That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features. Throughout the specification, the same reference numerals indicate the same elements.

[0047] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clearly, the technical solutions of the present invention are further explained below with reference to the accompanying drawings and through specific implementation methods.

[0048] In this embodiment, a profiling back iron slide tool is proposed, which can be transferred between the installation stations of the magnetic steel platen, the magnetic steel, and the soft magnetic composite sheet, so that the magnetic steel platen, the magnetic steel, and the soft magnetic composite sheet can be assembled on the profiling back iron through the movement and flipping of a profiling back iron slide tool, and the magnetic steel platen, the magnetic steel, and the soft magnetic composite sheet on the profiling back iron can be flipped and assembled on the back iron. Among them, the magnetic steel platen / magnetic steel and the soft magnetic composite sheet are installed on the profiling back iron from bottom to top, that is, a magnetic steel is arranged between two adjacent magnetic steel platens, and the soft magnetic composite sheet is horizontally placed on the magnetic steel platen and the magnetic steel.

[0049] It is worth mentioning that the contoured back iron and the back iron are both supporting parts that can provide installation support for the magnetic steel, magnetic steel pressure plate and soft magnetic composite sheet respectively. The contoured back iron only serves as a transit medium in the assembly process. The structure of the contoured back iron is similar to that of the back iron.

[0050] Specifically, Figures 1 to 5 As shown, the profiling back iron slide tooling 71 includes a slide 711 and a flip assembly 713; wherein the slide 711 is slidably arranged along the Y axis between the installation stations of the magnetic steel, the magnetic steel pressure plate and the soft magnetic composite sheet, and a flip table 715 for positioning and placing the profiling back iron 702 is movably connected to the slide 711, and the profiling back iron 702 can rotate around the Z axis relative to the flip table 715, and the flip table 715 can flip around the X axis relative to the slide 711, so as to drive the profiling back iron 702 to flip to the top parallel to the back iron; the fixed end of the flip assembly 713 is arranged on the slide 711, and the driving end of the flip assembly 713 is connected to the flip table 715 to drive the flip table 715 to flip around the X axis, so as to drive the profiling back iron 702 and the magnetic steel, the magnetic steel pressure plate and the soft magnetic composite sheet thereon to rotate around the X axis as a whole, so that the profiling back iron 702 can rotate 180° to the top parallel to the back iron.

[0051] Compared with the prior art, the contoured back-iron slide tool 71 in this embodiment has changed the specific structure of the contoured back-iron slide tool 71; the slide 711 is slidably arranged along the Y-axis to realize the reciprocating movement of the slide 711 along the Y-axis between various installation stations; and the flip table 715 for positioning and placing the contoured back-iron 702 is movably connected to the slide 711, so that the flip assembly 713 drives the flip table 715 to rotate around the X-axis relative to the slide 711, so as to realize the reciprocating flipping of the flip table 715 relative to the slide 711 on the X-axis, so as to drive the contoured back-iron 702 and the structure placed thereon to flip to a position parallel to the back-iron. At the same time, the profiling back iron 702 is rotated around the Z axis relative to the flip table 715, so as to switch the assembly posture of the profiling back iron 702 when assembling the magnetic steel pressure plate, the magnetic steel and the soft magnetic composite sheet; by integrating the movement and rotation functions in various directions in the profiling back iron slide tooling 71, the profiling back iron 702 positioned and placed on the profiling back iron slide tooling 71 can correspond to each installation mechanism, so that the profiling back iron slide tooling 71 can be uniformly converted and used between various installation stations, without the need to set up a large number of profiling back iron slide tooling 71, saving costs, and the transfer operation is simple and convenient.

[0052] It is worth noting that by making the slide 711 slide along the Y axis, the slide 711 can slide to each installation station, so that the magnetic steel, the magnetic steel pressure plate and the soft magnetic composite sheet can be positioned and placed in the profiling back iron 702 at each installation station; and by making the profiling back iron 702 rotate around the Z axis relative to the flip table 715, the profiling back iron 702 can be rotated step by step by an angle, which is conducive to the annular installation of multiple magnetic steels and multiple magnetic steel pressure plates in the profiling back iron 702. Among them, the magnetic steel and the magnetic steel pressure plate placed horizontally are specifically formed by multiple soft magnetic composite sheets spliced ​​together to form a soft magnetic composite sheet ring.

[0053] Specifically, if Figure 1 and Figure 2 As shown, a plurality of support rods 712 are arranged between the slide 711 and the flip table 715, that is, one end of the support rod 712 is fixedly connected to the slide 711, and there is no direct connection between the other end of the support rod 712 and the flip table 715, that is, the flip table 715 is freely overlapped on the other end of the support rod 712, so that the flip table 715 can be flipped around the X-axis relative to the slide 711.

