Description

Technical Field

[0001] This invention relates to the field of motor manufacturing technology, and in particular to a device for stacking iron cores for motors used in new energy vehicles. Background Technology

[0002] The electric motor is one of the core components of new energy vehicles. Its performance directly determines the power, economy and reliability of the whole vehicle. The iron core is the main component of the motor's magnetic circuit. Its stacking quality not only affects the electromagnetic performance of the motor, but also has a significant impact on the motor's vibration, noise and loss performance.

[0003] Currently, when stacking motor cores, a positioning structure is usually used to fix the motor cores first. The positioning structure mostly consists of two or more vertical rods. Positioning is achieved by the vertical rods engaging with notches on the motor cores. However, because the length of the vertical rods is fixed, while the thickness and diameter of the motor cores to be stacked are different, it is necessary to replace the corresponding pressing plate when stacking motor cores of different sizes to avoid collision between the pressing plate and the vertical rods. This results in poor adaptability during stacking, and it is difficult to accurately control the stacking thickness of the cores, which affects product performance. Summary of the Invention

[0004] This invention provides a motor core stacking device for new energy vehicles. It does not require replacing the pressing plate during stacking. When the pressing plate moves down, it can push the positioning rod to move down synchronously, which is convenient for stacking motor cores of different sizes, improves the adaptability during stacking, and can control the stacking thickness of the core according to different needs during stacking to ensure product performance.

[0005] In a first aspect, the present invention provides a stacking device for motor cores of new energy vehicles, specifically comprising: a base; two hydraulic cylinders mounted on the top of the base, and a stacking support plate fixed on the top of the two hydraulic cylinders; two support blocks slidably mounted on the stacking support plate, a positioning rod slidably mounted in the middle of each support block, and a spring provided on the outer side of the lower part of each positioning rod; a dual-axis motor mounted on the bottom middle position of the stacking support plate via a bracket, a rotating cylinder fixed at both ends of the main shaft of the dual-axis motor, and a first lead screw slidably mounted on one side of each rotating cylinder; two support plates welded to the left and right sides of the top of the base, and a pressing plate welded to the top of the two support plates; a pressing thickness positioning plate slidably mounted on the rear side of the pressing plate, and a second lead screw threadedly mounted on the rear side of the pressing plate.

[0006] The support block has a through hole in the middle, and the positioning rod can slide up and down in the hole. The outer side of the positioning rod is also provided with a circular protrusion plate, and the top of the spring on the outer side of the positioning rod is in close contact with the bottom surface of the circular protrusion plate.

[0007] The support block has a rectangular plate at its bottom with a circular hole in the middle. Below the positioning rod is a thin circular rod that can slide up and down in the circular hole on the rectangular plate at the bottom of the support block.

[0008] The stacking tray has two vertically penetrating rectangular slots, and the support block can slide left and right in the rectangular slots. A semi-cylindrical protrusion is provided on the front and rear outer walls of the support block, and a corresponding semi-cylindrical guide groove is provided on the front and rear sides of the rectangular slots on the stacking tray.

[0009] The pressing thickness positioning plate is an L-shaped plate, and a rectangular hole corresponding to the cross-sectional size of the vertical plate of the pressing thickness positioning plate is provided on the rectangular plate on the rear side of the pressing plate. The bottom end of the second lead screw is rotatably connected to the top of the horizontal plate below the pressing thickness positioning plate.

[0010] The stacked tray has two protrusions at its bottom, and two first lead screws are respectively engaged with the threaded holes in the middle of the two protrusions. One end of the first lead screw is also rotatably connected to one side of the support block, and the threads on the outer sides of the two first lead screws are reverse threads.

[0011] The outer rear wall of the pressing thickness positioning plate is provided with height scale lines, and the starting line of the scale lines is the bottom surface of the pressing thickness positioning plate. The top of the base is also provided with four round rods, and the four round rods are slidably engaged with four round holes on the stacking tray.

[0012] The inner diameter of the cylindrical groove on the inner side of the rotating cylinder is equal to the outer diameter of the first lead screw. Two semi-cylindrical protrusions are provided on the outer wall of one end of the first lead screw, and two corresponding semi-cylindrical guide grooves are also provided on the inner wall of the rotating cylinder.

[0013] This invention provides a motor core stacking device for new energy vehicles, which has the following beneficial effects:

[0014] The positioning rod in this invention can be positioned by engaging with the notch on the motor core. The positioning rod can slide left and right with the support of the support block, thereby adjusting the distance between the two positioning rods. Therefore, the positioning rod can position motor cores of different diameters. Moreover, the positioning rod can slide up and down in the middle of the support block, so there is no need to replace the pressing plate during stacking. When the pressing plate moves down, it can push the positioning rod down synchronously, which is convenient for stacking motor cores of different sizes and improves the adaptability during stacking.

