Description

Technical Field

[0001] This invention relates to the field of diesel generator stator processing technology, specifically to a stator stacking device and method for diesel generators. Background Technology

[0002] The stator of a diesel generator is a key component, primarily responsible for cutting the magnetic field within the rotating magnetic field generated by the rotor to produce voltage. It mainly comprises the iron core, frame, and coils. The iron core forms the main magnetic circuit of the stator and is also the component for mounting and securing the stator windings. The frame secures the iron core and bears the torque of the stator, transmitting it to the base. The coils form the generator's electrical circuit. In the generator, the stator and rotor work together, with the stator coils cutting magnetic lines of force within the rotating magnetic field to generate electrical energy.

[0003] Chinese invention patent CN118017777A discloses an intelligent stacking device and method for processing diesel generator stators, including a stacking and storage mechanism, a pressure applying mechanism, and a feeding mechanism. The feeding mechanism provides feeding stator laminations into the stacking and storage mechanism, which stacks and stores the stator laminations. The pressure applying mechanism is positioned directly above the stacking and storage mechanism to apply pressure to the stacked stator laminations. Each time a stator lamination is received, a servo motor drives the components on it to rotate by a certain angle. However, existing technologies suffer from a limited range of stator stacking methods. The stator processing stacking device cannot determine the stator's orientation during processing, leading to misalignment of the stator's core grooves and preventing complete alignment. This lack of orientation determination directly affects processing accuracy, causing deviations in the position and depth of the stator core grooves, thus impacting the overall performance of the generator. Furthermore, the need for frequent manual checks and adjustments of the stator orientation increases downtime and labor costs, reducing production efficiency.

[0004] Furthermore, the stator loading process primarily relies on manual placement, requiring users to accurately fix the stators in the work area for transport. Offset stators can easily amplify errors during movement, affecting stacking efficiency. Manual placement and fixing of stators consumes significant physical labor and time, increasing worker workload. Manual operation makes it difficult to guarantee accuracy in every placement and fixing, leading to the gradual accumulation and amplification of errors, adversely impacting the quality and performance of the final product. Over-reliance on manual operation reduces the automation level of the production line, limiting production efficiency and capacity increases.

[0005] Therefore, it is necessary to design and create a stacking device and method for processing diesel generator stators. Summary of the Invention

[0006] The purpose of this invention is to overcome the problems in the prior art where the iron core grooves are not easy to align, affecting the processing accuracy, and where manual operation is difficult to guarantee accuracy, thus limiting the improvement of production efficiency and capacity. The invention provides a stator stacking device and method for diesel generators, which has the advantages of improving the alignment accuracy while improving the stacking automation effect.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a stator stacking device for a diesel generator, comprising a mounting base, a feeding component fixedly disposed on the mounting base for stacking iron cores to be stacked, and a base disposed on the mounting base and adapted to the inner ring of the iron core so that the iron core can be aligned and fitted into the mounting, characterized in that it further comprises:

[0008] The transport assembly is used to transfer the stacked iron core segments to the top of the machine base.

[0009] The fixing component, which is linked with the transport component, has a swing arm for clamping the iron core to be stacked and a limiting block provided on the swing arm and cooperating with the groove on the outer surface of the iron core to be stacked;

[0010] The adjustment component, linked to the transport component, has an adjustment ring for rotating the iron core to be stacked during transport so that the limiting block is engaged in the groove to complete the rotation angle positioning of the iron core to be stacked.

[0011] The press-fit assembly is used to fit the iron core to be stacked into the machine base.

[0012] This invention, through integrated design, automates the process of stacking, aligning with, fixing, lifting, and mounting the iron core to the machine base, greatly improving production efficiency, reducing manual operation, lowering labor intensity, and simultaneously improving processing accuracy and product quality.

[0013] Furthermore, the transport assembly includes a support plate for carrying the iron cores to be stacked, a drive component fixedly disposed between the mounting base and the support plate for driving the support plate to move, and a pusher frame fixedly disposed above the support plate for pushing out the bottom layer of the iron cores to be stacked in the loading assembly. The pusher frame also has a support surface that supports the remaining iron cores to be stacked in the loading assembly after pushing out the bottom layer of the iron cores to be stacked, thereby completing the segmented transport. This invention utilizes the driving force of the drive component, as well as the synergistic effect of the support plate and the pusher frame, to achieve precise pushing of the iron cores from the stacked state to the top of the machine base. This not only improves the transport efficiency of the iron cores but also ensures the stability and accuracy of the iron cores during movement.

