To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in conjunction with the accompanying drawings is not intended to limit the scope of the present invention for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

The clamping plate 20 is mainly used as a clamping space to clamp and accommodate the stator sheets, and the base plate 10, the top plate 30 and the cover plate 40 constitute the two outermost plates to close the clamping plate 20.

[0027] Among them, a plurality of first positioning holes 11 are arranged in the middle of the bottom plate 10, and a plurality of first connecting holes 12 are arranged around the bottom plate 10 near the edge. The number and position of the positioning holes 11 can be adjusted according to the shape of the stator sheet. Five first positioning holes 11 are selected here, one in the center and four evenly surrounded. Six first connecting holes 12 are arranged here, distributed in a circular array.

[0028] Among them, a clamping hole 21 is set in the middle of the clamping plate 20, and the clamping hole 21 is used to place the stator sheet. Six second connecting holes 22 are arranged around the outside of the clamping hole 21, and the six second connecting holes 22 are distributed in a circular array. In addition, the inner wall of the clamping hole 21 is recessed inwardly and has four first positioning grooves 211. The edge shape of the stator sheet of the first positioning groove 211 corresponds to that of the stator sheet. Four first positioning grooves 211 are arranged here and are evenly distributed around.

[0029] In addition, an opening 31 is provided in the middle of the top plate 30, and the position of the opening 31 corresponds to the position and shape of the clamping hole 21. Six third connecting holes 32 are arranged around the outside of the opening 31, and the inner wall of the opening 31 is recessed inwardly to provide a plurality of second positioning grooves 311, wherein the positions and numbers of the first positioning grooves 211 and the second positioning grooves 311 correspond to each other.
