There is often an oxide layer on the surface of the electronic rotor commutator, which often affects the commutation conductivity of the motor. For this reason, it is necessary to polish the surface of the commutator. However, the polishing of the existing commutator finishing machine can easily cause the surface of the commutator Dirty and poor roundness of the commutator finishing machine will affect the electrical conductivity of the motor and may cause unstable operation of the motor. As a result, a new type of commutator precision turning machine was developed.
One of the main purposes of this new type of commutator finishing machine is to cleanly remove the oxide layer on the surface of the commutator and to control the roundness of the commutator finishing machine. So, how is it achieved? Let us continue to look down.
The equipment consists of a workbench, a V-shaped seat, a power transmission device and a controller. It is characterized in that there are two V-shaped seats spaced apart on the worktable, and the two ends of the rotor with a wire wound and a commutator are installed. Respectively placed on a V-shaped seat, a fine turning tool is provided on the worktable and opposite to the commutator surface, and a copper meson opposite to the commutator is provided on the rotor, and the V-shaped seat on the corresponding side is fixed There is a separation distance between the position and the copper meson. The power device includes a motor and a belt, and the motor drives the rotor to rotate through the belt.
The new commutator precision turning machine has the following 2 advantages:
1. Put the wound rotor on the two V-shaped seats of the finishing machine, use the high-speed operation of the finishing machine belt, and cut the surface of the commutator finishing machine through the finishing tool, so as to make The oxide layer on the surface of the commutator is completely turned clean to ensure the commutation conductivity of the motor.
2. The roundness of the commutator finishing machine can be well controlled to ensure stable operation of the motor and improve work efficiency.
