Description

Technical Field

The motor rotor docking assembly device also includes a lifting device, the upper surface of the lifting device is detachably connected to the integrated shell. When the motor rotor is docked with the integrated shell, the motor rotor and the integrated shell are respectively installed at corresponding positions of the rotor positioning device and the lifting device. The lifting device moves toward the rotor positioning device, thereby pushing the integrated shell toward the motor rotor until the integrated shell and the motor rotor are docked and assembled.

However, the above scheme still has the following shortcomings: there will be a certain deviation when fixing the position of the integrated shell, which may cause the integrated shell to be unable to be accurately docked with the rotor, resulting in the need for multiple positioning between the integrated shell and the rotor to complete the docking.

[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] like Figure 1-Figure 5 As shown, a docking mechanism for assembling a motor rotor includes an adjustment platform 1, a loading platform 2 is arranged inside the adjustment platform 1, a rotor fixing cover 3 is arranged above the adjustment platform 1, a laser signal transmitter 14 is fixed to the top surface of the loading platform 2, a laser signal receiver 15 is fixed to the bottom surface of the rotor fixing cover 3, an integrated shell fixing device 16 is fixed to the middle position of the top surface of the laser signal transmitter 14, and a rotor positioning device 17 is fixed to the center of the bottom surface of the laser signal receiver 15. The rotor positioning device 17 is an existing structure, and reference can be made to the Chinese public patent with the publication (announcement) number: CN218888353U. The rotor positioning device 17 in the present application document is the rotor positioning device in the cited document. Two first transmission holes 18 are respectively provided on the lower halves of the front and rear sides of the adjusting platform 1, wherein every two corresponding first transmission holes 18 form a group, and a first rotating shaft 5 is rotatably arranged between each group of first transmission holes 18, and a synchronous gear 6 is fixed to the peripheral wall of the first rotating shaft 5. A first driving motor 4 is fixed to the front side of the adjusting platform 1, and the output end of the first driving motor 4 extends to the inside of the first transmission hole 18 and is fixed to one end of the first rotating shaft 5. Two first gear grooves 7 are provided on the bottom surface of the loading platform 2, and the first gear grooves 7 are distributed along the axial direction of the synchronous gear 6, and the first gear grooves 7 are meshed with the synchronous gear 6. A second transmission hole 19 is respectively provided on the upper halves of the left and right sides of the adjusting platform 1, and a second rotating shaft 9 is rotatably arranged between the two second transmission holes 19, and second gear bodies 10 are respectively fixed to the peripheral walls at both ends of the second rotating shaft 9, and a second driving motor 8 is fixed to the left side of the adjusting platform 1, and the output end of the second driving motor 8 extends to the inside of the second transmission hole 19 and is fixed to one end of the second rotating shaft 9. Two second gear grooves 11 are provided on the top surface of the loading platform 2, and the second gear grooves 11 are meshed with the second gear body 10.

[0025] During use, the staff starts the laser signal transmitter 14, and the laser signal transmitter 14 will emit a laser. If the laser signal receiver 15 cannot receive the laser signal, it means that the integrated shell fixing device 16 and the rotor positioning device 17 are not aligned. At this time, the PLC controller 23 will control and start the first drive motor 4 and the second drive motor 8. The first drive motor 4 will drive the first rotating shaft 5 to start rotating, and the first rotating shaft 5 will drive the synchronous gear 6 to rotate. The synchronous gear 6 and the first gear groove 7 are meshed, and the synchronous gear 6 drives the loading platform 2 to translate forward and backward. The second drive motor 8 will drive the second rotating shaft 9 to start rotating, and the second rotating shaft 9 will drive the second gear body 10 to rotate. The second gear body 10 is meshed with the second gear groove 11, and the second gear body 10 drives the loading platform 2 to translate left and right. At this time, the position translation of the loading platform 2 drives the laser signal transmitter 14 to translate. When the loading platform 2 translates to the accurate position, the laser signal receiver 15 receives the laser signal emitted by the laser signal transmitter 14. The laser signal receiver 15 transmits the laser signal data to the PLC controller 23. The PLC controller 23 controls the first drive motor 4 and the second drive motor 8 to stop moving. At this time, it means that the integrated shell fixing device 16 and the rotor positioning device 17 have been aligned to improve the assembly accuracy of the motor rotor.

[0026] like Figure 1-Figure 3 and Figure 6 As shown, limit grooves 13 are respectively provided on the left and right sides of the inner wall of the adjusting platform 1, and limit blocks 12 are respectively fixed on the left and right sides of the loading platform 2, and the limit blocks 12 are slidably arranged with the limit grooves 13. Support rods 20 are respectively fixed at the four corner positions of the bottom surface of the rotor fixing cover 3, and a base 21 is arranged below the rotor fixing cover 3. The bottom ends of the support rods 20 are respectively fixed to the four corner positions of the top surface of the base 21, and a plurality of air pump lifting columns 22 are fixed to the top surface of the base 21. The telescopic ends of the air pump lifting columns 22 are fixed to the bottom surface of the adjusting platform 1, and a PLC controller 23 is fixed to the front side of the base 21. The laser signal transmitter 14, the laser signal receiver 15, the first drive motor 4, the second drive motor 8 and the air pump lifting column 22 are all electrically connected to the PLC controller 23.

[0027] During use, since the limit groove 13 slides to control the limit block 12, the loading platform 2 connected to the limit block 12 can only move horizontally but cannot move up and down. The staff fixes the rotor on the rotor positioning device 17 and the integrated shell on the integrated shell fixing device 16. The staff turns on the PLC controller 23. At this time, the air pump lifting column 22 starts to rise, and the air pump lifting column 22 pushes the adjusting platform 1 to rise. The adjusting platform 1 drives the loading platform 2 to move upward through the first rotating shaft 5 and the synchronous gear 6. The loading platform 2 will rise with the integrated shell. When it rises to a fixed position, the integrated shell and the rotor are firmly docked and assembled to form an electric drive assembly.

[0028] After the assembly is completed, the rotor positioning device 17 will be separated from the electric drive assembly, and the staff will turn off the PLC controller 23. At this time, the air pump lifting column 22 starts to move downward. When the adjustment platform 1 moves down to the lowest point, the staff can unload the assembled electric drive assembly from the loading platform 2.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
