The invention discloses an integrated variable-damping hydraulic support system. The integrated variable-damping hydraulic support system comprises a hydraulic cylinder and a follow-up support head, wherein a rodless cavity oil pipe is connected with an oil port of a rodless cavity of the hydraulic cylinder, a first overflow valve and an oil tank in sequence; a rod cavity oil pipe is connected with an oil port of a rod cavity of the hydraulic cylinder, a second overflow valve and the oil tank in sequence; a first oil port of a two-way pump is connected with the rod cavity oil pipe, a one-way valve, an oil filter and the oil tank in sequence through a first oil pipe; a second oil port of the two-way pump is connected with the rodless cavity oil pipe, a hydraulic control one-way valve and the oil tank in sequence through a second oil pipe; a control oil way of the hydraulic control one-way valve is connected to the rod cavity oil pipe; the two-way pump is connected with a servo motor; a displacement sensor is inserted in the rodless cavity of the hydraulic cylinder; a controller is connected with the displacement sensor, and acquires displacement signals of the hydraulic cylinder through the displacement sensor and outputs rotating speed control signals of the servo motor according to the displacement signals; and a hydraulic rod of the hydraulic cylinder is fixedly connected with the follow-up support head. The system can effectively restrain the flutter of thin-wall parts.
Description
technical field [0001] The invention relates to the technical fields of electro-hydraulic control and mirror image processing, in particular to a hydraulic support system for supporting thin-walled parts with weak rigidity during mirror image processing. Background technique [0002] Due to the characteristics of high efficiency, economy and environmental protection of mirror image processing, this processing method has been more and more applied to the processing of thin-walled parts. The mirror processing system has a processing mechanism and a supporting mechanism that are symmetrically arranged on both sides of the thin-walled part and move synchronously. Due to the weak rigidity of thin-walled parts, deformation and chatter will occur during processing. The support mechanism is to suppress chatter, improve rigidity, and improve machining accuracy. [0003] The hydraulic support system has been widely used in thin-walled flexible tooling due to its characteristics of st...