[0014] Furthermore, the fixing assembly also includes shrink-fit plates fixedly disposed on both sides of the mounting base and extending inwardly at one end near the machine base. The swing arm of the fixing assembly is rotatably disposed on both sides of the bearing plate, and the limiting block is disposed on the inner side of the swing arm. The outer side of the swing arm is slidably connected to the inner side of the shrink-fit plate, giving the swing arm a clamping tendency. This invention, through the cooperation of the shrink-fit plate and the swing arm, and the insertion action of the limiting block, effectively prevents the core from shifting during transportation, ensures the alignment accuracy between the core and the machine base, improves the stability and reliability of the stacking process, and reduces processing errors caused by core displacement.

[0015] Furthermore, the adjusting ring is rotatably disposed inside the pushing frame, and the adjusting assembly also has a linkage structure that drives the adjusting ring to rotate during the movement of the transport assembly. The linkage structure includes a toothed plate fixedly disposed inside the shrink plate, a gear disposed on the top of the bearing plate and meshing with the toothed plate, and a synchronous transmission component disposed between the gear and the adjusting ring. The synchronous transmission component includes pulleys fixedly disposed on the top of the gear and the top of the adjusting ring, and a belt sleeved on the surface of the pulley. This invention, through the rotational function of the adjusting ring, allows the iron core to adjust its rotation angle during pushing, ensuring that the surface groove corresponds to the limiting block. This not only simplifies the operation process but also improves the assembly accuracy of the iron core and the machine base, ensuring the consistency of the stacking effect.

[0016] Furthermore, the pressing assembly includes a clamping part disposed above the machine base for clamping the aligned iron core and a lifting part disposed above the clamping part for driving the iron core to move vertically up and down and fitting the iron core into the machine base.

[0017] Furthermore, the clamping part includes a cylinder fixedly connected to the output end of the lifting part. A jaw is fixedly hinged to the bottom of the cylinder, surrounding the output end of the cylinder. The jaw adapts to a groove inside the iron core to be stacked. A conical block located inside the jaw is fixedly connected to the output end of the cylinder. When the cylinder drives the conical block to rise, the conical block can squeeze the jaw, causing it to open outwards around the hinge point as an axis, thereby pressing against the groove inside the iron core to be stacked and completing the clamping. This invention, through the cooperation of the cylinder, jaw, and conical block, achieves reliable clamping and pressurized connection of the iron core, improves the connection strength between the iron core and the jaw, and ensures the stability of the iron core during lifting and stacking processes.

[0018] Furthermore, the lifting unit includes an electric telescopic rod vertically slidably mounted on the mounting base and fixedly connected to the top of the cylinder, extrusion plates disposed on both sides of the top of the support plate, and force-bearing rods fixedly disposed on both sides of the surface of the electric telescopic rod. The side of the extrusion plate away from the support plate is inclined for sliding contact with the force-bearing rods. When the support plate drives the extrusion plate to move horizontally, the extrusion plate can drive the electric telescopic rod and the clamping part to move up and down through the force-bearing rods. This invention utilizes the extrusion force during horizontal movement to drive the electric telescopic rod to slide vertically, improving the compactness and integration of the equipment.

[0019] A method for stacking stators for diesel generators, the method being implemented based on the stacking apparatus for diesel generator stator processing as described above, includes the following steps:

[0020] Initial preparation stage: The iron cores 2 to be stacked are stacked in the loading component 10 of the mounting base 1, and the transport component 4 is in the initial position, waiting to be started;

[0021] Iron core pushing and fixing: The drive unit 12 is started, pushing the support plate 13 and the push frame 14 to move horizontally. The push frame 14 pushes the bottom iron core 2 of the loading component 10 to the outside of the loading component 10. The shrink plate 15 in the fixing component 5 cooperates with the swing rod 16 to insert the limiting block 17 into the iron core 2 and fix the iron core 2.

[0022] Core alignment and rotation: The push frame 14 continues to move horizontally, pushing the removed core 2 to the top of the base 3 to achieve initial alignment between the core 2 and the base 3. During this process, the adjustment component 20 starts to work, and the synchronous transmission component drives the adjustment ring 19 to rotate. The rotation of the adjustment ring 19 pushes the core 2 to rotate synchronously, so that the limit block 17 is inserted into the groove of the core 2 to complete the rotation angle positioning of the core 2.

