Abstract
The utility model discloses a stroke-adjustable hydraulic oil cylinder which comprises a cylinder body, a piston, a piston rod, a cylinder head and a cylinder tail. The piston and the piston rod are arranged in the cylinder body, the piston is fixedly connected with the piston rod, the cylinder head and the cylinder tail are respectively fixed at two ends of the cylinder body, an adjusting bolt is arranged at the cylinder tail, the adjusting bolt is connected with the piston, and buffer devices are respectively fixed on the cylinder head and the cylinder tail. Each buffer device comprises a buffer plate and an elastic part fixedly connected with the buffer plate, the elastic part is respectively and fixedly connected with the cylinder head and the cylinder tail, and the buffer plate is arranged corresponding to the piston. Due to the face that the adjusting bolt is connected on the piston, the stroke-adjustable hydraulic oil cylinder can conveniently adjust the stroke length of the piston so as to be convenient to adjust, good in flexibility and wide in function. Simultaneously, the buffer devices corresponding to the piston are arranged on the cylinder head and the cylinder tail so as to prevent the piston from colliding with the cylinder head or the cylinder tail in a running process and greatly prolong service life of the hydraulic oil cylinder.
Description
Technical field
The utility model relates to the hydraulic jack field, particularly relates to a kind of range-adjustable hydraulic jack.
Background technique
Hydraulic jack with hydraulic pressure can change mechanical energy into, the do straight reciprocating motion hydraulic actuator of (or oscillating motion).When realizing to-and-fro motion with it, can remove speed reducer from, and not have drive gap, therefore motion steadily is used widely in the hydraulic system of various machineries.
Yet the stroke that existing hydraulic jack generally can not regulating piston, validity is lower, and flexibility is relatively poor, and easily terminal and cylinder head or cylinder tail clash in the stroke of piston in cylinder body, have reduced the working life of hydraulic jack widely.
The model utility content
The technical problem that the utility model mainly solves provides that a kind of validity is high, flexibility is good, the range-adjustable hydraulic jack of good buffer effect, long service life.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of range-adjustable hydraulic jack is provided, comprises cylinder body, piston, piston rod, cylinder head and cylinder tail; Said piston, piston rod are arranged in the cylinder body, and piston is fixedly connected with piston rod, and said cylinder head, cylinder tail are separately fixed at the cylinder body two ends; Said cylinder tail is provided with the adjusting bolt; Said adjusting bolt is connected with piston, and said cylinder head, cylinder tail are fixed with damping device respectively, and said damping device comprises cushion plate and the elastic component that is fixedly connected with cushion plate; Said elastic component is fixedly connected with cylinder head, cylinder tail respectively, the corresponding setting with piston of said cushion plate.
In preferred embodiment of the utility model, be provided with seal ring between said adjusting bolt and the cylinder tail.
In preferred embodiment of the utility model, said cushion plate is wooden cushion plate.
In preferred embodiment of the utility model, said elastic component is a spring, and said spring evenly is fixed on the cushion plate ringwise.
In preferred embodiment of the utility model, said cylinder head, cylinder tail are connected with cylinder body through fixed plate respectively.
The beneficial effect of the utility model is: the utility model range-adjustable hydraulic jack is owing to be connected with the adjusting bolt on piston, the stroke length of regulating piston easily, thus make this hydraulic jack can apply different active forces; Easy to adjust, validity is high, and flexibility is good; Function is wider; Simultaneously, owing to be provided with and piston corresponding buffered device, can prevent that piston from bumping with cylinder head or cylinder tail in running at cylinder head, cylinder tail; Avoid breaking down, improved the working life of hydraulic jack widely.
Description of drawings
Fig. 1 is the perspective view of the utility model range-adjustable hydraulic jack one preferred embodiment;
The mark of each parts is following in the accompanying drawing: 1, cylinder body, 2, cylinder head, 3, the cylinder tail, 4, piston, 5, piston rod, 6, regulate bolt, 7, cushion plate, 8, elastic component, 9, fixed plate.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the utility model is embodiment comprise:
A kind of range-adjustable hydraulic jack comprises cylinder body 1, piston 4, piston rod 5, cylinder head 2 and cylinder tail 3, and said piston 4, piston rod 5 are arranged in the cylinder body 1; Piston 4 is fixedly connected with piston rod 5; Said cylinder head 2, cylinder tail 3 are separately fixed at cylinder body 1 two ends, and said cylinder tail 3 is provided with regulates bolt 6, and said adjusting bolt 6 is connected with piston 4; Said cylinder head 2, cylinder tail 3 are fixed with damping device respectively; Said damping device comprises cushion plate 7 and the elastic component 8 that is fixedly connected with cushion plate 7, and said elastic component 8 is fixedly connected with cylinder head 2, cylinder tail 3 respectively, said cushion plate 7 and piston 4 corresponding settings.
Be provided with seal ring between said adjusting bolt 6 and the cylinder tail 3, can play good sealing effect.
Said cushion plate 7 is wooden cushion plate, makes simply, and it is convenient to change, and cost is lower.
Said elastic component 8 is a spring, and said spring evenly is fixed on the cushion plate 7 ringwise, can play good cushioning effect to piston 4.
Said cylinder head 2, cylinder tail 3 are connected with cylinder body 1 through fixed plate 9 respectively, and easy installation and removal is convenient to keep in repair.
Add man-hour; Come the stroke of regulating piston 4 through rotation adjusting bolt 6, it is reciprocating that piston 4 drives piston rods 5, when piston 4 moves to termination or end tail; Damping device cushions piston 4, prevents that piston 4 and cylinder head 2 or cylinder tail 3 from bumping and damage hydraulic jack.
Compared with prior art, the utility model range-adjustable hydraulic jack is owing to be connected with adjusting bolt 6, the stroke length of regulating piston 4 easily on piston 4; Thereby make this hydraulic jack can apply different active forces, easy to adjust, validity is high; Flexibility is good, and function is wider, simultaneously; Owing to be provided with and piston 4 corresponding buffered devices at cylinder head 2, cylinder tail 3; Can prevent that piston 4 from bumping with cylinder head 2 or cylinder tail 3 in running, avoid breaking down, improve the working life of hydraulic jack widely.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
