Abstract

The utility model discloses a piston installation tool for a piston rod of a hydraulic oil cylinder, and the installation tool is a smooth and thin sleeve. It is processed from the remaining material of the cylinder barrel. The utility model has simple structure, is easy to process, and is convenient to use. It simplifies and solves the problem that the piston sealing ring is easily scratched by the thread of the hydraulic cylinder cylinder during the process of putting the piston rod of the piston machine into the cylinder cylinder of the hydraulic cylinder.

Description

Piston Installation Tool for Hydraulic Cylinder Rod

technical field

The utility model relates to a hydraulic oil cylinder installation tool. the

Background technique

At present, the general hydraulic cylinders are installed directly, which increases the risk of scratching the sealing ring on the piston and reduces the life of the sealing ring. In addition, some use other installation tools, but most of them are more cumbersome, which increases the time required for assembly. The effect Not very good. the

Contents of the invention

The purpose of this utility model is to provide a piston installation tool for the piston rod of the hydraulic cylinder, which can effectively solve the problem that the piston sealing ring of the hydraulic cylinder is scratched during the installation process, reduce the difficulty of assembling the hydraulic cylinder, and reduce the assembly preparation time at the same time. High efficiency and simple structure. the

The technical scheme of the utility model is: a piston installation tool for a piston rod of a hydraulic oil cylinder, which is characterized in that the installation tool is a smooth and thin sleeve. the

There is a handle at one end of the sleeve, and the handle is hollow cylindrical. the

The inner mouth end of the handle is in an inverted figure-eight shape. the

The sleeve is divided into two parts, namely a left sleeve and a right sleeve. the

The internal diameter of the two parts of the left sleeve and the right sleeve is identical to the internal diameter of the hydraulic cylinder. the

Beneficial effect

Due to the use of the sleeve, the problem that the piston sealing ring of the hydraulic cylinder is scratched during the installation process can be effectively solved, and at the same time, the difficulty of assembling the hydraulic cylinder is reduced, and the installation efficiency is high and the structure is simple.

Detailed ways

As shown in Figures 1 to 2, the piston installation tool for the piston rod of the hydraulic cylinder is a sleeve structure, the sleeve is a hollow cylindrical structure, and the sleeve is provided with a cylinder wall. One end of the tube wall is provided with a hand-continuing part, the tube wall is a smooth and thin-walled structure, the handle part has a certain thickness, and the inner mouth end of the handle part is in an inverted splayed shape. The sleeve is divided into two parts, respectively a left sleeve 4 and a right sleeve 5 . The internal diameter of the two parts of the left sleeve and the right sleeve is identical to the internal diameter of the hydraulic cylinder. the

The specific installation process of the utility model is as follows:

It consists of left and right parts. Assemble the piston rod (1), piston (3), hydraulic cylinder barrel (6) and rear end cover (7) first, and the front end cover (2) of the oil cylinder can be installed on the piston rod (1) first, or can be installed last For installation, lubricate the two parts of the left sleeve (5) and the right sleeve (4), and respectively protect them on both sides of the cylinder barrel (6) of the hydraulic cylinder. At this time, the piston (3) can be easily put into the cylinder barrel (6) of the hydraulic cylinder. As the piston (3) gradually sinks, the two parts of the left sleeve (5) and the right sleeve (4) return to the vertical position. Straight state, consistent with the cylinder barrel (6) of the hydraulic cylinder, and the piston (3) can be smoothly installed.

The utility model is not limited to the above-mentioned embodiment, anyone can draw other various forms of products under the enlightenment of the utility model, but no matter make any changes or improvements in the form or structure, all those with the same features as the application Or similar technical schemes all fall within the protection scope of the present utility model. the
