Abstract
The utility model relates to a composite hydraulic cylinder which comprises a piston cylinder body, a piston, a piston rod and a plunger type cylinder body. One end of the piston rod is fixedly connected with the piston; the other end of the piston rod is fixed on a rigid support; the plunger type cylinder body is arranged outside the piston cylinder body; the plunger type cylinder body is a rigid barrel; and a flange interface is arranged at one end of the plunger type cylinder body. The composite hydraulic cylinder is characterized in that the flange interface and the plunger type cylinder body form an integral structure; a guide sleeve is arranged in a position where the piston cylinder body is in contact with the piston rod; and the guide sleeve is fixed on the piston cylinder body. The composite hydraulic cylinder has the advantages of simplicity in manufacture, low cost and long service life.
Description
Technical field
The utility model relates to a kind of oil hydraulic cylinder, specifically, relates to a kind of composite hydraulic cylinder.
Background technique
The flange-interface of one end setting of the plunger cylinder of existing composite hydraulic cylinder is fixed on the plunger cylinder by fixed block mostly, and sealing gasket need be set between farad interface and plunger cylinder, so just increase cost and time when installing, influenced working efficiency.Also having the piston rod of existing composite hydraulic cylinder is directly to contact with piston/cylinder, and piston/cylinder is easy to wear scraps waste material.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 composite hydraulic cylinder simple, with low cost, long service life of making.
The technical solution adopted in the utility model is:
A kind of composite hydraulic cylinder, comprise piston/cylinder, piston, piston rod and plunger cylinder, one end of described piston rod is fixedlyed connected with piston, the other end of described piston rod is fixed on the rigid support, and described plunger cylinder places outside the piston/cylinder, and described plunger cylinder is a rigid cylinder, one end of described plunger cylinder is provided with flange-interface, described flange-interface and plunger cylinder are integral structure, and the contacting point of described piston/cylinder and piston rod is provided with guide sleeve, and this guide sleeve is fixed on the piston/cylinder.
Flange-interface of the present utility model and plunger cylinder are integral structure, and casting processing moulding has together strengthened the sealing of plunger cylinder; The utility model is provided with guide sleeve in the contacting point of piston/cylinder and piston rod, and this guide sleeve is fixed on the piston/cylinder, and piston rod just directly contacts with guide sleeve like this, has avoided the wearing and tearing of piston/cylinder, has improved the working life of piston/cylinder.
The utility model has the advantages that: make simple, with low cost, long service life.
