[0044] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0048] The present application proposes a block rotor bonding force testing device 100, which is combined with Figure 1 As shown, the block rotor bonding force testing device 100 includes a supporting mechanism 1000, a pulling mechanism 2000 and a measuring mechanism 3000. The block rotor 200 is mounted on and fixed to the supporting mechanism 1000. The pulling mechanism 2000 generates a force on the outer iron core 220 of the block rotor 200 to deviate from the inner iron core 230 of the block rotor 200, and the measuring mechanism 3000 is used to measure the displacement value of the outer iron core 220 under the pulling of the pulling mechanism 2000. The support mechanism 1000 is used to realize the installation and fixation of the block rotor 200, laying a foundation for evaluating the stability and reliability of the outer iron core 220. The pulling mechanism 2000 is used to apply a force to the outer iron core 220, and the direction of the force is away from the inner iron core, so that the outer iron core 220 can move away from the inner iron core. At the same time, the displacement value of the outer iron core 220 is measured by the measuring mechanism 3000, and the stability and reliability of the outer iron core 220 are evaluated through the cooperation of various components.

[0049] Specifically, combined Figure 6 and Figure 7As shown, the segmented rotor 200 includes a magnetic tile 240, an outer core 220, an inner core 230 and a rotating shaft 210. The inner core is sleeved on the rotating shaft 210 and fixed to the rotating shaft 210. There are multiple outer cores 220, and the multiple outer cores 220 are arranged around the inner core. The outer cores 220 and the inner core are at a certain distance from each other without direct contact. An installation cavity is formed between two adjacent outer cores 220. The magnetic tile is installed and fixed in the installation cavity. The magnetic tile, the outer core 220 and the inner core are combined together through a plastic coating process. The materials of the outer core 220 and the inner core include but are not limited to silicon steel sheets, aluminum alloys, etc., the materials of the magnetic tile include but are not limited to ferrite, aluminum nickel cobalt, neodymium iron boron, samarium cobalt, etc. The specific structural shape of the outer core 220, the specific structural shape of the inner core, and the structural coordination between the magnetic tile and the outer core 220 are not limited, and reference may be made to the relevant art.

[0050] The block rotor bonding force testing device 100 in this embodiment is used to test the bonding force of the block rotor 200 , so as to evaluate the stability and reliability of the outer iron core 220 .

[0051] The segmented rotor bonding force testing device 100 includes a supporting mechanism 1000, a pulling mechanism 2000 and a measuring mechanism 3000. The supporting mechanism 1000 is a main structural component of the segmented rotor bonding force testing device 100, and realizes stable support for the segmented rotor 200 and other components, avoids unstable installation due to the strong magnetism of the segmented rotor 200, and provides a basis for the operation of the segmented rotor bonding force testing device 100. The supporting mechanism 1000 can be made of metal materials, engineering plastics or other materials, and the segmented rotor 200 can be installed on the supporting mechanism 1000 and fixed. The structural form of the supporting mechanism 1000 is not limited, as long as the installation and fixation of the segmented rotor 200 can be achieved.

[0052] The pulling mechanism 2000 is used to apply a force to the outer core 220 away from the inner core, and the measuring mechanism 3000 is used to measure the displacement value of the outer core 220. The force applied by the pulling mechanism 2000 and the displacement value measured by the measuring mechanism 3000 can be used to evaluate the stability and reliability of the outer core 220. The pulling mechanism 2000 has various types, as long as it can generate a corresponding force on the outer core 220 and drive the outer core 220 to move. The same is true for the measuring mechanism 3000. The measuring mechanism 3000 has various types. The measuring mechanism 3000 can be based on the infrared ranging principle, the mechanical transmission principle, or a displacement sensor. For example, the measuring mechanism 3000 is a dial indicator. More examples are not listed here one by one.

