Description

Technical Field

[0001] This utility model relates to the field of rotor assembly technology, and in particular to rotor magnet sheath assembly tooling. Background Technology

[0002] Rotor magnet sleeves are components used to protect the permanent magnets (i.e., magnets) on the rotor of a motor or generator. In motor design, especially in high-performance permanent magnet synchronous motors or brushless DC motors, the rotor typically contains strong permanent magnet materials, which are crucial for the motor's operation. Traditional rotor magnet sleeve assembly usually involves applying adhesive to the magnets, then fitting the magnet sleeve over them, and allowing it to pre-cure for a period before removal. However, current methods result in small gaps between the magnet sleeve and the magnet, thin magnet sleeves, and significant deformation, making it difficult to fit them onto the rotor magnet surface. This assembly is challenging and severely impacts efficiency. Furthermore, limited operating space during installation leads to excessive adhesive overflow, increasing the difficulty of cleaning. Additionally, the small bonding area between the magnet sleeve and the magnet results in low reliability.

[0003] Therefore, it is necessary to design a rotor magnet sheath assembly tooling that can quickly compress the magnet sheath to assemble the rotor magnet sheath and can be directly reused after assembly, increasing the bonding area, reducing glue overflow, preventing magnet sheath displacement, improving assembly efficiency, and being easy to use. Utility Model Content

[0004] To overcome the shortcomings of current methods, such as the difficulty in assembling the magnet sheath and magnet, which seriously affects assembly efficiency, and the large amount of adhesive overflow during the assembly of the magnet sheath due to limited operating space, increasing the difficulty of cleaning the adhesive, as well as the small bonding area between the magnet sheath and the magnet and low reliability, this utility model provides a rotor magnet sheath assembly tooling that can quickly compress the magnet sheath to assemble the rotor magnet sheath and can be directly reused after assembly, increasing the bonding area, reducing adhesive overflow, preventing the displacement of the magnet sheath, improving assembly efficiency, and being easy to use.

[0005] The technical solution is as follows: the rotor magnet sheath assembly tooling includes a mounting base plate, a rotor positioning seat, magnets, a drive assembly and a pressing assembly. The upper side of the middle of the mounting base plate is connected to the rotor positioning seat, and multiple magnets are connected to the rotor positioning seat. The lower side of the mounting base plate is provided with a drive assembly, and the upper side of the mounting base plate is provided with a pressing assembly for pressing the rotor magnet sheath.

[0006] As a further preferred option, the mounting base plate has multiple grooves.

[0007] As a further preferred embodiment, the drive assembly includes connecting pins, a reducer, and a motor. Multiple connecting pins are connected to the lower side of the mounting base plate, and a reducer is connected between the lower parts of the connecting pins. The motor is connected to the reducer.

[0008] As a further preferred embodiment, the press assembly includes a turntable, slide rails, sliders, connecting blocks, positioning pins, and press heads. The turntable is connected to the output shaft of the motor. The positioning pins are all slidably connected to the turntable. The turntable contacts the mounting base plate. Multiple slide rails are connected to the upper side of the mounting base plate. Sliders are slidably connected to the slide rails. Connecting blocks are connected to the upper side of the sliders. Positioning pins are connected to the connecting blocks. The positioning pins are all slidably connected to the mounting base plate. The positioning pins are all movablely connected to the turntable. Press heads are connected to the upper side of the connecting blocks.

[0009] As a further preferred option, the locating pins are evenly distributed along the turntable.

[0010] As a further preferred option, the pressure head is made of cemented carbide.

