Description

Technical Field

[0001] This invention relates to motor assembly technology, and in particular to a stator support platform and an assembly machine for a rotor and a stator comprising the platform. Background Technology

[0002] High-speed permanent magnet motors have significant advantages such as high speed, relatively small motor size, high power density, and high efficiency. They do not require a speed change device when connected to high-speed loads or prime movers, thus overcoming many disadvantages of traditional motors such as high failure rate and difficult maintenance. Therefore, high-speed permanent magnet motors have broad application prospects in the industrial field.

[0003] Due to the large size and heavy weight of high-speed permanent magnet motors, manual assembly is quite difficult. Therefore, rotor and stator assembly machines for these motors have been developed. These machines typically include a stator support platform and a rotor fixing device. The rotor fixing device secures the rotor, while the stator support platform supports the stator. A drive mechanism moves the stator support platform and rotor fixing device relative to each other, allowing the rotor to be installed into the stator.

[0004] High-speed permanent magnet motors have rotors with extremely strong magnetic fields, and the air gap between the rotor and stator is small. Under such a strong magnetic field, if the coaxiality of the rotor and stator does not reach the required precision, assembling them becomes very difficult. Most existing rotor-stator assembly machines rely on a stator support platform and rotor fixing device for one-time positioning of the stator and rotor. However, during the actual assembly process, deviations in the machining dimensions of the rotor and stator may occur, and the precision of the equipment itself can also affect the accuracy of the rotor and stator positioning, impacting assembly quality. Furthermore, for applications where the same assembly machine is used to assemble rotors and stators of different motor models, the existing machines are not well-suited to the situation due to the differences in structural dimensions and weights of the motors. Summary of the Invention

Detailed Implementation

[0042] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0043] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0044] In the description of this invention, "several" means one or more, "more than" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0045] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0046] Reference Figures 1 to 3 A stator support platform includes: five bases 110, which are vertically stacked. The bottom base 110 is configured as a base, and the top base 110 is configured as a stator support. Adjacent bases 110 are interconnected, forming four connection methods: a connection that can swing back and forth and left and right, a connection that can rotate relative to a vertical axis, a connection that can move left and right, and a connection that can move up and down; and a horizontal adjustment mechanism 120, which is disposed between two bases 110 that can swing back and forth and left and right. The system includes a central adjustment mechanism 130, which adjusts the relative position of the two seats 110 to regulate their relative levelness; a rotation adjustment mechanism 130, which is located between the two seats 110 that can rotate relative to each other around a vertical axis, and is used to adjust the relative angular position between the two seats 110; a left-right adjustment mechanism 140, which is located between the two seats 110 that can move relatively left and right, and is used to adjust the relative position of the two seats 110 in the left-right direction; and a right-down adjustment mechanism 150, which is located between the two seats 110 that can move relatively up and down, and is used to adjust the relative position of the two seats 110 in the up-down direction. It should be understood that, in the description of this embodiment, the back-and-forth swinging of one seat 110 relative to another seat 110 refers to the swinging motion in which the front and rear ends of the relatively moving seats 110 alternately rise and fall; and the left-right swinging of one seat 110 relative to another seat 110 refers to the swinging motion in which the left and right ends of the relatively moving seats 110 alternately rise and fall.

[0047] The stator 1 is supported on the uppermost base 110, i.e., the stator support. The horizontal adjustment mechanism 120 can adjust the stator 1's horizontal level in the front-to-back and left-to-right directions; the rotation adjustment mechanism 130 can adjust the stator 1's angular position around the vertical axis; the left-to-right adjustment mechanism 140 can adjust the stator 1's left-to-right position; and the up-down adjustment mechanism 150 can adjust the stator 1's up-down position, thus achieving multi-directional position adjustment of the stator 1. During the assembly of the rotor 2 and stator 1, the position of the stator 1 can be quickly and conveniently adjusted according to the specific assembly situation to ensure that the coaxiality of the stator 1 and rotor 2 meets the assembly requirements, providing a foundation for high-precision assembly of the rotor 2 and stator 1.

