17, the oil filling valve 18 and the telescopic hose 19, the surface of the threaded rod 8 can be lubricated, so that the movement of the moving block 9 is smoother, which is beneficial to the positioning process. The output end of the controller 16 is electrically connected to the oil filling valve 18 in one direction.

[0024] See also Figure 4An auxiliary block 20 is fixedly connected to the right side of the top of the threaded rod 8. By setting the Hall sensor 15 and the auxiliary block 20, the number of rotations of the threaded rod 8 can be detected, so that oil can be injected in time. The threads on both sides of the surface of the threaded rod 8 have opposite rotation directions.

[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 The front side of the top of the horizontal plate 1 is connected to an electric push rod 21 through a mounting plate. The output end of the electric push rod 21 passes through the inner cavity of the chip collecting bucket 12 and is connected to an inclined plate 22 through bolts.
