Detailed Description

The present invention is described in detail with reference to the embodiments shown in the drawings, but it should be understood that these embodiments are not intended to limit the present invention, and those skilled in the art should understand that the functions, methods, or structural equivalents or substitutions made by these embodiments are within the scope of the present invention.

The stator core rounding mechanism shown in fig. 1-5 comprises a cam plate 5, a servo motor 13 for driving the cam plate 5, a clamping jaw base plate 12, a positioning sleeve 10 arranged on the clamping jaw base plate 12, a core rod 11 arranged on the positioning sleeve 10, twelve stators 111 attached to the outside of the core rod 11, clamping jaws 9 for extruding the outside of the stators 111, twelve clamping jaw fixing plates 7 in sliding fit with the clamping jaw base plate 12, and roller followers 6 connected with the clamping jaw fixing plates 7. The clamping jaw 9 is connected to the clamping jaw fixing plate 7.

The core rod 11 and the inner hole of the stator 111 are in small interference fit, and the roundness of the inner ring of the stator 111 is guaranteed. The positioning sleeve 10 is arranged at the center of the clamping jaw bottom plate 12, the core rod 11 is placed at the center of the positioning sleeve 10, and the lower end of the stator 111 abuts against the positioning sleeve 10, so that the lower ends of twelve stators 111 can be aligned, and the problem of misalignment of scattered sheets caused by manual hooping is solved.

Twelve sliding grooves 121 are formed in the clamping jaw bottom plate 12, sliding blocks 71 are arranged on the clamping jaw fixing plate 7, and the sliding blocks 71 slide in the sliding grooves 121, so that the linear motion of the clamping jaw fixing plate 7 is supported and guided.
