[0015] For ease of description, we define three mutually perpendicular coordinate axes in space as the X-axis, the Y-axis, and the Z-axis. The direction along the X-axis is the longitudinal direction, the direction along the Y-axis is the transverse direction, and the direction along the Z-axis is the vertical direction. The X-axis and Y-axis are two mutually perpendicular coordinate axes in the same horizontal plane, and the Z-axis is the vertical coordinate axis. The X-axis, Y-axis, and Z-axis are located in three mutually perpendicular planes in space: the XY plane, the YZ plane, and the XZ plane. The XY plane is a horizontal plane, the XZ plane and the YZ plane are both vertical planes, and the XZ plane is perpendicular to the YZ plane. The three axes in space are the X-axis, Y-axis, and Z-axis. Movement along these three axes in space refers to movement along the three mutually perpendicular axes in space, specifically movement along the X-axis, Y-axis, and Z-axis in space. Planar movement, on the other hand, refers to movement in the XY plane.

[0016] See also Figure 1 and Figure 2 The magnetic ring press machine provided in this embodiment includes a frame 100, a shaft feeding mechanism 510, a press-fitting device 200, a magnetic ring feeding mechanism 700 and a press-fitting conveying mechanism 300. The frame 100 has a first direction X, a second direction Y and a vertical direction Z that are perpendicular to each other. The shaft feeding mechanism 510 is used to supply the motor shaft 10. Figure 11The press-fitting device 200 includes a press-fitting bracket 210, a pressing drive 220, a lifting drive 230, a clamping drive 240, and a press-fitting head 250. The lifting drive 230 and the pressing drive 220 are mounted on the press-fitting bracket 210 with a vertical spacing, and the press-fitting head 250 is mounted on the output end of the pressing drive 220. The pressing head 250 and the output ends of the lifting drive 230 are coaxially arranged vertically to clamp the motor shaft 10 vertically and ensure the stability of the motor shaft 10 in the XY plane. The clamping drive 240 is mounted on the press-fitting head 250 and is used to horizontally clamp the motor shaft 10.

[0017] Combine Figure 3 The magnetic ring loading mechanism 700 includes a first bracket 710, a loading turntable 720, and a sleeve loading mechanism 730, a gluing mechanism 740, a magnetic ring supply mechanism 750 and a magnetic ring output mechanism 760 arranged in sequence around the loading turntable 720. The loading turntable 720 is rotatably installed on the first bracket 710 around the vertical direction Z. The sleeve loading mechanism 730 is used to supply the core sleeve 31 to the loading turntable 720, the gluing mechanism 740 is used to glue the outer periphery of the core sleeve 31, the magnetic ring supply mechanism 750 is used to supply the magnetic ring part 32 to the loading turntable 720, so that the magnetic ring part 32 is sleeved on the glued core sleeve 31 to form a magnetic ring assembly 30, and the magnetic ring output mechanism 760 is used to pick up the magnetic ring assembly 30 on the loading turntable 720. The press-fitting conveying mechanism 300 is used to convey the motor shaft 10 from the shaft loading mechanism 510 to the press-fitting device 200 , and is used to convey the magnetic ring assembly 30 from the magnetic ring output mechanism 760 to the press-fitting device 200 .

[0018] Based on this, the sleeve feeding mechanism 730 supplies the core sleeve 31 to the upper feeding turntable 720, and the feeding turntable 720 rotates, so that the core sleeve 31 passes through the gluing mechanism 740, the magnetic ring supply mechanism 750 and the magnetic ring output mechanism 760 in sequence, that is, the core sleeve 31 is glued in sequence, glued with the magnetic ring part 32 to form the magnetic ring assembly 30, and the magnetic ring assembly 30 is removed from the feeding turntable 720. The press-fitting conveying mechanism 300 respectively conveys the motor shaft 10 from the shaft feeding mechanism 510 and the magnetic ring assembly 30 from the magnetic ring output mechanism 760 to the press-fitting device 200, and the press-fitting device 200 presses the motor shaft 10 into the magnetic ring assembly 30 (see Figure 10 ). The magnetic ring press machine integrates the automatic gluing of the magnetic ring assembly 30 and the integrated process of sleeve shaft pressing, avoiding the material transfer and waiting time when the assembly of the magnetic ring assembly 30 and the shaft insertion are operated on different equipment in the traditional method, shortening the overall production cycle and improving production efficiency. In addition, the magnetic ring assembly 30 is assembled by gluing to reduce mechanical damage to the magnetic ring part 32 and the core sleeve 31, and avoids deformation of the components that affects the subsequent shaft insertion; during the shaft insertion press, the pressing head 250 and the jacking drive part 230 are arranged coaxially up and down to ensure the coaxiality of the magnetic ring assembly 30 with the motor shaft 10 during press installation.

[0019] In some embodiments, combined Figure 4 and Figure 5 The loading turntable 720 is equipped with at least two positioning components 721, and all positioning components 721 are spaced apart along the periphery of the loading turntable 720. When one positioning component 721 is operating in a certain process (such as gluing), other positioning components 721 can be operated synchronously in adjacent processes (such as sleeve loading, magnetic ring assembly, and component output), which greatly shortens the idle time of the equipment and improves production efficiency. Specifically, the positioning component 721 is used to position and place the core sleeve 31, ensuring that the position and posture of the core sleeve 31 on the loading turntable 720 are fixed, avoiding problems such as uneven gluing and skewness of the magnetic ring 32 when assembled due to the offset of the core sleeve 31, and improving the consistency of product quality.

