Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a motor stator lamination stacking device. Background Technology

[0002] Traditional lamination devices have many problems in the lamination process of motor stator laminations.

[0003] On the one hand, the positioning of stator laminations is not precise or flexible enough, making it difficult to adapt to stator laminations of different specifications and sizes. This causes the laminations to easily shift during the stacking process, affecting the quality and performance of the motor stator. On the other hand, the surface of stator laminations is easily contaminated with dust, debris and other impurities during processing and transportation. Traditional equipment lacks effective cleaning methods, and these impurities will be trapped between the laminations, which will also have an adverse effect on the quality of the motor stator.

[0004] Therefore, we propose a motor stator lamination stacking device. Utility Model Content

[0005] The main purpose of this utility model is to provide a motor stator lamination stacking device to prevent lamination displacement and impurity inclusion from affecting the quality and performance of the motor stator during the motor stator lamination stacking process, thereby improving the quality and performance of the motor stator and effectively solving the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A motor stator lamination stacking device includes a body, a limiting mechanism at the top of the body, the limiting mechanism including a base, a cylindrical tube inside the base, a first motor fixedly mounted at the bottom of the inner cavity of the cylindrical tube, a first bevel gear fixedly connected to the output shaft of the first motor, four first rotating rods arranged in a ring array rotatably through the outer wall of the cylindrical tube, each of the four first rotating rods having a second bevel gear meshing with the first bevel gear at one end of the inner cavity of the cylindrical tube, a movable cylinder movably mounted at the other end of the four first rotating rods, the rod body of the other end of the first rotating rod being located in the inner cavity of the movable cylinder, and the side wall of the first rotating rod outside the inner cavity of the movable cylinder having an external thread, the inner cavity of the movable cylinder having an internal thread that is screwed to the external thread, the end of the movable cylinder away from the first rotating rod penetrating the base and having an arc-shaped limiting plate for limiting the stator laminations, and a limiting device for limiting the movement direction of the movable cylinder being provided on the outer wall of the cylindrical tube;

[0008] The top of the machine body is provided with multiple air blowing components, and the limiting mechanism is located between the air blowing components. The bottom of the machine body is provided with a drive component for driving the air blowing components. The drive component includes a bracket fixedly connected to the inner wall of the top of the machine body. A second motor is fixedly installed on the outer wall of the bottom end of the bracket. The output shaft of the second motor passes through the bracket and is fixedly connected to a gear plate. Multiple driven gears are rotatably connected to the inner wall of the bottom end of the bracket. The multiple driven gears mesh with the gear plate. The top of the multiple driven gears is fixedly connected to a second rotating rod. The top of the multiple second rotating rods passes through the machine body and is fixedly connected to a third bevel gear. The air blowing component includes a support plate fixedly connected to the top of the machine body. A bevel gear ring is rotatably connected to the side of the support plate. The peripheral side of the third bevel gear meshes with the bevel gear ring. A fan blade is fixedly connected to the inner wall of the bevel gear ring.

[0009] By adopting the above technical solution, the first motor is turned on, and the output shaft of the first motor rotates, driving the first bevel gear to rotate. Because the first bevel gear meshes with the four second bevel gears, the four first rotating rods rotate in a ring array on the outer wall of the cylindrical tube. The end of the first rotating rod with external thread cooperates with the moving tube through internal and external threads. When the first rotating rod rotates, the moving tube will move along the axial direction of the first rotating rod. The moving tube drives the arc-shaped limiting plate to approach or move away from the stator lamination, thereby achieving the limiting operation of the stator lamination. At the same time, the limiting device set on the outer wall of the cylindrical tube can ensure that the moving tube moves only along a specific direction, ensuring that the limiting action is accurate.

[0010] When the second motor is started, its output shaft drives the gear disc to rotate. The gear disc meshes with multiple driven gears, causing the multiple driven gears to rotate, which in turn drives the second rotating rod connected to them to rotate. The third bevel gear at the top of the second rotating rod meshes with the bevel gear ring, driving the bevel gear ring to rotate. Since the fan blades are fixed to the inner wall of the bevel gear ring, the rotation of the bevel gear ring will drive the fan blades to rotate, generating airflow to blow air onto the stator laminations. This can be used to clean the laminations. Multiple air blowing components are arranged around the limiting mechanism, which can blow air onto the stator laminations from different directions to ensure good air blowing effect.

[0011] Furthermore, the limiting device includes a limiting frame located on the upper part of the outer wall of the cylindrical tube, and the limiting frame has a strip-shaped limiting opening.

[0012] By adopting the above technical solution, the limiting frame is fixed on the upper part of the outer wall of the cylindrical tube and serves as the supporting structure for the entire limiting device. The strip-shaped limiting port opened on it is the key to restricting the movement of the cylindrical tube.

