Description

Technical Field

[0001] This invention relates to the field of winding machine equipment technology, specifically to an automated winding processing equipment for motor stator coils. Background Technology

[0002] Motor stator coil winding processing equipment is widely used in the field of motor manufacturing. As the core basic component of a motor, the quality of its coil winding, the accuracy of its arrangement, and the state of its forming directly affect the motor's operational stability, insulation performance, and overall reliability. It is a crucial processing link in the motor production process.

[0003] Currently, most stator winding operations in the industry still rely on manual, single-machine processing. Workpiece transfer, clamping and positioning, wire winding, and finished product unloading all require manual operation. This is not only labor-intensive, but manual intervention also limits overall capacity. Furthermore, human error can easily lead to workpiece collisions, positioning misalignments, and uneven winding. Additionally, traditional equipment has limited adaptability; whenever switching product models, it's necessary to replace the corresponding tooling and re-align and adjust, which is time-consuming, labor-intensive, and results in significant production downtime, making it inefficient for handling small-batch, multi-variety production orders. Therefore, an automated stator coil winding processing equipment for motors is needed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automated winding processing equipment for motor stator coils, which solves the problems of high manual operation ratio, cumbersome production changeover and debugging, and insufficient production continuity.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An automated winding machine for motor stator coils includes: A workbench is provided, with a top frame fixedly connected to the top of the workbench. A rotary worktable is rotatably connected to the center of the top of the workbench. The rotary worktable is divided into four workstations along its circumference: a loading workstation, a positioning workstation, a winding workstation, and a unloading workstation. A rotating shaft is fixedly connected to the center of the bottom of the rotary worktable. A fixed frame is fixedly connected to the inner wall of the workbench. The outer wall of the rotating shaft is mounted in the fixed frame through bearings. A guide ring is fixedly connected to the top of the fixed frame. The rotating shaft is driven to rotate by a drive assembly, causing the rotary worktable to rotate intermittently, thereby realizing the automatic transfer of the motor stator ring between the workstations. The feeding conveyor belt is installed on the top of the workbench by a fixed bracket. A guide hopper is fixedly connected to the side wall of the discharge end of the feeding conveyor belt. The lower outlet of the guide hopper is directly opposite the loading station of the rotary worktable. A guide component is provided at the conveying end of the feeding conveyor belt to automatically push the motor stator ring into the guide hopper. Four positioning rods are respectively vertically installed at the four positions of the rotary worktable. Each positioning rod has a baffle for limiting the motor stator coil on its outer wall. Each positioning rod is rotatably connected to the rotary worktable. Each positioning rod has a positioning component inside, which is used to radially tighten the inner wall of the stator coil from the inside to prevent circumferential or axial displacement during the winding process. A reciprocating block is fixedly connected to the top of the rotary workstation. A reciprocating groove is provided on the outer wall of the reciprocating block. A lifting frame is embedded in the reciprocating groove of the reciprocating block. The outer wall of the lifting frame is slidably connected along the vertical direction of the top frame. The lifting frame is guided by the groove of the reciprocating block and realizes vertical reciprocating lifting with the intermittent rotation of the rotary workstation. A winding assembly is installed on the top right side of the workbench and is used to perform a fly fork winding operation on the motor stator rings in the winding station. The unloading rack is located at the top rear side of the workbench. Inside the unloading rack is an unloading component for grabbing the completed motor stator coil from the top of the positioning rod at the unloading station. Below the unloading rack is a synchronous feeding component for feeding the grabbed motor stator coil out of the equipment.

[0006] Preferably, the guiding assembly includes a lifting rod fixedly connected to the outer wall of the left side of the lifting frame. The bottom of the lifting rod is rotatably connected to a reciprocating rod via a connecting rod. The middle part of the reciprocating rod is slidably connected to the top shell of the feeding conveyor belt via a fixed bracket. A pusher plate is installed at the end of the reciprocating rod. The pusher plate is located on the side of the output end of the feeding conveyor belt and is used to push the motor stator ring into the guide hopper.

