[0018]
A method of using the rotor assembling apparatus configured as described above will be described below with reference to the drawings.
[0019]
2 to 9 are views for explaining a method of using the rotor assembling apparatus according to the embodiment of the present invention.
[0020]
First, as shown in FIG. 2, the shaft 31 is inserted into the shaft regulating shaft insertion hole 23 from the inclined portion 24 of the shaft regulating shaft insertion hole of the shaft regulating bush 22 until the shaft 31 comes into contact with the distal end 15 of the shaft regulating shaft 14.
[0021]
Next, as shown in FIG. 3, the rotary yoke 32 is placed on the tip of the upper surface of the rotor holding base 11 with the opening side of the rotary yoke 32 facing downward.
[0022]
Next, as shown in FIG. 4, a press-fit head having a hole diameter larger than the shaft regulating shaft insertion hole 23 (not shown in this drawing) directly above the shaft regulating shaft insertion hole 23 from above the shaft regulating shaft 14. The press-fit head 34 having the shaft through-hole 33 is brought into contact with the rotating yoke 32. At this time, at the same time, by attaching the backup head 35 to the lower end of the shaft regulating shaft 14 and moving the shaft regulating shaft 14 against the urging direction of the urging member 17, the shaft 31 is attached to the rotating yoke 32. As shown in FIG. 5, the press-fit head 34 and the backup head 35 are returned to their original ones.
[0023]
Next, as shown in FIG. 6, from the upper side of the shaft regulating shaft 14, the hole diameter is such that the shaft regulating shaft insertion hole (not shown in FIG. 6) is sandwiched immediately above the shaft regulating shaft insertion hole 23. The positioning head 38 having the positioning head regulating shaft insertion hole 36 and the shake head 37 for measuring shake is lowered, and the positioning head regulating shaft insertion hole 36 is inserted into the shaft 31 and held. At this time, the tip of the deflection head 37 of the positioning head 38 is in contact with the rotating yoke 32. Thereafter, the backup cylinder 39 is brought into contact with the lower end of the shaft regulating shaft 14 to move the shaft regulating shaft 14 against the urging direction of the urging member 17. In this state, the drive ring 40 of the drive pulley 41 is brought into contact with the outer surface of the rotary yoke 32, and the rotary yoke 32 is rotated by the rotation of the drive pulley 41, and the deflection of the rotary yoke 32 assembled to the shaft 31 is defined. Is measured by the shake head 37 as to whether the value is within the range of the above.
[0024]
Next, after the positioning head 38, the backup cylinder 39, and the drive pulley 41 are returned to their original positions, the rotary yoke 32 is turned over for a post-process operation. At this time, the original upper end side of the shaft 31 is inserted through the shaft regulating shaft insertion hole 23 of the shaft regulating bush 22.
[0025]
Next, as shown in FIG. 7, the rotor positioning head 43 having the rotor positioning head insertion hole 42 into which the shaft 31 is inserted is lowered from above the rotating yoke 32, and the rotor positioning head insertion hole 42 is inserted into the shaft 31. At the same time, the tip of the rotor positioning head 43 comes into contact with the inner surface of the rotary yoke 32 and is sandwiched between the upper surface of the rotor holding base 11. Subsequently, the height measuring head 44 is lowered from above the shaft 31 in the rotor positioning head insertion hole 42 and is brought into contact with the shaft 31 to determine whether the height of the shaft 31 is within a desired specified value. After measurement, the rotor positioning head 43 is returned to the original position.
[0026]
Next, as shown in FIG. 8, the shaft regulating pin 45 is lowered from above the shaft 31 , and abuts on the upper end of the shaft 31 to hold the shaft 31 . Subsequently, the adhesive application nozzle 46 is lowered so as to contact the inner surface of the rotating yoke 32, and the driving pulley 41 is moved so that the outer surface of the rotating yoke 32 and the driving ring 40 are in contact with each other. After the rotation, the adhesive 47 is applied to the inner surface of the rotating yoke 32. Thereafter, the shaft regulating pin 45 and the adhesive application nozzle 46 are returned to their original positions.
[0027]
Finally, as shown in FIG. 9, the magnet 48 is mounted on the inner surface of the rotating yoke 32, and the adhesive 47 is cured by irradiating or heating with ultraviolet rays to complete the assembly of the rotor.
[0028]
【The invention's effect】
As described above, the present invention can provide a rotor assembling apparatus with improved assemblability by easily and accurately regulating the rotating yoke and the shaft.
[0029]
In addition, the provision of the insertion hole on the side surface of the rotor holder allows the hollow hole of the rotor holder to be visually observed, thereby providing an effect of providing a rotor assembling apparatus capable of confirming a failure.
[0030]
Further, by providing the switching member detachably on the outer peripheral surface of the rotor holding base, there is an effect that it is possible to provide a rotor assembling apparatus that can be used regardless of the type of the rotor.
