Problems solved by technology
[0002] At present, the general hydraulic compression of the installation base is realized by driving the compression block with an ordinary oil cylinder installed outside the base. It is often necessary to set up a special guide device. The hydraulic pressing mechanism is complex and takes up a lot of space. It is not suitable for many occasions with limited space.

Embodiment Construction
[0010] Such as figure 1 As shown, the main components of the short stroke long piston rod cylinder compression method include cylinder bottom flange 1, cylinder body 2, piston rod 3, piston rod cylinder head guide 4, piston rod front guide 5, gasket 6, pressure Tight block 7 and nut 8.
[0011] Oil cylinder body 2 is very short, and piston stroke has only less than 100 millimeters, and oil cylinder piston rod 3 is very long, and its length is tens of times of oil cylinder stroke. Cylinder bottom flange 1 and cylinder body 2 are mounted on the rear end face of the beam together by screws, and cylinder piston rod 3 can protrude from the front end face of the beam, and its front end is designed with steps and threads. The gasket 6, the compression block 7 and the nut 8 are set on the front end of the piston rod 3 in turn, the gasket 6 leans against the step of the piston rod 3, the nut 8 will press the compression block 7 against the gasket 6, and the compression block 7. A wed...

The invention relates to a method for pressing an oil cylinder with a short stroke and a long piston rod. The cylinder body of the oil cylinder is very short, the piston stroke is smaller than or equal to one hundred millimeters, the piston rod of the oil cylinder is very long, and the length of the piston rod is tens of times the stroke of the oil cylinder. The cylinder body is installed on the rear end face of a beam through screws, the piston rod can extend out of the front end face of the beam, and the front end of the piston rod is provided with a step and threads. The front end of the piston rod is sleeved with a gasket, a pressing block and nuts in sequence, the gasket abuts against the step of the piston rod, the pressing block tightly abuts against the gasket through the nuts, and the front-and-rear position of the pressing block at the front end of the piston rod can be adjusted by adjusting the thickness of the gasket. The piston rod is provided with a guide in the cylinder body, and besides a front guide which is installed in the front panel of the beam is arranged at the front end of the piston rod. When a piston retracts, the piston rod drives the pressing block to tightly press a mounting base, and when the piston of the oil cylinder extends out, the pressing effect of the pressing block on the mounting base disappears, so that the mounting base is easily disassembled and removed. According to the method for pressing the oil cylinder with the short stroke and the long piston rod, the mounting base can be quickly and hydraulically pressed through a simple compact short-stroke and long-piston-rod oil cylinder pressing structure.
Description
technical field [0001] The invention relates to a method for pressing an oil cylinder for installing a base, in particular to a method for pressing an oil cylinder with a short stroke and a long piston rod. Background technique [0002] At present, the general hydraulic compression of the installation base is realized by driving the compression block with an ordinary oil cylinder installed outside the base. It is often necessary to set up a special guide device, and the hydraulic pressing mechanism is complex and takes up a lot of space, which is not suitable for many occasions with limited space. Contents of the invention [0003] The object of the present invention is to provide a short-stroke long-piston-rod oil-cylinder pressing method in order to solve the problem of realizing the hydraulic pressing of the installation base through a simple and compact structure in a limited space. [0004] The technical solution adopted in the present invention is: a short-stroke lo...
