The press-fitting upper plate 532 is a hollow plate and is disposed on the outer periphery of the press-fitting driving member 52, so that the press-fitting driving member 52 does not interfere with the press-fitting driving member while the height of the press-fitting device 5 can be controlled. The press-fitting lower plate 533 is connected to the telescopic end of the press-fitting driving member 52, and the press-fitting frame 53 is lifted up and down by the press-fitting driving member 52.

In order to improve the quality of press-fitting, the press-fitting device 5 of the present embodiment implements the separate press-fitting of the rotor 13 and the end cover 14 by using one press-fitting driving member 52, and press-fitting of the rotor 13 and the barrel 12, the fan blade 11 is performed first, and then press-fitting of the end cover 14 and the rotor 13, the barrel 12 is performed.

The end cap press-fitting mechanism 55 is provided on the press-fitting frame 53 and is located at the outer periphery of the rotor press-fitting mechanism 54.

Specifically, the end cap press-fitting mechanism 55 includes an end cap press-fitting plate 551, a plurality of columns 552, and an end cap press core 553.

In addition, the end cover pressing core 553 and the end cover pressing plate 55 can be integrally arranged or separately arranged, preferably separately arranged, so that when the end cover pressing core 553 is worn, the end cover pressing core 553 can be conveniently and quickly replaced, and meanwhile, the cost is reduced.

As shown in fig. 12, a rotor press-fitting mechanism 54 is provided in the middle of a press-fitting lower plate 533 of the press-fitting frame 53, which includes a rotor press-fitting sleeve 541 for rotor guiding, a rotor press-core 542 for rotor press-fitting, and a press-fitting switching unit.

A rotor press-fitting sleeve 541 having an inlet 5414 is fixed to a lower end surface of a press-fitting lower plate 533 of the press-fitting frame 53; the rotor core 542 is movably disposed inside the rotor casing 541 by a press-fit spring 543, and a press-fit switching unit is used to lock/unlock the positional relationship between the rotor core 542 and the rotor casing 541.

Specifically, the press-fit switching unit includes a switching driver 544 and a stopper 545. The switching drive 544 is fixed to the press-fitting frame 53, preferably as a cylinder. The blocking member 545 is rectangular and is connected to the switching driving member 544 to realize horizontal movement. A blocking hole 5413 into which the blocking member 545 is inserted is formed in the middle of the rotor press-fitting sleeve 541.

When the blocking member 545 is inserted into the blocking hole 5413 and the press-fitting driving member 52 drives the press-fitting frame 53 to press down, the upper end of the rotor 13 first extends into the inlet 5414 and abuts against the rotor pressing core 542, the rotor pressing core 542 is blocked by the blocking member 545, that is, the rotor pressing core 542 is locked inside the rotor press-fitting sleeve 541, and press-fitting of the rotor 13, the machine barrel 12 and the fan blade 11 can be achieved at this time. At this time, the end cap press-fitting mechanism 55 has not yet acted on the end cap 14. Then, after the blocking member 545 leaves the blocking hole 5413, when the press-fit driving member 52 drives the press-fit frame 53 to press down continuously, the rotor press core 542 can move in the rotor press-fit sleeve 541, so that no pressing force is generated on the rotor 13, and at this time, the end cover press-fit mechanism 55 presses down the end cover 14 to press-fit the rotor 13 and the barrel 12.

Specifically, the rotor press-fitting sleeve 541 includes an upper press-fitting sleeve 5411 provided with the blocking hole 5413 and a lower press-fitting sleeve 5412 provided with the introduction port 5414, which are fixedly connected by screws.

The diameter of the upper through-hole 5415 is smaller than the diameter of the lower through-hole 5416. The press-fitting spring 543 is sleeved on the pressing rod portion 5421 and abuts between the press-fitting portion 5422 and the upper press-fitting sleeve 5411. In a normal state, the press-fit spring 543 applies a force to the rotor core 542 near the introduction port 5414.

In addition, the upper end of the rotor core 542 is generally not separated from the upper through hole 5415, that is, when the rotor core 542 and the rotor press-fitting sleeve 541 are in a locked state, a portion of the upper end of the rotor core 542 is in the upper through hole 5415 and abuts against the blocking member 545, so that the rotor core 542 is conveniently moved in the upper through hole 5415 of the upper press-fitting sleeve 5411 after the locking is subsequently released, and the locking is not occurred. At this time, the lower end of the rotor core 542 is just abutted against the inlet 5414 of the lower press-fitting sheath 5412, so that the length of the rotor press-fitting sheath 541 can be effectively controlled.

Since the blocking member 545 needs to transmit a downward pressure when the rotor 13 is press-fitted. To increase stability, the blocking holes 5413 extend radially through the upper press-fit sleeve 5411 and the upper through holes 5415. When the rotor pressing core 542 needs to be fixed, the blocking piece 545 is transversely inserted between the whole upper pressing sleeves 5411, both ends of the blocking piece 545 are blocked by the upper pressing sleeves 5411, and when the rotor 13 is pressed, the blocking piece 545 is not easy to deform or shift, so that stable operation of the rotor pressing core 542 is effectively ensured.

Preferably, the press-mounting frame 53 is provided with a core avoiding hole 531 for the rotor core 542, so that the rotor core 542 can be moved conveniently, and the length of the rotor press-mounting sleeve 541 can be reduced, so that the structure is compact.

The contact surface of the pushing member 563 is a slope and contacts the lower end of the support core 562. The ejector driver 564 is preferably a cylinder for providing motive force for movement of the ejector 563.

When the press-fitting device 5 needs to be press-fitted, the pushing driving piece 564 pushes the pushing piece 563 to translate, and under the action of the inclined plane, the supporting core 562 moves upwards, so that the supporting core abuts against the tool bottom plate 91, the stability of the workpiece positioning device 9 is ensured, the inclination of the turntable is prevented, and the press-fitting effect of the motor is ensured. When the press-fitting is completed, the pushing driving member 564 drives the pushing member 563 to reset, and the supporting core 562 falls down under gravity and leaves the tooling bottom plate 91, so as to ensure that the workpiece positioning device 9 can smoothly move to the next station.

Preferably, the supporting core 562 is movably disposed in the supporting seat 561 by a supporting spring 565, so as to prevent gravity failure, and the supporting core 562 does not automatically drop.
