Technical Field
[0001] This utility model relates to the technical field of silicon steel sheet processing equipment, specifically a silicon steel sheet stamping positioning table transfer device. Background Technology
[0002] Silicon steel sheet laminations are core components of electrical equipment such as motors and transformers. Their processing quality and turnover efficiency directly affect the performance and production progress of downstream equipment. In the large-scale production process of silicon steel sheet laminations, after the positioning table completes the precise positioning of the laminations, they need to be smoothly transported to the next process such as stamping and stacking through a transfer device. The transfer link is a key node connecting positioning and subsequent processing, and its stability, adaptability, and protective performance have an important impact on overall production efficiency and product quality.
[0003] The current silicon steel sheet stamping transfer methods used in the industry generally suffer from insufficient adaptability and accuracy. On the one hand, traditional transfer devices mostly rely on simple conveying structures to transfer the stampings, lacking effective automatic positioning functions. During the conveying process, the stampings are prone to deviation due to factors such as vibration and inertia, requiring additional manual calibration upon arrival at the next process. This not only disrupts the continuity of the production process but also increases labor costs. In addition, the existing transfer devices often require manual intervention to unlock the positioning components during the sheet retrieval stage. The operation process is cumbersome, inefficient, and may cause secondary deviation or damage to the stampings due to improper manual operation, further exacerbating quality risks and efficiency losses in the production process. Utility Model Content
[0004] The purpose of this utility model is to provide a silicon steel sheet stamping positioning platform transfer device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a silicon steel sheet stamping positioning platform transfer device, comprising a conveyor belt frame, a conveyor belt arranged between the two sides of the conveyor belt frame, several sets of holding boxes fixedly connected to the outer side of the conveyor belt, four sets of moving grooves opened on the outer side of the holding boxes, a moving cylinder slidably connected inside the moving groove, a connecting rod rotatably connected inside the moving cylinder, a positioning plate fixedly connected to one end of the connecting rod, a connecting block fixedly connected to one end of the moving cylinder penetrating into the holding box, a sliding box slidably connected to the outer side of the connecting block, a receiving lug fixedly connected to the lower middle part of the sliding box, a threaded rod threadedly connected inside the receiving lug, a first bevel gear fixedly connected to one end of the threaded rod rotatably connected to the inner wall of the holding box, a second bevel gear meshing between the first bevel gears, the tail of the second bevel gear rotatably connected to the inner wall of the holding box, a connecting gear fixedly connected to one side of the threaded rod penetrating the holding box, a first rack and a second rack fixedly connected to one side of the conveyor belt frame, the first rack and the second rack meshing with the upper and lower sides of the connecting gear respectively.
[0006] Preferably, the positioning plate has a flat side and an arc-shaped side.
[0007] Preferably, rubber pads are bonded to both sides of the positioning plate.
[0008] Preferably, two sets of guide rods are fixedly connected inside the sliding box, the guide rods are slidably connected inside the connecting block, and a first spring is fixedly connected between the connecting block and the sliding box, the first spring being sleeved on the outside of the guide rods.
[0009] Preferably, the movable cylinder has a lifting groove inside, one end of the connecting rod penetrates into the lifting groove and is fixedly connected to a connecting piece, the other end of the connecting piece is fixedly connected to four sets of locking rods, and the movable cylinder has a locking hole that matches the locking rods.
[0010] Preferably, a second spring is fixedly connected to the inner wall of the lifting groove, and the second spring is sleeved on the outside of the connecting rod.
