Description

Technical Field

[0001] The utility model relates to the technical field of motor rotor installation, and particularly relates to a high-precision rotor core magnetic steel inserting device. Background Technique

[0002] A permanent magnet motor usually consists of a rotor and a stator. The common rotor core adopts a structure form with internally inserted magnetic steel. A magnetic steel made of a permanent magnet material is inserted into the rotor core. As the rotating mechanism of the motor, it interacts with the rotating magnetic field generated by the stator, causing the rotor to rotate and generating the output of the motor. During the production and manufacturing process of the rotor core, the magnetic steel needs to be inserted into the corresponding position of the core.

[0003] For example, the utility model with the application number CN202221385425.5 relates to the technical field of motor rotor assembly. This device can automatically complete the operation of inserting magnetic steel into the rotor core, and can insert two magnetic steels at a time, saving manpower, effectively improving the assembly efficiency and product quality, and reducing the production cost; however, when the existing rotor core magnetic steel inserting device manually places the rotor on the insertion table, it is prone to deviation from the installation hole of the magnetic steel, affecting the disassembly and assembly accuracy and easily leading to disassembly and assembly failure, thus causing damage to the magnetic steel or the rotor.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a high-precision rotor core magnetic steel inserting device is provided. Content of the Utility Model

[0009] Furthermore, the limiting component further includes an adjusting block and a limiting rod. The adjusting block is arranged outside the lead screw, and the limiting rod is mounted on the surface of the adjusting block.

[0010] Furthermore, a feeding component for feeding the magnetic steel is arranged inside the processing table. The feeding component includes a feeding groove and a pushing plate. The pushing plate is installed in the feeding groove through an electric push rod.

[0011] Furthermore, the feeding component further includes a moving hole and a cover plate. A moving hole is opened at the lower end of the end of the feeding groove, and a cover plate is arranged at the upper end of the feeding groove.

[0012] Furthermore, an inserting component for providing the power for inserting the magnetic steel is arranged at the lower end of the processing table.

The positioning rod is inserted into the magnetic steel hole before the magnetic steel is pre-installed inside the rotor, so that the magnetic steel hole and the auxiliary hole of the rotor are aligned, ensuring high precision when the magnetic steel is inserted into the rotor and avoiding damage to the rotor and the magnetic steel caused by deviation.

[0016] 2. The utility model controls the movement of the mounting frame, etc. through the expansion and contraction of the third hydraulic rod. The lead screw is driven by a motor to adjust the height position of the adjusting block. The limiting rod moves along with the movement of the adjusting block. At this time, the adjusting block and the limiting rod respectively play a limiting role by aligning from the outside and the upper end of the rotor.

[0023] As Figure 2As shown in the figure, the positioning component 3 for increasing the precision of magnet insertion is arranged at the output end of the first hydraulic rod 2. The positioning component 3 includes a mounting frame 301, a mounting table 302, a second hydraulic rod 303, a fixing plate 304, a limiting hoop 305 and a positioning rod 306. The mounting table 302 is installed in the middle of the mounting frame 301, and the second hydraulic rod 303 is installed on the outside of the mounting table 302. The telescopic movement of the second hydraulic rod 303 controls the position movement of the fixing plate 304 and the limiting hoop 305. The output end of the second hydraulic rod 303 is installed with the fixing plate 304, and the limiting hoop 305 is installed on the surface of the fixing plate 304. The limiting hoop 305 and the inner wall of the mounting frame 301 play a role in clamping and limiting the positioning rod 306. The positioning rod 306 is arranged inside the limiting hoop 305. Before the internal magnet of the rotor is pre-installed, the positioning rod 306 is inserted into the magnet hole, so that the magnet hole of the rotor is aligned with the auxiliary hole 6, ensuring high precision when inserting the internal magnet of the rotor and avoiding damage to the rotor and the magnet caused by deviation.

[0024] As Figure 3 shown in the figure, a feeding component 8 for magnet feeding is arranged inside the processing table 4. The feeding component 8 includes a feeding groove 801 and a pushing plate 802. The pushing plate 802 is installed inside the feeding groove 801 through an electric push rod. The feeding groove 801 is used for placing the magnet.

[0025] In summary, for this high-precision rotor core magnet inserting device, first according to Figures 1-3In the structure shown in the figure, the rotor is placed on the auxiliary disk 5 so that the magnet holes and the auxiliary holes 6 are initially aligned. Then, the elongation of the first hydraulic rod 2 is controlled so that the positioning rod 306 is inserted into the magnet holes before installation, aligning the magnet holes of the rotor with the auxiliary holes 6, ensuring high precision during the insertion of the magnets in the rotor and avoiding damage to the rotor and magnets caused by deviation. After alignment, the elongation of the third hydraulic rod 701 is controlled to push the installation frame 702 to move closer to the outer side of the rotor. At the same time, the screw rod 703 is driven by the motor to adjust the height position of the adjustment block 704, causing the limiting rod 705 to press down on the upper end of the rotor. At this time, the adjustment block 704 and the limiting rod 705 respectively play a limiting role by aligning from the outer side and the upper end of the rotor. After the rotor is positioned, the first hydraulic rod 2 is controlled to contract so that the positioning rod 306 is withdrawn from the magnet holes. The magnet pre-stored in the feeding trough 801 is pushed to one side of the movable hole 803 by the pushing plate 802 controlled by the electric push rod. During the pushing process, the cover plate 804 prevents the magnet from protruding from the feeding trough 801 when moving. When the magnet moves to the position of the movable hole 803, the elongation of the fourth hydraulic rod 902 is controlled to push the control plate 903 upward, so that the ejector plate 904 pushes a single magnet upward through the movable hole 803 to install it in the magnet hole.