[0011] The beneficial effects of this utility model are: by rotating the turntable, the positioning pin, connecting block and slider move, so that the pressure head moves and contacts the magnetic steel sleeve to squeeze it, so that the magnetic steel sleeve fits. After assembly, the rotor can be directly removed. This allows for quick squeezing of the magnetic steel sleeve to assemble the rotor magnetic steel sleeve, and it can be directly reused after assembly. It increases the bonding area, reduces glue overflow, prevents the magnetic steel sleeve from shifting, improves assembly efficiency and is convenient to use. Attached Figure Description

[0019] Rotor magnet sheath fittings and tooling, such as Figures 1-5 As shown, it includes a mounting base plate 1, a rotor positioning seat 2, magnets 3, a drive assembly, and a pressing assembly. The mounting base plate 1 has eight sliding grooves for easy movement. The rotor positioning seat 2 is connected to the upper side of the middle part of the mounting base plate 1. The eight magnets 3 are connected to the rotor positioning seat 2. The drive assembly is provided on the lower side of the mounting base plate 1, and the pressing assembly for pressing the sheath of the magnets 3 on the upper side of the mounting base plate 1 is provided.

[0020] like Figure 1 , Figure 4 and Figure 5 As shown, the drive assembly includes connecting pins 4, a reducer 5, and a motor 6. Four connecting pins 4 are connected to the lower side of the mounting base plate 1. The reducer 5 is connected between the lower parts of the connecting pins 4, and the motor 6 is connected to the reducer 5.

[0021] like Figure 1 , Figure 2 and Figure 4 As shown, the press assembly includes a turntable 7, slide rails 8, sliders 9, connecting blocks 10, positioning pins 11, and press heads 12. The turntable 7 is connected to the output shaft of the motor 6. The positioning pins 11 are all slidably connected to the turntable 7. The turntable 7 is in contact with the mounting base plate 1. Eight slide rails 8 are connected to the upper side of the mounting base plate 1. Sliding sliders 9 are slidably connected to each slide rail 8. Connecting blocks 10 are connected to the upper side of each slider 9. Positioning pins 11 are connected to each connecting block 10. The positioning pins 11 are all slidably connected to the mounting base plate 1. The positioning pins 11 are all movably connected to the turntable 7. The positioning pins 11 are evenly distributed along the turntable 7. The press heads 12 are connected to the upper side of the connecting blocks 10. The press heads 12 are made of hard alloy material and have good hardness and wear resistance.

[0022] When it is necessary to assemble the magnet 3 sleeve on the rotor, this device can be used. Adhesive is applied to the surface of the magnet 3 using a brush. The rotor, after being coated with adhesive, is then placed in the rotor positioning seat 2. The magnet 3 on the rotor positioning seat 2 attracts the rotor, causing it to automatically find its position. Next, the magnet 3 sleeve is fitted over the outer ring of the magnet 3. Then, the motor 6 and the reducer 5 on the connecting pin 4 are started. The high-speed, low-torque output generated by the motor 6 is converted into a low-speed, high-torque output by the reducer 5, causing the turntable 7 to rotate. This causes the positioning pin 11 to move along the slide groove on the mounting base plate 1, moving the connecting block 10 and the slider 9 along the slide rail 8. This causes the pressure head 12 to move and contact the magnet 3 sleeve for compression, making the magnet 3 sleeve fit against the magnet 3 on the rotor, thereby pressing the rotor's magnets... The steel 3 sheath is assembled. The positioning pins 11 are evenly distributed along the turntable 7. The pressure head 12 is made of hard alloy, which has good hardness and wear resistance. After assembly, the motor 6 operates in reverse, causing the positioning pins 11 to move and reset in the reverse direction, causing the connecting block 10 to move and reset in the reverse direction, causing the slider 9 to move and reset in the reverse direction, and causing the pressure head 12 to move and reset in the reverse direction and disengage from the magnet 3 sheath. Then the rotor is removed, and the glue is cleaned. This allows for quick squeezing of the magnet 3 sheath to assemble the rotor and allows for direct turnover after assembly, increasing the bonding area, reducing glue overflow, preventing displacement of the magnet 3 sheath, improving assembly efficiency, and making it convenient to use. Then the above operation is repeated to apply glue, install, and assemble the magnet 3 until the rotor and magnet 3 sheath are all assembled. Then the motor 6 and the reducer 5 are turned off.