[0020] Optionally, the number of positioning components 721 is four, and the four positioning components 721 are evenly distributed on the edge of the loading turntable 720 around the vertical axis, that is, the central angle between two adjacent positioning components 721 is 90°, and the four positioning components 721 are respectively docked with the magnetic ring supply mechanism 750, the gluing mechanism 740, the sleeve loading mechanism 730 and the magnetic ring output mechanism 760, so that the magnetic ring supply mechanism 750, the gluing mechanism 740, the sleeve loading mechanism 730 and the magnetic ring output mechanism 760 can operate continuously, thereby improving production efficiency.

[0021] In one embodiment, combined Figure 5 and Figure 6 The positioning assembly 721 has a positioning groove 722, which is used to limit the core sleeve 31 and realize the horizontal positioning of the core sleeve 31 on the positioning assembly 721. A first positioning column 723 is provided at the bottom of the positioning groove 722. The first positioning column 723 is used to receive the core sleeve 31 and ensure that the center hole of the core sleeve 31 is not deformed, which facilitates the subsequent smooth press assembly with the motor shaft 10.

[0022] In one embodiment, combined Figures 4 to 6 The positioning assembly 721 has a positioning notch 724, and the loading turntable 720 is equipped with a positioning driver 726. The output end of the positioning driver 726 is connected to a second positioning post 725 for driving the second positioning post 725 into and out of the positioning notch 724. When the positioning assembly 721 rotates to dock with any one of the magnetic ring supply mechanism 750, the gluing mechanism 740, the sleeve feeding mechanism 730, and the magnetic ring output mechanism 760, the positioning driver 726 drives the second positioning post 725 into the positioning notch 724, so that the positioning assembly 721 cannot rotate or shake relative to the magnetic ring supply mechanism 750, the gluing mechanism 740, the sleeve feeding mechanism 730, and the magnetic ring output mechanism 760 can operate stably.

[0023] In one embodiment, combined Figure 4 and Figure 5The positioning notch 724 is located above the loading turntable 720, and the positioning drive 726 is installed below the loading turntable 720. This fully utilizes the idle space below the loading turntable 720 and avoids spatial conflicts with operating components above, such as the sleeve loading mechanism 730 and the gluing mechanism 740. The loading turntable 720 has a bar-shaped movable through-hole 728, which serves as a guide for the movement of the second positioning post 725. The bottom end of the second positioning post 725 is connected to the positioning drive 726. The top end of the second positioning post 725 passes through the movable through-hole 728 and is exposed on the loading turntable 720. Driven by the positioning drive 726, the second positioning post 725 moves in and out of the positioning notch 724 along the length of the movable through-hole 728.

[0024] In some embodiments, combined Figure 4 and Figure 6 The loading turntable 720 has a mounting hole 729. The positioning assembly 721 includes a fixed sleeve 7211, a rotating rod 7212, and a rotating plate 7213. The fixed sleeve 7211 is fixedly mounted in the mounting hole 729. The rotating rod 7212 is rotatably mounted in the fixed sleeve 7211. The rotating rod 7212 is disposed throughout the loading turntable 720. The rotating plate 7213 is mounted on top of the rotating rod 7212. The rotating plate 7213 is used to support the core sleeve 31, so that the core sleeve 31 can be angularly positioned as the rotating plate 7213 rotates. Optionally, a positioning bearing 7214 is disposed between the fixed sleeve 7211 and the rotating rod 7212.

[0025] In one embodiment, combined Figure 3 and Figure 7 The bottom end of the rotating rod 7212 is provided with a rotating slot 727 which passes through the rotating rod 7212 in a radial direction. The magnetic ring loading mechanism 700 also includes a radial driving member 773 installed on the first bracket 710. The radial driving member 773 and the gluing mechanism 740 are arranged adjacent to each other. The output end of the radial driving member 773 is connected to the rotating driving member 772. The output shaft of the rotating driving member 772 is connected to the rotating connecting block 774. The rotating driving member 772 is used to drive the rotating connecting block 774 to rotate around the vertical direction Z. The radial driving member 773 drives the rotating driving member 772 to perform a linear motion so that the rotating connecting block 774 enters and exits the rotating slot 727 of the same positioning component 721 corresponding to the gluing mechanism 740. When the positioning assembly 721 rotates to the side of the gluing mechanism 740, the radial driving member 773 drives the rotating driving member 772 to move radially so that the rotating connecting block 774 is embedded in the rotating slot 727. The rotating driving member 772 drives the rotating connecting block 774 and the corresponding positioning assembly 721 to rotate. At the same time, the gluing mechanism 740 applies glue to the side wall of the core sleeve 31 on the positioning assembly 721. As the core sleeve 31 rotates, 360° gluing is achieved on the side wall of the core sleeve 31.

