Abstract

The invention discloses a built-in guide oil cylinder. The built-in guide oil cylinder comprises a lower end cover, cylinder barrels, an upper end cover, a plunger piston, upper screws, lower screws and a guide block. According to the built-in guide oil cylinder, a guide device is mounted in an oil cylinder; as the oil cylinder moves, the effect of radially guiding the oil cylinder in moving can be improved, and moreover, the rotating of the oil cylinder is limited, and the circumferential guide for the oil cylinder can be reliably achieved. The built-in guide oil cylinder is simple in structure, and reliable in work; the problem of limitation on a mounting space and mounting conditions of the guide device for external accessories of the oil cylinder can be solved; the built-in guide oil cylinder can be applied to the occasion where the oil cylinder is limited to circumferentially rotate during the moving process; the built-in guide oil cylinder has a good 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...

Embodiment Construction

[0014] Such as figure 1 , figure 2 As shown, a built-in guide cylinder includes a lower end cover 1, a cylinder barrel 2, an upper end cover 3, a plunger 4, an upper screw 5, a lower screw 6 and a guide block 8. The lower end cover 1 is provided with a lower end cover oil cavity 1-1 in the middle and upper part, and a lower end cover oil inlet 1-3 and a lower end cover oil passage hole 1-2 are opened on the left side, and the lower end cover oil inlet 1-3 is connected through the lower end cover. The oil hole 1-2 communicates with the oil chamber 1-1 of the lower end cover, and the lower end cover sealing ring 1-4 is installed on the outer peripheral wall of the upper part of the lower end cover 1; The middle part is provided with a cylindrical hole 2-2 in the middle of the cylinder, and the upper part is provided with a cylindrical hole 2-3 in the upper part of the cylinder. The cylindrical hole 2-2 in the middle of the cylinder is respectively connected with the lower cyli...