[0015] In addition, during use, the second lead screw can be rotated to drive the pressing thickness positioning plate to slide up and down in the rectangular hole on the rectangular plate on the back of the pressing plate. The plate can be adjusted to the required stacking thickness by coordinating with the scale lines on the back of the pressing thickness positioning plate. During the stacking process, the bottom surface of the pressing thickness positioning plate will be in close contact with the top surface of the stacking tray, which will meet the required stacking thickness. The pressing thickness positioning plate can also play a limiting role to prevent the stacking tray from moving upward. During stacking, the stacking thickness of the iron core can be controlled according to different requirements to ensure product performance. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. Based on the described 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.

[0030] Example 1: Please refer to Figures 1 to 8 :

[0031] This invention proposes a motor core stacking device for new energy vehicles, comprising: a base 1; two hydraulic cylinders 2 are mounted on the top of the base 1, and a stacking support plate 3 is fixed on the top of the two hydraulic cylinders 2. The base 1 supports the upper part of the device structure. When the hydraulic cylinders 2 extend and retract, they can adjust the height of the stacking support plate 3. The stacking support plate 3 supports the motor cores to be stacked; two support blocks 4 are slidably mounted on the stacking support plate 3, and a positioning rod 5 is slidably mounted in the middle of each support block 4. A spring 6 is provided on the outer side of the lower part of each positioning rod 5. The support blocks 4 are used to slide and support the positioning rod 5. The upper part of the positioning rod 5 is embedded in the notch on the motor core to position the motor core. After stacking... After completion, the hydraulic cylinder 2 can be controlled to retract, causing the stacking pallet 3 to slide back down to the bottom. At this time, the spring 6 on the outside of the positioning rod 5 will push the positioning rod 5 to slide up to the top through the circular protrusion on the outside of the positioning rod 5, thereby causing the positioning rod 5 to automatically return to its original position. A dual-axis motor 7 is installed at the bottom center of the stacking pallet 3 via a bracket. A rotating cylinder 8 is fixed at both ends of the main shaft of the dual-axis motor 7. A first lead screw 9 is slidably installed on one side of each rotating cylinder 8. The dual-axis motor 7 is used to drive the rotating cylinder 8 to rotate. The rotating cylinder 8 is used to support one end of the first lead screw 9. When the rotating cylinder 8 rotates, it can also drive the first lead screw 9 to rotate synchronously. When the first lead screw 9 rotates, it will move left and right in the threaded hole in the middle of the protrusion at the bottom of the stacking pallet 3. One end of the lead screw 9 also slides left and right in the cylindrical groove inside the rotating cylinder 8, thus driving the two support blocks 4 to slide synchronously in opposite directions in the rectangular opening groove on the stacking tray 3. This allows adjustment of the distance between the two positioning rods 5, facilitating the positioning of motor cores of different sizes. Two support plates 10 are welded to the top left and right sides of the base 1, and a pressing plate 11 is welded to the top of the two support plates 10. The support plates 10 support the pressing plate 11. During the upward movement of the stacking tray 3, the motor core moves upward synchronously. At this time, the top surface of the motor core will be in close contact with the bottom surface of the pressing plate 11, thus enabling the pressing plate 11 and the stacking tray 3 to cooperate in stacking the motor core. A piece of metal is slidably installed on the rear side of the pressing plate 11. The pressing thickness positioning plate 12 and the pressing plate 11 are respectively connected by a threaded second lead screw 13. After the motor core is placed, it can be rotated by the handwheel at the top of the second lead screw 13. When the second lead screw 13 rotates, it will move up and down in the threaded hole on the rectangular plate on the rear side of the pressing plate 11. Therefore, it can drive the pressing thickness positioning plate 12 to slide up and down in the rectangular hole on the rear side of the pressing plate 11. It can be adjusted to the required stacking thickness in conjunction with the scale line on the rear side of the pressing thickness positioning plate 12. During the stacking process, the bottom surface of the pressing thickness positioning plate 12 will be in close contact with the top surface of the stacking tray 3. At this time, the required stacking thickness will be met. Moreover, the pressing thickness positioning plate 12 can also play a limiting role to prevent the stacking tray 3 from moving up further.

