A stator thermal disassembly machine

Abstract

The present invention discloses a stator thermal disassembly machine, which relates to the technical field of stator disassembly. It includes an installation control mechanism, and further includes: an air extraction mechanism installed on one side of the installation control mechanism for extracting the gas in the installation control mechanism after the processing; a loading and unloading mechanism connected to the installation control mechanism for loading and unloading the stator; a heating mechanism connected to the installation control mechanism for heating the outer shell of the stator; a housing limiting mechanism connected to the installation control mechanism for limiting the stator housing during thermal disassembly. By heating the outer shell of the stator, the outer shell of the stator expands thermally, so that a gap appears at the contact position between the outer shell of the stator and the stator core. At the same time, heating reduces the adhesive strength of the adhesive and the strength of the welding points, so that the stator core can be separated from the outer shell of the stator more quickly, reducing the damage caused by the separation of the outer shell of the stator and the stator core, ensuring the integrity of the structure, and improving the recycling rate.

A workpiece 38 is installed on the blanking table 37. The temperature sensor 39 is electrically connected to the PLC controller 14 and the data display 13;

[0054] It also includes a spring limiting member 33. The spring limiting member 33 includes a bolt 331 threadedly sleeved inside the push-pull plate 32. A spring hole 332 is formed in the center of the bolt 331. A pull rod 335 is sleeved inside the spring hole 332. An insertion block 336 is fixed to the bottom end of the pull rod 335. The insertion block 336 is sleeved inside the spring hole 332. A first spring 334 is fixed to the top of the insertion block 336.

A limiting base 34 is fixed to the inner bottom wall of the box body 12. An arc surface is formed on one side of the limiting base 34. The insertion block 336 is sleeved inside the top jack of the limiting base 34.

[0055] The heating mechanism 4 includes two support frames 41 symmetrically fixed to the inner bottom wall of the box body 12. A first cylinder 42 is fixed inside the support frame 41. The two first cylinders 42 are symmetrical. The output end of the first cylinder 42 is fixed with a first connecting plate 43.

A heating part 47 is fixed to the heating part mounting frame 46. The heating part 47 includes, for example, Figure 10 the arc-shaped heater 471 as shown in

The distance sensor obtains the contraction movement distance of the active rod 4724. If the contraction distance is long, it means that the heating block 4725 contacts the position of the stator protrusion. Since one piece of the stator protrusion is thicker than the non-protruding position, it is necessary to increase the power of this heating block 4725 and multiple heating blocks 4725 around this heating block 4725 to make its heating temperature higher than that of the non-protruding heating block 4725, so as to make the temperature rising speed of the stator housing consistent, avoid inconsistent expansion caused by inconsistent temperature, thereby avoiding poor expansion effect, large friction force and large pulling force at some places, which may cause greater damage to the stator core and the stator housing.

The fifth cylinder 81 and the cooling device are both electrically connected to the PLC controller 14 and the data display 13.

[0066] Working principle:

[0067] Open the box door, manually lift the pulling block 333, the pull rod 335 and the inserting block 336 to compress the first spring 334 and pull out the inserting block 336 from the limit base 34 to release the limit on the push-pull plate 32. Then place the stator on the top of the blanking 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, after the inserting block 336 contacts the arc surface, it compresses the first spring 334 and moves to the top of the limit base 34 and inserts into the jack to limit the push-pull plate 32;

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

[0069] Close the box door. After starting the program through the data display 13, start the program again through the PLC controller 14. The PLC controller 14 controls the operation of the first cylinder 42 to push out the piston rod, making the clamping member 48 approach the feeding table 37 and the heating part 47 approach 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 housing has also reached a certain temperature. The expansion coefficients of the stator housing and the stator core are different, and when the stator housing is heated, the heat of the stator core is lower and the expansion speed is slow. Therefore, after the stator housing expands, there will be a slight gap at the contact position between the stator housing and the stator core, thereby reducing the friction force. Then start the hydraulic cylinder 71 to push the mounting plate 72 and the structure mounted at the bottom of the mounting plate 72 downward, so that multiple contact members 75 pass through the first blanking port 59 and the second blanking port 510 and are inserted into the middle of the stator core. Then start the fourth cylinder 77 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 close to the middle mounting ring 79, reducing the distance between the two. Then when the mounting ring 79 moves downward, it will push the contact member 75 toward the inner wall of the stator core through the connecting rod two 710 connected to it and squeeze the inner wall of the stator core. At the same time, start the second cylinder 53 to extend the piston rod to move the connecting rod one 54 and the moving bracket 55 downward. The downward movement of the moving bracket 55 drives the structure mounted above to move downward, so that the housing limiting member 56 presses the top of the stator housing. When processing different housings, it is necessary to replace the housing limiting member 56 matching the stator. Then the hydraulic cylinder 71 contracts the piston rod and pulls the mounting plate 72 and the structure at the bottom of the mounting plate 72 upward. When the contact member 75 moves upward, it pulls the stator core upward to separate it from the stator housing. The stator core passes through the first blanking port 59 and the second blanking port 510 to the upper part. Then control the third cylinder 61 to extend the piston rod to push the slide table 62 and the hollow placing rack 63 to move, so that the two hollow placing racks 63 block the first blanking port 59 below. Then start the fourth cylinder 77 to retract the piston rod, pulling the uppermost mounting ring 79 and the connecting rod two 710 connected to it upward, so that the contact member 75 is away from the inner wall of the stator core, and the removed electronic core falls on the hollow placing rack 63. Then start the cooling device to supply cold air to the air outlet nozzle 82. The cold air passes through the air pipe and is sprayed out from the jet nozzle 83 to the surface of the stator housing, and then cools the stator housing. At the same time, start the exhaust fan 22 to extract the internal hot air, so that the stator housing cools down quickly. Then start the second cylinder 53 to retract the piston rod to move the moving bracket 55 upward to release the pressing on the stator housing. Then manually open the box door, manually pull up the pull block 333, the pull rod 335 and the insert block 336 to compress the first spring 334 and pull out the insert block 336 from the limit base 34, releasing the limit on the push-pull plate 32. Then take the stator off the feeding table 37, and then take out the stator core to complete the processing.

[0070] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto.
