[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Example 1, refer to the attached Figure 1 ~Attached Figure 5 .

[0043] This embodiment provides a magnet installation tool, the tool 10 is used to install a magnet 99 inside a motor 20, as shown in the attached Figure 1 , Attachment Figure 2 As shown, at least a portion of the tool 10 can be inserted into the motor 20 to install the magnet 99 at a specified position inside the motor 20. The tool includes:

[0044] The floating mechanism 30 includes a limit column 31 and a bottom plate 32 that can move relative to the limit column 31, and the bottom plate 32 can be used to attract the magnet 99; Figure 5 By controlling the movement of the bottom plate 32 in the floating mechanism 30, the magnet 99 adsorbed thereon can be driven to move together. The maximum suction force that can be generated between the bottom plate 32 and the magnet 99 is smaller than the maximum suction force that can be generated between the magnet 99 and the inner wall of the motor 20. Therefore, when the bottom plate 32 is close enough to the inner wall of the motor 20, the magnet 99 will be adsorbed to the inner wall of the motor 20, thereby realizing the transfer of the magnet 99 from the bottom plate 32 to the inner wall of the motor 20.

[0045] The moving component 40 is a component that drives the bottom plate 32 to move. The moving component 40 is configured to drive the bottom plate 32 to move relative to the limiting column 31 and also to drive the bottom plate 32 to move relative to the inner wall of the motor 20 .

[0046] Preferably, the tool 10 further includes a pressing component 50, which is configured to drive the magnet 99 to move on the bottom plate 32. The pressing component 50 makes it easier to install the magnet. If the pressing component 50 is not present, each time the magnet 99 is installed, the bottom plate 32 needs to be removed from the inside of the motor 20, the magnet 99 needs to be adsorbed on the bottom plate 32, and then inserted back into the inside of the motor 20. Figure 3 As shown. After the pressing component 50 is provided, as shown in the attached Figure 1 As shown, the magnet 99 can be adsorbed on one end of the bottom plate 32 (as shown in the attached Figure 1 , Attachment Figure 5The pressing member 50 is driven to move the magnet 99 on the bottom plate 32, so that the magnet 99 moves to the designated position for installation. Due to the interaction between different magnets, during the actual installation of magnets inside the motor, the magnets are usually installed into the motor in multiple groups and multiple times, rather than all arranged on the bottom plate 32 at one time and installed in place at one time. Therefore, the setting of the pressing member 50 can greatly improve the installation efficiency of the magnet inside the motor, and there is no need to frequently disassemble and assemble the bottom plate 32.

[0047] It should be noted that the magnet 99 here is a broad concept, including one magnet or an assembly formed by two or more magnets.

[0048] Preferably, the pressing component 50 includes a push rod 51 that can move relative to the bottom plate 32, so that the push rod 51 will not generate new movement due to the force between the magnets 99 after the magnet 99 is driven to move. Therefore, the push rod 51 with a self-locking function is preferred. Further, the pressing component 50 includes an end plate 52 and a push rod 51 that is installed on the end plate 52 and can be spirally rotated, and the thread between the push rod 51 and the end plate 52 can achieve self-locking.

[0049] Preferably, the end plate 52 is detachably connected to the limiting column 31 to facilitate disassembly.

[0050] In order to improve the magnet installation efficiency, preferably, two groups of floating mechanisms 30 are provided, and the two groups of floating mechanisms 30 are symmetrically arranged. Correspondingly, two groups of moving parts 40 are provided, which are respectively used to drive the two groups of floating mechanisms 30 to move. In this way, the magnet installation tool of this embodiment can install two groups of magnets inside the motor 20 at a time, which greatly improves the magnet installation efficiency.

[0051] Preferably, the bottom plate 32 is in the shape of an elongated strip, and the elongated bottom plate 32 is convenient for installing the magnet. Further, the length of the bottom plate 32 is greater than the length of the position where the magnet is installed in the motor 20.

