Description

Technical Field

[0001] This utility model relates to the technical field of rotor production equipment, and in particular to a rotor core fixing fixture. Background Technology

[0002] As a high-precision device, the quality characteristics of an electric motor are directly determined by the assembly process and precision requirements during production. Therefore, strong collisions and contact must be avoided during assembly, otherwise the safety and stability of the motor during high-speed operation will be affected. In actual motor assembly production, clamping and fixing fixtures are generally required to achieve high-precision assembly of the motor rotor and stator.

[0003] Existing rotor fixing fixtures, such as the one disclosed in patent number CN 220586134 U, include a base with supporting threaded columns fixedly connected to the four corners of the upper end of the base. Two supporting threaded columns are slidably connected to connecting plates on their outer sides. Nuts are spirally connected to the upper outer ends of the supporting threaded columns. A fixing plate is fixedly connected to the center of the two connecting plates. A sliding plate is slidably connected to the upper end of the fixing plate, and a first Velcro strap is fixedly connected to the inner rear end of the sliding plate. This rotor core fixing fixture, through the fixed plate, sliding plate, supporting threaded columns, and rotor core, fixes the rotor core to the inside of the housing when it is assembled. This ensures the rotor core is positioned at the center of the stator core in the housing upon insertion, effectively improving the positioning accuracy of the rotor core and the subsequent assembly accuracy of the rotor core.

[0004] The aforementioned patent uses Velcro to fix the rotor core. This fixing method cannot guarantee stability during subsequent assembly, affects assembly accuracy, and cannot meet actual needs. Summary of the Invention
