Permanent magnet motor rotor permanent magnet assembling device and assembling method thereof

Abstract

Provided is a permanent magnet motor rotor permanent magnet assembling device. The device comprises a positioning seat, a material box and a feeding guide die, and the feeding guide die is provided with an assembling groove, a pushing groove and a slitting discharging port. The assembling groove is aligned with a permanent magnet groove in a rotor core. The slitting discharging port and the assembling groove are formed in the two ends of the pushing groove; the discharge port of the material box communicates with the pushing groove and the communication part is positioned between the assembling groove and the slitting discharging port; the material box is provided with a feeding part; the width of the pushing groove is larger than or equal to the width of the product permanent magnet and smaller than the sum of the widths of the product permanent magnet and a spacer. A pushing assembly moving in a reciprocating mode is arranged in the pushing groove, a slitting part used for pushing the spacer to the slitting discharging port is arranged on the pushing assembly, and a slitting discharging groove used for communicating with the material box discharging port and the slitting discharging port is formed in the side edge of the pushing groove. The assembling method comprises the following steps: positioning and feeding; assembling of a product permanent magnet;; and repeating of thesteps until all product permanent magnets in the material box are assembled. The device is simple in structure, low in cost and high in 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...

Problems solved by technology

But existing guide mold does not solve permanent magnet material 30 (permanent magnet material 30 comprises many pieces of product permanent magnets 32 and is located at the spacer 31 between adjacent two pieces of product permanent magnets 32) cutting and prevents permanent magnets from being installed incorrectly The problem is that the assembly efficiency is not high
