[0024] Working process: When the device is in use, the external power supply is energized. When the device needs to be processed, the part is fixed at the upper end of the mold plate 11, and the electric telescopic rod 3 is started. The electric telescopic rod 3 pulls the T-plate 4 to move downward, and the T-plate 4 drives the processing equipment to move downward. At the same time, the movement of the T-plate 4 drives the rectangular slide plate 5 to move. The rectangular slide plate 5 is slidably connected to the inner side of the square slide groove 14. According to the shape of the rectangular slide plate 5 and the square slide groove 14, the rectangular slide plate 5 is limited when it moves. The movement of the rectangular slide plate 5 drives the column slide 6 fixed at the upper end to move downward. The shape is "L"-shaped, which is convenient for pulling the column slide 6 to move. The column slide 6 drives the spring telescopic rod 10 fixed at the upper end to move, and the spring telescopic rod 10 drives the mold plate 11 fixed at the upper end to move. The mold plate 11 is slidably connected to the inner side of the rectangular concave slide 18 through the limiting ear seat 12. A gap is provided between the limiting ear seat 12 and the blocking groove 17. The rectangular concave slide 18 has the effect of limiting the movement of the limiting ear seat 12. At the same time, the distance opened by the rectangular concave slide 18 is limited. When the limiting ear seat 12 slides to the bottom of the rectangular concave slide 18, the mold plate 11 stops moving, and the mold plate 11 The spring telescopic rod 10 is moved inside the blocking groove 17, and the spring arranged inside the spring telescopic rod 10 keeps the spring telescopic rod 10 in a contracted state. When the limiting ear seat 12 touches the bottom end of the rectangular concave slideway 18, the T-plate 4 continues to move downward. At this time, the processing equipment at the lower end of the T-plate 4 contacts the workpiece and can be processed. After the processing is completed, according to the above principle, the electric telescopic rod 3 is started to drive the T-plate 4 to move upward, and the spring telescopic rod 10 pushes the mold plate 11 to move upward, so that the workpiece can protrude from the upper end of the machine tool worktable 1, which is convenient for loading and unloading. When cleaning the interior, when the column slide 6 moves upward, the first check valve 9 inside the first port 8 is in an open state, and the sealing ring 7 seals the column slide 6 and the machine tool worktable 1. At the same time, the second solenoid valve 16 inside the second through hole 15 is in a closed state. When the column slide 6 moves downward, the first check valve 9 is closed and the second solenoid valve 16 is opened. At this time, the splashes inside the blocking groove 17 enter the second through hole 15 from the blocking groove 17, enter the first port 8 from the second through hole 15, and then enter the column groove 13, thereby achieving the effect of cleaning the splashes.
