The invention discloses an oil way structure for achieving precise control of a double-acting oil cylinder. The oil way structure comprises the double-acting oil cylinder, an oil inlet line, an oil outlet line, a first energy accumulator, and a second energy accumulator, wherein an oil inlet is formed in one end of the oil inlet line, a first branch pipe and a second branch pipe are formed at theother end of the oil inlet line, the first branch communicates with a rod-free cavity, a first electromagnetic valve, the first energy accumulator and a first two-way flow control valve are arranged on the first branch pipe, the second energy accumulator is arranged in communication with the first branch pipe, the second branch pipe communicates with a rod cavity of the double-acting oil cylinder,a second electromagnetic valve is arranged on the second branch pipe, a second two-way flow control valve is arranged on the oil outlet line, one end of the oil outlet line is connected with an oil outlet, a third branch and a fourth branch are formed at the other end of the oil outlet line, the third branch is provided with a third electromagnetic valve and communicates with the second branch pipe, and the fourth branch communicates with the first branch pipe and is provided with a fourth electromagnetic valve. The oil way can achieve the precise control of the double-acting oil cylinder, islower in overall cost, and are more beneficial to popularization and promotion.
Description
technical field [0001] The invention relates to the technical field of oil cylinder control, in particular to an oil circuit structure for realizing precise control of a double-acting oil cylinder. Background technique [0002] A double-acting cylinder refers to a hydraulic cylinder that can input pressure oil from both sides of the piston. It is widely used in various fields. However, due to the difficulty of precise control of the output of the double-acting cylinder, it is difficult to be used in the field of precision machining. The movement is controlled within ±0.5mm. In order to achieve this kind of precise control, hydraulic servo control is usually used at present to achieve precise control of the movement of the piston rod of the servo cylinder. However, due to the high price of servo valves, electro-hydraulic proportional valves and servo cylinders, this control method has low cost performance and cannot be widely used. Contents of the invention [0003] Aim...