[0048] In this embodiment, the five bases 110, from bottom to top, are a base, a horizontal adjustment base, a rotary adjustment base, a left-right adjustment base, and a stator support base. The horizontal adjustment base can swing back and forth and left and right relative to the base; the rotary adjustment base can rotate around a vertical axis relative to the horizontal adjustment base; the left-right adjustment base can move left and right relative to the rotary adjustment base; and the stator support base can move up and down relative to the left-right adjustment base. In some embodiments, the connection methods between the bases 110 can be interchanged to obtain another variation structure. For example, the connection relationships between the five bases 110 from bottom to top are: a connection that can rotate relative to each other around a vertical axis; a connection that can swing back and forth and left and right relative to each other; a connection that can move up and down relative to each other; and a connection that can move left and right relative to each other. This also achieves the effect of multi-directional position adjustment of the stator 1. Other structural variations and arrangements are also possible. Those skilled in the art can reasonably arrange the connection relationships between the five bases 110 according to specific needs.

[0049] In this embodiment, five seats 110 are provided. The connection relationships between the seats 110 include connections that can swing back and forth and left and right, connections that can rotate relative to each other around a vertical axis, connections that can move relative to each other left and right, and connections that can move relative to each other up and down. The relative positions between adjacent seats 110 are adjusted by a horizontal adjustment mechanism 120, a rotation adjustment mechanism 130, a left and right adjustment mechanism 140, and an up and down adjustment mechanism 150, respectively, so that the adjustment of the stator is more comprehensive.

[0050] In other embodiments, new seats 110 may be added to the existing five seats 110 as needed. The connection between the newly added seat 110 and the adjacent seat 110 may be selected from: a connection that can swing back and forth and left and right, a connection that can rotate relative to a vertical axis, a connection that can move left and right, and a connection that can move up and down, or other new connection relationships may be added (e.g., a connection that can move back and forth), thereby increasing the richness of the position adjustment of the stator 1.

[0051] In other embodiments, for cost considerations or by pre-positioning certain positions of the stator using positioning structures on the stator support, the number of support bodies 110 can be appropriately reduced, resulting in a stator support with a relatively simple structure and relatively low cost. For example, three support bodies 110 can be provided, and the connection between the three support bodies 110 can be two of the following: a connection that allows relative back-and-forth and left-and-right swinging, a connection that allows relative rotation around a vertical axis, a connection that allows relative left-and-right movement, and a connection that allows relative up-and-down movement. Then, an adjustment device is provided to adjust the relative position of adjacent support bodies 110. Of course, four support bodies 110 can also be provided, and two or three of the above four connection methods can be selected between the four support bodies 110, and the relative position of adjacent support bodies 110 can still be adjusted by providing an adjustment device. The stator support with at least three support bodies 110 and at least two connection methods described above can also achieve multi-directional adjustment of the stator, while having a relatively simple structure and low cost.

[0052] Reference Figure 3 In this embodiment, the two seats 110, which are capable of relative forward and backward and left and right swinging, are configured to swing relative forward and backward and left and right around a predetermined fulcrum. The horizontal adjustment mechanism 120 includes three lifters 121. The lifters 121 are disposed on the lower seat 110 and are used to lift the upper seat 110. Each lifter 121 has a lifting portion, which is arranged around the center line of gravity of the upper seat 110. It should be understood that the lifting portion refers to the part of the lifter 121 that lifts and supports the seat 110. By using the three lifters 121 around the center line of gravity of the upper seat 110, three-point adjustment can be formed, thereby adjusting the levelness in both forward and backward and left and right directions, while providing uniform support. In this embodiment, the lifting portion can be arranged around the predetermined fulcrum. Of course, it is conceivable that in some embodiments, the lifting portion can also be arranged on one side of the predetermined fulcrum.

