Problems solved by technology

In the prior art, the calibration of the axis of the stator is usually done by measuring the distance between the stator and the relative position of the working platform to judge whether the stator has been corrected. However, this method has a high degree of error and cannot guarantee the assembly quality. The bearing is damaged or the stator and rotor are assembled. The abnormal sound of the rear bearing happens from time to time, and it is extremely time-consuming

Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] The invention discloses a calibration tool, which is installed on the thimble of a motor stator press-fitting machine 1, so that the calibration tool can extend into the bearing hole on the end cover of the stator 2 under the drive of the thimble to realize calibration. function, please refer to Figure 4 shown. Such as Figure 1-Figure 3 As shown, the correction tooling includes a main body part 3 and a correction part, specifically:

[0022] The main body 3 is a round rod coaxially arranged with the thimble.

[0023] The correction part includes a plurality of correction plates 4 arranged on the outer peripheral surface of the main body part 3 (the number of the correction plates 4 is not unique, but in order to ensure that it can realize the correction function of the axis of the stator 2, it should be at least on the main body Three correction plates 4...

Abstract

The present invention provides a calibration tool for installation on a thimble of a motor stator press-fitting machine. The calibration tool includes a main body and a calibration part. The main body is a round rod and is arranged coaxially with the thimble; The correction part includes a plurality of correction plates arranged on the outer peripheral surface of the main body part, the plate surfaces of each correction plate are parallel to the axial direction of the main body part, and the circumscribed circles of the correction plates The center of the circle is located on the axis of the main body, and the circumscribed circle matches the shape of the bearing hole on the end cover of the stator so that a plurality of the correction plates can fit into the bearing hole driven by the thimble . The calibration tooling of the present invention can calibrate the stator conveniently, quickly and accurately.

Description

technical field [0001] The invention relates to a correction tool, in particular to a correction tool for correcting the axial center of a stator. Background technique [0002] Permanent magnet motor is a kind of high-efficiency and energy-saving motor. With the vigorous promotion of the country, more and more users begin to choose permanent magnet motor to replace asynchronous motor. However, due to the huge suction force of the rotor magnetic steel, the installation of the stator and rotor can no longer be assembled manually. Usually, the motor stator pressing machine is used for the assembly of the stator and rotor. When operating, first place the stator on the platform and adjust its center height, then use the thimbles of the motor stator press machine on the two opposite support seats to withstand the bearing holes on the end covers located at both ends of the stator, and then remove the stator after tightening. The end cover at one end of the rotor is used to complet...