[0007] Preferably, the positioning assembly includes a base rotatably connected to the bottom of the positioning rod, the base being mounted on the outer wall of the guide ring, a slide rod slidably connected to the inner wall of the base, an inclined guide block being embedded in the top inner wall of the slide rod, and positioning blocks abutting each of the four inclined surfaces of the inclined guide block. The positioning blocks are slidably connected to the top of the positioning rod, and a return spring is provided at the top of each positioning block. The guide ring is provided with an inclined guide rail. When the slide rod rises through the inclined surface of the guide ring, the positioning block is pushed out and tightened against the inner wall of the stator. When resetting, the positioning block is contracted and released by the return spring.

[0008] Preferably, the top of the positioning rod is threaded with an adjusting rod, the bottom of the adjusting rod abuts against the inclined guide block, and a return spring is installed at the bottom of the inclined guide block. By rotating the adjusting rod, the height of its bottom end is changed, the initial position of the inclined guide block is adjusted, and the radial extension distance of the positioning block is changed to adapt to motor stator rings with different inner diameters.

[0009] Preferably, the winding assembly includes a second equipment compartment installed on the top right side of the workbench, a fly fork die head installed on the left side of the second equipment compartment for fly fork winding, and a threaded rod driven by a motor provided at the bottom of the second equipment compartment. When the threaded rod rotates, it drives the second equipment compartment to move horizontally along the top guide rail of the workbench to adjust the relative position of the fly fork die head and the motor stator ring.

[0010] Preferably, a second lifting rod is fixedly connected to the outer wall of the right side of the lifting frame, and an equipment compartment is fixedly connected to the bottom of the second lifting rod. A scissor bracket is installed between the equipment compartment and the top frame to improve lifting stability. A motor-driven indexing rod is installed on the right side of the equipment compartment to drive the positioning rod to rotate synchronously with the motor stator ring during winding. A movable frame controlled by a cylinder is slidably connected to the left side of the equipment compartment via a bracket. Two fixed plates for winding are fixedly connected to the bottom of the movable frame, and a shearing head for cutting wire is installed at the end of the rear support arm of the movable frame.

[0011] Preferably, the unloading assembly includes a lifting rod three fixedly connected to the outer wall of the rear side of the lifting frame, an unloading frame fixedly connected to the bottom end of the lifting rod three, the bottom of the unloading frame facing the unloading position of the rotary worktable, and a wedge block two slidably connected around the inner side of the bottom of the unloading frame. A return spring is installed on the side of the wedge block two near the unloading frame. When the unloading frame descends, the wedge block two abuts against the motor stator ring through the inclined surface and retracts outward. After descending to the position, the return spring causes the wedge block two to pop outward, supporting the end face of the motor stator ring from below to achieve clamping.

[0012] Preferably, each wedge block 1 is slidably connected to the inner wall of the unloading frame corresponding to the position of each wedge block 2 in the vertical direction. The lower end of each wedge block is embedded in the inclined groove of the inner wall of the wedge block 2. A return spring is installed on both sides of the wedge block 1. An unloading ring is fixedly connected to the rear side of the top of the top frame. Each unloading ring is provided with a guide rod corresponding to the position of the wedge block 1. When the unloading frame rises, the guide rod presses the wedge block 1 downward. The wedge block 1 drives the wedge block 2 to retract outward through the inclined groove, thereby releasing the clamped motor stator ring and completing the unloading.

[0013] Preferably, the feeding assembly includes a transmission rod located on the outer periphery of the rotating shaft and connected by a synchronous belt and synchronous pulley. Feeding plates are fixedly connected to both sides of the top of the transmission rod. The transmission rod drives the feeding plates to rotate synchronously, feeding the motor stator ring released from the unloading rack to the outside of the equipment.

[0014] Preferably, the drive assembly includes a cam that is circumferentially fixedly connected to the outer wall of the rotary worktable, and a motor-driven drive shaft is installed on the inner wall of the left side of the worktable. The cam is installed inside the drive shaft, and when the drive shaft rotates, it drives the rotary worktable to rotate intermittently through the cam.

