In addition, teeth (not shown) meshing with teeth 671 of the belt 67 are formed on the outer peripheral surfaces of the pulleys 63 to 66. A belt 67 between the drive pulley 64 and the auxiliary pulley 65 is wound around the pulleys 63 provided at the bottom of each of the four continuous work placing tables 61 located at the heating station B. ..

As shown in FIG. 4, a slide base 662, which is slidably inserted into a rod 663 bridged between a pair of pedestals 665, 665, is attached to the lower portion of the shaft 661 of the tension pulley 66. Has been. A rod 663 is inserted into a spring 664 provided between the slide base 662 and one pedestal 665. Therefore, the tension pulley 66 is always urged in the direction of arrow S. The pedestals 665 and 665 are mounted on the turntable mounting plate 53 of the high frequency heating device H 1.

As shown in FIG. 2, the front stage of the heating station B is a carry-in station A in which four ball studs are placed on the work placing table 61, and the rear stage of the heating station B is a ball stud burner. It becomes a cooling station C for entry. The cooling station C is provided with a work rotating device (not shown) similar to the work rotating device 60 provided near the heating station B. Following the cooling station C is a carry-out station D for removing the four ball studs from the work mounting table 61.

Next, the operation of this embodiment will be described. First, the case of heating the first ball stud 70 will be described. Although not shown in FIG. 2, the heating coil 90 described in FIG. 9 is attached to the heating station B shown in FIG. The electromagnetic coil 35 of the first clutch 30 is not excited, but the electromagnetic coil 45 of the second clutch 40 is excited. Then, since the shoe 31 of the first clutch 30 is pressed against the flange member 111 by the resilience of the disc spring 33, the Geneva gear 11 has the flange member 111, the shoe 31, the movable piece 32, the spline 35, and the sleeve. 38, and a key 381, and is connected to the rotating shaft 50.

Therefore, when the motor 18 is intermittently operated so that the output shaft 14 of the speed reducer 15 rotates in the direction of arrow A in this state, the kick plate 13 attached to the output shaft 16 of the speed reducer 15 is intermittently operated. When the Geneva large gear 11 that is integrated with the Geneva small gear 12 rotates intermittently, the rotation shaft 50 moves in the direction of arrow C (clockwise), that is, the turn table T moves in the direction of arrow C. It intermittently rotates. At this time, the motor 18 is intermittently operated so that the turntable T is rotated by 90 degrees by one-step continuous rotation of the motor 18.

When the motor 68 is started and the motor 68 that rotates the drive pulley 64 is started to rotate the belt 67 in the direction of the arrow D (counterclockwise), the distance between the drive pulley 64 and the pulley 65 is increased. The four work rests 61 equipped with pulleys 63 driven by belts 67 rotate in the direction of arrow R (clockwise).

However, since the electromagnetic coil 45 of the second clutch 40 is excited, the movable piece 42 overcomes the elastic force of the disc spring 43 and is attracted to the yoke 452 of the electromagnetic coil 45. Since there is a gap g between 521 and 521, the edge between the gear 52 and the output shaft 21 is cut. Further, since the motor 25 is not in operation, the output shaft of the motor 25 is fixed by the brake, so the output shaft 21 of the speed reducer 22 is also fixed. Therefore, even if the gear 52 is intermittently rotatably driven by the gear 51 that is rotated by intermittent rotation of the rotating shaft 50, the output shaft 21 of the reduction gear 22 does not rotate.

After placing the first ball studs 70 on the four work rests 61 of the carry-in station A, the turntable T is rotated in the direction of the arrow C in a step of one step to move the four first ball studs 70. Reaches heating station B. Then, since the work rest 61 is rotated in the direction of arrow R by the belt 67, the four first ball studs 70 are also rotated in the direction of arrow R. Then, the four first ball studs 70 are heated by the heating coil 90 shown in FIG. 9 as described in the conventional technique.

When this heating is completed, the turntable T is rotated in a stepwise direction in the direction of the arrow C, and the four first ball studs 70 reach the cooling station C, and the workpieces provided in the cooling station C are cooled. While being rotated by the mounting table rotating device, it is cooled by the cooling liquid injected from the cooling jacket (not shown). After the cooling is completed, the turntable T is rotated in the direction of arrow C in a one-step step to reach the carry-out station D, and the four first ball studs 70 are removed from the work mounting table 61. ..

Next, heating of the second ball stud 80 will be described. Although not shown in FIG. 2, the heating coil 99 described in FIG. 10 is attached to the heating station B shown in FIG. The electromagnetic coil 35 of the first clutch 30 is excited and the electromagnetic coil 45 of the second clutch 40 is not excited. Then, since the movable piece 32 of the first clutch 30 is attracted to the movable piece receiving member 34, there is a gap G between the shoe 31 and the flange member 111, so that the Geneva gear 11 and the rotary shaft are rotated. The edge with 50 is cut off.

On the other hand, since the electromagnetic coil 45 of the second clutch 40 is not excited, the shoe 32 is pressed against the flange member 521 by the resilience of the disc spring 43. Therefore, the gear 52 is the flange member 521, the shoe 41, It is coupled to the output shaft 21 of the speed reducer 22 via the movable piece 42, the spline 45, the sleeve 48, and the key 481. Therefore, when the motor 25 is started in this state and continuously operated, the output shaft 21 of the speed reducer 22 rotates in the direction of the arrow B, and the rotary shaft 50 of the turntable T is rotated via the gears 52 and 51. Rotate continuously in the direction. Along with the activation of the motor 25, the drive motor 68 of the drive pulley 64 is activated to rotate the belt 67 in the direction of arrow D.

When four continuous work mounting bases 61 of the rotating turntable T come to the loading station A, after mounting the four second ball studs 80 on these work mounting bases 61, turn By the rotation of the table T, the four second ball studs 80 reach the heating station B one after another. Then, the work mounting table 61 is heated while passing through the heating coil 99 while being rotated by the belt 67 in the direction of the arrow R 1. The heated second ball stud 80 successively reaches the cooling station C, and is cooled by the cooling liquid jetted from a cooling jacket (not shown) while being rotated by the work table rotating device provided in the cooling station C. After that, it further reaches the carry-out station D, is removed from the work mounting table 61, and is carried out.
