Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for mounting a flexible cap such as a rubber cap on a small-diameter round bar made of metal.

[0002]

2. Description of the Related Art Conventionally, in order to attach a rubber cap to a small-diameter round rod made of metal, as shown in FIG. 21, a rubber cap 1 and a small-diameter round rod 2 are respectively held by hand and attached by hand. Was.

[0003]

However, since such work is a simple work in which fine parts are covered by hand, work efficiency is poor and a heavy load is placed on a person.

In addition, when the surface of the small-diameter round rod to which the cap is mounted is coated with a coating layer such as soft plating or coating, when the fixing or positioning is performed on the device because the coating layer is soft, If it was strongly rubbed or scratched, it could be scratched or peeled off.

Further, when the cap is made of rubber, it is easily deformed when a force is applied, the small-diameter round bar and the cap are not aligned with each other, and the cap insertion hole is also deformed, which makes it difficult to enter. In order to prevent this, it is thought that the work will be easier if the cap is fixed to either a round bar, but when the cap is flexible, it is difficult to fix it to a fixing device, for example, a chuck, Moreover, the position of the cap was unstable and the round bar often did not enter, making the work extremely difficult. Also, as for the small-diameter round bar, it is difficult to fix it to the chuck or the like at the correct position as described above because of its small diameter.

Therefore, it is difficult to develop a device in which a cap or a small-diameter round bar is mounted, and conventionally, the only method is to cover the small-diameter round bar by hand.
Therefore, as mentioned above, it is inefficient and leads to cost increase.

Therefore, a technical object of the present invention is to provide a cap mounting device for a small-diameter round bar, which can easily and efficiently mount a flexible cap on the small-diameter round bar.
