Further, a pair of annular springs S and S are engaged with the key K, and the spring S is attached to the key K so that the unloaded state shown by the solid line in FIG. Elastically deformed as shown by, and as a result,
The key K is pressed against the sleeve C by the elastic restoring force of the spring S, whereby the sleeve C and the hub C are pressed.
Held in place.

In the following, the operation mode of the above-mentioned annular spring assembling apparatus 1 will be described step by step with reference to FIGS. 35 to 41. First, the hub H as a work is assembled to the sleeve C, and the opening ha on one end side of the hub H is directed downward as shown in FIG.
The hub H and the sleeve C are set on the work holder 3 in a posture in which the is directed upward.

At this time, the sleeve C is accommodated in the annular rib 3b of the work holder 3 to position the center of the hub H, and the mounting portion 3a positions the hub H in the height direction. The guide protrusion 13 of the work spring guide 13 is provided in the key receiving recess Hb of the hub H.
When c is fitted, the hub H is positioned around the axis.

On the other hand, the one end side spring supply means 6 is operated to feed the spring S into the one end side spring holder 10 in the one end side mounting means 4 as described above, and the other end side spring supply means 7 is operated to operate as described above. As described above, the spring S is fed to the other end side spring holder 21 in the other end side mounting means 5.

The order of steps involved in setting the hub H and the sleeve C on the work holder 3, setting the spring S on the one end side spring holder 10, and setting the spring S on the other end side spring holder 21 is as follows. It is not specified at all and can be set arbitrarily.

Next, the other end side spring pusher 20 and the other end side spring holder 21 are moved from the retracted position shown in FIGS. 4 and 5 by the actuator 23 (see FIGS. 4 and 5) of the other end side mounting means 5. As shown in FIG. 36, the bottom of the peripheral wall 21a of the other end side spring holder 21 is lowered to an operating position where it abuts on the hub H, and the hub H is pressed and fixed to the work holder 3.

After that, the key supply hose 28 and the guide grooves 21c and 20b are fed from a parts feeder (not shown).
The key K is fed into the key-housing recess Hb of the hub H as shown in FIG. At this time, the key K is the work
The key K is positioned in the height direction with respect to the hub H and the sleeve C by placing the spring K on the guide protrusion 13c of the spring guide 13.

As shown in FIG. 37, after the key K is supplied to the hub H, the actuator 12 of the mounting means 4 on one end side is provided.
As shown in FIG. 38, when the spring pusher 11 on the one end side is moved upwards (see FIGS. 35 and 36), the spring S is compressed by the guide slope 13b of the work spring guide 13 while its outer diameter is being compressed. It is pushed up by the side spring pushers 11.

After this, one end side spring pusher 11
Is further raised, the work.
The spring S is disengaged from the spring guide 13, whereby the spring S is inserted into the opening ha at one end of the hub H, and is attached to the key K by expanding its diameter by its elastic restoring force. .

After the spring S is disengaged from the work spring guide 13, when the spring pusher 11 on the one end side is further moved upward, the spring pusher 11 on the one end side contacts the hub H as shown in FIG. When the pusher 11 is further moved upward, the hub H is pushed up as shown in FIG. 41, so that the other end side spring holder 21 in contact with the hub H is moved upward against the biasing force of the compression spring 26. It will move.

As the other end side spring holder 21 moves upward, the other end side spring pusher 20 stationary at the operating position moves downward relative to the other end side spring holder 21. As a result, the spring S housed in the other end side spring holder 21 is pushed out by the other end side spring pusher 20, and as a result, the spring S is inserted into the opening hb on the other end side of the hub H and The key is attached to the key K by enlarging the diameter by the elastic restoring force of.

As described above, the spring S for the opening ha on the one end side and the opening hb on the other end side of the hub H.
When the mounting is completed, the one end side spring pusher 11 of the one end side mounting means 4 is lowered to the initial position, and the other end side spring pusher 20 and the other end side spring holder 21 of the other end side mounting means 5 are set to the standby position. Then, the hub H and the sleeve C may be taken out from the work holder 3.

In the above-described embodiment, an example in which the present invention is applied to a device for assembling the synchronizer spring in the synchronizer manufacturing line has been shown. However, the present invention shows that the synchronizer hub as the work is provided with the synchronizer spring as the annular spring. Not only the device for attaching the work, but also various works having openings on one end side and the other end side, respectively, and the inner peripheral area of the opening on the one end side of the work and the inside of the opening on the other end side of the work. It goes without saying that the present invention can be effectively applied as a device for mounting various springs each having an annular shape in the peripheral region.

Further, in the above-described embodiment, the synchronizer sleeve accommodating the synchronizer hub is set in the work holder so that the hub as a work is movably supported by the work holder via the sleeve. However, it is needless to say that the work is directly supported by the work holder so as to be movable in a device in which the work of the hub of the synchronizer is not the work target.

[0043]

As described above in detail, in the annular spring assembling apparatus according to the present invention, the annular holder is arranged so as to face the opening on the one end side of the workpiece and the workpiece holder that supports the workpiece so as to be movable along the central axis. One end side spring holder for accommodating and holding the spring, and one end side spring pusher for moving the annular spring in the one end side spring holder to be inserted into the opening on one end side of the work and for moving the work toward the other end side A side mounting means, and a second end side spring holder for accommodating and holding an annular spring so as to face the opening on the other end side of the work and moved along with the movement of the work by the one end side spring pusher, and the other end side By moving the spring holder, the annular spring in the spring holder on the other end is pushed out It is provided and the other end side mounting means having the other end side spring pusher which is inserted into the opening end side. According to the above configuration, based on the operation of the one end side spring pusher in the one end side mounting means, the annular spring in the one end side spring holder is inserted into the one end side opening of the work, and further based on the operation of the one end side spring pusher. As the work is moved, the annular spring in the other end side spring holder of the other end side mounting means is inserted into the other end side opening of the work. As a result, according to the annular spring assembling device of the present invention, the work of mounting the annular spring on the work can be performed very easily.
