Description

Damp type piston rod
Technical field
The present invention relates to a kind of piston rods.
Background technique
Machinery industry in constantly development and progress, mechanical equipment using more and more extensive, these equipment are in different works Work under condition generation oscillation degree it is different, normal damper cannot adjust damping force as needed can reduce the use of equipment In the service life, it also will affect the using effect of equipment, control stability is poor.
Summary of the invention
It is adjustable that invention is related to a kind of damping force, adapts to distinct device needs, effectively improves the stabilization of mechanical equipment Property, so that product is obtained gentle mechanical movement, promotes the quality of product and the damp type piston rod in service life.
In order to achieve the above object, the technical scheme is that a kind of damp type piston rod, including cylinder body, piston rod And piston, piston rod protrude into cylinder body, and piston is fixedly connected on the end of piston rod, and slides and connect with cylinder body, piston will Cylinder body is divided into pressure chamber and working chamber, is full of fluid media (medium) in pressure chamber, further includes driving motor and rotating disc, the driving electricity Machine is fixedly connected on piston, and drives turn disc, and rotating disc is equipped with axial recirculation hole, and piston is equipped with multiple straight The different damping hole of diameter.
Preferably, the damping hole there are four diameter less than recirculation hole is set on the piston.
Preferably, the diameter of four damping holes is 10cm, 15cm, 20cm and 25cm respectively, and the diameter of recirculation hole For 30cm.
Preferably, it is equipped with seal groove between each damping hole on the piston, is equipped with sealing strip in seal groove.
Preferably, the outer end of the cylinder body and piston rod is equipped with universal joint.
After adopting the above structure, with the recirculation hole of fixed diameter on rotating disc of the invention, and piston is equipped with multiple The different damping hole of diameter, when driving motor drives turn disc, it is different that the recirculation hole on rotating disc can be directed at diameter Damping hole, when piston moves in cylinder body, fluid media (medium) will enter working chamber from pressure chamber by recirculation hole and damping hole It is interior, and the damping hole of different-diameter will provide different damping forces, have the function that adjust damping, adapting to distinct device needs It wants, effectively improves the stability of mechanical equipment, product is made to obtain gentle mechanical movement, promote quality and the longevity of product Life.
Detailed description of the invention
Fig. 1 is schematic diagram of the invention;
Fig. 2 is the top view of piston in Fig. 1.
Specific embodiment
The present invention is described in further detail for the embodiment provided below in conjunction with attached drawing.
Ginseng as shown in FIGS. 1 and 2, a kind of damp type piston rod, including cylinder body 1, piston rod 2 and piston 3, piston rod 2 protrude into cylinder In body 1, and piston 3 is fixedly connected on the end of piston rod 2, and slides and connect with cylinder body 1, and piston 3 divides cylinder body 1 for pressure chamber 11 and working chamber 12, fluid media (medium) is full of in pressure chamber 11, further includes driving motor 4 and rotating disc 5, the driving motor 4 is solid Surely be connected on piston 3, and rotating disc 5 driven to rotate, rotating disc 5 is equipped with axial recirculation hole 6, set on piston 3 there are four The different damping hole 7 of diameter.
Referring to being set shown in Fig. 1 and 2 on the piston 3, there are four the damping holes 7 that diameter is less than recirculation hole 6.If damping hole 7 are greater than recirculation hole 6, then damping force can also remain unchanged, and not have the effect of damping.
The diameter of four damping holes 7 of the embodiment of the present invention is 10cm, 15cm, 20cm and 25cm respectively, and recirculation hole 6 Diameter is 30cm.Therefore four kinds of different dampings can be provided.
It is shown in Figure 2, it is equipped with seal groove 8 between each damping hole 7 on the piston 3, is equipped in seal groove 8 close Strip of paper used for sealing.It needs to seal between piston 3 and rotating disc 5, if sealing is bad, fluid media (medium) will be flowed through from four damping holes 7, The effect for adjusting damping is not had.
The outer end of the cylinder body 1 and piston rod 2 shown in Figure 1 is equipped with universal joint 9.Universal joint 9 can connect Distinct device is connect, angle can adjust at any time.
Referring to shown in Fig. 1 and 2, with the recirculation hole 6 of fixed diameter on rotating disc 5 of the invention, and piston 3 is equipped with four The different damping hole 7 of a diameter, driving motor 4 are fixed on piston 3, and rotating disc 5 is fixedly connected on the output shaft of driving motor 4 On, and rotating disc 5 and piston 3 are close to each other, and rotating disc 5 is located in pressure chamber 11.The wiring of driving motor 4 is critically important, needs The end cap that pass through piston 3 and cylinder body 1, keeps sealing.Stream when driving motor 4 drives rotating disc 5 to rotate, on rotating disc 5 Through-hole 6 can be directed at the different damping hole 7 of diameter, and when piston 3 moves in cylinder body 1, fluid media (medium) will be logical from pressure chamber 11 It crosses recirculation hole 6 and damping hole 7 enters in working chamber 12, and the damping hole 7 of different-diameter will provide different damping forces, reach The effect for adjusting damping, adapts to distinct device needs, effectively improves the stability of mechanical equipment, obtains product gentle Mechanical movement, promote quality and the service life of product.
What has been described above is only a preferred embodiment of the present invention, it is noted that for those of ordinary skill in the art For, without departing from the concept of the premise of the invention, various modifications and improvements can be made, these belong to the present invention Protection scope.