[0026] Specifically, combined Figure 3 、 Figure 4 and Figure 7 The magnetic ring loading mechanism 700 also includes a positioning push plate 775, which is installed at the output end of the radial driving member 773. The positioning push plate 775 moves along the same straight line as the output end of the positioning driving member 726 under the drive of the radial driving member 773. Therefore, when the radial driving member 773 drives the rotating driving member 772 and the positioning push plate 775 to move toward the positioning assembly 721, the positioning push plate 775 will abut the output end of the positioning driving member 726, ensuring that the output end of the positioning driving member 726 leaves the positioning notch 724, and then the rotating connecting block 774 connected to the rotating driving member 772 is embedded in the rotating slot 727, which can drive the rotating rod 7212 to rotate freely without being hindered by the second positioning column 725.

[0027] In some embodiments, combined Figure 3 The magnetic ring feeding mechanism 700 also includes a gluing visual detector 771, which is installed on the first bracket 710. The gluing visual detector 771 and the gluing mechanism 740 are arranged adjacent to each other. The gluing visual detector 771 performs gluing quality inspection on the same core sleeve 31 corresponding to the gluing mechanism 740, thereby visually inspecting the appearance quality and gluing quality of the core sleeve 31.

[0028] In some embodiments, combined Figure 3 The magnetic ring feeding mechanism 700 also includes a magnetic ring recovery mechanism 780 installed on the first bracket 710. The magnetic ring recovery mechanism 780 is located at one end of the magnetic ring output mechanism 760 close to the loading turntable 720. The magnetic ring recovery mechanism 780 is used to recover the core sleeve 31 that fails the glue coating quality inspection to avoid the unqualified core sleeve 31 being pressed onto the motor shaft 10.

[0029] Specifically, the magnetic ring press also includes a controller, which is electrically connected to the glue coating visual detector 771, the magnetic ring supply mechanism 750 and the magnetic ring recovery mechanism 780 respectively. When the glue coating visual detector 771 visually detects that the core sleeve 31 is unqualified, the magnetic ring supply mechanism 750 is controlled not to feed the magnetic ring part 32 to the core sleeve 31, and the magnetic ring recovery mechanism 780 is controlled to recover the core sleeve 31.

[0030] In some embodiments, combined Figure 3The magnetic ring recovery mechanism 780 includes a recovery box 781, a recovery guide tube 782, and a recovery drive 783. The recovery box 781 and the recovery drive 783 are mounted on the first bracket 710. The recovery drive 783 drives the recovery guide tube 782 to move in a direction perpendicular to the conveying direction of the magnetic ring output mechanism 760 to receive the core sleeve 31 and guide it to the recovery box 781. When the core sleeve 31 is unqualified, the recovery drive 783 drives the recovery guide tube 782 to move and dock with the unqualified core sleeve 31 on the magnetic ring output mechanism 760. The core sleeve 31 falls into the recovery box 781 through the recovery guide tube 782.

[0031] Optionally, the conveying direction of the magnetic ring output mechanism 760 is the second direction Y, and the moving direction of the recovery guide tube 782 is the first direction X.

[0032] In some embodiments, combined Figure 3 and Figure 8 The sleeve loading mechanism 730 includes a first storage rack 731, a first pushing drive member 732, a first pushing plate 733, a first loading conveyor belt 734 and a first biaxial movable clamp 735. The first storage rack 731 includes a first bottom plate 736 and a plurality of first storage rods 737 arranged side by side. Optionally, the plurality of first storage rods 737 are spaced apart along the second direction Y. Each first storage rod 737 is used for stacking the core sleeves 31. A first gap 738 is defined between the bottom of the first storage rod 737 and the first bottom plate 736. The first gap 738 is greater than the height of a single core sleeve 31 and less than the stacked height of two core sleeves 31. The first gap 738 accurately controls the ejection of one layer of core sleeves 31 at a time. The first pushing drive 732 drives the first pushing plate 733 in and out of the first gap 738 to push the core sleeve 31 toward the first loading conveyor belt 734. The two ends of the first loading conveyor belt 734 are respectively connected to the first storage rack 731 and the first biaxial movable clamp 735. The first biaxial movable clamp 735 places the core sleeve 31 located on the first loading conveyor belt 734 onto the loading turntable 720.

[0033] Based on this, multiple side-by-side first storage rods 737 can form a circumferential limit for the stacked core sleeves 31, and the storage quantity is large, reducing the number of refills. The first push drive 732 pushes the first push plate 733 into the first gap 738, pushing the core sleeves 31 that have fallen from the multiple first storage rods 737 toward the first loading conveyor belt 734. Each first storage rod 737 pushes out a corresponding core sleeve 31, achieving the synchronous push-out of multiple side-by-side core sleeves 31. At the end of the first loading conveyor belt 734, the core sleeves 31 are transported to the loading turntable 720 by the first biaxial movable clamp 735.

[0034] Optionally, the first biaxial movable fixture 735 can move along the vertical direction Z and the first direction X, and the first loading conveyor belt 734 is located on one side of the loading turntable 720 in the first direction X.