[0053] For example, when evaluating the stability and reliability of the outer iron core 220, the segmented rotor 200 is installed and fixed to the supporting mechanism 1000, and one of the outer iron cores 220 is pulled by the pulling mechanism 2000. The pulling mechanism 2000 applies a preset force to the outer iron core 220, and the force is directed back to the inner iron core, so that the outer iron core 220 can be displaced. The measuring mechanism 3000 measures the displacement value of the outer iron core 220 away from the inner iron core. The stability and reliability of the outer iron core 220 can be evaluated by judging whether the displacement value is within a preset range. If the displacement value is within the preset range, the outer iron core 220 is not easy to detach under the centrifugal action, thereby ensuring the stability and reliability of the outer iron core 220. Since the magnetic tile is fixed between two adjacent outer iron cores 220, the stability and reliability of the magnetic tile is ensured. If the displacement value is outside the preset range, the outer iron core 220 is easy to detach under the centrifugal action, and the stability and reliability are insufficient.

[0054] Continue to combine Figure 1 As shown, in some embodiments of the present application, the segmented rotor 200 is installed and fixed to the support mechanism 1000 through its rotating shaft 210 , which can not only realize the installation of the segmented rotor 200 , but also facilitate the testing and evaluation of the outer core 220 .

[0055] Specifically, when testing the segmented rotor 200, the pulling mechanism 2000 needs to pull one of the outer cores 220, and the rest of the segmented rotor 200, except for the outer core 220, should remain stationary. Since the rotating shaft 210 is fixed to the inner core, it is more convenient to install and fix the entire segmented rotor 200 by fixing the rotating shaft 210, so that the structural complexity of the support mechanism 1000 can be simplified. In particular, the segmented rotor 200 is installed and fixed to the support mechanism 1000 through the rotating shaft 210, and the rest of the segmented rotor 200, except for the rotating shaft 210, can be suspended, and will not have excessive contact with the support mechanism 1000, so as to prevent the rest of the segmented rotor 200 from being damaged by collision with the support mechanism 1000.

[0056] Continue to combine Figure 1 As shown, in some embodiments of the present application, the support mechanism 1000 includes a base 1100, a first support plate 1200 and a second support plate 1300. The support mechanism 1000 is used to be placed on a support surface, which may be the ground or a work surface. When the support mechanism 1000 is placed on the support surface, the base 1100 contacts the support surface. The base 1100 is the support base of the support mechanism 1000. The specific structure of the base 1100 is not limited. Figure 1The base 1100 shown is a plate-like structure. The first support plate 1200 is arranged on the base 1100, so as to be fixed to the base 1100, and the second support plate 1300 is also arranged on the base 1100, so as to be fixed to the base 1100. There are many ways to fix the first support plate 1200 to the base 1100, and the second support plate 1300 to the base 1100, such as screw connection, latch connection or other connection methods, as long as the first support plate 1200 to the base 1100 and the second support plate 1300 to the base 1100 can be fixed. Based on this, the connection between the rotating shaft 210 and the supporting mechanism 1000 is fixed by fixing one end (the first end 211) of the rotating shaft 210 to the first supporting plate 1200, and the other end (the second end 212) of the rotating shaft 210 to the second supporting plate 1300. The portion between the two ends of the rotating shaft 210 of the segmented rotor 200 is located between the first supporting plate 1200 and the second supporting plate 1300, thereby achieving effective support for the segmented rotor 200.

[0057] In order to facilitate the installation of the rotating shaft 210 on the first supporting plate 1200 and the second supporting plate 1300, Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments of the present application, the first support plate 1200 is provided with a mounting groove 1610, and the mounting groove 1610 is provided with an opening 1620. When the segmented rotor 200 is installed, one end (the first end 211) of the rotating shaft 210 passes through the opening 1620 of the first support plate 1200 and slides into the mounting groove 1610 of the first support plate 1200 along the extension direction of the mounting groove 1610 of the first support plate 1200, and the installation and fixation of one end (the first end 211) of the rotating shaft is achieved through the mounting groove 1610 of the first support plate 1200. Similarly, the second support plate 1300 is also provided with a mounting groove 1610, and the mounting groove 1610 is provided with an opening 1620. When the segmented rotor 200 is installed, the other end (the second end 212) of the rotating shaft 210 passes through the opening 1620 of the second support plate 1300 and slides into the mounting groove 1610 of the second support plate 1300 along the extension direction of the mounting groove 1610 of the second support plate 1300. The other end (the second end 212) of the rotating shaft 210 is supported by the mounting groove 1610 of the second support plate 1300, which is convenient and quick. By providing the mounting groove 1610 on the first support plate 1200 and the second support plate 1300, and the mounting groove 1610 having the opening 1620, the segmented rotor 200 can be conveniently and quickly installed on the support mechanism 1000.