[0032] In this embodiment, as Figure 8 As shown, the support block 4 has a through hole in the middle, and the positioning rod 5 can slide up and down in the hole in the middle of the support block 4. The outer side of the positioning rod 5 is also provided with a circular protrusion plate, and the top of the spring 6 on the outer side of the positioning rod 5 is in close contact with the bottom surface of the circular protrusion plate. When the bottom surface of the pressing plate 11 is in close contact with the top of the positioning rod 5, it will push the positioning rod 5 to slide down in the hole in the middle of the support block 4, ensuring that the pressing plate 11 can stack motor cores of different thicknesses. After the stacking is completed, the hydraulic cylinder 2 can be controlled to retract and drive the stacking support plate 3 to slide down to the bottom again. At this time, the spring 6 on the outer side of the positioning rod 5 will push the positioning rod 5 to slide up to the top through the circular protrusion plate on the outer side of the positioning rod 5, so that the positioning rod 5 will automatically return to its position.

[0033] In this embodiment, as Figure 6 and Figure 8 As shown, a rectangular plate is provided at the bottom of the support block 4, and a circular hole is provided in the middle of the rectangular plate. Below the positioning rod 5 is a thin circular rod, and the thin circular rod below the positioning rod 5 can slide up and down in the circular hole on the rectangular plate at the bottom of the support block 4. When the positioning rod 5 slides up and down in the circular hole in the middle of the support block 4, the thin circular rod below it will also slide up and down in the circular hole on the rectangular plate at the bottom of the support block 4, thereby ensuring the stability of the positioning rod 5 when it slides up and down.

[0034] In this embodiment, as Figures 1-6 and Figure 8 As shown, the stacking tray 3 has two vertically penetrating rectangular slots. The support block 4 can slide left and right in the rectangular slots. The front and rear outer walls of the support block 4 are each provided with a semi-cylindrical protrusion. The front and rear sides of the rectangular slots on the stacking tray 3 are each provided with a corresponding semi-cylindrical guide groove. When the first lead screw 9 rotates, it can drive the support block 4 to slide left and right in the rectangular slots on the stacking tray 3. When the support block 4 slides left and right, the semi-cylindrical protrusions on its front and rear sides will slide left and right in the semi-cylindrical guide grooves on the inner walls of the rectangular slots on the stacking tray 3, thereby ensuring the stability of the support block 4 when sliding.

[0035] In this embodiment, as Figures 1-3As shown, the pressing thickness positioning plate 12 is an L-shaped plate. A rectangular hole corresponding to the cross-sectional size of the vertical plate of the pressing thickness positioning plate 12 is provided on the rectangular plate on the rear side of the pressing plate 11. The bottom end of the second lead screw 13 is rotatably connected to the top of the horizontal plate below the pressing thickness positioning plate 12. After the motor core is placed, it can be rotated by the handwheel at the top of the second lead screw 13. When the second lead screw 13 rotates, it will move up and down in the threaded hole on the rectangular plate on the rear side of the pressing plate 11. Therefore, it can drive the pressing thickness positioning plate 12 to slide up and down in the rectangular hole on the rectangular plate on the rear side of the pressing plate 11. It can also be adjusted to the required stacking thickness in conjunction with the scale line on the rear side of the pressing thickness positioning plate 12. During the stacking process, the bottom surface of the pressing thickness positioning plate 12 will be in close contact with the top surface of the stacking tray 3. At this time, the required stacking thickness will be met. Moreover, the pressing thickness positioning plate 12 can also play a limiting role to prevent the stacking tray 3 from moving up further.

[0036] In this embodiment, as Figure 6 As shown, the bottom of the stacking tray 3 is provided with two protrusions. Two first lead screws 9 are respectively engaged with the threaded holes in the middle of the two protrusions. One end of the first lead screw 9 is also rotatably connected to one side of the support block 4. Moreover, the threads on the outer sides of the two first lead screws 9 are reverse threads. When the first lead screw 9 rotates, it will move left and right in the threaded hole in the middle of the protrusion at the bottom of the stacking tray 3. At the same time, one end of the first lead screw 9 will also slide left and right in the cylindrical groove inside the rotating cylinder 8. Therefore, it can drive the two support blocks 4 to slide synchronously in opposite directions in the rectangular opening groove on the stacking tray 3, thereby adjusting the distance between the two positioning rods 5, which is convenient for positioning motor cores of different sizes.

[0037] In this embodiment, as Figure 7 As shown, the inner diameter of the cylindrical groove on the inner side of the rotating cylinder 8 is equal to the outer diameter of the first lead screw 9. Two semi-cylindrical protrusions are provided on the outer wall of one end of the first lead screw 9, and two corresponding semi-cylindrical guide grooves are also provided on the inner wall of the rotating cylinder 8. When the rotating cylinder 8 rotates, it will rely on the semi-cylindrical guide groove on its inner wall and the semi-cylindrical protrusion on the outer wall of one end of the first lead screw 9 to drive the first lead screw 9 to rotate synchronously. When the first lead screw 9 rotates, it will move left and right in the threaded hole in the middle of the protrusion at the bottom of the stacking support plate 3. At the same time, one end of the first lead screw 9 will also slide left and right in the cylindrical groove on the inner side of the rotating cylinder 8, ensuring that the first lead screw 9 and the support block 4 can move left and right normally.

