A stator-rotor core lamination and detection integrated device

Abstract

This invention discloses an integrated device for stacking and testing stator and rotor cores, relating to the field of motor manufacturing technology. Based on the corresponding specifications and models of the core, this solution restricts the downward pressure distance of the trigger block according to the sliding distance of the expansion seat. The trigger block, carrying the torsion sleeve, moves upward and, under the constraint of the helical groove, rotates with the sun gear, causing the protrusion to twist. The protrusion twists to a predetermined angle, creating motion interference between the upward sliding space of the corresponding number of graded stacking rings. The unobstructed graded stacking rings can then move upward, forming a pressure inner diameter of the pressurizing component that matches the outer diameter of the positioning component. This maintains the positioning and clamping of the stator while adapting to the inner diameter, achieving a perfect match for the surface during stacking. This solution not only eliminates the need to change any parts or tooling when stacking cores of different specifications, but also allows for direct placement during processing without adjustment or conversion, enabling adaptive dimensional stacking processing according to the core specifications.

Description

Technical Field

[0001] This invention relates to the field of motor manufacturing technology, and in particular to an integrated equipment for stator and rotor core stacking and testing. Background Technology

[0002] In the manufacturing process of motor stator and rotor cores, multiple layers of silicon steel sheets are typically stacked and positioned before welding and fixing to ensure the overall coaxiality, interlayer fit, and subsequent magnetic circuit performance of the core. Most existing core stacking equipment uses fixed-specification molds, where workers pre-arrange the multiple layers of steel sheets and place them inside the tooling, then use an external pressure head to press them together as a whole.

[0003] However, due to the large number of silicon steel sheets and their thinness, radial misalignment, local skewness, and misalignment of inner holes can easily occur during the actual stacking process. Such differences are disastrous in subsequent rotational welding. To avoid these problems, the tooling needs to reduce the gap between itself and the iron core to prevent misalignment. However, a smaller gap undoubtedly increases the difficulty of placement, especially after the iron core is roughly placed. It is difficult to uniformly calibrate the iron core and is highly dependent on the gap accuracy of the tooling. This can easily lead to insufficient flatness of the iron core end face after stacking.

[0004] Meanwhile, the die structure in existing lamination equipment is usually of a fixed inner diameter. Different specifications of iron cores require the replacement of corresponding die components to complete the processing. When there are multiple stator and rotor models to switch during production, the equipment needs to frequently disassemble and assemble the die, which not only increases downtime but also easily leads to uneven local clamping force due to insufficient die size matching. This results in problems such as lamination gaps, edge warping, and loose interlayers in some areas, especially for iron cores with different inner diameter specifications. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that the positioning of stator and rotor cores is easily affected by tool wear during the traditional stator and rotor core stacking and welding inspection process, and different tooling needs to be replaced for different specifications of cores. Therefore, this invention proposes an integrated equipment for stator and rotor core stacking and inspection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an integrated device for stacking and inspecting stator and rotor cores, comprising a stacking device and a welding arm mounted on a support, and a visual inspection head for inspecting the quality of stacking and welding. The stacking device further includes: The processing table, mounted on a bracket, supports the iron core and keeps it horizontal. It rotates at a fixed angle to cooperate with the welding arm for processing and lifts the iron core out after processing. The bottom of the table is equipped with a push component and a rotation driver to provide rotation or lifting for discharging. The positioning assembly includes several horizontal and axial positioning components that are radially slidably mounted on the machining table, and the horizontal and axial positioning components provide dual positioning of several sheet-like iron cores in both the axial and horizontal directions when they cooperate to expand inward. The pressurizing component is axially positioned above the positioning component and is driven to slide by hydraulic pressure. It includes a moving mold base that is adapted to fully fit and overlap the inner diameter of the positioning component under different outer diameter openings. A calibration component for adjusting the different inner diameters is installed on the moving mold base. A mold closing trigger is axially disposed through the moving mold base. The mold closing trigger includes a synchronizing rod and a torsion sleeve that slides on its surface, and a trigger block supported by a spring is fixed on the surface of the torsion sleeve. A sun gear is splined on the surface of the torsion sleeve. When the mold is closed, the synchronizing rod is inserted into the processing table to obtain direct drive from the driver. It expands within the horizontal and axial positioning parts by the extrusion block to provide dual axial and horizontal positioning for the iron core. Based on the limitation of the internal expansion amplitude, the reaction trigger block and the synchronizing rod are relatively twisted, which drives the sun gear to rotate and drive the calibration assembly to self-adapt to the inner diameter of the moving mold base.

