The present invention is a starter motor armature for intermittently rotating the armature by a certain angle to insert or caulk a coil in the slot of the armature formed in a plurality of predetermined angles at the time of manufacturing the starter motor armature (Armature) The present invention relates to a manufacturing indexing device, and to an indexing device for manufacturing a starter motor armature, which can be easily used interchangeably even when the number of slots of the armatures is different, without having to replace a gear or the like that is a drive transmission means. In general, the armature manufacturing process of the starter motor is a process of manufacturing a plurality of slots iron cores formed in a plurality of radial directions at regular angle intervals, and the iron core produced in the process is rotated by the drive motor (7) as shown in FIG. For the armature manufacturing consisting of the first gear (2) and the second gear (3) connected in the middle to transfer the index (1) to the intermittent movement and the rotational force of the index to the support (4) of the iron core (5) By the indexing device, the iron core 5 is intermittently rotated at an angle equal to the slot interval, thereby inserting or caulking the coil 6 into the slot, thereby completing the manufacture of the armature.

In the above-described latter process, for example, in order to manufacture an armature having 21 slots, the iron core 5 must be rotated 1/21 per rotation of the index 1 (because between slots Angle = 1/21 × 360 °), and the reduction ratio at the first gear 2 and the second gear 3 should be 8/21 when the reduction ratio in the index 1 is 1/8 (because the final When the reduction ratio (1/21) = index reduction ratio (1/8) x gear reduction ratio (8/21) and the size of the first gear 2 are 32, the size of the second gear 3 is 84.

By the way, in the conventional index 1 described above, when an armature having a different number of slots is produced, that is, when the armature having 29 slots is manufactured, it is impossible to change the rotation speed of the index 1, The gear ratio of the first gear 2 and the second gear 3 should be changed to be 8/29. That is, the first gear 2 has 32 dimensions but the second gear 3 is used as it is. It has 116 dimensions and needs to be changed.

Therefore, the above-described conventional apparatus is almost impossible to use interchangeably in the manufacture of armatures with different slots, and thus requires a large number of models, which may cause an increase in the manufacturing cost of the armature and occupy a large area of the workplace. There was a problem.

In order to solve the above problems, in the present invention, while maintaining the reduction ratio in the first gear and the second gear as the power transmission means, the rotational speed is changed according to the number of slots of the armature to be manufactured at the index for transmitting the rotational force to the gear. In order to be possible to generate differently, the object of the present invention is to enable the manufacture of various types of armatures having different slot numbers without changing and using the first gear and the second gear. The first and second gears can be easily changed for the rotational angular speed of the motor by attaching a rotary encoder to the shaft of the motor while enabling the intermittent rotational movement of the drive motor using a stepping motor. It is possible to manufacture various types of armatures without modification.

When described in detail with the accompanying drawings as follows.

As shown in FIG. 1, the index 1 rotates by the driving motor 7 and intermittently moves, and the rotational force of the index supports the core 5 of which a plurality of slots are formed in a plurality of radial directions at regular angle intervals. 1. An armature manufacturing indexing device comprising a first gear (2) and a second gear (3) connected between the support (4) and the index (1) for delivery to the earth (4); A stepping motor is used to intermittently rotate the driving motor 7 which generates the rotational force to the index 1 by one rotation, and is input to the shaft 11 of the motor by a separate input means (not shown). A rotary encoder 8 is attached to control the rotational angular velocity of the shaft 11 at the angular velocity value.

In addition, in the rotary encoder 8, a slit plate 10 in which a plurality of slits are perforated is constructed in order to generate a pulse signal by the optical sensor 9.

Referring to the operation and effects of the device of the present invention configured as described above are as follows.

The first gear 2 has 32 dimensions, the second gear 3 has 84 dimensions, and the reduction ratio of the index 1 is 1/8. For example, the final reduction ratio is 32/84 (gear reduction ratio). ) X 1/8 (index reduction ratio) = 1/21, where the drive motor that is a stepping motor in the rotary encoder is set so that the rotation angle of the iron core 5 per revolution of the index (1) is 1/21 × 360 °. By setting the standard intermittent rotational angular velocity of (7), it is possible to manufacture an armature having 21 slots continuously.

However, in this case, it is possible to slow down the intermittent rotational angular speed of the drive motor 7 by 21/29 in the above state to manufacture an armature having 29 slots (21/29 (final reduction ratio) = 32/84 (gear reduction ratio)). X 1/8 (index reduction ratio) x 21/29 (rotational correction value)), that is, the rotational angular velocity multiplied by the rotational correction value 21/29 from the rotational angular velocity of the drive motor 7 when the 21 slot armature is manufactured. If corrected by (i.e., if the rate of generation of the pulse signal generated by the optical sensor 9 when the slit plate 11 is rotated is reduced to the value multiplied by 21/29 from the initial value), the index (1) once Since the rotation angle of the permissive iron core 5 is changed to 1/29 × 360 °, an armature having 29 slots can be easily manufactured.

As described above, the apparatus of the present invention intermittently rotates the drive motor 7 by the rotary encoder 8 without having to replace the first gear 2 or the first gear 3, which is a power transmission device, even when manufacturing armatures with different slot numbers. By easily changing and setting the angular velocity, it is a useful invention that the same starter motor armature indexing apparatus can be used interchangeably.
