[0066] Working principle:

[0067] Open the box door, manually pull up the pull block 333, the pull rod 335 and the plug block 336 to compress the spring 334 to pull the plug block 336 out of the limiting base 34, release the limit on the push-pull plate 32, then put the stator on the top of the unloading table 37, and then push the push-pull plate 32 back into the box so that the workpiece 38 is located between the two heating parts 47. When pushing it back, the plug block 336 contacts the arc surface and the compression spring 334 moves to the top of the limiting base 34 and is inserted into the jack to limit the push-pull plate 32.

[0068] Then start the cylinder 5 81 to move the connecting frame 84 and the air outlet nozzle 82 upward, so that the air outlet nozzle 82 is connected with the air inlet end of the air pipe of the air nozzle 83;

[0069] Close the box door, start the program through the data display 13, and then start the program again through the PLC controller 14. The PLC controller 14 controls the cylinder 42 to operate and push the piston rod out, so that the clamping part 48 is close to the unloading table 37, and the heating part 47 is close to the workpiece 38. Then the PLC starts the heating part 47 to heat the workpiece 38. The temperature sensor 39 obtains the temperature at the middle position of the stator. When the temperature reaches the specified temperature, it means that the stator shell has also reached a certain temperature. The expansion coefficients of the stator shell and the stator core are different. When the stator shell is heated, the temperature of the stator core is lower and the expansion speed is slow. Therefore, after the stator shell expands, a slight gap will appear at the contact position with the stator core, thereby reducing The friction force is then generated, and the hydraulic cylinder 71 is started to push the mounting plate 72 and the structure installed at the bottom of the mounting plate 72 downward, so that the multiple contact members 75 pass through the extraction port 1 59 and the extraction port 2 510 and are inserted into the middle of the stator core. Then the cylinder 4 77 is started to extend the piston rod to move the moving ring 78 and the mounting ring 79 fixed at the bottom of the moving ring 78 downward to the middle mounting ring 79, thereby reducing the distance between the two. Then, the mounting ring 79 moves downward, and the connecting rod 2 710 connected thereto pushes the contact member 75 toward the inner wall of the stator core and squeezes the inner wall of the stator core. At the same time, the cylinder 2 53 is started to extend the piston rod to move the connecting rod 1 54 and the moving frame 55 downward. The moving frame 55 moves downward, driving the structure installed above to move downward, so that the shell limit The positioning piece 56 presses the top of the stator shell. When processing different shells, it is necessary to replace the shell limiting piece 56 that matches the stator. Then the hydraulic cylinder 71 retracts the piston rod and pulls the mounting plate 72 and the structure at the bottom of the mounting plate 72 upward. When the contact piece 75 moves upward, the stator core is pulled upward and separated from the stator shell. The stator core passes through the extraction port 1 59 and the extraction port 2 510 to the top. Then the control cylinder 3 61 extends the piston rod to push the slide 62 and the hollow placement rack 63 to move, so that the two hollow placement racks 63 block the extraction port 1 59 below. Then the cylinder 4 77 is started to retract the piston rod, and the uppermost mounting ring 79 pulls the connecting rod 2 710 connected to it upward, so that the contact piece 7 5 is away from the inner wall of the stator core, so that the pulled out electronic core falls on the hollow placement rack 63, and then the cooling device is started to supply cold air to the air outlet nozzle 82. The cold air passes through the air pipe and is ejected from the air nozzle 83 to the surface of the stator shell, and then the stator shell is cooled. At the same time, the exhaust fan 22 is started to extract the internal hot air, so that the stator shell is quickly cooled. Then the cylinder 2 53 is started to retract the piston rod to move the movable rack 55 upward to contact the stator shell, and then the box door is manually opened. The pull block 333, the pull rod 335 and the plug block 336 are manually pulled up to compress the spring 1 334 to pull the plug block 336 out of the limit base 34, release the limit on the push-pull plate 32, and then the stator is taken down from the discharge table 37, and then the stator core is taken out to complete the processing.
