The centering support frame 1 includes a reference plate 11 and a horizontal support plate 12 fixed to each other. The reference plate 11 is provided with a first reference hole 1121.

The rotating shaft 201 of the motor 200 can be inserted into the positioning hole 21, and the diameter of the positioning hole 21 is equal to the diameter of the rotating shaft 201 of the motor 200. The horizontal support plate 12 can be fixed to the mounting base 202 of the motor 200 along the vertical direction Z. Since the horizontal motor 200 is not provided with a mounting stop, it cannot be quickly installed on the reference frame 100 in a centered manner. Therefore, the reference plate 11 is inserted into the second reference hole 1021 provided along the first horizontal direction X of the reference frame 100, so that the first reference hole 1121 on the reference plate 11 is coaxially arranged with the second reference hole 1021. Subsequently, the centering sleeve 2 is inserted into the first reference hole 1121 so that the axis of the positioning hole 21 coincides with the axis of the first reference hole 1121, thereby aligning the axis of the positioning hole 21 with the axis of the second reference hole 1021. Overlap. Since the diameter of the positioning hole 21 is the same as the diameter of the rotating shaft 201 of the motor 200, after the rotating shaft 201 of the motor 200 is inserted into the positioning hole 21, the axis of the rotating shaft 201 of the motor 200 overlaps with the axis of the second reference hole 1021, thereby achieving rapid alignment of the rotating shaft 201 of the motor 200 and the rotating shaft 201 of the second reference hole 1021 of the reference frame 100. At the same time, the horizontal support plate 12 can be fixedly connected to the mounting base 202 of the motor 200 along the vertical direction Z to achieve fixation of the motor 200 and the reference frame 100.

In this embodiment, the reference frame 100 is usually designed to be a structure for installing a vertical motor through a stopper, so it cannot realize the rapid centering of a horizontal motor. In addition, the second reference hole 1021 of this type of reference frame 100 has a larger aperture, and the reference plate 11 of the centering support frame 1 is too small, so it cannot be directly fixed to the reference frame 100. For this reason, the existing transition flange 111 is used to realize the fixation of the centering support frame 1 and the reference frame 100. Specifically, the first stop 1111 is coaxially arranged with the flange hole 1112 of the transition flange 111, and the second stop is coaxially arranged with the second reference hole 1021. One of the first stop 1111 and the second stop is a male stop, and the other is a female stop.

Specifically, a plurality of first threaded holes 22 are provided and arranged around the circumference of the centering sleeve 2 , a plurality of top screw bolts are provided, and the plurality of top screw bolts are arranged in one-to-one correspondence with the plurality of first threaded holes 22 .

[0041] Optionally, the centering support frame 1 further includes a first height adjustment member 13, which is disposed on a side of the horizontal support plate 12 close to the motor 200, and is used to support the mounting base 202 of the motor 200.
