Description

Technical Field

[0001] This utility model relates to the field of stator and rotor assembly mechanism technology, and particularly to electronic stator and rotor assembly mechanism and assembly equipment. Background Technology

[0002] In the assembly of electronic stators and rotors, the magnets of surface-mount permanent magnet motors are generally glued to the shaft after the bottom surface is coated with adhesive. The original process was for workers to install them by hand. Due to the magnetic repulsion between the magnets, it is difficult to position the magnets during the installation process. Moreover, the magnetic repulsion is large, and there is a risk that the magnets will fly out. Especially for the magnets installed last in the circumferential direction, the repulsion is very large, making it very difficult to install manually, and the efficiency is also low.

[0003] For example, the patent entitled "A Rotor Magnet Installation Tool for a Surface-Modified Permanent Magnet Motor" (patent application number: CN202022221540.6) discloses a rotor magnet installation tool for a surface-mounted permanent magnet motor. This tool avoids the problem of difficult positioning of magnets due to repulsive forces between magnets during manual installation, and avoids the risk of magnets flying out due to large repulsive forces. It effectively improves safety, positioning accuracy, and magnet bonding efficiency. The structure is simple, the positioning is accurate, the fixing is firm, and the reliability and stability are high. However, the upper and lower halves of the clamp are detachably connected by bolts. If multiple magnets need to be positioned, disassembly and replacement are relatively cumbersome, and the efficiency of use needs to be improved.

[0004] Therefore, it is necessary to propose an electronic stator and rotor assembly mechanism and assembly equipment to solve the above problems. Utility Model Content

[0026] This utility model provides, for example Figures 1-4 The electronic stator and rotor assembly mechanism shown includes a fixed ring 1 with an annular groove 2 on its outer ring. To position the fixed ring 1 on the rotor shaft, a second bolt 15 is threaded to both sides of the fixed ring 1. A clamping plate 16 is rotatably connected to one end of the second bolt 15 located inside the fixed ring 1. The clamping plate 16 is V-shaped, and the side of the two clamping plates 16 that is close to each other is a recessed side. A rubber pad can be placed on the recessed side to reduce friction.

[0027] In addition, the friction between the second bolt 15 and the fixing ring 1 is appropriate, and there will be no random rotation. If necessary, a limiting structure such as a pin can be set.

[0028] In actual use, the fixing ring 1 is put onto the rotor shaft, and the second bolts 15 on both sides are rotated at the same time. The two clamps 16 move towards each other so that the fixing ring 1 is fixed on the rotor shaft. After fixing, the fixing ring 1 is ensured to be concentric with the rotor shaft.

[0029] The annular groove 2 is equipped with a rotating ring 3, and a radial plate 5 is fixedly connected to the outer ring of the rotating ring 3. The radial plate 5 rotates synchronously with the rotating ring 3.

[0030] An axial adjustment assembly is provided on the radial plate 5. The axial adjustment assembly includes a sliding channel 6 and an axial plate 7. The sliding channel 6 is opened on the end of the radial plate 5 away from the rotating ring 3. The axial plate 7 is slidably disposed inside the sliding channel 6. A positioning assembly is provided on the axial plate 7 for installing magnets.

[0031] After the fixing ring 1 is fixed on the rotor shaft, the operator can slide the axial plate 7 and rotate the radial plate 5 to flexibly adjust the position of the positioning component.

[0032] This utility model, by setting up a fixed ring 1, an axial adjustment component and other structures, can flexibly adjust the position of the positioning component, and only requires a single positioning, making the operation convenient and improving the efficiency of the electronic stator and rotor assembly mechanism.

[0033] In a specific configuration, the positioning component includes a magnetic guide frame 9, which is fixedly connected to one end of the axial plate 7. A fixed seat 10 is fixedly installed on the top of the magnetic guide frame 9. A magnetic pressure plate 13 is provided inside the magnetic guide frame 9. An electric push rod 11 is fixedly connected to the top of the fixed seat 10. A circular groove is provided on the fixed seat 10 for the extension and retraction end of the electric push rod 11 to pass through. The magnetic pressure plate 13 is fixedly connected to the extension and retraction end of the electric push rod 11.

[0034] A limiting block 8 is fixedly connected to the end of the axial plate 7 away from the magnetic guide frame 9. The length and width of the limiting block 8 are greater than the length and width of the sliding channel 6, to prevent the axial plate 7 from sliding out directly.

[0035] The magnet is placed inside the magnet guide frame 9, with the magnet pressure plate 13 positioned above it. After the positioning assembly is adjusted to the installation position, the telescopic end of the electric push rod 11 is extended, pushing the magnet pressure plate 13 to slowly descend along the magnet guide frame 9, allowing the magnet to reach the required installation position during the electronic stator and rotor assembly. Once the adhesive is applied, the magnet installation is complete, improving positioning accuracy and magnet bonding efficiency.

[0036] A viewing hole 12 is provided at the bottom of the magnetic guide frame 9 to facilitate observation of the pressing of the magnet inside the magnetic guide frame 9.

[0037] The radial plate 5 is threaded with a first bolt 14 at the end away from the rotating ring 3. The first bolt 14 cooperates with the axial plate 7. After the position of the axial plate 7 is adjusted and determined, the first bolt 14 is rotated and pressed against the axial plate 7 to position the axial plate 7.

[0038] The friction between the first bolt 14 and the radial plate 5 is appropriate, preventing arbitrary rotation.

[0039] To achieve the positioning of the rotating ring 3, multiple magnetic blocks 17 are fixedly embedded in the inner ring of the rotating ring 3, and these magnetic blocks 17 are evenly distributed around the inner ring of the rotating ring 3. An electromagnet 4 is fixedly embedded in the inner wall of the annular groove 2, and the electromagnet 4 cooperates with the magnetic blocks 17. After the rotating ring 3 is rotated and adjusted to a certain position, the electromagnet 4 is activated, and the magnetism of the electromagnet 4 and the opposite magnetic block 17 is controlled to be opposite. Under the action of repulsive force, the electromagnet 4 and the magnetic block 17 are attracted and fixed, thereby positioning the rotating ring 3.

[0040] This utility model also proposes an electronic stator and rotor assembly equipment. Using the above-mentioned electronic stator and rotor assembly mechanism, it also includes other equipment for stator assembly, including an operating table, etc.