[0035] In some embodiments, the magnetic ring supply mechanism 750 includes a second storage rack 751, a second push drive member, a second push plate, a second loading conveyor belt 754 and a second biaxial mobile fixture 755, and the second storage rack 751 includes a second base plate and a plurality of second storage rods arranged side by side. Optionally, a plurality of second storage rods are spaced apart along the second direction Y. Each second storage rod is used to stack the magnetic ring parts 32, and there is a second gap between the bottom of the second storage rod and the second base plate. The second gap is greater than the height of a single magnetic ring part 32 and less than the stacking height of two magnetic ring parts 32. The second gap accurately controls the release of a layer of magnetic ring parts 32 at a time. The second pushing drive drives the second pushing plate in and out of the second gap to push the magnetic ring part 32 toward the second loading conveyor belt 754. The two ends of the second loading conveyor belt 754 are respectively connected to the second storage rack 751 and the second biaxial movable clamp 755. The second biaxial movable clamp 755 places the magnetic ring part 32 located on the second loading conveyor belt 754 on the loading turntable 720.

[0036] Optionally, the second biaxial movable fixture 755 can move along the vertical direction Z and the first direction X, and the second loading conveyor belt 754 is located on one side of the loading turntable 720 in the first direction X.

[0037] In some embodiments, combined Figure 9 、 Figure 11 and Figure 12 The press-fit bracket 210 includes a press-fit bottom plate 211 and a press-fit top plate 212. The press-fit bottom plate 211 is mounted on the frame 100. The press-fit top plate 212 is located above the press-fit bottom plate 211 and is connected to the press-fit bottom plate 211 through a press-fit column 213. The press-fit bottom plate 211 has a first hollow portion 214 for the output shaft of the jacking drive 230 to pass through (see Figure 12 ), the lifting driving component 230 is installed on the press-fitting top plate 212, and the pressing driving component 220 is installed on the press-fitting top plate 212.

[0038] In some embodiments, combined Figure 14 and Figure 15 The press-fitting conveying mechanism 300 includes a conveying drive 310, a conveying guide 320 and a carrying block 330. The conveying guide 320 is installed on the frame 100 and extends along the first direction X and crosses the press-fitting base plate 211. The conveying guide 320 has a second hollow portion 321, and the second hollow portion 321 is used for the output end of the jacking drive 230 to pass through. The carrying block 330 is installed on the conveying guide 320. The carrying block 330 has a third hollow portion 331. The conveying drive 310 directly or indirectly drives the carrying block 330 to move along the first direction X so that the projection of the third hollow portion 331 in the vertical direction Z overlaps with the output end of the jacking drive 230.

[0039] In some embodiments, refer back to Figure 1 and Figure 9 The press-fitting conveying mechanism 300 includes a first conveying mechanism 410 and a second conveying mechanism 420 , which are respectively located at two ends of the conveying guide 320 in the first direction X. The first conveying mechanism 410 is used to convey the magnetic ring assembly 30 to the carrying block 330 , and the second conveying mechanism 420 is used to convey the motor shaft 10 to the carrying block 330 .

[0040] Specifically, first, driven by the transmission driver 310, the carrier block 330 moves along the first direction X to the second transport mechanism 420. The second transport mechanism 420 transports the motor shaft 10 to the carrier block 330, and the carrier block 330 moves the motor shaft 10 along the first direction X to below the press-fitting head 250. Second, the press-fitting head 250 and the output end of the lifting driver 230 clamp the motor shaft 10 vertically. The clamping driver 240 is used to horizontally clamp the motor shaft 10. The output end of the lifting driver 230 descends, thereby clamping and securing the motor shaft 10 on the press-fitting device 200. Third, the carrier block 330 moves the magnetic ring assembly 30 directly below the press-fitting head 250. The output end of the lifting driver 230 and the press-fitting head 250 clamp the motor shaft 10 vertically and descend synchronously, pressing the motor shaft 10 into the magnetic ring assembly 30, thereby completing the assembly of the motor shaft 10 and the magnetic ring assembly 30.

[0041] In some embodiments, the magnetic ring loading mechanism 700 is located on one side of the press-fitting conveying mechanism 300 in the second direction Y, and the magnetic ring output mechanism 760 is used to transport the magnetic ring assembly 30 along the second direction Y.

[0042] In one embodiment, the magnetic ring press further includes a core loading mechanism 600 for supplying the core pieces 20 . The core loading mechanism 600 and the magnetic ring loading mechanism 700 are located at the same end of the press conveyor mechanism 300 in the first direction X and on both sides of the press conveyor mechanism 300 in the second direction Y. The first transport mechanism 410 is used to transport the core pieces 20 to the carrying block 330 . Specifically, the carrying block 330 is driven by the transmission drive member 310 to move along the first direction X to the first conveying mechanism 410, receive the iron core member 20 and the magnetic ring assembly 30, and move the iron core member 20 to the bottom of the press-fitting head 250; then, the output end of the jacking drive member 230 rises, passes through the first hollow portion 214 of the press-fitting base plate 211, the second hollow portion 321 of the transmission guide member 320 and the third hollow portion 331 of the carrying block 330, and rests against the bottom end of the motor shaft 10, and clamps the motor shaft 10 up and down with the press-fitting head 250, and descends synchronously to press the motor shaft 10 into the iron core member 20 below, thereby realizing the assembly of the motor shaft 10 and the iron core member 20.

