Technical Field

[0001] This utility model relates to the field of motor core processing technology, and in particular to a motor core stacking structure. Background Technology

[0002] The laminated core structure of a motor is the core magnetic conductive component of the motor. It is made of multiple layers of silicon steel sheets through processes such as stamping, insulation, stacking, and consolidation. It is used to construct an efficient magnetic circuit, suppress eddy current losses, and support the electromagnetic windings. Its performance directly affects the motor's efficiency, power density, temperature rise, and vibration and noise levels.

[0003] Patent CN205490023U discloses a motor core stacking structure, which provides a structure for consolidating various silicon steel laminations. It has the advantages of simple structure, convenient use and improved product quality. However, when using this motor core stacking structure, it can usually only stack motor cores with a specific inner diameter, and its use is relatively limited. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a motor core stacking structure. Existing motor core stacking structures can usually only be used to stack motor cores of a specific inner diameter, which has relatively large limitations.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is a motor core stacking structure, including a bearing base set on the upper side of a support base plate, an mounting ring plate fixedly connected in the middle of the support base plate, a first motor set on the inner side of the mounting ring plate, a rotating shaft fastened to the output end of the first motor, a main bevel gear fastened on the rotating shaft, and six sets of driven bevel gears set in the middle of the bearing base, with a transverse threaded rod passing through the driven bevel gears;

[0006] A sliding block is sleeved on the transverse threaded rod, and limit blocks are fixedly connected to both sides of the sliding block. A fixed shaft is fixedly connected to the upper side of the sliding block, and a movable tube is movably sleeved on the fixed shaft.

[0007] A second motor is fixedly installed in the middle of the upper side of the support base. The output end of the second motor is fixedly connected to a vertical lead screw shaft. A stacking plate is sleeved on the vertical lead screw shaft. Several sets of limiting vertical rods are fixedly connected to the support base.

[0008] As a further embodiment of this utility model: the bevel gear is threadedly connected to the transverse threaded rod, and the transverse threaded rod is threadedly connected to the sliding block.

[0009] As a further embodiment of this utility model: six sets of limiting slides are equally spaced through the bearing base, and the sliding block is slidably disposed inside the limiting slide through the limiting block.

[0010] As a further embodiment of this utility model: a threaded hole is provided through the middle of the stacking plate, and the vertical lead screw shaft is threadedly connected to the stacking plate through the threaded hole. Several sets of sliding holes are equally spaced through the stacking plate, and the limiting vertical rod is movably connected to the stacking plate through the sliding hole.

[0011] As a further embodiment of this utility model: a number of connecting rods are fixedly connected to the upper edge of the supporting base plate, and the top of the connecting rods is threaded with a threaded ring. Four sets of mounting rods are fixedly connected to the first motor at equal intervals.

[0012] As a further embodiment of this utility model: several sets of connecting rods are evenly distributed on the support base plate, and several sets of connecting slots are evenly spaced through the bearing base, with the connecting rods located inside the connecting slots, and the mounting rods cooperate with the mounting ring plate.

[0013] Compared with the prior art, the beneficial effects of this utility model include: by starting the first motor to drive the rotating shaft and the main bevel gear to rotate together, the meshing main bevel gear and the driven bevel gear drive the six sets of horizontal threaded rods to rotate together. Then, through the threaded connection between the horizontal threaded rods and the sliding block, the sliding block is driven to move along the limiting slide. At this time, the six sets of fixed shafts move together until the six sets of movable tubes are tightly attached to the inner walls of several sets of silicon steel sheets. Then, the second motor on the upper side of the bearing base is started to drive the vertical screw shaft to rotate. Through the threaded connection between the vertical screw shaft and the stacking plate, the limiting action of the limiting vertical rod and the sliding hole allows the stacking plate to move downward until several sets of silicon steel sheets are stacked. This allows for the stacking operation of motor cores with different inner diameters, significantly improving the applicability of the device.

[0014] Compared with the prior art, the beneficial effects of this utility model include: firstly, starting the first motor causes the six sets of sliding blocks to move out of the bearing base together, then starting the second motor causes the stacking plate to be removed from the device, then removing the screw ring on the connecting rod, and separating the support base plate from the bearing base through the cooperation of the connecting rod and the connecting groove. At this time, the mounting ring plate is separated from the first motor through the four sets of mounting rods, which enables the rapid replacement of faulty local parts and facilitates maintenance.

Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] Example 1, please refer to Figures 1-4 A motor core stacking structure includes a bearing base 1 mounted on the upper side of a supporting base plate 2. A mounting ring plate 3 is fixedly connected to the middle of the supporting base plate 2. A first motor 4 is mounted inside the mounting ring plate 3. A rotating shaft 5 is fixedly connected to the output end of the first motor 4. A main bevel gear 6 is fixedly sleeved on the rotating shaft 5. Six sets of driven bevel gears 7 are arranged in the middle of the bearing base 1. A horizontal threaded rod 8 is passed through the driven bevel gears 7. A sliding block 9 is sleeved on the horizontal threaded rod 8. Limiting blocks 10 are fixedly connected to both sides of the sliding block 9. A fixed shaft rod 12 is fixedly connected to the upper side of the sliding block 9. A movable tube 13 is movably sleeved on the fixed shaft rod 12. A second motor 14 is fixedly mounted in the middle of the upper side of the bearing base 1. A vertical lead screw shaft 15 is fixedly connected to the output end of the second motor 14. A stacking plate 16 is sleeved on the vertical lead screw shaft 15. Several sets of limiting vertical rods 18 are fixedly connected to the bearing base 1.

[0022] The bevel gear 7 is threadedly connected to the transverse threaded rod 8, and the transverse threaded rod 8 is threadedly connected to the sliding block 9.

[0023] In this embodiment, the rotation of the transverse threaded rod 8 is achieved through meshing of the main bevel gear 6 and the driven bevel gear 7.

[0024] The support base 1 has six sets of limiting slides 11 with equal spacing, and the sliding block 9 is slidably set inside the limiting slide 11 through the limiting block 10.

[0025] In this embodiment, the sliding block 9 is moved by the cooperation of the limiting block 10 and the limiting slide 11.

[0026] A threaded hole 17 is provided through the middle of the stacked plate 16, and the vertical lead screw shaft 15 is threadedly connected to the stacked plate 16 through the threaded hole 17. Several sets of sliding holes 19 are equally spaced through the stacked plate 16, and the limiting vertical rod 18 is movably connected to the stacked plate 16 through the sliding holes 19.

[0027] In this embodiment, the vertical lead screw shaft 15 is threadedly connected to the stacking plate 16 to limit the vertical rod 18 and the sliding hole 19 so that the stacking plate 16 can be raised and lowered.

[0028] Specifically, by starting the first motor 4, the rotating shaft 5 and the main bevel gear 6 are rotated together. The meshing main bevel gear 6 and the driven bevel gear 7 drive the six sets of horizontal threaded rods 8 to rotate together. Then, through the threaded connection between the horizontal threaded rods 8 and the sliding block 9, the sliding block 9 is moved along the limiting slide 11 by the limiting block 10. At this time, the six sets of fixed shaft rods 12 move together until the six sets of movable tubes 13 are tightly attached to the inner wall of several sets of silicon steel sheets. Then, the second motor 14 on the upper side of the bearing base 1 is started to drive the vertical screw shaft 15 to rotate. Through the threaded connection between the vertical screw shaft 15 and the stacking plate 16, the limiting action of the limiting vertical rod 18 and the sliding hole 19 allows the stacking plate 16 to move downward until several sets of silicon steel sheets are stacked. This allows for the stacking operation of motor cores with different inner diameters, significantly improving the applicability of the device.

[0029] Example 2, please refer to Figures 1-4 A motor core stacking structure includes a bearing base 1 mounted on the upper side of a supporting base plate 2.

Six sets of driven bevel gears 7 are arranged in the middle of the bearing base 1. A horizontal threaded rod 8 is passed through the driven bevel gears 7. A sliding block 9 is sleeved on the horizontal threaded rod 8. Limiting blocks 10 are fixedly connected to both sides of the sliding block 9. A fixed shaft rod 12 is fixedly connected to the upper side of the sliding block 9. A movable tube 13 is movably sleeved on the fixed shaft rod 12.

A stacking plate 16 is sleeved on the vertical lead screw shaft 15. Several sets of limiting vertical rods 18 are fixedly connected to the bearing base 1.

[0030] Several sets of connecting rods 20 are fixedly connected to the upper edge of the support base plate 2. The top of the connecting rod 20 is threaded with a screw ring 22. Four sets of mounting rods 23 are fixedly connected to the first motor 4 at equal intervals. Several sets of connecting rods 20 are distributed at equal intervals on the support base plate 2. Several sets of connecting slots 21 are opened through the bearing base 1 at equal intervals. The connecting rods 20 are located inside the connecting slots 21.

[0031] In this embodiment, the connecting rod 20 and the connecting slot 21 are used in conjunction with the screw ring 22 to connect the support base 1 and the support base plate 2.

[0032] Specifically, the first motor 4 is started first, causing the six sets of sliding blocks 9 to move off the support base 1 together. Then, the second motor 14 is started, allowing the stacking plate 16 to be removed from the device. Next, the screw ring 22 on the connecting rod 20 is removed, and the support base plate 2 is separated from the support base 1 through the cooperation of the connecting rod 20 and the connecting slot 21. At this time, the mounting ring plate 3 is separated from the first motor 4 through the four sets of mounting rods 23, which enables the quick replacement of faulty local parts and facilitates maintenance.
