Description

Technical Field

[0001] The utility model relates to the technical field of burr cleaning of motor casings, and specifically relates to a burr cleaning device for the production of casings of high-power propeller motors of unmanned aerial vehicles. Background Technique

[0002] The high-power propeller motor of an unmanned aerial vehicle is the main power source of the unmanned aerial vehicle. As one of the most common power components, the motor mainly consists of a casing, a stator, a rotor, and an output shaft. The casing, as the protective cover and support of the entire motor, is mainly manufactured by casting. After casting and forming, there will be certain burrs on the surface. Before assembly, a cleaning device is required to clean the burrs.

[0003] The utility model disclosed in the utility model patent with the authorization announcement number CN219617343U discloses a burr cleaning device for motor casings in motor production, including a base. An installation frame is installed on the top of the base. An installation plate is slidably installed on the inner wall of the installation frame. A rotating disk is rotatably installed at the bottom of the installation plate. A plurality of fixing rings are installed at the bottom of the rotating disk. A casing is placed on the top of the base. Both sides of the top of the base are provided with sliding grooves in the length direction. A sliding block is slidably installed in the sliding groove. A clamping rod is installed on the top of the sliding block. The outer wall of the clamping rod abuts against the casing. A communication hole is provided in the outer wall of the sliding groove away from the side of the base in the length direction. The two sliding grooves are communicated with each other through the communication hole. A bidirectional threaded rod is rotatably installed on the inner wall of one end of the communication hole. The other end of the bidirectional threaded rod penetrates through the base and is installed with an adjusting block. Although this device drives four clamping rods through the bidirectional threaded rod to push the casing to move to the exact center of the inner top of the installation frame, so that the top of the casing can accurately enter between two adjacent fixing rings at the bottom of the rotating disk, which is convenient for the rotating disk and the fixing rings to clean the burrs at the corner positions of the top of the casing. However, when removing burrs from the motor casing, this device cannot automatically convey and position the motor casing, thus reducing the efficiency of burr removal from the motor casing. And it is not convenient to centrally collect the burr fragments generated by burr removal and the dust generated by grinding, making the fragments and dust easy to fly around, resulting in low practicability. Therefore, we provide a burr cleaning device for the production of casings of high-power propeller motors of unmanned aerial vehicles to solve the above problems. Content of the Utility Model
