Assembling and disassembling tool for disk type permanent magnet motors and method for installing motor end covers

Abstract

The invention discloses an assembling and disassembling tool for disk type permanent magnet motors. The assembling and disassembling tool is used in the field of disk type permanent magnet motors and comprises guide rails, two seat frames, two fixing plates and fixing devices, wherein the seat frames perpendicular to the guide rails are respectively positioned at two ends of the guide rails, the two fixing plates are positioned between the two seat frames, and motor end covers can be fixed onto the fixing plates by the fixing devices; and the fixing plates at the two ends of the guide rails are connected with the seat frames by two pair of scissor jacks, apexes perpendicular to the seat frames are arranged in centers of the seat frames, through holes which are concentric with the apexes are arranged in centers of the fixing plates, and the apexes penetrate through the through holes of the centers of the fixing plates when the scissor jacks contract. The assembling and disassembling tool has the technical advantages that a rotor can be effectively prevented from being sucked onto the motor end cover on an optional side of the rotor under the action of magnetic force, and a step for adjusting a gap between each motor end cover and the rotor is omitted; the motor end covers of a disk type permanent magnet motor can be accurately and quickly installed; and collision of coils due to single-side absorption is prevented, fingers of operators cannot be pinched due to high attractive force of magnetic steel, and the safety is greatly improved during motor assembly.

Description

technical field [0001] The invention relates to a disc permanent magnet motor dismounting tool used in the field of disc permanent magnet motors and a method for installing an end cover of the motor. Background technique [0002] Due to the magnetic force during the assembly process of the disc permanent magnet motor, the cooperation between the end cover with the stator and the rotor is not easy to control during assembly, and it is easy to be unilaterally adsorbed and collide with the coil, so the motor assembly cannot be completed accurately, quickly and safely. At present, the assembly of the disc permanent magnet motor is to use a fixing device to fix the two end covers of the disc motor on the flat plate respectively, hoist the rotor between the two in turn, and then continuously adjust the gap between the end cover and the rotor. until installed in place. [0003] In the current installation process, since the rotor is attracted to the end cover under the action of m...

Problems solved by technology

Due to the unilateral adsorption, it is easy to bump the coil, and because of the strong suction of the magnetic steel, it is easy to pinch your fingers, which adds unsafe factors