[0015] Working principle: During the feeding and pushing stage, after the equipment is started, the drive shaft rotates under the drive of the motor, and drives the rotary station disk to rotate intermittently through the cam, realizing the periodic switching of the four stations. The feeding conveyor belt transports the motor stator ring to the output end. When the rotary station disk rotates, the reciprocating block fixed on its top rotates accordingly. The lifting frame moves vertically up and down along the top frame under the guidance of the reciprocating slide groove of the reciprocating block. The lifting rod on the left side of the lifting frame moves up and down synchronously with the lifting frame. The reciprocating rod is driven by the connecting rod to slide horizontally back and forth in the fixed bracket. When the lifting frame rises, the reciprocating rod drives the pusher plate forward, pushing the motor stator ring at the output end of the feeding conveyor belt into the guide hopper. The lower outlet of the guide hopper is directly opposite the feeding station. The stator ring falls onto the positioning rod of the feeding station by gravity, and its falling position is restricted by the baffle on the outer wall of the positioning rod. When the lifting frame descends, the reciprocating rod retracts, the pusher plate resets, and waits for the next cycle.

[0016] During the positioning and fixing stage, after the material is loaded, the rotary station disk rotates the stator ring to the positioning station. The guide ring at the top of the fixing frame is equipped with an inclined guide rail. When the rotary station disk rotates to the positioning station, the lower end of the sliding rod at the bottom of the positioning rod contacts the inclined surface of the guide ring and is gradually lifted. The sliding rod slides upward within the positioning rod and the base, and the inclined guide block at its top rises accordingly. The four inclined surfaces of the inclined guide block push the four positioning blocks to slide outward radially, overcoming the elastic force of the return spring at the top of the positioning block, and tightening the inner wall of the motor stator ring from the inside. The initial height of the inclined guide block can be changed by pre-rotating the adjusting rod, thereby adjusting the radial extension distance of the positioning block to accommodate stator rings with different inner diameters. After positioning, the stator ring is firmly fixed on the positioning rod to prevent deviation during the winding process.

[0017] During the winding operation, after positioning, the rotary worktable rotates the stator ring to the winding position. The lifting rod on the right side of the lifting frame lowers the equipment compartment to the working position. The scissor bracket ensures smooth lifting. The indexing rod is fixedly sleeved on the positioning rod of the winding position to vertically position the motor stator ring. The cylinder on the left side of equipment compartment one controls the extension and retraction of the moving frame, bringing the two fixed plates at the bottom closer to the motor stator ring to assist in guiding the wire. The motor at the bottom of equipment compartment two drives the threaded rod to rotate, causing equipment compartment two to move horizontally along the guide rail, adjusting the fly fork die head to align with the winding position of the stator ring, and starting the winding. At the same time, the motor on the right side of equipment compartment one drives the indexing rod to rotate. Through the transmission cooperation between the indexing rod and the positioning rod, the positioning rod and the motor stator ring rotate synchronously to achieve indexing during the winding process. The fly fork die head rotates at high speed to wind the wire onto the stator ring. After winding is completed, the shear head at the end of the rear support arm of the moving frame moves to cut the wire.

[0018] During the unloading and feeding stages, after winding is completed, the rotary station plate rotates the finished stator ring to the unloading station. The lifting rod three on the rear side of the lifting frame drives the unloading frame to descend. The wedge block two on the inner side of the bottom of the unloading frame first contacts the upper edge of the stator ring. The inclined surface of the wedge block two is squeezed outward by the stator ring and retracts. After the unloading frame continues to descend to the set position, the wedge block two pops outward under the action of the return spring, supporting the end face of the stator ring from below and completing the clamping. Then the lifting rod three drives the unloading frame to rise. When the unloading frame rises to the top, the guide rod fixed on the unloading ring on the rear side of the top frame squeezes the wedge block one downward. The wedge block one moves downward in the vertical direction, and its lower end drives the wedge block two to retract outward through the inclined groove, thereby releasing the stator ring. The removed stator rings fall onto the feeding assembly below. At the same time, the rotating shaft drives the transmission rod to rotate via the synchronous belt and synchronous pulley. The feeding plate at the top of the transmission rod rotates synchronously with it, pushing the stator rings released from the unloading rack to the outside of the equipment, thus completing the collection of finished products.

[0019] This invention provides an automated winding processing device for motor stator coils. It has the following advantages: 1. This invention achieves process integration design by adopting a four-station rotary layout, integrating the functions of feeding, positioning, winding, and unloading into one, getting rid of the traditional separate equipment processes. The whole set of equipment relies on mechanical structure to achieve full-process linkage operation, reducing manual intervention links, effectively reducing labor input costs, and the continuous operation mode can improve the overall production cycle, which is suitable for large-volume stator coil processing scenarios.