[0043] In some embodiments, combined Figure 11The lifting drive member 230 plays the role of lifting the motor shaft 10 during the press-fitting process to prevent the motor shaft 10 from shaking. The output end of the lifting drive member 230 is connected to a first push rod 231, and the end of the first push rod 231 is provided with a first positioning cone 232 for positioning the end of the embedded motor shaft 10. The vertex of the first positioning cone 232 can be embedded in the end groove of the motor shaft 10 of different specifications, and the tapered side of the first positioning cone 232 increases the contact with the end of the motor shaft 10, further limiting the displacement of the motor shaft 10 in the horizontal plane.

[0044] In some embodiments, combined Figure 11 The lifting drive 230 is connected to a hollow first guide cylinder 233. The top end of the first guide cylinder 233 is mounted on the press-fitting base plate 211. The first guide cylinder 233 and the press-fitting head 250 are coaxially arranged vertically. The first guide cylinder 233 is used to guide the first push rod 231 through the first hollow portion 214 along the vertical direction Z. The first guide cylinder 233 directly restricts the first push rod 231 to move only in the vertical direction Z, completely eliminating lateral deviation or tilting of the first push rod 231 caused by uneven lifting force, excessive aspect ratio, easy bending, or slight deflection of the lifting drive 230.

[0045] In some embodiments, combined Figure 12 and Figure 13 The press-fitting head 250 includes a press-fitting cylinder 251 and a second push rod 252. The press-fitting cylinder 251 is mounted on the output end of the downward pressing driver 220, and the second push rod 252 is mounted on the press-fitting cylinder 251. The end of the second push rod 252 is provided with a second positioning cone 253 for positioning the end of the motor shaft 10. The vertex of the second positioning cone 253 can be embedded in the end groove of motor shafts 10 of different specifications. The tapered side of the second positioning cone 253 increases contact with the end of the motor shaft 10, further limiting the displacement of the motor shaft 10 in the horizontal plane, achieving automatic centering, and eliminating coaxiality errors.

[0046] In one embodiment, the press-fitting cylinder 251 has a positioning sleeve hole 254, which is used to movably sleeve the outer periphery of the end of the motor shaft 10, and can form an annular constraint from the radial direction of the motor shaft 10, forcing the motor shaft 10 to be corrected to a position coaxial with the press-fitting head 250.

[0047] In one embodiment, the second push rod 252 is installed in the positioning sleeve hole 254. After the motor shaft 10 enters the positioning sleeve hole 254, the circumferential position of the motor shaft 10 is stable, which is conducive to the alignment of the axis of the second push rod 252 with the axis of the motor shaft 10.

[0048] In one embodiment, the combination Figure 12 and Figure 13The press-fitting head 250 further includes a pressing elastic member 255. One end of the pressing elastic member 255 is mounted at the bottom of the positioning sleeve hole 254, and the other end of the pressing elastic member 255 is mounted at the top of the second push rod 252. When the end of the motor shaft 10 contacts the second push rod 252, the pressing elastic member 255 compresses as the second push rod 252 slightly retreats, adaptively offsetting the impact force during docking through elastic force. The pressing elastic member 255 can be a spring.

[0049] In one embodiment, the combination Figure 13 The output end of the clamping driver 240 is connected to a clamping block 241. The clamping driver 240 drives the clamping block 241 to move radially along the press-fitting head 250, thereby limiting the circumferential position of the motor shaft 10 without interfering with the axial force applied to the motor shaft 10. Furthermore, the clamping driver 240 controls the radial movement distance of the clamping block 241 to control the clamping force and accommodate motor shafts 10 of varying outer diameters.

[0050] In one embodiment, the clamping block 241 has a clamping shaft notch 242 , and the inner walls on opposite sides of the clamping shaft notch 242 are used to abut against the outer wall of the motor shaft 10 , which can disperse the clamping force to two contact areas and further limit the radial rotation and displacement of the motor shaft 10 .

[0051] In one embodiment, the combination Figure 13 A clamping and positioning block 260 is installed at the bottom of the press-fitting head 250. The clamping and positioning block 260 has a first accommodating through-hole 261 for accommodating the motor shaft 10. The clamping and positioning block 260 also has a second accommodating through-hole 262. One end of the second accommodating through-hole 262 is connected to the first accommodating through-hole 261, and the other end of the second accommodating through-hole 262 passes through the outer wall of the clamping and positioning block 260 along the radial direction of the press-fitting head 250. The second accommodating through-hole 262 is used to allow the clamping block 241 to move radially through. The first accommodating through-hole 261 limits the circumferential position of the motor shaft 10, further preventing the axis of the motor shaft 10 from being offset, and at the same time ensuring that the axis of the motor shaft 10 will not shake when the clamping block 241 clamps the motor shaft 10. The second accommodating through-hole 262 provides a rigid guide for the radial movement of the clamping block 241, thereby improving the movement stability of the clamping block 241. The clamping block 241 is completely hidden in the second accommodating through-hole 262 to prevent the clamping block 241 from being interfered with externally.

[0052] In one embodiment, there are two clamping drive members 240, and the two clamping drive members 240 are arranged opposite to each other along the radial direction of the press-fitting head 250 so that the output ends of the two clamping drive members 240 are closed to each other to form a symmetrical clamping force to prevent the motor shaft 10 from being offset by force.

