Abstract

The invention belongs to the technical field of hydraulics, and provides a mechanical-hydraulic servo type hydraulic cylinder automatic resetting and sequence control device, which comprises a mechanical-hydraulic servo positioning valve and a feedback slide block, wherein the positioning valve comprises a valve body, a valve sleeve, a valve core, a left end cap, a right end cap, an ejector rod, a spring, a pressure reducing valve, a throttling element 1, a throttling element 2, a spring sleeve, a pull rod, a roller and a pin. The mechanical-hydraulic servo type hydraulic cylinder automatic resetting and sequence control device has the advantages that the problems of automatic positioning of the position of a hydraulic cylinder and the sequence control related with the positions of positioning points are solved by a pure mechanical method, the reliability is high, and the flexibility is high.

Description

technical field [0001] The invention belongs to the technical field of hydraulic pressure, and relates to an automatic reset and sequence control device for a hydraulic cylinder of a machine-hydraulic servo, and is especially suitable for the occasion in a hydraulic system where the piston rod of the hydraulic cylinder needs to be positioned at a certain point and the next sequential action is triggered. Background technique [0002] The positioning of the hydraulic cylinder in the prior art usually requires the use of electrical sensors and electrical control, which is not reliable, and its sequence control is generally realized by electrical methods or sequence valves, which is not reliable and flexible. Contents of the invention [0003] The purpose of the present invention is to solve the automatic positioning of the position of the hydraulic cylinder and the sequence control problem related to the position of the positioning point. The invention adopts a purely mecha...
