Problems solved by technology
[0002] The existing rotor deflection measuring instrument (device) can only measure the deflection data of the whole rotor, and cannot be used to measure the deflection data of the rotor single piece. It is also not conducive to timely adjustment of the deviation of the stamping die
For the stamping die mentioned above, friction between the punch of the upper die and the small unloading plate will cause the precision of the punch to wear out, and the deflection data of the punched rotor single-piece product is large, which cannot be accurately found by using the original rotor deflection measuring instrument. The worn position of the punch in the stamping die, let alone the measurement of the deflection data of the single piece of the rotor, makes it impossible to accurately position the punch in the die, causing hidden dangers to product quality and adverse effects on subsequent production

The invention discloses a method and a device for measuring rotor uniwafer deflection. The measuring device comprises an engine base, a dial indicator arranged on one side of the engine base and a vertical rotor center shaft arranged on the other side of the engine base. The dial indicator is transversely placed and is fixedly arranged on a base through a dial indicator fixing board; a probe of the dial indicator points to the rotor center shaft; the lower part of the rotor center shaft can drive a center shaft sleeve rotated by the rotor center shaft, and the top of the rotor center shaft can be provided with an annular pressing ring which can be taken off from the rotor center shaft; and when a rotor uniwafer to be detected is sleeved on the center shaft, the rotor uniwafer to be detected is pressed between the annular pressing ring and the center shaft sleeve through the annular pressing ring. The method and the device for measuring rotor uniwafer deflection, provided by the invention, are particularly applicable to measuring deflection data of the rotor uniwafer, so that the deviation condition occurred in a process of machining the rotor uniwafer by a punching die can be found out in time, and the deviation occurred to the punching die is corrected in time.
Description
technical field [0001] The invention is applied to the field of stator and rotor punching, and in particular relates to a rotor deflection measurement method and a rotor deflection measurement device. Background technique [0002] The existing rotor deflection measuring instrument (device) can only measure the deflection data of the whole rotor, and cannot be used to measure the deflection data of the rotor single piece. The deviation situation is also not conducive to making timely adjustments to the deviation of the stamping die. For the stamping die mentioned above, friction between the punch of the upper die and the small unloading plate will cause the precision of the punch to wear out, and the deflection data of the punched rotor single-piece product is large, which cannot be accurately found by using the original rotor deflection measuring instrument. The worn position of the punch in the stamping die, let alone the measurement of the single-piece deflection data of ...
