Description

Technical Field

[0001] This application relates to the field of transformer core conveying technology, and in particular to a transformer core fastening and turning device. Background Technology

[0002] The iron core is one of the core components of a transformer. It is mainly composed of a large number of stacked silicon steel sheets and is shaped like a rectangle. The main function of the iron core is to increase the magnetic induction intensity of the transformer and reduce magnetic circuit losses, thereby realizing the transmission and conversion of energy. The iron cores are usually stacked horizontally. After stacking, they are fixed with an iron core frame. Then, the entire iron core frame needs to be flipped by a flipping device before it can be transported and processed in the next step.

[0003] Chinese Patent CN103964172A discloses an automatic core turning table, including an input roller mechanism, an output roller mechanism, a turning table, and a turning table base. The turning table base provides rolling support for the turning table via support shaft assemblies at the front and rear ends. A turning motor is fixed on one side of the turning table base, and the output end of the turning motor is connected to a turning gear assembly via a turning transmission chain. The turning gear assembly meshes with a turning table chain located at the bottom of the turning table. An output roller mechanism is fixed on the left side of the turning table, and an input roller transverse track is fixed on the right side of the turning table. An input roller mechanism is mounted on the input roller transverse track. During operation, the core laminations are transported to a suitable position via the input roller mechanism. The transverse motor then drives the input roller mechanism to move laterally along the transverse track, causing the core lamination fixture on the input roller mechanism to press against the output roller mechanism. Subsequently, the turning motor starts, and the turning table is driven to rotate 90° through the cooperation of the turning transmission chain and the turning gear assembly. The core lamination fixture rotates with the turning table and enters the output roller mechanism. Finally, the output roller mechanism transports the rotated core laminations to the next processing step, thereby realizing the automatic turning of the core.

[0004] However, in the aforementioned prior art, after the flipping device completes one flipping operation, the flipping table is in a 90° flipped state. At this time, the positions of the input roller mechanism and the output roller mechanism also shift with the flipping table, making it impossible to directly receive the next iron core to be flipped. In order to achieve continuous operation, the flipping motor must be controlled to rotate 90° in the opposite direction to drive the flipping table to reset, so that the input roller mechanism and the output roller mechanism return to their initial working positions before the next iron core flipping operation can be carried out. This flipping-reset-flipping operation mode increases the ineffective action time of the equipment, resulting in a decrease in iron core flipping efficiency, which has obvious shortcomings. Summary of the Invention

[0005] To improve the core flipping efficiency, this application provides a transformer core fastening and flipping device.

[0006] The transformer core fastening and flipping device provided in this application adopts the following technical solution: A transformer core fastening and flipping device includes a frame with a loading station and a unloading station at opposite ends. A flipping groove is provided between the loading station and the unloading station on the frame. A flipping shaft is rotatably connected between the opposite sidewalls of the flipping groove. Four bearing plates are fixed on the outer surface of the flipping shaft. The four bearing plates are evenly distributed along the circumference of the flipping shaft. A flipping station is formed between the opposite surfaces of two adjacent bearing plates in the circumferential direction. A fixing component and a transfer component are provided on the surface of one of the bearing plates at the flipping station. The fixing component is used to fix the core frame on the bearing plate. The transfer component moves the core frame to the side of the flipping groove closer to the unloading station. A loading component is provided at the loading station to transfer the core frame to the bearing plate closer to the loading station. A flipping component is provided on the frame to drive the flipping shaft to rotate.

[0007] By adopting the above technical solution, the iron core frame is sequentially transferred to the loading station of the frame. The loading component transfers the iron core frame to the fixing component on the bearing plate. Then, the fixing component clamps and fixes the iron core frame. After fixing, the flipping component drives the flipping shaft to rotate. The rotation of the flipping shaft causes the four bearing plates to rotate synchronously by 90°. At this time, the bearing plate carrying the iron core frame rotates to the unloading station, and the iron core frame changes from a horizontal to a vertical state. The transfer component moves the flipped iron core frame to the side closer to the unloading station, and the fixing component releases its clamping on the iron core frame. The unloading device at the unloading station unloads the vertical iron core frame, thus realizing the flipping operation of one iron core frame. Then, the loading component transfers the next iron core frame to be flipped to the empty support plate near the loading station. The above flipping process is repeated. During the flipping of the next iron core frame, the fixing component and transfer component at the previous flipping station are reset to support the subsequent iron core frame. In this way, the continuous flipping operation of the iron core frame is realized without waiting for the previous flipping station to reset, shortening the single iron core flipping cycle and thus improving the iron core flipping efficiency.

