Oil cylinder with annular groove on cylinder barrel

Abstract

The utility model relates to an oil cylinder with an annular groove on a cylinder barrel, which comprises a rod cavity oil inlet, the cylinder barrel, an annular sleeve, the annular groove, a piston, a piston rod component and a rodless cavity oil inlet, and is characterized in that the annular sleeve is fixedly welded on the cylinder barrel and is provided with the annular groove; the annular groove serves as a reference and a fulcrum for positioning and fixing the oil cylinder with the annular groove on the cylinder barrel, and a flange, a support, a hinged shaft and the like can be positioned and fixed on the annular groove. The oil cylinder with the annular groove in the cylinder barrel is reasonable in design, compact in structure and convenient to operate and use.

Description

TECHNICAL FIELD

[0001] The utility model relates to an oil cylinder with annular grooves on the cylinder barrel. BACKGROUND

[0002] A kind of hydraulic cylinder, usually only one fixed mode, either pedestal installation, or flange installation or hinge shaft installation, but there are many times for the installation mode of on-site has no way to determine the case, when the installation mode and method of oil cylinder are not good to determine, oil cylinder design and manufacture have no way to determine, existing oil cylinder installation mode cannot meet the needs of now high efficiency work efficiency.Therefore the installation mode of existing hydraulic cylinder is limited, and needs improvement. SUMMARY

[0003] The utility model discloses a kind of oil cylinders with annular grooves on the cylinder barrel.

[0004] The utility model discloses the technical scheme that the technical problem thereof solves is: an oil cylinder with annular grooves on the cylinder barrel, comprising: rod cavity oil inlet 1, cylinder barrel 2, annular sleeve 3, annular groove 4, piston and piston rod assembly 5 and rodless cavity oil inlet 6, characterized by: annular sleeve 3 is fixedly welded on cylinder barrel 2, annular groove 4 is provided on annular sleeve 3, annular groove 4 is used as a kind of oil cylinder with annular grooves on the cylinder barrel positioning and fixed reference and fulcrum, flange, pedestal and hinge shaft can be positioned and fixed on annular groove 3.

[0005] The utility model has the beneficial effects that annular groove is used as reference and fulcrum, and oil cylinder can be positioned and fixed accurately and stably, to meet some oil cylinders with installation mode difficult to determine.

[0006] The utility model will be described in detail below with reference to the drawings of specification. DRAWINGS

[0022] Figure 1 is a schematic view of a support assembly structure. Figure 5The radial dimension and axial dimension of the stepped hole on the inner hole of the flange assembly are precisely matched with the annular groove of the cylinder with annular groove, so that they can be precisely positioned with each other and will not be obviously dislocated and damaged after being stressed.

[0023] The drawings attached in the specification Figure 3 The radial dimension and axial dimension of the stepped hole on the inner hole of the hinge shaft assembly are precisely matched with the annular groove of the cylinder with annular groove, so that they can be precisely positioned with each other and will not be obviously dislocated and damaged after being stressed.

[0024] The drawings attached in the specification Figure 4 The radial dimension and axial dimension of the stepped hole on the inner hole of the support assembly are precisely matched with the annular groove of the cylinder with annular groove, so that they can be precisely positioned with each other and will not be obviously dislocated and damaged after being stressed.

[0025] The working process of the cylinder with annular groove is as follows: the cylinder with annular groove is clamped and fixed on the machine by the flange assembly, the hinge shaft assembly or the support assembly, the hydraulic pressure oil enters the oil inlet of the rodless cavity, the piston and the piston assembly are pushed forward, the hydraulic pressure oil enters the oil inlet of the rod cavity, the piston and the piston assembly are retracted into the cylinder, the piston and the piston assembly return to the initial position, and the cycle is repeated. The cylinder with annular groove is reasonable in design, compact in structure and convenient to operate and use.
