Description

Technical Field

[0001] This invention relates to a universal motor stator flat wire end rotary cutting and pushing machine and its configuration method. Background Technology

[0002] Currently, after the flat wire motor stator is wound, the ends of the flat wire need to be trimmed flat. Existing trimming equipment typically uses multiple push cutters in conjunction with a fixed cutter disc to cut the flat wire ends by radially pushing the push cutters.

[0003] A search revealed that Chinese invention patent application CN120566832A discloses a push-cutting device for flattening flat wire ends of motor stators. This device includes a fixed blade holder, positioning plates, and a radial pushing assembly. The fixed blade holder has a fixed number of push-cutting channels, and the positioning plates have a corresponding number of positioning holes. The push-cutting blades and push-cutting channels, as well as the positioning holes and flat wire ends, have a one-to-one correspondence. However, the layout of the fixed blade holder, positioning plates, and push-cutting blades in the aforementioned prior art is fixedly designed based on the number of slots in a specific motor (e.g., 54 slots). When it is necessary to produce a motor with a different number of slots (e.g., 72 slots), the distribution of the number of positioning holes and the position of the push-cutting channels cannot match, requiring the replacement of the entire fixed blade holder and related components. This results in the equipment being incompatible with motors of two different slot numbers, exhibiting poor versatility and high changeover costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a universal motor stator flat wire end rotary cutting and pushing machine and its configuration method, which can simultaneously accommodate the cutting and flattening operations of various motors with different slot numbers, thereby improving the versatility of the equipment.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: a universal motor stator flat wire end rotary cutting and pushing machine, comprising: frame; A transfer mechanism is mounted on the frame. The transfer mechanism is provided with a carrying platform and a clamping part mounted on the carrying platform. The clamping part is adapted to clamp the motor stator. When the clamping part moves with the carrying platform, it switches between a push-cutting station and a rotary-cutting station to transfer the motor stator. A rotary cutting mechanism is mounted on the frame and corresponding to the rotary cutting station. The rotary cutting mechanism includes a rotary cutting drive and a rotary cutting cutter. When the rotary cutting drive rotates, it drives the rotary cutting cutter to rotate around the rotary cutting axis. When the motor stator is located at the rotary cutting station, the rotary cutting cutter contacts and cuts the flat wire end of the motor stator. A push-cutting mechanism is mounted on the frame and is set corresponding to the push-cutting station. The push-cutting mechanism includes a cutter disc, a cutter group, a limiting cutter groove plate, a feed drive mechanism, and a cutter disc rotation drive mechanism. The cutter disc is rotatably mounted on the frame around its central axis, and the limiting blade groove plate is mounted on the cutter disc and rotates synchronously with the cutter disc. The cutting blade assembly is divided into N equal circumferential partitions around the central axis, and the equal circumferential partitions N is the greatest common factor of the number of slots applicable to at least two different motor stators with different slot numbers; The cutting blade group includes a first type of cutting blade and a second type of cutting blade, with N first type of cutting blades and N second type of cutting blades, which are evenly distributed in a staggered manner along the circumference, such that at least one first type of cutting blade and at least one second type of cutting blade are provided in each of the circumferential equal partitions; The limiting tool slot plate is provided with a slot array corresponding to the currently processed motor stator slot; the first type of cutter and the second type of cutter are respectively inserted through the slot array and move radially under the limiting of the slot array; The rotary drive mechanism for the cutting disc is mounted on the frame and is connected to the cutting disc in a transmission manner. When the rotary drive mechanism for the cutting disc is activated, it drives the cutting disc, the limiting blade groove plate, and the cutting blade assembly to rotate around the central axis and can stop at the first rotary station and the second rotary station. The feed drive mechanism is mounted on the frame and is provided with a pushing member. The pushing member has multiple pushing parts distributed circumferentially. When the feed drive mechanism is activated, it drives the pushing member to reciprocate along the feed direction. When the cutting disc is driven to rotate to the first rotating station by the cutting disc rotation drive mechanism, the pushing part is aligned with and abuts against the first type of cutting blade. When the pushing part moves along the feed direction, it drives the first type of cutting blade to move radially to push and cut the end of the flat wire. When the cutter disc is driven to rotate to the second rotating position by the cutter disc rotation drive mechanism, the pushing part aligns with and abuts against the second type of cutter. When the pushing part moves along the feed direction, it drives the second type of cutter to move radially to push and cut the end of the flat wire.

