Description

Cylinder spring removal tool

Technical field:

The utility model relates to a tool for disassembling and assembling the cylinder body spring of a through-shaft axial plunger pump.

Background technique:

When repairing the through-shaft axial piston pump, it is a difficult problem to disassemble and install the cylinder spring. The elastic force of the compression spring is strong. To remove the spring, the gasket should be pushed in to the right first, and then the retaining ring for the hole should be removed with the circlip pliers, and then the gasket can be withdrawn slowly, and the spring can be removed. When installing the spring, use the reverse procedure. At present, dismounting and assembling this spring requires two people to cooperate on the vise. This dismounting method is not only laborious but also inconvenient and not safe.

Invention content:

The purpose of the utility model is to provide a cylinder spring dismounting tool, which can safely and conveniently disassemble and install the cylinder spring by one person.

In order to achieve the above object, the utility model adopts the following technical solutions:

The utility model comprises a pull rod. One end of the pull rod is provided with a pull head, and the other end is provided with a threaded head and matching nuts and washers.

The utility model has the characteristics of simple structure, convenient use and the like.

5. Nut 6. Washer 7. Pull rod 8. Pull head 9. Thread head

Detailed ways:

As can be seen from Fig. 1, the utility model includes a pull rod 7, one end of the pull rod 7 is provided with a pull head 8, the pull head 8 is convex, and the other end is provided with a threaded head 9 and a nut 5 and a washer 6 for matching use thereof.

As can be seen from Fig. 2, the working principle of the utility model is as follows: the pull rod 7 is penetrated from the inner hole of the cylinder body 3, the pull head of the pull rod is pressed on the gasket 2, the washer 6 is put on the thread head, and the nut 5 is screwed in , and then use a wrench to rotate the nut 5 clockwise, so that the pull rod passes through the gasket 2 to compress the spring 4. After the slider leaves the retaining ring 1, use the circlip pliers to remove the retaining ring, and then reverse the nut 5, the spring can be disassembled , When installing the spring, it can be installed by the opposite method of removing it.