[0008] Optionally, the flipping assembly includes a flipping motor mounted on the frame, the output shaft of the flipping motor being connected to a drive gear via a reduction gearbox, and a driven gear coaxially fixed at the end of the flipping shaft, meshing with the drive gear.

[0009] By adopting the above technical solution, the output shaft power of the flipping motor is transmitted to the drive gear after being reduced and increased in torque by the reduction gearbox. The drive gear drives the meshing driven gear to rotate, and the driven gear drives the flipping shaft to rotate, thereby realizing the synchronous rotation of the four bearing plates. The reduction gearbox can effectively protect the flipping motor and reduce the load on the flipping motor, thereby improving the stability and service life of the flipping assembly.

[0010] Optionally, each of the bearing plates is provided with a mounting shaft at the end away from the flipping shaft, and guide wheels are rotatably connected to both sides of the mounting shaft along its axial direction. Guide frames that roll in cooperation with the guide wheels are provided on the inner wall of the flipping groove and on the frame.

[0011] By adopting the above technical solution, during the rotation of the flipping shaft, the guide wheel on the mounting shaft rolls along the guide frame, thereby reducing the friction when the bearing plate rotates, ensuring that the rotation process of the bearing plate is more stable, and reducing the possibility of the bearing plate shaking and shifting due to uneven force.

[0012] Optionally, the transfer component is a transfer guide rail disposed on the support plate, and the fixing assembly includes a mounting plate disposed on the moving part of the transfer guide rail. A bottom clamping plate is fixedly disposed at the end of the mounting plate near the other support plate. Side clamping plates are slidably connected to both ends of the bottom clamping plate along the axis of the flipping shaft. A top clamping plate is slidably connected to each side clamping plate. A driving assembly is disposed on the bottom clamping plate. The driving assembly drives the side clamping plates and the top clamping plates to fix the iron core frame on the bottom clamping plate.

[0013] By adopting the above technical solution, when the feeding component pushes the iron core frame to the bottom clamping plate, the drive component drives the two side clamping plates to slide towards each other along the mounting plate, clamping the two sides of the iron core frame. Then, the drive component drives the top clamping plate to slide down and press the top of the iron core frame, thus fixing the horizontal iron core frame to the bottom clamping plate, reducing the risk of displacement and shaking of the iron core frame during the flipping process, and ensuring that the iron core frame can be flipped with the rotation of the bearing plate. After flipping, the transfer guide rail starts to drive the mounting plate and the iron core frame fixed on the mounting plate to move, realizing the transfer of the vertical iron core frame.

[0014] Optionally, the drive assembly includes a guide block fixedly mounted on the side clamping plate, a guide groove slidably engaged with the guide block on the bottom clamping plate, a drive cylinder corresponding to each of the two guide blocks at the bottom of the bottom clamping plate, the piston rod end of the drive cylinder being mounted on the corresponding guide block, and the guide block pulling the side clamping plate against the surface of the iron core frame when the piston rod of the drive cylinder retracts, a moving groove being provided inside the side clamping plate, a moving block slidably connected to the moving groove on the top clamping plate, a fastening screw being rotatably connected inside the moving groove, the moving block being threadedly connected to the fastening screw, and a drive motor for driving the fastening screw to rotate on the side clamping plate.