[0020] 2. The present invention has a built-in radial expansion positioning structure, which can complete multi-point centering and fixing from inside the workpiece. When combined with the indexing rotating rod of the winding station, it can effectively avoid the problem of circumferential slippage and axial displacement of the stator during the winding process. At the same time, the positioning structure can flexibly change the extension range of the positioning component, which can be adapted to the processing of motor stator rings with different inner diameter specifications.

[0021] 3. The integrated automatic feeding and gripping unloading structure of this invention automates the entire process of workpiece transfer, clamping, and release. The mechanical transmission and linkage method have strong anti-interference capabilities, enabling long-term stable and continuous operation. This reduces the frequency of equipment inspection and maintenance, lowers equipment operation and maintenance costs, and has high space utilization. The overall equipment occupies a small area, making it convenient for workshop site planning and placement. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example: This invention provides an automated winding processing equipment for motor stator coils, comprising: Please see the appendix Figure 3 Appendix Figure 4 and attachedFigure 8 The workbench 1 has a top frame 2 fixedly connected to its top. A rotary workstation 3 is rotatably connected to the center of the top of the workbench 1. The rotary workstation 3 is divided into four stations along its circumference: a loading station, a positioning station, a winding station, and a unloading station. A rotating shaft 11 is fixedly connected to the center of the bottom of the rotary workstation 3. A fixed frame 12 is fixedly connected to the inner wall of the workbench 1. The outer wall of the rotating shaft 11 is mounted in the fixed frame 12 via bearings. A guide ring 13 is fixedly connected to the top of the fixed frame 12. The rotating shaft 11 is driven to rotate by a drive assembly, which includes components circumferentially fixed to the outer wall of the rotary workstation 3. The cam 9 is installed inside the drive shaft 10 driven by a motor on the inner wall of the left side of the worktable 1. When the drive shaft 10 rotates, the cam 9 drives the rotary station disk 3 to rotate intermittently, realizing the automatic transfer of the motor stator ring between each station. The top of the rotary station disk 3 is fixedly connected to a reciprocating block 14. The outer wall of the reciprocating block 14 is provided with a reciprocating slide groove. The reciprocating slide groove of the reciprocating block 14 is embedded in the lifting frame 15. The outer wall of the lifting frame 15 is slidably connected along the vertical direction of the top frame 2. The lifting frame 15 is guided by the slide groove of the reciprocating block 14 and realizes vertical reciprocating lifting with the intermittent rotation of the rotary station disk 3.

[0026] Specifically, the motor of the drive shaft 10 is started, and the drive shaft 10 drives the rotary station disk 3 to rotate intermittently through the cam 9. The single rotation angle is 90°, forming a four-station cyclic operation rhythm. The rotating shaft 11 at the bottom of the rotary station disk 3 will rotate synchronously on the fixed frame 12. The lifting frame 15 rotates with the rotary station disk 3 and is guided by the slide groove of the reciprocating block 14 to rise and fall vertically along the top frame 2, thereby continuously switching the position of the rotary station disk 3, and thus realizing continuous automated winding processing.

[0027] Please see the appendix Figure 5 - Appendix Figure 7 The feeding conveyor belt 4 is installed on the top of the workbench 1 by a fixed bracket. A guide hopper 8 is fixedly connected to the side wall of the discharge end of the feeding conveyor belt 4. The lower outlet of the guide hopper 8 is directly opposite the loading position of the rotary worktable 3. A guide assembly is provided at the conveying end of the feeding conveyor belt 4 to automatically push the motor stator ring into the guide hopper 8. The guide assembly includes a lifting rod 7 fixedly connected to the outer wall on the left side of the lifting frame 15. The bottom of the lifting rod 7 is rotatably connected to a reciprocating rod 6 through a connecting rod. The middle part of the reciprocating rod 6 is slidably connected to the top shell of the feeding conveyor belt 4 through a fixed bracket. A pusher plate 5 is installed at the end of the reciprocating rod 6. The pusher plate 5 is located on the side of the output end of the feeding conveyor belt 4 to push the motor stator ring into the guide hopper 8.

