[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1 - 4 , a press-fitting device for processing motor rotor bearings, including a base 1, and further including:

[0026] A press-fitting assembly, the press-fitting assembly includes legs 2, a top plate 3, a lifter 4, a mounting plate 5 and a thimble 6. The legs 2 are arranged at the four corners above the base 1. The four corners below the top plate 3 are connected to the legs 2. The output end of the lifter 4 penetrates through the top plate 3 and is connected to the mounting plate 5. A thimble 6 is further arranged below the mounting plate 5;

[0027] A bearing assembly, the bearing assembly includes support rods 7, sleeves 8 and a carrier plate 9. Four groups of uniformly arranged support rods 7 are further arranged above the base 1. Sleeves 8 inserted into the support rods 7 are arranged at the four corners below the carrier plate 9. A U-shaped opening is arranged on the carrier plate 9;

[0028] The base 1 provides stable support for the legs 2 and the support rods 7. The bearing assembly is mainly used to carry and position the motor rotor to be press-fitted. The sleeves 8 at the four corners below the carrier plate 9 are inserted into the uniformly arranged support rods 7 above the base 1 to realize the preliminary installation of the carrier plate 9. A limiting assembly for carrying the rotor bearing is further arranged on the carrier plate 9 to stably carry the rotor bearing, so that the rotor bearing and the rotor are arranged in concentric circles. According to the specifications of the rotor bearing to be press-fitted, a suitable thimble 6 is selected and installed on the mounting plate 5. Start the lifter 4, and the output end of the lifter 4 expands and contracts, driving the mounting plate 5 and the thimble 6 to move up and down. When the carrier plate 9 is installed and the rotor bearing to be press-fitted is placed, the lifter 4 drives the thimble 6 to descend, and the thimble 6 applies pressure to the rotor bearing to press-fit the bearing onto the motor rotor. After the press-fitting is completed, the lifter 4 drives the thimble 6 to rise and leave the rotor bearing.

[0029] A crossbeam 10 is provided between two sets of support rods 7 on the same side (left or right), which is adapted to the notch on the pipe sleeve 8, providing lateral positioning and support for the bearing plate 9. The connecting plates 11 on the left and right sides below the bearing plate 9 are connected to the crossbeam 10 through fixing components, further enhancing the stability of the bearing plate 9.

[0030] When the fixing component adopts a combination of a support frame 12, a screw 13, a bearing body 14, a guide rod 15, and a pin block 16, turning the operating handle 17 rotates the screw 13. Since the screw 13 is threadedly connected to the support frame 12, the rotation of the screw 13 drives the connected bearing body 14 and pin block 16 to move smoothly along the side wall of the support frame 12 under the limitation of the guide rod 15. When the pin block 16 moves to the pin slot and pin hole positions of the connecting plate 11, it is inserted therein, thus firmly fixing the bearing plate 9 on the crossbeam 10. When disassembling, rotate the screw 13 in the reverse direction to disengage the pin block 16 from the connecting plate 11, and then the bearing plate 9 can be removed.

[0031] When the fixing component has a structure of a surrounding plate 18 and a centering beam 19, the surrounding plate 18 is U-shaped, and several groups of centering beams 19 arranged on its three sides can support and center the rotor bearing placed on the bearing plate 9. By replacing the bearing plate with corresponding specifications of limit components and U-shaped openings, different specifications of rotor bearings and rotors can be adapted to ensure accurate positioning of the material on the bearing plate 9;

[0032] It should be noted here that the U-shaped openings are concentrically arranged with the arc part of the U-shaped surrounding plate 18. The bearing plate 9 can be set in three groups, and several groups of bearing plates 9 enclose an intermediate frame concentrically arranged with the arc center of the U-shaped opening at the end far from the surrounding plate 18 for bearing the rotor bearing. At this time, the motor rotor can be inserted from the front of the bearing plate 9 and the surrounding plate 18, and the rotor bearing cooperates with the center frame and the motor rotor to complete stable positioning, facilitating subsequent press-fitting.

[0033] As used herein, reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The term "embodiment" that appears in various positions in the specification does not necessarily refer to the same embodiment, nor is it particularly limited to its independence or relevance to other embodiments. In principle, in the present application, as long as there is no technical contradiction or conflict, the technical features mentioned in each embodiment can be combined in any way to form corresponding implementable technical solutions.

[0034] Unless otherwise defined, the meanings of the technical terms used herein are the same as those commonly understood by those skilled in the technical field to which the present application belongs; the use of the relevant terms herein is only for describing specific embodiments and is not intended to limit the present application.
