The following detailed description is made with reference to the accompanying drawings and examples:

referring to fig. 1, a winding jig according to an embodiment of the present invention includes a first jig 10 and a second jig 20.

The first clamp 10 and the second clamp 20 can clamp the stator m together along the first direction x, so that the wire n is wound around the outer circumference of the stator m. Here, the first fixture 10 and the second fixture 20 are respectively disposed at two ends of the stator m along the first direction x, and the first fixture 10 and the second fixture 20 abut against the stator m in the first direction x in an opposite manner to clamp the stator m together; when the wire body n is wound on the periphery of the stator m, the free end of the wire body n is located beside the stator m, and the first clamp 10 and the second clamp 20 rotate around the axis of the first direction x, so that the wire body n is pulled and surrounds the periphery of the stator m around the first direction x. The first clamp 10 and the second clamp 20 are respectively arranged at two ends of the stator m in the first direction x, so that the first clamp 10 and the second clamp 20 can sufficiently avoid the stator m, the stator m is exposed, and a wire body n is convenient to wind around the periphery of the stator m.

One end of the first fixture 10 in the second direction y is formed with a avoiding inclined plane 101, and the avoiding inclined plane 101 is used for avoiding the wire n when the wire n is obliquely wound towards the first fixture 10 on one side of the stator m in the second direction y. It should be noted that, during winding, the wire n generally surrounds the periphery of the stator m in the first direction x, but according to actual winding requirements, the wire n sometimes needs to be wound toward the first fixture 10 along the first direction x, and at this time, the wire n is easy to touch and scratch the first fixture 10; when the wire n is wound to one side of the stator m in the second direction y and is ready to be wound in an inclined manner towards the first fixture 10 along the first direction x, the position-avoiding inclined plane 101 can avoid the wire n in the inclined manner, i.e., the position-avoiding inclined plane 101 is arranged, so that the wire n can avoid the first fixture 10 in the inclined manner, and thus, the wire n cannot scratch the first fixture 10 to cause damage to the wire n during winding. The first direction x is perpendicular to the second direction y, where perpendicular means substantially perpendicular, that is, a certain deviation between the first direction x and the second direction y is allowed. It should be added that, since the clearance inclined plane 101 is for avoiding the wire n when the wire n is wound on one side of the stator m in the second direction y and is inclined towards the first fixture 10 along the first direction x, the second direction y here needs to be set according to a situation that the wire n is wound on one side of the stator m in which direction, that is, after it is determined that the wire n is wound on one side of the stator m in which direction, one end of the first fixture 10 in the corresponding direction is cut, so as to form the clearance inclined plane 101; alternatively, in this embodiment, as shown in fig. 1 and fig. 2, the second direction y is the height direction of the stator m, the avoiding inclined plane 101 is located at one side of the first fixture 10 in the height direction, and correspondingly, the wire n is wound to the one side of the stator m in the height direction and is inclined toward the first fixture 10 along the first direction x.

The vertical axis of the avoiding inclined plane 101 forms an included angle larger than 0 ° with the first direction x and is not perpendicular. It should be noted here that the vertical axis of the avoiding inclined plane 101 and the first direction x form an included angle greater than 0 ° and are not perpendicular, then the first direction x is not perpendicular to the avoiding inclined plane 101, nor is parallel to the avoiding inclined plane 101, and a side surface of the first fixture 10 on the first direction x is used for abutting against the stator m, so as to help ensure an area of the first fixture 10 used for abutting against the side surface of the stator m along the first direction x, help ensure a clamping force of the first fixture 10 on the stator m, and thus ensure smooth winding operation of the stator m.

In this embodiment, the wire body n is a copper wire; of course, in some alternative embodiments, the wire body n may also be configured as an aluminum wire or other metal wire according to actual use requirements.

In the embodiment of the application, the first clamp 10 and the second clamp 20 can clamp the stator m together along the first direction x so that the wire n is wound on the periphery of the stator m, and thus, when the stator m is wound, the first clamp 10 and the second clamp 20 are respectively arranged at two ends of the stator m along the first direction x so as to avoid the stator m, reduce interference between the stator m and the winding clamp, and facilitate the winding operation of the stator m; and, keep away position inclined plane 101's vertical axis and first direction x and form the contained angle that is greater than 0 and out of plumb, keep away position inclined plane 101 and be used for keeping away the line body n when the first anchor clamps 10 slope is around establishing at the stator m one side on second direction y when keeping away position inclined plane 101, like this, when the line body n is around establishing to the stator m along one side on the second direction y to when the first anchor clamps 10 slope is around establishing, keep away position inclined plane 101 makes first anchor clamps 10 avoid slope this moment around establishing line body n, so slowed down line body n and scraped the first anchor clamps 10 when slope is around establishing and led to the impaired problem, also further facilitated stator m's winding operation simultaneously.

Like this, stator m is spacing in first profile groove 102 and second profile groove 201 respectively along the relative both ends on first direction x, helps improving the location of stator m on first anchor clamps 10 and second anchor clamps 20 to help first anchor clamps 10 and second anchor clamps 20 to drive stator m steadily and rotate, so that the periphery of stator m is located around the line body n.
