Abstract

The invention discloses damping hydraulic cylinder. The cylinder comprises a damping cylinder, the damping cylinder comprises a first cylinder body, a first piston and a first piston rod are arranged in the first cylinder body, the first cylinder body is divided into a first rodless cavity and a first rod cavity through the piston and the piston rod, the damping cylinder is connected with a balance cylinder, the balance cylinder comprises a second cylinder body, a second piston and a second piston rod are arranged in the second cylinder body, the second cylinder body is divided into a second rodless cavity and a second rod cavity through the second piston and the second piston rod, an elastic piece is connected between the second piston and the second cylinder body, the second rod cavity communicates with outside air, the first rodless cavity communicates with the second rodless cavity through a damping oil way, the first cylinder body is provided with a communicating oil way communicating the first rodless cavity with the first rod cavity, and a closed oil cavity is formed among the first rodless cavity, the first rod cavity, the damping oil way, the communicating oil way and the second rodless cavity. By means of the mode, the damping hydraulic cylinder can avoid unbalanced oil cavity pressure caused by the backpressure problem, and buffering stability is maintained.

Description

technical field [0001] The invention relates to the field of cylinders, in particular to a damping hydraulic cylinder for the cylinder. Background technique [0002] In pneumatic automation systems, vibration and shock phenomena are frequent. A cylinder moving at high speed produces a large impact force at the end of the stroke. In order to prevent the cylinder piston from hitting the cylinder head at the end of the stroke, a buffer device is generally provided. [0003] The hydraulic damper can convert more than 90% of the impact energy into oil heat energy and dissipate it through throttling absorption, and the buffer efficiency and attenuation coefficient are greatly improved compared with traditional buffers. [0004] The most commonly used hydraulic damper is to add a damping pipe between the two chambers, or add a flow regulating valve to the connecting oil pipe, and achieve the damping effect through hydraulic oil or a flow regulating valve; or make the hydraulic da...