[0015] By adopting the above technical solution, when the iron core frame is transferred to the top of the bottom clamping plate, the piston rods of the two drive cylinders retract synchronously, pulling the side clamping plate toward the outer surface of the iron core frame until the side clamping plate abuts against the outer surface of the iron core frame. Then, the drive motor drives the fastening screw to rotate. Under the limit of the moving slot and the moving block, the fastening screw rotates the top clamping plate toward the iron core frame until the top clamping plate abuts against the top surface of the iron core frame. In this way, the horizontal iron core frame is fixed on the bottom clamping plate, thus achieving the fixation of the iron core frame.

[0016] Optionally, the feeding assembly includes a pushing cylinder disposed along the length of the frame, a pushing plate disposed on the moving part of the pushing cylinder, and multiple guide rollers rotatably connected to both the frame and the bearing plate near the feeding station. The top cut surface of the guide rollers is flush with the bottom clamping plate, and the pushing plate pushes the iron core frame to abut against the mounting plate.

[0017] By adopting the above technical solution, when the horizontal iron core frame moves to the loading station, the pushing cylinder is activated, which drives the pushing plate to move towards the bearing plate. The pushing plate pushes the iron core frame to slide along the guide roller. Since the top tangent of the guide roller is flush with the bottom clamping plate, it can ensure that the iron core frame is smoothly transferred to the bottom clamping plate until the iron core frame abuts against the mounting plate, thereby stably transferring the horizontal iron core frame to the surface of the bottom clamping plate, providing positioning for the subsequent clamping operation of the fixing components.

[0018] Optionally, a first sensor is embedded in the mounting plate, and the first sensor is electrically connected to the drive cylinder through a control system. A second sensor is provided on the side clamp, and the second sensor is electrically connected to the drive motor through a control system. A third sensor for detecting the position of the side clamp is provided at the end of the support plate near the discharge station, and the third sensor is electrically connected to the drive cylinder and the drive motor through a control system.

[0019] By adopting the above technical solution, when the iron core frame is pushed and abuts against the mounting plate, the first sensor detects that the iron core frame is in place. The control system triggers the start of the drive cylinder, which drives the side clamping plate and the top clamping plate to move and achieve clamping and fixation. After the side clamping plate clamps the iron core frame, the second sensor detects that the lateral clamping is in place through pressure sensing. The control system controls the start of the drive motor, which drives the top clamping plate to abut against the surface of the iron core frame. When the mounting plate moves the side clamping plate to the discharge station, the third sensor detects the sensing plate. The control system controls the drive cylinder and drive motor to release the side clamping plate and the top clamping plate, which facilitates the subsequent unloading operation. This achieves automated control of the flipping operation, reduces manual intervention, and improves the accuracy and efficiency of the operation.

[0020] Optionally, both the side clamps and the top clamps are provided with shock-absorbing rubber pads, which abut against the outer surface of the iron core frame.

[0021] By adopting the above technical solution, the shock-absorbing rubber pad can buffer the impact force when the fixed component is clamped, and at the same time absorb the vibration generated during the flipping process, reduce the impact of vibration on the silicon steel sheets in the iron core frame, and prevent the silicon steel sheets from loosening or being damaged.

[0022] In summary, this application includes at least one of the following beneficial technical effects: This application sets up a flipping shaft, four bearing plates and a flipping assembly. The flipping assembly drives the flipping shaft to rotate, and the rotation of the flipping shaft drives the four bearing plates to rotate 90° synchronously. At this time, the bearing plate carrying the iron core frame rotates to the unloading station, and the iron core frame changes from a horizontal to a vertical state. During this process, the next flipping station moves to the side closer to the loading station, realizing the continuous flipping operation of the iron core frame without waiting for the previous flipping station to reset, shortening the single iron core flipping cycle, thereby improving the iron core flipping efficiency. This application sets up a fixing component and a driving component. The driving component drives two side clamps to slide towards each other along the mounting plate to clamp the two sides of the iron core frame. Then the driving component drives the top clamp to slide down and press the top of the iron core frame. In this way, the horizontal iron core frame is fixed on the bottom clamp, reducing the risk of displacement and shaking of the iron core frame during the flipping process and ensuring that the iron core frame can be flipped with the rotation of the bearing plate. This application achieves automated control of the flipping operation by setting up a first sensor, a second sensor, and a third sensor, and through the cooperation of the three sensors, the fixed components are automatically triggered and released, thereby reducing manual intervention and improving the accuracy and efficiency of the operation.

