Abstract
Description
Technical Field
[0001] This utility model relates to the field of stator core production technology, and in particular to a flipping mechanism for a large stator core. Background Technology
[0002] Large stator cores require face-changing during production, which involves converting the top and bottom surfaces of the stator core. This process requires flipping the stator core up and down. However, due to the large weight of the stator core, manual flipping is quite difficult, and it is also easy to damage the stator laminations during flipping. In addition, there are some machines on the market that can flip large stator cores up and down, but these machines are relatively complex in structure and have a high cost.
[0003] Therefore, further improvements are necessary. Utility Model Content
[0004] The purpose of this invention is to provide a large stator core flipping mechanism that is simple in structure, has a good flipping effect, low cost, convenient operation, and strong practicality, so as to overcome the shortcomings of the prior art.
[0005] A large stator core flipping mechanism designed for this purpose is characterized by comprising a driving device, a rotating shaft, and a flipping plate for positioning and placing the stator core. The driving device drives and connects to the rotating shaft, and the flipping plate is fixed on the rotating shaft. The driving device drives the flipping plate to rotate up and down through the rotating shaft, so that the flipping plate drives the stator core to flip up and down.
[0006] The drive unit includes a motor and a gearbox. The output shaft of the motor is connected to the input end of the gearbox, and the output end of the gearbox is connected to a rotating shaft.
[0007] Positioning posts are provided on both sides of the flip plate. When the stator core is placed on the flip plate, the stator core is locked between the two positioning posts.
[0008] The positioning column is fitted with a flexible positioning element, and the stator core is locked between the two positioning elements.
[0009] It also includes a mounting base, on which the rotating shaft is rotatably mounted.
[0010] The mounting base is equipped with several position sensors, which are connected to the motor. When the flip plate rotates up and down to the start and end of its stroke, the corresponding position sensors are activated.
[0011] A limit block is provided on one side of the mounting base. The limit block corresponds to the positioning post. When the flip plate rotates upward to the end of the stroke, the positioning post is limited to the limit block.
[0012] It also includes an electronic control device, which contains a control circuit board that is electrically connected to the motor and the position sensor. The electronic control device is equipped with operation buttons and a display screen.
[0013] It also includes a mounting base with a protective cover, on which the motor is fixed and located inside the protective cover.
[0014] A first fixing hole is provided on the rotating shaft, and a second fixing hole is provided on the flip plate. After the fastener passes through the first fixing hole, it is fastened to the second fixing hole so that the flip plate is fixed on the rotating shaft.
[0015] The large stator core flipping mechanism of this utility model is provided with a drive device, a rotating shaft and a flipping plate. The drive device drives the flipping plate to rotate up and down through the rotating shaft, so that the flipping plate drives the stator core to flip up and down. This structure can easily flip the large stator core up and down, avoiding damage to the stator laminations when flipping the stator core. Moreover, this structure can achieve the flipping of the large stator core using only a motor, gearbox, rotating shaft and flipping plate, involving fewer parts, so the structure is relatively simple and the equipment cost is relatively low.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] See Figures 1-6 The large stator core flipping mechanism includes a drive device 1, a rotating shaft 2, and a flipping plate 3 for positioning and placing the stator core 4. The drive device 1 drives the rotating shaft 2, and the flipping plate 3 is fixed on the rotating shaft 2. The drive device 1 drives the flipping plate 3 to rotate up and down through the rotating shaft 2, so that the flipping plate 3 drives the stator core 4 to flip up and down. When the stator core 4 flips, the stator core 4 is first installed on the flipping plate 3. At this time, the stator core 4 is in a vertical setting state (e.g., ...). Figure 5(As shown), then the drive device 1 drives the flipping plate 3 to rotate upwards by 90 degrees, so that the stator core 4 flips downwards. At this time, the stator core 4 is in a flat position (as shown). Figure 6 As shown in the diagram, the stator core 4 is then lifted by a crane and rotated horizontally by 180 degrees. The stator core 4 is then reinstalled onto the flipping plate 3. The drive device 1 then drives the flipping plate 3 to rotate downwards by 90 degrees, causing the stator core 4 to flip upwards. At this point, the stator core 4 is in a vertical position, thus completing the face-changing of the stator core 4, that is, the top and bottom surfaces of the stator core 4 are switched. Initially, the top surface is facing upwards, and after the stator core 4 is flipped, the bottom surface is facing upwards.
[0022] The drive device 1 includes a motor 5 and a gearbox 6. The output shaft of the motor 5 is connected to the input end of the gearbox 6, and the output end of the gearbox 6 is connected to the rotating shaft 2. The motor 5 drives the rotating shaft 2 to rotate through the gearbox 6. The gearbox 6 can increase the output force of the motor 5, thereby enabling stable flipping of the large stator core 4. This flipping mechanism is used to flip the large stator core 4. Since the large stator core 4 is heavy, it would be quite difficult to flip it manually, so equipment is needed to flip the large stator core 4.
[0023] Positioning posts 7 are provided on both sides of the flip plate 3. When the stator core 4 is placed on the flip plate 3, the stator core 4 is locked between the two positioning posts 7, thereby fixing the stator core 4 on the flip plate 3. The stator core 4 is placed vertically on the flip plate 3.
[0024] The positioning post 7 is fitted with an elastic positioning element, and the stator core 4 is locked between the two positioning elements. The elastic positioning element can firmly lock the stator core 4 and prevent the stator core 4 from loosening. The positioning element is made of soft material.
[0025] It also includes a mounting base 8, on which the rotating shaft 2 is rotatably mounted. The mounting base 8 is located at both ends of the rotating shaft 2.
[0026] Two position sensors 9 are provided on the mounting base 8. The position sensors 9 are connected to the motor 5. When the flip plate 3 rotates up and down to the beginning and end of the stroke, it acts on the corresponding position sensor 9. After the position sensor 9 detects that the flip plate 3 has rotated to the correct position, it sends a signal to the control circuit board. The control circuit board cuts off the power to the motor 5, thereby stopping the flip plate 3 from rotating.
[0027] A limit block 10 is provided on one side of the mounting base 8. The limit block 10 corresponds one-to-one with the positioning post 7. When the flip plate 3 rotates upward to the end of the stroke, the positioning post 7 is limited on the limit block 10 to prevent the flip plate 3 from rotating excessively. When the flip plate 3 rotates downward to the beginning of the stroke, the bottom of the flip plate 3 is supported on the rotating shaft 2, which also prevents the flip plate 3 from rotating excessively.
[0028] It also includes an electric control device 11, which contains a control circuit board. The control circuit board is electrically connected to the motor 5 and the position sensor 9. The electric control device 11 is equipped with an operation button 12 and a display screen 13. When the operation button 12 is pressed, the motor 5 starts to work, thereby driving the flip plate 3 to rotate. The electric control device 11 is an electric control box.
[0029] It also includes a fixed base 14, on which a protective cover 15 is provided. The motor 5 is fixed on the fixed base 14 and is located inside the protective cover 15, which can protect the motor 5. A fixed column 18 is provided on the top of the protective cover 15, and the electronic control device 11 is fixed on the fixed column 18.
[0030] The rotating shaft 2 is provided with a first fixing hole 16, and the flip plate 3 is provided with a second fixing hole 17. The fastener (screw) passes through the first fixing hole 16 and is then fastened to the second fixing hole 17 so that the flip plate 3 is fixed on the rotating shaft 2.
[0031] It also includes a base 19, on which the gearbox 6 is fixed.
[0032] It also includes a base plate 20, a mounting base 8, a fixing base 14, a base 19, and a limiting block 10, which are respectively fixed on the base plate 20.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
