During assembly and disassembly, the outer rotating permanent magnet is difficult to assemble and disassemble due to its strong magnetic attraction and fragility. This makes it difficult to ensure the parallelism between the outer rotating permanent magnets during installation and can easily damage them. Therefore, designing a convenient and reliable tool for picking up and placing the outer rotating permanent magnet is essential and urgent. Utility Model Content

[0003] The purpose of this invention is to provide a tooling for picking up and placing permanent magnets in a magnetic coupling device, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0010] Preferably, the magnetic shielding sleeve has a mounting post on the outside of one end near the outer magnetic rotor, and a mounting groove that mates with the mounting post is formed inside one end of the outer magnetic rotor. The first guide protrusion and the through groove inside the outer magnetic rotor both protrude inward from the mounting groove.

[0011] Preferably, the magnetically shielded pusher cylinder is provided with a plurality of mounting surfaces for placing the external rotating permanent magnet at one end of the pusher block, one mounting surface corresponds to one pusher block, and grooves are correspondingly opened between adjacent mounting surfaces and adjacent pushers, and the grooves are correspondingly arranged with the first guide protrusion and the second guide protrusion.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example:

[0029] Please see Figures 1-7 As shown, a permanent magnet picking and placing fixture for a magnetic coupling device includes:

[0030] The magnetic push cylinder 7, the magnetic push rod 8, the outer magnetic rotor 1, and the magnetic sleeve 5 spliced ​​with the outer magnetic rotor 1 are slidably connected to the magnetic push cylinder 7, the magnetic sleeve 5, and the outer magnetic rotor 1. Multiple sets of external rotating permanent magnets 6 are installed inside the outer magnetic rotor 1. The multiple sets of external rotating permanent magnets 6 are located on the outer side of one end of the magnetic push cylinder 7. The magnetic push rod 8 can be detachably installed inside the magnetic push cylinder 7.

[0031] refer to Figures 1-6As shown, both the outer magnetic rotor 1 and the magnetic shielding sleeve 5 have through slots that allow the outer rotating permanent magnet 6 to pass through. There are multiple through slots arranged in a circumferential array. The magnetic shielding pusher 7 is provided with multiple push blocks 71 that cooperate with the through slots. The push blocks 71 are slidably connected to the through slots. The outer magnetic rotor 1 is made of magnetic material and has a magnetic attraction function, which can attract the outer rotating permanent magnet 6. During installation, the outer rotating permanent magnet 6 is attracted to the corresponding through slots opened inside the outer magnetic rotor 1.

[0032] refer to Figures 1-6 As shown, the through slot inside the outer magnetic rotor 1 is connected to the through slot inside the magnetic shielding sleeve 5.

[0033] refer to Figures 1-6 As shown, a first guide protrusion is provided between adjacent through slots inside the outer magnetic rotor 1, and a second guide protrusion is provided between adjacent through slots inside the magnetic shielding sleeve 5. The first and second guide protrusions are correspondingly arranged, and both sides of the outer rotating permanent magnet 6 can respectively abut against the side of the nearest first or second guide protrusion located on the corresponding side. It should be noted that the first guide protrusion can protrude inward beyond the second guide protrusion, or it can be arranged in the same way as the second guide protrusion. The second guide protrusion can protrude inward beyond the first guide protrusion, as long as the first and second guide protrusions do not interfere with the movement of the outer rotating permanent magnet 6 and the magnetic shielding push cylinder 7. The through slots, the first guide protrusion, and the second guide protrusion inside the outer magnetic rotor 1 and the magnetic shielding sleeve 5 form a connecting channel that allows the outer rotating permanent magnet 6 and the magnetic shielding push cylinder 7 to pass through.

[0034] Furthermore, when the outer rotating permanent magnet 6 is located in the through slot opened inside the outer magnetic rotor 1, both sides of the outer rotating permanent magnet 6 are respectively attached to the side of the first guide protrusion closest to the corresponding side. When the outer rotating permanent magnet 6 is located in the through slot opened inside the magnetic shielding sleeve 5, both sides of the outer rotating permanent magnet 6 are respectively attached to the side of the second guide protrusion closest to the corresponding side. When the outer rotating permanent magnet 6 is located between the through slot opened inside the outer magnetic rotor 1 and the magnetic shielding sleeve 5, both sides of the outer rotating permanent magnet 6 located in the through slot part inside the outer magnetic rotor 1 are respectively attached to the side of the first guide protrusion closest to the corresponding side, and both sides of the outer rotating permanent magnet 6 located in the through slot part inside the magnetic shielding sleeve 5 are respectively attached to the side of the second guide protrusion closest to the corresponding side.

[0035] refer to Figures 1-6As shown, the magnetic shielding sleeve 5 has a mounting post 51 on the outside of one end near the outer magnetic rotor 1, and a mounting groove 52 that mates with the mounting post 51 is provided inside one end of the outer magnetic rotor 1. The first guide protrusion and the through groove provided inside the outer magnetic rotor 1 both protrude inward from the mounting groove 52, which are used to install the outer magnetic rotor 1 and the magnetic shielding sleeve 5. The magnetic shielding sleeve 5 is made of magnetic shielding material to ensure that when it comes into contact with the outer rotating permanent magnet 6, it will not generate a magnetic attraction force to attract the outer rotating permanent magnet 6 into the through groove opened inside the magnetic shielding sleeve 5.

