Abstract

Technical Field
[0001] This invention relates to a magnet mounting tool and a magnet mounting method. Background Technology
[0002] In an electric motor, magnets need to be installed inside. The performance of the motor is usually limited by the flux density of the magnets. As a common practice, the flux density can be increased by using magnets made of materials with high magnetic energy density or large thickness. Alternatively, magnet assemblies / components with large flux density can be installed. These magnet assemblies / components are generally made of multiple magnets bonded together in a specific order. Since the magnets need to be installed in specific positions on the inner wall of the motor, and the motor is a whole, the inner wall cannot be unfolded, and the inner wall space is limited, so installing magnets on the inner wall of the motor is very troublesome.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0042] Example 1, refer to Appendix Figure 1 ~Attached Figure 5 .
[0043] This embodiment provides a magnet mounting tool. Tool 10 is used to mount magnet 99 inside motor 20, as shown in the attached figure. Figure 1 Appendix Figure 2 As shown, at least a portion of the tool 10 can extend into the motor 20 for mounting a magnet 99 at a designated location inside the motor 20. The tool includes:
[0044] The floating mechanism 30 includes a limiting post 31 and a base plate 32 that can move relative to the limiting post 31. The base plate 32 can be used to attract a magnet 99. (See attached diagram) Figure 5 By controlling the movement of the base plate 32 in the floating mechanism 30, the magnet 99 adsorbed on it can be driven to move together. The maximum attraction between the base plate 32 and the magnet 99 is less than the maximum attraction between the magnet 99 and the inner wall of the motor 20. Therefore, when the base plate 32 is close enough to the inner wall of the motor 20, the magnet 99 will be attracted to the inner wall of the motor 20, thereby realizing the transfer of the magnet 99 from the base plate 32 to the inner wall of the motor 20.
[0045] The moving part 40 is a component that drives the base plate 32 to move. The moving part 40 is configured to drive the base plate 32 to move relative to the limiting post 31, and also to drive the base plate 32 to move relative to the inner wall of the motor 20.
[0046] Preferably, tool 10 further includes a pressing component 50, which is configured to move the magnet 99 on the base plate 32. The pressing component 50 makes magnet installation more convenient. Without the pressing component 50, each time the magnet 99 is installed, the base plate 32 needs to be removed from the motor 20, the magnet 99 needs to be attached to the base plate 32, and then it needs to be inserted back into the motor 20. Figure 3 As shown. With the pressing component 50, as attached... Figure 1 As shown, magnet 99 can be attached to one end of base plate 32 (as shown in the attached diagram). Figure 1 Appendix Figure 5Position A in the diagram is used to drive the pressing component 50 to move the magnet 99 on the base plate 32, thereby moving the magnet 99 to the designated position for installation. Due to the interaction forces between different magnets, during the actual installation of magnets inside the motor, magnets are usually installed in multiple groups and in multiple steps, rather than all of them being arranged and installed in one go on the base plate 32. Therefore, the setting of the pressing component 50 can greatly improve the installation efficiency of magnets inside the motor, eliminating the need for frequent disassembly and reassembly of the base plate 32.
[0047] It should be noted that "magnet 99" here is a broad concept, including a single magnet or a component formed by two or more magnets.
[0048] Preferably, the pressing component 50 includes a push rod 51 that can move relative to the base plate 32. To prevent the push rod 51 from generating new movement due to the force between the magnets 99 after it has driven the magnets 99 to move, a 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 helically rotatable and mounted on the end plate 52. The thread between the push rod 51 and the end plate 52 enables self-locking.
[0049] Preferably, the end plate 52 is detachably connected to the limiting post 31, which facilitates disassembly.
[0050] To improve magnet installation efficiency, preferably, the floating mechanism 30 is provided in two sets, symmetrically arranged. Correspondingly, the moving parts 40 are provided in two sets, each used to drive the movement of the two sets of floating mechanisms 30. This allows the magnet installation tool of this embodiment to install two sets of magnets inside the motor 20 in a single operation, greatly improving magnet installation efficiency.
[0051] Preferably, the base plate 32 is elongated, which facilitates the installation of the magnet. Further, the length of the base plate 32 is greater than the length of the area within the motor 20 where the magnet is installed.
[0052] Preferably, since the base plate 32 is elongated and movable, in order to ensure the reliability of the base plate 32 during movement, one base plate 32 is equipped with two moving parts 40. The two moving parts 40 are located at two different positions in the extension direction of the base plate 32, so as to ensure that the two ends of the base plate 32 can move in coordination when it moves.
[0053] Preferred options are shown in the appendix. Figure 3The magnet mounting tool also includes a drive component 60, which has a first inclined surface 61, and a moving component 40 has a second inclined surface 41. The first inclined surface 61 and the second inclined surface 41 are fitted together, so that the longitudinal movement of the drive component 60 can be converted into the lateral movement of the moving component 40. Furthermore, the drive component 60 and the moving component 40 are partially interlocked to ensure that the drive component 60 and the moving component 40 are always linked. The design of the drive component 60 and the moving component 40 can refer to commonly available OK clamps. Since this structure uses existing technology, it has... Figure 3 It is not shown in the text.
[0054] Preferably, the drive component 60 is connected to a screw 62. The rotation of the screw 62 drives the drive component 60 to move, and the movement of the drive component 60 in turn drives the movement of the moving component 40, thereby controlling the base plate 32 in the floating mechanism 30. In this embodiment, the screw 62 can drive the two drive components 60 to move towards each other or away from each other. The upper and lower OK clamps are installed in opposite directions. The movement of the two drive components 60 can drive the two base plates 32 to move synchronously, realizing the installation of two sets of magnets inside the motor 20 at a time.
