[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0022] In the description of this invention, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0024] The terms used in this invention, such as “above,” “over,” “below,” and “under,” indicating spatial relative position, are for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms of spatial relative position may be intended to include different orientations of the device in use or operation other than those shown in the figures. For example, if the device in the figures is flipped, a unit described as being “below” or “under” other units or features would be located “above” other units or features. Therefore, the exemplary term “under” can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or otherwise), and the spatially related descriptive terms used herein will be interpreted accordingly.

[0025] In this invention, unless otherwise explicitly specified and limited, the terms "set," "socket," "connect," "through," and "plug-in" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0026] like Figure 1 - Figure 4 As shown, a motor rotor shaft stabilizing clamping and rotating device of the present invention includes a side plate 1 and a front panel 2. A bracket 3 is mounted on the front panel 2. A guide shaft 4 is movably disposed on the bracket 3. A rotating assembly is mounted on the guide shaft 4. A clamping shaft 5 is disposed on the rotating assembly.

[0027] The bracket 3 is provided with a top plate 14; the lower surface of the top plate 14 is provided with a chuck 8 for clamping the rotor 7 and which is vertically opposite to the clamping shaft 5; the chuck 8 is fixed inside the clamping shaft 5; the outer wall of the chuck 8 presses against the inner wall of the clamping shaft 5.

[0028] A first axial movement assembly is installed between the side plate 1 and the panel 2; a second axial movement assembly is installed between the bracket 3 and the guide shaft 4.

[0029] In this embodiment, the second axial movement component includes a short-stroke cylinder 9, on which a first linkage bracket 10 is provided, and the first linkage bracket 10 is connected to the guide shaft 4.

[0030] The first axial movement assembly includes an axial movement screw mechanism 6, on which a second linkage bracket 11 is mounted to connect the side plate 1.

[0031] In this embodiment, the side plate 1 has one or more guide rails 12 on its surface; the panel 2 has a sliding groove on its surface; and the guide rails 12 are installed in the sliding groove.

[0032] In this embodiment, a fixed seat is provided on the panel (2), and one or more slide rods 15 are installed between the top plate 14 and the fixed seat; a servo motor 17 is installed on the panel 2.

[0037] 1. When the short-stroke cylinder is not working, the chuck clamping shaft is in the upper position, and the chuck is clamped by the chuck clamping shaft. If the motor rotor shaft is installed on the chuck, the motor shaft is clamped by the chuck and the chuck clamping shaft.
