[0027] like Figure 3 and Figure 4 As shown, the internal support structure includes an electric push rod 23 fixedly connected to the bottom end of the internal support box 2, the telescopic end of the electric push rod 23 is fixedly connected to the rising frame 24, the interior of the internal support box 2 is provided with an inner groove 22, and the internal circular array of the inner groove 22 is slidably connected to a plurality of internal support splints 25, and the outer wall of the inner support splint 25 is provided with a pressure groove 251 that cooperates with the rising frame 24 to form a sliding groove. At this time, the telescopic end of the electric push rod 23 rises, which can make the rising frame 24 squeeze the inner support splint 25 so that it can expand outward, and the outer wall of the inner support splint 25 is fixedly connected to the limit spring 26, and the end of the limit spring 26 is fixedly connected to the inner wall of the inner groove 22. During the translation of the inner support splint 25, the limit spring 26 can be compressed. When the rising frame 24 is no longer squeezed, the inner support splint 25 will be reset.

[0028] like Figure 3 and Figure 4As shown, the auxiliary fixture includes a servo motor 4 fixedly connected to the top of the base plate 1, the output end of the servo motor 4 is fixedly connected to a threaded screw 41, the outer wall of the threaded screw 41 is threadedly sleeved with a movable sleeve 42, the inside of the movable sleeve 42 is slidably connected to a rising plate 43, the upper top of the rising plate 43 is fixedly connected to an edge clamping plate 46 that is clamped to the edge plate 33, so that the position of the rising frame 43 inside the movable sleeve 42 can be adjusted to achieve the purpose of adjusting the position of the edge plate 33 according to the workpiece body 3, the outer side wall of the rising frame 43 is symmetrically provided with extrusion grooves 44, the outer side wall of the movable sleeve 42 is symmetrically threadedly connected with extrusion bolts 45 that extrude the rising plate 43, the end of the threaded screw 41 is provided with a bearing 47, the upper top of the base plate 1 is symmetrically fixedly connected with an external support frame 48, the end of the external support frame 48 is fixedly connected to the lower bottom end of the bearing 47, so as to provide corresponding support for the threaded screw 41.
