[0002] In the working environment of construction machinery, the hydraulic system has been widely used because of its convenient operation and effective overload protection. Among them, the hydraulic cylinder is an important executive element of the hydraulic system. In the working environment of construction machinery, It has become an indispensable and important part, but due to the structural limitations of the hydraulic cylinder, the stroke and installation distance of the cylinder are fixed after the cylinder is formed, and it is difficult to change it. There is mutual correlation between them, and there are multiple working positions of the oil cylinder. At this time, through manual control, not only need to control multiple oil cylinders separately, but also it is difficult to accurately control the positioning, and there is a huge deviation

Embodiment Construction
[0014] In order to make the implementation technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific illustrations.
[0015] Such as Figure 1~2 as shown,
[0016] This embodiment provides a multi-cylinder associated precise positioning system, including a three-chamber cylinder 1 for precise positioning adjustment, a control device 2 connected to the three-chamber cylinder 1, and an associated cylinder 3 connected to the control device 2. The three-chamber The oil cylinder 1 includes a cylinder body 11 and an inner piston rod 12 and an outer piston rod 13 arranged in the inner cavity of the cylinder body 11, and the inner cavity of the cylinder body 11 is separated by the inner piston rod 12 and the outer piston rod 13 to form a first cavity 14. The second cavity 15 and the third cavity 16, the first cavity 14, the second cavity 15 and the third c...

The invention provides a multi-oil-cylinder associated precise positioning system. The system comprises a three-cavity oil cylinder used for precise positioning and adjusting, a control device connected with the three-cavity oil cylinder and an associated oil cylinder connected with the control device, and the three-cavity oil cylinder comprises a cylinder body, and an inner piston rod and an outer piston rod which are arranged in an inner cavity of the cylinder body; the three-cavity oil cylinder is provided with the inner piston rod and the outer piston rod which are transversely arranged, the inner cavity of the three-cavity oil cylinder is divided into a first cavity body, a second cavity body and a third cavity body through the inner piston rod and the outer piston rod, and feeding control is conducted through pressure oil of the three cavity bodies, so that the inner piston rod and the outer piston rod of the three-cavity oil cylinder are controlled to move telescopically; and ahydraulic reversing valve is controlled through the associated oil cylinder to achieve locking after the internal piston rod is positioned, the external piston rod can continue to stretch out to a designed stroke, and controllable accurate positioning adjustment of the oil cylinder is achieved.
Description
technical field [0001] The invention relates to the technical field of hydraulic control of engineering machinery, in particular to a multi-cylinder associated precise positioning system. Background technique [0002] In the working environment of construction machinery, the hydraulic system has been widely used because of its convenient operation and effective overload protection. Among them, the hydraulic cylinder is an important executive element of the hydraulic system. In the working environment of construction machinery, It has become an indispensable and important part, but due to the structural limitations of the hydraulic cylinder, the stroke and installation distance of the cylinder are fixed after the cylinder is formed, and it is difficult to change it. There is mutual correlation among them, and there are multiple working positions of the oil cylinder. At this time, through manual control, it is not only necessary to control multiple oil cylinders separately, bu...
