Problems solved by technology
[0003] At present, an interference fit is used between the piston rod installation section of the traditional hydraulic cylinder and the rear end cover to prevent displacement and rotation between the two. However, in the actual processing process, due to improper tolerance control or long-term use of the mechanism Due to wear and other reasons, there will still be relative rotation between the two, and the rotation phenomenon will easily cause damage to the stroke indicating device and the oil inlet pipe, affecting the normal operation of the mechanism.

The invention discloses a mounting structure for a piston rod and a rear end cover of a hydraulic cylinder. The mounting structure comprises a cylinder base, the rear end cover and the hydraulic cylinder, wherein the rear end cover is arranged at one end of the cylinder base; a mounting hole for mounting the piston rod is arranged on the rear end cover; an anti-rotating structure in a key-slot matching form is arranged between the mounting hole and a mounting section of the piston rod; a key is arranged on the mounting section of the piston rod; and a slot is correspondingly arranged in the mounting hole. A key-slot anti-rotating structure is added between the mounting section of the piston rod and the mounting hole of the rear end cover in the mounting structure for the piston rod and the rear end cover of the hydraulic cylinder, so that the structure is simple and is easy to realize, the relative rotating phenomenon between the piston rod and the rear end cover is eliminated and the running of the whole mechanism is safe and reliable.
Description
technical field [0001] The invention relates to a hydraulic oil cylinder, in particular to an installation structure of a piston rod and a rear end cover of the hydraulic oil cylinder. Background technique [0002] Hydraulic cylinders are the main components of construction machinery, equipped with special tools for lifting, bending, straightening, extrusion, shearing, riveting, jacking, stretching, disassembly, punching, extrusion of construction steel bars, bridges, Construction machinery and other operations. [0003] At present, an interference fit is used between the piston rod installation section of the traditional hydraulic cylinder and the rear end cover to prevent displacement and rotation between the two. However, in the actual processing process, due to improper tolerance control or long-term use of the mechanism Reasons such as wearing and tearing cause still can produce relative rotation phenomenon between the two, and rotation phenomenon very easily causes th...
