The motor 146 provides power, which is transmitted through the reducer 145, bevel gear 247, bevel gear 144 and lead screw 43. The driving clamping blocks 51 move closer to each other to clamp the oil cylinder. The soft pad 52 allows multiple sizes of oil cylinders to be clamped at the same time. After the upper clamping block 51 clamps the oil cylinder, the oil cylinder is raised and the oil cylinder sliding assembly is placed on the top of the lower bracket 6 41. Then the oil cylinder sliding assembly is clamped and the oil cylinder is lowered.

Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0038] The main functions achieved by this utility model are: by setting up clamping device 2 05, multiple sizes of hydraulic cylinders can be clamped simultaneously, improving the ease of use of the machine; and by setting up pressing device 03 and clamping device 1 04, the hydraulic cylinders are automatically centered and clamped, improving assembly accuracy. This solves the existing technical problems that require changing clamps when clamping hydraulic cylinders of different sizes, resulting in poor machine ease of use and requiring workers to manually fix and clamp the hydraulic cylinders, leading to low assembly accuracy.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