[0007] As a further description of the above technical solution: the pressurization component includes a connector that connects the hydraulic rod and the calibration component, and the connector includes a hydraulic platform and a connecting flange fixed to its lower surface.

[0008] As a further description of the above technical solution: the calibration assembly includes a pressure plate rotatably mounted on the inner wall of the connecting flange, a plurality of adjustment structures fixed on the pressure plate, and a control structure sliding on the pressure plate to maintain the synchronization of the plurality of adjustment structures. The control structure includes a toothed ring and multiple slide rails fixed thereon, and the multiple slide rails are clamped and slid around the arc-shaped sidewall of the pressure plate. The adjustment structure includes a connecting column fixed on the pressure plate and a protrusion rotating on the connecting column, the top of which is fixed with a planetary gear that meshes with a gear ring.

[0009] As a further description of the above technical solution: the moving mold base includes an axially sliding upper mold body and a base stacking ring fixed to multiple connecting columns. The inner wall of the upper mold body is provided with an upper bracket for mounting the base stacking ring. The inner wall of the base stacking ring is slidably provided with a number of graded stacking rings that are only allowed to move upward.

[0010] As a further description of the above technical solution: the top end of the synchronizing rod of the mold closing trigger is fixed through the top of the pressure plate, the arc-shaped sidewall of the torsion sleeve is provided with a spiral groove, and the spiral groove is engaged and slidably fitted with the inner wall of the pressure plate, and the sun gear is rotatably connected to the lower surface of the pressure plate. When the mold closing trigger closes the mold downwards, the trigger block, after the horizontal positioning component and axial positioning component can no longer move, moves upwards and slides on the surface of the synchronous rod with the torsion sleeve. During the torsion, it rotates with the sun gear. The sun gear meshes with multiple planetary gears and rotates multiple protrusions at a predetermined angle, completing the upward spatial interference of the corresponding number of graded stacked rings.

[0011] As a further description of the above technical solution: the processing table includes a rotating seat fixed on the stationary mold base, and a material unloading rack installed on both the stationary mold base and the rotating seat; The static mold base includes a lower mold body and a lower bracket fixed to its inner wall for supporting the stacking platform.

[0012] As a further description of the above technical solution: the rotating seat includes a base fixed to the inner wall of the bracket, and a rotating cylinder that is rotatably mounted on the inner wall of the base and engages with the spline at the bottom of the synchronizing rod. A rotating platform is fixed to the top of the rotating cylinder, and the rotating platform is rotatably mounted on the top of the base. Several sliding grooves are provided on the upper surface of the rotating platform, and inclined pads are fixed in the sliding grooves.

[0013] As a further description of the above technical solution: the unloading rack includes a rotating slide that slides on the base, a plurality of support columns are rotatably mounted on the rotating slide, and a stacking platform is fixed to the top of the plurality of support columns. The inner wall of the stacking platform is attached to the surface of the rotating platform, and the stacking platform is flush with the upper surface of the rotating platform.

[0014] As a further description of the above technical solution: the pushing component includes a pushing rod fixed on the bracket, the end of the pushing rod is fixed with a pushing slide, the pushing slide slide slides horizontally in a guide groove opened in the inner wall of the bracket, and a pushing frame is movably connected to the pushing slide, the top of the pushing frame being movably connected to both sides of the rotating slide via a pin.

[0015] As a further description of the above technical solution: the positioning component includes several expansion seats, the bottom of the expansion seat is fixed with an inclined guide block that slides on the inner wall of the slide groove, and the horizontal positioning component and the axial positioning component both slide vertically on the expansion seat; The horizontal positioning component includes a positioning frame and two clamps that slide on the inner wall of the positioning frame. The ends of the clamps are equipped with torsion springs, and the inner wall of the positioning frame has a sliding member for pressing and deflecting the clamps.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In the mold closing process, this solution uses the synchronous rod of the mold closing trigger to cooperate with the trigger block to squeeze the expansion seat. When the axial positioning part expands, it squeezes the inner side of the iron core to align it axially. At the same time, when the horizontal positioning part moves, the sliding parts between the positioning frames are pressed and slide, and press the two clamping parts to twist and clamp the inner wall of the iron core, so that it can be aligned horizontally and neatly while being axially positioned, thus achieving autonomous horizontal and axial dual positioning after the approximate placement. 2. At the same time, the outer and inner diameters of the iron core of the corresponding specification are fixed values. The corresponding number of graded stacking rings are matched with the inner diameter of the iron core of the corresponding specification. According to the sliding distance of the expansion seat, the downward pressing distance of the trigger block is restricted in the opposite direction. The trigger block moves upward with the torsion sleeve and rotates with the sun gear under the restriction of the spiral groove, causing the protrusion to twist. The protrusion twists to a predetermined angle, forming motion interference in the upward sliding space of the corresponding number of graded stacking rings. The unblocked graded stacking rings can move upward, forming the inner diameter of the pressurizing component that is adapted to the outer diameter of the positioning component. While maintaining the positioning and clamping of the stator, it adapts to the inner diameter and fully matches and stacks on its surface.

