Abstract

The invention discloses a built-in guide oil cylinder comprising a lower end cover, a cylinder barrel, a right guide rod, a left guide rod, an upper end cover, a plunger and the like. A guide device is arranged inside the oil cylinder, on one hand, the radial guide effect of the oil cylinder is improved in the motion process of the oil cylinder, and on the other hand, the rotation of the oil cylinder is limited in the motion process of the oil cylinder, so that the circumferential guide of the oil cylinder is reliably realized. The built-in guide oil cylinder is simple in structure, reliable in work, capable of solving the problem of mounting space and condition limitation of the guide device serving as an outer accessory and wide in application prospect and can be applied to occasions where circumferential rotation is limited in the motion process of the oil cylinder.

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...
