Technical Field

[0001] The present application relates to the technical field of motor manufacturing, and in particular to a fully automatic and efficient motor magnetizing device. Background Art

[0002] As one of the core components of modern industry, the performance of the motor depends largely on the magnetization quality of the stator and rotor. Traditional motor magnetization methods are mostly manual or semi-automatic, which is not only inefficient, but also difficult to ensure the consistency and accuracy of magnetization. With the development of automation technology, the market has put forward higher requirements on the magnetization quality and production efficiency of motors.

[0003] Under the related technology, for example, the automatic magnetizing device disclosed in the Chinese patent with publication number CN212570583U includes a frame and a magnetizer, a workbench is fixedly arranged on the top of the frame, the magnetizer is fixedly arranged on the top of the workbench, a magnetizing support block is adapted to be arranged on the top of the magnetizer, a through groove adapted to the magnetizing support block is opened on the surface of the workbench, guide rods are arranged on both sides of the bottom of the through groove, the top of the guide rod is fixedly connected to the bottom of the workbench, a moving block is movably arranged on the surface of the guide rod, the bottom end of the connecting rod is fixedly connected to the moving block, a limit switch is fixedly arranged on the surface of the moving block, a fixed block is fixedly connected to the bottom of the guide rod, the fixed block is fixedly connected to the frame, and a fixed block is fixedly arranged in the middle of the fixed block. The lower cylinder and the fixed block are also fixed with a standard block compatible with the limit switch. The output shaft of the lower cylinder passes through the standard block. A support frame is fixedly set on the top of the frame, and the upper cylinder is fixedly set on the surface of the support frame. When in use, in the initial state, the lower cylinder is in an extended state, so that the magnetizing tray is at the top of the magnetizer, and the motor to be magnetized is placed on the surface of the magnetizing tray. At this time, the upper cylinder works to push the motor downward through the pressure block, and the lower cylinder contracts cooperatively. When the limit switch on the surface of the moving block contacts the standard block on the surface of the fixed block, the electric control box receives the signal and controls the magnetizer to work, magnetizes the motor, and clamps the motor through the upper cylinder and the lower cylinder.

[0004] With respect to the above-mentioned related technologies, when the motor is placed on the surface of the magnetized de-disc, since the magnetic force distribution on the magnetized de-disc is generally uniform, the motor cannot be ensured to be in the center position on the magnetized de-disc, which may cause uneven magnetization of the motor and affect the final magnetization effect.

The clamping assembly 23 includes a plurality of clamping seats 231, and the plurality of clamping seats 231 are distributed along the circumference of the virtual circle. The central axis of the virtual circle is parallel to the first direction. A magnetizing area 232 is formed between two adjacent clamping seats 231. The virtual circle is located in the magnetizing area 232. The magnetizing area 232 is in a through state along the first direction. The clamping seat 231 is slidably connected to the lifting seat 22 along a direction perpendicular to the central axis of the virtual circle to adjust the width of the magnetizing area 232.

[0032] Reference Figure 2 and Figure 3 Due to the difference in the size of the motor rotor, in order to make the clamping seat 231 firmly clamp the motor rotation, the clamping assembly 23 also includes a first connecting seat 233 and a first elastic member 234. The first connecting seat 233 is connected to the lifting seat 22. The expansion and contraction direction of the first elastic member 234 is perpendicular to the central axis direction of the virtual circle. The first elastic member 234 is connected between the first connecting seat 233 and the lifting seat 22. In this embodiment, the first connecting seat 233 is annular, and the first elastic member 234 is a compression spring. The first elastic member 234 has a force to drive the clamping seat 231 to move away from the first connecting seat 233 under a recoverable deformation. Under the action of the first elastic member 234, the two clamping seats 231 stably clamp the motor rotor.

[0033] Reference Figure 3 Since the motor rotor is cylindrical, in order to improve the clamping effect of the clamping seat 231 on the motor rotor, the end of the clamping seat 231 away from the first connecting seat 233 is arc-shaped, and the arc opening faces the side away from the first connecting seat 233, so as to increase the contact area between the clamping seat 231 and the motor rotor, thereby improving the clamping stability of the motor rotor.

The fixed section and the movable section of the first telescopic rod 31 are slidably connected at one end close to each other, so that the lifting seat 22 is driven to slide along the first direction by the sliding of the first telescopic rod 31 along the first direction, so that the lifting seat 22 drives the motor to rotate and drive it into the magnetization area 232 for magnetization.

[0036] Reference Figure 5 , when magnetization is completed, the motor rotor needs to be located outside the magnetization cavity 211 to facilitate material removal or subsequent magnetic flux detection. To this end, the sliding assembly 3 also includes a second elastic member 32, which is sleeved on the first telescopic rod 31. The telescopic direction of the second elastic member 32 is parallel to the first direction. The second elastic member 32 is fixedly connected between the base 1 and the lifting seat 22. In this embodiment, the second elastic member 32 is a compression spring.

In order to drive the mounting seat 42 to slide, the base 1 is also provided with a third cylinder 5, and the piston rod of the third cylinder 5 is parallel to the side wall of the slide groove 11. The piston rod of the third cylinder 5 is fixedly connected to the second slider 421, and the cylinder shell of the third cylinder 5 is fixedly connected to the base 1, so that the mounting seat 42 is driven by the third cylinder 5 to slide, and the motor rotor is driven to move through the first connecting seat 233.

[0041] The implementation principle of a fully automatic and efficient motor magnetizing device in the embodiment of the present application is as follows: before magnetization, the motor rotor is first placed in the magnetizing area 232 of the lifting seat 22, and the two clamping seats 231 clamp the rotor to stabilize it, the first cylinder 41 drives the pressing block 43 to slide along the first direction, thereby contacting the top wall of the motor rotor, and driving the motor rotor together with the lifting seat 22 into the magnetizing cavity 211, and the motor rotor is magnetized by the magnetizing seat 21, after the magnetization is completed, the first cylinder 41 drives the pressing block 43 to slide toward the side away from the lifting seat 22, and under the action of the second elastic member 32, the lifting seat 22 slides along the first direction toward the side away from the base 1, so that the motor rotor is located outside the magnetizing cavity 211, the second cylinder 235 drives the clamping seat 231 to clamp and fix the rotor, and the third cylinder 5 drives the mounting seat 42 to slide, so as to drive the motor rotor to move to the unloading area through the second telescopic rod 44 and the first connecting seat 233.
