Description

Technical Field

[0001] The utility model belongs to the technical field of motor production, and particularly relates to a clamping device for machining a motor rotor. Background Art

[0002] The motor rotor is a key rotating component inside the motor, working with the stator to realize the conversion between electrical energy and mechanical energy. The specific structure and working principle of the rotor vary according to the type of motor. The existing clamping device for motor rotor processing places the motor rotor to be clamped between the clamping tables on both sides, and drives the clamping plate close to the motor rotor through the drive module to achieve rapid clamping of the motor rotor. However, during the processing, the operation of the processing equipment may cause the motor rotor to vibrate, causing the motor rotor to shift to a certain degree, affecting the processing accuracy.

[0003] For example, the utility model with announcement number CN213054455U discloses a clamping device for rotor shaft production, including a horizontal plate, the top of the horizontal plate is fixedly connected to an electric telescopic rod, the output end of the electric telescopic rod is fixedly connected to a first connecting block, the side of the first connecting block away from the output end of the electric telescopic rod is movably connected to a connecting rod through a rotating rod, the end of the connecting rod away from the first connecting block is movably connected to a second connecting block through a rotating rod, the top of the second connecting block is fixedly connected to a first clamping plate, both sides of the top of the horizontal plate are fixedly connected to support plates, the top of the front of the support plate is fixedly connected to the second clamping plate, and the first clamping plate The surface of the limit sleeve is fixedly connected, the inner cavity of the limit sleeve is provided with a limit rod, and the bottom of the limit rod is fixedly connected to the top of the cross plate. In the technical solution of this patent, the operation of the electric telescopic rod makes the connecting rod drive the first clamping plate and the second clamping plate to approach to quickly and stably clamp the motor rotor placed between the first clamping plate and the second clamping plate. However, in the actual processing process, due to the single clamping direction, the processing equipment vibrates during the processing of the motor rotor, which will drive the motor rotor to vibrate, so that the motor rotor may move to a certain degree of position deviation, affecting the processing accuracy.