[0006] Furthermore, the universal motor stator flat wire end rotary cutting and pushing integrated machine also includes a motor production conveyor line, which is provided with a connecting position; The transfer mechanism includes a lifting assembly, a tilting mechanism, and a clamping mechanism. The lifting assembly is mounted on the bearing platform, the tilting mechanism is mounted on the lifting assembly, and the clamping mechanism is mounted on the tilting mechanism. The clamping part is disposed on the clamping mechanism.

[0007] Furthermore, the universal motor stator flat wire end rotary cutting and pushing machine also includes a pressing mechanism. The pressing mechanism is set on the bearing platform. The pressing mechanism is equipped with a pressing head and a pressing drive. When the pressing drive is activated, it drives the pressing head to press down in the vertical direction and contact the upper end face of the motor stator, so as to apply a downward clamping force to the motor stator during pushing or rotary cutting.

[0008] Furthermore, the limiting slot plate includes at least two types of limiting slot plates with different slot distributions, and the corresponding limiting slot plates are respectively set to the circumferential position of the flat wire end of the motor stator with the corresponding number of slots.

[0009] Furthermore, the effective cutting width of the first type of cutter is greater than that of the second type of cutter, and the effective cutting width of the first type of cutter is suitable for covering the flat wire end area corresponding to at least one adjacent slot, while the effective cutting width of the second type of cutter is suitable for covering the flat wire end area corresponding to a single slot.

[0010] Furthermore, the general-purpose motor stator flat wire end rotary cutting and pushing integrated machine also includes an annular blade changing limiting ring, which is fixedly installed on the frame and located between the pushing member and the cutting blade group; The annular tool changing limiting ring is provided with multiple selection slots spaced apart along the circumference, and the first type of cutter and the second type of cutter are respectively provided with matching slots corresponding to the annular tool changing limiting ring; The pushing member is adapted to abut against the first type of cutter or the second type of cutter when the cutter is located in the selection slot, thereby driving the corresponding first type of cutter or the second type of cutter to move radially.

[0011] Furthermore, the pressing part is also provided with a return hook, which is adapted to engage with the mating groove and drive the corresponding first type of cutter or the second type of cutter to return radially when the pressing component returns.

[0012] This invention also discloses a method for using a universal motor stator flat wire end rotary cutting and pushing machine, which employs the aforementioned universal motor stator flat wire end rotary cutting and pushing machine: S1. The motor stator enters through the connection point via the motor production conveyor line. The transfer mechanism clamps the motor stator and sends it to the push-cutting station, including the following steps: S2, Pressing mechanism presses down the motor stator; S3. The cutter disc rotation drive mechanism drives the cutter disc to rotate and stays at the first rotation station. The feed drive mechanism moves and drives the pushing component to move along the feed direction, so that the first type of cutter pushes and cuts the end of the flat wire. Then the feed drive mechanism returns. S4. The cutter disc rotation drive mechanism drives the cutter disc to rotate and stay at the second rotation station. The feed drive mechanism moves and drives the pushing component to move along the feed direction, so that the second type of cutter pushes and cuts the end of the flat wire. Then the feed drive mechanism returns. S5. The pressing mechanism lifts up, and the transfer mechanism sends the motor stator to the rotary cutting station; S6. The pressing mechanism presses down the motor stator, the rotary cutting drive rotates and drives the rotary cutting tool to rotate, and the rotary cutting tool contacts and cuts the flat wire end of the motor stator; S7. The pressing mechanism is lifted, and the transfer mechanism sends the processed motor stator back to the docking position.

