Problems solved by technology

[0003] The purpose of the present invention is to make the piston of the double-acting cylinder arbitrarily change and adjust its action position according to the working conditions by using the simple electrical control mechanism of the position sensor and the solenoid valve, and solve the problem of the lifting speed in the vertical load well. The problem of inconsistency and rebound force during emergency stop keeps the piston movement stable and balanced and precise position control

Abstract

The invention aims at providing a positioning control mechanism of a vertical load for a double-acting cylinder (13). A three-position five-way electromagnetic valve for air supply (4) is connected to an air inlet and outlet opening (6) of an air-liquid converter (7) and an air inlet and outlet opening (12) of a double-acting cylinder, and a stopping electromagnetic valve (9) is connected between a liquid inlet and outlet opening (8) of the air-liquid converter and a liquid inlet and outlet opening (10) of the double-acting cylinder. The control mechanism is provided with a position sensor (15) for detecting the position of a cylinder piston and an electrical control system (3), wherein the electrical control system (3) controls the opening and the closing of the electromagnetic valves according to the piston position (11) detected by the position sensor (15), and stably moves the cylinder piston to the target position, so that the cylinder piston is stopped and kept at the stopping position.

Description

technical field [0001] The present invention relates to a positioning control mechanism, in particular to a positioning control mechanism in the vertical load state of a double-acting cylinder. positioning control. Background technique [0002] In general, the stroke of the piston in the double-acting cylinder is mainly determined by mechanical means such as the position of the forward end and the backward end or a stopper, and it is difficult to arbitrarily change and adjust the moving position of the piston, especially when the cylinder is in the In the state of loading objects or workpieces in the vertical direction, due to the problems of slow rising speed, fast falling speed and upward rebound force when the cylinder stops suddenly, it is difficult to accurately control the action position of the cylinder piston. Contents of the invention [0003] The purpose of the present invention is to make the piston of the double-acting cylinder arbitrarily change and adjust it...
