Description
[technical field]
The utility model relates to a kind of cushioning device for oil cylinder, particularly relates to a kind of cushioning device for oil cylinder for fork truck or forklift.
[background technique]
The oil cylinder of fork truck or forklift is one of main function components of cargo lifting, because the devices such as door frame, pallet fork, goods shelf and piston rod have certain weight, to attract deposit again when oil cylinder is descending very large kinetic energy, at their stroke terminal, mechanical collision can be caused at the bottom of bar head and oil cylinder, produce larger impact force to such an extent as to produce and vibrate and send impact noise, in order to avoid this mechanical collision, generally adopt damping device.But in existing damping device, structure simply then cushioning effect is bad, there is the then structure of certain effect more complicated.
Given this, the necessary cushioning device for oil cylinder providing a kind of improvement, to overcome the defect that prior art exists.
[summary of the invention]
The purpose of this utility model is that a kind of structure is simple, stable working, shock-free cushioning device for oil cylinder in order to provide.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme: a kind of cushioning device for oil cylinder, comprise throttle shaft, pole socket and guideway, the side that described pole socket comprises bottom surface and extends from bottom surface, bottom surface and side surround assembly hole, side surrounds the opening communicated with assembly hole, described guideway is provided with the containing space run through, the side plate that described throttle shaft is provided with base plate and extends from base plate, base plate and side plate surround accepting hole, side plate surrounds the window communicated with accepting hole, described guideway is installed in the assembly hole of pole socket, the side plate of described throttle shaft is provided with some holes of arranging up and down away from the position of window, described hole communicates with described accepting hole, fluid is assembled with in described assembly hole and described accepting hole, described throttle shaft is assembled in the containing space of guideway and also can relatively moves up and down by guideway, in the process, some holes on the side plate of throttle shaft are successively directed to axle sleeve and close, fluid in the accepting hole of throttle shaft is squeezed throttle shaft by from described hole.
The utility model defines further, and described throttle shaft, pole socket are overlapping with the center line of guideway.
The utility model defines further, and described cushioning device for oil cylinder also comprises the hole shelves for fixed guide axle sleeve and pole socket.
The utility model defines further, and described cushioning device for oil cylinder also comprises the spring be fixed on the bottom surface of pole socket, and described spring is connected on the base plate of described throttle shaft, and the center line of described spring is overlapping with the center line of the assembly hole of described pole socket.
The utility model defines further, and described cushioning device for oil cylinder also comprises the axle shelves be assembled in throttle shaft, and when the relative guideway of throttle shaft moves downward certain position, axle shelves are kept out on guideway, restriction throttle shaft continue move downward.
The utility model defines further, and described accepting hole, described containing space are overlapping with the center line of described assembly hole.
Compared with correlation technique, the throttle shaft of the utility model cushioning device for oil cylinder arranging some holes, adopt porous variable flow resistance technology, pole socket being slowed down mild without impacting.
[accompanying drawing explanation]
Fig. 1 is the schematic diagram that the utility model cushioning device for oil cylinder is positioned at primary importance; And
Fig. 2 is the schematic diagram that the utility model cushioning device for oil cylinder moves to the second place.
[embodiment]
Refer to shown in Fig. 1 to Fig. 2, the utility model cushioning device for oil cylinder comprises spring 1, throttle shaft 2, axle shelves 3, pole socket 4, guideway 5, hole shelves 6.Described throttle shaft 2, pole socket 4 are overlapping with the center line of guideway 5.
The side 42 that described pole socket 4 comprises bottom surface 41 and extends from bottom surface 41.Bottom surface 41 and side 42 surround assembly hole 43, and side 42 surrounds the opening (sign) communicated with assembly hole 43.Described guideway 5 is provided with the containing space (sign) run through.The side plate 22 that described throttle shaft 2 is provided with base plate 21 and extends from base plate 21.Base plate 21 and side plate 22 surround accepting hole 23, and side plate 22 surrounds the window 24 communicated with accepting hole 23.Described guideway 5 to be installed in the assembly hole 43 of pole socket 4 and to be fixed by hole shelves 6, the bottom surface 41 that described spring 1 is installed in pole socket 4 is connected on the base plate 21 of throttle shaft 2, and the center line of described spring 1 is overlapping with the center line of the assembly hole 43 of described pole socket 4.The containing space of described guideway 5, the assembly hole 4 of described pole socket 4 are overlapping with the center line of the accepting hole 23 of described throttle shaft 2.The side plate 22 of described throttle shaft 2 is provided with some holes 25 of arranging up and down away from the position of window 24.Described throttle shaft 2 is assembled in the containing space of guideway 5 and also can relatively moves up and down by guideway 5.Described axle shelves 3 are assembled in throttle shaft 2, and when relatively guideway 5 moves downward certain position to throttle shaft 2, axle shelves 3 are kept out on guideway 5, and the continuing of restriction throttle shaft 2 moves downward.
When the utility model cushioning device for oil cylinder uses, fluid is full of in the assembly hole 43 of pole socket 4 and the accepting hole 23 of throttle shaft 2, throttle shaft 2 relatively guideway 5 moves upward, spring 1 is compressed, some holes 25 on the side plate 22 of throttle shaft 2 are successively directed to axle sleeve 5 and close, in the process, fluid in the accepting hole 23 of throttle shaft 2 is squeezed outside throttle shaft 2 from described hole 25, because the quantity in the hole 25 of the side plate 22 of orifice size and throttle shaft 2 is proportional, therefore, the increase of the quantity that orifice size can make described hole 25 close along with the increase of the Bottom Runby of pole socket 4 and diminishing gradually, flow resistance is then along with the increase of the closedown quantity in described hole 25 increases gradually, then the downstream rate of pole socket 4 is also slack-off gradually, pole socket 4 is finally made to get back to terminal gently, spring 1 is made pole socket 4 move upward some holes 25 of opening on the side plate 22 of throttle shaft 2 by the elastic force after compressing.Due to the throttle shaft 2 of the utility model cushioning device for oil cylinder arranging some holes 25, adopting porous variable flow resistance technology, pole socket 4 being slowed down mild without impacting.
These are only preferred embodiment of the present utility model, other any improvement conversion done on the present embodiment basis also should not depart from the technical solution of the utility model.
