Preferably, the base 110 is rotatable with respect to the radial press-fitting mechanism 200 and the axial press-fitting mechanism 300, so that the assembly of all the copper blocks 101 is sequentially completed by the rotation angle in the multiple press-fitting process. For example, sixty mounting grooves 102 are formed in one end of the rotor, the radial press-fitting mechanism 200 comprises ten sets of material placing cavities 211 and radial push rods 220 which are uniformly distributed in the circumferential direction, the ten copper blocks 101 can be assembled simultaneously in each radial press-fitting action, and the next set of ten copper blocks 101 is continuously pressed and fitted by rotating the rotor or the base 110 by 6 degrees after each radial press-fitting action is completed until the sixty mounting grooves 102 are assembled.

With the axial press-fitting mechanism 300 pressed against the top end of the rotor, the positioning end 321 of the column 320 contacts the top end of the rotor, so that the ground of the positioning end 321 presses against the rotor. Meanwhile, the diameter of the cylinder 320 is preferably smaller than or equal to the diameter of the inner circumferential space formed by the copper bars on the rotor, so that when the positioning end 321 contacts with the top end of the rotor, the outer circumferential surface of the positioning end 321 forms a stop at the inner side of the mounting groove 102, and the radial assembling depth of the copper block 101 can be accurately controlled.

When the axial press-fitting mechanism 300 is press-fitted to one end of the rotor, the stop grooves 322 correspond to the mounting grooves 102 of the rotor one to one, so that the pressed copper blocks 101 are limited and stopped by the stop grooves 322 after entering the mounting grooves 102.
Preferably, the axial press-fitting mechanism 300 further includes a flattening unit 330 for flattening the copper block 101 in the axial direction of the rotor, and after the copper block 101 is press-fitted in place in the radial direction, the flattening unit 330 presses the copper block 101 in the axial direction to flatten the copper block, thereby further improving the assembly accuracy.

The substrate 310 may be a part of the secondary stage 130 or a mounting plate detachably mounted on the secondary stage 130. When the radial press-fitting mechanism 200 works, the first axial driver 331 drives the flattening piece 332 to be away from the rotor, and after the copper block 101 is pressed in place in the radial direction, the first axial driver 331 drives the flattening piece 332 to press down until the copper block 101 is flattened to the same height.

After the assembly operation is completed, the second axial driver 341 of the detaching unit 340 drives the pushing block 342 to move towards the rotor, so as to assist the rotor to detach from the axial press-fitting mechanism 300 and prevent the rotor from being taken away from the base 110 during the upward movement of the axial press-fitting mechanism 300.
To monitor the press-fitting operation in real time during the operation of the assembling apparatus, the radial press-fitting mechanism 200 preferably includes a pressure sensor 231 for measuring a driving resistance during the driving of the radial driver 230. The pressure sensor 231 may be disposed on the driving rod of the radial actuator 230, or disposed on the radial push rod 220, or connected between the radial actuator 230 and the radial push rod 220 as shown in fig. 7, so as to monitor whether the press-fitting process of the copper block 101 is successful during the process of radially pushing the copper block 101. For example, when the copper block 101 cannot be pushed smoothly due to the foreign matter stuck in the material placing cavity 211, the driving resistance of the radial driver 230 measured by the pressure sensor 231 is large, so that the worker can find the abnormality in real time to process the abnormality.
In order to improve the assembling efficiency, besides real-time monitoring of the assembling device during operation, the copper block 101 should maintain a moving posture during being pushed radially so as to smoothly enter the installation groove 102. In order to restrict the moving direction of the copper block 101 in the material placing cavity 211, a guiding structure is preferably arranged in the material placing cavity. As shown in fig. 7 and 8, the bottom of the material placing cavity 211 is formed with a guide groove 213 with a width greater than or equal to the thickness of the copper block 101, and when the copper block 101 is in the material placing cavity 211, the guide groove 213 is in sliding fit with the bottom end of the copper block 101 to provide a guiding function.

The top of the loading cavity 211 is preferably open so that the copper block 101 can be loaded from above the press-fitting seat 210. The feeding operation may be performed manually by a worker or, preferably, automatically by a feeding unit. As shown in fig. 9, the asynchronous motor rotor copper block assembling device preferably comprises a feeding unit, wherein the feeding unit comprises a moving mechanism and a grabbing mechanism, the grabbing mechanism is used for grabbing the copper block 101, moving the copper block to the position above the press-fitting seat 210 by using the moving mechanism, and putting the copper block 101 into an opening above the material placing cavity 211 so as to complete feeding.

The moving mechanism may be a mechanical arm or a three-axis moving platform, and the distribution positions of the plurality of clamping jaws 402 preferably correspond to the distribution positions of the material placing cavities 211 of the press-fitting seat 210, so as to release the plurality of copper blocks 101 in the material placing cavities 211 simultaneously.
According to the asynchronous motor rotor copper block assembling device in the preferred embodiment of the present application, during the assembling operation, a worker first positions the pre-assembled rotor on the base 110, and then controls the primary workbench 120 to descend, so that the central hole 212 of the press-fitting seat 210 is sleeved on the rotor and the inner outlet of the material placing cavity 211 is aligned with the mounting groove 102 of the rotor. The feeding unit simultaneously grabs a plurality of copper blocks to the upper side of a plurality of material placing cavities 211 of the press-fitting seat 210, and releases the copper blocks 101 to enter the material placing cavities 211, so that the feeding is completed. The copper block 101 is in sliding fit with the guide groove 213 at the bottom in the material placing cavity 211, and the two sides are laterally restrained by the plurality of arc-shaped protrusions 214 for carrying out point contact on the copper block 101. After the preparation, the secondary stage 130 is lowered to press the positioning end 321 of the column 320 against the top of the rotor and form a stop inside the mounting groove 102. Then, the plurality of radial drivers 230 simultaneously drive the plurality of radial push rods 220 to push the copper blocks 101 into the mounting grooves 102, and the first axial driver 331 of the flattening unit 330 drives the flattening piece 332 to flatten the plurality of copper blocks 101, thereby completing one round of assembly process.
