A travel control universal strain angle hydraulic cylinder

Abstract

The invention relates to a stroke control universal strain angle hydraulic oil cylinder. The oil cylinder is a universal swing hydraulic plunger oil cylinder composed of a shell, a gland, a cylinder body and a piston rod, a cavity with the inner spherical face is formed by the shell and the gland, and is matched with a cylinder body with the outer spherical face, and therefore a centripetal universal spherical face swing mechanism is formed. A columnar cavity is formed in the spherical cavity and is matched with a rod body which can do reciprocating motion along the columnar cavity to form a plunger oil cylinder, pressure enters a flow way through a hydraulic input connector formed in the outer side of the shell to pass through a stroke hydraulic control one-way valve to flow into the cylinder body so as to act on the inner end of a rod body, acting force of F is output in a motion manner, and when the pressure is unloaded, a stretched large spring enables the rod body to returned to the initial state. The plunger oil cylinder carries out strain on the contact face of the shell with the inner spherical face and can do centripetal universal swing reciprocating linear motion along the sphere end face perpendicular to the cylinder body. The stroke hydraulic control one-way valve is in the closed state, a closed oil way when a rod body stretches out the stroke S is synchronized, and the swing angle alpha is associated with the position, higher than the end face of the gland, of the spherical face of the cylinder body.

Description

technical field [0001] The invention relates to a travel-controlled universal strain angle hydraulic oil cylinder, which belongs to the field of engineering hydraulic oil cylinders. Background technique [0002] At present, the working principle and requirements of hydraulic cylinders at home and abroad are to avoid radial force as much as possible, and the cylinder rod body does a linear axial movement to push (pull) the force. However, when the object being lifted is deformed or tilted, an angle will be formed between the object and the surface of the ejector rod, so various connection methods are adopted. Its purpose is to make the oil cylinder work, under the state of guiding and strain action points, not to receive or reduce the radial side force of the oil cylinder, and not to generate bending force, so as to ensure the normal use and life of the oil cylinder. [0003] In actual operation, the movement of the oil cylinder often has misoperations that exceed the stroke...
