[0002] Hydraulic cylinders are key actuators in hydraulic systems, responsible for converting hydraulic energy into mechanical energy to achieve linear or rotational motion. Drilling is an essential step in the production and maintenance of hydraulic cylinders, primarily used to install various cylinder components such as the piston rod, cylinder head, and seals. During this process, precise positioning, size, and shape of the holes in the hydraulic cylinder must be ensured to ensure proper installation and sealing of the cylinder assembly.

[0003] In the existing technology, when drilling a hole in a hydraulic cylinder, the hydraulic cylinder needs to be stably supported to prevent the hydraulic cylinder from sliding during the drilling process. When positioning and supporting a hydraulic cylinder with a larger inner diameter, the inner wall of the hydraulic cylinder can be supported, and when positioning and supporting a hydraulic cylinder with a smaller inner diameter, the outer wall of the hydraulic cylinder can be supported.