[0013] This invention also discloses a configuration method for a universal motor stator flat wire end rotary cutting and pushing integrated machine, which is executed on the universal motor stator flat wire end rotary cutting and pushing integrated machine, including the following steps: S1. Obtain the number of slots of the stator of the motor to be processed, and construct a target slot number set containing the number of slots of each stator of the motor to be processed. The target slot number set includes at least two different motor slot numbers. S2. Based on the target slot number set, determine the circumferential equal partition N, such that the circumferential equal partition N is the greatest common factor of the target slot number in the target slot number set, and divide the circumferential direction of the motor stator into N equal processing areas accordingly; for a motor stator with M slots, the number of slots to be processed corresponding to each equal processing area is M / N, where M / N is an integer; S3. A cutting blade group is provided on the cutting blade disc of the pushing and cutting mechanism. The cutting blade group includes a first type of cutting blade and a second type of cutting blade arranged alternately in the circumferential direction. The first type of cutting blade and the second type of cutting blade are respectively inserted into the slot array of the limiting blade slot plate and move radially under the limiting of the slot array. Each of the circumferential equal partitions is provided with a first type of cutter and a second type of cutter, wherein the first type of cutter is configured to simultaneously push and cut the flat wire end corresponding to at least one slot in each equal partition processing area within one processing cycle, and the second type of cutter is configured to push and cut the remaining flat wire end corresponding to at least one slot in each equal partition processing area within one processing cycle. S4. Based on the specific target slot number M in the target slot number set of the motor stator to be processed, select a limiting cutter plate with the same number of matching slot arrays as the specific target slot number M, and control the cutter disc rotation drive mechanism to switch the cutter disc between the first rotation position and the second rotation position, and control the feed drive mechanism to drive the pushing member to push the first type of cutter and the second type of cutter in sequence within the continuous processing cycle, so as to complete the push cutting of all stator slots corresponding to the specific target slot number M.

[0014] Furthermore, the circumferential partition N is the greatest common factor of all target slots in the target slot set.

[0015] Furthermore, for a motor stator with M slots, in each equally divided processing area, the first type of cutter simultaneously cuts the flat wire ends corresponding to K1 slots in the first processing cycle, and the second type of cutter simultaneously cuts the flat wire ends corresponding to K2 slots in the second processing cycle, satisfying K1+K2=M / N.

[0016] By adopting the above technical solution, the present invention has the following beneficial effects: 1. This invention determines the number and layout of cutting blades by using the greatest common factor of the number of slots in multiple target motor stators, based on the number of slots in the stator to be processed. Combined with replaceable limiting slot plates, this achieves compatible processing of motor stators with different slot numbers using the same set of cutting blades. When switching to process motor stators with different slot numbers, only the limiting slot plates corresponding to the same number of limiting slots need to be replaced to complete the slot mapping. No disassembly or replacement of the cutting blade set is required, significantly reducing changeover costs and debugging time, and greatly improving the equipment's versatility.

[0017] 2. This invention employs a batch-cutting operation mode. The cutting disc rotation drive mechanism switches between different rotational positions, coordinating with the feed drive mechanism to sequentially push the first and second types of cutting blades with different effective cutting widths. This step-by-step processing method not only ensures full coverage cutting of all flat wire ends within the equally divided processing area, avoiding missed or incorrect cuts, but also effectively disperses the resistance of a single cut, reducing the load requirements on the drive mechanism, thereby guaranteeing the flatness and processing accuracy of the cut surface.

