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 cover, a cylinder barrel, an upper end cover, a plunger, an upper screw, a lower screw, a guiding rod, a right guiding block, a left guiding block, a key and a guiding block installation screw. According to the built-in guiding oil cylinder, a guiding device is installed inside the oil cylinder; on one hand, the radial guiding function of the oil cylinder is improved in the movement process of the oil cylinder; on the other hand, the rotation of the oil cylinder is limited, and the circumferential guiding of the oil cylinder is achieved reliably. The built-in guiding oil cylinder is simple in structure and reliable in working, the problem that the installation space and conditions of external accessories and the guiding device of the oil cylinder are limited is solved, the built-in guiding oil cylinder can be applied to the occasion of circumferential rotation in the process of limiting the movement of the oil cylinder, and broad application prospects are achieved.

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...