Detailed Implementation

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a transformer core fastening and flipping device.

[0030] Reference Figure 1 and Figure 2 A transformer core fastening and turning device includes a frame 1. The two ends of the frame 1 along its length are a loading station 101 and a unloading station 102, respectively. The loading station 101 is connected to the conveying device of the previous process. The unloading station 102 can be equipped with an unloading robot (not shown in the figure). The loading station 101 is provided with a loading component 2. Specifically, the loading component 2 includes a pushing cylinder 21 fixedly installed on the surface of the frame 1. The pushing cylinder 21 is arranged along the length of the frame 1. It should be noted that the transmission device of the previous process is perpendicular to the length of the frame 1. A pushing plate 22 is fixedly installed on the moving part of the pushing cylinder 21. Multiple guide rollers 23 are rotatably connected to the frame 1 along its length.

[0031] Reference Figure 2 and Figure 3 The frame 1 is located between the loading station 101 and the unloading station 102 and has a tilting groove 103. A tilting shaft 3 is rotatably connected to the center of the tilting groove 103. In this embodiment, both ends of the tilting shaft 3 are rotatably connected to the side wall of the tilting groove 103 through bearings. A tilting assembly 5 is provided on the frame 1. Specifically, the tilting assembly 5 includes a tilting motor 51 fixedly installed on the frame 1. The output shaft of the tilting motor 51 is connected to a drive gear 53 through a reduction gearbox 52. The end of the tilting shaft 3 is coaxially fixedly connected to a driven gear 54 that meshes with the drive gear 53.

[0032] Reference Figure 2 and Figure 3Four bearing plates 4 are fixedly connected to the outer surface of the flipping shaft 3. The four bearing plates 4 are evenly distributed around the circumference of the flipping shaft 3. A flipping station 41 is formed between the opposite surfaces of two adjacent bearing plates 4 in the circumferential direction. The flipping station 41 is located on the surface of one of the bearing plates 4, which is provided with a fixing component 6 and a transfer component 7. Multiple guide rollers 23 that are connected to the frame 1 are rotatably connected to the surface of the other bearing plate 4.

[0033] Reference Figure 2 and Figure 3 The transfer component 7 is a transfer guide rail fixedly installed on the surface of the bearing plate 4. The fixing component 6 includes a mounting plate 61 fixedly installed on the moving part of the transfer guide rail. A bottom clamping plate 62 is fixedly connected to the end of the mounting plate 61 near the other bearing plate 4. The top cut surface of the guide roller 23 is flush with the bottom clamping plate 62, thus ensuring the smooth transfer of the horizontal guide rail. Side clamping plates 63 are slidably connected to both ends of the bottom clamping plate 62 along the axis of the flipping shaft 3. A top clamping plate 64 is slidably connected to each side clamping plate 63. Shock-absorbing rubber pads 65 are installed on the end faces of the top clamping plate 64 and the side clamping plates 63 facing the iron core frame 01, thereby reducing the impact of vibration on the silicon steel sheets inside the iron core frame 01 and preventing the silicon steel sheets from loosening or being damaged. A driving component 8 is provided on the bottom clamping plate 62 to drive the side clamping plates 63 and the top clamping plate 64 to fix the iron core frame 01 on the bottom clamping plate 62.