[0053] In one embodiment, the side of the press head 250 has a mounting plane 256, and the clamping drive member 240 is installed in close contact with the mounting plane 256, which provides an installation reference for the clamping drive member 240. The plane has a large contact area, thereby improving the installation stability of the clamping drive member 240.

[0054] In one embodiment, the press-fitting head 250 is connected to a positioning rod 270 that extends downward in the vertical direction Z and is exposed below the press-fitting head 250. The positioning rod 270 is used to position the core member 20 and prevent the core member from rotating during the press-fitting process. In particular, when assembling multiple core members 20 on a motor shaft 10, or when sequentially press-fitting core members 20 and magnetic ring assemblies 30, the positioning rod 270 maintains the circumferential position of the first core member 20 between multiple press-fits, preventing deviation in the installation angle of the core member 20.

[0055] In one embodiment, the press-fitting device 200 further includes a first photoelectric sensor 281 mounted on the press-fitting column 213. The first photoelectric sensor 281 detects the carrier block 330 in the second direction Y. The detection height of the first photoelectric sensor 281 is 5 mm to 50 mm above the top surface of the carrier block 330. The first photoelectric sensor 281 is used to detect whether the carrier block 330 is carrying a component to be assembled, thereby facilitating confirmation of the activation of the lifting drive 230 and the pressing drive 220. The press-fitting process may generate debris such as metal debris and dust. If the detection height is less than 5 mm, the accumulation of debris can easily trigger false detections.

[0056] In one embodiment, the press-fitting device 200 further includes a second photoelectric sensor 282 mounted on the press-fitting column 213. The second photoelectric sensor 282 detects whether the press-fitting head 250 has descended to a preset height in the second direction Y. When the press-fitting head 250 descends to the preset height, the second sensor detects the presence of the press-fitting head 250 and immediately sends a signal to the controller, triggering the press-fitting head 250 to stop descending or switch to another position, thereby preventing damage to components caused by excessive descent of the press-fitting head 250.

[0057] In one embodiment, the combination Figure 1 The press-fitting device 200 further includes a code reader 283 , which is mounted on the press-fitting column 213 . The code reader 283 is used to scan the motor shaft 10 located on the carrier block 330 .

[0058] In one embodiment, the combination Figure 11The pressing device 200 also includes a pressure sensor 284, which is installed on the pressing head 250. The pressure sensor 284 is used to detect the pressing force of the pressing head 250. The pressure sensor 284 can collect the force value changes during the pressing process in real time and feed back the data to the controller to ensure that the pressing force is always within the preset process range and ensure the consistency of assembly quality. Among them, the pressure sensor 284 records the force-displacement curve throughout the process and stores it in conjunction with the identity information of the motor shaft 10 (obtained through the code reader 283). Production management personnel can optimize process parameters (such as adjusting the pressing speed and correcting the target force value) by analyzing batch force curves. For example, if the average pressing force of a batch of motor shafts 10 is found to be too high, it can be traced back to the large shaft diameter tolerance, and then feedback can be given to the upstream processing link for adjustment.

[0059] In some embodiments, the number of the press-fitting conveying mechanisms 300 is at least two, and the at least two press-fitting conveying mechanisms 300 are parallel and spaced along the second direction Y to achieve parallel operation, thereby significantly improving the production capacity per unit time.

[0060] In one embodiment, each press-fitting conveyor mechanism 300 corresponds to a pressing drive 220, a lifting drive 230, a clamping drive 240, and a press-fitting head 250. When each press-fitting conveyor mechanism 300 is equipped with an independent press-fitting head 250, multiple press-fitting conveyor mechanisms 300 can operate synchronously and independently without interfering with each other. The pressing drive 220, the lifting drive 230, the clamping drive 240, and the press-fitting head 250 share a press-fitting bracket 210, reducing the size of the press-fitting device 200 and improving its integrity and modularity.

[0061] Specifically, there are two press-fitting conveyor mechanisms 300, with their ends aligned in the first direction X. Correspondingly, there are two pressing drive members 220, two lifting drive members 230, two clamping drive members 240, and two press-fitting heads 250. Both the first transport mechanism 410 and the second transport mechanism 420 are capable of simultaneously transporting two components. Specifically, the first transport mechanism 410 simultaneously grabs two core members 20 and places them on the carrying blocks 330 of the two press-fitting conveyor mechanisms 300, respectively. It also simultaneously grabs two magnetic ring assemblies 30 and places them on the carrying blocks 330 of the two press-fitting conveyor mechanisms 300, respectively. The second transport mechanism 420 simultaneously grabs two motor shafts 10 and places them on the carrying blocks 330 of the two press-fitting conveyor mechanisms 300, respectively. Optionally, the two pressing drive members 220, the lifting drive member 230, and the clamping drive member 240 move synchronously to avoid uneven wear of the press-fitting device 200 due to a single workstation bearing a greater load for a long period of time.

