Abstract

The invention discloses a built-in guide oil cylinder which comprises a lower end cover, a cylinder barrel, a right guide rod, a left guide rod, an upper end cover, a plunger piston and the like. A guide device is mounted inside an oil cylinder, so that in a movement process of the oil cylinder, on one hand, radial guide effect of the oil cylinder is reinforced, on the other hand, rotation of the oil cylinder is restricted, and therefore, circumferential-direction guide of the oil cylinder is reliably realized. The built-in guide oil cylinder is simple in structure, reliable in work, solves the problem that a guide device for external accessories of the oil cylinder is limited by a mounting space and conditions, can be applied to limiting a circumferential-direction rotation occasion in a movement process of the oil cylinder, and has a wide 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...