[0054] Specifically, if Figure 1 and Figure 2As shown, the profiling back iron slide tooling also includes a rotating toothed disc 716, a rotating driving member and a rotating gear 717; wherein, a rotating toothed disc 716 is coaxially sleeved outside the profiling back iron 702, and a rotating driving member and a rotating gear 717 are respectively arranged on the flip table 715, and the rotating driving member is drivingly connected with the rotating gear 717 to drive the rotating gear 717 to rotate around the Z axis, and the rotating gear 717 is meshingly connected with the rotating toothed disc 716, so that the profiling back iron 702 can be driven to rotate synchronously through the rotation of the rotating toothed disc 716, thereby realizing that the profiling back iron 702 is rotated around the Z axis and arranged on the flip table 715. wherein, the rotating driving member can be specifically a motor.

[0055] Furthermore, if Figure 2 As shown, the contoured back-iron slide tooling 71 also includes a positioning piece 718 and a second positioning pin 719; wherein, a plurality of positioning pieces 718 are connected in a ring shape on the outer periphery of the contoured back-iron 702; the second positioning pin 719 is arranged on the flip table 715, and the second positioning pin 719 can move along the Z axis and be inserted into a positioning piece 718 aligned therewith to limit the rotation of the contoured back-iron 702.

[0056] Specifically, in the installation steps such as installing the magnetic steel pressure plate or pushing the magnetic steel, since the profiling back iron 702 needs to be stepped and rotated around the Z axis relative to the flip table 715, the number of positioning pieces 718 needs to match the number of magnetic steels and the number of magnetic steel pressure plates. After the profiling back iron 702 completes each stepping rotation, the profiling back iron 702 will drive a positioning piece 718 to align with the second positioning pin 719; correspondingly, the second positioning pin 719 can be understood as a linear cylinder fixed on the flip table 715. The positioning pin installed at the top of the piston rod is driven by the linear cylinder to move up and down, so that the second positioning pin 719 can be inserted into a positioning piece 718 aligned with it, so that the rotation of the contoured back iron 702 can be limited by the mutual limiting effect of the positioning piece 718 and the second positioning pin 719, so that the contoured back iron 702 can be rigidly limited in the process of pushing the magnetic steel, so as to avoid the rotation of the contoured back iron 702, thereby ensuring that the position of the contoured back iron 702 on the turning table 715 remains unchanged.

[0057] Furthermore, if Figure 2As shown, the contoured back-iron slide tooling 71 also includes a support column 710, one end of which is fixedly connected to the flip table 715. When the flip table 715 flips around the X-axis to be located above the back-iron, the other end of the support column 710 is supported on a back-iron carrier for positioning the back-iron. On the one hand, it can avoid collision between the flip table 715 and the back-iron and the back-iron carrier during the process of flipping the flip table 715 around the X-axis to be located above the back-iron. On the other hand, it can be supported between the flip table 715 and the back-iron carrier by the support column 710 to ensure the positioning accuracy of the contoured back-iron 702 relative to the back-iron after flipping, which is conducive to accurately transferring the magnetic steel pressure plate / magnetic steel and the soft magnetic composite sheet in the contoured back-iron 702 to be assembled into the back-iron.

[0058] Specifically, Figure 1 and Figure 2 As shown, the flip assembly 713 includes a first driving member 7131 and a transmission member; wherein the fixed end of the first driving member 7131 is disposed on the slide 711, and the output shaft of the first driving member 7131 is connected to the transmission member to drive the transmission member to move, so that the transmission member drives the flip table 715 to rotate around the X-axis relative to the slide 711. In this embodiment, the first driving member 7131 can be a motor.

[0059] Furthermore, if Figure 1 As shown, the transmission member includes a rotating shaft 7132, and a first gear 7133 and a second gear 7134 that are meshed with each other, the rotating shaft 7132 extends along the X-axis, the first gear 7133 is sleeved on the output shaft of the first driving member 7131, the second gear 7134 is sleeved on the rotating shaft 7132, and the flip table 715 is fixedly connected to the rotating shaft 7132.

[0060] Specifically, if Figure 1 As shown, when the first driving member 7131 is working, the first driving member 7131 drives the first gear 7133 to rotate, thereby driving the second gear 7134 and the rotating shaft 7132 to rotate, so that the rotating shaft 7132 drives the flip table 715 to rotate around the X-axis, thereby realizing the flipping of the flip table 715 around the X-axis.

[0061] Furthermore, if Figure 2 and Figure 3 As shown, the flipping assembly 713 also includes a plurality of anti-falling parts 7135, and a plurality of anti-falling parts 7135 are circumferentially arranged on the inner ring of the contoured back iron 702, that is, the magnetic steel, the magnetic steel pressure plate and the soft magnetic composite sheet are all located between the inner ring and the outer edge of the contoured back iron 702, so that the anti-falling parts 7135 are used to support the magnetic steel, the magnetic steel pressure plate and the soft magnetic composite sheet on the contoured back iron 702 when the flipping platform 715 is flipped.

