Abstract

In a flexible ring fitting device 1 , a flexible ring disposition mechanism includes at least two ring support members 411 and 412 disposed relative to each other and movable so as to be separated from each other. Notches 4113 and 4123 recessed in a direction in which the two ring support members 411 and 412 are separated from each other are formed along surfaces 4114 and 4124 of the two relative ring support members 411 and 412 in the relative surfaces 4114 and 4124 of the two ring support members 411 and 412 . A flexible ring R is fitted into an annular groove G of a workpiece W by a workpiece disposition mechanism moving in one direction along with the workpiece W.

First claim

What is claimed is:

1. A flexible ring fitting device fitting a flexible ring into an annular groove of a workpiece having the annular groove in an outer periphery of the workpiece, the flexible ring fitting device comprising:
a workpiece placement table adapted to have the workpiece disposed thereon such that the groove of the workpiece and the flexible ring are relative to each other; and
a flexible ring disposition mechanism installed adjacent to the workpiece disposition mechanism, wherein
the workpiece placement table is movable in two directions, wherein the two directions comprise a first direction and a second direction, the second direction being opposite to the first direction,
the flexible ring disposition mechanism includes at least two ring support members and notches formed along surfaces of the at least two ring support members, wherein the at least two ring support members are disposed relative to each other and are movable so as to be separated from each other, and the notches are recessed in a direction in which the at least two ring support members are movable to be separated from each other and are formed along relative surfaces of the at least two ring support members, and
the flexible ring is fitted into the annular groove of the workpiece by the workpiece placement table moving in the first direction along with the workpiece.

2. The flexible ring fitting device according to claim 1 , wherein the workpiece placement table includes a disposition surface for placing the workpiece, the flexible ring disposition mechanism includes a flexible ring disposition surface for placing the flexible ring, and the disposition surface of the workpiece placement table is provided such that the workpiece placed thereon is at a position further from the flexible ring disposition surface in the second direction than a thickness of the flexible ring.

3. The flexible ring fitting device according to claim 1 , wherein a first spring is provided on the first direction side of the workpiece placement table and the first spring presses the workpiece placement table in the second direction.

4. The flexible ring fitting device according to claim 1 , wherein a second spring is provided on a side opposite to the relative surface side of the ring support member and the second spring urges and presses the two ring support members toward each other.

5. The flexible ring fitting device according to claim 1 , wherein a depth of each of the notches has a part gradually increasing toward the workpiece disposition mechanism.

6. The flexible ring fitting device according to claim 1 , further comprising a workpiece abutting portion configured to abut against the workpiece placed on the workpiece placement table to move the workpiece placement table in the first direction.
