Abstract

The invention discloses an independent integrated hydraulic linear driving system which mainly comprises a hydraulic cylinder module, a hydraulic control integration module, a motor pump unit module and an energy accumulator module. The hydraulic cylinder module mainly comprises a tandem cylinder and a displacement sensor, the hydraulic control integration module mainly comprises a first pressure sensor, a second pressure sensor, a third pressure sensor, a throttle valve, a two-way electromagnetic ball valve, a first overflow valve, a second overflow valve, a first check valve, a second check valve, a three-way electromagnetic ball valve and a fourth pressure sensor, and the motor pump unit module mainly comprises a servo motor and a hydraulic pump. The independent integrated hydraulic linear driving system has the advantages that the independent integrated hydraulic linear driving system is based on modular and pipeline extremely simplified designs, is high in integration and can be independently used, movement control or force control can be carried out on actuator terminals, the independent integrated hydraulic linear driving system has accelerating and boosting functions, and processes for the independent integrated hydraulic linear driving system are flexible and excellent; volume control is carried out on linear hydraulic actuators, accordingly, the independent integrated hydraulic linear driving system is low in throttle loss, and heat rarely can be generated by the independent integrated hydraulic linear driving system; hydraulic pipeline mounting and laying work can be omitted when the independent integrated hydraulic linear driving system is used, accordingly, the designs of the independent integrated hydraulic linear driving system can be effectively simplified, the manufacturing cycle can be shortened, and the independent integrated hydraulic linear driving system is high in operational reliability and good in interchangeability and can bring convenience for mounting, maintaining and repairing work.

Description

technical field [0001] The invention relates to a hydraulic linear drive system, relates to a volume control hydraulic linear drive system, in particular to an independent integrated hydraulic linear drive system. Background technique [0002] Hydraulic linear drive technology is widely used in metal forming, testing, robotics and other fields, mostly involving non-standard occasions, often requiring custom-made special hydraulic systems, and the design and manufacturing cycle is long. The design and laying of hydraulic pipelines is cumbersome and time-consuming. Due to space constraints and other factors, hydraulic pipelines are not easy to maintain, and are prone to failures such as oil leakage. On the one hand, it may lead to a decrease in the cleanliness of the hydraulic oil and reduce the reliability of the hydraulic system. On the other hand, it also brings about environmental pollution. Contents of the invention [0003] The purpose of the present invention is to p...