[0055] Preferably, the magnet mounting tool further includes a positioning base 70, which provides a positioning surface 73 to support the magnet. The positioning surface 73 can be used to support the magnet when it is installed inside the motor 20. (Refer to the attached drawing.) Figure 5 As shown. Further, the positioning surface 73 matches 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 can no longer move downward. At this time, the base plate 32 is driven, and the magnet can be installed in the lowest position.
[0056] Preferably, the positioning seat 70 is detachably connected to the limiting post 31, and 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 achieved, ensuring that the magnet installation tool can accurately install the magnet to the designated position.
[0057] Preferably, the positioning seat 70 is provided with positioning holes 71, and the motor is provided with mounting holes 22, and the positioning holes 71 can be connected to the mounting holes 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 are distributed in a circumferential array.
[0058] Preferably, when the positioning seat 70 is assembled with the motor 20, refer to the attached diagram. Figure 1A motor 20 extends from one end of the base plate 32, making it convenient for operators to place the magnet on the base plate 32. To prevent the magnet from shifting on the base plate 32, the magnet installation tool also includes a limiting slot 33 located at the end of the base plate 32 from which the motor 20 extends. The size of the limiting 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 into the motor 20, the limiting slot 33 is no longer needed, because the motor 20 has a protrusion 21 inside to limit the magnet. The protrusions 21 inside the motor 20 are usually distributed in a certain pattern, such as a circumferential array.
[0059] Preferably, the limiting slot 33 includes two baffles 34 located on both sides of the base 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] In this embodiment, the push rod 51 and screw 62 can be manual or electric.
[0061] Example 2, refer to Appendix Figure 1 ~Attached Figure 5 .
[0062] To help those skilled in the art better understand how to use this magnet mounting tool for magnet mounting, the magnet mounting method (the method of using the magnet mounting tool) is described below:
[0063] 1. Fix the positioning seat 70 to the motor 20. For details, please refer to the attached document. Figure 4 Bolts can be used to connect the positioning hole 71 on the positioning seat 70 with the mounting hole 22 on the motor to achieve fixation.
[0064] 2. Assemble the magnet mounting tool into a complete unit. For details, please refer to the attached document. Figure 3 At this time, the limiting post 31 is initially installed on the positioning seat 70, and the limiting post 31 installed on the positioning seat 70 is connected to the end plate 52 by bolts; or, when the limiting post 31 is initially installed on the end plate 52, the limiting post 31 installed on the end plate 52 is connected to the positioning seat 70 by bolts.
[0065] 3. Place the magnet in the limiting slot 33. The magnet is attracted to the base plate 32. Specifically, place the magnet horizontally between the two baffles 34 along its length. The magnet is attracted to the base plate 32 and is simultaneously limited by the limiting slot 33.
[0066] 4. Apply glue to the areas where the magnets need to be bonded. Specifically, this includes at least position B in the attached diagram (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 to facilitate bonding between the current set of magnets and the next set of magnets. Alternatively, glue can be applied to the bottom of the next set of magnets.
[0067] 5. The driving pressing component 50 moves the magnet on the base plate 32 to a designated position. Specifically, the designated position refers to the location inside the motor where the magnet needs to be attached. Normally, when using the magnet installation tool of this invention to install magnets, a bottom-up sequence is adopted, as shown in the attached diagram. Figure 5 That is, first install the magnet at position C at the bottom inside the motor 20, then install it upwards step by step, 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.
[0068] 6. The driving motion component 40 drives the magnet on the base plate 32 to stick to the inner wall of the motor 20. Specifically, the driving screw 62 drives the driving component 60 to move, the driving component 60 drives the motion component 40 to move, and the motion component 40 drives the magnet on the base plate 32 to stick to the inner wall of the motor 20.
[0069] In order to install the magnet mounting tool into the motor 20, in step 2, the magnet mounting tool needs to be assembled into a whole. Typically, the two parts of the magnet mounting tool are assembled into a single unit, as shown in the attached diagram. Figure 3 The diagram shown is only one specific installation method, in which the limiting post 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, this embodiment uses the following method: drive screw 62 to control the movement of moving part 40.
[0071] To completely fill the space between two adjacent rows of protrusions 21 within the motor 20 with magnets, there are two installation methods:
[0072] Method 1 also includes:
[0073] 7. Drive the moving part 40 to reset, drive the pressing part 50 to reset. Specifically, in this invention, drive the moving part 40 and the pressing part 50 reverse their directions.
[0074] Repeat steps 3 through 7 until all magnets are installed.
[0075] Method 2, between steps 5 and 6, also includes:
[0076] X. Drive the pressing component 50 to reset, and repeat steps 3 to X until all magnets are set on the base plate 32.
[0077] In this embodiment, after the space between two adjacent columns of protrusions 21 is completely filled with magnets, magnets need to be installed in other positions. At this time, the operator can first unfix the positioning seat 70 to the motor 20 (remove the bolts between the positioning hole 71 and the mounting hole 22), rotate the positioning seat 70 so that the base plate 32 faces an area where no magnets are installed, and then fix the positioning seat 70 to the motor 20 again (reconnect the bolts between the positioning hole 71 and the mounting hole 22). In other embodiments, if the flange 72 of the positioning seat 70 is rotatable, the positioning seat 70 is controlled to rotate, causing the base plate 32 to face an area where no magnets are installed, and the above steps are repeated.
[0078] The other implementation methods in this embodiment are the same as in Embodiment 1.
[0079] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