Detailed Implementation

[0019] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0020] Example 1: As Figure 1-7 As shown, a general-purpose motor stator flat wire end rotary cutting and pushing machine includes: Rack 1; Transfer mechanism 2 is mounted on frame 1. Transfer mechanism 2 is provided with a bearing platform 22 and a clamping part 21 mounted on the bearing platform 22. The clamping part 21 is adapted to clamp the motor stator. When the clamping part 21 moves with the bearing platform 22, it switches between the push-cutting station and the rotary cutting station to transfer the motor stator. The rotary cutting mechanism 3 is mounted on the frame 1 and is set in accordance with the rotary cutting station. The rotary cutting mechanism 3 includes a rotary cutting drive 31 and a rotary cutting cutter 32. When the rotary cutting drive 31 rotates, it drives the rotary cutting cutter 32 to rotate around the rotary cutting axis. When the motor stator is located at the rotary cutting station, the rotary cutting cutter 32 contacts the end of the flat wire of the motor stator and performs rotary cutting. The push-cutting mechanism 4 is mounted on the frame 1 and is set in accordance with the push-cutting station. The push-cutting mechanism 4 includes a cutter disc 42, a cutter group 43, a limit cutter groove plate 44, a feed drive mechanism, and a cutter disc rotation drive mechanism 48. The cutting disc 42 is rotatably mounted on the frame 1 around the central axis, and the limiting blade groove plate 44 is mounted on the cutting disc 42 and rotates synchronously with the cutting disc 42. The cutter group 43 is divided into N equal circumferential sections around the central axis. The equal circumferential sections N is the greatest common factor of the number of slots of motor stators applicable to at least two different types of motor stators with different slot numbers. The cutting blade group 43 includes a first type of cutting blade 431 and a second type of cutting blade 432. There are N first type of cutting blades 431 and N second type of cutting blades 432, which are evenly distributed in a staggered manner along the circumference, so that at least one first type of cutting blade 431 and at least one second type of cutting blade 432 are provided in each circumferentially equal partition. The limiting tool slot plate 44 is provided with a slot array 441 corresponding to the current motor stator slot being processed; the first type of cutter 431 and the second type of cutter 432 are respectively inserted into the slot array 441 and move radially under the limiting of the slot array 441. The cutting disc rotation drive mechanism 48 is mounted on the frame 1 and is connected to the cutting disc 42 in a transmission. When the cutting disc rotation drive mechanism 48 is activated, it drives the cutting disc 42, the limiting blade groove plate 44 and the cutting blade assembly 43 to rotate around the central axis and can stop at the first rotating station and the second rotating station. The feed drive mechanism is mounted on the frame 1 and is provided with a pushing member 46. The pushing member 46 is provided with a plurality of pushing parts 461 distributed in the circumferential direction. When the feed drive mechanism is activated, it drives the pushing member 46 to reciprocate along the feed direction. When the cutter disc 42 is driven to rotate to the first rotating position by the cutter disc rotation drive mechanism 48, the pushing part 461 is aligned with and abuts against the first type of cutter 431. When the pushing part 461 moves along the feed direction, it drives the first type of cutter 431 to move radially to push and cut the end of the flat wire. When the cutter disc 42 is driven to rotate to the second rotating position by the cutter disc rotation drive mechanism 48, the pressing part 461 aligns with and abuts against the second type of cutter 432. When the pressing part 461 moves along the feed direction, it drives the second type of cutter 432 to move radially to push and cut the end of the flat wire.

[0021] Specifically, such as Figure 1-7 As shown, during use, the transfer mechanism drives the clamping part to clamp the motor stator and switches between the push-cutting station and the rotary cutting station to transfer the motor stator. When the motor stator is in the rotary cutting station, the rotary cutting mechanism drives the rotary cutting tool to rotate around the rotary cutting axis through the rotary cutting drive component and contact the flat wire end of the motor stator to complete the rotary cutting. When the motor stator with 54 slots works with the cutting tool group, 18 first-class cutting tools cover the corresponding areas of two adjacent slots to complete the push-cutting, and 18 second-class cutting tools cover the corresponding area of ​​a single slot to complete the push-cutting. When the motor stator with 72 slots works with the cutting tool group, 18 first-class cutting tools cover the corresponding areas of three adjacent slots to complete the push-cutting, and 18 second-class cutting tools cover the corresponding area of ​​a single slot to complete the push-cutting. During the switching processing of the 54-slot and 72-slot motor stators, the limiting tool slot plate is replaced, but the cutting tool group is not replaced, so that the installation state of the cutting tool disc and the cutting tool group is consistent. Thus, within the same push-cutting mechanism, by switching between the first and second rotary stations, cutters with different effective cutting widths are selected to complete the push-cutting and cooperate with the rotary cutting mechanism to complete the processing of the flat wire end of the motor stator.

[0022] In this embodiment, as Figure 1-3 As shown, the general-purpose motor stator flat wire end rotary cutting and pushing integrated machine also includes a motor production conveyor line 5, which is provided with a connecting position 51; The transfer mechanism 2 includes a lifting assembly 25, a tilting mechanism 26, and a clamping mechanism 27. The lifting assembly 25 is mounted on the carrying platform 22, the tilting mechanism 26 is mounted on the lifting assembly 25, and the clamping mechanism 27 is mounted on the tilting mechanism 26. The clamping part 21 is provided on the clamping mechanism 27.

