Claims

[Scope of utility model registration request]

A C-ring assembling device for assembling a C-ring into an annular ring groove formed on the inner circumferential surface of a workpiece, the taper being capable of guiding the C-ring in its axial direction while reducing its diameter. a substantially cylindrical jig having a shaped inner peripheral surface and an inner diameter dimension on the small diameter side thereof being substantially the same as the inner diameter dimension of the workpiece; a pressing member that can enter with a pressing force; and a pressing surface that is attached to the pressing member so as to be freely protrusive and retractable in the radial direction and whose tip can come into contact with the axial side surface of the C-ring. and a diameter expanding mechanism which is attached to the pressing member so as to be freely protrusive and retractable in the radial direction thereof and whose tip end is a pressing surface that can come into contact with the inner circumferential surface of the C-ring, The jig is provided with a jig that engages the pressing mechanism as the pressing member advances, and causes the pressing surface of the pressing mechanism to constantly come into contact with a predetermined position on the side surface of the C-ring. A first cam surface that moves in and out of the tool in the radial direction engages with the diameter expanding mechanism as the pressure member moves in and out, and the C ring corresponds to the ring groove so that the pressing surface of the diameter expanding mechanism and a second cam surface diameter that displaces the diameter expansion mechanism in the radial direction of the jig so that the pressing surface of the diameter expansion mechanism comes into contact with the inner circumferential surface of the C ring when the diameter expansion mechanism reaches the position where A C-ring assembly device characterized by:
