Embodiment Construction
[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0031] Figure 1 to Figure 7 An embodiment of the permanent magnet assembling device and the assembling method of the permanent magnet motor rotor of the present invention is shown.
[0032] 1), mold assembly and feeding:
[0033] Such as figure 1 with figure 2 As shown, after the assembly of the permanent magnet assembly device of the permanent magnet motor rotor is completed, the positioning seat 24 is directly pressed on the upper end surface of the rotor core 11, and the positioning part 241 is positioned with the rotor 10 to ensure that the assembly groove 225 of the permanent magnet assembly device is aligned with the rotor core. 11. The permanent magnet slots inside are aligned up and down. The positioning component 241 can be a positioning key or a positioning pin according to the structural design of the rotor core 11, a...

The permanent magnet assembly device of the permanent magnet motor rotor includes a positioning seat, a material box and a feeding guide mold. The feeding guide mold is equipped with an assembly groove, a push groove, and a cutting outlet, and the assembly groove and the permanent magnet groove in the rotor core Alignment, the slitting outlet and the assembly groove are set at both ends of the push groove, the outlet of the material box is connected to the push groove and the connection is between the assembly groove and the slitting outlet, and the material box is equipped with a feeding Components, the width of the push groove is greater than or equal to the width of the permanent magnet of the product and less than the sum of the width of the permanent magnet of the product and the spacer. There is a reciprocating pushing component in the pushing groove. The slitting part of the slitting and discharging port is provided with a slitting and discharging chute for communicating with the discharging port of the material box and the slitting and discharging port on the side of the pushing groove. The assembly method includes the steps of: positioning and feeding; assembling the product permanent magnet; removing the spacer; repeating the above steps until the assembly of all the product permanent magnets in the material box is completed. The invention has simple structure, low cost and high assembly efficiency.
Description
technical field [0001] The invention relates to permanent magnet motor assembly equipment and methods, in particular to a permanent magnet motor rotor permanent magnet assembly device and an assembly method thereof. Background technique [0002] The permanent magnet is one of the key accessories of the permanent magnet motor rotor. Due to the strong magnetic force between the permanent magnets, the separation of the permanent magnets and the process of placing the permanent magnets into the permanent magnet slots of the rotor are difficult to operate during the manual embedding process. High, strong work intensity. For large-scale production, in order to improve assembly efficiency and assembly quality, most of them use special magnetic steel assembly machines or assembly manipulators for installation, but the cycle of manufacturing, installation and debugging of assembly equipment is long (usually 6 to 12 months), and the cost Very high, so not suitable for small batch pro...
