Problems solved by technology

In some special occasions, the space and conditions for setting up an additional external guide device cannot be met. Therefore, it is necessary to consider installing a guide device inside the oil cylinder to ensure the guide function of the oil cylinder and prevent the circumferential rotation of the oil cylinder.

Abstract

The invention discloses a built-in guiding oil cylinder which comprises a lower end cap, a cylinder barrel, an upper end cap, a piston, a piston rod, upper screws, a lower screw, a guiding rod, a guiding block and a key. According to the invention, the guiding device is mounted in the oil cylinder, which enhances the radial guiding function of the oil cylinder on one hand, and limits the rotation of the oil cylinder and reliably realizes the circumferential guiding of the oil cylinder on the other hand during the operating process of the oil cylinder. The built-in guiding oil cylinder is simple in structure, works reliably, solves the problem that the mounting space and condition of an external accessory guiding device of an oil cylinder are limited, can be applied to the occasion of limiting circumferential rotation during an oil cylinder operating process, and has a wide application prospect.

Description

technical field [0001] The invention relates to a guide oil cylinder, in particular to a built-in guide oil cylinder with a guide device installed inside the oil cylinder, and belongs to the technical field of electric and electromechanical technology. Background technique [0002] At present, hydraulic cylinders have been widely used in various types of mechanical equipment. In common application environments, hydraulic cylinders are used to achieve linear motion through relatively large working forces. The guiding problem of the cylinder during the linear motion is mostly realized by setting guide rings or guide belts in the cylinder end cover and on the piston. Setting guide rings or guide belts in the cylinder end cover and on the piston cannot solve the problem of the cylinder For the problem of the circumferential rotation of the piston rod or plunger, when it is necessary to limit the circumferential rotation of the oil cylinder, an additional guide device is often pr...
