[0022] In this embodiment, the electromagnetic induction heater 17 is a prior art and will not be described in detail. When the servo motor housing is heat treated, the servo motor housing is heat treated through the circuit flow between the two groups of contact blocks 16 and the yoke iron heating plate 14.

[0024] In this embodiment, the moving block 50 can be restricted by the arc-shaped guide cavity 25 to prevent the moving block 50 from detaching from the arc-shaped guide plate 20. At the same time, when the moving block 50 is displaced to the lowest point of the arc-shaped guide cavity 25, the servo motor housing is subjected to loading processing. When the moving block 50 is displaced to the highest point of the arc-shaped guide cavity 25, the servo motor housing is subjected to heat treatment.

The driving chain 41 is displaced on the driven gears 42 , so that the moving block 50 is displaced in the arc-shaped guide cavity 25 .
[0026] In this embodiment, when the moving block 50 needs to be displaced in the arc-shaped guide cavity 25, the drive chain 41 is displaced between the two sets of driven gears 42, thereby driving the moving block 50 on the drive chain 41 to be displaced in the arc-shaped guide cavity 25, completing the position adjustment of the yoke iron heating plate 14.
[0027] Specifically, the arc-shaped guide plate 20 is provided with two groups of driven rotating cavities 24, and the driven rotating cavities 24 are connected to the arc-shaped guide cavity 25. The two groups of driven gears 42 are respectively arranged in the two groups of driven rotating cavities 24, and the driven gears 42 are rotatably set on the arc-shaped guide plate 20, so that the driving chain 41 is displaced in the arc-shaped guide cavity 25.

[0030] In this embodiment, when the driving moving block 50 is displaced in the arc-shaped guide cavity 25, the driving servo motor 43 is turned on to rotate the driving gear 44, thereby causing the driving chain 41 on the driving gear 44 to be displaced, thereby causing the moving block 50 on the driving chain 41 to be displaced in the arc-shaped guide cavity 25, thereby adjusting the position of the yoke iron heating plate 14.
[0031] Specifically, a positioning hole 15 is provided on the yoke iron heating plate 14; The moving block 50 is provided with a threaded hole 51 therethrough. A positioning screw 60 is disposed in the threaded hole 51 . The positioning screw 60 is threadedly connected in the threaded hole 51 .
[0032] Specifically, the diameter of the positioning hole 15 is larger than the diameter of the positioning screw 60; A positioning plate 61 is disposed on the positioning screw 60 , and the positioning plate 61 contacts the surface of the moving block 50 , so that the positioning screw 60 extends into the inner cavity of the positioning hole 15 .

When the moving block 50 is displaced and lifted, the yoke iron heating plate 14 is driven to be displaced and lifted onto the two groups of contact blocks 16; Of course, since the diameter of the positioning hole 15 is larger than the diameter of the positioning screw 60, the inner wall of the positioning hole 15 and the positioning screw 60 are in an active state, so that the bottom of the servo motor housing is parallel to the ground during the lifting process of the servo motor housing, so that the servo motor housing remains stable, and the yoke iron heating plate 14 remains stable, so that the bottom end surface of the yoke iron heating plate 14 is in contact with the contact block 16; Of course, since the diameter of the positioning hole 15 is larger than the diameter of the positioning screw 60, the inner wall of the positioning hole 15 and the positioning screw 60 are in an active state. When the yoke heating plate 14 is placed on the two groups of contact blocks 16, the moving block 50 can be moved back and forth to make the positioning screw 60 move back and forth in the positioning hole 15, driving the yoke heating plate 14 to displace and adjust its position, so that the yoke heating plate 14 can fully contact the contact block 16.

If it is unstable, the moving block 50 is driven to move to the position before lifting, the servo motor housing is put down, and S30 is repeated until the yoke iron heating plate 14 is stably connected with the two groups of moving blocks 50; S50, secondary drive: After S40 is completed, the driving assembly 40 continues to drive the moving block 50 to move and lift in the arc-shaped guide cavity 25, so that the yoke iron heating plate 14 is lifted and drives the servo motor housing to lift out of the placement area, and the servo click housing is moved to the highest point of the arc-shaped guide cavity 25; S60, Correction: After S50 is completed, the driving assembly 40 drives the moving block 50 to move back and forth at the highest point of the arc-shaped guide cavity 25, so that the positioning screw 60 moves back and forth in the positioning hole 15, and adjusts the position of the yoke heating plate 14 until the yoke heating plate 14 is in stable contact with the two groups of contact blocks 16, and then the servo motor housing is heat treated by the electromagnetic induction heater 17.
