Abstract

The invention discloses an oil cylinder group capable of realizing synchronous movement. The oil cylinder group capable of realizing synchronous movement comprises a single piston rod oil cylinder, one or more double piston rod oil cylinders, a plunger oil cylinder and a reversing valve. The reversing valve, the single piston rod oil cylinder, the double piston rod oil cylinders and the plunger oil cylinder are sequentially connected. The single piston rod oil cylinder and the double piston rod oil cylinders are both provided with two main hydraulic fluid ports. A main hydraulic fluid port is arranged on a cylinder wall of the plunger oil cylinder. Compensating systems are arranged on the main hydraulic fluid ports of the single piston rod oil cylinder, the double piston rod oil cylinders and the plunger oil cylinder. The oil cylinder group capable of realizing synchronous movement provided by the invention has the advantages that a group of oil cylinders can move synchronously at a high degree, the cost of the oil cylinder system is low and the like.

Description

technical field [0001] The invention relates to an oil cylinder group capable of realizing synchronous movement. Background technique [0002] In today's machinery industry, there are many occasions in industrial equipment that require the synchronous action of two oil cylinders in order to increase the load. In general, it is necessary to use a variety of actuators to overcome the differences in load, friction, leakage, manufacturing quality, and structural deformation to ensure synchronization in motion. There are many forms, such as mechanical linkage, synchronous motor, and equal synchronization valve. etc. They have different influences on synchronization accuracy, complex structure, high cost, and whether they can prevent or eliminate error accumulation under deviation. [0003] In the prior art, multiple hydraulic cylinders in a synchronous oil cylinder often need to be controlled by multiple valves, which will cause problems such as complex structure and poor synchr...