[0023] Iron core clamping and lifting: After the iron core 2 is pushed to the top of the machine base 3 and rotated to align, the extrusion plate 29 presses the electric telescopic rod of the lifting part 28 through the force rod 30, causing the electric telescopic rod to slide vertically upward. The output end of the electric telescopic rod carries the clamping part 7 down and clamps the iron core 2. Subsequently, the electric telescopic rod starts, driving the clamping part 7 and the iron core 2 to rise vertically, so that the iron core 2 is disengaged from the bearing plate 13.

[0024] Core Installation and Reset: When the support plate 13 is reset by the retraction force of the drive member 12, the drive member 12 drives the support plate 13 and the push frame 14 back to the initial position, preparing for the next core 2 push. At the same time, the pressing plate 29 on the surface of the support plate 13 disengages from the electric telescopic rod. The electric telescopic rod, which has lost pressure, uses the clamping part 7 to carry the core 2 vertically down and precisely install the core 2 on the surface of the base 3.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. This invention, through the coordinated arrangement of transport, fixing, and adjusting components, ensures that the iron core to be stacked is simultaneously adjusted in rotation angle and clamped in position during transport, guaranteeing the accuracy of subsequent pressing. Specifically, the cooperation of the shrink plate and swing rod, along with the insertion of the limiting block, effectively prevents displacement of the iron core during transport, reducing processing errors caused by core displacement. Furthermore, the rotation function of the adjusting ring allows the iron core to automatically adjust its direction during pushing, ensuring that its surface grooves correspond to the limiting block, guaranteeing consistent stacking results. Compared to existing stacking devices that struggle to guarantee alignment accuracy, this invention offers high assembly precision and reliability, improving product processing accuracy and quality.

[0027] 2. This invention improves the automation level and operating efficiency of the equipment by linking the transport component, the fixing component and the adjusting component, the clamping part and the lifting part, and the translational movement of the transport component and the lifting movement of the lifting part. At the same time, it ensures the compactness and integration of the equipment. Compared with the prior art, which requires manual operation in some processes, this invention simplifies the operation process, reduces manual operation, and improves production efficiency.

[0028] 3. This invention achieves reliable clamping and pressurized connection of the iron core through the cooperation of cylinder, chuck, and conical block, which improves the connection strength between the iron core and the chuck, ensures the stability and reliability of the iron core during lifting and setting, and avoids wear caused by friction between the iron core and the machine base during setting, thus affecting the processing accuracy and quality of the product.

[0038] 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.

[0039] Please refer to Figures 1 to 8 As shown, the present invention provides a stator stacking device and method for a diesel generator, comprising a mounting base 1, a feeding component 10 fixedly disposed on the mounting base 1 for stacking iron cores 2 to be stacked, and a base 3 disposed on the mounting base 1 and adapted to the inner ring of the iron cores 2 so that the iron cores 2 can be aligned and fitted into the mounting base. It also includes: a transport component 4 for transporting the iron cores 2 to be stacked in sections to the top of the base 3; a fixing component 5, linked to the transport component 4, having a swing arm 16 for clamping the iron cores 2 to be stacked and a limiting block 17 disposed on the swing arm 16 and cooperating with a groove on the outer surface of the iron cores 2 to be stacked; an adjusting component 20, linked to the transport component 4, having an adjusting ring 19 for rotating the iron cores 2 to be stacked during transport so that the limiting block 17 engages with the groove to complete the rotation angle positioning of the iron cores 2 to be stacked; and a pressing component 6 for fitting the iron cores 2 to be stacked into the base 3.

[0040] Please refer to Figure 3 As shown, the mounting base 1 includes a connecting frame 8 located at the bottom of the base 3. Columns 9 are provided on both sides of the top of the connecting frame 8. A feeding component 10 is fixedly connected to the inner side of each column 9. The feeding component 10 is a vertically continuous feeding pipe. Iron cores 2 are stacked inside the feeding component 10 and slidably connected to it. A transport component 4 is fixedly connected to the inner side of the column 9 and located at the bottom of the feeding component 10. During horizontal movement, the transport component 4 can carry the bottommost iron core 2 of the feeding component 10 and move it horizontally synchronously.