[0058] Combination Figure 1As shown, in some embodiments of the present application, the force direction of the pulling mechanism 2000 is perpendicular to the extension direction of the installation slot 1610, so that the rotating shaft 210 of the segmented rotor 200 can be prevented from slipping out of the installation slot 1610 when the pulling mechanism 2000 pulls the outer core 220 accordingly. It can be understood that the force direction of the pulling mechanism 2000 is the direction of the force generated on the outer core 220, such as Figure 1 As shown, the force direction of the pulling mechanism 2000 is from bottom to top, and the mounting groove 1610 extends in the front-to-back direction. When the pulling mechanism 2000 pulls the corresponding outer iron core 220 upward, the rotating shaft 210 is blocked by the groove wall of the mounting groove 1610, ensuring the stability of the remaining parts of the segmented rotor 200 except the pulled outer iron core 220.

[0059] Further, as mentioned above, one end (first end 211) of the rotating shaft 210 slides into the mounting groove 1610 on the first supporting plate 1200 through the opening 1620 on the first supporting plate 1200, and the other end (second end 212) of the rotating shaft 210 slides into the mounting groove 1610 on the second supporting plate 1300 through the opening 1620 on the second supporting plate 1300. In order to prevent one end (first end 211) of the rotating shaft 210 and the other end (second end 212) of the rotating shaft 210 from moving along the corresponding mounting groove 1610 and detaching from the mounting groove 1610 in an accidental situation, Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments of the present application, a stopper 1500 is provided, for example, the stopper 1500 is a pin, and a hole structure is provided on opposite sides of the mounting groove 1610 of the first support plate 1200, and the stopper 1500 is inserted into the hole structure. When one end (the first end 211) of the rotating shaft 210 slides out of the mounting groove 1610, the corresponding stopper 1500 can stop the one end (the first end 211) of the rotating shaft 210, thereby preventing the one end (the first end 211) of the rotating shaft 210 from sliding out of the mounting groove 1610 of the first support plate 1200. 10. Similarly, hole structures are also provided on opposite sides of the mounting groove 1610 of the second support plate 1300, and the stopper 1500 is inserted into the hole structure. When the other end (the second end 212) of the rotating shaft 210 slides out of the mounting groove 1610, the corresponding stopper 1500 can stop the other end (the second end 212) of the rotating shaft 210, thereby preventing the other end (the second end 212) of the rotating shaft 210 from sliding out of the mounting groove 1610 of the second support plate 1300, thereby improving the safety of the segmented rotor 200 being installed and fixed to the support mechanism 1000.

[0060] Combination Figure 1 and Figure 2As shown, in some embodiments of the present application, the base 1100 is provided with a waist-shaped hole 1110, and the waist-shaped hole 1110 is respectively arranged corresponding to the first support plate 1200 and the second support plate 1300, the first support plate 1200 is provided with a fastening hole 1210, and the second support plate 1300 is also provided with a fastening hole (not shown in the figure), and the support mechanism 1000 also includes a first fastener 1710, and the first support plate 1200 and the base 1100 are connected to each other through the first fastener 1710 passing through the waist-shaped hole 1110 and connected to the first support plate 1 The fastening holes 1210 of 200 realize the mutual fixation between the first support plate 1200 and the base 1100, and the second support plate 1300 and the base 1100 are fixed to each other by the first fastener 1710 passing through the waist-shaped hole 1110 and connected to the fastening hole of the second support plate 1300. Through the setting of the waist-shaped hole 1110, the relative distance between the first support plate 1200 and the second support plate 1300 can be adjusted to adapt to the segmented rotor 200 with different thicknesses.

