Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grease applying jig, and more particularly to a structure of a grease applying jig suitable for being inserted into a hole of an object having a hole and applying grease to the inside of the hole. Things.

[0002]

2. Description of the Related Art Conventionally, when applying grease inside a hole of an object such as a slide bush, for example, as shown in FIG. It was applied manually by inserting it inside.

[0003]

However, when grease is applied by hand using the elongated rod 1 as described above,
Since it was a manual operation, it took a very long time to complete the application. Further, it is difficult to uniformly apply the grease 2 to the inside of the slide bush 3, and particularly, it is very difficult to apply the grease 2 to the inside of the slide bush 3.

Further, in some cases, the grease 2 is applied to an operator's hand or finger when the grease 2 is applied to the elongated rod 1.
There is also a problem that the toner adheres and becomes dirty, which makes the operator uncomfortable. In such a state where the worker is uncomfortable with the work, there is no hope of improving the work efficiency.

[0005]

In order to solve the above-mentioned problems, the present invention provides a method of applying grease to the inside of a hole of an object, which has an outer shape corresponding to the inner shape of the object, A jig having a hollow body having a grease inlet and a plurality of holes for applying grease is used. Then, the jig is inserted into the hole of the object, and grease is injected by applying sufficient pressure into the body of the jig through the grease injection port of the jig. The grease is supplied uniformly from the hole into the hole of the object.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to a grease applying jig for inserting and using grease inside a hole of an object when applying grease inside the hole of the object. The body includes a hollow body having an outer shape corresponding to the internal shape, a grease inlet provided at one end of the body, and a plurality of holes provided on side surfaces of the body.

Here, the outer shape of the body corresponds to the internal shape of the hole in the object. In other words, the internal shape of the hole in the object
For example, in the case of a cylindrical shape, the outer shape of the body of the grease applying jig of the present invention is also formed in a cylindrical shape, and when the internal shape of the hole of the object is a rectangular parallelepiped, the outer shape of the body is also It is formed in a rectangular parallelepiped shape. In addition to these,
For example, various shapes can be considered as the outer shape of the body depending on the internal shape of the object, such as a conical shape, but in any case, the grease application jig of the present invention is used by inserting it into the object. Therefore, the outer diameter of the body is set smaller than the inner diameter of the hole of the object.

Further, a plurality of holes are formed in the side surface of the body. When grease is applied to the side and bottom surfaces of the object, holes may be formed in the bottom surface of the other end of the grease injection port forming surface of the body. Here, the location of the hole on the side surface of the body is set according to the depth of the hole of the object.
That is, the hole is formed in a range that is not exposed to the outside of the hole of the object when the body is inserted into the hole of the object. This is because if the hole is formed by exposing the outside of the hole of the object, the grease is injected with sufficient pressure inside the body,
Grease leaked out from this exposed hole,
This is because the jig and the surroundings are contaminated with grease. The size and the number of holes can be appropriately selected as long as the flow of the grease is not impaired, and the shape of the holes can be freely set such as a circle, a square, a triangle, and a star.

The grease injection port of the grease application jig may be provided with a connection portion for connecting to a tip of the injection port of a grease injector such as a grease gun. This connection portion may be formed detachably using, for example, a nipple.

[0010] A stopper may be attached to the outside of the body. The outer diameter of the stopper is formed to be at least larger than the inner diameter of the hole of the object. In this case, the position of the stopper is determined by the depth of the hole in the object.
That is, when the body is inserted into the hole of the object, the position of the stopper is determined by limiting the extent to which the bottom surface of the body contacts the bottom of the hole of the object. Here, since the outer diameter of the stopper is formed at least larger than the inner diameter of the hole of the object, when the body is inserted into the hole of the object, the stopper is caught on the edge of the hole of the object. It serves to support the torso so that the torso does not fall into the hole. Further, the stopper also serves to prevent grease applied to the inside of the hole of the object from flowing backward and leaking out of the hole.

Further, the stopper may be movable. In this way, there is an advantage that the same jig can be used even when the different objects have substantially the same internal shape and inner diameter and differ only in the depth.

More preferably, the stopper is formed wide. Even if the stopper is movable as described above, when the depth of the object is greatly different, for example, the jig of the present invention is applied to an object having a hole that is extremely shallower than the depth planned at the time of manufacturing the jig. If used, the holes formed on the side of the body will accidentally be exposed outside the holes of the object, and as a result, when the grease is injected with sufficient pressure applied to the body, Grease leaks from the hole. Therefore, if the stopper is formed wide, even if the hole formed on the side surface of the body is exposed to the outside of the hole of the object due to the shallow depth of the hole of the object as described above, Since the hole is closed by the stopper, grease can be prevented from leaking.