[0053] In this embodiment, the lifting portions of two of the lifting devices 121 are arranged along the front-back direction to adjust the levelness in that direction, while the other lifting device 121 adjusts the levelness in the left-right direction. It is conceivable that in other embodiments, more than three lifting devices 121 may be provided, for example, four lifting devices 121, with two lifting devices 121 arranged along the front-back direction to adjust the levelness in that direction, and the other two lifting devices 121 arranged along the left-right direction to adjust the levelness in that direction.

[0054] In other embodiments, it is conceivable that the horizontal adjustment mechanism 120 may also be other structures, as long as the relative level of the two seats 110 can be adjusted, such as several motors that drive the two seats 110 to swing back and forth and left and right relative to each other.

[0055] Reference Figure 4 and Figure 5 The lifting device 121 includes a first lower lifting block 122, a first upper lifting block 123, and a lifting block driving mechanism. The first lower lifting block 122 is movably connected to the lower seat 110 and can move horizontally relative to the seat 110. The first lower lifting block 122 is provided with a first inclined surface 1221. The first upper lifting block 123 is fixedly disposed on the upper seat 110. The first upper lifting block 123 is provided with a second inclined surface 1231 adapted to the first inclined surface 1221. The first inclined surface 1221 and the second inclined surface 1231 abut against each other and can slide relative to each other. The lifting block driving mechanism is disposed on the lower seat 110 and is used to drive the first lower lifting block 122 to move back and forth. When the first lower lifting block 122 is driven back and forth by the lifting block driving mechanism, the first upper lifting block 123 can move up and down through the cooperation of the first inclined surface 1221 and the second inclined surface 1231, thereby lifting the upper seat 110. Here, the first upper lifting block 123 is the lifting part of the lifting device 121. In this embodiment, a slide is provided on the lower seat 110, and the first lower lifting block 122 is adapted to the slide and slidably disposed on the slide. Of course, the first lower lifting block 122 can also be connected to the seat 110 through other structures. In the art, there are many ways to realize the movable connection of one component relative to another component in a predetermined direction, and those skilled in the art can choose according to specific needs.

[0056] In this embodiment, the lifting block drive mechanism includes a second lead screw 1241, a second lead screw nut 1242, and a second lead screw drive mechanism 1243. The second lead screw 1241 is pivotally connected to the lower seat 110, and the second lead screw nut 1242 is fixedly disposed on the first lower lifting block 122. The second lead screw nut 1242 is screwed to the second lead screw 1241. The second lead screw drive mechanism 1243 is connected to the second lead screw 1241 and is used to drive the second lead screw 1241 to rotate. In this embodiment, the second lead screw drive mechanism 1243 is a handwheel, which drives the second lead screw 1241 to rotate. Of course, in some embodiments, the second lead screw drive mechanism 1243 can also be an electric drive device, such as a motor, to achieve electric adjustment. In other embodiments, the lifting block drive mechanism can also be other structures, such as a linear motor. In the art, there are many implementations of drive mechanisms that drive a component to move, which will not be described in detail here.

[0057] Reference Figures 6 to 9In this embodiment, the rotation adjustment mechanism 130 includes a pusher 131, an elastic resetter 132, and a mating block 133. The pusher 131 includes a push block 1311 and a push block driving mechanism 1312. The push block 1311 is movably connected to the lower seat 110 and can move horizontally relative to the seat 110. The push block driving mechanism 1312 is disposed on the lower seat 110 and is used to drive the push block 1311 to move back and forth. The elastic resetter 132 is disposed on the lower seat 110 and has a pressing part 1321, which can elastically extend and retract. The mating block 133 is fixedly disposed on the upper seat 110 and is clamped between the push block 1311 and the pressing part 1321. In this embodiment, the push block 1311 is connected to the lower seat 110 via a linear guide pair, thus enabling it to move horizontally. Of course, other structural methods can also be used to achieve the movable connection between the push block 1311 and the seat 110. In the art, there are many ways to achieve the movable connection of one component relative to another component in a predetermined direction, and those skilled in the art can choose according to specific needs.

