[0035] Please refer again Fig.11 In some embodiments, the second blocking portion 422a and the second mounting portion 422b are arranged along the axial direction of the indexing plate 41, and the second blocking portion 422a further includes a second limiting surface 422d, and the second limiting surface 422d is located at one end of the second blocking portion 422a facing the second mounting portion 422b; specifically, in some embodiments, the width of the second blocking portion 422a is greater than the width of the second mounting portion 422b, and when the second blocking piece 422 is installed, it is moved along Fig.19 Move in the F direction as shown (the F direction is parallel to the axial direction of the dividing plate 41 ) to insert the second mounting portion 422b into the second slide groove 411b until the second limiting surface 422d abuts against the end surface of the dividing plate 41 , thereby completing the installation of the second baffle 422 .

[0036] Please refer again Figure 7 In some embodiments, the indexing plate 41 includes a first chuck 411 and a second chuck 412, and the first chuck 411 and the second chuck 412 are arranged along the axial direction of the indexing plate 41; the second slide groove 411b is located on the side of the first slide groove 411a facing the axis of the indexing plate 41, the first slide groove 411a penetrates the first chuck 411 along the axial direction of the indexing plate 41, and the second slide groove 411b penetrates the first chuck 411 and the second chuck 412 along the axial direction of the indexing plate 41; when installing the first baffle 421 and the second baffle 422, place them along the Figure 5 or Fig.19 The first stopper 421 is inserted into the first slot 411a of the first chuck 411, and the second stopper 422 is inserted into the second chuck 412. The first slot 411c penetrates the first chuck 411 along the axial direction of the indexing disk 41, and the second slot 411d penetrates the first chuck 411 and the second chuck 412 along the axial direction of the indexing disk 41.

[0037] Please refer again Figure 7 In some embodiments, the width of the first slide groove 411a perpendicular to the radial direction of the indexing plate 41 is defined as the first width, and the first width of the first slide groove 411a remains unchanged along the radial direction of the indexing plate 41; the width of the second slide groove 411b perpendicular to the radial direction of the indexing plate 41 is defined as the second width, and the second width of the second slide groove 411b remains unchanged along the radial direction of the indexing plate 41; the first width is greater than the second width. Figure 7, define the size of the first width as M, the size of the second width as N, when the first width is not equal to the second width, the first slide groove 411a and the second slide groove 411b can respectively install the first mounting portion 421b and the second mounting portion 422b of different thicknesses. At this time, the thickness of the first blocking portion 421a and the first mounting portion 421b can be the same, and the thickness of the second blocking portion 422a and the second mounting portion 422b can also be the same. It is only necessary to ensure that the thickness of the first blocking portion 421a and the second blocking portion 422a are different. That is, the first slide groove 411a and the second slide groove 411b are used to install the first blocking piece 421 and the second blocking piece 422 respectively. In some embodiments, the width of the first slide groove 411a is greater than the width of the second slide groove 411b, that is, the width of the groove body on the radial outer side is greater than the width of the groove body on the inner side, which is more convenient for processing the mounting groove 4110. Of course, in some other embodiments, M may be less than N, so that the width of the first slide groove 411a is smaller than the width of the second slide groove 411b; or M may be equal to N. In this case, the thickness of the first mounting portion 421b and the second mounting portion 422b are the same, but the thickness of the first blocking portion 421a and the second blocking portion 422a are different.

[0038] See also Fig.10 and Fig.11 In some embodiments, the first blocking portion 421a has the same thickness as the first mounting portion 421b; the overall thickness of the first blocking piece 421 is kept consistent, which is convenient for processing. Of course, in some other embodiments, the first mounting portion 421b and the first blocking portion 421a may also adopt a structure with inconsistent thickness. Among them, the first blocking portion 421a and the first mounting portion 421b are an integral part or an assembled connection. The second mounting portion 422b has the same thickness as the second blocking portion 422a. The overall thickness of the second blocking piece 422 is kept consistent, which is convenient for processing. Of course, the second blocking portion 422a and the second mounting portion 422b may also adopt a structure with inconsistent thickness. Among them, the second blocking portion 422a and the second mounting portion 422b are an integral part or an assembled connection.