[0013] Furthermore, a limiting block is provided protruding at the top edge of the cylindrical tube. The limiting block is inserted into the strip-shaped limiting opening, and the left and right outer walls of the limiting block slide against the left and right inner walls of the strip-shaped limiting opening, respectively.

[0014] By adopting the above technical solution, when the first motor drives the first rotating rod to rotate, causing the moving cylinder to move, the limiting block is inserted into the strip-shaped limiting port, and its left and right outer walls are tightly slidably attached to the left and right inner walls of the strip-shaped limiting port. This structural design is like putting "shackles" on the movement of the cylindrical cylinder, preventing the cylindrical cylinder from shifting and rotating arbitrarily in the horizontal direction, and only allowing it to move horizontally, thereby ensuring the stability of the entire transmission system and providing a strong guarantee for the moving cylinder to drive the arc-shaped limiting plate to accurately limit the stator lamination.

[0015] Furthermore, support rods are provided at the four corners of the top of the machine body, and a top plate is fixedly connected to the top of each of the four support rods.

[0016] By adopting the above technical solution, the top plate, which is fixedly connected to the top of the four support rods, together with the machine body, forms a stable frame structure. The top plate can withstand the equipment from above. During the operation of the device, the support rods evenly distribute the weight of the top plate and the force it bears to the machine body, ensuring the stability of the entire device during operation and ensuring that each component can work together in a stable environment, thereby achieving precise stacking of stator laminations.

[0017] Furthermore, a cylinder is installed at the top of the top plate, and the output end of the cylinder passes through the top plate and is fixedly connected to a mounting plate.

[0018] By adopting the above technical solution, the cylinder installed at the top of the top plate is the key actuator for realizing the stacking action of stator laminations. When the stator laminations need to be stacked, the cylinder starts to work, and the piston inside it generates linear motion under the action of air pressure. The output end of the cylinder extends out accordingly. Since the output end passes through the top plate and is fixedly connected to the mounting plate, the output end will drive the mounting plate to move downward.

[0019] Furthermore, the four support rods pass through the four corners of the mounting plate, and the mounting plate and the support rods are slidably connected. A stacking assembly is provided at the bottom of the mounting plate.

[0020] By adopting the above technical solution, the mounting plate and the support rod are slidably connected. The support rod provides a stable guiding role for the up and down movement of the mounting plate, ensuring that the mounting plate remains stable during the descent and will not deviate or shake.

[0021] A stacking assembly is installed at the bottom of the mounting plate. When the mounting plate descends above the stator laminations, the stacking assembly starts to work. The stator laminations below have already undergone pre-treatment such as precise positioning by the limiting mechanism and cleaning assisted by the air blowing assembly. Driven by the mounting plate, the stacking assembly applies pressure to the stator laminations to achieve the purpose of tightly stacking multiple layers of stator laminations together. When stacking is not needed, the output end of the cylinder can retract, driving the mounting plate to move upward along the support rod, making room for other operation processes of the device, and ensuring that the entire stacking device can complete the stator lamination stacking work efficiently and orderly.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) This utility model discloses a motor stator lamination stacking device. Through a unique limiting mechanism design, the device starts the first motor, and its output shaft drives the first bevel gear to rotate, thereby causing the four first rotating rods to rotate in a circular array. Since the first rotating rods and the moving cylinder are threaded together, the moving cylinder can move along the axial direction of the first rotating rods, causing the arc-shaped limiting plate to move closer to or away from the stator laminations, thereby achieving precise limiting of stator laminations of different specifications. At the same time, the limiting device on the outer wall of the cylindrical cylinder ensures the moving direction of the moving cylinder, ensuring the accuracy of the limiting action, and greatly improving the quality and stability of stator lamination stacking.

[0024] (2) The present invention provides a motor stator lamination stacking device. When the second motor is started, the fan blades are driven to rotate through the transmission of the gear plate, driven gear, second rotating rod and third bevel gear and bevel gear ring to generate airflow, which blows air to clean the stator laminations. Multiple air blowing components are arranged around the limiting mechanism, which can blow air to the stator laminations from different directions. Compared with the traditional single-direction cleaning method, it ensures a better air blowing effect, effectively removes impurities from the surface of the stator laminations, and improves the production quality of motor stators.

