Embodiment Construction
[0036] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and not to limit the present invention.
[0037] In the present invention, if there is no explanation to the contrary, the directional words used such as "up, down, left, right" generally refer to the up, down, left, and right shown in the drawings; "inside, outside" It refers to the inside and outside relative to the contour of each component itself.
[0038] One aspect of the present invention provides a rotor correction device that includes a correction rod 1 installed in an inner hole of a rotor 10 and a punching die for punching the outer peripheral surface of the rotor 10. The stamping die has a cavity adapted to the outer peripheral surface of the rotor 10 when the rotor 10 is stamped.

The invention relates to the field of rotor manufacturing, and discloses a rotor correction device and method. The rotor correction device comprises a correction bar and a stamping die, wherein the correction bar is installed in an inner hole of a rotor, and the stamping die is used for stamping the peripheral surface of the rotor. The stamping die is provided with a die cavity which is matched with the peripheral surface of the rotor when the rotor is stamped. Since the correction bar is installed in the inner hole of the rotor, the peripheral surface of the rotor is stamped through the stamping die, and the stamping die is provided with the die cavity which is matched with the peripheral surface of the rotor when the rotor is stamped, during stamping, the inner diameter and the outer diameter of the rotor can be squeezed at the same time for uniform stress, the problem that the correction bar is likely to be fractured when the correction bar is manually knocked is avoided, tool lossis reduced, the rotor straightness and compactness are improved, the problem that a riveting column is deformed due to the fact that the stamping die and the riveting column produce interference is avoided, the quality of the corrected robot is ensured, meanwhile, the correction efficiency is high, and automatic production can be achieved.
Description
Technical field [0001] The invention relates to the field of rotor manufacturing, in particular to a rotor correction device and a rotor correction method. Background technique [0002] Die-casting technology is often used when casting aluminum for fixed-speed compressor rotors. Due to the high pressure of the die-casting machine, the rotor core is prone to deformation, which makes the inner diameter surface of the rotor uneven, and the inner diameter is poor in straightness, which cannot meet the relevant process requirements. Therefore, before installing the balance weight on the rotor by riveting, it is usually necessary to perform a calibration process for the inner hole of the rotor. [0003] The existing correction method generally manually knocks the correction rod into the inner hole of the rotor, and knocks the handle of the correction rod on the side to force the inner hole of the rotor to expand, so that the inner diameter of the rotor is flat and the inspection gauge ca...
