Fig. 1 shows a magnetic ring manufacturing tool 100 according to an embodiment of the present invention, which is used for manufacturing a magnetic ring. As shown in fig. 1, the magnetic ring manufacturing tool 100 includes a base plate 10, a mandrel 20 fixed to the base plate 10, a replacing mechanism 30 connected to the mandrel 20, and a positioning mechanism 40 sleeved on the mandrel 20.
In this embodiment, the base plate 10 has a hexagonal structure. Each edge portion of the base plate 10 is provided with a first positioning hole 12, and the first positioning hole 12 is used for connecting with the displacement mechanism 30.
The spindle 20 is fixed to the bottom plate 10 at a central position.

The pressing plate 31 has a second positioning hole 312 at one end and a third positioning hole 314 at the other end, and has a through hole 316 at a position close to the angular position-limiting post 32 and the radial position-limiting post 33. The second positioning hole 312 corresponds to the first positioning hole 12 of the base plate 10, and the pressing plate 31 is connected to the base plate 10 through the second positioning hole 312. The third positioning hole 314 corresponds to the mandrel 20, and the pressing plate 31 is sleeved on the outer circumference of the mandrel 20 through the third positioning hole 314 and connected with the mandrel. The through hole 316 is used for the standard block or the magnetic block of the magnetic ring to pass through in the process of manufacturing the magnetic ring. It is understood that the displacement mechanism 30 can be changed from one station to the next by changing the position of the pressure plate 31 on the base plate 10 to effect rotation of the displacement mechanism 30 in the circumferential direction of the mandrel 20.
The angular position-limiting column 32 is disposed on one side of the through hole 316 of the pressing plate 31 in the circumferential direction, and is used for limiting the position of the standard block or the magnetic block of the magnetic ring in the circumferential direction during the process of manufacturing the magnetic ring.
The radial position-limiting column 33 is disposed on one side of the through hole 316 of the pressing plate 31 in the diameter direction, and is used for limiting the position of the standard block or the magnetic block of the magnetic ring in the diameter direction in the process of manufacturing the magnetic ring. It is understood that two radial spacers 33 may be provided, respectively on two sides of the through hole 316 of the pressure plate 31 in the diameter direction.
Two ends of the connecting plate 34 are respectively sleeved on the two radial limiting columns 33, and a through hole 342 is formed in the middle of the connecting plate 34 and used for allowing the pulling and pressing screw 35 to pass through in the process of manufacturing the magnetic ring.
The pulling screw 35 passes through the through hole 342 of the connecting plate 34 and the through hole 316 of the pressing plate 31 in the process of manufacturing the magnetic ring, so as to pull out the standard block of the magnetic ring or press in the magnetic block of the magnetic ring.
The positioning mechanism 40 includes an inner housing 42 and an outer housing 44 sleeved on the inner housing 42. The inner housing 42 is sleeved on the outer circumference of the mandrel 20. The inner wall 422 of the inner housing 42 is provided with through holes 424, and screws can be adopted to pass through the through holes 424 to fix the magnetic blocks in the process of manufacturing the magnetic ring. An accommodating space 46 is formed between the inner shell 42 and the outer shell 44, and the accommodating space 46 is used for placing a standard block and a magnetic block of a magnetic ring in the process of manufacturing the magnetic ring.
Referring to fig. 2 to fig. 6, the working process of manufacturing the magnetic ring by using the magnetic ring manufacturing tool 100 according to the embodiment of the present invention is as follows:
firstly, as shown in fig. 2, according to the technical index of the required magnetic ring, determining the specification of the magnetic ring, such as the inner diameter, the outer diameter, the thickness of the magnetic ring, the type of the magnetic steel and the like, through simulation calculation; secondly, equally dividing the magnetic ring into 12 fan-shaped magnetic blocks 101 along the circumferential direction, manufacturing standard blocks 102 made of aluminum materials or stainless steel materials with the same specification according to the size of the equally divided magnetic blocks 101, wherein the height of the standard blocks 102 can be slightly higher than that of the magnetic blocks 101, the top of each standard block 102 is provided with a screw hole, and the 12 magnetic blocks 101 are saturated and magnetized; then, the 6 magnetized magnetic blocks 101 and the 6 standard blocks 102 are taken out, and are arranged in the accommodating space 46 formed between the inner shell 42 and the outer shell 44 at intervals to form a complete circular ring, and the magnetic blocks 101 are fixed in the accommodating space 46 by screws penetrating through the through holes 424 of the inner shell 42. It is understood that the magnetic ring may be equally divided into 24 or 36 pieces in the circumferential direction. Taking 24 blocks as an example, the method can be used in a two-in-one mode, and the 24 blocks are combined into 12 two-in-one magnetic blocks for subsequent manufacturing; taking 36 blocks as an example, the subsequent manufacturing can be carried out after the 36 blocks are combined into 12 three-in-one magnetic blocks in a three-in-one mode. In a similar way, after the magnetic ring is equally divided into 12 blocks along the circumferential direction, each equally divided magnetic block can be further equally divided into 2 blocks or 3 blocks along the diameter direction, and then 12 two-in-one magnetic blocks are formed in a two-in-one or three-in-one mode and then subsequent manufacturing is carried out.
Step two, as shown in fig. 3 and 4, firstly, fixing the replacing mechanism 30 on the bottom plate 10, sequentially passing the pressure-pulling screw 35 through the through hole 342 of the connecting plate 34 and the through hole 316 of the pressure plate 31 to screw into the screw hole at the top of the standard block 102, and moving the pressure-pulling screw 35 upward to pull out the standard block 102; then, the magnetic block 101 is pressed into the receiving space 46 formed between the inner case 42 and the outer case 44 through the through hole 316 of the pressing plate 31 by using the pressing screw 35, thereby completing the replacement of one magnetic block 101.
And step three, as shown in fig. 5 and 6, the replacement mechanism 30 is fixed on the bottom plate 10 after rotating for 60 degrees around the circumference direction of the mandrel 20, then the work in the step two is repeated to complete the replacement of the next magnetic block 101, and the above operations are sequentially circulated to complete the replacement of the rest magnetic blocks 101.
It can be understood that if the required magnetic ring does not have the inner shell 42 and the outer shell 44, anaerobic adhesive needs to be applied to the two sides of the magnetic block 101 in the angular direction in the replacement process in the second step, so as to bond and fix the two adjacent magnetic blocks 101; if the required magnetic ring is provided with the inner shell 42 and the outer shell 44, anaerobic adhesive is not needed in the replacement process of the second step, so that adhesive-free bonding is realized.
The magnetic ring manufacturing tool 100 of the embodiment of the invention has the beneficial effects that:
1. the roundness and the flatness of the manufactured magnetic ring are ensured through the precise structure of the magnetic ring manufacturing tool 100;
2. anaerobic adhesive can be omitted in the replacement process, and adhesive-free bonding is realized;
3. the manufacturing efficiency is improved by adopting an interval replacement mode;
4. the specification size of the magnetic ring manufacturing tool 100 can be changed to manufacture magnetic rings with different dimensions.