[0036] refer to Figures 1-6 As shown, the magnetically shielded pusher 7 has multiple mounting surfaces 72 for placing the external rotating permanent magnet 6 at one end of the pusher block 71. Each mounting surface 72 corresponds to one pusher block 71. When the external rotating permanent magnet 6 is placed on the mounting surface 72, one end of the external rotating permanent magnet 6 abuts against the pusher block 71. Grooves are correspondingly opened between adjacent mounting surfaces 72 and adjacent pushers 71. The grooves are correspondingly set with the first guide protrusion and the second guide protrusion, which can effectively prevent interference between the mounting surface 72, the pusher block and the first guide protrusion and the second guide protrusion when the magnetically shielded pusher 7 moves.

[0037] refer to Figures 1-6 As shown, a push rod is provided at the other end of the push block 71 of the magnetically shielded push cylinder 7. The end of the magnetically shielded push cylinder 7 near the push rod has an inwardly formed groove that mates with the magnetically attracted push rod 8. The magnetically attracted push rod 8 is made of magnetic material and can generate a magnetic attraction force on the externally rotating permanent magnet 6, which is beneficial for fixing the externally rotating permanent magnet 6 onto the mounting surface. It should be noted that the magnetically shielded push cylinder 7 is made of magnetically shielded material and will not generate a magnetic attraction force with the externally rotating permanent magnet 6.

[0038] refer to Figures 1-6 As shown, the magnetic pusher cylinder 7 has an exhaust hole at one end near the mounting surface. The exhaust hole is connected to the slot, which can effectively prevent the air in the slot from affecting the installation of the magnetic pusher 8. Specifically, it can prevent the magnetic pusher 8 from not being in contact with the bottom of the slot when it is installed on the magnetic pusher cylinder 7.

[0039] refer to Figures 1-6 As shown, a limiting groove is provided at the end of the outer magnetic rotor 1 away from the magnetic shielding sleeve 5. A limiting component is installed in the limiting groove to limit the outer rotating permanent magnet 6 installed inside the outer magnetic rotor 1. The first guide protrusion and the through groove provided inside the outer magnetic rotor 1 both protrude inward from the limiting groove.

[0040] refer to Figures 1-6As shown, the limiting component includes a top bearing 3, a washer 2, and a top bearing retaining ring 4. The washer 2 is engaged in the limiting groove one near the end of the first guide protrusion. A limiting groove two is also provided on the limiting groove one. The top bearing retaining ring 4 is engaged in the limiting groove two. The top bearing 3 is engaged between the washer 2 and the top bearing retaining ring 4. The installation of the top bearing retaining ring 4 can limit the installation of the washer 2 and the top bearing 3, preventing them from dislodging from the limiting groove two.

[0041] During installation, first, push the magnetic pusher 8 concentrically into the bottom of the slot provided in the magnetic shielding pusher 7. Then, place one side of each of the multiple sets of external rotating permanent magnets 6 against the mounting surface of the magnetic shielding pusher 7. One end of the external rotating permanent magnet 6 abuts against the pusher block 71. The external rotating permanent magnet 6 and the magnetic pusher 8 are attracted by magnetic force, so that each external rotating permanent magnet 6 will not fall off or shift when it is attached to the mounting surface of the magnetic shielding pusher 7. Then, treat the magnetic shielding pusher 7, the magnetic pusher 8, and the multiple sets of external rotating permanent magnets 6 as a whole, and align the external rotating permanent magnets 6 with the through slots opened in the magnetic shielding sleeve 5. Push the magnetic pusher 8 to push the multiple sets of external rotating permanent magnets 6 into the interior of the magnetic shielding sleeve 5. Under the action of the magnetic pusher 8, push the external rotating permanent magnets 6 from the inside of the through slot of the magnetic shielding sleeve 5 into the inside of the through slot of the external magnetic rotor 1 until the end of the external rotating permanent magnet 6 is attached to one end of the washer 2. After installation, the magnetic isolation push cylinder 7 is fixed in place, and the magnetic push rod 8 is removed, so that the multiple sets of external rotating permanent magnets 6 lose the magnetic attraction force generated by the magnetic push rod 8. At the same time, the magnetic attraction force generated by the external magnetic rotor 1 made of magnetic material on the multiple sets of external rotating permanent magnets 6 allows the multiple sets of external rotating permanent magnets 6 to be magnetically attached to the through groove inside the external magnetic rotor 1 without falling off or shifting. Then the magnetic isolation push cylinder 7 is pulled out. At this time, the installation of the multiple sets of external rotating permanent magnets 6 is completed.

[0042] When removing multiple sets of external rotating permanent magnets 6, first remove the top bearing retaining ring 4, top bearing 3, and washer 2 from the interior of the external magnetic rotor 1 in sequence. Then, insert the magnetic isolation pusher 7 into the external magnetic rotor 1 from the end near the limiting groove (e.g., Figure 7 As shown, after aligning the mounting surface of the circumferentially arranged magnetic push cylinder 7 with the multiple sets of external rotating permanent magnets 6 magnetically attached to the inside of the external magnetic rotor 1, the magnetic push cylinder 7 is pushed deeply. This causes the push block 71 of the magnetic push cylinder 7 to push the multiple sets of external rotating permanent magnets 6 from the inside of the external magnetic rotor 1 into the inside of the magnetic shielding sleeve 5, thus removing the external rotating permanent magnets 6 from the inside of the external magnetic rotor 1. It should be noted that when removing the multiple sets of external rotating permanent magnets 6, several external rotating permanent magnets 6 can be directly pushed out by the magnetic push cylinder 7, or the magnetic push rod 8 can be used to push the magnetic push cylinder 7 to move, thereby removing the multiple sets of external rotating permanent magnets 6. Figure 7 As shown.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