[0062] Furthermore, in this embodiment, if Figures 3 to 5As shown, the anti-falling part 7135 can specifically be a bolt, that is, the head of the bolt is used to support the magnet, the magnetic steel pressure plate and the soft magnetic composite sheet on the profiling back iron 702, the rod of the bolt is used to be threadedly connected to the profiling back iron 702, and the head of the bolt is higher than the magnetic steel pressure plate placement surface 7021 on the profiling back iron 702 for placing the magnetic steel pressure plate, and the magnetic steel pressure plate placement surface 7021 is higher than the magnetic steel placement surface 7022 on the profiling back iron 702 for placing the magnet.

[0063] By setting a circle of anti-falling parts 7135, it can support the magnetic steel pressure plate, magnetic steel and soft magnetic composite sheet installed on the contoured back iron 702 when flipping the contoured back iron 702, prevent the magnetic steel pressure plate, magnetic steel and soft magnetic composite sheet from shifting in position due to their own weight during the flipping process, and ensure that the placement positions of the magnetic steel pressure plate, magnetic steel and soft magnetic composite sheet in the contoured back iron 702 remain unchanged during the flipping process, so that the magnetic steel pressure plate, magnetic steel and soft magnetic composite sheet can be accurately flipped and assembled into the back iron.

[0064] It is worth mentioning that in order to enable the contoured back iron 702 to generate magnetic attraction with the magnet, the magnet placement surface 7022 in the contoured back iron 702 is made of a magnetic conductive material (such as iron), so that the magnetic attraction between the magnet and the contoured back iron 702 can prevent the magnet from shifting during the flipping process, thereby ensuring that the positions of the magnet pressure plate and the soft magnetic composite sheet will not shift, and better ensuring that the placement positions of the magnet pressure plate, magnet and soft magnetic composite sheet in the contoured back iron 702 remain unchanged during the flipping process, thereby more accurately flipping the magnet pressure plate, magnet and soft magnetic composite sheet into the back iron.

[0065] In addition, the magnetic steel pressure plate placement surface 7021 in the contoured back iron 702 is made of magnetic isolation material (such as stainless steel). Compared with making the contoured back iron 702 completely made of magnetic conductive material, it is possible to ensure the magnetic attraction effect between the contoured back iron 702 and the magnetic steel while preventing the magnetic attraction force from being generated between the contoured back iron 702 and the magnetic steel pressure plate. Thus, the overall magnetic attraction force of the contoured back iron 702 is relatively low, so that the contoured back iron 702 and the magnetic steel, the magnetic steel pressure plate and the soft magnetic composite sheet can be separated more easily, so that the magnetic steel, the magnetic steel pressure plate and the soft magnetic composite sheet can be transferred and assembled onto the back iron more easily as a whole.

[0066] Furthermore, if Figure 1As shown, the contoured back iron slide tooling 71 also includes a positioning component 714, which is arranged on the slide 711. The positioning component 714 is used to position the magnetic steel pressure plate onto the contoured back iron 702 to ensure that the magnetic steel pressure plate can be accurately placed on the contoured back iron 702 to avoid positional deviation of the magnetic steel pressure plate on the contoured back iron 702, thereby ensuring the accuracy of the placement of the magnet placed between two adjacent magnetic steel pressure plates on the contoured back iron 702.

[0067] Specifically, Figures 1 to 3 As shown, the positioning assembly 714 includes a second driving member 7141, a base plate 7142 and a first positioning pin 7143; wherein the fixed end of the second driving member 7141 is arranged on the slide 711; the base plate 7142 is spaced above the slide 711, the driving end of the second driving member 7141 is connected to the base plate 7142 to drive the base plate 7142 to move along the Z axis, and the first positioning pin 7143 is connected to the base plate 7142, and the first positioning pin 7143 can be inserted into the positioning hole of the magnetic steel pressure plate upward along the Z axis to position the magnetic steel pressure plate on the contoured back iron 702. In this embodiment, the second driving member 7141 can be specifically a linear cylinder.

[0068] Furthermore, if Figures 1 to 3 As shown, a plurality of first positioning pins 7143 are provided on the base plate 7142 along its circumference, and a first positioning pin 7143 can be inserted into a positioning hole of a magnetic steel pressure plate upward along the Z axis to position each magnetic steel pressure plate on the contoured back iron 702 respectively.

[0069] like Figure 3 As shown, by setting a plurality of first positioning pins 7143, and making a first positioning pin 7143 inserted into a positioning hole of a magnetic steel pressure plate upward along the Z axis, the plurality of magnetic steel pressure plates can be arranged in a ring shape on the contoured back iron 702 through the positioning effect of each first positioning pin 7143; and the second driving member 7141 can drive the base plate 7142 to move downward along the Z axis, so that each first positioning pin 7143 is disengaged from the positioning hole of the magnetic steel pressure plate at the same time, so that the first positioning pin 7143 will not interfere with the flipping of the contoured back iron 702.

[0070] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