[0023] In this embodiment, as Figure 1-3As shown, the connection point 51 of the motor production conveyor line 5 is located on the side of the motor production conveyor line 5 close to the transfer mechanism 2. After the motor stator arrives at the connection point 51, the clamping mechanism 27 drives the clamping part 21 to be in an open state and aligned with the outer periphery of the motor stator. The clamping mechanism 27 moves to clamp the motor stator. The lifting component 25 moves to move the clamping mechanism 27 in the vertical direction so that the motor stator leaves the connection point 51. The carrying platform 22 moves on the frame 1 to move the lifting component 25, the flipping mechanism 26 and the clamping mechanism 27 as a whole, so that the motor stator switches between the push-cutting station and the rotary cutting station. When the flipping mechanism 26 moves, it drives the clamping mechanism 27 to rotate, so that the end face of the motor stator changes orientation, so that the end face of the motor stator meets the corresponding end face orientation requirements when entering the push-cutting station or the rotary cutting station.

[0024] Specifically, such as Figure 1-2 As shown, the universal motor stator flat wire end rotary cutting and pushing machine also includes a pressing mechanism 6. The pressing mechanism 6 is set on the bearing platform 22. The pressing mechanism 6 is equipped with a pressing head and a pressing drive component. When the pressing drive component is activated, it drives the pressing head to press down in the vertical direction and contact the upper end face of the motor stator, so as to apply a downward pressing force to the motor stator during pushing or rotary cutting.

[0025] Specifically, such as Figure 6 As shown, the limiting slot plate 44 includes two types of limiting slot plates 44 with different slot distributions. The corresponding limiting slot plates 44 are respectively set to correspond to the circumferential position of the flat wire end of the motor stator with the corresponding number of slots.

[0026] In this embodiment, as Figure 6 As shown, the limiting slot plate 44 is fixed to the cutting disc 42 by fasteners. After removing the fasteners, the limiting slot plate 44 can be removed from the cutting disc 42 and replaced with a limiting slot plate 44 with a different slot distribution. After the different limiting slot plates 44 are installed, the slot array 441 corresponds to the circumferential position of the slot at the end of the motor stator. In some embodiments, the number of limiting slot plates 44 is not limited to two types and can be set according to the type of motor stator with different number of slots.

[0027] Specifically, such as Figure 7 As shown, the effective cutting width of the first type of cutter 431 is greater than the effective cutting width of the second type of cutter 432, and the effective cutting width of the first type of cutter 431 is suitable for covering the flat wire end area corresponding to two adjacent slots, while the effective cutting width of the second type of cutter 432 is suitable for covering the flat wire end area corresponding to a single slot.

[0028] Specifically, such as Figure 1 , Figure 6 and Figure 7As shown, the general motor stator flat wire end rotary cutting and pushing integrated machine also includes an annular blade changing limit ring 47, which is fixedly installed on the frame 1 and located between the pushing member 46 and the cutting blade group 43. The annular tool changing limiting ring 47 is provided with multiple selection slots at intervals along the circumference, and the first type of cutter 431 and the second type of cutter 432 are respectively provided with matching slots corresponding to the annular tool changing limiting ring 47. The pushing member 46 is adapted to abut against the first type of cutter 431 or the second type of cutter 432 when it is located in the selection slot, thereby driving the corresponding first type of cutter 431 or the second type of cutter 432 to move radially.

[0029] Specifically, such as Figure 6-7 As shown, the pressing part 461 is also provided with a return hook, which is suitable for engaging with the mating groove hook, and drives the corresponding first type of cutter 431 or second type of cutter 432 to return radially when the pressing member 46 returns.

