Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
nullRefer to Fig. 1、Fig. 2，Embodiment of the present utility model provides a kind of hydraulic cylinder mechanism，Including cylinder barrel 1、The cylinder cap 2 being tightly connected with described cylinder barrel 1 one end、Can in described cylinder barrel 1 piston 3 of back and forth movement，It is provided with on described cylinder barrel 1 and passes in and out the Media Interface Connector 11 of cavity between described cylinder cap 2 and piston 3 for hydraulic medium，It is provided with a dashpot 21 on the end face of described cylinder cap 2 opposing pistons side，Described dashpot 21 is connected with described Media Interface Connector 11 by a buffer channel，Described buffer channel includes the transitional pore 12 being located on described cylinder barrel 1 and the cushion hole 22 being located on described cylinder cap 2，Described transitional pore 12 is axial arranged along described cylinder barrel 1 and one end connects with described Media Interface Connector 11、The other end connects with described cushion hole 22，Described cushion hole 22 one end connects with the cooperation of described transitional pore 12、The other end connects with described dashpot 21；Wherein, described relative cylinder cap 2 one end of piston 3 is provided with the buffering projection 31 matched with described dashpot 21.
Its specific works principle is as follows: piston 3 is under the driving of piston rod and external component, with high-speed motion near cylinder cap 2, hydraulic medium between piston 3 and cylinder cap 2 flows outwardly from Media Interface Connector 11, when buffering protruding 31 moves to the notch of dashpot 21, section hydraulic medium can be sealed between buffering protruding 31 and dashpot 21, and this section hydraulic medium can not directly be flowed out by Media Interface Connector 11, and need to flow back to Media Interface Connector 11 by buffer channel, owing to the aperture of cushion hole 22 is much smaller than Media Interface Connector 11, make the hydraulic medium sealed piston 3 can be produced bigger cushioned resistance, constantly reduce the piston 3 speed near cylinder cap 2, piston 3 is avoided to clash into cylinder cap 2, decrease piston 3 and the probability of cylinder cap 2 damage, extend the service life of hydraulic cylinder mechanism.
When specifically arranging, dashpot 21 can be arranged as required to, in order to ensure the harmony of cushion effect that piston 3 is subject to, avoid piston 3 each several part to accept inequality and and cause piston 3 the most uneven, described in the present embodiment, dashpot 21 is set to cross bath, it is protruding that corresponding buffering projection 31 is also configured as cross, to ensure to agree with mutually with cross bath.
Section hydraulic medium for the ease of sealing in dashpot 21 flows back to Media Interface Connector 11 smoothly, reduce the loss of hydraulic medium, the described cushion hole of this enforcement 22 includes the first all axially arranged along described cylinder cap 2 cushion hole 221 and the second cushion hole 222, and the 3rd cushion hole 223 being radially arranged along described cylinder cap 2, described first cushion hole 221 one end connects with in the middle part of described dashpot 21, the other end is connected with described second cushion hole 222 by described 3rd cushion hole 223, and described second cushion hole 222 other end connects with described transitional pore 12.By arrange with the first cushion hole 221 connected in the middle part of described dashpot 21 so that what the hydraulic medium sealed can equalize flows out from the first cushion hole 221, it is to avoid hydraulic medium outflow the unbalanced cushioned resistance causing piston 3 to be subject to unbalanced.Wherein, in order to ensure the outflow patency of hydraulic medium, described in the present embodiment, first cushion hole the 221, second cushion hole the 222, the 3rd cushion hole 223 is smooth connection.
Owing to the piston 3 hydraulic medium to sealing produces bigger extruding force, make hydraulic medium high speed and high-pressure flow in cushion hole 22, it is easily generated bigger jet power, for avoiding this jet power to damage Media Interface Connector 11, transitional pore 12 aperture described in the present embodiment is more than the aperture of described cushion hole 22, typically the aperture of cushion hole 22 is set to 5～15mm, and the aperture of transitional pore 12 is set to 20～60mm, concrete 2～4 times that general transitional pore 12 is cushion hole 22, with ensure hydraulic medium eject in cushion hole 22 after in transitional pore 12 flows decrease.
This utility model is by arranging the dashpot connected with Media Interface Connector on cylinder cap, piston arranges buffering projection, make piston when cylinder cap, section hydraulic medium can be sealed between dashpot and buffering projection, this section hydraulic medium can be flow back in Media Interface Connector again by buffer channel, but owing to the aperture of cushion hole is much smaller than Media Interface Connector, make the hydraulic medium sealed piston can be produced bigger cushioned resistance, piston is avoided to clash into cylinder cap, decrease piston and the probability of cylinder cap damage, extend the service life of hydraulic cylinder mechanism.
The above detailed description of the invention of the present utility model, is not intended that the restriction to this utility model protection domain.Any various other made according to technology of the present utility model design change and deformation accordingly, should be included in this utility model scope of the claims.