[0038] Example 2, based on Example 1, such as Figures 1-8As shown, the outer rear wall of the pressing thickness positioning plate 12 is provided with height scale lines, and the starting line of the scale lines is the bottom surface of the pressing thickness positioning plate 12. The top of the base 1 is also provided with four round rods, and the four round rods slide in cooperation with the four round holes on the stacking tray 3. When the second lead screw 13 rotates, it will move up and down in the threaded hole on the rectangular plate on the rear side of the pressing plate 11, so that the pressing thickness positioning plate 12 can slide up and down in the rectangular hole on the rectangular plate on the rear side of the pressing plate 11, and adjust to the required stacking thickness in cooperation with the scale lines on the rear side of the pressing thickness positioning plate 12, so as to meet different stacking thickness requirements. The round rods on the top of the base 1 cooperate with the round holes on the stacking tray 3 to ensure the stability of the stacking tray 3 when sliding up and down.

[0039] The working principle of this embodiment is as follows: During installation, the device can be fixed on the processing table by the base 1, and the hydraulic cylinder 2 is connected to the external hydraulic oil pump and controller. The dual-axis motor 7 is connected to the external controller and power supply. When it is necessary to use this device to stack the motor core, first place the motor core to be stacked in the top middle position of the stacking tray 3, and make two notches on the motor core located on the left and right sides respectively. Then, the dual-axis motor 7 can be controlled by the external controller to drive the two rotating cylinders 8 to rotate. When the rotating cylinder 8 rotates, it will rely on the semi-cylindrical guide groove on its inner wall to cooperate with the semi-cylindrical protrusion on the outer wall of one end of the first lead screw 9 to drive the first lead screw 9 to rotate synchronously. When the first lead screw 9 rotates, it will... The support block 4 moves left and right in the threaded hole in the middle of the protrusion at the bottom of the stacking tray 3. At the same time, one end of the first lead screw 9 slides left and right in the cylindrical groove inside the rotating cylinder 8. Therefore, it can drive the support block 4 to slide left and right in the rectangular opening groove on the stacking tray 3. When the support block 4 slides left and right, the semi-cylindrical protrusions on its front and rear sides will slide left and right in the semi-cylindrical guide grooves on the inner walls of the rectangular opening groove on the stacking tray 3, thus ensuring the stability of the support block 4 when sliding. Moreover, after the support block 4 slides left and right, the distance between the two positioning rods 5 can be adjusted, so that the upper part of the positioning rod 5 can be embedded into the notch on the motor core to position the motor core. It can also position motor cores of different sizes. After placement, the second lead screw 13 can be rotated by the handwheel at its top. When the second lead screw 13 rotates, it will move up and down in the threaded hole on the rectangular plate behind the pressing plate 11. This will cause the pressing thickness positioning plate 12 to slide up and down in the rectangular hole on the rectangular plate behind the pressing plate 11. The plate will be adjusted to the required stacking thickness according to the scale line on the back of the pressing thickness positioning plate 12. Then, the controller will control the two hydraulic cylinders 2 to extend and push the stacking tray 3 upward. During the upward movement of the stacking tray 3, the motor core will move upward synchronously. At the same time, the bottom surface of the pressing plate 11 on the top of the support plate 10 will first be in close contact with the top of the positioning rod 5. Then, the pressing plate 11 will push the positioning rod 5 downward in the round hole in the middle of the support block 4. The motor core moves, and the top surface of the motor core will be in close contact with the bottom surface of the pressing plate 11. Therefore, the pressing plate 11 and the stacking support plate 3 can cooperate to stack the motor core. During the stacking process, the bottom surface of the pressing thickness positioning plate 12 will be in close contact with the top surface of the stacking support plate 3. At this time, the required stacking thickness will be met. The pressing thickness positioning plate 12 can also play a limiting role to prevent the stacking support plate 3 from moving upward. After the stacking is completed, the hydraulic cylinder 2 can be controlled to retract and drive the stacking support plate 3 to slide down to the bottom again. At this time, the spring 6 on the outside of the positioning rod 5 will push the positioning rod 5 to slide up to the top through the circular protrusion on the outside of the positioning rod 5, so that the positioning rod 5 will automatically return to its position. Finally, the stacked motor core can be removed.
