Abstract
The utility model relates to a hydraulic cylinder which comprises a piston cylinder body, a piston and a piston rod, wherein one end of the piston rod is fixedly connected with the piston; and the other end of the piston rod is fixed on a rigid bracket. The hydraulic cylinder is characterized in that the piston rod and the piston adopt an integrated structure; and the external surface of the piston is wrapped by a copper sheet. The hydraulic cylinder has the advantages the structure is simple, the service life is long, and the safety is high.
Description
Technical field
The utility model relates to a kind of oil hydraulic cylinder, specifically, relates to a kind of piston hydraulic cylinder.
Background technique
The piston of existing piston oil hydraulic cylinder and piston rod are that split processes mostly, be fixed together by fixed block during installation, like this, piston and piston rod are difficult to guarantee concentricity when mounted, easily cause piston rod in guiding piston motion process, deviation to take place, cause the oil hydraulic cylinder locking; The piston that also has the existing piston oil hydraulic cylinder is easy to wear during to-and-fro motion in piston/cylinder, causes hydraulic pressure not enough, influences the proper functioning of oil hydraulic cylinder.Therefore, need a kind of new technological scheme to solve above-mentioned technical problem.
The model utility content
The purpose of this utility model provides a kind of simple in structure, long service life.The oil hydraulic cylinder that maneuverability is strong.
The technical solution adopted in the utility model is:
A kind of oil hydraulic cylinder, comprise piston/cylinder, piston and piston rod, an end of described piston rod is fixedlyed connected with piston, and the other end of described piston rod is fixed on the rigid support, described piston rod and piston are integral structure, are enclosed with one deck copper sheet on the outer surface of described piston.
The thickness of described copper sheet is 0.02-0.08mm.
Piston rod of the present utility model and piston are integral structure, i.e. the disposable machine shaping of piston rod and piston can guarantee the concentricity of piston rod and piston can make the motion of piston in piston/cylinder deviation can not take place, and prevents oil hydraulic cylinder generation locking phenomenon; The utility model has also wrapped up the wear-resisting copper sheet of one deck at the outer surface of piston, and when piston motion, piston contacts with piston/cylinder by this copper sheet, can alleviate the wearing for piston amount effectively, the working life of improving whole oil hydraulic cylinder.
The utility model has the advantages that: simple in structure, long service life, safe.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present utility model.
Wherein: 1, piston/cylinder, 2, piston, 3, piston rod, 4, rigid support, 5, copper sheet.
Embodiment
As shown in Figure 1: a kind of oil hydraulic cylinder, comprise piston/cylinder 1, piston 2 and piston rod 3, one end of piston rod 3 is fixedlyed connected with piston 2, the other end of piston rod 3 is fixed on the rigid support 4, piston rod 3 be an integral structure with piston 2, i.e. piston rod 3 and piston 2 disposable machine shapings can guarantee the concentricity of piston rod 3 and piston 2, can make the motion of piston 2 in piston/cylinder 1 deviation can not take place, prevent oil hydraulic cylinder generation locking phenomenon; On the outer surface of piston 2, be enclosed with one deck copper sheet 5, the thickness of this copper sheet 5 is 0.02-0.08mm, and when piston 2 motions, piston 2 contacts with piston/cylinder 1 by this copper sheet 5 like this, can alleviate the wear extent of piston 2 effectively, the working life of improving whole oil hydraulic cylinder.
