Utility model content
Purpose of the utility model is to solve above-mentioned the deficiencies in the prior art, provide a kind of anti-bias load thousand
Jin top hydraulic cylinder.
In order to reach above-mentioned purpose of utility model, the technical scheme that the utility model is provided is as follows: a kind of anti-bias load is very heavy
Top hydraulic cylinder, it includes hydraulic oil cylinder body, piston rod, concave spherical surface flange and gland, and the piston rod is set to hydraulic oil
In inner chamber of cylinder block, it is external which stretches out hydraulic cylinder, and piston rod top end is provided centrally with convex bulb, the gland
It is set on piston rod, the concave spherical surface flange center offers concave spherical surface, and the convex bulb is adapted with concave spherical surface, described recessed
Spherical flange is set to gland side, so that concave spherical surface flange and piston rod form overall structure, hydraulic oil cylinder body side
It is provided with the closed loop electrichydraulic control pipe-line system for controlling cavity pressure in hydraulic cylinder body, the hydraulic oil cylinder ends setting
There is the sealing element being in contact with piston rod, the sealing element is for guaranteeing that hydraulic cylinder intracoelomic cavity seals.
Preferably, the hydraulic oil cylinder body, piston rod, concave spherical surface flange and gland are stainless steel material system
At.
Preferably, the piston rod is an integral molding structure with convex bulb.
Based on the above-mentioned technical proposal, the utility model has following technological merit compared with prior art:
The utility model uses anti-bias load jack hydraulic oil cylinder, reasonable in design, enhances the ability of anti-bias load, has
Avoid to effect jack generation because stress does not damage jack due on center the case where.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1. hydraulic oil cylinder bodies, 2. piston rods, 3. concave spherical surface flanges, 4. glands, 5. convex bulbs, 6. recessed balls

Specific embodiment
Explanation that the utility model is further explained with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of anti-bias load jack hydraulic oil cylinder, it includes hydraulic oil cylinder body 1, piston rod 2, concave spherical surface method
Orchid 3 and gland 4, the piston rod 2 are set in 1 inner cavity of hydraulic oil cylinder body, which stretches out hydraulic oil cylinder body 1
Outside, and 2 top of piston rod is provided centrally with convex bulb 5, and the gland 4 is set on piston rod 2, in the concave spherical surface flange 3
The heart offers concave spherical surface 6, and the convex bulb 5 is adapted with concave spherical surface 6, and the concave spherical surface flange 3 is set to 4 side of gland, from
And concave spherical surface flange 3 and piston rod 2 form overall structure, 1 side of hydraulic oil cylinder body is provided with for controlling hydraulic cylinder
The closed loop electrichydraulic control pipe-line system 7 of 1 chamber pressure of body, 1 end of hydraulic oil cylinder body is provided with to be in contact with piston rod 2
Sealing element 8, the sealing element 8 is for guaranteeing 1 bore seal of hydraulic oil cylinder body.
The hydraulic oil cylinder body 1, piston rod 2, concave spherical surface flange 3 and gland 4 are that stainless steel material is made.The work
Stopper rod 2 is an integral molding structure with convex bulb 5.
When concave spherical surface flange 3 has unbalance loading, is adjusted with being adapted by convex bulb 5 with concave spherical surface 6, make piston rod 2 always
Center stressed reaches anti-bias load purpose.
Above content is the example and explanation of the utility model, but does not mean that the obtainable advantage of the utility model by this
Limitation may be realized in the simple transformation, and/or some embodiments to structure in all the utility model practice processes excellent
Wherein one or more of point are within the scope of protection of this application.
