Description

Technical Field

[0001] The utility model relates to a magnet installation tool. Background Art

[0002] In a motor, magnets need to be installed inside it. The performance of the motor is usually limited by the magnetic flux density of the magnets. As a common situation, the flux density can be increased by using magnets formed of materials with a higher magnetic energy density or a larger thickness, or by installing a magnet assembly / component with a larger flux density. Such a magnet assembly / component is generally formed by bonding multiple magnets in a specific order. Since the magnets need to be installed at specific positions on the inner wall of the motor, and the motor is an integral whole and the inner wall cannot be unfolded and the inner wall space is limited, it is very troublesome to install magnets on the inner wall of the motor.

[0003] The utility model provides a magnet installation tool to achieve efficient and convenient installation of magnets on the inner wall of the motor. Summary of the Utility Model

[0027] 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 making creative efforts belong to the scope of protection of the present invention.

[0028] Embodiment 1, referring to Attached Figure 1 ~Attached Figure 5 .

[0029] This embodiment provides a magnet installation tool. The tool 10 is used to install a magnet 99 inside a motor 20. As shown in Attached Figure 1 , Attached Figure 2 , at least a part of the tool 10 can extend into the motor 20 to install the magnet 99 at a specified position inside the motor 20. The tool includes:

[0030] A floating mechanism 30, the floating mechanism 30 includes a limit post 31 and a bottom plate 32 that can move relative to the limit post 31. The bottom plate 32 can be used to adsorb the magnet 99; referring to Attached 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 less 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.

[0031] A moving member 40, the moving member 40 is a member that drives the bottom plate 32 to move. The moving member 40 is configured to drive the bottom plate 32 to move relative to the limit post 31, and also drive the bottom plate 32 to move relative to the inner wall of the motor 20.

[0032] Preferably, the tool 10 further includes a pressing member 50 configured to drive the magnet 99 to move on the base plate 32. The pressing member 50 makes the installation of the magnet more convenient. Without the pressing member 50, each time the magnet 99 is installed, the base plate 32 needs to be taken out of the interior of the motor 20, and then the magnet 99 is adsorbed on the base plate 32 and inserted back into the interior of the motor 20, as shown in the attached Figure 3 figure. With the pressing member 50, as shown in the attached Figure 1 figure, the magnet 99 can be adsorbed at one end of the base plate 32 (such as position A in the attached Figure 1 and attached Figure 5 figures). By driving the pressing member 50 to drive the magnet 99 to move on the base plate 32, the magnet 99 can be moved to a specified position for installation. Due to the mutual force between different magnets, during the actual installation of magnets inside the motor, usually multiple groups of magnets are loaded into the motor multiple times, rather than being arranged on the base plate 32 all at once 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 does not require frequent disassembly and assembly of the base plate 32.

[0033] It should be noted that the magnet 99 here is a broad concept, including a single magnet or a component formed by two or more magnets.

[0034] Preferably, the pressing member 50 includes a push rod 51 that can move relative to the base plate 32. In order to prevent the push rod 51 from generating new movement due to the force between the magnets 99 after driving the magnet 99 to move. Therefore, a push rod 51 with a self-locking function is preferably used. Further, the pressing member 50 includes an end plate 52 and a push rod 51 that is rotatably screwed on the end plate 52, and the thread between the push rod 51 and the end plate 52 can achieve self-locking.

[0035] Preferably, the end plate 52 is detachably connected to the limit post 31 for convenient disassembly.

[0036] To improve the magnet installation efficiency, preferably, there are two sets of floating mechanisms 30, and the two sets of floating mechanisms 30 are symmetrically arranged. Correspondingly, there are two sets of moving members 40, which are respectively used to drive the two sets of floating mechanisms 30 to move. This can enable the magnet installation tool in this embodiment to install two sets of magnets inside the motor 20 at one time, greatly improving the magnet installation efficiency.

[0037] Preferably, the base plate 32 is in a long strip shape, and the long strip-shaped base plate 32 is convenient for the installation of the magnet. Further, the length of the base plate 32 is greater than the length of the position for installing the magnet inside the motor 20.

[0038] Preferably, since the bottom plate 32 is in a long strip shape and is movable at the same time, in order to ensure the reliability of the bottom plate 32 during movement, one bottom plate 32 is equipped with two moving components 40, and the two moving components 40 are respectively located at two different positions along the length direction of the bottom plate 32, ensuring that both ends of the bottom plate 32 can move in coordination during movement.

[0039] Preferably, referring to the attached Figure 3 , the magnet installation tool further includes a driving component 60. A first inclined surface 61 is formed on the driving component 60, and a second inclined surface 41 is formed on the moving component 40. The first inclined surface 61 is in contact 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 fitted 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 fixture on the market. Since the existing technology is adopted, this structure is not shown in the attached Figure 3 figure.

[0040] Preferably, the driving component 60 is connected with a screw rod 62. The rotation of the screw rod 62 can drive the movement of the driving component 60, and the movement of the driving component 60 will drive the movement of the moving component 40, 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 towards each other or away from each other. The upper and lower OK fixtures are installed in opposite directions. The movement of the two driving components 60 can drive the two bottom plates 32 to move synchronously, realizing the installation of two groups of magnets inside the motor 20 at one time.

