Abstract

The invention discloses an electric boosting hydraulic cylinder and a boosting method thereof. A first thickened piston is arranged in the upper chamber of a cylinder body; a second piston is arranged in lower chamber of the cylinder body; a ball screw nut on the lower part of a ball screw is connected integrally with the first thickened piston; a servo motor is connected outside the upper part of the ball screw; a piston rod is connected below the second piston; the piston rod extends out of the cylinder by passing through the bottom of the cylinder; the piston rod is used for applying force outwards during working of the hydraulic cylinder; the second piston is connected more than two pull rods; each pull rod passes through the cylinder body and the first thickened piston, and is connected with the lower ends of filling rods; the upper ends of the filling rods pass through a cylinder cover; the total sectional area of more than two filling rods is equal to the sectional area of the piston rod; the sectional area of the second piston is larger than the sectional area of the piston rod of the first thickened piston. Hydraulic boosting is realized, the structure is simple, complex pumps, valves and the like are not needed, convenience is brought to maintenance, and a better working effect can be achieved by improving in a plurality of forms.

Description

technical field [0001] The invention belongs to the technical field of hydraulic cylinder manufacturing, and in particular relates to an electric pressurized hydraulic cylinder and a pressurization method thereof. 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). The traditional hydraulic cylinder has a complex structure and troublesome assembly. The hydraulic pump station is a key component of the traditional hydraulic cylinder, which provides power for the work of the hydraulic cylinder, but it occupies a large area and is expensive, and requires a separate pipeline to connect to the hydraulic cylinder. The work of traditional hydraulic cylinders is inseparable from a large number of hydraulic valves and hydraulic pipelines, but these will increase the complexity of the hydraulic cylinder and increase the production cost.