[0034] During operation, the conveying device of the previous process sequentially transfers the horizontal iron core frame 01 to the loading station 101 of the frame 1. Then, the pushing cylinder 21 is activated, driving the pushing plate 22 to move towards the bearing plate 4. The pushing plate 22 pushes the iron core frame 01 to slide along the guide roller 23. Since the top cut surface of the guide roller 23 is flush with the bottom clamping plate 62, the iron core frame 01 slides along the guide roller 23 onto the bottom clamping plate 62 and finally abuts against the mounting plate 61. Subsequently, the drive assembly 8 drives the two side clamps 63 to slide towards each other along the mounting plate 61, clamping the two sides of the iron core frame 01. The drive assembly 8 then drives the top clamp 64 to slide downwards and press the top of the iron core frame 01, thus fixing the horizontal iron core frame 01 onto the bottom clamp 62, reducing the risk of displacement or shaking of the iron core frame 01 during the flipping process. After being fixed, the tilting motor 51 starts. The power of the output shaft of the tilting motor 51 is transmitted to the drive gear 53 after being reduced and increased in torque by the reduction gearbox 52. The drive gear 53 drives the meshing driven gear 54 to rotate. The driven gear 54 drives the tilting shaft 3 to rotate. The rotation of the tilting shaft 3 drives the four bearing plates 4 to rotate 90° synchronously. At this time, the bearing plate 4 carrying the iron core frame 01 rotates to the side closer to the unloading station 102, and the iron core frame 01 changes from a horizontal to a vertical state. Next, the transfer guide rail is activated, moving the mounting plate 61 and the vertical iron core frame 01 on its surface to the side near the unloading station 102. The drive component 8 drives the side clamping plate 63 and the top clamping plate 64 away from the iron core frame 01. After the clamping is released, the unloading robot at the unloading station 102 unloads the vertical iron core frame 01, thus realizing the flipping operation of one iron core frame 01. Then, the loading component 2 transfers the next iron core frame 01 to be flipped to the empty bearing plate 4 near the loading station 101. The above flipping process is repeated. During the flipping of the next iron core frame 01, the transfer guide rail at the previous flipping station 41 drives the mounting plate 61 to reset to the initial position so as to bear the subsequent iron core frame 01. In this way, the continuous flipping operation of the iron core frame 01 is realized without waiting for the previous flipping station 41 to reset, shortening the single iron core flipping cycle and thus improving the iron core flipping efficiency.

[0035] Reference Figure 3 and Figure 4 Each bearing plate 4 is fixedly connected to a mounting shaft 9 at the end away from the flipping shaft 3. Guide wheels 91 are fixedly connected to both ends of the mounting shaft 9 on the same axis. Guide frames 93 that roll with the guide wheels 91 are fixedly installed on the wall of the flipping groove 103 and the frame 1. During the rotation of the flipping shaft 3, the guide wheels 91 on the mounting shaft 9 roll along the guide frames 93, thereby reducing the friction when the bearing plate 4 rotates, ensuring that the rotation process of the bearing plate 4 is more stable, and reducing the possibility of the bearing plate 4 shaking and shifting due to uneven force.

[0036] Reference Figure 3 and Figure 4 The drive assembly 8 includes a guide block 81 fixedly installed on the side clamping plate 63. The bottom clamping plate 62 has a guide groove 621 that slides with the guide block 81. The bottom of the bottom clamping plate 62 is equipped with a drive cylinder 82 that corresponds to the two guide blocks 81. The drive cylinders 82 are all located at the center of the bottom clamping plate 62 and are arranged symmetrically about the center of the bottom clamping plate 62. The end of the guide block 81 extends to the bottom of the bottom clamping plate 62 and is connected to the piston rod of the corresponding drive cylinder 82. When the piston rod of the drive cylinder 82 retracts, the guide block 81 pulls the side clamping plate 63 to abut against the surface of the iron core frame 01.

[0037] Reference Figure 3 and Figure 4 The two side clamps 63 have moving grooves 631 on their opposite surfaces. A moving block 83 is fixedly connected to the top clamp 64 and slidably connected in the moving groove 631. The moving block 83 and the moving groove 631 have square cross sections to limit their relative rotation. A fastening screw 84 is rotatably connected inside the moving groove 631. The moving block 83 is threadedly connected to the fastening screw 84. A drive motor 85 is fixedly installed on the top of the side clamps 63. The output shaft of the drive motor 85 is coaxially fixedly connected to the fastening screw 84.