[0028] Specifically, when the rotary station disk 3 rotates and the lifting frame 15 rises, the lifting rod 7 rises synchronously with the lifting frame 15. Its bottom connecting rod lever drives the reciprocating rod 6 to slide horizontally forward in the fixed bracket. The pusher plate 5 pushes the motor stator ring at the output end of the feeding conveyor belt 4 into the guide hopper 8. The motor stator ring falls along the guide hopper 8 and is fitted onto the positioning rod 18 at the loading station. When the rotary station disk 3 continues to rotate, the lifting frame 15 descends, and the reciprocating rod 6 drives the pusher plate 5 to reset backward, waiting for the next cycle.

[0029] Please see the appendix Figure 9 - Appendix Figure 11 Four positioning rods 18 are vertically installed at the four positions of the rotary worktable 3. Each positioning rod 18 has a baffle on its outer wall for limiting the motor stator coil. Each positioning rod 18 is rotatably connected to the rotary worktable 3. Each positioning rod 18 has a positioning component inside, which is used to radially tighten the inner wall of the stator coil from the inside to prevent circumferential or axial displacement during winding. The positioning component includes a base 19 rotatably connected to the bottom of the positioning rod 18. The base 19 is installed on the outer wall of the guide ring 13. A slide rod 21 is slidably connected to the inner wall of the positioning rod 18 and the base 19. An inclined guide block 23 is embedded in the top inner wall of the slide rod 21. The four inclined surfaces of the inclined guide block 23 abut against each other. There is a positioning block 20, which is slidably connected to the top of the positioning rod 18. Each positioning block 20 is equipped with a return spring at its top. The guide ring 13 is equipped with an inclined guide rail. When the guide rod 21 rises through the inclined surface of the guide ring 13, it pushes the positioning block 20 out and tightens the inner wall of the stator. When resetting, the return spring causes the positioning block 20 to contract and loosen. The top of the positioning rod 18 is threadedly connected to an adjusting rod 22. The bottom of the adjusting rod 22 abuts against the inclined guide block 23. The bottom of the inclined guide block 23 is equipped with a return spring. By rotating the adjusting rod 22, the height of its bottom end is changed, the initial position of the inclined guide block 23 is adjusted, and the radial extension distance of the positioning block 20 is changed to adapt to motor stator rings with different inner diameters.

[0030] Specifically, when the rotary station disk 3 rotates the positioning rod 18 with the stator ring into the positioning station, the lower end of the slide rod 21 contacts the inclined guide rail of the guide ring 13 and is gradually lifted. The slide rod 21 slides upward, driving the inclined guide block 23 to rise. The four inclined surfaces of the inclined guide block 23 push the four positioning blocks 20 outward radially, overcoming the return spring force at the top of the positioning block 20, and tightening the inner wall of the stator ring from the inside to achieve centering and axial fixation. By rotating the adjusting rod 22 to change its bottom height, the initial position of the inclined guide block 23 can be adjusted, thereby adjusting the radial extension distance of the positioning block 20 to adapt to motor stator rings with different inner diameters. When the rotary station disk 3 continues to rotate to the unloading station, when the slide rod 21 disengages from the inclined surface of the guide ring 13, the return spring at the bottom of the inclined guide block 23 and the return spring at the top of each positioning block 20 cause the positioning block 20 to contract and loosen.

[0031] Please see the appendix Figure 12 - Appendix Figure 14 The winding assembly is installed on the top right side of the workbench 1 and is used to perform fly fork winding operations on the motor stator ring in the winding position. The winding assembly includes a second equipment compartment 26 installed on the top right side of the workbench 1. A fly fork die head 24 is installed on the left side of the second equipment compartment 26 for fly fork winding. A threaded rod driven by a motor is provided at the bottom of the second equipment compartment 26. When the threaded rod rotates, it drives the second equipment compartment 26 to move horizontally along the top guide rail of the workbench 1 to adjust the relative position of the fly fork die head 24 and the motor stator ring. A second lifting rod is fixedly connected to the outer wall of the right side of the lifting frame 15. 16. The bottom of the lifting rod 16 is fixedly connected to the equipment compartment 25. A scissor bracket is installed between the equipment compartment 25 and the top frame 2 to improve the lifting stability. The right side of the equipment compartment 25 is equipped with an indexing rod 30 driven by a motor, which is used to drive the positioning rod 18 to rotate synchronously with the motor stator ring when winding. The left side of the equipment compartment 25 is slidably connected to a movable frame 27 controlled by a cylinder for telescopic movement via a bracket. The bottom of the movable frame 27 is fixedly connected to two fixing plates 29 for winding. A shearing head 28 for cutting wire is installed at the end of the rear support arm of the movable frame 27.

