Abstract
The utility model provides a hydro -cylinder buffer gear, relates to hydraulic cylinder and makes the field, set up on cylinder and piston rod in, the main part including the buffering sell, lock nut, the cylinder in be provided with a buffering hole, buffering round pin set up the end at the piston rod, buffering round pin fix on the piston rod through lock nut, the buffering hole on be provided with one and feed through the hydraulic fluid port outside the cylinder. The beneficial effects of the utility model are that: the utility model relates to a novelty, simple structure has possessed mechanical type buffer capacity, has protected the hydro -cylinder effectively, even there is slight difference in the buffering hole with the axiality that cushions the round pin, also can not be with cushioning the hole or cushioning the round pin and damage, even the buffering round pin damages also to be convenient for change, the piston rod still can repeat utilizing, simple manufacture, and convenient to use is convenient for change, and market value is high, the extend use of being convenient for.
Description
Technical field
The utility model relates to hydraulic jack and manufactures field, is specifically related to a kind of cylinder buffer mechanism.
Background technique
Along with the development of Chinese Industrialization process, the development of large-scale assembling manufacturing industry, oil cylinder is as the executive component of power, all play an important role in all trades and professions, its feature is exactly steady, the advantages such as High power output, oil cylinder kind general on market is a lot, but in engineering machinery, because working environment vibrations are larger, so just require the level and smooth damping mechanism of oil cylinder matching used with it, thus reduce engineering machinery when rugged environment work to the impact of oil cylinder, the buffering pattern of stoste cylinder pressure inside is fixed buffering, and it is comparatively complicated to add man-hour in design, namely piston rod and cushion pins are integral structures, as produced damage, piston rod and cushion pins must be scrapped simultaneously, be unfavorable for the recycling of part, cause very large waste.
Model utility content
It is simple, easy to use that technical problem to be solved in the utility model is to provide a kind of structure, is convenient to the cylinder buffer mechanism changing dismounting, possessed mechanical type shock-absorbing capacity.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of cylinder buffer mechanism, be arranged on cylinder barrel and piston rod, main body comprises cushion pins, locking nut, it is characterized in that: in described cylinder barrel, be provided with a cushion hole, described cushion pins is arranged on the termination of piston rod, described cushion pins is fixing on the piston rod by locking nut, described cushion hole is provided with one and is communicated in hydraulic fluid port outside cylinder barrel.
Described cushion pins is provided with a first quarter moon pad, described first quarter moon pad is fixed on cushion pins by O shape circle, is positioned at the outside of cushion pins simultaneously, limits cushion pins degrees of freedom.
Described locking nut and cushion pins are provided with gap, facilitate cushion pins can have slight swing in inside, when piston rod is under the propelling of rod chamber hydraulic coupling, when entering cylinder barrel cushion hole, cushion hole and cushion pins only have very little gap, cause fluid being subject to certain resistance from during hydraulic fluid port oil return, piston movement speed slows down, thus enhances buffering.
Described cushion pins axial plane has inclined-plane, is convenient to enter cushion hole easily, more accurate.
The beneficial effects of the utility model are: the utility model is novel in design, and structure is simple, has possessed mechanical type buffer capacity, has effectively protected oil cylinder, even if the coaxality of cushion hole and cushion pins has slight difference, also cushion hole or cushion pins can not be damaged; Also be convenient to change even if cushion pins damages, piston rod still can repeat in utilization, makes simple, easy to use, and be convenient to change, market value is high, is convenient to utilization and extention.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, a kind of cylinder buffer mechanism, be arranged on cylinder barrel 1 and piston rod 8, main body comprises cushion pins 2, locking nut 3, a cushion hole 4 is provided with in cylinder barrel 1, cushion pins 2 is arranged on the termination of piston rod 8, cushion pins 2 is fixed on piston rod 8 by locking nut 3, cushion hole 4 is provided with one and is communicated in hydraulic fluid port 5 outside cylinder barrel 1, after arranging like this, even if cushion hole 4 has slight difference with the coaxality of cushion pins 2, also cushion hole 4 or cushion pins 2 can not be damaged, also be convenient to change even if cushion pins 2 damages, piston rod 8 still can repeat in utilization, cushion pins 2 is provided with a first quarter moon pad 6, first quarter moon pad 6 is fixed on cushion pins 2 by O shape circle 7, be positioned at the outside of cushion pins 2 simultaneously, limit cushion pins 2DOF, locking nut 3 and cushion pins 2 are provided with gap, facilitate cushion pins 2 can have slight swing in inside, when piston rod 8 is under the propelling of rod chamber hydraulic coupling, when entering cylinder barrel 1 cushion hole 4, cushion hole 4 and cushion pins 2 only have very little gap, cause fluid being subject to certain resistance from during hydraulic fluid port 5 oil return, piston movement speed slows down, thus enhance buffering, cushion pins 2 axial plane has inclined-plane, be convenient to enter cushion hole 4 easily, more accurate.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