[0017] In summary, this solution not only eliminates the need to replace any parts or tooling when stacking iron cores of different specifications, but also allows for direct placement during processing without adjustment or conversion, enabling adaptive stacking processing based on iron core specifications.

[0018] 3. This solution also uses a synchronizing rod inserted into the inner wall of the rotating cylinder and its spline to form coaxial rotation. Driven by the bottom driver, the synchronizing shaft is locked and fixed on the pressure plate, so that it rotates synchronously on the connecting flange. At the same time, the positioning component below rotates on the rotating table, and the stacking table also rotates synchronously. Based on the function of the synchronizing shaft, the iron core is clamped from above and below, and synchronous rotation can be maintained. Moreover, the rotation is not transmitted through the iron core itself. Attached Figure Description

[0021] 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.

[0022] like Figure 1 - Figure 11 As shown, the present invention provides an integrated device for stacking and inspecting stator and rotor cores, including a stacking device and a welding arm 7 mounted on a support 1, and a visual inspection head 8 for inspecting the quality of stacking and welding. The stacking device includes: The processing table 2, mounted on the bracket 1, is used to support the iron core 9 and drive it to rotate at a fixed angle while maintaining a horizontal state, so as to cooperate with the welding arm 7 to complete the processing. After the processing is completed, the iron core 9 can be lifted out of the machine. The bottom of the processing table 2 is equipped with a pushing component 5 and a rotation driver 6, which provide lifting and rotation power respectively.

[0023] Combined with appendix Figure 2 As shown, the pushing component 5 includes a pushing rod 51 fixed on the bracket 1. The end of the pushing rod 51 is fixed with a pushing slide 52. The pushing slide 52 slides horizontally in the guide groove 54 opened in the inner wall of the bracket 1. A pushing frame 53 is movably connected to the pushing slide 52. The top of the pushing frame 53 is movably connected to both sides of the rotating slide 231 through a pin.

[0024] When the push rod 51 extends or retracts, it causes the push slide 52 to move horizontally. The push slide 52 pushes the bottom of the push frame 53 to move, which in turn drives the rotary slide 231 to rise steadily along the base 211 via the pin. This lifts the stacking table 233 as a whole, thereby lifting the processed iron core 9 out of the processing area and avoiding collision deformation of the weld area during manual handling. Furthermore, the pin connection method can provide a certain angle compensation during the pushing process, ensuring that the rotary slide 231 maintains stable guidance during lifting and lowering.

[0025] Furthermore, the processing table 2 includes a rotating seat 21 fixed on the stationary mold base 22, and the stationary mold base 22 includes a lower mold body 221 and a lower bracket 222 fixed to its inner wall for supporting the stacking table 233.

[0026] The lower bracket 222 is used to bear the axial load and radial pressure generated when the stacking table 233 rotates, and to maintain the overall coaxial stability of the stacking table 233, so that it can still maintain stable rotation under high pressure stacking.

[0027] Combined with appendix Figure 3 and Figure 4As shown, the rotating seat 21 includes a base 211 fixed to the inner wall of the bracket 1. A rotating cylinder 212 that is splined to the bottom of the synchronizing rod 444 is rotatably mounted on the inner wall of the base 211. A rotating platform 213 is fixed to the top of the rotating cylinder 212. The rotating platform 213 is rotatably mounted on the top of the base 211. Several sliding grooves 214 are provided on the upper surface of the rotating platform 213, and inclined pads 215 are fixed in the sliding grooves 214.

