Description
Technical field
The utility model relates to a kind of oil cylinder piston dismantling device.
Background technology
Engineering machinery is the important component part of Chinese equipment manufacturing industry.Put it briefly, the necessary mechanized equipment of comprehensive mechanized construction engineering needed for all restoration in earth-rock construction engineerings, pavement construction and maintenance, the operation of flow-type lift and various architectural engineering, is called engineering machinery.It is mainly used in national defense construction engineering, communications and transportation construction, energy industry construction and the field such as the raw and semifinished materials industries construction such as production, mine and production, agriculture, forestry, water conservancy construction, industry and civil buildings, urban construction, environmental protection.
Oil cylinder converts the pressure of liquid to mechanical energy and the device exported, and plays an important role in engineering machinery.And the oil sealing in oil cylinder belong to consumable accessory often need change, need when changing it first to dismantle piston.Traditional piston method for dismounting needs to look for two corresponding to two installing holes on piston to alter bar, and during operation, two are altered two installing holes that piston is inserted in bar front end, operating personnel hold and alter bar, and another operating personnel turn on piston with crowbar operation.What this method needed two corresponding rugosity alters bar, now looks for comparatively difficulty; Security is poor, efficiency is low, and easily makes to alter bar contact position Remedy for Piston Damage.
Summary of the invention
The technical problems to be solved in the utility model be to provide a kind of easy and simple to handle, safety, efficiency are high, and the oil cylinder piston dismantling device of not fragile piston.
For solving the problems of the technologies described above, oil cylinder piston dismantling device of the present utility model adopts following two technical schemes:
Technical scheme one:
Oil cylinder piston dismantling device of the present utility model comprises body, is arranged on two bearing pins of body side, moment of torsion input block; The size of described two bearing pins is corresponding with two installing holes on piston; Moment of torsion input block is fixed on the opposite side of body.
Described moment of torsion input block is fixed on the pivot place of body opposite side, for having four prism type or the hexagon on two surfaces that are parallel to each other.During operation, only need to use outer corner spanner, outer hexagonal spanner or monkey wrench namely to rotate body by moment of torsion input block, then drive piston to rotate by two bearing pins, thus piston is pulled down.
Described moment of torsion input block, with through hole, is fixed on the pivot place of body opposite side.During operation, a stock is inserted this through hole, then rotate stock and body can be driven to rotate, and piston is pulled down.
Described moment of torsion input block is made up of orthogonal two sections of poles, and the pivot place of one section strut ends and body opposite side is welded and fixed.
Described moment of torsion input block is the fixed leg being fixed on body opposite side pivot both sides.During operation, a stock is passed in the middle of two fixed legs, then rotate stock and body can be driven to rotate, and piston is pulled down.
Described body is processed with two elongate holes, two bearing pins are each passed through corresponding elongate holes and the screw thread processed by its one end and locking nut are installed fixing.During operation, can locking nut be unclamped, adjust distance between two bearing pins according to the distance on piston between two installing holes and then bearing pin is fixed by locking nut.
Technical scheme two:
Oil cylinder piston dismantling device of the present utility model comprises body and is arranged on two bearing pins of body side; The pivot place of body is processed with the four prism type or hexagon through hole with two surfaces that are parallel to each other.
Beneficial effect:
The utility model structure is simple, easy to use, handling safety, operating efficiency are high, can not damage piston in operation.