[0039] See also Figures 1 to 5 In some embodiments, the first central cavity 40 axially penetrates the indexing plate 41, and the axis of the first central cavity 40 coincides with the axis of the indexing plate 41; the magnetic steel indexing assembly 4 has a magnetic steel limit groove 400, which is arranged at intervals along the circumference of the indexing plate 41, and the magnetic steel limit groove 400 is located between two adjacent baffles 42. The tooling of this embodiment can be applied to Fig. 20The motor rotor 10 shown is pasted with magnetic steel, and the motor rotor 10 includes a rotor core 101 and a magnetic steel 102. Of course, it can also be used for other rotors that need to paste magnetic steel. In some embodiments, when pasting a circle of magnetic steel 102 circumferentially, the magnetic steel 102 is placed in each magnetic steel limiting groove 400, and the magnetic steel 102 can be pasted with the rotor core 101. Among them, the baffle plate 42 can limit the circumferential position of the magnetic steel 102, and the baffle plate 42 is used to limit the gap between two adjacent magnetic steels 102 in the same circle. The outer surface of the rotor core 101 and / or the inner ring side of the magnetic steel 102 has a glue coating, and the surface of the dividing plate 41 and the baffle plate 42 has an anti-stick coating, such as a Teflon coating.

[0040] In some embodiments, the thickness of the first baffle 421 is greater than the thickness of the second baffle 422. When using the tooling, the rotor core 101 is passed through the first central cavity 40 of the magnetic steel indexing assembly 4. When pasting a circle of magnetic steel 102, the magnetic steel 102 is placed in the magnetic steel limiting groove 400, and the magnetic steel 102 is pasted to the rotor core 101. The baffle 42 can limit the circumferential position of the magnetic steel 102, and the baffle 42 is used to limit the gap between two circumferentially adjacent magnetic steels 102. By selecting the first baffle 421 and the second baffle 422 of appropriate thickness to adapt to the gap between two circumferentially adjacent magnetic steels 102, the adaptability of the tooling is improved.

[0041] Specifically, in some embodiments, when the consistency of the magnetic steels 102 to be pasted is good, the required gap between the two magnetic steels 102 can be determined according to the specific width size of the magnetic steels 102, and the first baffle 421 or the second baffle 422 can be selected to limit the magnetic steels 102. For example, when the width size of all the magnetic steels 102 pasted in the same circle in the circumferential direction is relatively small, the first baffle 421 with a larger thickness can be used in one circle of the magnetic steel indexing assembly 4 to limit the two magnetic steels 102; when the width size of all the magnetic steels 102 pasted in the same circle in the circumferential direction is relatively large, or is standard, the second baffle 422 with a smaller thickness can be used in one circle of the magnetic steel indexing assembly 4 to limit the two magnetic steels 102.

[0042] In some other embodiments, when the consistency of the magnetic steel 102 is not good, the width of the magnetic steel 102 circumferentially pasted in the same circle is first measured, and then it is determined whether to select the first baffle 421 or the second baffle 422 to limit the position between the two circumferentially adjacent magnetic steels 102. At this time, a circle of the magnetic steel indexing assembly 4 can partially use the first baffle 421 with a larger thickness and partially use the second baffle 422 with a smaller thickness. For example, when the width of two circumferentially adjacent magnetic steels 102 is relatively small, the first baffle 421 with a larger thickness is used to limit the position between the two magnetic steels 102. When there is a magnetic steel 102 with a larger width or a standard width in two circumferentially adjacent magnetic steels 102, the second baffle 422 with a smaller thickness can be used to limit the position between the two magnetic steels 102.

[0043] Of course, when the consistency of the magnets 102 is poor, and there are both oversized and standard-sized magnets 102 in all the magnets 102 circumferentially pasted in the same circle, and the number of multiple circumferentially adjacent magnets 102 of smaller sizes is not greater than 2, a circle of the magnet dividing assembly 4 can also use a second baffle 422 with a smaller thickness to limit the position between two magnets 102.