[0052] Preferably, since the bottom plate 32 is in the shape of an elongated strip and is movable, in order to ensure the reliability of the bottom plate 32 during movement, one bottom plate 32 is equipped with two moving parts 40, and the two moving parts 40 are respectively located at two different positions in the extension direction of the bottom plate 32, ensuring that the two ends can move in coordination when the bottom plate 32 moves.

[0053] Preferably, see Attachment Figure 3The magnet installation tool also includes a driving component 60, which is configured with a first inclined surface 61, and a second inclined surface 41 is configured on the moving component 40. The first inclined surface 61 fits with the second inclined surface 41, so that the longitudinal movement of the driving component 60 can be converted into the lateral movement of the moving component 40. In addition, the driving component 60 and the moving component 40 are partially embedded together to ensure that the driving component 60 and the moving component 40 are always linked. The design of the driving component 60 and the moving component 40 can refer to the common OK clamps on the market. Since the existing technology is adopted, the structure is attached Figure 3 Not shown in the figure.

[0054] Preferably, the driving component 60 is connected to a screw rod 62, and the rotation of the screw rod 62 can drive the driving component 60 to move, and the movement of the driving component 60 can drive the moving component 40 to move, thereby realizing the control of the bottom plate 32 in the floating mechanism 30. In this embodiment, the screw rod 62 can drive the two driving components 60 to move toward each other or away from each other, and the upper and lower OK clamps are installed in opposite directions. The movement of the two driving components 60 can drive the two bottom plates 32 to move synchronously, thereby realizing the installation of two sets of magnets inside the motor 20 at a single time.

[0055] Preferably, the magnet installation tool further comprises a positioning seat 70, and the positioning seat 70 can provide a positioning surface 73 for supporting the magnet, and the positioning surface 73 can be used to support the magnet when it is installed in the motor 20. Figure 5 Further, the positioning surface 73 matches the lowest position where the magnet can be installed in the motor 20, and after the pressing component 50 pushes the magnet to contact the positioning surface 73, the magnet cannot continue to move downward, and the bottom plate 32 is driven at this time, and the magnet can be installed just at the lowest position.

[0056] Preferably, the positioning seat 70 is detachably connected to the limiting column 31, and the positioning seat 70 can be assembled with the motor. By assembling the positioning seat 70 and the motor 20 together, the positioning of the magnet installation tool can be achieved, ensuring that the magnet installation tool can accurately install the magnet to the specified position.

[0057] Preferably, the positioning seat 70 is provided with a positioning hole 71, the motor is provided with a mounting hole 22, and the positioning hole 71 can be connected to the mounting hole 22. Further, the positioning seat 70 is provided with a flange portion 72, and the positioning holes 71 are located on the flange portion 72 and distributed in a circumferential array.

[0058] Preferably, when the positioning seat 70 and the motor 20 are assembled together, refer to the attached Figure 1One end of the bottom plate 32 extends out of the motor 20, which is convenient for the operator to place the magnet on the bottom plate 32. In order to prevent the magnet from shifting on the bottom plate 32, the magnet installation tool also includes a limit slot 33 located at one end of the bottom plate 32 extending out of the motor 20. The size of the limit slot 33 matches the magnet, which can prevent the magnet from shifting, especially preventing the magnet from shifting during the downward movement of the pressing component 50. When the magnet moves down and enters the interior of the motor 20, the limit slot 33 is no longer needed because the motor 20 has a protrusion 21 inside for limiting the magnet, and the protrusions 21 inside the motor 20 are usually distributed in a certain regular pattern, such as a circular array distribution.

[0059] Preferably, the limiting slot 33 includes two baffles 34 located on both sides of the bottom plate 32. In this embodiment, the size of the limiting slot 33 (the distance between the two baffles 34) matches the length of the magnet.

[0060] The push rod 51 and the screw rod 62 in this embodiment can be manual or electric.

[0061] Example 2, refer to the attached Figure 1 ~Attached Figure 5 .

