A hydraulic cylinder piston block with an easy-to-assemble structure

Abstract

The invention relates to the field of engineering machinery, heavy machinery, transportation machinery and the like, and discloses a hydro-cylinder piston set block with a structure easy to mount and dismount. The hydro-cylinder piston set block comprises a first piston block, a second piston block, a third piston block and a fixing device, wherein the first piston block, the second piston block and the third piston block are sequentially installed on the left end plane of a hydro-cylinder piston rod. A first guiding ring is placed at the side end of the first piston block. Two lip-shaped sealing rings are placed at the side end of the second piston block, and an O-shaped ring is arranged on the other side of the second piston block. A second guiding ring is placed at the side end of the third piston block. The fixing device is installed on the piston rod, and is matched with the third piston block to be positioned. According to the hydro-cylinder piston set block with the structure easy to mount and dismount, a traditional structure of an original piston is broken, a split-type structure is adopted, so that when the surface of a piston or the sealing rings are damaged, the hydro-cylinder piston can be mounted, dismounted, checked, replaced and maintained fast, the maintaining time is shortened, operation is easy and reliable, and the hydro-cylinder piston set block is practical.

Description

Technical field [0001] The invention relates to the fields of engineering machinery, heavy machinery, transportation machinery and the like, and particularly relates to a hydraulic cylinder piston block with an easy-to-disassemble structure suitable for dismounting and disassembling a sealing ring with a small amount of expansion and contraction of a sealing material and a sealing ring with a slender hole . Background technique [0002] Hydraulic cylinder is an industrial automation device with a wide range of applications. There are many types and models, and the piston structure is also diverse. At present, the integrated piston is mainly used, and its assembly, disassembly, and maintenance are very difficult. With the advancement of industrial technology, hydraulic systems are widely used in engineering construction, mining and engineering machinery industries. In the application of some construction machinery and equipment, such as bulldozers, excavators, loaders, etc., due...