[0062] In some embodiments, combined Figure 9 、 Figure 14 and Figure 15The carrier block 330 includes a first conveying block 340 and a second conveying block 350. The first conveying block 340 and the second conveying block 350 are sequentially arranged along the first direction X. The first conveying block 340 is closer to the first transport mechanism 410 than the second conveying block 350. The first conveying block 340 is used to place the magnetic ring assembly 30 and at least two core members 20. The first conveying block 340 is provided with at least two core positioning pin groups 341 and a magnetic ring positioning hole 342 spaced apart in sequence along the first direction X. Both the first conveying block 340 and the second conveying block 350 have a third hollow portion 331.

[0063] Based on this, the first transport mechanism 410, the press-fitting device 200, and the second transport mechanism 420 are spaced apart along the first direction X. The first transfer block 340 is used to dock with the first transport mechanism 410, and the second transfer block 350 is used to dock with the second transport mechanism 420. This shortens the sliding stroke of the carrier block 330 and improves operational efficiency. The core positioning pin assembly 341 prevents the core member 20 from rotating during movement of the carrier block 330, and the magnetic ring positioning hole 342 ensures precise positioning of the magnetic ring assembly 30 on the first transfer block 340.

[0064] Specifically, the core positioning pin group 341 is two cylindrical pins distributed in a straight line at intervals.

[0065] In one embodiment, the magnetic ring positioning hole 342 is located at the end of the first transfer block 340 near the first transport mechanism 410 to match the assembly sequence of the rotor assembly. Therefore, the first transfer block 340 moves along the first direction X toward the press-fitting head 250, and the multiple core members 20 are sequentially assembled onto the motor shaft 10, and finally the magnetic ring assembly 30 is assembled onto the motor shaft 10.

[0066] In one embodiment, all core positioning pin groups 341 are sequentially rotated about the vertical direction Z at a preset angle, thereby allowing multiple core members 20 to be press-fitted onto the same motor shaft 10 at a preset angle and in staggered stages. In one embodiment, the second conveyor block 350 is used to place the motor shaft 10, allowing the motor shaft 10 and the core members 20 to be loaded separately.

[0067] In some embodiments, the transfer drive 310 includes a first drive 311 and a second drive 312. The first drive 311 is used to drive the first transfer block 340, and the second drive 312 is used to drive the second transfer block 350. Independent driving allows the first and second transfer blocks 340 and 350 to move in parallel, improving press-fitting efficiency.

[0068] In one embodiment, the combination Figure 14The first driving member 311 and the second driving member 312 are respectively located on opposite sides of the conveying guide 320 in the second direction Y. On the one hand, the first driving member 311 and the second driving member 312 are located on opposite sides of the conveying guide 320. The forces generated during driving will offset each other in the second direction Y, resulting in a balanced force on the entire conveying guide 320 without any additional eccentric torque. On the other hand, the design of the first driving member 311 and the second driving member 312 on both sides can disperse the installation space of the first driving member 311 and the second driving member 312 to the left and right sides of the conveying guide 320, fully utilizing the space in the second direction Y.

[0069] In one embodiment, the combination Figure 14 The conveying guide 320 is a slide rail, and the conveying drive 310 drives the carrying block 330 to slide along the first direction X. The conveying guide 320 is stationary, and the second hollow portion 321 is stationary, maintaining vertical overlap with the first hollow portion 214. It is understood that in other embodiments, the conveying guide 320 is a conveyor belt, and the conveying drive 310 drives the conveyor belt to rotate, thereby driving the carrying block 330 to move along the first direction X. The second hollow portion 321 of the conveying guide 320 and the third hollow portion 331 of the carrying block 330 overlap vertically, and together move along the first direction X until they overlap vertically with the first hollow portion 214, thereby allowing the output end of the lifting drive 230 to pass through.

[0070] In some embodiments, combined Figure 1 and Figure 9 The magnetic ring press assembly machine includes a shaft loading mechanism 510 mounted on the frame 100. This mechanism is used to transport a shaft insertion plate 520 along the second direction Y. Multiple motor shafts 10 are inserted into the shaft insertion plate 520, enabling centralized batch loading and significantly improving loading efficiency. This directly addresses the issues of low loading efficiency and the risk of collisions with individual shafts. The shaft loading mechanism 510 is located to one side of the press assembly conveyor mechanism 300 in the second direction Y, fully utilizing the space in the second direction Y and reducing the machine's size in the first direction X, thus constricting the overall machine footprint.

[0071] Optionally, the magnetic ring press includes an axle feed trolley 530, which docks with the axle feeding mechanism 510 on the side of the axle feeding mechanism 510 away from the press-fitting transmission mechanism 300 to avoid interfering with the press-fitting and is away from the press-fitting working area, thereby protecting the safety of feeding.

[0072] In some embodiments, combined Figure 1 and Figure 9The shaft loading mechanism 510, the second transport mechanism 420, and the press-fitting conveyor mechanism 300 are sequentially spaced apart along the second direction Y. The second transport mechanism 420 directly grabs the motor shaft 10 at the output end of the shaft loading mechanism 510 without adjusting the grabbing direction. It moves horizontally from the shaft loading mechanism 510 to the press-fitting conveyor mechanism 300 along the second direction Y. After grabbing, the motor shaft 10 only needs to be moved a short distance to be placed on the carrying block 330 of the press-fitting conveyor mechanism 300, thereby improving work efficiency.

