The engine cylinder body pushes the placement plate 4 down, so that the first spring 8 is compressed. When the engine cylinder body is completely placed on each placement plate 4, the staff starts the motor 2, and the threaded rod 13 rotates, thereby driving the two clamping plates 12 to approach each other until the limit plate 9 is clamped. At this time, the placement plate 4 is fixed, which can prevent the placement plate 4 from shaking up and down when clamped. At this time, it can be ensured that when engine cylinders of different sizes and shapes are placed, their top and bottom surfaces remain perpendicular to the top surface of the base 1. When clamping, the staff starts the electromagnet 19, and the iron pressure plate 21 is attracted to enter the limit groove 18, and the second spring 20 is compressed. Then the staff pushes the three movable plates 14 according to the position and size of the engine cylinder until the three movable plates 14 are pushed to the appropriate position, and then the electromagnet 19 is turned off. The pressure plate 21 contacts the fixed rod 16 under the elastic force of the second spring 20, and the movable plate 14 is fixed. In this way, the position of the clamping device can be adjusted according to the engine cylinders of different sizes and shapes. Finally, the staff starts the hydraulic cylinder 15, the push plate 22 descends and contacts the engine cylinder, and then starts the electric telescopic rod 24, and the push plate 25 moves until it contacts both sides of the engine cylinder, so that the clamping of the engine cylinder can be completed.
