Fluid is supplied to the cylinder bore 70 of the shift ram 50 through the extension-side fluid supply passage 73a on the first side, as shown in FIG.
As shown in (c), when the piston rod 71 moves upward, the upper end surface of the insertion rod 76 is brought into contact with one end surface of the gear shaft W in a state where their axial centers are aligned with each other.

When the upward movement of the oil seal press-fitting piston rod 71 progresses further from this state, the piston rod 71 moves upward relative to the insertion rod 76, and the upper end surface of the piston rod 71 is By pressing the oil seal OS locked to the insertion rod 76, the oil seal OS is moved upward with respect to the insertion rod 76. At this time, the oil seal OS is expanded when it is locked by the shaft portion 76a of the insertion rod 76, and the inner diameter of the center hole thereof is larger than the outer diameter of the gear shaft W. When the upper end surface of the seal press-fitting piston rod 71 comes into contact with the peripheral wall RW of the front case FC, it is mounted between the peripheral wall RW and the outer peripheral surface of the gear shaft W.

When the oil seal OS is fitted on the gear shaft W, the clamper (not shown) is released, and after the above-mentioned transfer pallet MP is transferred to the equipment of the next process, the circlip and the oil are transferred to the gear shaft. In order to mount the seal, a new transport pallet is installed on the plane D along the center axis of the gear shaft.
It is positioned and installed in a state that conforms to.

During this time, fluid is supplied to the cylinder bore 70 of the shift ram 50 through the compression-side fluid supply passage 72a on the oil seal press-fitting piston rod 71 side, and the shift cylinder actuator 4 is also supplied.
0 is retracted, and the piston rod 71 and the shift ram 50 are respectively returned to the above-mentioned start standby state.

Hereinafter, the above-described operation is sequentially repeated, and the circlip and the oil seal are mounted on the gear shaft.

In the above embodiment, the mounting device applied when mounting the circlip and the oil seal on the gear shaft is shown as an example. However, the present invention is not limited to these, and other devices than the gear shaft are used. The present invention can of course be applied to the case where an elastic ring-shaped member other than the circlip and the oil seal is attached to the work. Further, the mounting device for mounting the elastic ring-shaped member on the outer peripheral surface of the work is illustrated. However, if the tapered portion and the locking portion are provided on the inner peripheral surface of the holding member, respectively, they are mounted on the inner peripheral surface of the work. The elastic ring-shaped member can be applied to the device.

Further, in the above embodiment, the retaining member is formed with the engaging portion, but this engaging portion is not always necessary. In the case where the retaining member is provided with the retaining portion, in the embodiment, the cylindrical portion, that is, the retaining portion having the inclination of 0 is illustrated, but the inclination of the retaining portion is not necessarily 0. Further, a locking portion having a negative inclination, that is, a locking portion inclined in the opposite direction to the tapered portion may be formed.

[0056]

As described above, according to the elastic ring-shaped member mounting device of the present invention, the elastic ring-shaped member supplied to the receiving position by moving the holding member having the tapered portion is moved. Since the elastic ring-shaped member is conveyed to the mounting position and the elastic ring-shaped member held by the holding member is fitted into the fitting groove of the work as it is, the elastic ring-shaped member is held during the conveyance or the elastic ring is conveyed. A mechanism for inserting and arranging the ring-shaped member into the taper-shaped member is unnecessary, and it is possible to suppress the complication of the structure and the increase in cost as much as possible while facilitating the mounting work of the elastic ring member. .
