The claw holder 85 is rotated by 0° and returned to its original position. At this time, the sensor 110 collides with the first stopper 112 and returns to the first limit position S1 as shown in the solid line position in FIG. Senses when it returns to its position.

Next, the sleeve rotation control mechanism 72 is controlled by the drive cylinder 78.
When the whole is moved forward again, the claw portions 89 of the three claw members 89... ... enters the sleeve S without hitting the three pairs of lofty 31..., and the sleeve S changes from Fig. 15 (C) to the state shown in Fig. 14 by rotating the drive motor 82 by 180 degrees.
Rotate and attach the hub to the sleeve S as in the case described in section (A) above! (Can be fitted.

After the engagement between the sleeve S and the hub H is completed, the drive cylinder 6
When the sleeve restraining mechanism 60 and the stopper mechanism 52 are operated backward by the contraction operation of 2.53 (Fig. 4), the fitted assembly A of the sleeve S and the hub H becomes free, and then the drive cylinder 67 is extended. When activated, the sleeve thrusting mechanism 66 is moved forward to move the fitting assembly A into the inclined shoe).
13, the fitting assembly A is again transferred on the inclined chute 13 by its own weight.

At the lower part of the inclined chute 13, there are four first to fourth loading cart positions 17. according to the hub H, which is divided into four stages according to the outer diameter as described above. An assembly mounting table 17 having .about.174 is provided perpendicular to the longitudinal direction of the inclined chute 13. The first to fourth mounting table units 171 to 174 are two adjacent pedestals 129 to 133 arranged in parallel on the machine frame 15 at different heights along the inclination direction of the inclined chute 13. Two pedestals 129, 130i130゜13

are concatenated. Due to the operation of the cylinder 141, the stopper piece 143 is moved to the first mounting table unit 17. The first loading trolley moves forward and backward toward the position 17. The fitting assembly A transferred upward is restrained on the mounting table unit 171.

Stopper 13 corresponding to the fourth loading cart position 174 at the lowest end

A dispensing device 146 is provided on the side of the inclined chute 13 opposite to the assembly mounting table 17 for dispensing the assembled assembly placed on the mounting table 17. This dispensing device 1
The structure of 46 will be explained with reference to FIGS. 17(A) and 17(B). A support plate 147 is integrally extended substantially horizontally on the side opposite to 174, and a payout cylinder 149 is mounted on the support plate 147 via a vertical stay 148 to face the inclined chute 13 in the longitudinal direction. Supported.

Make it.

Now, assuming that the fitting assembly A corresponds to the 3i32 mount unit 17°, the dispensing operation of the assembly A will be explained with reference to FIG. 4 and FIGS. 17(A) and (B). To explain, in response to the selection signal of the hub H from the robot 18, the third stopper 138 of the third mounting cart position 173 is operated to extend as shown in FIG. Assembly A is placed on the third mounting table unit 17. Stop at the top. As shown in FIG. 17(A), a third bushing 151 fixed to the dispensing machine 15 (H) is attached to one side of the fitting assembly.

When the assembly A is ejected forward, the assembly A has its side facing the third
It falls onto the mounting table unit 173 while being received by the weight 135 on the mounting table unit 173. When the dispensing of the fitting assembly to the third mounting table unit 173 is completed, the dispensing device 146 returns to its original position.

Next, a procedure for selecting and fitting the sleeve S and the hub H will be explained.

(2) In FIG. 3, one of the sleeves S with a calanque reverse gear, which is a female gear placed on the conveyor rail 9, at the forefront is placed vertically on the upper part of the inclined chute 13 by an appropriate conveyance means. The sleeve S is an inclined shoe) 13
It rolls down under its own weight and reaches the inner diameter measurement position P+.

■ When the sleeve S moving on the inclined chute 13 reaches the inner diameter measurement position P, the sleeve S is stopped by the stopper device 20 and its outer peripheral surface is pressed against the rotating brush, as shown in FIGS. 4 and 5. As described above, the inner diameter of the sleeve S having internal teeth is measured by operating the inner diameter measuring position 28 while being in contact with the sleeve S and being rotated slowly by friction.

(2) When the inner diameter measurement of the sleeve S is completed, the stopper device 20 is deactivated (the stopper piece 22 is at the chain line position in FIG. 4), and the sleeve S is ejected and again rolls down onto the inclined shoe 13 to the fitting position P2. At this fitting position 1pt, the sleeve S is placed on the sleeve holding member 57 and is received by the operation of the stopper device 52.

■ When the sleeve S is placed on the holding member 57 at the fitting position P2, the robot 18 is actuated by I-kun who sends a measurement value signal obtained by measuring the inner diameter of the sleeve S to the robot robot 1-18. Figure 3) 1st to 4th stock car position 16. From the group of hubs H classified by outer diameter size in ~164, the hub H having the outer diameter most suitable for fitting with the sleeve S was taken out and brought to the hub pedestal 70, The hub H is installed on the rail member 71 by fitting the cutout recess 6 of the hub H onto the rail member 71 thereon.

- When the sleeve S is placed on the holding member 57 and the hub H is placed on the hub pedestal 70 as described above, the sleeve S is removed by the operation of the sleeve restraining mechanism 60 as shown in FIG.
is held on the holding member 57 so that it can rotate but not move in the axial direction.

Next, as described above, the internal teeth 3 of the sleeve S and the external teeth 5 of the hub H are fitted by the operation of the fitting device 69, that is, the sleeve rotation control mechanism 72 and the hub pushing mechanism 73.

- When the sleeve S and hub H are completely fitted, the sleeve restraining mechanism 60 is deactivated, the sleeve S and hub H fitting assembly A becomes free, and the sleeve lifting mechanism 66 is activated. Then, the fitting assembly A is pushed up onto the inclined chute 13 and rolls down on the inclined chute 13.

■ When the fitting assembly A rolls down to the assembly mounting table 17, the inner diameter and dimensions of the taken out hub H are sent in advance to the first to third stoppers 136 to 138, so that the fitting assembly A can be adjusted accordingly. The first to fourth stoppers (the fourth stopper 139 is of a fixed type, so it does not substantially operate) operate, and the first to fourth mounting table units 17. ~174
The fitting assembly A is received at a position corresponding to either of the above.

■Finally, the device 146 for discharging the mating assemblies 146 operates as described above to move the mating assemblies A to the first to fourth!5th! Place it on any of the stand units tL-t74. Their listing “
Unit unit 17. 174, the fitting assemblies A are placed in alignment so as not to fall down by the cooperation of the dispensing device 146 and the weight 135.

The above completes the fitting work of the female gear, that is, the sleeve S with the counter reverse gear, and the male gear, that is, the synchronizer hub H. In the above embodiment, the selection of the sleeve S with the counter reverse gear 2 and the synchronizer hub H, Although the fitting device has been described, the present invention also includes other female gears having internal teeth,
Of course, the present invention can also be applied to the selection and fitting of male gears having external teeth.

C0 Effects of the Invention As described above, according to the present invention, the female gear and the male gear are arranged on the same horizontal axis, and the male gear is controlled to rotate to the fitting position with respect to the female gear, so that both gears can be moved. Since the fitting can be performed, the female and male gears whose fitting positions have been determined can be automatically and efficiently and precisely fitted, which was conventionally done manually.
