Abstract
The utility model relates to a stroke adjustable hydraulic cylinder used for adjusting the stroke after long-time working of a plurality of equipments in all industries. The utility model consists of a cylinder bottom, a cylinder body, a cylinder head, a piston and a piston rod; the utility model is characterized in that the tail extended end of the piston rod is fixedly provided with a retaining block which is a round structure; the external round of the retaining block is provided with 12 equal graduations; meanwhile, the external end surface of the cylinder bottom is also provided with a 12 equal part dial. When the stroke of the piston is required to be adjusted, the retaining block is rotated according to the dial by corresponding angles before fixed by a locking bolt. The utility model has the advantages of reasonable design, simple structure, adjusting the speed and the stroke, safe operation, convenient application, economy and practicability, etc.
Description
Technical field
The utility model relates to plurality of devices a kind of stroke adjustable hydraulic cylinder that stroke need adjust after working long hours of every profession and trade.
Technical background
At present, domestic in industries such as heavy type, metallurgical machinery the application of oil hydraulic cylinder very extensive, no matter but be traversing cylinder, upset cylinder or flange type, solder type, pull rod type oil hydraulic cylinder or the like, their afterbody all is all-in-one-piece, the earrings formula or piston rod stretches out.They self all do not have adjustability when stroke need adjust after working long hours, and this will bring very big inconvenience to work.At existing problem in the existing technologies, the novel hydraulic cylinder of developing a kind of adjustable pressurized cylinder working stroke is very necessary.
Summary of the invention
In view of above-mentioned existing in prior technology problem, the purpose of this utility model is to avoid the shortcoming and defect part that exists in the above-mentioned technology, and provides a kind of reasonable in design, a kind of novel stroke adjustable hydraulic cylinder easy to adjust simple in structure.
A kind of stroke adjustable hydraulic cylinder described in the utility model; By cylinder bottom, cylinder body, cylinder head, piston, piston rod is formed; The afterbody external part that it is characterized in that piston rod is equipped with a block, and block is that round structure is drawn on its cylindrical 12 evenly divideds are arranged; Simultaneously also drawn 12 evenly divided dishes, when the stroke of piston rod need be adjusted, fixed by lock bolt after making block rotate corresponding angle by dial in the exterior edge face of cylinder bottom.
The afterbody external part of piston rod described in the utility model has screw thread and with the block scyewed joint, when the piston rod tailing screw flight is that M64x1.5 and stroke are need adjust 1.5mm the time, then block need rotate 360 ° of i.e. circles, when if constant its stroke of screw thread need be adjusted 0.125mm, then block need rotate 30 ° of i.e. equal portions, i.e. 360 ° 1/12 five equilibrium, computational methods are: 1.5: 0.125=360: X, wherein X is the angle that block need rotate.
Compared with prior art, the utility model is reasonable in design, and is simple in structure, can governing speed can adjust stroke again, also has handling safety, advantage such as easy to use, economical and practical simultaneously.
Description of drawings
The utility model has two accompanying drawings, wherein:
Fig. 1 is the plan view of stroke adjustable hydraulic cylinder.
Fig. 2 is the side view of stroke adjustable hydraulic cylinder.
Among the figure: 1, block, 2, cylinder bottom, 3, cylinder body, 4, cylinder head, 5, piston rod, 6, bleed valve, 7, modulating valve, 8, one-way valve, 9, bolt, 10, piston, 11, dial.
Embodiment
As shown in drawings, structure of the present utility model mainly partly is made up of block 1, cylinder bottom 2, cylinder body 3, cylinder head 4, piston 10, piston rod 5, bleed valve 6, modulating valve 7, one-way valve 8 and bolt 9 etc.Be screwed into a block 1 at piston rod tailing screw flight place, and on block 1 cylindrical, draw the scale that 12 equal portions are arranged, on cylinder bottom 2 end faces, also draw simultaneously the dial of 12 equal portions, when stroke need be adjusted, make block rotate corresponding angle like this by dial according to adjustment amount.Can realize the purpose of this utility model.
The utility model is after solution works long hours, because when the wearing and tearing of associated part or other reasons need be adjusted the oil cylinder piston stroke, can earlier lock bolt 9 be unclamped, concrete numerical value according to the stroke adjustment amount makes block 1 rotate corresponding angle according to dial, and then lock bolt 9 is tightened and can be realized.
For example: when the piston rod tailing screw flight is M64x1.5 and stroke need adjust 1.5mm the time, then block need rotate 360 ° of i.e. circles.When if constant its stroke of screw thread need be adjusted 0.125mm, then block need rotate 30 ° of i.e. equal portions (is example with 12 equal portions).
Computational methods are: 1.5: 0.125=360: X.
Work as X=30, the angle that the X----block need rotate, by that analogy.