[0038] Reference Figure 3 and Figure 4 A first sensor (not shown in the figure) is fixedly embedded on the mounting plate 61. The first sensor is electrically connected to the drive cylinder 82 through the control system. A second sensor (not shown in the figure) is fixedly embedded on the opposite surfaces of the two side clamps 63. The second sensor is electrically connected to the drive motor 85 through the control system. Both the first and second sensors are pressure sensors. A third sensor 10 for detecting the position of the side clamps 63 is installed at the end of the bearing plate 4 near the discharge station. The third sensor 10 is electrically connected to the drive cylinder 82 and the drive motor 85 through the control system. The third sensor 10 is a proximity sensor in the prior art.

[0039] When the pushing assembly pushes the core frame 01 to abut against the mounting plate 61, the first sensor senses the pressure to determine that the core frame 01 is in place. The first sensor triggers the drive cylinder 82 to start through the control system. The piston rods of the two drive cylinders 82 retract synchronously, pulling the side clamping plate 63 toward the outer surface of the core frame 01 until the side clamping plate 63 abuts against the outer surface of the core frame 01. At this time, the second sensor detects that the lateral clamping is in place through pressure sensing. The control system controls the drive motor 85 to start. Under the limit of the moving slot 631 and the moving block 83, the fastening screw 84 rotates the top clamping plate 64 to move toward the core frame 01 until the top clamping plate 64 abuts against the top surface of the core frame 01, thus fixing the core frame 01. When the transfer guide rail moves the mounting plate 61 to the discharge station, the third sensor 10 detects that the side clamp 63 has moved into place. The control system controls the drive cylinder 82 and drive motor 85 to release the side clamp 63 and the top clamp 64, which facilitates the subsequent unloading operation. This achieves automated control of the flipping operation, reduces manual intervention, and improves the accuracy and efficiency of the operation.

[0040] The implementation principle of the transformer core fastening and turning device in this application embodiment is as follows: During operation, the conveying device of the previous process sequentially transmits the horizontal core frame 01 to the loading station 101 of the frame 1. Then, the pushing cylinder 21 is activated, driving the pushing plate 22 to move towards the bearing plate 4. The pushing plate 22 pushes the core frame 01 to slide along the guide roller 23. Since the top cut surface of the guide roller 23 is flush with the bottom clamping plate 62, the core frame 01 slides along the guide roller 23 onto the bottom clamping plate 62 and finally abuts against the mounting plate 61. Then, the drive assembly 8 drives two The side clamping plates 63 slide towards each other along the mounting plate 61, clamping the two sides of the iron core frame 01. The drive assembly 8 drives the top clamping plate 64 to slide downwards and press against the top of the iron core frame 01, thus fixing the horizontal iron core frame 01 onto the bottom clamping plate 62, reducing the risk of displacement or shaking of the iron core frame 01 during the flipping process. After fixing, the flipping motor 51 starts. The power from the output shaft of the flipping motor 51 is transmitted to the drive gear 53 after being reduced in speed and torque by the reduction gearbox 52. The drive gear 53 drives the meshing driven gear 54 to rotate, and the driven gear 54 drives the flipping shaft. 3. Rotation: The rotation of the rotating shaft 3 drives the four bearing plates 4 to rotate synchronously by 90°. At this time, the bearing plate 4 carrying the iron core frame 01 rotates to the side closer to the unloading station 102, and the iron core frame 01 changes from a horizontal to a vertical state. Then, the transfer guide rail starts, driving the mounting plate 61 and the vertical iron core frame 01 on its surface to the side closer to the unloading station 102. The drive assembly 8 drives the side clamping plate 63 and the top clamping plate 64 away from the iron core frame 01. After the clamping is released, the unloading robot at the unloading station 102 unloads the vertical iron core frame 01. This achieves the flipping operation of one iron core frame 01. Subsequently, the feeding assembly 2 transfers the next iron core frame 01 to be flipped to the empty bearing plate 4 near the feeding station 101. The above flipping process is repeated. During the flipping of the next iron core frame 01, the transfer guide rail at the previous flipping station 41 drives the mounting plate 61 to reset to the initial position so as to bear the subsequent iron core frame 01. In this way, the continuous flipping operation of the iron core frame 01 is realized without waiting for the previous flipping station 41 to reset, which shortens the single iron core flipping cycle and thus improves the iron core flipping efficiency.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
