Description
Technical field
The utility model relates to hydraulic system technical field, particularly relates to a kind of hydraulic jack of rolling machine.
Background technique
The cylinder barrel of traditional hydraulic jack is generally to be connected with cylinder bottom by screw thread and to locate, and then to be connected by welding bead and to seal, this structure can be suitable in miniature bore cylinder, but it is just more difficult in the design of large-diameter oil cylinder, large-sized usual processing cost that is threaded is higher, precision comparison is difficult to ensure, during cooperation, contact length is longer, so often occur that screw-thread fit is undesirable in assembling, assembling difficulty is higher, be difficult to screw the phenomenons such as specified position, axial float causes seal ring to damage or premature breakdown continually, finally do not reach sealing effect, cause gas leakage leakage of oil.
Summary of the invention
The purpose of this utility model is intended to solve the deficiencies in the prior art, and provides a kind of hydraulic jack of rolling machine.
The utility model for achieving the above object, by the following technical solutions: a kind of hydraulic jack of rolling machine, comprise cylinder barrel, cylinder cap, cylinder bottom, piston rod, oil inlet pipe, oil outlet tube, described cylinder cap and described cylinder bottom are separately positioned on described cylinder barrel two ends, described piston rod is plugged in described cylinder cap, described oil inlet pipe is connected with the head of described cylinder barrel, described oil outlet tube is connected with described cylinder bottom, it is characterized in that, described cylinder barrel and described cylinder cap joint are provided with adpting flange, are connected by described cylinder cap by bolt with described cylinder barrel.
Described adpting flange is fixed by welding on described cylinder barrel.
The beneficial effects of the utility model are: the utility model assembling is simple and convenient, is applicable to the oil cylinder of size cylinder diameter, can not causes gas leakage leakage of oil.