[0058] The push block 1311 moves via the push block drive mechanism 1312, and rotates the upper seat 110 by pushing the mating block 133 on the upper seat 110, thereby adjusting the angle position. When adjusting the angle in the opposite direction, the push block 1311 moves in the opposite direction, and the mating block 133 is reset by the elastic resetter 132, thus allowing the angle position to be adjusted in the opposite direction. The aforementioned rotation adjustment mechanism 130 has a simple structure, is easy to implement, and is particularly suitable for fine-tuning the angle. The aforementioned elastic resetter 132 can be a readily available elastic buffer or implemented using a spring.

[0059] In this embodiment, the push block drive mechanism 1312 includes a motor, which drives the push block 1311 to move back and forth via a lead screw transmission. It is conceivable that the push block drive mechanism 1312 could also be other structures, such as a handwheel and a lead screw transmission mechanism, where the rotation of the handwheel is converted into the movement of the push block 1311 via the lead screw transmission mechanism. In the art, there are many other ways to drive a component to move, and these can be selected and designed as needed.

In the art, there are many ways to achieve a movable connection in which one component moves relative to another component in a predetermined direction, and those skilled in the art can choose according to specific needs.

[0064] It is conceivable that in other embodiments, the up-down adjustment mechanism 150 may be other structures, as long as it can adjust the relative up-down position, such as a linear drive that drives the two bodies 110 to move up-down relative to each other, such as a linear motor or a lifter.

[0067] Reference Figure 14 and Figure 15 In this embodiment, the base 110, which serves as the stator support, includes a main body 111 and a stator positioning and fixing mechanism. The stator positioning and fixing mechanism is disposed on the main body 111 and is used to position and fix the stator 1. The stator 1 can be fixed in a specific position by means of the stator positioning and fixing mechanism.

[0068] In this embodiment, the stator positioning and fixing mechanism includes a positioning seat 112 and a fixing mechanism 113. The positioning seat 112 is detachably connected to the body 111, and a positioning structure 1121 for positioning the stator 1 is provided on the positioning seat 112. The fixing mechanism 113 is disposed on the positioning seat 112 and is used to fix the stator 1 to the positioning seat 112. The positioning seat 112 is detachable, and different positioning seats 112 and fixing mechanisms 113 can be replaced according to the specific size of the stator 1, making it flexible and adaptable to stators 1 of different sizes. In this embodiment, the body 111 is provided with a plurality of positioning pins 1111, and the positioning seat 112 is provided with pin holes 1122 corresponding to the positioning pins 1111. The positioning seat 112 is installed to the body 111 through the mating of the positioning pins 1111 and the pin holes 1122.

[0069] In this embodiment, the positioning structure 1121 is a positioning pin, and a matching pin hole is pre-drilled on the stator 1. Of course, the positioning structure 1121 can also be other structures, such as a positioning groove, a positioning surface, a positioning hole, etc. In this art, there are many other ways to achieve the positioning of a component, and those skilled in the art can choose according to their needs.

[0070] In this embodiment, the fixing mechanism 113 includes a cylinder and a pressure rod. The pressure rod is connected to the cylinder rod of the cylinder, and the cylinder is disposed on the positioning seat 112. The cylinder drives the pressure rod to extend and retract. After the pressure rod extends, it abuts against the stator 1, pressing the stator 1 against the positioning seat 112. In this embodiment, four sets of cylinders and pressure rods are arranged to fix the four corners of the stator 1. Of course, the fixing mechanism 113 can also be other structures, such as a clamping mechanism. In the art, there are many ways to fix a component, and those skilled in the art can choose according to their needs.

