Abstract
The utility model belongs to oil hydraulic cylinder technical field, particularly relate to a kind of high strength cylinder body, it is characterized in that: described cylinder body is cylindrical tube, combined by inside and outside two cylindrical bodys, and make the endoporus of outer cylindrical body and the cylindrical of inner layer cylinder body be interference fit, and be provided with the tapped hole be connected with bottom and upper cover respectively in both ends of the surface.Its beneficial effect is: by the change to housing structure, makes to have stress between internal layer cylinder body and skin, and the generation of this preset stress counteracts the pressure of pressure oil effectively, drastically increases the intensity of cylinder body.Therefore, not only saved raw material, cost of production is reduced, and more compact structure, convenient installation.
Description
Technical field
The utility model belongs to oil hydraulic cylinder technical field, particularly relates to a kind of high strength cylinder body.
Background technique
Along with the development of productivity, the demand of people to high power hydraulic equipment also increases day by day, and oil hydraulic cylinder is as hydraulicdriven important power unit, and its output power will directly affect the performance of hydraulic equipment.Existing oil hydraulic cylinder usually by circle tube cylinder and be placed in the upper cover of both ends of the surface, bottom and be placed in the piston of inner chamber, piston rod forms, and makes piston rod movement by pressure oil in the change of cylinder body and piston space volume.From Pascal's law, when using identical lifting surface area piston, the pressure increasing pressure oil is only had to obtain larger output power.Thus, cylinder strength is increased most important to lifting hydraulic cylinder performance.And conventional method is generally by using the wall thickness of high performance material or increase oil cylinder to reach order, but these two kinds of methods not only make product weight increase raising cost of production, and the build increased also has impact to installation.
Summary of the invention
The utility model provides a kind of high strength cylinder body.
Scheme of the present utility model is achieved in that a kind of high strength cylinder body, it is characterized in that: described cylinder body is cylindrical tube, combined by inside and outside two cylindrical bodys, and make the endoporus of outer cylindrical body and the simplified cylindrical of internal layer circle be interference fit, and be provided with the tapped hole be connected with bottom and upper cover respectively in both ends of the surface.
The beneficial effects of the utility model are: by the change to housing structure, make to have stress between internal layer cylinder body and skin, and the generation of this preset stress counteracts the pressure of pressure oil effectively, drastically increases the intensity of cylinder body.Therefore, not only saved raw material, cost of production is reduced, and more compact structure, convenient installation.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model.
Fig. 2 is the plan view of Fig. 1.
In figure: 1, exterior cylinder, 2, inner cylinder body, 3, tapped hole is installed.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is further described:
As shown in Figure 1 and Figure 2, a kind of high strength cylinder body described in the utility model is cylindrical tube, combined by exterior cylinder 1 and inner cylinder body 2, and make the endoporus of exterior cylinder 1 and the cylindrical of inner cylinder body 2 be interference fit, and be provided with the installation tapped hole 3 be connected with bottom and upper cover respectively in exterior cylinder 1 and the both ends of the surface of inner cylinder body 2.By such scheme, make to have stress between internal layer cylinder body and outer cylinder block, the generation of this preset stress counteracts the pressure of pressure oil effectively, drastically increases the intensity of cylinder body.Not only save raw material, cost of production is reduced, and more compact structure, convenient installation.