[0061] Specifically, if Figure 1 and Figure 2 As shown, the first support plate 1200 is arranged on the upper side of the base 1100, and the corresponding first fastener 1710 passes through the waist-shaped hole 1110 from bottom to top and is connected to the fastening hole 1210 of the first support plate 1200, so that the first support plate 1200 and the base 1100 are fixed to each other. Similarly, the second support plate 1300 is arranged on the upper side of the base 1100, and the corresponding first fastener 1710 passes through the waist-shaped hole 1110 from bottom to top and is connected to the fastening hole of the second support plate 1300, so that the second support plate 1300 and the base 1100 are fixed to each other. The first fastener 1710 can be a screw, and the fastening hole is a screw hole. The first support plate 1200 and the second support plate 1300 are oriented to each other in a first direction, as shown in FIG. Figure 1 In the left and right directions, the waist-shaped hole 1110 needs to extend along the left and right directions, so that the distance between the first support plate 1200 and the second support plate 1300 can be adjusted to adapt to the segmented rotors 200 with different thicknesses.

[0062] Combination Figure 1 and Figure 3As shown, in some embodiments of the present application, the support mechanism 1000 also includes a connecting plate 1400, the base 1100 is connected to one end of the first support plate 1200 and one end of the second support plate 1300, and the connecting plate 1400 is connected to the other end of the first support plate 1200 and the other end of the second support plate 1300, for example, the base 1100 is connected to the bottom end of the first support plate 1200 and the bottom end of the second support plate 1300, and the connecting plate 1400 is connected to the top end of the first support plate 1200 and the top end of the second support plate 1300, so as to enhance the structural stability of the support mechanism 1000, and there are multiple ways to connect the connecting plate 1400 to the first support plate 1200 and the second support plate 1300. Figure 1 The fastening is shown via a screw connection.

[0063] Combination Figure 1 As shown, in some embodiments of the present application, the measuring mechanism 3000 is fixed on the supporting mechanism 1000. Since the segmented rotor 200 is mounted and fixed on the supporting mechanism 1000, in this embodiment, the measuring mechanism 3000 is also fixed to the supporting mechanism 1000. The segmented rotor 200 and the measuring mechanism 3000 have a unified installation reference, which is beneficial to improving the accuracy of the measurement. In addition, by fixing the measuring mechanism 3000 to the supporting mechanism 1000, it is avoided that the measuring mechanism 3000 is externally placed, which causes the segmented rotor bonding force testing device 200 to occupy too much space.

[0064] In order to facilitate the connection between the measuring mechanism 3000 and the supporting mechanism 1000, the combination 1 and Figure 3 As shown, in some embodiments of the present application, the support mechanism 3000 also includes a connecting plate 1400, and the connecting plate 1400 is provided with a socket 1410 and a locking hole 1420, and the socket 1410 and the locking hole 1420 are intersected and connected, and the so-called intersecting and connecting means that the axial direction of the socket 1410 and the axial direction of the locking hole 1420 intersect and the socket 1410 and the locking hole 1420 are connected, and the measuring mechanism 3000 passes through the socket 1410, and a part of the measuring mechanism 3000 is penetrated in the socket 1410, and a second fastener 1430 is provided, for example, the second fastener 1430 is a screw, and the second fastener 1430 can be tightened in the locking hole 1420 and press against the part of the measuring mechanism 3000 in the socket 1410, so as to achieve the fixation of the measuring mechanism 3000.

[0065] Combination Figure 1 As shown, in some embodiments of the present application, the measuring mechanism 3000 has a contact end 3100 , which is disposed in the force application direction of the pulling mechanism 2000 , and the contact end 3100 abuts against the outer iron core 220 .