Detailed Implementation

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] To prevent lamination displacement and impurity inclusions from affecting the quality and performance of the motor stator during the stator lamination process, and thus improve the quality and performance of the motor stator, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a motor stator lamination stacking device includes a body 1. A limiting mechanism 2 is provided at the top of the body 1. The limiting mechanism 2 includes a base 3. A cylindrical tube 4 is disposed inside the base 3. A first motor 5 is fixedly installed at the bottom of the inner cavity of the cylindrical tube 4. A first bevel gear 6 is fixedly connected to the output shaft of the first motor 5. Four first rotating rods 7 are arranged in a circular array rotatably through the outer wall of the cylindrical tube 4. Each of the four first rotating rods 7 is located at one end of the inner cavity of the cylindrical tube 4 and is meshed with a first bevel gear 6. Two bevel gears 8, four first rotating rods 7 with movable cylinders 9 movably disposed at their other ends, the rod body of the other end of the first rotating rod 7 is located in the inner cavity of the movable cylinder 9, and the side wall of the first rotating rod 7 located outside the inner cavity of the movable cylinder 9 is provided with external thread 21, the inner cavity of the movable cylinder 9 is provided with internal thread 22 that is screwed to the external thread 21, the end of the movable cylinder 9 away from the first rotating rod 7 passes through the base 3 and is provided with an arc-shaped limiting plate 10 for limiting the stator lamination, and the outer wall of the cylindrical cylinder 4 is provided with a limiting device to limit the movement direction of the movable cylinder 9;

[0033] The top of the body 1 is provided with a plurality of air blowing components 11, and the limiting mechanism 2 is located between the air blowing components 11. The bottom of the body 1 is provided with a drive component for driving the air blowing components 11. The drive component includes a bracket 15 fixedly connected to the inner wall of the top of the body 1. A second motor 16 is fixedly installed on the outer wall of the bottom end of the bracket 15. The output shaft of the second motor 16 passes through the bracket 15 and is fixedly connected to a gear disk 17. A plurality of driven gears 18 are rotatably connected to the inner wall of the bottom end of the bracket 15. The plurality of driven gears 18 mesh with the gear disk 17. The top of the plurality of driven gears 18 is fixedly connected to a second rotating rod 19. The top of the plurality of second rotating rods 19 passes through the body 1 and is fixedly connected to a third bevel gear 20. The air blowing component 11 includes a support plate 12 fixedly connected to the top of the body 1. A bevel gear ring 13 is rotatably connected to the side of the support plate 12. The peripheral side of the third bevel gear 20 meshes with the bevel gear ring 13. A fan blade 14 is fixedly connected to the inner wall of the bevel gear ring 13.

[0034] When in use, the first motor 5 is turned on, and the output shaft of the first motor 5 rotates, driving the first bevel gear 6 to rotate. Because the first bevel gear 6 meshes with the four second bevel gears 8, the four first rotating rods 7 rotate in a ring array on the outer wall of the cylindrical tube 4. The end of the first rotating rod 7 with the external thread 21 cooperates with the moving tube 9 through the internal thread 22 and the external thread 21. When the first rotating rod 7 rotates, the moving tube 9 will move along the axial direction of the first rotating rod 7. The moving tube 9 drives the arc-shaped limiting plate 10 to approach or move away from the stator lamination, thereby achieving the limiting operation of the stator lamination. At the same time, the limiting device set on the outer wall of the cylindrical tube 4 can ensure that the moving tube 9 only moves along a specific direction, ensuring that the limiting action is accurate.

[0035] The second motor 16 is started, and its output shaft drives the gear disk 17 to rotate. The gear disk 17 meshes with multiple driven gears 18, causing the multiple driven gears 18 to rotate, which in turn drives the second rotating rod 19 connected to them to rotate. The third bevel gear 20 at the top of the second rotating rod 19 meshes with the bevel gear ring 13, driving the bevel gear ring 13 to rotate. Since the fan blade 14 is fixed to the inner wall of the bevel gear ring 13, the rotation of the bevel gear ring 13 will drive the fan blade 14 to rotate, generating airflow to blow air onto the stator laminations, which can be used to clean the laminations. Multiple air blowing components 11 are arranged around the limiting mechanism 2, which can blow air onto the stator laminations from different directions to ensure good air blowing effect.

[0036] For example, such as Figure 2 , Figure 3 As shown, the present invention also includes a limiting device comprising a limiting frame 23 located on the upper part of the outer side wall of the cylindrical tube 4, wherein a strip-shaped limiting opening 24 is provided on the limiting frame 23.

[0037] When in use, the limiting frame 23 is fixed on the upper part of the outer wall of the cylindrical tube 4 and is the supporting structure of the entire limiting device. The strip-shaped limiting port 24 opened on it is the key to restricting the movement of the cylindrical tube 4.

[0038] For example, such as Figure 2 , Figure 3 As shown, the present invention also includes a limiting block 25 protruding from the top edge of the cylindrical tube 4. The limiting block 25 is inserted into the strip-shaped limiting port 24 and the left and right outer walls of the limiting block 25 slide against the left and right inner walls of the strip-shaped limiting port 24 respectively.

