Description

Assembly fixture Technical Field The invention relates to the technical field of motor machining, in particular to an assembly fixture. Background One of the permanent magnets of the motor is called a motor magnetic shoe, and the function of the motor magnetic shoe is to serve as a permanent magnet to generate a constant magnetic potential source in the motor so as to convert mechanical energy into electric energy by utilizing the electromagnetic induction principle. In the assembly process of the motor, the assembly of the magnetic shoe is generally realized by a special fixture. In the prior art, assembly jig includes restraint post, restraint body and spacing post. The restraint body is arranged in the restraint column, and a plurality of restraint spaces for inserting magnetic steel are formed in the inner side wall of the restraint column. The spacing post is inserted and is established in the restraint post in order to ensure that the roof of a plurality of magnet steel flushes. When the fixture is used for assembling the magnetic steel, the limiting column is required to be inserted into the constraint column, the plurality of magnetic steels are sequentially inserted into the constraint space, the limiting column is taken out from the constraint column to insert the rotor into the constraint column, the constraint column is pressed down and the rotor is driven to move relative to the magnetic steel, so that the magnetic steel is inserted into the corresponding groove of the rotor, and the installation of the magnetic steel is completed. However, in the above process, when the rotor is required to be inserted into the constraint column, the grooves on the rotor are ensured to correspond to the magnetic steels, and at this time, the magnetic steels and the rotor are spaced at certain intervals and are all positioned inside the constraint column, so that the determination of the relative position between the two is difficult, more time is required to be spent for positioning, and the assembly process is time-consuming and has lower efficiency. Disclosure of Invention The invention aims to provide an assembly fixture, which solves the problems of more assembly time consumption and lower efficiency caused by higher positioning difficulty of a magnetic shoe and a rotor in the assembly process of the magnetic shoe in the prior art.