[0030] In this embodiment, as Figure 1 , Figure 6 and Figure 7 As shown, the annular tool changer limiting ring 47 is coaxially disposed on the outside of the cutter disc 42 and fixed to the frame 1 by a bracket, and does not rotate with the cutter disc 42. The selection groove is a notch formed on the inner circumferential surface of the annular tool changer limiting ring 47, and the width of the notch is greater than or equal to the width of the first type of cutter 431 or the second type of cutter 432. The mating groove is formed at the tail of the first type of cutter 431 and the second type of cutter 432. When the cutter disc 42 rotates, all cutters rotate with it. If a cutter is not aligned with the selection groove, the tail of the cutter is blocked by the inner wall of the annular tool changer limiting ring 47 and cannot move radially inward. When the cutter disc 42 rotates to the first rotating position, the tail of the first type of cutter 431 is exactly aligned with the selection groove of the annular tool changer limiting ring 47, and the pushing member 46 passes through the selection groove to push the first type of cutter 431.

[0031] Example 2: This example provides a method for using a universal motor stator flat wire end rotary cutting and pushing machine, including: S1. The motor stator enters through the motor production conveyor line 5 via the connection position 51. The transfer mechanism 2 clamps the motor stator and sends it to the push-cutting station. S2, Pressing mechanism 6 presses down the motor stator; S3. The cutting disc rotation drive mechanism 48 drives the cutting disc 42 to rotate and stay at the first rotation position. The feed drive mechanism is activated and drives the pushing component 46 to move along the feed direction, so that the first type of cutter 431 pushes and cuts the end of the flat wire. Then the feed drive mechanism returns. S4. The cutting disc rotation drive mechanism 48 drives the cutting disc 42 to rotate and stay at the second rotation position. The feed drive mechanism is activated and drives the pushing component 46 to move along the feed direction, so that the second type of cutter 432 pushes and cuts the end of the flat wire. Then the feed drive mechanism returns. S5. The pressing mechanism 6 lifts up, and the transfer mechanism 2 sends the motor stator to the rotary cutting station; S6, the pressing mechanism 6 presses down the motor stator, the rotary cutting drive 31 rotates and drives the rotary cutting tool 32 to rotate, the rotary cutting tool 32 contacts the end of the flat wire of the motor stator and performs rotary cutting; S7. The pressing mechanism 6 is lifted, and the transfer mechanism 2 sends the processed motor stator back to the docking position 51.

[0032] In this embodiment, as Figure 1-7As shown, after the motor stator is conveyed to the receiving position 51 via the motor production conveyor line 5, the transfer mechanism 2 moves to the receiving position 51. The clamping mechanism 27 drives the clamping part 21 to open and align with the outer periphery of the motor stator. The clamping mechanism 27 actuates to clamp the motor stator with the clamping part 21. The lifting component 25 actuates to move the motor stator away from the receiving position 51. The carrying platform 22 moves along the frame 1 to move the motor stator into the push-cutting station. After the motor stator enters the push-cutting station, the flipping mechanism 26 changes the orientation of the motor stator end face so that the end face of the motor stator faces downward. The pressing mechanism 6 drives the pressing head to contact the upper end face of the motor stator and maintain the pressing state. The cutting disc rotation drive mechanism 48 drives the cutting disc 42, the limiting cutter groove plate 44, and the cutting blade assembly 43 to rotate around the central axis and stop at the first rotating position. The feed drive mechanism drives the pressing component 46 to move along the feed direction. The pressing part 461 aligns with and abuts against the first type of cutter 431. The first type of cutter 431 moves radially and pushes and cuts the end of the flat wire of the motor stator. The feed drive mechanism returns to reset the pressing component 46 along the feed direction. Then the cutting disc... The rotary drive mechanism 48 drives the cutter disc 42, the limiting cutter groove plate 44, and the cutter assembly 43 to rotate and stop at the second rotary station. The feed drive mechanism then actuates again, driving the pressing member 46 to move along the feed direction. The pressing part 461 aligns with and abuts against the second type of cutter 432. The second type of cutter 432 moves radially and pushes and cuts the end of the flat wire of the motor stator. The feed drive mechanism returns to reset the pressing member 46 along the feed direction. After the pushing and cutting is completed, the pressing mechanism 6 lifts up, and the transfer mechanism 2 drives the motor stator to leave the pushing and cutting station and move to the rotary cutting station. After the motor stator is pressed down again by the pressing mechanism 6 and kept in the pressing state, the rotary cutting drive 31 rotates and drives the rotary cutting tool 32 to rotate around the rotary cutting axis. The transfer mechanism 2 drives the motor stator to approach the rotary cutting tool 32 until the rotary cutting tool 32 contacts the flat wire end of the motor stator and performs rotary cutting. After the rotary cutting is completed, the pressing mechanism 6 is lifted up, and the flipping mechanism 26 drives the end face of the motor stator to change its orientation again. The transfer mechanism 2 moves the processed motor stator back to the docking position 51 and releases the clamping part 21, so that the motor stator returns to the motor production conveyor line 5 to continue to be conveyed.

