Description
Technical field
The utility model belongs to the vibration damper field, refers to especially a kind of adjustable hydraulic buffer.
Background technique
Hydraulic buffer is a kind of impact kinetic energy to be converted into hydraulic oil heat energy, realizes the linear a kind of hydraulic pressure installation that slows down and finally steadily stop of object.
In the decompression field, spring, rubber, cylinder buffering the movable object stroke initial stage with minimum linear continuing, along with increasing its reaction force, stroke also strengthens gradually, when stroke approaches end, reaction force also reaches the peak, be temporarily stored because the moving object energy can't be absorbed, moving object finally produces greatly bounce-back inevitably, causes mechanical failure.The existing damper that uses is as damping device, but damper is in the defective of oilhole system aspects, can moving object moment be stopped with the peak reaction force at the damping stroke initial stage, causes great mechanical shock, and then damper slowly slides into end of travel again.
The buffer that now uses can only absorb fixing energy, when energy to be absorbed changes, the corresponding buffer of essential replacing, and some equipment is to produce different impact forces according to the different product of processing, this fixed buffer can't adaptation equipment the variation of processing strength and the variation of the impact force that causes.
The model utility content
The purpose of this utility model is by the improvement to existing hydraulic buffer structure, and the realization buffer can be adjusted to the most appropriate snubber ability.
A kind of adjustable hydraulic buffer comprises housing, bonnet, and oil sealing, interior cylinder pressure body, piston, piston rod, impact head, bearing, spring, pressure accumulater, flow adjust bolt and flow is adjusted knob; Piston rod is packed in the housing, and with oil sealing sealing, the pressure accumulater of packing into successively, then the interior cylinder pressure body of in housing, packing into, the spring of packing in the interior cylinder pressure body, then with bonnet with housings close, there is a check valve at described bonnet place, and the flow of packing on the bonnet adjusts bolt and flow is adjusted knob; Also be provided with regulator on the described housing, described regulator is arranged at the shell end that the first side of bump is installed, and is porose in the middle of the described regulator, and piston rod passes the hole in the middle of the regulator; Piston rod between described impact head and housing is provided with Returnning spring.
Described flow is adjusted the groove structure of deepening gradually on the bolt, described groove is perpendicular to the axle center of adjusting bolt.
On the described regulator locking device is arranged.
The beneficial effects of the utility model are:
By the utility model, can be heat energy with the kinetic transformation of moving object, apparatus with shock absorbing by the use of pressure accumulater, has alleviated the maintenance amount, increases the service life.Simultaneously the technical program has realized that the snubber ability of hydraulic buffer can regulate according to requirements of one's work, has improved the usage space of buffer.

Embodiment
Describe concrete technological scheme of the present utility model in detail below in conjunction with accompanying drawing, specific embodiment of the utility model only is exemplary, can only be used for explaining the utility model and can not be interpreted as to be to restriction of the present utility model.
As shown in the figure, the utility model is achieved through the following technical solutions:
A kind of adjustable hydraulic buffer comprises housing 1, bonnet 14, and oil sealing 5, interior cylinder pressure body 17, piston 2, piston rod 6, impact head 7, bearing 4, spring 9, pressure accumulater 3, flow adjust bolt 12 and flow is adjusted knob 13; Piston rod 6 is packed in the housing 1, and with oil sealing 5 sealing, the pressure accumulater 3 of packing into successively, then the interior cylinder pressure body 17 of in housing 1, packing into, the spring 9 of packing in the interior cylinder pressure body 17, then with bonnet 14 housing 1 is sealed, there is a check valve 10 at described bonnet 14 places, and the flow of packing on the bonnet adjusts bolt 12 and flow is adjusted knob 13; Also be provided with regulator 15 on the described housing, described regulator 15 is arranged at the shell end that the first side of bump is installed, and is porose in the middle of the described regulator, and piston rod passes the hole in the middle of the regulator; Piston rod 6 between described impact head 7 and housing 1 is provided with Returnning spring 16.
Described pressure accumulater is the pressure accumulation sponge, certainly also can select the pressure accumulater of other kind in other embodiment of the present utility model, but that the pressure accumulation sponge has a cost is low, the advantages such as wide accommodation.
Described flow is adjusted the groove structure of deepening gradually on the bolt, described groove is perpendicular to the axle center of adjusting bolt.
Noise reduction cover 8 also is installed on the impact head 7 of described hydraulic buffer.
Regulator can be adjusted the snubber ability of buffer, changes according to the variation of the equipment that uses buffer, and will regulate locking with the stable absorption of assurance buffer by locking device.
Returnning spring can guarantee the Rapid reset of piston rod, is conducive to improve cushioning effect.
Be reacted to the process of compression piston by impact head when the bump of moving object, the motion of piston at first can so that check valve close, oil enters in the pressure accumulater because of the oilhole that is pressed through of piston, motion by oil will act on the power of bump head and subdue, after impacting releasing, spring resets piston rod, and check valve is opened simultaneously, and oil flows to rapidly in the interior cylinder pressure body.
The above only is the specific descriptions to technical solutions of the utility model, and those skilled in the art can improve according to the technical program certainly, and these improvement should be considered in the protection domain of the present utility model.
