Description

A kind of location oil buffer
Technical field
The utility model belongs to the vibration damper field, refers to especially a kind of location oil 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.
At some mechanical field, the bump action has obvious difference with vibration damper, and Here it is also needs to control the stroke distances of buffering in the needs buffering.
The model utility content
The purpose of this utility model is by the improvement to existing hydraulic buffer structure, also can control the stroke distances of buffering when realizing buffering.
A kind of location oil buffer comprises housing, bonnet, protecgulum, oil sealing, interior cylinder pressure body, piston, piston rod, impact head, bearing, spring, pressure accumulater; Also include a location and stop nut and a location nut; Described housing outer wall is provided with screw thread, and the location stops nut and setscrew nut to be had internal thread and match with the housing outer wall; Interior cylinder pressure body is installed in the housing, and an end is fixed with housing with bonnet, is disposed with spring in interior cylinder pressure body, and the piston rod of piston is installed; Interior cylinder pressure is external to be provided with pressure accumulater and admittedly to seal with protecgulum, and protecgulum is provided with bearing with the housing contacting part, and the protecgulum outer installment has oil sealing; Locate to have a check valve in the middle of the cylinder pressure body in described bonnet is fixing.
It is tapped cylindrical shape that described location stops nut, and described location stops the internal diameter of nut greater than the diameter of impact head.
The beneficial effects of the utility model are:
By the utility model, can be heat energy with the kinetic transformation of moving object, stroke that also can controller buffer when realizing buffering, the working life that can improve 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 depicted in figs. 1 and 2, the utility model is achieved through the following technical solutions:
A kind of location oil buffer comprises housing 1, bonnet 12, protecgulum 11, oil sealing 5, interior cylinder pressure body 13, piston 2, piston rod 6, impact head 7, bearing 4, spring 9, pressure accumulater 3; Also include a location and stop nut 14 and a location nut 15; Described housing 1 outer wall is provided with screw thread, and the location stops nut 14 and setscrew nut 15 to be had internal thread and match with the housing outer wall; Interior cylinder pressure body 13 is installed in the housing 1, and an end is fixed with housing with bonnet 12, is disposed with spring 9 in interior cylinder pressure body 13, and the piston rod 6 of piston 2 is installed; Interior cylinder pressure body 13 is outside equipped with pressure accumulater 3 and admittedly seals with protecgulum 11, and protecgulum 11 is provided with bearing 4 with the housing contacting part, and protecgulum 11 outer installment have oil sealing 5; There is a check valve 10 at the place in the middle of the described bonnet 12 fixing interior cylinder pressure bodies.
In interior cylinder pressure body and interior cylinder pressure body be full of working oil between with housing.
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.
Noise reduction cover 8 also is installed on the impact head 7 of described hydraulic buffer.
It is tapped cylindrical shape that described location stops nut, and described location stops the internal diameter of nut greater than the diameter of impact head.
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.When bump object pushing piston bar compressed to buffer, after impact head entered the location and stops in the nut, piston rod was no longer mobile, can improve like this working life of buffer.
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.