[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, during the transfer process, when the container moves with the conveyor belt, the connecting gear meshes with the first rack to drive the threaded rod to rotate. Through bevel gear transmission, four sets of positioning plates move synchronously inward, pushing the punch to the center of the container to complete the centering positioning. When the container moves with the conveyor belt to the discharge end, the connecting gear meshes with the second rack, driving the threaded rod to rotate in the opposite direction, causing the positioning plate to move outward and disengage from the punch, automatically releasing the positioning state, automatically centering positioning, and automatically unlocking and removing the punch, thus improving the convenience and efficiency of operation. 2. This utility model also features a positioning plate designed as a dual-adaptive structure with one side flat and the other curved. When transferring between different shaped stampings, simply press the connecting rod to compress the second spring, causing the locking rod to disengage from the locking hole. Rotate the connecting rod to switch the orientation of the positioning plate. After releasing, the spring returns to its original position, locking the angle. Without disassembling or replacing the positioning components, it can adapt to silicon steel stampings of different shapes, such as round and square, significantly improving the equipment's adaptability to diverse processing needs and reducing the time spent on equipment adjustments due to changes in processing specifications. 3. This invention also utilizes a positioning plate that approaches and contacts the lamination. As the sliding box continues to move, it compresses the first spring. The spring, through its elasticity, buffers the positioning force, preventing excessive pressure from the positioning plate on the lamination. This ensures stable positioning of the lamination, prevents deformation due to excessive force, and protects the insulation layer on the silicon steel sheet from scratches, reducing waste and ensuring the insulation performance and structural stability of subsequent equipment such as motors and transformers.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-3This utility model provides a technical solution: a silicon steel sheet stamping positioning platform transfer device, including a conveyor belt frame 1, a conveyor belt 2 is arranged between the two sides of the conveyor belt frame 1 through a conveyor belt roller, and a number of holding boxes 5 are bolted to the outer side of the conveyor belt 2 along its length. The holding boxes 5 are used to receive the falling silicon steel sheet stampings. Four sets of moving grooves 6 are evenly opened around the outer side of the holding boxes 5. The moving grooves 6 are slidably connected to the moving cylinders 7 through clearance fit. The moving cylinders 7 are rotatably connected to the moving cylinders 7. The end of the connecting rod 8 away from the moving cylinder 7 is bolted. A positioning plate 9 is fixedly connected to the movable cylinder 7, and a connecting rod 8 can rotate around the movable cylinder 7 to adjust the direction of the positioning plate 9. One end of the movable cylinder 7 penetrates into the interior of the container 5 and is fixedly connected to a connecting block 10 by welding. A sliding box 11 is slidably connected to the outside of the connecting block 10 by clearance fit. A lug 12 is fixedly connected to the lower middle part of the sliding box 11 by welding. A threaded rod 13 is threadedly connected inside the lug 12. One end of the threaded rod 13 is rotatably connected to the inner wall of the container 5 by a deep groove ball bearing to ensure smooth rotation of the threaded rod 13. The other end of the threaded rod 13 is fixedly connected to a first bevel gear 1 by a key. 4. The four sets of first bevel gears 14 are meshed with second bevel gears 15. The tail of the second bevel gear 15 is rotatably connected to the inner wall of the container 5 through a deep groove ball bearing. The second bevel gear 15 is used to realize the synchronous rotation of the four sets of threaded rods 13, ensuring that the positioning plate 9 moves synchronously from four sides. One side of the threaded rod 13 penetrates one end of the container 5 and is fixed to a connecting gear 16 by a key. The conveyor belt frame 1 is fixedly connected to a first rack 3 and a second rack 4 by bolts on one side. The first rack 3 is located on the feed end side of the conveyor belt 2, and the second rack 4 is located on the discharge end side of the conveyor belt 2, and they mesh with each other. The connecting gear 16 is connected to the upper and lower sides of the connecting gear 16. When the holding box 5 moves with the conveyor belt 2, the connecting gear 16 meshes with the rack and rotates, driving the threaded rod 13 to rotate synchronously, which in turn drives the positioning plate 9 to move. When the holding box 5 moves with the conveyor belt 2 to the discharge end, the connecting gear 16 meshes with the second rack 4. The second rack 4 drives the connecting gear 16 to rotate in the opposite direction, driving the threaded rod 13 to rotate in the opposite direction. The four sets of threaded rods 13 rotate in the opposite direction synchronously. The sliding box 11 drives the moving cylinder 7 to move outward along the moving groove 6. The positioning plate 9 disengages