[0028] The rotating cylinder 212 and the synchronizing rod 444 form a synchronous transmission through a spline, so that the upper pressure assembly 4 and the lower processing table 2 form a synchronous rotation state after clamping the iron core 9, thereby avoiding the transmission of rotational torque through the iron core 9 body. The inclined pad 215 inside the slide 214 is used to provide inclined guidance for the expansion seat 31. When the expansion seat 31 loses the pressure of the trigger block 442, it can be reduced and reset under the action of gravity and the inclined guide of the inclined pad 215 and the inclined guide block 34. This allows the expansion seat 31 to transform into a stable radial expansion motion after being subjected to axial pressure, and to quickly reset after losing the pressure.

[0029] The unloading rack 23 on the rotating base 21 is installed on the stationary mold base 22, so that the stationary mold base 22 and the rotating base 21 form a support and maintain the stability of the stacking.

[0030] Combined with appendix Figure 3 It is known that the unloading rack 23 includes a rotating slide 231 that slides on the base 211. Several support columns 232 are rotatably installed on the rotating slide 231. The top of the several support columns 232 is fixed together with a stacking platform 233. The inner wall of the stacking platform 233 is attached to the surface of the rotating platform 213 and is flush with the upper surface of the rotating platform 213.

[0031] The stacking table 233 is used to support the 9 layers of iron cores and maintain the overall planar support state during the stacking process. The multiple support columns 232 form a stable support when the rotating slide table 231 is raised and lowered, so that the stacking table 233 remains horizontal during the rise and prevents the iron cores 9 from tilting and slipping.

[0032] As a positioning component 3 for pre-positioning the iron core 9, refer to the attached... Figure 5 and attached Figure 6 It includes several horizontal positioning components 32 and axial positioning components 33 that are radially slidably mounted on the processing table 2. The two components can achieve dual positioning of several sheet-like iron cores 9 in the axial and horizontal directions through inward expansion. It also includes several expansion seats 31. The bottom of the expansion seat 31 is fixed with an inclined guide block 34 that slides on the inner wall of the slide groove 214. The horizontal positioning components 32 and axial positioning components 33 slide vertically on the expansion seat 31. During the downward pressing process, the expansion seat 31 expands outward along the surface of the inclined pad 215, simultaneously pushing the horizontal positioning member 32 and the axial positioning member 33 towards the inner wall of the iron core 9, thereby uniformly aligning the iron core 9 to the center. The axial positioning member 33 is used for axial alignment of the multi-layered iron core 9, while the horizontal positioning member 32 is used to correct radial misalignment between the layers. Furthermore, during the expansion sliding, a slight height difference occurs between the inclined pad 215 and the inclined guide block 34, causing the expansion seat 31 to slide within the horizontal positioning member 32 and the axial positioning member 33. This ensures that the axial and horizontal positioning members 32 and axial positioning members 33 do not interfere with each other during the outward movement of the expansion seat 31 carrying the horizontal and axial positioning members 32 and 33.

[0033] Further, see Appendix Figure 7 The horizontal positioning component 32 includes a positioning frame 321 and two clamps 322 that slide on the inner wall of the positioning frame 321. A torsion spring 324 is installed at the end of the clamp 322, and a slide 323 for pressing the clamp 322 to deflect is slidably on the inner wall of the positioning frame 321.

[0034] When pressed, the slider 323 pushes the two clamps 322 to deflect towards each other, causing the clamps 322 to be held against the inner wall of the iron core 9. The torsion spring 324 provides the clamps 322 with a restoring force, so that the horizontal positioning member 32 can automatically return to its initial state after positioning. The two clamps 322 form a symmetrical clamping structure, which keeps the iron core 9 under uniform force during positioning and reduces the risk of lamellar deformation caused by local compression.

[0035] It is used in conjunction with the above-mentioned processing table 2 for stacking processing, combined with the attached Figure 8 The pressurizing component 4 is axially positioned above the positioning component 3 and is driven to slide by hydraulic pressure. It includes a moving mold base 43 that can adapt to different outer diameter openings of the positioning component 3 to achieve full inner diameter fitting and stacking. The moving mold base 43 includes an axially sliding upper mold body 431 and a base stacking ring 432 fixed to multiple connecting columns 4221. The inner wall of the upper mold body 431 is provided with an upper bracket 434 for mounting the base stacking ring 432. The inner wall of the base stacking ring 432 is provided with several graded stacking rings 433 that can slide upwards unidirectionally. The multiple graded stacking rings 433 are matched in layers according to the specifications of the iron core 9. In an unrestricted state, they can slide upwards to avoid obstruction, while the restricted graded stacking rings 433 remain in a downward-pressed state, thereby forming effective pressing areas with different inner diameter ranges.

