[0028] Please refer to Figures 1-3 The lower pressing assembly comprises a hydraulic cylinder 3, the hydraulic cylinder 3 is arranged on the machining table 2, and a lower pressing plate 4 is arranged on the telescopic rod of the hydraulic cylinder 3.

[0029] The hydraulic cylinder 3 is started, the hydraulic cylinder 3 drives the lower pressing plate 4 to lift through the telescopic rod, and the lower pressing plate 4 is lowered and pressed above the slider body 5.

[0030] Please refer to Figures 3-5 A top block 7 for limiting the front and back positions of the slider body 5 on one side is arranged on the lifting platform 6, and a baffle for limiting the left and right positions of the slider body 5 on one side is arranged on the machining table 2.

[0031] The slider body 5 is pushed onto the lifting platform 6, one side of the slider body 5 is in contact with the baffle, one end of the slider body 5 is pushed to the top block 7, and the slider body 5 is limited by the top block 7 and the baffle.

[0032] Please refer to Figures 3-5 The transmission assembly comprises a first limiting rod 8, the first limiting rod 8 is arranged on the lifting platform 6, one end of the first limiting rod 8 away from the lifting platform 6 is slidably connected with the machining table 2, a first spring 9 is sleeved on the first limiting rod 8, the transmission assembly further comprises a first plug rod 10, the first plug rod 10 is arranged on the lifting platform 6 and is inserted into a first oil cavity prearranged on the machining table 2, the transmission assembly further comprises a second limiting rod 12, the second limiting rod 12 is arranged in a second oil cavity prearranged on the machining table 2, a second spring 13 is sleeved on the second limiting rod 12, a second plug rod 15 is sleeved on the second limiting rod 12, an extrusion plate 14 is arranged on the second plug rod 15, the first oil cavity and the second oil cavity are communicated with each other through a communication pipe 11, a fixing block 16 for plugging the opening above the second oil cavity is arranged on the machining table 2, a sleeve block 17 is sleeved on the fixing block 16, the second plug rod 15 passes through the fixing block 16 and is connected with the sleeve block 17 (wherein a sealing ring is arranged inside the hole of the fixing block 16 through which the second plug rod 15 passes, for preventing leakage of hydraulic oil), the side clamp comprises a transmission block 18, a side pressing block 19 and a limiting block 20, the transmission block 18 is arranged above the sleeve block 17, the side pressing block 19 is slidably connected with the machining table 2, the limiting block 20 is fixedly installed on the machining table 2, and the transmission block 18 is slidably connected with the side pressing block 19 and the limiting block 20 respectively.

[0033] When the lifting platform 6 descends, it will cause the first limiting rod 8 and the first insert rod 10 to descend, simultaneously compressing the first spring 9. A piston is located at the lower end of the first insert rod 10. As the first insert rod 10 descends, it squeezes the hydraulic oil inside the first oil chamber, forcing it through the connecting pipe 11 into the second oil chamber. The increased hydraulic oil in the second oil chamber pushes downwards against the extrusion plate 14. The extrusion plate 14 then moves the second insert rod 15 downwards along the second limiting rod 12. At this time, the second spring 13 is compressed. A sealing ring is provided on the extrusion plate 14 to maintain contact with the inner wall of the second oil chamber. The second insert rod 15 presses down and pulls the sleeve block 17 downwards. The fixing block 16 is fixedly installed on the processing table 2, blocking the opening above the second oil chamber to prevent hydraulic oil leakage. The sleeve block 17 will not move the fixing block 16. The sleeve block 17 is fixedly connected to the transmission block 18, which has a sloping surface on one side. The other side is a straight surface. The inclined surface of the transmission block 18 is slidably connected to the inclined surface of the side pressure block 19. The straight surface of the transmission block 18 is slidably connected to the limiting block 20. When the transmission block 18 is pulled down, it is restricted by the straight surface of the limiting block 20 and maintains a straight descent. Then, through the cooperation of the inclined surface of the transmission block 18 and the side pressure block 19, the descent of the transmission block 18 will push the inclined pressure block 19 towards the slider body 5. When the side pressure block 19 is pressed against one side of the slider body 5, the hydraulic oil is in a balanced state and can no longer be squeezed. At this time, the side pressure block 19 cooperates with the baffle on the other side to clamp and fix the slider body 5. The lower pressure plate 4 cooperates with the lifting platform 6 to press down and fix the slider body 5. The first spring 9 and the second spring 13 are used to release the downward pressure when the lower pressure plate 4 rises. The first spring 9 and the second spring 13 reset the lifting platform 6 and the transmission block 18.
