Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 1, Figure 2 and Figure 3, the vibration damper for mechanical equipment of the present embodiment energy-absorbing 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; Piston rod 2 it is also equipped with 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, piston rod 2 is provided with energy-absorbing piston 11 by star circle 15, 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 at cylinder body 1 head place 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; Piston rod 2 end 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, the structure of energy-absorbing piston 11 is: the stepped structure of energy-absorbing piston 11, including first step 1101, second step 1103 and the 3rd step 1104, draw-in groove 1102 it is formed with between first step 1101 and second step 1103, sealing shroud 10 is installed at draw-in groove 1102 place, and the outer circumference surface of first step 1101 is installed the first elastic spring 9.