[0036] And refer to the appendix Figure 8 It can be seen that the multiple graded stacked rings 433 on the inner wall of the basic stacked ring 432 support each other sequentially from the outside to the inside, and under their gradient support, they can only slide upwards.

[0037] Combination Figure 10As shown, a calibration component 42 that can adjust its different inner diameters is installed on the moving mold base 43, and a mold closing trigger 44 is axially disposed through the moving mold base 43; The mold closing trigger 44 is used to trigger the positioning trigger of the positioning component 3. At the same time, it is driven between the processing table 2 and the pressure component 4 to make them rotate coaxially. It also reacts to the iron core 9 of the pressure component 4 based on the positioning state of the positioning component 3 to adapt to the specifications.

[0038] Reference Appendix Figure 9 The calibration assembly 42 includes a pressure plate 421 rotatably mounted on the inner wall of the connecting flange 412, a plurality of adjustment structures 422 fixed on the pressure plate 421, and a control structure 423 sliding on the pressure plate 421 to maintain the synchronicity of the plurality of adjustment structures 422. The control structure 423 is used to ensure that the plurality of adjustment structures 422 maintain synchronous movement during rotation adjustment, and to avoid the stacking ring from being skewed due to unilateral adjustment error.

[0039] In the above structure, the control structure 423 includes a gear ring 4231 and a plurality of slide rails 4232 fixed thereon, as shown in the attached diagram. Figure 9 Furthermore, multiple slide rails 4232 surround the arc-shaped sidewall of the pressure plate 421 to form a clamping sliding action; Furthermore, the adjustment structure 422 includes a connecting column 4221 fixed on the pressure plate 421, and a protrusion 4223 rotating on the connecting column 4221. The top of the protrusion 4223 is fixed with a planetary gear 4222 that meshes with the gear ring 4231.

[0040] When the pressure plate 421 rotates, it drives the gear ring 4231 to rotate synchronously. The gear ring 4231 drives multiple planetary gears 4222 to rotate synchronously, causing the corresponding protrusion 4223 to rotate to a predetermined angle. The protrusion 4223 then forms a spatial limit on the corresponding graded stacked ring 433, thereby controlling whether the corresponding stacked ring is allowed to move upward.

[0041] Reference Appendix Figure 8 As shown, the mold closing trigger 44, which implements the linkage between the upper and lower parts, includes a synchronizing rod 444 and a torsion sleeve 441 that slides on its surface. A trigger block 442 supported by a spring 443 is fixed on the surface of the torsion sleeve 441, and a sun gear 446 is splined on the surface of the torsion sleeve 441. Furthermore, the top end of the synchronizing rod 444 is fixed through the pressure plate 421, and the arc-shaped sidewall of the torsion sleeve 441 is provided with a spiral groove 445, which is engaged and slidably fitted with the inner wall of the pressure plate 421. The sun gear 446 is rotatably connected to the lower surface of the pressure plate 421. When the torsion sleeve 441 is twisted, it can maintain axial sliding within the sun gear 446 while rotating it.

[0042] After being squeezed in the opposite direction by the positioning component 3, the trigger block 442 pushes the torsion sleeve 441 to slide upward along the synchronizing rod 444, and forms a synchronous self-spinning action under the guidance of the spiral groove 445, so that the sun gear 446 obtains rotational driving force.

[0043] When the mold closing trigger 44 closes the mold downwards, after the trigger block 442 can no longer move due to the pressure on the horizontal positioning member 32 and the axial positioning member 33, it slides upwards along the synchronous rod 444 with the torsion sleeve 441, and rotates the sun gear 446 during the torsion. The sun gear 446 meshes with multiple planetary gears 4222, and rotates the multiple protrusions 4223 at a predetermined angle, completing the upward spatial interference of the corresponding number of graded stacked rings 433.

[0044] At this time, the graded stacking ring 433 corresponding to the target specification iron core 9 is restricted to the downward pressing position, while the graded stacking ring 433 of non-corresponding specifications slides upward to avoid it, thereby forming a pressing area that matches the inner diameter of the current iron core 9.

[0045] Furthermore, the pressurizing assembly 4 includes a connector 41 that connects the hydraulic rod to the calibration assembly 42. The connector 41 includes a hydraulic platform 411 and a connecting flange 412 fixed to its lower surface. The hydraulic platform 411 is used to withstand the axial pressure output by the hydraulic rod and to uniformly transmit the pressure to the pressure plate 421 and the moving mold base 43 through the connecting flange 412.

