Assembling method and assembly for rotor magnetic pole box of permanent magnet half direct-driven wind turbine generator

Abstract

The invention discloses an assembling method and an assembly for a rotor magnetic pole box of a permanent magnet half direct-driven wind turbine generator. According to the method, an upright mounting technique is used and the method comprises the following steps: uprightly placing a rotor on a shaft pit; mounting the base of the assembly for the rotor magnetic pole box of the permanent magnet half direct-driven wind turbine generator on a screw rod on the upper end of a rotor pole base iron core; assembling the magnetic pole box by assembling one slot at one time, disassembling the assembledslot and exchanging and fixing the next slot in order to assemble the next slot; guiding the magnetic pole box into a guiding slot opening through a magnetic pole box guiding slot; driving the screw rod by using a servo motor; converting the rotary motion of the servo motor into the linear motion of a sliding base mechanism by the screw rod; pushing the magnetic pole box to a proper position, wherein the pushing force is adjusted by the servo motor; under the state of tightly pressing the magnetic pole box, driving a slot wedge pressing rod to lift upwards by a cylinder; manually putting intoa wedge; pushing a slot wedge pressing block by the cylinder through the slot wedge pressing rod; rushing the wedge tightly; lifting back by the cylinder; and welding the wedge in spot welding mannerby using argon arc welding, thereby finishing assembling one magnetic pole box.

Description

technical field [0001] The invention relates to a tooling method and device, in particular to a method for assembling a rotor pole box of a permanent magnet semi-direct drive wind power generator and a tooling device. Background technique [0002] The pole box of the motor is one of the important parts of the wind power generator. The pole box is mainly used for wiring the electromagnetic wire end and fixing the permanent magnet in the permanent magnet motor. Therefore, the quality of the pole box of the motor greatly affects the running quality of the motor. ; As for the pole box formed by stacking punched sheets, because the previous pole box assembly process was assembled by hand, only some simple auxiliary work tools were used, the operation method was relatively backward, and the pole box assembly It is too simple, so that the magnetic pole box is prone to misalignment and damage to the magnetic steel during the lamination process, so it needs to be further improved.
