Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic core assembly, and in particular relates to a magnetic core flipping mechanism. Background Art

[0002] The magnetic core of the motor is a key component in the motor. Its main function is to generate a magnetic field so that the motor can operate normally under the action of the electromagnetic field. When current passes through the magnetic core of the drive motor, it will generate a rotating magnetic field on the magnetic axis. This magnetic field will interact with the stator magnetic field to drive the rotor to rotate. At the same time, the magnetic core can also keep the magnetic lines of force in the magnetic circuit as much as possible when the motor is running, so as to reduce the amount of magnetic leakage in the magnetic circuit and improve the output power and efficiency of the motor. The magnetic core is mainly composed of a shell, a cylindrical magnet and a pole shoe. The assembly process of the magnetic core requires the pole shoes to be symmetrically installed at both ends of the cylindrical magnet. After the magnet is installed at one end of the cylindrical magnet, the cylindrical magnet needs to be flipped and the pole shoe needs to be installed at the other end. The existing cylindrical magnet flipping is mainly done manually, with low flipping accuracy and low efficiency. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] It should be noted that when a component is referred to as being "fixed to" or "disposed on" another component, it can be directly on the other component or indirectly on the other component. When a component is referred to as being "connected to" another component, it can be directly or indirectly connected to the other component.

[0024] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0026] The utility model provides a magnetic core flipping mechanism, such as Figure 1-7 As shown, it includes: a fixed plate 1 and a flip block 3, a circular hole 2 is provided in the fixed plate 1, a flip block 3 is provided in the circular hole 2, a through hole 4 is provided in the flip block 3, tapered grooves 5 are provided at both ends of the through hole 4, a motor 7 is provided on the side of the fixed plate 1, the output shaft of the motor 7 is connected to one end of the rotating shaft 8, and the other end of the rotating shaft 8 passes through the rectangular groove 6 on the fixed plate 1 and is connected to the flip block 3.

[0027] A pressing block 9 is arranged in the rectangular groove 6, and an axial hole 10 is arranged on the pressing block 9, through which the rotating shaft 8 passes, so that the rotating shaft 8 can be installed through the axial hole 10. Two screw holes 11 are arranged on the pressing block 9, so that the pressing block 9 can be easily disassembled and installed.

[0028] A movable plate 12 is arranged below the fixed plate 1, and a guide hole 13 is arranged at the bottom of the movable plate 12. The guide hole 13 is arranged coaxially with the through hole 4, and the guide hole 13 is slightly smaller than the through hole 4, which can prevent the cylindrical magnet and the pole shoe in the through hole 4 from falling due to gravity. External force is required to squeeze through the guide hole 13, thereby improving the stability of the magnetic core assembly. The fixed plate 1 and the movable plate 12 are arranged in parallel, and two bases 14 are arranged below the movable plate 12. Two vertical support rods 15 are arranged at intervals on the base 14, and the lower end of the support rod 15 is connected to the base 14, and the upper end of the support rod 15 is connected to the bottom end of the fixed plate 1. The support rod 15 plays a role in supporting the fixed plate 1.

[0029] A sliding column 16 is coaxially arranged on the support rod 15, and the sliding column 16 passes through the moving plate 12 and is slidably connected with the moving plate 12. A cylinder 17 is arranged on the base 14, and the cylinder 17 is located between the two support rods 15. A fixed pipe 18 is arranged at the bottom end of the moving plate 12, and the piston rod of the cylinder 17 is upwardly connected to the lower end of the fixed pipe 18. The moving plate 12 is driven up and down along the sliding column 16 by the cylinder 17. When the moving plate 12 moves downward, the flip block 3 can be flipped. When the moving plate 12 moves upward, it plays a limiting role and the flip block 3 cannot be flipped. Two mounting holes 19 are arranged on the base 14 to facilitate the installation or disassembly of the base and the workbench.

[0030] The working principle and beneficial technical effects of the above technical scheme are as follows: start the magnet feeder 20 to place the cylindrical magnet 21 above the flip block 3, and then insert it into the through hole 4 on the flip block 3. The pole shoe feeder 22 moves the pole shoe 23 to the top of the flip block 3. Then, a pole shoe 23 is pressed onto one end of the cylindrical magnet 21. Then, start the cylinder 17 to drive the movable plate 12 to move downward to make room for the flip block 3 to flip. Start the motor 7 to drive the flip block 3 to flip 180 degrees. Then, start the cylinder 17 to drive the movable plate 12 to move upward. Then, start the slide 24 to drive the core shell to move below the flip block 3. Then, use the pole shoe feeder 22 to press another pole shoe 23 onto the other end of the cylindrical magnet 21, and continue to press it downward along the guide hole 13 of the movable plate 12 into the core shell to assemble the core. Through the cooperation of the motor and the cylinder, the cylindrical magnet can be accurately flipped, and the pole shoes can be quickly installed at both ends of the cylindrical magnet to efficiently assemble the magnetic core.
