Description

Technical Field

[0001] The utility model belongs to the technical field of motors, and in particular relates to a motor magnetic ring pressing tool. Background Art

[0002] In the field of brushless motors, the magnetic ring is a permanent magnet that is fixedly connected to the rotor. When the magnetic ring and the rotor are installed in the motor, the stator of the motor is energized to generate a magnetic field, which causes the magnetic ring to rotate the rotor under the magnetic force. When installing the magnetic ring, the rotor must be fixed first, and then the magnetic ring must be pressed into the iron core of the rotor.

[0003] The Chinese patent application number 2022220279243 discloses a magnetic ring pressing mechanism for a motor, wherein the motor includes a positioning pin, and the magnetic ring pressing mechanism includes a frame, a jig, an elastic element, and a lifting pressure head; a vertical pin hole is provided on the jig, and the elastic element is arranged in the pin hole, and the lifting pressure head can move vertically and is arranged above the jig; a clearance hole for making way for the positioning pin is provided on the lifting pressure head. The beneficial effect of this scheme is that the deformation and elastic force of the elastic element give the positioning pin a buffering stroke for moving downward, so that the pressure on the positioning pin is buffered, thereby buffering the radial force component, and the radial force component is not easy to reach the critical value that causes the positioning pin to break.

[0004] The above patent solution has the effect of protecting the rotor mounting seat, but during the installation process, the rotor cannot maintain precise stability and the position of the rotor may still shift, which can easily cause damage to the rotor during the downward pressure of the pressure head.

[0024] like Figure 1-3As shown, a motor magnetic ring pressing tool comprises a base plate 1, a fixing device and a clamping device, wherein the fixing device comprises a mounting seat arranged in the middle of the base plate 1 and a clamping mechanism arranged around the mounting seat. The mounting seat comprises a fixed base 6 and an annular seat 7 fixed on the fixed base 6, and a rod groove 8 is provided on the annular seat 7 and the fixed base 6, and the rod groove 8 is used to install the rod part of the rotor. The rod part of the rotor is placed in the rod groove 8 to achieve preliminary positioning of the rotor. Elastic telescopic rods 9 are provided on both sides of the inner side of the annular seat 7, and elastic fixing blocks 10 are provided at the ends of the elastic telescopic rods 9. The design of the mounting seat, especially the rod groove 8 on the annular seat 7 and the fixed base 6, can accurately install and position the rotor. By placing the rod part of the rotor in the rod groove 8, the stability and accuracy of the rotor during the pressing process can be ensured, thereby improving work efficiency and product quality. The design of the elastic telescopic rod 9 and the elastic fixing block 10 on the inner side of the annular seat 7 enables the mounting seat to adapt to rotors of different sizes or shapes. This flexible design not only enhances the flexibility of installation, but also enables the tooling to be applicable to various types of rotors, improving its versatility and scope of use.

[0025] Combination Figure 6 The elastic telescopic rod 9 includes an outer rod 17 and an inner rod 18. The inner rod 18 is slidably arranged inside the outer rod 17. The front end of the inner rod 18 is connected to the elastic fixing block 10. A second buffer spring 19 is connected between the elastic fixing block 10 and the outer rod 17. The top of the elastic fixing block 10 is provided with an inclined smooth surface 20. The top is provided with an inclined smooth surface 20. This design enables the rotor to slide into the predetermined position more easily when pressed in. The inclined smooth surface 20 not only reduces the difficulty of operation, but also improves the accuracy and stability of positioning. At the same time, the contact surface between the elastic fixing block 10 and the rotor rod is more fitted, further enhancing the stability of positioning. The elastic telescopic rod 9 consists of an outer rod 17 and an inner rod 18. The inner rod 18 can slide inside the outer rod 17. This design enables the length of the telescopic rod to be adjusted as needed. This flexibility enables the tooling to adapt to rotors with rods of different diameters, enhancing its applicability and versatility. The second buffer spring 19 connected between the elastic fixing block 10 and the outer rod 17 plays a role of buffering and protection. During the process of pressing the rotor into place, the spring can absorb and reduce the impact force to prevent the rotor or tooling from being damaged. This buffer mechanism helps to protect the rotor and tooling and extend their service life. The design of the elastic telescopic rod 9 and the elastic fixing block 10 allows the operator to fix the rotor on the mounting seat more conveniently. Without complicated operation or adjustment, fast and accurate positioning can be achieved, which improves work efficiency.

[0026] Combination Figure 1 and Figure 3The clamping mechanism includes a first electric telescopic rod 11, a second electric telescopic rod 12 and a third electric telescopic rod 13. The first electric telescopic rod 11, the second electric telescopic rod 12 and the third electric telescopic rod 13 are spaced at the same angle. The front ends of the first electric telescopic rod 11, the second electric telescopic rod 12 and the third electric telescopic rod 13 are connected to an output rod 14, and the front end of the output rod 14 is connected to a clamping plate 15. Since the first electric telescopic rod 11, the second electric telescopic rod 12 and the third electric telescopic rod 13 are spaced at the same angle, they can evenly apply force to the clamping plate 15, thereby achieving even clamping of the rotor. This even clamping helps prevent the rotor from shifting or deforming during the pressing process, thereby improving the stability and accuracy of the pressing process. Combined with Figure 4 and Figure 5 A first buffer spring 16 is also connected between the output rod 14 and the clamping plate 15. When the clamping mechanism is working, the first buffer spring 16 can absorb and reduce the impact force generated during the clamping process to prevent damage to the rotor core due to excessive force suddenly applied. This buffer mechanism helps to protect the integrity of the rotor structure and extend its service life.

[0027] Combination Figure 1 The clamping device includes a support column 2 fixed on a base plate 1, a support plate 3 is provided on the top of the support column 2, a clamping cylinder 4 is provided in the middle of the support plate 3, the clamping cylinder 4 extends downward and is connected to a clamping head 5, and the arrangement of the clamping cylinder 4 and the clamping head 5 can accurately control the position and force of the magnetic ring pressing in, thereby ensuring the accuracy and consistency of the pressing process.

[0028] This embodiment can effectively clamp and position the rod portion of the rotor through the design of the mounting seat, especially the elastic telescopic rod 9 and the elastic fixing block 10 inside the annular seat 7, thereby ensuring the stability of the rotor during the pressing process.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