[0033] Example 3: This example provides a configuration method for a universal motor stator flat wire end rotary cutting and pushing integrated machine, which is executed on the universal motor stator flat wire end rotary cutting and pushing integrated machine, including the following steps: S1. Obtain the number of slots in the stator of the motor to be processed, and construct a target slot number set containing the number of slots in each stator of the motor to be processed. The target slot number set shall include at least two different motor slot numbers. S2. Determine the circumferential partition N based on the target slot number set, such that the circumferential partition N is the greatest common factor of the target slot number in the target slot number set, and divide the circumferential direction of the motor stator into N equal processing areas accordingly; for a motor stator with M slots, the number of slots to be processed corresponding to each equal processing area is M / N, where M / N is an integer; S3. A cutting blade assembly 43 is provided on the cutting blade disk 42 of the cutting mechanism 4. The cutting blade assembly 43 includes a first type of cutting blade 431 and a second type of cutting blade 432 arranged alternately in the circumferential direction. The first type of cutting blade 431 and the second type of cutting blade 432 are respectively inserted into the slot array 441 of the limiting blade slot plate 44 and move radially under the limitation of the slot array 441. One first type of cutting blade 431 and one second type of cutting blade 432 are provided in each circumferentially equal partition. The first type of cutter 431 is configured to simultaneously push and cut the flat wire end corresponding to at least one slot in each equally divided processing area within one processing cycle, and the second type of cutter 432 is configured to push and cut the remaining flat wire end corresponding to at least one slot in each equally divided processing area within one processing cycle. S4. Based on the specific target number of slots M in the target number of slots set of the motor stator to be processed, select a limiting cutter plate 44 with the same number of slot holes as the specific target number of slots M, and control the cutter disc rotation drive mechanism 48 to switch the cutter disc 42 between the first rotation position and the second rotation position, and control the feed drive mechanism to drive the pushing member 46 to push the first type of cutter 431 and the second type of cutter 432 in sequence within the continuous processing cycle, so as to complete the push cutting of all stator slots corresponding to the specific target number of slots M.

[0034] Specifically, the circumferential partition N is the greatest common factor of all target slots in the target slot set.

[0035] Specifically, such as Figure 1-7 As shown, for a motor stator with M slots, in each equally divided processing area, the first type of cutter 431 simultaneously cuts the flat wire ends corresponding to K1 slots in the first processing cycle, and the second type of cutter 432 simultaneously cuts the flat wire ends corresponding to K2 slots in the second processing cycle, and satisfies K1+K2=M / N.

[0036] In this embodiment, as Figure 1-7As shown, to perform flat wire end cutting processing compatible with at least two different slot numbers of motor stators, the circumferential equal partitions N can be determined first, based on the target slot number set to be compatible. The circumferential equal partitions N are taken as the common factor of each target slot number in the target slot number set, preferably the largest common factor, so that the circumference of the motor stator can be divided into N equal processing areas. For a motor stator with M slots to be processed, the number of slots corresponding to each equal processing area is M / N. The number of first-type cutters 431 and second-type cutters 432 in the cutter group 43 can both be set to N, and they are evenly distributed circumferentially, so that each equal processing area is equipped with at least one first-type cutter 431 and at least one second-type cutter 432. Within each equal processing area, the first-type cutter 431 simultaneously cuts the flat wire ends corresponding to K1 slots in one processing cycle, and the second-type cutter 432 cuts the flat wire ends corresponding to the remaining K2 slots, satisfying K1+K2=M / N. To reduce the number of processing cycles required to complete all slot cutting, it is preferable to use two consecutive processing cycles to complete the cutting: in the first processing cycle, the cutter disc 42 stays at the first rotary position, and the pushing part 461 pushes the first type of cutter 431 to simultaneously cut the ends of the flat lines corresponding to the K1 slots in each equally divided processing area; in the second processing cycle, the cutter disc 42 stays at the second rotary position, and the pushing part 461 pushes the second type of cutter 432 to complete the cutting of the ends of the flat lines corresponding to the K2 slots in each equally divided processing area. When switching between processing for motor stators with different slot numbers, it is only necessary to use the limiting cutter slot plate 44 with the same slot hole array 441 as the slot number for each type of slot, thereby completing the switching of the cutting processing configuration for motor stators with different slot numbers while keeping the installation layout of the cutter disc 42 and the cutter group 43 unchanged.

