Abstract

The invention discloses a mechanism used for disassembling engineering hydraulic oil cylinder piston rod components. A clamp body component is divided into two parts which are respectively mounted on two clamp body supports and are capable of sliding on a clamp body slide rail base, the clamp body supports are respectively fixed to two T-shaped nuts, forward and reverse T-shaped screws penetrate the T-shaped nuts, forward and reverse screw threads on the forward and reverse T-shaped screws are respectively matched with internal threads of the T-shaped nuts, one ends of the forward and reverse T-shaped screws are connected with a clamp power system through keys, the clamp power system drives the forward and reverse T-shaped screws to rotate through the keys, a clamp body is a cuboid provided with a groove, a spring is arranged in the groove, one end of the spring is fixed in the groove through a stopper screw while the other end is connected with a square cotter provided with a protrusion portion, a lifting hook is arranged on the clamp body, and one end of the lifting hook is rotatably fixed on the clamp body. The mechanism has the advantages that the engineering hydraulic oil cylinder piston rod components can be conveniently and rapidly disassembled without damaging other parts.

Description

technical field

[0001] The invention belongs to the technical field of mechanical remanufacturing, and relates to a mechanism for disassembling a piston rod assembly of an engineering hydraulic oil cylinder. Background technique

[0002] In order to solve the problem of resource shortage, the country actively accelerates the development of circular economy. Remanufacturing engineering is an important measure and advanced form to implement the national "circular economy" outline. A wide variety of hydraulic cylinders with precise structures are important functional components and key parts of construction machinery with a huge inventory. Remanufacturing failed hydraulic cylinders will obtain huge economic and social benefits. Engineering hydraulic cylinders are composed of cylinder head, cylinder barrel assembly, piston rod assembly, seals and other parts. Common hydraulic cylinder repair problems include seal damage, piston rod assembly deformation, buffer sleeve wear and s...
