Fluid pressure delay transmission method, delay transmission mechanism and pressure delay execution system

Abstract

The invention discloses a fluid pressure delay transmission method, a delay transmission mechanism and a pressure delay execution system. Fluid enters a branch pipeline after starting from a fluid supply station: one path, flows to an execution mechanism through a one-way stop valve; the other path, flows to a delay drive mechanism through a throttle valve, the delay drive mechanism includes a first fluid accommodating cavity and a first piston rod assembly, the first piston rod assembly is connected to a valve core of the one-way stop valve, and the fluid enters the first fluid accommodatingcavity to drive the first piston rod assembly to act; and the throttle valve controls the flow rate of the fluid, the fluid drives the first piston rod assembly and the valve core to act through the first fluid accommodating cavity to enable the one-way stop valve to change from shutting off to turning on, so that the fluid flows into the execution mechanism from the one-way stop valve, the execution mechanism completes subsequent actions, and the time that the one-way stop valve changes from shutting off to turning on is the time for delay transmission. The fluid pressure delay transmission method, the delay transmission mechanism and the pressure delay execution system have the advantages that the method is simple and efficient, adjusting is convenient, comprehensive delay programming does not need to be carried out on the transmission mechanism and supporting equipment, and the production cost is saved.

Description

technical field [0001] The invention belongs to the technical field of fluid pressure actuating equipment, and in particular relates to a fluid pressure delay transmission method, a delay transmission mechanism with a fluid pressure delay transmission function and a pressure delay execution system with a transmission mechanism, in particular to a hydraulic cylinder / pneumatic cylinder Delay execution of cylinder action. Background technique [0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It has simple structure and reliable operation. When it is used to realize reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable, so it is widely used in various mechanical hydraulic systems. The output force of the hydraulic cylinder is proportional to the effective area of ​​the piston and the pressure...

[0006] In order to solve the delay problem of the follow-up action of the hydraulic cylinder or pneumatic cylinder in the prior art, the timing programming of the action delay logic is carried out in the controller to control the operation mode of the oil supply or air supply device, so that the pressure control valve reaches the starting pressure time delay, so as to realize the problems existing in the control method of hydraulic cylinder or pneumatic cylinder to complete the follow-up delay action. The purpose of the present invention is to provide a fluid pressure delay transmission method, a delay transmission mechanism and a pressure delay execution system. The method is simple and efficient, easy to adjust, and does not need to carry out comprehensive delay programming on the transmission mechanism and supporting equipment, saving production costs; the transmission mechanism has a simple structure and stable operation, and does not need to perform timing programming of action delay logic in the controller, reducing the It is difficult to control the logic when other automation equipment is matched, and the control of action delay can be adjusted manually, so that the adjustment of action delay matching with other automation equipment can be completed in a short period of time during the equipment debugging process, with high work efficiency and low manufacturing cost.
