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 guide oil cylinder which comprises a lower end cover, a cylinder barrel, an upper end cover, a piston, a piston rod, upper screws, lower screws, a guide rod, a right guide block, a left guide block, a key and guide block installing screws. According to the built-in guide oil cylinder, a guide device is installed in the oil cylinder, in the movement process of the oil cylinder, on one hand, the radial guiding action of the oil cylinder is enhanced, and on the other hand, rotation of the oil cylinder is limited, and circumferential guiding of the oil cylinder is reliably achieved. The built-in guide oil cylinder is simple in structure and reliable in work, solves the problem that the installing space and condition of the external accessory guide device of the oil cylinder are limited, can be applied to the occasions where circumferential rotating in the movement process of the oil cylinder is limited and has the 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...
