を有する短筒状のゴムリングが多用されている。2. Description of the Related Art Generally, when various devices are mounted on a site where vibration is generated, or when a device which generates vibration is mounted on a substrate, noise associated with the vibration is prevented, and the device is liable to be modulated or broken due to the vibration. In order to prevent looseness or damage of the connection portion, a rubber vibration isolator is often interposed at the mounting site. For example, when installing an inlet manifold, an air cleaner, a radiator, a battery, various liquid tanks, etc. by bolt connection in the engine room of an automobile, the vibration isolator has a short tubular shape with an annular fitting groove at the center position of the outer circumference. A lot of rubber rings are used.

うになっている。This anti-vibration rubber ring is forcibly press-fitted into a mounting hole of an object to be mounted so that an annular fitting groove is fitted in the mounting hole, and at the same time, large-diameter flange-shaped portions are formed. Is locked to both outer sides of the mounting hole, and is connected to the mating mounting portion via a bolt that passes through the hole of the rubber ring.

Since the operator directly pushes the rubber ring into the hole for attachment of the object to be attached with his / her finger, or uses an appropriate tool at hand to assist it,
The press-fitting operation is very time-consuming and inefficient, and the rubber ring is in an incomplete mating state, which may cause the rubber ring to fall off before it is used in the next bolt connecting process, or force correction work when connecting the bolts. There were many.

It is intended to provide a press-fitting tool for performing efficiently and reliably.

When the elastic ring 3 is press-fitted into the mounting hole 4a, the elastic ring 3 is loaded into the holding cylinder 1, and the holding cylinder 1 is held by one hand so that the one end 1a side is substantially at the mounting hole 4a position. When the press-fitting shaft portion 2a of the pressing rod 2 held concentrically with the other hand is inserted into the holding cylinder 1 from the other end 1b side and pressed, the elastic ring 3 is forced from the holding cylinder 1. Is pushed out, and the large-diameter collar-shaped portion 32a on the front side thereof passes through the mounting hole 4a in a compressed and deformed state and is restored to the original shape on the outside of the mounting hole 4a. To fit. At this time, since the short-axis projection 23 of the pressing rod 2 is disposed in the hole 30 of the elastic ring 3, the collar-shaped portion 32a of the elastic ring 3 is in a distorted deformed state when returning from the compressed state. As a result, the annular fitting groove 31 is surely fitted into the mounting hole 4a.

る。Further, according to the present invention, the pressing rod 2 has a stopper portion 25 which determines the insertion limit of the press-fitting shaft portion 2a by abutting against the other end of the holding cylinder 1. Therefore, if the position of the insertion limit of the press-fitting shaft portion 2a by the stopper portion 25 is properly set, the one end 1a side of the holding cylinder 1 loaded with the elastic ring 3 is set to the mounting hole 4a position of the mounted object 4. When pressing and pressing the pressing rod 2 inserted in the holding cylinder 1,
Since the tip of the press-fitting shaft portion 2a is stopped by the stopper portion 25 at a predetermined insertion depth, the elastic ring 3 is excessively pushed into the mounting hole 4a up to the rear flange portion 32b or the mounting hole 4a. The elastic ring 3 is surely brought into a proper fitting state without passing through and falling off.

する。In order to fit the elastic ring 3 into each mounting hole 4a of the object 4 to be mounted, first of all, as shown in FIG. Edge 1
It is loaded from the b side, and similarly, the press-fitting shaft portion 2a of the pressing rod 2 is inserted from the other end 1b side, and the short shaft-shaped projection 23 is inserted into the hole portion 30 of the elastic ring 3. Then, as shown in FIG. 3A, the holding cylinder 1 is held by one hand, the one end 1a side is applied to the position of the mounting hole 4a in a substantially concentric manner, and the pressing rod 2 held by the other hand is held. As you push in, the elastic ring 3
Is pushed by the annular step portion 24 of the pressing rod 2 and moves to the end 1a side in the center hole 10, but is gradually compressed as the inner diameter is reduced in the process of passing through the tapered hole portion 10a, and the holding cylinder 1 In the vicinity of one end 1a side, the entire outer periphery is in a compression deformation state substantially equal to the diameter of the mounting hole 4a as shown in the figure. When the pressing rod 2 is further pushed in this state, the elastic ring 3 is forcibly pushed out of the holding cylinder 1 as shown in FIG.
The large-diameter collar-shaped portion 32a on the front side thereof passes through the mounting hole 4a in a compressed and deformed state, and is restored to the original shape on the outside where the ring-shaped fitting groove 31 fits into the mounting hole 4a.

嵌着状態となっている。At this time, the elastic ring 3 is in a compression deformed state in which the entire outer periphery is approximately equal to the diameter of the mounting hole 4a in the vicinity of the one end 1a side of the holding cylinder 1, and when pushed out from the holding cylinder 1, Since the collar-shaped portion 32a on the side of the portion smoothly passes through the mounting hole 4a without being caught at the opening edge of the mounting hole 4a, damage such as cracks does not occur, and the short-axis projection of the pressing rod 2 does not occur. By arranging 23 projectingly into the hole 30 of the elastic ring 3, the collar-shaped portion 3 of the elastic ring 3 is formed.
When 2a returns from the compressed state, it does not become a distorted deformed state, so that the annular fitting groove 31 surely fits into the mounting hole 4a. When the annular fitting groove 31 is fitted in this way, the stopper portion 25 of the pressing rod 2 and the annular tapered surface 11 of the holding cylinder 1 come into contact with each other, thereby preventing further insertion of the short shaft-like projection 23. Therefore, the press-fitting operation described above is performed by the pressing rod 2.
Just push it to the limit. Then, if the entire press-fitting tool T is pulled away, the elastic ring 3 will have the collar-shaped portions 32 on both sides.
The a and 32b are arranged properly on both outer sides of the mounting projection 41.

The above-described press-fitting operation may be performed by applying it to the position of the hole 4a.

As shown in FIG. 5 , metal collars 5 and 5 including a tubular portion 5a and a collar portion 5b are fitted to the elastic ring 3 from both sides. Then, as shown in FIG. 6 , the connecting bolt 8 is passed through the hole 30 in which the collars 5 and 5 are interposed and the bolt insertion hole 7a of the mounting portion 7 on the base 6 side, and the nut 9 is screwed and tightened. As a result, the object to be attached 4 is attached to the base 6.
In such a mounting structure, the object to be mounted 4 is held on the base 6 by the elastic ring 3 interposed in the joint portion without direct metal contact, so that the base 4 can be mounted on a base such as an automobile. Even if the 6 side vibrates violently,
As a result of the vibration being absorbed by the elastic ring 3, it is possible to prevent noise associated with the vibration, modulation or failure due to the vibration of the mounted object 4 side, loosening or damage of the connection portion, and the like.

いう利点がある。As such an elastic ring press-fitting tool, in particular, as in the second aspect of the invention, one end side of the holding cylinder has a diameter substantially equal to the diameter of the attachment hole of the attachment object and the other end side. If the diameter of the elastic ring is increased and the central hole is provided with a tapered hole portion that reduces its diameter toward the one end side, it becomes easy to load the elastic ring into the holding cylinder, and at the same time, the elastic ring is pressed through the elastic rod. When the ring is pushed into the vicinity of one end side of the holding cylinder, the entire outer circumference is in a compression deformation state approximately equal to the diameter of the mounting hole, and when this elastic ring is forcibly pushed out of the holding cylinder, the collar part on the front side is formed. Since it smoothly passes through the mounting hole without getting caught, there is an advantage that damage such as cracks can be prevented.