[0046] When the mold is closed, the synchronizing rod 444 is inserted into the processing table 2 to obtain direct drive from the driver 6, and expands within the horizontal positioning member 32 and the axial positioning member 33 by the trigger block 442 to perform axial and horizontal dual positioning of the iron core 9. Based on the limitation of the internal expansion amplitude, the reaction trigger block 442 and the synchronizing rod 444 are relatively twisted, which drives the sun gear 446 to rotate and drive the calibration component 42 to self-adapt to the inner diameter of the moving mold base 43.

[0047] Working principle: When using this solution, the iron core 9 is stacked on the stacking table 233 and kept roughly flat. Then the stacking operation can be carried out. During the stacking, the connector 41 is pushed down by the hydraulic rod. The hydraulic table 411 of the connector 41 moves down with the pressure plate 421 that can rotate below through the connecting flange 412. First, the synchronizing rod 444 passes through the shaft of multiple expansion seats 31 until it is inserted into the rotating cylinder 212 and engages with its spline. As the pressure continues to decrease, the trigger block 442 contacts multiple expansion seats 31, causing the inclined guide block 34 at the bottom of the expansion seat 31 to overcome the gravity guidance of the inclined pad block 215 in the slide groove 214 and begin to move outwards. When the expansion seat 31 moves, it pushes the horizontal positioning member 32 or the axial positioning member 33 that slides on the surface to expand. During the expansion, the axial positioning member 33 axially aligns the stacked iron core 9, while the sliding member 323 between the horizontal positioning member 32 and the positioning frame 321 is pressed and slides, and presses the two clamps 322 to twist and clamp the inner wall of the iron core 9, so that it is aligned horizontally while being axially positioned. Meanwhile, the outer and inner diameters of the corresponding specification iron core 9 are fixed values. The corresponding number of graded stacking rings 433 are matched with the inner diameters of the corresponding specification iron core 9. Based on the sliding distance of the expansion seat 31, the downward pressing distance of the trigger block 442 is restricted in the opposite direction. The trigger block 442 moves upward with the torsion sleeve 441 and rotates and twists under the restriction of the spiral groove 445 and the inner wall of the pressure plate 421. When the torsion sleeve 441 twists, it drives the planetary gear 4222 to rotate through the sun gear 446. (During this process, the gear ring 4231 slides on the side wall of the pressure plate 421 with the slide rail 4232 under the meshing of the planetary gear 4222 to further maintain the synchronicity of rotation. When the sun gear 446 is disassembled, the planetary gear 4222 can also avoid rotating alone.) (The rotation makes calibration difficult). Multiple planetary gears 4222 with protrusions 4223 rotate on the connecting post 4221. The protrusions 4223 rotate to a predetermined angle, creating motion interference in the upward sliding space of the corresponding number of graded stacking rings 433. The unobstructed graded stacking rings 433 can move upward, forming the inner diameter of the pressurizing component 4 that is adapted to the outer diameter of the positioning component 3. As the pressure continues to be applied, the base stacking ring 432 contacts the iron core 9. At the same time, the graded stacking rings 433 whose inner walls can move upward contact the positioning component 3 and slide upward. The lower surface of the graded stacking rings 433, which are squeezed by the pressure plate 421 through the connecting post 4221 and the protrusions 4223, is flush with the base stacking rings 432 and has the same pressure state to perform the stacking operation on the iron core 9. After the stacking is completed, welding arm 7 on one side is used for welding, and the drive 6 on the welding side drives the rotating cylinder 212 and the synchronous rod 444 to rotate, so that the iron core 9 rotates in the clamping between the pressure assembly 4 and the processing table 2 to perform edge welding. During the rotation, the visual inspection head 8 detects the continuity of the weld and the flatness of the stacking of the iron core 9.

[0048] After the stacking welding, the push rod 51 extends, pushing the push slide 52 to slide in the guide groove 54, and the push slide 52 supports the bottom displacement of the push frame 53, so that the push frame 53 supports the rotating slide 231 to slide upward. The rotating slide 231 pushes the stacking table 233 upward through multiple support columns 232 and separates from the rotating table 213 on the inner wall. At the same time, the stacking table 233 slides out of the lower mold body 221 and separates from the lower bracket 222, so that the iron core 9 is lifted to a height exceeding the positioning component 3.