[0044] Please refer again Figures 1 to 4 In some embodiments, the tooling further comprises a base 1, a fixture assembly 2, a first connecting member 3, a magnetic steel indexing assembly 4 and an adjusting limit assembly 5, one end of the first connecting member 3 is connected to the base 1, the other end of the first connecting member 3 is connected to the fixture assembly 2, the base 1, the magnetic steel indexing assembly 4 and the fixture assembly 2 are arranged along the axial direction of the magnetic steel indexing assembly 4, and the magnetic steel indexing assembly 4 is located between the base 1 and the fixture assembly 2; in some embodiments, one end of the adjusting limit assembly 5 is connected to one of the base 1 and the magnetic steel indexing assembly 4, the other end of the adjusting limit assembly 5 is connected to the other of the base 1 and the magnetic steel indexing assembly 4, and the distance between the magnetic steel indexing assembly 4 and the base 1 can be adjusted. By adjusting the connection position of the adjusting limit assembly 5 and the base 1, or adjusting the connection position of the adjusting limit assembly 5 and the magnetic steel indexing assembly 4, the position adjustment of the magnetic steel indexing assembly 4 in the axial direction is achieved, and by changing the axial position of the magnetic steel indexing assembly 4, it can be suitable for the pasting of multiple turns of magnetic steel.

[0045] The tooling of this embodiment can be applied to Fig. 20 The magnetic steel pasting of the motor rotor 10 shown can of course also be used for other rotors that need to be pasted with magnetic steel. Figure 3 and Figure 4In some embodiments, when the tooling is used, one end of the rotor core 101 is inserted into the base 1, and the rotor core 101 passes through the first central cavity 40 of the indexing plate 41, and then the other end of the rotor core 101 is inserted into the clamp assembly 2; the base 1 and the clamp assembly 2 are connected by the first connecting member 3, and the rotor core 101 is axially limited by the base 1 and the clamp assembly 2. At this time, the indexing plate 41 is located between the base 1 and the clamp assembly 2. Among them, the baffle 42 can limit the gap between two adjacent magnetic steels 102, and the baffle 42 can be selected according to the size of the magnetic steel 102. Before pasting, the width dimensions of a batch of magnetic steels 102 to be pasted are measured (for example, measured by a go-no-go gauge), and the required gap between the two magnetic steels 102 can be determined according to the specific width dimensions of the magnetic steel 102, and the first baffle 421 or the second baffle 422 can be selected to limit the magnetic steel 102. When the width of two circumferentially adjacent magnetic steels 102 is too small, a thicker barrier sheet 42 is used for positioning. When at least one of the two circumferentially adjacent magnetic steels 102 is too large or has a standard width, a thinner barrier sheet 42 is used for positioning the two magnetic steels 102.

[0046] In some embodiments, when the magnetic steels 102 pasted on the same circle have good consistency, according to their specific width dimensions, a circle of the indexing plate 41 can all use the first baffles 421 of the same specification thickness or the second baffles 422 of the same specification thickness to limit the circumferential position of the magnetic steels, such as Figure 5 As shown, each baffle 42 can be inserted into the indexing plate 41 along the F direction. When the magnetic steels 102 are pasted, it is preferred to paste the magnetic steels 102 with good consistency in the same circle.

[0047] In some other embodiments, when the consistency of the magnetic steel 102 pasted in the same circle is not good, the first baffle 421 and the second baffle 422 of different thicknesses can be combined and installed with the indexing plate 41 to limit the circumferential position of the magnetic steel 102, such as Fig.19 As shown, each baffle 42 can be inserted into the indexing plate 41 along the F direction. Of course, when the consistency of the magnetic steel 102 pasted in the same circle is not good, if there is no small width in the magnetic steel 102 pasted in the same circle, the whole circle of the indexing plate 41 can also use baffles 42 with smaller thickness. The selected baffles 42 are inserted and matched with the indexing plate 41, and then the first circle of magnetic steel 102 can be pasted.

