In the assembly apparatus 1 according to the present invention, as shown in FIG. 5, the turntable 3 and the turntable stop plate 4 are intermittently rotated by one step of 36 ° by the driving device 100 provided as shown in FIG. (30) the first operating portion (①③⑤⑦⑨ process) and the second pinion engaging portion (40), the second operating portion (⑥⑧⑩②④ process) are alternately repeated.

First, the operation unit (①③⑤⑦⑨ process) of the pinion coupling unit 30 will be described. The first operating part is a process of coupling the shaft 21 and the pinion 22 and is operated according to the process of ① → ③ → ⑤ → ⑦ → ⑨.

(1) The process is a process of feeding the shaft 21 from the part feeder 31 to the mounting block 9 and placing the shaft 21 in series with the part feeder 31 having a conventional vacuum device. Each time 3) rotates by one step (36 °) is supplied to the mounting block (9) intermittently one by one, and the part feeder 32 is a publicly known device, so a detailed description of the operation relationship will be omitted.

After the shaft 21 is supplied from the part feeder 31 to the mounting block 9, the driving device 10 and the locking device 6 are operated.

The locking device 6 has the cylinder 11 in a state in which the locking is released from the stop groove 5 or the locking bush 3-2 as the locking pin 58-1 of the cylinder 58 is retracted and the locking is released. When the rod 12 is operated and the rod 12 is introduced, the operation plate 13 is supported by the guide pin 19 and moved to the right, and the pinion gear 8 engaged with the rack gear 14 while the operation plate 13 is moved. At this time, the turntable 3 is rotated by 36 ° and stopped, and at the same time, the locking device 6 is operated so that the locking pin 58-1 of the cylinder 58 moves to the stop groove 5 or the locking bush 3-2. ), The turntable (3) is detained and the cylinder (11) is operated in reverse and the operating plate (13) is advanced. At this time, the operating plate (13) is retracted by 실린더 θ by the cylinder (16). The rack gear 14 is operated without interference of the pinion gear 8 and the cylinder 16 is operated reversely so that the rack gear 14 of the operation plate 13 is engaged with the pinion gear 8.

When the turntable 3 is rotated by one step 36 °, the mounting block 9 in which the shaft 21 is placed in the part feeder 31 is moved to the position of the staking device 44 or the staking device 44 ) Is the second operating portion of the toothed pinion coupling portion 40, so the staking device 44 is not operated, which is not activated because nothing of the sensor 42 of the second operating portion is detected. In this state, when the driving device 10 and the locking device 6 are operated to rotate the turntable 3 by one step (36 °), the sensor 32 moves the shaft 21 installed in the mounting block 9. It detects and allows the next part feeder 33, the staking device 34, and the unloading unit to operate.

The turntable 3 is rotated one more step by the driving device 10 and the locking device 6 so as to be located in the unloading unit 45, but the unloading unit 45 is not operated because it is the second operating part. .

After a while, the driving device 10 and the locking device 6 are operated so that the turntable 3 is rotated one more step, and the mounting block 9 with the shaft 21 is loaded with the loading unit 33-of the part feeder 33. 1) is moved to the side, in which the pinion 22 is supplied from the part feeder 33, one of which is placed in the mounting block (9).

The operating rod 62 is pushed down by the cylinder 61 while compressing the spring 64 by the cylinder 61 and the mounting block 9 by the staking rod 63. By pressing the pinion 22 in the pinion pin 22 is inserted into the shaft 21 is the pinion assembly 23.

When the air pressure is removed from the cylinder 61, since the operating rod 62 is raised by the elastic force of the spring 64, the staking rod 63 is also raised.

Then, the turntable 3 is rotated one more step so that the mounting block 9 having the pinion assembly 23 is positioned on the sensor 42. However, the sensor 42 is not operated because it is a sensor of the second operating part. If the turntable 3 is rotated one more step, the mounting block 9 with the pinion assembly 23 is located in the unloading unit 35.

As shown in FIGS. 3 and 4, the unloading unit 35 has the cylinder 65 with its rod 64-1 being drawn out by the operation of the cylinder 64 with the finger 66 extended. As the cylinder 65 is operated, the finger 66 grips the shaft 21 of the pinion assembly 23. In this state, the cylinder 64 is operated to raise the cylinder 65 which has been downward, so that the pinion assembly 23 held by the finger 66 is drawn out of the mounting block 9, and the cylinder 62 is operated to Since the rod 62-1 is recovered, the operation piece 63 is moved toward the support block 61-2 along the guide rod 61-2.

Also supply pinion assembly 23 to.

When the turntable 3 is rotated one step further to operate the first operating portion (① ③ ⑤ ⑦ ⑨ process) of the pinion coupling portion 30, and the turntable 3 is rotated one step, the pinion assembly is rotated by the part feeder 43. The gear 24 is supplied to the mounting block 9-1 on which the 23 is placed, and the sensor 42 and the part feeder 41 are also activated to sense or supply a new pinion assembly 23.

After the turntable 3 is rotated one more step, the first operating part (①③⑤⑦⑨ process) of the pinion coupling part 30 is operated, and then, when the turntable 3 is rotated one more step, the staking device 44 is connected to the pinion assembly ( 23, the gear 24 is staked to form the toothed pinion assembly 26, and the part feeder 43, the sensor 42, and the part feeder 41 are simultaneously operated.

Since the staking device 44 operates in the same manner as the staking device 34 of the first operation unit, a detailed description thereof will be omitted.

When the turntable 3 is rotated by one step to operate the first operating portion (① ③ ⑤ ⑦ ⑨ process) of the pinion coupling portion 30, and the turntable 3 is rotated one more step, the staking device 44 The kingpin toothed coupling body 20 is discharged to the outside by the unloading unit 45.

Since the unloading unit 45 also operates in the same way as the unloading unit 35 of the first operating part, a description of a more specific operation relationship will be omitted.

However, the toothed pinion assembly 20 drawn out by the unloading unit 45 is transferred to the next process by a separate transfer means.