[0039] In use, when the first motor 5 drives the first rotating rod 7 to rotate, causing the moving cylinder 9 to move, the limiting block 25 is inserted into the strip-shaped limiting port 24, and its left and right outer walls are tightly slidably attached to the left and right inner walls of the strip-shaped limiting port 24. This structural design is like putting a "shackle" on the movement of the cylindrical cylinder 4. It prevents the cylindrical cylinder 4 from shifting and rotating arbitrarily in the horizontal direction, and only allows it to move horizontally, thereby ensuring the stability of the entire transmission system and providing a strong guarantee for the moving cylinder 9 to drive the arc-shaped limiting plate 10 to accurately limit the stator lamination.

[0040] For example, such as Figure 1 As shown, the present invention also includes a support rod 26 at each of the four corners of the top of the body 1, and a top plate 27 is fixedly connected to the top of each of the four support rods 26.

[0041] During use, the top plate 27, which is fixedly connected to the top of the four support rods 26, together with the machine body 1, forms a stable frame structure. The top plate 27 can withstand the equipment from above. During the operation of the device, the support rods 26 evenly distribute the weight of the top plate 27 and the force it bears to the machine body 1, ensuring the stability of the entire device during operation and ensuring that each component can work together in a stable environment, thereby achieving precise stacking of stator laminations.

[0042] For example, such as Figure 1 As shown, the present invention also includes a cylinder 28 installed at the top of the top plate 27, and the output end of the cylinder 28 passes through the top plate 27 and is fixedly connected to an mounting plate 29.

[0043] In use, the cylinder 28 installed at the top of the top plate 27 is the key actuator for stacking stator laminations. When it is necessary to stack stator laminations, the cylinder 28 starts to work, and the piston inside it moves linearly under the action of air pressure. The output end of the cylinder 28 extends out accordingly. Since the output end passes through the top plate 27 and is fixedly connected to the mounting plate 29, the output end will drive the mounting plate 29 to move downward.

[0044] For example, such as Figure 1As shown, the present invention also includes four support rods 26 that pass through the four corners of the mounting plate 29 respectively, and the mounting plate 29 and the support rods 26 are slidably connected. The bottom end of the mounting plate 29 is provided with a stacking assembly.

[0045] During use, the mounting plate 29 is slidably connected to the support rod 26. The support rod 26 provides a stable guide for the up and down movement of the mounting plate 29, ensuring that the mounting plate 29 remains stable during descent and does not deviate or sway.

[0046] A stacking assembly is provided at the bottom of the mounting plate 29. When the mounting plate 29 descends above the stator laminations, the stacking assembly starts to work. The stator laminations below have been pre-treated by the limiting mechanism 2 for precise positioning and the air blowing assembly 11 for auxiliary cleaning. Driven by the mounting plate 29, the stacking assembly applies pressure to the stator laminations to achieve the purpose of tightly stacking multiple layers of stator laminations together. When stacking is not required, the output end of the cylinder 28 can be retracted, driving the mounting plate 29 to move upward along the support rod 26, making room for other operation processes of the device, and ensuring that the entire stacking device can complete the stator lamination stacking work efficiently and orderly.

[0047] It should be noted that this utility model is a motor stator lamination stacking device. When the first motor 5 is turned on, the output shaft of the first motor drives the first bevel gear 6 to rotate. Through meshing with the second bevel gear 8, the four first rotating rods 7 rotate in a circular array on the outer wall of the cylindrical tube 4. The first rotating rods 7 drive the moving tube 9 to move axially through threaded engagement. The moving tube 9 drives the arc-shaped limiting plate 10 to approach or move away from the stator lamination to complete the limiting operation. The strip-shaped limiting port 24 on the limiting frame 23 cooperates with the limiting block 25 at the top of the cylindrical tube 4 to limit the horizontal offset and rotation of the cylindrical tube 4, ensuring the accuracy of the limiting action.

[0048] The second motor 16 is started, and its output shaft drives the gear disk 17 to rotate. The gear disk 17 meshes with the driven gear 18, which drives the second rotating rod 19 to rotate. The third bevel gear 20 meshes with the bevel gear ring 13, which drives the bevel gear ring 13 to rotate, thereby causing the fan blade 14 to rotate and generate airflow. Multiple air blowing components 11 blow air onto the stator laminations from different directions to complete the cleaning.

[0049] When the cylinder 28 is activated, the cylinder output end extends and drives the mounting plate 29 to move downward along the support rod 26. The stacking assembly at the bottom of the mounting plate 29 applies pressure to the stator laminations that have undergone limiting and cleaning pretreatment, and tightly stacks the multiple layers of stator laminations together.

[0050] After lamination is completed, the output end of cylinder 28 retracts, driving the mounting plate 29 to move upward along the support rod 26, making room for subsequent operations, and shutting down the first motor 5, the second motor 16 and cylinder 28, thus completing the entire stator lamination lamination process.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
