Abstract

The invention discloses a bonding protection tool and a bonding protection method for rotor magnetic steel of a permanent magnet motor, solving the problem that in the prior art, when rotor magnetic steel is assembled, bonded magnetic steel easily repels the magnetic steel which is being assembled to fly out. A sleeve (5) movably sleeves a rotating shaft (1); the sleeve (5) rotates around the rotating shaft (1) by taking the rotating shaft (1) as a central axis; a rotor core (2) is arranged in the sleeve (5); a magnetic steel assembling window (6) is arranged on the cylindrical side surface ofthe sleeve (5); bonded magnetic steel (3) is arranged on the outer surface of the right end of the rotor core (2) in the magnetic steel assembly window (6); magnetic steel (4) being assembled is arranged on the left side of the bonded magnetic steel (3) in the magnetic steel assembly window (6); and a magnetic steel assembly push rod (9) is movably inserted into a magnetic steel assembly push rodinsertion through hole (8). The personal safety of assembly personnel is ensured, and the working intensity of magnetic steel attachment is also reduced.

Description

Technical field [0001] The invention relates to a sticking protection tool for permanent magnet motor rotor magnets, in particular to a sticking protection tool for permanent magnet motor rotor magnets and a protective sticking method. Background technique [0002] Some permanent magnet motor rotors are composed of a rotating shaft, magnets, punching sheets, left and right pressure plates, and screws. After the punching sheet is tightened by four screws in the axial direction, there are eight welds on the outer circle to realize the core overlap between the magnets. The front and rear ends of the aluminum magnetic strip are connected with screws and front and rear pressure plates. The magnetic steel is bonded in the groove of the iron core with 366 anaerobic glue. The magnetic steel is axially fixed by groove-shaped block and magnetic steel pressure plate. Connect with the rear pressure plate with screws, and finally the outer surface of the rotor is fastened with carbon fiber ho...