[0037] In one example implementation, compatibility with both 54-slot and 72-slot motor stators is required. First, a circumferential partition N is determined. The greatest common factor of 54 and 72 is 18, so N is set to 18. This divides the motor stator circumferentially into 18 equal processing zones, and 18 first-type cutters 431 and 18 second-type cutters 432 are evenly distributed circumferentially. For a 54-slot motor stator, each processing zone corresponds to 54 / 18=3 slots. K1 can be set to 2 and K2 to 1. In the first processing cycle, the 18 first-type cutters 431 simultaneously cut the flat wire ends corresponding to two adjacent slots in each processing zone. In the second processing cycle, the 18 second-type cutters 432 cut the flat wire ends corresponding to the remaining slot in each processing zone, thus completing the cutting of all 54 slots. For a 72-slot motor stator, the number of slots corresponding to each equally divided processing area is 72 / 18=4. We can take K1 as 3 and K2 as 1, so that in the first processing cycle, 18 first-type cutters 431 simultaneously push-cut the flat wire ends corresponding to the three adjacent slots in each equally divided processing area. In the second processing cycle, 18 second-type cutters 432 push-cut the flat wire ends corresponding to the remaining slot in each equally divided processing area, thus completing the pushing-cutting of all 72 slots. When switching between 54-slot and 72-slot processing, only the limiting cutter slot plate 44 is replaced. The slot hole array 441 of the 54-slot limiting cutter slot plate 44 is set according to the circumferential position of 54 slots, and the slot hole array 441 of the 72-slot limiting cutter slot plate 44 is set according to the circumferential position of 72 slots. This allows for slot number switching without changing the installation layout of the cutter group 43.

[0038] In another example implementation, compatibility with 24-slot and 36-slot motor stators is required. The greatest common factor of 24 and 36 is 12. The circumferentially divided area N is set to 12, and 12 first-type cutters 431 and 12 second-type cutters 432 are evenly distributed circumferentially. For a 24-slot motor stator, the number of slots corresponding to each equally divided processing area is 24 / 12=2. K1 can be set to 1 and K2 to 1, so that the first processing cycle completes the push-cutting of the flat wire end corresponding to one slot in each equally divided processing area, and the second processing cycle completes the push-cutting of the flat wire end corresponding to the remaining slot in each equally divided processing area, thus completing the push-cutting of all 24 slots. For a 36-slot motor stator, the number of slots corresponding to each equally divided processing area is 36 / 12=3. K1 can be set to 2 and K2 to 1, thus completing the push-cutting of all 36 slots in two processing cycles. When switching the number of slots, the slot array 441 is matched with the circumferential position of the slot by replacing the limiting slot plate 44 that matches the corresponding number of slots.

[0039] Through the above examples and implementation methods, it can be illustrated that after taking the greatest common factor of the number of slots to be compatible with the circumferentially divided N, the number of the first type of cutter 431 and the second type of cutter 432 can be fixed at N, forming N equally divided processing areas, so that the number of slots M / N in each equally divided processing area is an integer, thereby enabling the slot pushing and cutting coverage to be completed in each equally divided processing area according to the allocation relationship of K1 and K2; at the same time, by configuring the limiting slot plate 44 for different slot numbers and replacing the limiting slot plate 44 when switching processing, the slot array 441 is matched with the circumferential position of the slot of the motor stator with the corresponding number of slots, realizing the processing switching between different slot numbers without changing the installation layout of the cutter group 43, and reducing the number of processing cycles required to complete the pushing and cutting of all slots when the two-cycle method is preferably adopted.