[0073] In one embodiment, the magnetic ring press machine also includes a first visual detector 540 installed on the frame 100. The first visual detector 540 is located between the shaft feeding mechanism 510 and the press-fitting conveying mechanism 300. The first visual detector 540 is used to detect the appearance quality of the motor shaft 10. Based on this, the motor shaft 10 with appearance defects is intercepted in advance by the first visual detector 540 to prevent defective products from flowing into subsequent processes and ensure assembly quality. In addition, the first visual detector 540 replaces manual visual inspection, improves inspection efficiency and consistency, and adapts to the automated rhythm. The first visual detector 540 is located between the shaft feeding mechanism 510 and the press-fitting conveying mechanism 300. After the second transport mechanism 420 grabs the motor shaft 10 from the shaft feeding mechanism 510, it needs to move to the press-fitting conveying mechanism 300. This moving path passes through the inspection area of ​​the first visual detector 540. The first visual detector 540 simultaneously completes shooting and analysis to improve inspection efficiency.

[0074] In one embodiment, the combination Figure 1 The magnetic ring press machine also includes a first recovery mechanism 550 mounted on the frame 100. The movement trajectory of the second transport mechanism 420 passes through the first recovery mechanism 550, and the detection range of the first visual inspection device 540 covers the upper part of the first recovery mechanism 550. Based on this, after the second transport mechanism 420 grabs the motor shaft 10 from the shaft loading mechanism 510, it must move to the press-fitting conveyor mechanism 300 and must pass through the first recovery mechanism 550. At this time, the motor shaft 10 is inspected by the first visual inspection device 540. If it passes, it continues to move to the press-fitting conveyor mechanism 300. If it fails, it is placed in the first recovery mechanism 550 and returns to grab the next motor shaft 10, improving the efficiency of loading and inspection.

[0075] In one embodiment, the combination Figure 1The first visual inspection device 540 and the first recovery mechanism 550 are spaced apart along the first direction X. The motion trajectory of the second transport mechanism 420 needs to connect the shaft removal, inspection, and delivery of qualified shafts to press-fitting or delivery of defective shafts to recycling. If the first visual inspection device 540 and the first recovery mechanism 550 are spaced apart along the second direction Y, the second transport mechanism 420 needs to stop twice in the second direction Y, that is, first stop below the first visual inspection device 540 for inspection, and then stop above the first recovery mechanism 550 to place defective products, which increases the loading time cost. When the first visual inspection device 540 and the first recovery mechanism 550 are spaced apart along the first direction X, the second transport mechanism 420 only needs to stop once between the first visual inspection device 540 and the first recovery mechanism 550. If the inspection is qualified, it will continue to move, otherwise it will recycle the motor shaft 10. This makes the motion path simpler and avoids the rhythm conflict with other mechanisms.

[0076] In one embodiment, the combination Figure 1 The magnetic ring press assembly machine further includes a marking mechanism 560 mounted on the frame 100 , and the marking mechanism 560 is used to mark the motor shaft 10 to realize information management of the production process.

[0077] In one embodiment, the marking mechanism 560 is located between the shaft loading mechanism 510 and the press-fitting conveying mechanism 300. The marking action is embedded in the transfer gap, eliminating the need for a separate marking movement path for marking, thereby improving work efficiency.

[0078] Specifically, the marking mechanism 560 is located between the first visual detector 540 and the press-fitting conveying mechanism 300. It only marks the motor shaft 10 that passes the visual inspection. The unqualified shaft is directly sent to the first recycling mechanism 550 by the second conveying mechanism 420, avoiding ineffective marking of the unqualified motor shaft 10 (wasting marking materials / time, and the need to clean up the labeled defective products during subsequent recycling), thereby improving work efficiency.

[0079] In some embodiments, combined Figure 1 The magnetic ring press machine further includes a blanking mechanism 800 mounted on the frame 100. The blanking mechanism 800 and the shaft loading mechanism 510 are both located at the same end of the press-fitting conveyor mechanism 300 in the first direction X. The blanking mechanism 800 and the shaft loading mechanism 510 are both located on opposite sides of the press-fitting conveyor mechanism 300 in the second direction Y. Firstly, this avoids increasing the size of the press-fitting conveyor mechanism in the first direction X. Secondly, this forms a symmetrical layout of single-side feeding and single-side blanking, avoiding space congestion caused by stacking different mechanisms on the same side. Thirdly, the magnetic ring assembly 30 and the core member 20 need to be loaded at the other end of the press-fitting conveyor mechanism 300. Therefore, placing the blanking mechanism 800 at the same end of the shaft loading mechanism 510 makes the layout more uniform.

[0080] In some embodiments, combined Figure 1The magnetic ring press assembly machine further includes an iron core feeding mechanism 600 installed on the frame 100, which supplies the iron core piece 20 along the second direction Y.

[0081] In one embodiment, the combination Figure 2 The magnetic ring loading mechanism 700, the press-fitting conveying mechanism 300 and the iron core loading mechanism 600 are spaced apart along the second direction Y, that is, the loading of the iron core piece 20 and the loading of the magnetic ring assembly 30 are respectively on both sides of the press-fitting conveying mechanism 300, avoiding loading interference and reducing the risk of mechanism collision. Moreover, the distribution along the second direction Y can maximize the use of the linear space of the frame 100 and reduce redundant space.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