[0066] Specifically, in this embodiment, the measuring mechanism 3000 is a contact type measuring mechanism 3000, see Figure 1 In the orientation shown, the force direction of the pulling mechanism 2000 acts on the corresponding outer core 220 from bottom to top. When the pulling mechanism 2000 applies force, the corresponding outer core 220 moves upward, and the contact end 3100 is arranged above the outer core 220 and abuts against the outer core 220. The displacement of the outer core 220 drives the contact end 3100, causing the contact end 3100 to produce a small displacement, and then the displacement of the contact end 3100 is processed by the measuring mechanism 3000 (the working principle of the measuring mechanism 3000 itself), so as to obtain the displacement value, which is convenient and quick. It can be understood that the abutment can be direct abutment or indirect abutment.

[0067] Furthermore, combined with Figure 1 As shown, the measuring mechanism 3000 also includes a display module 3200. The display module 3200 can be mechanical or digital. The displacement of the contact end 3100 is processed by the measuring mechanism 3000, and the displacement value is finally displayed through the display module 3200, which is intuitive and convenient.

[0068] For example, the measuring mechanism 3000 is a dial indicator, and the end of the dial indicator constitutes the contact end 3100. When the outer iron core 220 is displaced, the contact end 3100 is driven to displace slightly. After internal processing of the dial indicator, the displacement value is finally displayed through its display module 3200. There are many specific structures of the dial indicator, which are not limited here one by one.

[0069] Combination Figure 1 As shown, in some embodiments of the present application, the pulling mechanism 2000 includes a pulling arm 2100 and a latch 2200 , and the pulling mechanism 2000 is connected to the outer core 220 via the pulling arm 2100 and the latch 2200 , thereby generating force on the outer core 220 .

[0070] Specifically, the pull arm 2100 is provided with a hole structure, and the outer iron core 220 is also provided with a hole structure. The latch 2200 needs to pass through the hole structure of the pull arm 2100 and the hole structure of the outer iron core 220. Figure 1 As shown, the latch 2200 passes through the pulling arm 2100 and the outer core 220 in sequence along the left-right direction (the axial direction of the segmented rotating shaft 210). When the pulling mechanism 2000 is pulled by the pulling arm 2100, the pulling arm 2100 drives the latch 2200, and the latch 2200 transmits the force to the outer core 220, thereby generating a force on the outer core 220 that deviates from the inner core. Through such an arrangement, the connection between the pulling mechanism 2000 and the outer core 220 is conveniently achieved.

[0071] The pulling mechanism 2000 pulls the outer iron core 220 via the pulling arm 2100. In order to enable the pulling mechanism 2000 to apply accurate pulling force, the pulling mechanism 2000 also includes a pulling machine (not shown in the figure). The pulling machine and the pulling arm 2100 are drivingly connected, and the pulling arm 2100 is pulled via the pulling machine.

[0072] Furthermore, combined with Figure 1 As shown, in some embodiments of the present application, in order to further improve the pulling reliability between the pulling arm 2100 and the outer core 220, the pulling arm 2100 includes a first arm 2110 and a second arm 2120, the first arm 2110 is arranged on one side of the outer core 220, and the second arm 2120 is arranged on the other side of the outer core 220, and the latch 2200 needs to pass through the first arm 2110, the outer core 220 and the second arm 2120, for example Figure 1 As shown, the first arm 2110, the second arm 2120 and the rest of the pulling arm 2100 form a structure similar to a bicycle front fork. When the outer iron core 220 is pulled, the opposite sides of the outer iron core 220 are pulled, the force distribution is more uniform, and the pulling process is smoother, thereby avoiding accidental separation of the pulling arm 2100 and the outer iron core 220 during the pulling process.

[0073] In some embodiments of the present application, the measuring mechanism 3000 is disposed between the first arm 2110 and the second arm 2120. Figure 1 As shown, the measuring mechanism 3000 is arranged between the first arm 2110 and the second arm 2120 and is located above the segmented rotor 200, so as to maximize the use of space, the overall structure of the segmented rotor bonding force testing device 100 is more compact, and the contact end 3100 of the measuring mechanism 3000 is conveniently located in the force application direction of the pulling mechanism 2000.

All equivalent structural changes made based on the concept of the present application and the contents of the present application description and drawings, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
