The setting of the inspection door 102 makes it convenient to add lubricating oil to the oil barrel 601.

[0031] Working principle: When the device is in use, the product is processed through the longitudinal moving mechanism 3, the fixing mechanism 201, the transverse moving mechanism 4, the vertical moving mechanism 5 and the engraving and milling mechanism 7. The oil barrel 601 is filled with viscous lubricating oil. When the first guide rod 401 and the second guide rod 505 of the transverse moving mechanism 4 and the vertical moving mechanism 5 need to be added with lubricating oil, the sliding block 404 is controlled to move to one side of the L-shaped baffle 607 so as to squeeze the L-shaped baffle 607. When the L-shaped baffle 607 moves with the cross bar 608, the blocking column 609 can limit the round rod 612. Since the round rod 612 is blocked by the block 613 and cannot rotate, the round rod 612, the rotating block 616, the square rod 610 and the piston 611 move, so that the internal lubricating oil reaches the first oil receiving pipe 407, the second oil receiving pipe 504, etc. through the hose, thereby lubricating the first guide rod 401 and the second guide rod 505. When the sliding block 404 is away from When the L-shaped baffle 607 is in operation, the L-shaped baffle 607 and the cross bar 608 are reset under the action of the reset spring 617. At this time, the stop column 609 drives the round rod 612 to rotate toward one side of the V-shaped spring piece 615, so that the piston 611 does not move. When the cross bar 608 does not move, the round rod 612 contacts the stop block 613 again under the action of the V-shaped spring piece 615, waiting to work again. In this way, when lubricating oil needs to be added, the L-shaped baffle 607 is squeezed by the sliding block 404. , each time the piston 611 approaches one side of the tee head 603, it can be added. The lubricating oil entering the sliding block 404 and the lifting block 503 can also lubricate the inside of the screw nut. When the lubricating oil is consumed, the control valve 604 can be closed, the sealing cover on the top of the oil filling pipe 602 can be opened, and the lubricating oil can be squeezed into the oil barrel 601 through the lubricating oil adding tool. At the same time, the round rod 612 is moved to one side of the V-shaped spring piece 615 to facilitate the movement of the piston 611.