[0071] Reference Figures 16 to 17 A rotor and stator assembly machine for loading rotor 2 into stator 1 includes: a machine base 200; a rotor fixing device 300 disposed on the machine base 200, wherein rotor 2 can be fixed to rotor fixing device 300 in a front-to-back manner; the aforementioned stator bearing platform 100 disposed on the machine base 200; and an loading drive device disposed on the machine base 200 for driving rotor fixing device 300 and stator bearing platform 100 to move relative to each other in the front-to-back direction so that rotor 2 can be loaded into stator 1.

[0072] Reference Figure 18When assembling the stator 1 and rotor 2, the stator 1 is fixed to the stator support platform 100, and the rotor 2 is fixed to the rotor fixing device 300. Based on the actual assembly situation, the coaxiality of the stator 1 and rotor 2 is adjusted via the stator support platform 100. By installing the drive device, the stator 1 and rotor 2 move relative to each other in the front-to-back direction, thus inserting the rotor 2 into the stator 1. The adjustment function of the stator support platform 100 improves the assembly accuracy. After inserting the rotor 2 into the stator 1, the front and rear end covers of the motor can be installed, thereby completing the assembly of the entire motor structure.

[0073] Reference Figures 16 to 17 In this embodiment, the rotor fixing device 300 includes a front seat 310, a rear seat 320, and a seat driving mechanism. The front seat 310 and the rear seat 320 are arranged one behind the other on the machine base 200. The stator bearing platform 100 is arranged between the front seat 310 and the rear seat 320. The front seat 310 and the rear seat 320 can move closer to each other or further away from each other. A front rotor fixing structure 311 is provided on the front seat 310, and a rear rotor fixing structure 321 is provided on the rear seat 320. When the front seat 310 and the rear seat 320 move closer to each other, the front rotor fixing structure 311 and the rear rotor fixing structure 321 can clamp and fix the rotor 2. The seat driving mechanism is arranged on the machine base 200 and is used to drive the front seat 310 and the rear seat 320 to move closer to each other or further away from each other.

[0074] In this embodiment, the rear rotor fixing structure 321 includes a chuck, and the front rotor fixing structure 311 includes a tail top. The tail top can rotate up and down around a predetermined fulcrum to adjust its position, thereby eliminating the different stress deformations caused by rotors of different weights on the rotor fixing device. Specifically, a fulcrum is set on the front seat 310, the tail top abuts against the fulcrum and can rotate around the fulcrum, and several pressing screws are set on the front seat 310. The pressing screws press the tail top at positions other than the fulcrum, and the screw depth is adjusted by rotating the pressing screws, allowing the tail top to rotate and adjust around the predetermined fulcrum. Of course, there are other structures in the art that can achieve the rotational adjustment of the tail top, and those skilled in the art can choose according to their needs. The chuck, as the rear rotor fixing structure 321, can serve as a reference positioning tool. It can directly clamp the end of the rotor or provide reference positioning by pressing the end of the rotor with a pin. In some embodiments, it is conceivable that the positions of the chuck and the tail top can be interchanged.

[0075] In this embodiment, the front rotor fixing structure 311 can be adjusted in position relative to the front seat 310 to accommodate rotors of different lengths. Similarly, the rear rotor fixing structure 321 can also be adjusted in position relative to the rear seat 320, or both the front and rear rotor fixing structures 311 and 321 can be adjusted in position relative to their respective front or rear seats 310 or 320, thus achieving the same function of accommodating rotors of different lengths. Specifically, in one embodiment, the front rotor fixing structure 311 can be movably connected to the front seat 310, specifically through a sliding connection, and its position can be positioned using a locking device (such as a locking screw, clamping mechanism, etc.). The implementation method for adjusting the rear rotor fixing structure 321's position is similar to the structure described above. Of course, it is conceivable that there are many ways to achieve the front-to-back position adjustment of the front rotor fixing structure 311 and / or the rear rotor fixing structure 321. In the art, there are many ways to enable one component to adjust its position relative to another component. Those skilled in the art can choose a suitable mechanism to achieve the above-mentioned functions as needed.