[0041] As a technical optimization of the present invention, the stable structure of the connecting frame 8 and the column 9 provides a stable support platform for the entire stacking process. The design of the feeding component 10 enables the iron core 2 to be stacked in an orderly manner and facilitates the horizontal movement of the transport component 4, ensuring the stability and continuity of the iron core 2 during the movement process.

[0042] Please refer to Figure 3 As shown, the transport assembly 4 includes a support plate 13 for carrying the iron cores 2 to be stacked, a drive component 12 fixedly disposed between the mounting base 1 and the support plate 13 for driving the support plate 13 to move, and a push frame 14 fixedly disposed above the support plate 13 for pushing out the bottom layer of the iron cores 2 to be stacked in the loading component 10. The push frame 14 also has a support surface that supports the remaining iron cores 2 to be stacked in the loading component 10 after pushing out the bottom layer of the iron cores 2 to be stacked in the loading component 10, thereby completing the segmented transfer. The drive component 12 is a hydraulic cylinder. The transport assembly 4 also includes a frame 11 fixedly connected to the surface of the column 9. Drive components 12 are provided on both sides of the bottom of the loading frame. The output end of the drive component 12 is fixedly connected to the inner surface of the frame 11. The support plate 13 is fixedly connected to the top of the drive component 12. The push frame 14 is fixedly connected to the top of the support plate 13. The push frame 14 can push the iron cores 2 between the support plate 13 and the loading component 10 to the top of the machine base 3 during horizontal movement. A baffle plate is fixedly connected to the top of the push frame 14. The baffle plate can seal the bottom of the feeder 10 when the push frame 14 is out of contact with the feeder 10, and can control the falling state of the iron core 2.

[0043] As a technical optimization of the present invention, by utilizing the driving force of the driving component 12 and the synergistic effect of the bearing plate 13 and the pushing frame 14, the iron core 2 is accurately pushed from the stacked state to the top of the base 3, which not only improves the conveying efficiency of the iron core 2, but also ensures the stability and accuracy of the iron core 2 during the movement.

[0044] Please refer to Figure 4 As shown, the fixing assembly 5 includes a shrink plate 15 fixedly connected to the inner side of the column 9. The side of the shrink plate 15 away from the column 9 is configured to extend inward at an angle. Both sides of the top of the bearing plate 13 are movably connected to a swing rod 16 via pins. The outer side of the swing rod 16 is slidably connected to the inner side of the shrink plate 15. A limit block 17 is fixedly connected to the inner side of the swing rod 16. The side of the limit block 17 away from the swing rod 16 extends into the interior of the iron core 2 and interlocks with the iron core 2. A roller is movably connected to the outer side of the swing rod 16 via a pin. The outer surface of the roller contacts the inner side of the shrink plate 15, and the roller is slidably connected to the shrink plate 15. The roller reduces frictional loss generated during the sliding of the swing rod 16.

[0045] As a technical optimization of the present invention, the cooperation of the shrink plate 15 and the swing rod 16, as well as the insertion of the limiting block 17, effectively prevents the iron core 2 from shifting during transportation, ensures the alignment accuracy between the iron core 2 and the machine base 3, improves the stability and reliability of the stacking process, and reduces the processing error caused by the displacement of the iron core 2.

[0046] Please refer to Figure 4 As shown, the surface of the push frame 14 is set to a hollow state, and a movable block 18 is fixedly connected to the surface of the push frame 14. An adjusting ring 19 located inside the push frame 14 is movably connected to the surface of the movable block 18 through a bearing. The shape of the outer surface of the adjusting ring 19 corresponds to the groove on the surface of the iron core 2.

[0047] As a technical optimization of the present invention, the hollow design of the push frame 14 and the rotation function of the adjustment ring 19 enable the iron core 2 to rotate and position itself during the push process, so that the groove on its surface corresponds to the limiting block 17. This not only simplifies the operation process, but also improves the assembly accuracy of the iron core 2 and the base 3, ensuring the consistency of the stacking effect.