[0041] Preferably, the magnet installation tool further includes a positioning seat 70. The positioning seat 70 can provide a positioning surface 73 for supporting the magnet. The positioning surface 73 can be used for supporting when installing the magnet in the motor 20. Referring to the attached Figure 5 figure. Further, the positioning surface 73 is matched with the lowest position in the motor 20 where the magnet can be installed. After the pressing component 50 pushes the magnet to contact the positioning surface 73, the magnet cannot move downward any further. At this time, driving the bottom plate 32, the magnet can be exactly installed at the lowest position.

[0042] Preferably, the positioning seat 70 is detachably connected to the limiting column 31. The positioning seat 70 can be assembled with the motor. By assembling the positioning seat 70 with the motor 20, the positioning of the magnet installation tool can be realized, ensuring that the magnet installation tool can accurately install the magnet to the specified position.

[0043] Preferably, the positioning seat 70 is provided with a positioning hole 71, and the motor is provided with a mounting hole 22. The positioning hole 71 can be connected with the mounting hole 22. Further, the positioning seat 70 is provided with a flange portion 72, and the positioning holes 71 are arranged in a circumferential array on the flange portion 72.

[0044] Preferably, when the positioning seat 70 is assembled with the motor 20, refer to the attached Figure 1 , one 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. To prevent the magnet from shifting on the bottom plate 32, the magnet installation tool further includes a limit card slot 33 located at one end of the bottom plate 32 that extends out of the motor 20. The size of the limit card slot 33 matches that of the magnet, which can prevent the magnet from shifting, especially from shifting during the process of the pressing member 50 driving the magnet to move downward. When the magnet moves downward and enters the interior of the motor 20, the limit card slot 33 is no longer needed at this time because the interior of the motor 20 is provided with protrusions 21 for limiting the magnet. The protrusions 21 inside the motor 20 are usually distributed regularly, such as in a circumferential array distribution.

[0045] Preferably, the limit card slot 33 includes two baffle plates 34 located on both sides of the bottom plate 32. In this embodiment, the size of the limit card slot 33 (the distance between the two baffle plates 34) matches the length of the magnet.

[0046] The ejector rod 51 and the screw rod 62 in this embodiment can be manual or electric.

[0047] Embodiment 2, refer to the attached Figure 1 ~the attached Figure 5 .

[0048] For those skilled in the art to better understand how to use the magnet installation tool for magnet installation, the magnet installation method (the usage method of the magnet installation tool) is now described:

[0049] 1. Fix the positioning seat 70 to the motor 20. Specifically, refer to the attached Figure 4 , the positioning hole 71 on the positioning seat 70 can be connected to the installation hole 22 on the motor using bolts to achieve fixation.

[0050] 2. Assemble the magnet installation tool into a whole. Specifically, refer to the attached Figure 3 , at this time, the limit post 31 is initially installed on the positioning seat 70, and the limit post 31 installed on the positioning seat 70 is connected to the end plate 52 using bolts; alternatively, when the limit post 31 is initially installed on the end plate 52, the limit post 31 installed on the end plate 52 is connected to the positioning seat 70 using bolts;

[0051] 3. Place the magnet at the position of the limit card slot 33, and the magnet is adsorbed on the bottom plate 32. Specifically, place the magnet horizontally in the length direction between the two baffle plates 34, and the magnet is adsorbed on the bottom plate 32 and is limited by the limit card slot 33 at the same time;

[0052] 4. Apply glue to the positions where the magnets need to be bonded. Specifically, it includes at least position B on the drawing (the side of the magnet facing the inner wall of the motor 20). In some cases, such as when the next set of magnets needs to be installed after the current set of magnets is installed, glue needs to be applied to the top of the current set of magnets at this time 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.

[0053] 5. Drive the pressing component 50 to drive the magnet to move on the bottom plate 32 to the specified position. Specifically, the specified position refers to the position inside the motor where the magnet needs to be pasted. Usually, when using the magnet installation tool of the present invention to install the magnet, the installation is carried out in a bottom-up order. Refer to the attached Figure 5 , that is, first install the magnet at position C at the bottom inside the motor 20, gradually install upward, and finally install the magnet at position D at the top inside the motor. Therefore, the specified position here depends on the actual installation situation.

[0054] 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, drive the driving component 60 to move by driving the screw rod 62. The driving component 60 drives the moving component 40 to move, and the moving component 40 drives the magnet on the bottom plate 32 to stick to the inner wall of the motor 20.

[0055] 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 3 , only as a specific installation method, install and fix the limit post 31 between the positioning seat 70 and the end plate 52, and other components can be assembled in advance.

[0056] In step 6, the method adopted in this embodiment is: drive the screw rod 62 to control the movement of the moving component 40.

[0057] In order to fully install the space between two adjacent rows of protrusions 21 inside the motor 20 with magnets, there are two installation methods, which are respectively:

[0058] Method 1, further includes:

[0059] 7. Drive the moving component 40 to reset, and drive the pressing component 50 to reset. Specifically, in the present invention, the moving component 40 and the pressing component 50 reverse.

[0060] Repeat steps 3 to 7 until all the magnets are installed.

[0061] Method 2, between step 5 and step 6, further includes:

[0062] X. Drive the pressing member 50 to reset, and repeat steps 3 to X until all the magnets are set on the bottom plate 32.

[0063] In this embodiment, when the space between two adjacent columns 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 of the positioning seat 70 and the motor 20 (remove the bolt 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 no magnet is installed, and then fix the positioning seat 70 and the motor 20 again (reconnect the bolt 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, then control the positioning seat 70 to rotate, drive the bottom plate 32 to face an area where no magnet is installed, and re-execute the above steps.

[0064] Other implementation manners of this embodiment are the same as those of Embodiment 1.

[0065] The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
