Abstract
The invention discloses a front guide mechanism of a hydraulic cylinder. The front guide mechanism of the hydraulic cylinder comprises a guide sleeve, a piston rod and a cylinder end, wherein the guide sleeve comprises a guide sleeve body and an extending section; the guide sleeve body is fixed to one end of the cylinder end through a connection assembly; the extending section is arranged inside the cylinder end; the piston rod penetrates in the guide sleeve; a sealing assembly is arranged between the outer section of the guide sleeve body and the piston rod; abrasion-resistant layers are arranged on the inner surfaces of the inner section of the guide sleeve body and the extending section in a surfacing mode. The structure of the front guide mechanism of the hydraulic cylinder is optimized by designing an existing guide sleeve and an existing end cover to be of an integrated structure, and therefore the assembly errors of the hydraulic cylinder are reduced, the structure is simplified, the accidents that the piston rod is pulled damaged or the like are avoided, the service life of the hydraulic cylinder is prolonged, and the production cost of the hydraulic cylinder is reduced.
Description
Technical field
The present invention relates to a kind of oil hydraulic cylinder, particularly relate to the preposition guide mechanism of a kind of oil hydraulic cylinder.
Background technique
At present, the preposition guide mechanism of existing oil hydraulic cylinder comprises end cap and guide sleeve mostly, needs end cap and guide sleeve two parts to assemble respectively during assembling, so inevitably there is assembly error, easily causes piston rod to pull.The cost of production of oil hydraulic cylinder is also higher simultaneously.
Summary of the invention
The object of the present invention is to provide the preposition guide mechanism of a kind of oil hydraulic cylinder, it has the advantages that assembly error is little and cost of production is low, to solve the problems referred to above that the preposition guide mechanism of oil hydraulic cylinder in prior art exists.
For reaching this object, the present invention by the following technical solutions:
The preposition guide mechanism of a kind of oil hydraulic cylinder, it comprises guide sleeve, piston rod and cylinder head, wherein, described guide sleeve comprises guide sleeve body and extension, described guide sleeve body is fixed on one end of described cylinder head by connection part, described extension is arranged in described cylinder head, and described piston rod penetrates in described guide sleeve, be provided with black box between the outer section of described guide sleeve body and described piston rod, and the inside surfacing of described guide sleeve body inner segment and extension there is wearing layer.
Especially, described connection part comprises the connecting through hole running through guide sleeve body and arrange, and corresponding connecting through hole offers tapped hole on described cylinder head, and connecting bolt lock onto in described tapped hole through described connecting through hole and is fixedly connected on cylinder head by guide sleeve.
Especially, described wearing layer is Cuprum alloy wearing layer.
Especially, described black box is combined by rectangular seal, v-ring, O-ring seals and y-shaped ring.
Especially, the outer surface of described extension O-ring seals together with being provided with at least between described cylinder head.
Beneficial effect of the present invention is, compared with prior art the preposition guide mechanism of described oil hydraulic cylinder carries out structure optimization, existing guide sleeve and end cover designs are structure as a whole, to reduce the assembly error of oil hydraulic cylinder, simplified structure, the accident such as avoid piston rod to pull, thus improve the working life of oil hydraulic cylinder, reduce the cost of production of oil hydraulic cylinder simultaneously.