[0076] In this embodiment, the front seat 310 and the rear seat 320 are slidably connected to the machine base 200 via a linear guide pair. The guide rail of the linear guide pair is arranged in the front-to-back direction. The position of the rear seat 320 on the linear guide rail can be adjusted by a lead screw mechanism. The front seat 310 moves on the linear guide rail via a motor and a lead screw transmission mechanism, thereby moving closer to or away from the rear seat 320 to clamp the rotor 2. Of course, in other embodiments, other structural methods can also be used to achieve the mutual approach or distance between the front seat 310 and the rear seat 320. Those skilled in the art can choose according to their needs.

[0077] In this embodiment, the tail of the front rotor fixing structure 311 is a long pin, and the chuck of the rear rotor fixing structure 321 directly fixes the rotor end or presses the rotor with a short pin. The long pin can pass through the stator 1 supported on the stator support platform 100 and fix the rotor 2 on one side of the stator 1. When the rotor fixing device 300 and the stator support platform 100 move relative to each other, the long pin can exit the stator 1, so that the rotor 2 can be installed into the stator 1.

[0078] In this embodiment, the stator support platform 100 is movably connected to the machine base 200 and can move back and forth relative to the machine base 200. A drive device is installed to drive the stator support platform 100 to move back and forth. In this embodiment, the stator 1 is assembled onto the rotor 2 by the active movement of the stator support platform 100. Of course, the rotor 2 can also be moved to assemble with the stator 1. In this embodiment, the stator support platform 100 is movably connected to the machine base 200 through a linear guide pair. The drive device includes a motor and a lead screw transmission mechanism. The motor achieves linear drive of the stator support platform 100 through the lead screw transmission mechanism. Of course, in other embodiments, the drive device can also be other structures, such as a linear actuator, such as a linear motor, etc.

[0079] In this embodiment, a rotor lifting device 400 is also included. The rotor lifting device 400 is disposed on the machine base 200, between the front seat 310 and the rear seat 320. The rotor lifting device 400 includes a lifting platform 410 and a lifting drive mechanism 420 for driving the lifting platform 410 to rise and fall. When the lifting platform 410 is lowered, the stator bearing platform 100 can move to the upper side of the lifting platform 410. The rotor 2 can be placed on the lifting platform 410 for lifting and falling, thereby facilitating the installation of the rotor 2 between the front rotor fixing structure 311 and the rear rotor fixing structure 321. After the rotor 2 is clamped and fixed by the front rotor fixing structure 311 and the rear rotor fixing structure 321, the lifting platform 410 is lowered, and the stator bearing platform 100 moves to the upper side of the lifting platform 410, thereby completing the assembly of the rotor 2 into the stator 1. In this embodiment, the lifting drive mechanism 420 includes a motor and a lead screw transmission mechanism. The lead screw transmission mechanism converts the rotational power of the motor into the power for vertical movement, thereby driving the lifting platform 410 to rise and fall. In other embodiments, the lifting drive mechanism 420 can be other mechanisms. In the art, there are many other drive mechanisms that can drive the lifting platform 410 to rise and fall, which will not be described in detail here.

[0080] In this embodiment, a visual inspection device is also included. The visual inspection device includes a plurality of front cameras 510 and a plurality of rear cameras 520. The front and rear ends of the stator are pre-machined with inner or outer circular surfaces coaxial with the axis of the stator. The front cameras 510 are used to photograph the front end of the stator 1, and the rear cameras 520 are used to photograph the rear end of the stator 1. The visual inspection device can obtain the center position coordinates of the inner or outer circular surfaces of the front and rear ends of the stator by processing the image data obtained by the front cameras 510 and the rear cameras 520.