[0048] When pasting the first circle of magnetic steel 102, first place the first piece of magnetic steel 102 of the first circle in the magnetic steel limiting groove 400 between the baffles 42, then move the dividing plate 41 to the left until the two ends of the first piece of magnetic steel 102 of the first circle are respectively against the clamp assembly 2 and the dividing plate 41, and then adjust the limiting assembly 5 to connect with the magnetic steel dividing assembly 4 and the base 1, and fix the axial position of the magnetic steel dividing assembly 4 by adjusting the limiting assembly 5, and then the other magnetic steels 102 of the first circle can be pasted. Among them, the outer surface of the rotor core 101 and / or the inner ring side of the magnetic steel 102 have a glue coating, and when the magnetic steel 102 is pasted to the rotor core 101, the baffles 42 can limit the circumferential position of the magnetic steel 102, and the surfaces of the dividing plate 41 and the baffles 42 have an anti-stick coating, such as a Teflon coating. Among them, the first piece of magnetic steel 102 is preferably a magnetic steel 102 with a larger length dimension. The polarities of two adjacent magnets 102 in the same circle are opposite.

[0049] See also Figure 3 and Figure 4 In some embodiments, the tooling further includes a holding ring 6, through which a circle of magnetic steel 102 after pasting can be positioned. When pasting the next circle of magnetic steel 102, it is necessary to position the previous circle of magnetic steel 102 after pasting through the holding ring 6 before moving the magnetic steel dividing assembly 4, so that the previous circle of magnetic steel 102 pasted and the rotor core 101 remain in a pasted and attached state, thereby reducing the change in the position of the magnetic steel 102 caused by the collision between the magnetic steel dividing assembly 4 and the magnetic steel 102 during the movement.

[0050] When pasting the second circle of magnetic steel 102, move the dividing plate 41 to the right to a suitable position, and remove the baffle plate 42 from the first circle of magnetic steel 102 pasted. Then, according to the measured width of the magnetic steel 102 to be pasted, install the required baffle plate 42 to the dividing plate 41 again, place the first magnetic steel 102 of the second circle in the magnetic steel limiting groove 400 between the baffle plates 42, and then move the dividing plate 41 to the left until the two ends of the first magnetic steel 102 of the second circle are respectively against the first circle of magnetic steel 102 and the dividing plate 41, and then fix the axial position of the magnetic steel dividing assembly 4 again by adjusting the limiting assembly 5, and then the second circle of magnetic steel 102 can be pasted with staggered poles. After the pasting of the second circle of magnetic steel 102 is completed, the holding ring 6 can be used to position the pasted upper circle of magnetic steel 102. Among them, the polarity of the two axially adjacent magnetic steels 102 is the same.

[0051] Repeating the above actions can realize the pasting of multiple turns of magnetic steel 102 in the axial direction of the rotor core 101.

Taking the case where the base 1 has the first positioning hole 7a and the adjustment limit assembly 5 cooperates with the arc hole as an example, two sets of nut members can be used to connect the adjustment limit assembly 5 with the base 1, wherein the two sets of nut members are respectively located on the side of the base 1 facing away from the magnetic steel indexing assembly 4 and the side of the base 1 facing the magnetic steel indexing assembly 4.

In some embodiments, when a circle of magnets 102 are pasted circumferentially, the magnets 102 are placed in each magnet limiting groove 400, and the magnets 102 can be pasted to the rotor core 101. Among them, the baffle 42 can limit the circumferential position of the magnet 102, and the baffle 42 is used to limit the gap between two adjacent magnets 102 in the same circle.

[0066] When pasting the first circle of magnets 102, first place the first piece of magnet 102 of the first circle in the magnet limiting groove 400 between the baffles 42, and then move the dividing plate 41 to the left until the two ends of the first piece of magnet 102 of the first circle respectively abut against the clamp assembly 2 and the dividing plate 41 (in this embodiment, the clamp assembly 2 can be used to limit the magnet 102, and of course, other methods can also be used to limit the magnet 102), and then connect the adjustment limit assembly 5 to the magnet dividing assembly 4 and the base 1, and fix the axial position of the magnet dividing assembly 4 by adjusting the limit assembly 5, and then the other magnets 102 of the first circle can be pasted.