[0048] Please refer to Figure 8 As shown, the adjusting assembly 20 also has a linkage structure that drives the adjusting ring 19 to rotate during the movement of the transport assembly 4. The linkage structure includes a bracket 21 fixedly connected to the top of the support plate 13. A gear 22 is movably connected to the surface of the bracket 21 via a bearing. A toothed plate 23 located on one side of the gear 22 is fixedly connected to one side of the shrink plate 15. The toothed plate 23 meshes with the gear 22. A synchronous transmission component is provided between the gear 22 and the adjusting ring 19. The synchronous transmission component includes a pulley 24 fixedly connected to the top of the gear 22 and the top of the adjusting ring 19, and a belt 25 sleeved on the surface of the pulley 24. During the movement of the support plate 13 carrying the adjusting ring 19, the gear 22 meshes with the toothed plate 23 and uses thrust to drive the adjusting ring 19 to rotate through the pulley 24 and the belt 25. During the rotation of the adjusting ring 19, it can drive the iron core 2 to rotate synchronously and make its surface groove correspond to the limiting block 17.

[0049] As a technical optimization of the present invention, the automatic rotation of the adjusting ring 19 during the movement of the bearing plate 13 is realized through the cooperation of gear 22, toothed plate 23, pulley 24 and belt 25. This fully utilizes the principle of mechanical transmission, realizes the effective transfer and conversion of energy, and improves the automation level and operating efficiency of the equipment.

[0050] Please refer to Figure 5As shown, the pressing assembly 6 includes a clamping part 7 disposed above the base 3 for clamping the aligned iron core 2, and a lifting part 28 disposed above the clamping part 7 for driving the iron core 2 to move vertically and fitting the iron core 2 into the base 3. The lifting part 28 includes guide rods 26 fixedly connected to both sides of the top of the connecting frame 8. The side of the guide rods 26 away from the connecting frame 8 extends to the top of the support plate 13. A connecting plate 27 is sleeved on the surface of the guide rods 26. An electric telescopic rod of the lifting part 28 is fixedly connected to the inner side of the connecting plate 27. The clamping part 7 is fixedly connected to the surface of the output end of the electric telescopic rod. The electric telescopic rod can use the clamping part 7 to clamp and connect the iron core 2 pushed to the top of the base 3 and carry it to move vertically. The lifting unit 28 also includes pressing plates 29 fixedly connected to both sides of the top of the support plate 13. The side of the pressing plate 29 away from the support plate 13 is set in an inclined shape. Both sides of the surface of the electric telescopic rod are fixedly connected to force rods 30. The side of the force rod 30 away from the electric telescopic rod contacts the pressing plate 29 and can slide on the surface of the pressing plate 29. When the support plate 13 carries the pressing plate 29 horizontally, the pressing plate 29 can use the force rods 30 to press the electric telescopic rod so that it slides vertically on the surface of the guide rod 26 through the connecting plate 27.

[0051] As a technical optimization of the present invention, the vertical lifting and mounting of the iron core 2 is achieved through the coordinated action of the guide rod 26, the connecting plate 27, the electric telescopic rod, and the clamping part 7. This not only improves the handling efficiency of the iron core 2 but also ensures the stability and safety of the iron core 2 during the lifting process. Furthermore, by utilizing the compressive force during the horizontal movement of the transport component 4 to drive the electric telescopic rod to slide vertically, the drive mechanism of the pressing component 6 is simplified, and the compactness and integration of the equipment are improved.

[0052] Please refer to Figure 5 As shown, the clamping part 7 includes a cylinder 31 fixedly connected to the output end of the electric telescopic rod. A support block 32 is fixedly connected to the bottom of the cylinder 31 and surrounds the outer side of the output end. A pawl 33 is movably connected to the surface of the support block 32 via a pin. The side of the pawl 33 away from the support block 32 extends into the interior of the iron core 2. A conical block 34 located inside the pawl 33 is fixedly connected to the output end of the cylinder 31. The outer surface of the conical block 34 contacts the inner side of the pawl 33. When the cylinder 31 drives the conical block 34 to rise, the conical block 34 can squeeze the pawl 33, causing it to swing outward around the pin. When the outer sides of multiple pawls 33 are in contact with the iron core 2, a pressurized connection between the iron core 2 and the pawls 33 can be completed.

[0053] As a technical optimization of the present invention, the cylinder 31, support block 32, chuck 33 and conical block 34 cooperate to achieve reliable clamping and pressurized connection of iron core 2, improve the connection strength between iron core 2 and chuck 33, and ensure the stability of iron core 2 during lifting and sleeve installation.

