Abstract

The invention provides a piston rod type hydraulic cylinder structure. Two piston rods are of a split structure. The two ends of a piston are each connected with one piston rod. The piston rods and the piston are connected in a taper pin radial mode. The two piston rods are hollow. The ends, adjacent to the piston, of the piston rods are provided with radial holes for inflow and outflow of hydraulic oil. The two piston rods are of a cylindrical structure, the end, extending out of a cylinder barrel, of each piston rod is used for inflow and outflow of the hydraulic oil, and the end, for being connected with the piston, of each piston rod is connected with a plug. The end, connected with the piston, of each piston rod is provided with steps. The plugs are arranged on the top of the corresponding steps. An axial hole is formed in each plug and communicated with the radial hole in the corresponding piston rod. According to the piston rod type hydraulic cylinder structure, the two sides of the piston are each provided with one piston rod for transmitting power. According to the piston rod type hydraulic cylinder structure, the structure connecting mode is simple, displacement can be effectively transmitted, and overhauling is easy.

Description

technical field [0001] The invention relates to a piston rod type hydraulic cylinder structure, which belongs to the technical field of machinery. Background technique [0002] The piston rod type hydraulic cylinder is used to transmit the displacement. In order to ensure a certain displacement transmission accuracy, the existing hydraulic cylinder structure often makes the piston rod into an integrated structure, that is, the connection between the piston rod and the piston is a direct connection, so as to ensure that the hydraulic cylinder The transmission accuracy of the two-way displacement. This kind of structural form is single, and it is often impossible to complete the required tasks in practical applications. Contents of the invention [0003] The invention provides a piston rod type hydraulic cylinder structure, which can overcome the above-mentioned defects, and is different from the structure of the existing simple hydraulic cylinder. [0004] In order to sol...