from the punch in the holding box 5, releasing the positioning and facilitating the removal of the punch. The four sets of threaded rods 13 rotate synchronously in opposite directions. The sliding box 11 drives the moving cylinder 7 to move outward along the moving groove 6. The positioning plate 9 disengages from the punch in the holding box 5, releasing the positioning and making it easier to remove the punch. The positioning plate 9 has a flat side and an arc side. The flat side is suitable for square stamping pieces, and the arc side is suitable for round stamping pieces. Rubber pads are bonded to both sides of the positioning plate 9; Two sets of guide rods 17 are fixedly connected to the inside of the sliding box 11 by welding. The outer side of the guide rods 17 is slidably connected to the inside of the connecting block 10 by clearance fit, providing guidance for the sliding of the connecting block 10 and preventing deviation. A first spring 18 is fixedly connected to the inner wall of the sliding box 11 by spot welding between the connecting block 10 and the inner wall of the sliding box 11. The first spring 18 is sleeved on the outer side of the guide rods 17 and is in a natural state under normal conditions. When the positioning plate 9 moves too much, the first spring 18 is compressed to buffer and prevent excessive squeezing of the punches in the holding box 5. The movable cylinder 7 has a lifting groove 19 inside. One end of the connecting rod 8 penetrates into the lifting groove 19 and is fixedly connected to the connecting piece 20 by welding. The other end of the connecting piece 20 is fixedly connected to four sets of locking rods 21 by welding. The movable cylinder 7 has locking holes 22 that cooperate with the locking rods 21 evenly opened along the circumference inside. The inner wall of the lifting groove 19 is fixedly connected to the second spring 23 by spot welding. The second spring 23 is sleeved on the outside of the connecting rod 8. Under normal conditions, it pushes the connecting piece 20 so that the locking rod 21 is inserted into the locking hole 22, fixing the angle of the positioning plate 9 and ensuring the positioning and adaptation of different shaped punch pieces in the holding box 5.
[0016] Working principle: When using this utility model: according to the shape of the silicon steel sheet to be transferred, the connecting rod 8 is pulled upward to compress the second spring 23, the locking rod 21 is disengaged from the locking hole 22 of the moving cylinder 7, the connecting rod 8 is rotated so that the arc side of the positioning plate 9 faces the inside of the holding box 5, the connecting rod 8 is released, the second spring 23 is reset and pushes the connecting piece 20, the locking rod 21 is inserted into the corresponding locking hole 22 to fix the angle of the positioning plate 9. If it is a square sheet, the flat side of the positioning plate 9 faces the inside of the holding box 5. When conveyor belt 2 starts, the container 5 moves with conveyor belt 2 to below the feed end, dropping the silicon steel sheet. The sheet falls into the middle of the container 5. At this time, the connecting gear 16 is not engaged with the first rack 3, and the positioning plate 9 is in the initial outer position, which does not affect the sheet falling into the container 5. As the container 5 continues to move with conveyor belt 2, the connecting gear 16 engages with the first rack 3. The movement of conveyor belt 2 drives the connecting gear 16 to rotate, which in turn drives the threaded rod 13 on one side to rotate. The threaded rod 13 on one side drives the first bevel gear 14 to rotate. The first bevel gear 14 engages with the second bevel gear 15, driving the other three sets of first bevel gears 14 to rotate synchronously. Four sets of threaded rods 13 rotate synchronously; the threaded rods 13 drive the lugs 12 and the sliding box 11 to move inward, the connecting block 10 slides along the guide rod 17, the moving cylinder 7 slides inward along the moving groove 6, and the positioning plate 9 moves towards the punch in the holding box 5 synchronously; when the positioning plate 9 contacts the punch in the holding box 5, the moving sliding box 11 compresses the first spring 18, the first spring 18 buffers the positioning force to avoid excessive compression that could deform the punch or damage the insulation layer; until the punch is pushed to the center of the holding box 5 by the four side positioning plates 9 to achieve centered positioning, at which point the first spring 18 is in a slightly compressed state to maintain the positioning force; The holding box 5 moves to the discharge end with the conveyor belt 2, and the connecting gear 16 meshes with the second rack 4; the second rack 4 drives the connecting gear 16 to rotate in the opposite direction, which in turn drives the threaded rod 13 to rotate in the opposite direction; the four sets of threaded rods 13 rotate in the opposite direction synchronously, and the sliding box 11 drives the moving cylinder 7 to move outward along the moving groove 6, and the positioning plate 9 disengages from the punch in the holding box 5, releasing the positioning; the conveyor belt 2 drives the holding box 5 to the piece picking station, and the manual or robotic arm takes out the centered punch from the holding box 5 and puts it into the next process equipment; the holding box 5 continues to move in a cycle with the conveyor belt 2, ready to receive the next punch.