[0054] Please refer to Figure 6 As shown, a limiting rod 35 is fixedly connected inside the connecting frame 8. A base plate 36 is sleeved on the surface of the limiting rod 35. A limiting ring 37 located inside the base 3 is fixedly connected to the top of the base plate 36. The limiting ring 37 is inserted into the base 3. A shift fork 38 is movably connected to the outside of the column 9 through a pin. A crank 39 is movably connected to the bottom end of the shift fork 38 through a pin. The side of the crank 39 away from the shift fork 38 is movably connected to the top of the base plate 36 through a pin. A transmission rod 40 is fixedly connected to the surface of the driving component 12. The side of the transmission rod 40 away from the driving component 12 can move into the interior of the shift fork 38 during the movement of the driving component 12 and push the shift fork 38 to swing.

[0055] As a technical optimization of the present invention, the design of the base plate 36 and the limiting ring 37 provides reliable support and limiting for the stacking and positioning of the iron core 2. At the same time, the cooperation of the shift fork 38, the crank 39 and the transmission rod 40 realizes the automatic swing of the base plate 36, which further improves the automation level and ease of operation of the equipment, not only improving production efficiency, but also reducing the difficulty of operation and labor intensity.

[0056] Please refer to Figure 1 As shown, this embodiment also provides a method for stator stacking of a diesel generator, including the following steps:

[0057] Initial preparation stage: The iron core 2 is randomly stacked inside the loading part 10 of the mounting base 1 and is slidably connected with the loading part 10 to ensure that the iron core 2 can slide out smoothly. The machine base 3 is located at the bottom of the mounting base 1 and is fitted on the surface of the limiting ring 37 to ensure the stability of the machine base 3 during the processing. The transport component 4 and the fixing component 5 are both in the initial position and waiting to be started.

[0058] Pushing and fixing the iron core 2: The drive unit 12 is activated, pushing the support plate 13 and the push frame 14 to move horizontally. The push frame 14 first contacts the bottom iron core 2 of the loading component 10 and pushes it to the outside of the loading component 10. The support plate 13 supports the removed iron core 2, and the support surface at the rear of the push frame 14 simultaneously supports the remaining iron core 2 in the loading component 10. The shrink plate 15 in the fixing assembly 5 cooperates with the swing rod 16 to insert the limiting block 17 into the iron core 2, fixing the iron core 2 and preventing it from shifting in the subsequent process.

[0059] Core 2 Alignment and Rotation: The pusher frame 14 continues to move horizontally, pushing the removed core 2 to the top of the base 3, achieving initial alignment between the core 2 and the base 3. During this process, the adjustment component 20 starts to work, the gear 22 moves with the bearing plate 13 and meshes with the toothed plate 23, and drives the adjustment ring 19 to rotate through the belt 25 and pulley 24. The shape of the outer surface of the adjustment ring 19 corresponds to the groove on the surface of the core 2, pushing the core 2 to rotate synchronously, ensuring that the groove of the core 2 completely corresponds to the limit block 17, further strengthening the fixation and positioning of the core 2.

[0060] Iron core 2 clamping and lifting: After the iron core 2 is fully pushed to the top of the base 3 and rotated to align, the pressing plate 29 on the top of the bearing plate 13 presses the electric telescopic rod through the force rod 30, causing it to slide vertically upward on the surface of the guide rod 26 through the connecting plate 27. The output end of the electric telescopic rod carries the clamping part 7 down and clamps the iron core 2. The cylinder 31 drives the conical block 34 to rise, pressing the claws 33 to open outward. The outer sides of the multiple claws 33 contact the iron core 2, completing the pressurized connection between the iron core 2 and the claws 33. Subsequently, the electric telescopic rod starts, driving the clamping part 7 and the iron core 2 to rise vertically, causing the iron core 2 to disengage from the bearing plate 13.

[0061] Core 2 installation and reset: When the bearing plate 13 is reset by the retraction force of the drive member 12, the drive member 12 drives the bearing plate 13 and the push frame 14 back to the initial position, ready for the next core 2 push. At the same time, the pressing plate 29 on the surface of the bearing plate 13 disengages from the electric telescopic rod. The electric telescopic rod, which loses pressure, carries the core 2 through the guide rod 26 and descends vertically using the clamping part 7, and accurately installs the core 2 on the surface of the base 3.

