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 an internal guide oil cylinder. The internal guide oil cylinder comprises a lower end cover, a cylinder barrel, an upper end cover, a plunger, an upper screw, a lower screw, a guide rod, a guide block and a key. According to the internal guide oil cylinder disclosed by the invention, a guiding device is mounted inside the oil cylinder; on one hand, the radial guidance effect of the oil cylinder is enhanced during a movement process of the oil cylinder; on the other hand, rotation of the oil cylinder is limited, so circumferential guidance of the oil cylinder is reliably realized. The internal guide oil cylinder disclosed by the invention is simple in structure, reliable in work, capable of solving the problem that the installation space and condition of an external accessory guiding device of the oil cylinder are limited, applicable to occasions where the circumferential rotation of the oil cylinder is limited during the movement process, and wide in application prospect.

Description

Technical field [0001] The invention relates to a guiding oil cylinder, in particular to a built-in guiding oil cylinder with a guiding device installed inside the oil cylinder, and belongs to the electrical and electromechanical technical field. Background technique [0002] At present, hydraulic cylinders have been widely used in various mechanical equipment. Under ordinary application environments, hydraulic cylinders can be used to achieve linear motion through greater working force. Most of the guiding problems of the oil cylinder during the linear movement are realized by setting guide rings or guide belts in the cylinder end cover and on the piston. The setting of guide rings or guide belts in the cylinder end cover and on the piston cannot solve the problem of the oil cylinder. For the problem of the circumferential rotation of the piston rod or plunger, for occasions where the circumferential rotation of the cylinder needs to be restricted, additional guiding devices are...
