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.

The invention discloses an oil cylinder with an internal guiding device. The oil cylinder with the internal guiding device comprises a lower end cover, a cylinder barrel, an upper end cover, a plunger, upper screws, lower screws, a right guiding block, a left guiding block and guiding block installation screws. According to the oil cylinder, the guiding device is installed inside the oil cylinder, so that in the movement process of the oil cylinder, the radial guiding function of the oil cylinder is enhanced on one hand, and on the other hand, rotation of the oil cylinder is limited, and circumferential guiding of the oil cylinder is reliably achieved. The oil cylinder with the internal guiding device is simple in structure and reliable in work, and the problem that the installation space and condition of an external accessory guiding device of the oil cylinder are limited is solved; the oil cylinder with the internal guiding device can be applied to the occasion that circumferential rotation of the oil cylinder needs to be limited in the movement process of the oil cylinder and has broad application prospects.
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...