[0062] The working principle and specific application of this invention are as follows: During the stacking process of the diesel generator stator, without distinguishing the placement angle of the iron core 2, the iron filings are directly stacked inside the loading part 10 of the mounting base 1 and slidably connected to the loading part 10. The base 3 is located at the bottom of the mounting base 1 and is sleeved on the surface of the limiting ring 37. The transport component 4 (including the frame 11, drive component 12, bearing plate 13 and push frame 14) and the fixing component 5 (including the shrink plate 15, swing rod 16 and limiting block 17) are all in the initial position. When processing is required, the drive component 12 is activated, and the drive component 12 pushes the bearing plate 13 and push frame 14 to move horizontally. During this process, the push frame 14 first contacts the bottom iron core 2 of the loading part 10 and pushes it to the outside of the loading part 10. At the same time, the shrink plate 15 in the fixing component 5 cooperates with the swing rod 16, so that the limiting block 17 is inserted into the iron core 2, fixing the iron core 2 and preventing its displacement. The pusher frame 14 horizontally pushes the lowest iron core 2 between the support plate 13 and the feed piece 10 to the top of the base 3, achieving initial alignment between the iron core 2 and the base 3.

[0063] During the movement of the push frame 14, the adjusting component 20 starts to work. The gear 22 moves with the support plate 13 and meshes with the toothed plate 23, driving the adjusting ring 19 to rotate via the belt 25 and pulley 24. The shape of the outer surface of the adjusting ring 19 corresponds to the groove on the surface of the iron core 2, so it can push the iron core 2 to rotate synchronously during horizontal movement, ensuring that the groove of the iron core 2 is completely aligned with the limiting block 17, further reinforcing the fixation and positioning of the iron core 2.

[0064] After the iron core 2 is fully pushed to the top of the base 3 and rotated to align, the pressing plate 29 on the top of the bearing plate 13 plays an auxiliary role. The pressing plate 29 is set in an inclined position. When the bearing plate 13 carries the pressing plate 29 to move horizontally, the pressing plate 29 presses the electric telescopic rod through the force rod 30, so that it slides vertically upward on the surface of the guide rod 26 through the connecting plate 27. When the bearing plate 13 carries the iron core 2 to the bottom of the clamping part 7, the output end of the electric telescopic rod carries the clamping part 7 (including cylinder 31, support block 32 and chuck 33) down and clamps the iron core 2. When the chuck 33 at the bottom of the cylinder 31 moves into the interior of the iron core 2, the cylinder 31 drives the conical block 34 to rise, pressing the chuck 33 to make it open outward. The outer sides of the multiple chucks 33 contact the iron core 2, completing the pressurized connection between the iron core 2 and the chuck 33. Subsequently, the electric telescopic rod is activated, causing the clamping part 7 and the iron core 2 to rise vertically, disengaging the iron core 2 from the support plate 13. When the two are separated and the support plate 13 is reset by the retraction force of the drive member 12, the drive member 12 drives the support plate 13 and the push frame 14 back to the initial position, ready for the next push of the iron core 2. At the same time, the pressing plate 29 on the surface of the support plate 13 disengages from the electric telescopic rod, causing the electric telescopic rod, which has lost pressure, to descend vertically through the guide rod 26 with the iron core 2 carried by the clamping part 7, and precisely place the iron core 2 onto the surface of the base 3. When the push plate on the top of the support plate 13 moves to the other side of the loading part 10, the next layer of iron core 2 in the loading part 10 slides down to the position of the push frame 14 under the action of gravity, waiting for the next push and stacking. This cycle repeats until all the iron core 2 are stacked.

[0065] To ensure smooth processing, the connecting frame 8 is equipped with a limiting rod 35 and a base plate 36. The top of the base plate 36 has a limiting ring 37 that is inserted into the machine base 3, providing additional positioning support and preventing the machine base 3 from tilting or tipping over. Meanwhile, the shift fork 38 and crank 39 mechanism on the outside of the column 9 cooperate with the transmission rod 40 of the drive component 12. When the drive component 12 moves, the transmission rod 40 pushes the shift fork 38 to swing, and the crank 39 drives the base plate 36 to adjust its position, so that the base plate 36 can carry the machine base 3 to the outside of the connecting frame 8, making it convenient for the user to replace the machine base 3.

[0066] In summary, the stacking device and method for diesel generator stator processing, through integrated design, realizes the automated process of stacking the iron core 2 to aligning, fixing, lifting and setting it with the base 3, which greatly improves production efficiency, reduces manual operation, reduces labor intensity, and improves processing accuracy and product quality.
