Abstract

The invention relates to a hydraulic damping device with adjustable damping force. The hydraulic damping device comprises a cylinder body, a piston pipe, a piston, a pin rod, a positioning ring, an opening sealing ring, a cavity sealing ring, a pin rod sealing ring, a guide sleeve and liquid. The piston provided with a taper hole is connected to the end, located in the cylinder body, of the piston pipe, the outer cylindrical face of the piston is provided with a through hole penetrating through the outer cylindrical face and a center hole, the cavity sealing ring is arranged on an annular groove of the piston in a sleeved mode and divides an inner cavity of the cylinder body into an upper cavity and a lower cavity, and one end of the pin rod penetrates through an inner hole of the piston pipe, extends into the piston and is in threaded connection with the piston. The rod end of the pin rod is in clearance fit with the taper hole of the piston, the pin rod can move in the axial direction of the piston pipe when the pin rod is rotated, and therefore the fit clearance between the taper hole of the piston and the rod end of the pin rod can be adjusted, and the damping force can be adjusted. The mechanism is simple and reliable, and the damping force can be adjusted according to the load when the mechanism is applied to a mechanical device.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a hydraulic damping device for buffering a moving mechanism. Background technique [0002] The existing hydraulic damping device with adjustable damping force uses the matching gap between the piston rod and the piston as the overflow path of the liquid to provide the damping force, and the matching gap between the piston rod and the piston can be adjusted by rotating the piston rod, thereby adjusting the damping force. The problem of this type of damping device is that when the piston rod is rotated, the length of the piston rod extending out of the cylinder will change. In some applications that require the length of the piston rod, this type of damping device is not suitable. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a hydraulic damping device with adjustable damping force in order to solve the above problems. To achieve the above object, ...
