Background technology
Amortisseur, is under not affecting industrial equipment runnability premise, eliminates as increasing production efficiency, improves the impact of speed of service generation, vibrations, noise, guarantee safety, optimizes production environment.In prior art, conventional hydraulic damper, its structure is complicated, and control stability is poor, does not reach desirable damping effect.It addition, conventional amortisseur uses pot type piston, in use, its oil pressure is unstable, causes poor damping effect.
Summary of the invention
The applicant is for the shortcoming in above-mentioned existing production technology, it is provided that a kind of vibration damper for mechanical equipment high stability piston structure rational in infrastructure, thus improving control stability, and good damping effect.
The technical solution adopted in the present invention is as follows:
Vibration damper for mechanical equipment high stability piston structure, including cylinder body, is provided with piston in described cylinder body, described internal piston is inserted with push rod, and described push rod is cased with the first spring, and the rear end of described first spring is fixed on the afterbody of cylinder body by screw and O；Being also equipped with piston rod in described cylinder body, described piston rod becomes T-shaped structure, and described piston rod head end surface abuts with push rod, and described piston rod afterbody is provided with the second cylinder cap, and Capsule is installed in described second cylinder cap outer end；Described piston becomes cylindrical structure, and the outer circumference surface of described piston has screw thread oil groove；Gap is left between outer circumference surface and the inner peripheral surface of cylinder body of described piston.
Further improvement as technique scheme:
The structure of described push rod is: include push rod body, and described push rod body is provided with door, and described door one end is provided with packing ring；
The outer circumference surface of described cylinder body has helicitic texture.
Beneficial effects of the present invention is as follows:
Present configuration is compact, reasonable, the design of outside piston side face screw thread oil groove, it is possible to make it in use have the change of more stable oil pressure, thus ensure that the stability that amortisseur uses；Substantially increasing the overall performance of amortisseur, stable working is high, improves control stability, good damping effect.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, Figure 2 and Figure 3, the vibration damper for mechanical equipment of the present embodiment high stability piston structure, including cylinder body 1, piston 7 is installed in cylinder body 1, piston 7 is internal is inserted with push rod 14, being cased with the first spring 6 on push rod 14, the rear end of the first spring 6 is fixed on the afterbody of cylinder body 1 by screw 5 and O 13；Being also equipped with piston rod 2 in cylinder body 1, the T-shaped structure of 2 one-tenth of piston rod, piston rod 2 head end abuts with push rod 14, and piston rod 2 afterbody is provided with the second cylinder cap 3, and Capsule 4 is installed in the second cylinder cap 3 outer end；As shown in Figure 4,7 one-tenth of piston cylindrical structure, the outer circumference surface of piston 7 has screw thread oil groove 701；Gap is left between outer circumference surface and the inner peripheral surface of cylinder body 1 of piston 7.
As it is shown in figure 5, the structure of push rod 14 is: include push rod body 1401, push rod body 1401 being provided with door 1402, door 1402 one end is provided with packing ring 1403.
As it is shown in figure 1, the outer circumference surface of cylinder body 1 has helicitic texture.
As shown in Figure 3, the mounting structure of piston rod 2 is: be provided with energy-absorbing piston 11 by star circle 15 on piston rod 2, between left side and piston rod 2 head of energy-absorbing piston 11, first cylinder cap 8 is installed, energy-absorbing piston 11 is also equipped with sealing shroud 10 and the first elastic spring 9；Being positioned on the piston rod 2 of cylinder body 1 head and be provided with cylinder cap 16, cylinder cap 16 is fixed in cylinder body 1 by the second elastic spring 17, installs the second spring 12 between energy-absorbing piston 11 right-hand member and cylinder cap 16.
In actually used process, power actuated plunger bar 2 is moved to the left, piston rod 2 head abuts with push rod 14 and compresses, piston 7 is promoted to be moved to the left under force, now the first spring 6 compresses, the raw extruding of oily hair at piston 7 left end lumen portion, design due to piston 7 screw thread oil groove 701, now oil flows through piston 7 outer ring along screw thread oil groove 701, and oil order enters the oilhole of the first cylinder cap 8, compresses energy-absorbing piston 11, simultaneously, oil enters in sealing shroud 10, thus promoting energy-absorbing piston 11 to move right, extrudes the second spring 12.When piston rod 2 moves right, the first spring 6 and the second spring 12 reset.Thus reaching the effect of damping.
Above description is explanation of the invention, is not the restriction to invention, and limited range of the present invention is referring to claim, within protection scope of the present invention, it is possible to do any type of amendment.