[0032] Specifically, after the stator ring enters the winding position, the motor-driven threaded rod at the bottom of the second equipment compartment 26 rotates, causing the second equipment compartment 26 to move horizontally along the guide rail, adjusting the flying fork die head 24 to align with the winding position of the stator ring. At the same time, the lifting rod 26, along with the lifting frame 15, drives the first equipment compartment 25 to descend to the working position. The scissor bracket ensures smooth lifting. The motor-driven indexing rod 30 on the right side of the first equipment compartment 25 rotates, and through the transmission cooperation with the positioning rod 18, drives the positioning rod 18 to rotate synchronously with the motor stator ring, realizing indexing during the winding process. The cylinder on the left side of the first equipment compartment 25 controls the extension of the moving frame 27, so that the two fixed plates 29 are close to the winding area to assist in guiding the wire. The flying fork die head 24 rotates at high speed, winding the wire onto the stator ring. After the winding is completed, the shearing head 28 cuts the wire, and then the moving frame 27 retracts, and the first equipment compartment 25 rises to reset.

[0033] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 15The unloading rack 31 is located at the top rear side of the workbench 1. An unloading assembly is installed inside the unloading rack 31 to grab the completed motor stator coil from the top of the positioning rod 18 at the unloading position. A synchronous feeding assembly is located below the unloading rack 31 to deliver the grabbed motor stator coil out of the equipment. The unloading assembly includes a lifting rod 17 fixedly connected to the outer wall of the lifting frame 15 at the rear side. The bottom end of the lifting rod 17 is fixedly connected to the unloading rack 31. The bottom of the unloading rack 31 faces the unloading position of the rotary workbench 3. Wedge blocks 34 are slidably connected around the inner perimeter of the bottom of the unloading rack 31. A return spring is installed on the side of the wedge blocks 34 near the unloading rack 31. When the unloading rack 31 descends, the wedge blocks 34 abut against the motor stator coil through their inclined surfaces and retract outwards. After descending to the correct position, the return spring causes the wedge blocks 34 to pop inwards, supporting the end face of the motor stator coil from below. To achieve clamping, wedge blocks 33 are slidably connected vertically to the inner walls of each wedge block 34 on the unloading rack 31. The lower end of each wedge block 33 is embedded in the inclined groove on the inner wall of each wedge block 34. Return springs are installed on both sides of each wedge block 33. An unloading ring 32 is fixedly connected to the rear side of the top of the top frame 2. Guide rods are provided on each wedge block 33 on the unloading ring 32. When the unloading rack 31 rises, the guide rods press down on the wedge blocks 33. The wedge blocks 33 drive the wedge blocks 34 to retract outward through the inclined grooves, thereby releasing the clamped motor stator ring and completing the unloading. The feeding assembly includes a transmission rod 36 located on the outer periphery of the rotating shaft 11 and connected by a synchronous belt and synchronous pulley. Feeding plates 35 are fixedly connected to both sides of the top of the transmission rod 36. The transmission rod 36 drives the feeding plates 35 to rotate synchronously, sending the motor stator ring released from the unloading rack 31 to the outside of the equipment.

[0034] Specifically, after the finished stator ring is wound and transferred to the unloading station, the lifting rod 317 moves down with the lifting frame 15, causing the unloading frame 31 to descend. The wedge block 34 first contacts the upper edge of the stator ring, and its inclined surface is squeezed outward, compressing the return spring. After the unloading frame 31 continues to descend to the set position, the return spring causes the wedge block 34 to pop inward, supporting the end face of the stator ring from below, completing the clamping. Then, the lifting rod 317 drives the unloading frame 31 to rise. When the unloading frame 31 rises to the top, the guide rod on the unloading ring 32 presses the wedge block 33 downward. The wedge block 33 moves down in the vertical direction, and its lower end drives the wedge block 34 to retract outward through the inclined groove, releasing the clamped motor stator ring. The stator ring falls into the feeding plate 35 below. The rotating shaft 11 drives the transmission rod 36 to rotate through the synchronous belt and synchronous pulley. The feeding plate 35 at the top of the transmission rod 36 rotates synchronously, pushing the released motor stator ring to the outside of the equipment.
