A production process and production equipment of a motor rotor for unmanned aerial vehicles

Abstract

The technical scheme of the present invention is achieved in this way: a production process for a motor rotor for an unmanned aerial vehicle, comprising the steps of: turning a rotor shaft blank, and heat-treating it in an electric melting furnace; and painting the surface for standby; The sheet is punched into a rotor sheet set for standby; the rotor sheet set and the rotor shaft are stamped and formed by the cooperation of the punching machine and the stamping die; the straightness of the rotor shaft of the rotor is tested, and the test is correct before leaving the factory. Compared with the prior art, the method disclosed in the present invention has the following beneficial effects: the production process is simple to operate, has lower technical requirements for the staff, and is suitable for more working groups; The quality is good, and the rotor shaft is immersed in oil. After the rotor shaft used for stamping is lubricated with oil, the insulating paint layer on the surface is not easy to wear, so as to avoid the leakage of the finished motor shaft.

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to a production process and production equipment of a motor rotor for an unmanned aerial vehicle. Background technique [0002] Motor (English: Electric machinery, commonly known as "motor") refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. [0003] The motor is represented by the letter M (the old standard is D) in the circuit. Its main function is to generate driving torque as a power source for electrical appliances or various machines. The generator is represented by the letter G in the circuit. Its main function The function is to convert mechanical energy into electrical energy. [0004] Electromagnetic DC motors are widely used on drones; electromagnetic DC motors are composed of stator poles, rotors (armatures), commutators (commonly known as commutators), brushe...

Problems solved by technology

[0004] Electromagnetic DC motors are widely used on drones; electromagnetic DC motors are composed of stator poles, rotors (armatures), commutators (commonly known as commutators), brushes, casings, bearings, etc.; the rotor at this stage is for To avoid the axial current generated by electromagnetic induction, a layer or even multiple layers of insulating paint will be coated on the outer surface of the motor shaft to prevent the generation of axial current during use and cause the motor to burn out; and the rotor at this stage The conventional production process is to manually stamp the motor shaft and rotor shaft directly through the traditional concave die. This method has low production efficiency, low degree of automation, and is prone to tilting, which will cause the insulating paint on the outer wall of the motor shaft to wear and damage the motor. performance is adversely affected
