Description

Technical Field

[0001] The utility model relates to the technical field of motor manufacturing, in particular to a cast aluminum rotor press-fitting device. Background Art

[0002] The cast aluminum rotor is a high-efficiency and energy-saving motor rotor with light weight, high strength, excellent thermal conductivity and electrical conductivity. It is widely used in motors and compressors. The cast aluminum rotor is formed by extruding a plurality of rotors. Rotors of different specifications can be press-fitted by clamping, so that cast aluminum rotors of different sizes can be manufactured on one press-fitting device, reducing factory costs.

[0003] After searching, the announcement number CN218109303U discloses a motor iron core cast aluminum rotor die-casting device. The utility model stepper motor drives the transmission rod to rotate, and the rotation angle of the transmission rod is more precise. The transmission rod drives the two cams to rotate, and the cam is in close contact with the pressure wheel. When the cam rotates, the pressure wheel seat on the pressure wheel pushes the connecting rod to pass through the stepped cavity and move downward, and under the action of the pressure wheel seat and the bottom surface of the upper cavity, the spring is squeezed, so that the spring undergoes elastic deformation, and the connecting rod drives the connecting pressure block into the corresponding die-casting cavity, realizing the continuous die-casting process of the cast aluminum rotor and automatic operation; the push cylinder pushes the die-casting seat to be located at the end of the top surface of the substrate, which is convenient for injecting the cast aluminum die-casting liquid of the rotor into the die-casting cavity, and the push cylinder pushes the die-casting seat to slide on the substrate. Under the sliding cooperation of the guide block and the guide groove, the die-casting seat smoothly reaches the bottom of the mounting plate. In this application, it is impossible to press-fit rotors of different sizes and after the press-fitting is completed, the rotor needs to be removed manually, thereby reducing the work efficiency.
