Embodiment Construction

[0012] like figure 1 As shown, the present invention is a hydraulic servo drive system for a precision model support device, including two groups of hydraulic cylinders 1 connected to the swinging member 9 and the fixing member 10, and each group of hydraulic cylinders 1 is correspondingly connected to a servo valve 5 , each group of hydraulic cylinders 1 controls the motion state through its own servo valve, each group of hydraulic cylinders 1 is equipped with a displacement sensor 2 and a pressure sensor 3, and the real-time position feedback is performed through the displacement sensor 2, and the hydraulic cylinder 1 is output through the pressure sensor. Each group of hydraulic cylinders 1 is equipped with an explosion-proof valve 8 at the connection port to prevent abnormal movement of the equipment when the connecting pipeline is damaged. A hydraulic lock 4 is installed between each group of hydraulic cylinders 1 and its corresponding servo valve 5, and Controlled by th...

Abstract

The invention discloses a hydraulic servo drive system for a precision model support device. The hydraulic servo drive system comprises two hydraulic cylinders connected with swinging members and fixed members. Each hydraulic cylinder is correspondingly connected with a servo valve, and a displacement sensor and a pressure sensor are mounted on each hydraulic cylinder The hydraulic servo drive system has the beneficial effects that the static and dynamic characteristic indexes are increased, the structural support rigidity is improved, the stability is better, the position control precision ishigher, and the accuracy of test data is improved.

Description

technical field [0001] The invention relates to the field of hydraulic servo drive control, in particular to a hydraulic servo drive system for a precision model support device. Background technique [0002] When a precision model support device is used, in order to reduce the overall equipment size, it usually adopts a rotary motion joint driven by two hydraulic cylinders, such as figure 2 As shown, the two hydraulic cylinders are controlled by the same hydraulic valve, the support rigidity of the system is poor, and the motion control accuracy is low, which has a great impact on the test accuracy data. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings, provide a hydraulic servo drive system for precision model support devices, and solve the disadvantages of poor support rigidity and low motion accuracy of the device. [0004] The technical solution adopted by the present invention to achieve the above...