[0062] In order for those skilled in the art to better understand how to use the magnet installation tool to install the magnet, the installation method of the magnet (the method of using the magnet installation tool) is now described:

[0063] 1. Fix the positioning seat 70 and the motor 20. For details, please refer to the attached Figure 4 The positioning hole 71 on the positioning seat 70 can be connected to the mounting hole 22 on the motor by using bolts to achieve fixation.

[0064] 2. Assemble the magnet installation tool into a whole. For details, please refer to the attached Figure 3 At this time, the limiting column 31 is initially installed on the positioning seat 70, and the limiting column 31 installed on the positioning seat 70 is connected to the end plate 52 by bolts; or, when the limiting column 31 is initially installed on the end plate 52, the limiting column 31 installed on the end plate 52 is connected to the positioning seat 70 by bolts;

[0065] 3. Place the magnet in the position of the limit slot 33, and the magnet is adsorbed on the bottom plate 32. Specifically, the length direction of the magnet is horizontally placed between the two baffles 34, and the magnet is adsorbed on the bottom plate 32 and is limited by the limit slot 33;

[0066] 4. Apply glue to the positions where the magnets need to be bonded, specifically, at least including the position B in the figure (the side where the magnets face the inner wall of the motor 20). In some cases, if the next set of magnets needs to be installed after the installation of the current set of magnets is completed, glue needs to be applied to the top of the current set of magnets to facilitate bonding between the current set of magnets and the next set of magnets. Of course, glue can also be applied to the bottom of the next set of magnets;

[0067] 5. The pressing component 50 is driven to move the magnet to the designated position on the bottom plate 32. Specifically, the designated position refers to the position inside the motor where the magnet needs to be attached. Usually, when the magnet installation tool of the present invention is used to install the magnet, the order from bottom to top is adopted. Figure 5 , that is, first install the magnet at the bottom C position in the motor 20, gradually install it upward, and finally install the magnet at the top D position in the motor, so the designated position here depends on the actual installation situation;

[0068] 6. Drive the moving component 40 to drive the magnet on the bottom plate 32 to stick to the inner wall of the motor 20. Specifically, the driving component 60 is driven to move by driving the screw 62, and the driving component 60 drives the moving component 40 to move. The moving component 40 drives the magnet on the bottom plate 32 to stick to the inner wall of the motor 20.

[0069] In order to install the magnet installation tool into the motor 20, in step 2, the magnet installation tool needs to be assembled into a whole. Usually, the two parts of the magnet installation tool are assembled into a whole, as shown in the attached figure. Figure 3 The figure is only used as a specific installation method, in which the limiting column 31 between the positioning seat 70 and the end plate 52 is installed and fixed, and other components can be assembled first.

[0070] In step 6, the method adopted in this embodiment is: driving the screw rod 62 to control the movement of the moving component 40.

[0071] In order to completely install magnets in the space between two adjacent rows of protrusions 21 in the motor 20, there are two installation methods, namely:

[0072] Method 1 also includes:

[0073] 7. The driving moving component 40 is reset, and the driving pressing component 50 is reset. Specifically, in the present invention, the driving moving component 40 and the pressing component 50 are reversed;

[0074] Repeat steps 3 to 7 until all magnets are installed.

[0075] Method 2: between step 5 and step 6, the following is also included:

[0076] X. Drive the pressing component 50 to reset, and repeat steps 3 to X until all magnets are set on the bottom plate 32.

[0077] In this embodiment, when the space between two adjacent rows of protrusions 21 is fully installed with magnets, it is necessary to install magnets at other positions. At this time, the operator can first cancel the fixation between the positioning seat 70 and the motor 20 (remove the bolts between the positioning hole 71 and the mounting hole 22), rotate the positioning seat 70 so that the bottom plate 32 faces an area where magnets are not installed, and re-fix the positioning seat 70 and the motor 20 (re-connect the bolts between the positioning hole 71 and the mounting hole 22). In other embodiments, if the flange portion 72 of the positioning seat 70 is rotatable, the positioning seat 70 is controlled to rotate, driving the bottom plate 32 to face an area where magnets are not installed, and re-perform the above steps.

[0078] The other implementations of this embodiment are the same as those of Embodiment 1.

[0079] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