[0081] By setting up a visual inspection device and capturing images of the front and rear ends of stator 1 using a front camera 510 and a rear camera 520, the visual inspection device processes the visual data obtained from the front and rear cameras 510 and 520 to obtain the center coordinates of the inner or outer circular surfaces of the front and rear ends of stator 1. By comparing these two center coordinates with the axis coordinates of the rotor fixed by the rotor fixing device 300, the coaxiality deviation between stator 1 and rotor 2 can be obtained, thus providing a reference for adjusting the coaxiality of stator 1 and rotor 2. Specifically, when calculating the center coordinates, the axis of the rotor fixed by the rotor fixing device 300 can be used as a reference. In specific adjustments, manual adjustment can be performed using the stator support platform 100, or automated adjustment can be achieved by electrically connecting the visual inspection device to the electrically driven stator support platform 100.

[0082] Specifically, one method for obtaining the center coordinates of the inner or outer circular surfaces at both ends of the stator is as follows: a front camera 510 axially captures at least three positions of the inner or outer circular surface at one end of the stator, and a rear camera 520 axially captures at least three positions of the inner or outer circular surface at the other end of the stator. This can be achieved by using at least three front cameras 510 and at least three rear cameras 520, or by using one front camera 510 and one rear camera 520 sequentially moving to the aforementioned at least three positions. The visual inspection device processes the image data obtained by the front and rear cameras 510 to obtain the coordinates of at least three trajectory points of the circular trajectory of the inner or outer circular surfaces at both ends of the stator. Since three points can define a circle, the center coordinates of the inner or outer circular surfaces at both ends of the stator are calculated using the coordinates of these three trajectory points. Of course, in other embodiments, the center coordinates of the inner or outer circular surfaces at both ends of the stator can also be obtained in other ways, and are not limited to the implementation provided in this embodiment.

[0083] In this embodiment, the front camera 510 is connected to the stator support platform 100 via a camera bracket 530 and moves together with the stator support platform 100. The rear camera 520 is connected to the rear seat 320 via the camera bracket 530. Of course, the front camera 510 and the rear camera 520 can also be set in other ways, as long as they can capture the front and rear ends of the stator 1. In this embodiment, three front cameras 510 and three rear cameras 520 are each provided. Of course, in other embodiments, other reasonable numbers can be set as needed. The structure of the camera bracket 530 is as follows: Figure 19As shown, the frame structure has three cameras connected to the top beam, left vertical rod, and right vertical rod of the frame structure, respectively. To accommodate different stator sizes, the positions of the front camera 510 and rear camera 520 on the camera holder 530 are adjustable. Specifically, the front camera 510 and rear camera 520 are connected to a slide rail 540 and slidably connected to the camera holder 530 via the slide rail 540. The camera holder 530 is equipped with fastening screws 550, which can press against the slide rail 540 to lock it in place. To adjust the position, first loosen the fastening screws 550, adjust the camera to the appropriate position, and then tighten the fastening screws 550. In this embodiment, the fastening screws 550 have handles for easy adjustment.

[0084] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0085] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.

One of the front rotor fixing structure (311) and the rear rotor fixing structure (321) includes a chuck, and the other includes a tail top, the tail top being able to rotate up and down around a predetermined fulcrum to adjust its position; The front rotor fixing structure (311) and / or the rear rotor fixing structure (321) can be adjusted relative to the front seat (310) or the rear seat (320) where they are located; The stator support platform (100) is movably connected to the machine base (200) and can move back and forth relative to the machine base (200). The loading drive device is used to drive the stator support platform (100) to move back and forth. It also includes a rotor lifting device (400), which is disposed on the machine base (200) and between the front seat (310) and the rear seat (320). The rotor lifting device (400) includes a lifting platform (410) and a lifting drive mechanism (420) for driving the lifting platform (410) to rise and fall. When the lifting platform (410) is lowered, the stator bearing platform (100) can move to the upper side of the lifting platform (410).
