[0025] In the technical scheme (as shown by Figure 1 、 Figure 2 and Figure 3As shown), the translation mechanism includes a rotating lead screw 41. The rotating lead screw 41 is rotatably installed inside each hollow frame 4 via a bearing. A servo motor 42 is fixedly installed on the outside of each hollow frame 4, and the side of the transmission shaft of the servo motor 42 is fixedly connected to the top of the side of the rotating lead screw 41. A transmission sleeve 43 is threadedly fitted onto the outside of each rotating lead screw 41. A transmission block 44 is fixedly installed on the side of each transmission sleeve 43, and the top of the side of the transmission block 44 is fixedly connected to the outside of the sliding table 2. A limit groove 45 is opened inside the side of each hollow frame 4, and the transmission block 44 is slidably inserted into the limit groove 45.
[0026] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), an installation frame 11 is fixedly installed on the top side of the mounting platform 1. Hydraulic cylinders 12 are vertically fixedly installed on both sides of the top of the mounting frame 11. A pressing block 13 is slidably installed on the top inner side of the mounting frame 11.
