Embodiment Construction
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0020] see figure 1 , in an embodiment of the present invention, a method for manufacturing a rotor, comprising the following steps:
[0021] S1. Laminate the rotor punching sheets to form the rotor iron core 2, which is processed and formed at one time. The rotor iron core 2 is welded to the rotating shaft 1 through steel materials;
[0022] S2. Insert the permanent magnet 3 into the arc-shaped groove provided on the tooling 4, and position it through the ax...

The invention discloses a rotor production method and a corresponding tooling thereof. The rotor production method comprises the following steps: step S1, welding a rotor core to a rotating shaft through a steel material; step S2, inserting a permanent magnet into an arc groove provided on the tooling and positioning the permanent magnet by an axial positioning device; step S3, applying glue to abonding surface of the permanent magnet and the rotor core; step S4, inserting the rotor core into the inner side of the permanent magnet, and enabling the rotor core and the permanent magnet to be bonded; and step S5, taking down the tooling and completing the rotor production. According to the rotor production method provided by the invention, the design is novel; the rotor core and the rotatingshaft are welded into a whole, and are formed in a one-time machine-shaping mode, so that the production time and the production cost are saved; and due to the arrangement of the tooling, the limiting of the permanent magnet is not required to be independently added on the rotor core, so that the production efficiency is improved and the installation is convenient.
Description
technical field [0001] The invention relates to the field of rotor processing, in particular to a rotor manufacturing method and corresponding tooling. Background technique [0002] The rotor refers to a rotating body supported by bearings. An object without its own axis of rotation, such as a disc, can be considered a rotor when it is rigidly connected or has an additional axis. [0003] In the surface-mounted rotor of a permanent magnet motor, the permanent magnets are usually arranged with a gap between them, which not only saves materials, but also optimizes electromagnetic performance. In this type of rotor, the axial positioning of the magnetic steel is usually accomplished by setting protrusions on the rotor core. One way is to directly process the rotor core when punching the rotor core; the other is to mill the rotor core, but either way will increase the manufacturing cost of the rotor core .
