。The minute feed mechanism 147 is started by detecting the swinging of the yoke support member 71 by the direct switches 161 disposed on both sides of the upper part of the yoke support member 71 of the positioning and holding mechanism 49 described above. (See FIG. 8) That is, when the press-fitting punches 112 on both sides move forward and press-fit the bearings 13, 13 into the bearing holes 9, 9 on both sides of the tube yoke 2, a pressing force is applied to the spider 3 into which the bearings 13, 13 are fitted. This causes the bearings 13, 13 to become disengaged from the shafts 12a, 12a on both sides.
On the side that abuts the end surface of 2a, the pushing force of the press-fitting punch 112 is directly transmitted to the spider 3, and at this point the balance of pushing forces on both sides acting on the spider 3 is lost, so that the positioning and holding mechanism 49 The held spider 3 swings around the cross joint 68, and as a result, the yoke support member 71, which is tilted around the cross joint 68, connects the direct switch 161 located on the press-fit punch side to which the pushing force was directly transmitted. You will have to press it.

stops the press-fitting movement, and the other press-fitting cylinder 148 continues press-fitting the bearing, and when the bearing comes into contact with the end face of the shaft,
Since the pressing forces on both sides acting on the spider 3 are equal and balanced, the spider 3 returns to its original position, the yoke support member 71 returns to the center position, and the pressure on the direct switch 161 is released.

The bearing 13 is press-fitted to a completely fitted position where the end face of the bearing 13 comes into contact with the end face of the bearing 13.

ている。During minute press-fitting by the minute feed mechanism 147, the pressure acting on the load cell 146 increases when the end face of the bearing 13 comes into contact with the end face of the shaft 12a, so it is difficult to completely fit the bearing 13 onto the shaft 12a. It can be detected electrically, so that the load cell 146 will stop the micro feed mechanism 147 when it detects complete engagement.

The bearing 13 is press-fitted into the shaft 12a, and its end surface is pressed into the shaft 12a.
It is securely fitted to the position where it abuts the end face of a. (Figure 1
3) Subsequently, the caulking punch 113 moves forward under low pressure by the operation of the low-pressure cylinder 145, and when it stops with its tip in contact with the end surface of the yoke portion 8, the relative positions of the press-fit punch 112 and the caulking punch 113 are detected by the detection mechanism 162. The caulking amount adjusting member 163 is detected based on the detected value.
is activated, and the amount of caulking is set in accordance with the dimension from the outer end surface of the bearing 13 to the outer end surface of the yoke portion 8. (See Fig. 14) Next, the caulking punch 1 is activated by the operation of the high pressure cylinder 143.
13 is advanced under high pressure and its tip enters toward the bearing hole 9, thereby forming a caulked portion 14 around the bearing hole 9. The amount of crimp movement of the crimp punch 113 is determined by the crimp adjustment member 1
63, it is possible to accurately form the caulked portion 14 in the amount required to prevent the bearing 13 from coming off. (See Figure 15) When the crimping is completed, the press-fitting punch 11
2 and the caulking punch 113 move back, the expansion claw 111 releases the expansion of the yoke parts 8, 8, the table 44 returns to the supply/discharge alignment position A, and the assembled body is pushed out by the pusher 90 onto the mounting table 86. It is taken out, and the assembly of the tube yoke 2 and spider 3 is completed.

てを実現できる。[Effects] As described above, according to the present invention, the flange yoke or sleeve yoke with the spider assembled in advance is supported in a floating state, and the positioning of the upper and lower bearing holes of the flange yoke or sleeve yoke and the centering of the spider shaft are performed. Since both yokes are fixed while floating, positioning and alignment of the bearing hole of the flange yoke or sleeve yoke and the spider shaft can be easily and accurately performed, and the tube inserted into the spider shaft can be easily and accurately positioned. Press fitting of the bearing into the bearing hole of the yoke and formation of the caulked portion can be performed continuously, and automatic assembly of a Cardan joint using a flange yoke or a sleeve yoke and a tube yoke can be realized.
