When the connection hole size of the headstock connection plate is consistent with the installation screw hole size of the rotor shaft end, it can be installed directly; otherwise, it is necessary to machine a matching connection screw hole at the rotor shaft end according to the connection hole size of the headstock connection plate of the machine tool, which is a cumbersome, time-consuming and labor-intensive process. In particular, the design of some workpieces does not allow the processing of connection holes, resulting in the inability to directly process the workpiece, requiring the replacement of the machine tool, and high production costs.

[0012] Furthermore, the waist-shaped holes on the shaft end flange are arranged radially and uniformly around the shaft end flange at the periphery of the connecting portion, with the connecting portion as the center.

[0013] The outer diameter of the flange at the machine end of the transfer tool corresponds to the outer diameter of the connecting portion, and the flange at the machine end and the connecting portion form a coaxial connection;

[0014] The screw holes on the machine end flange are evenly arranged around the machine end flange on the inner periphery of the connecting portion.

[0015] The connecting portion of the transfer tool is a hollow cylindrical structure.

[0016] The wall thickness of the connecting portion is 30-50 mm, and the axial length is 350-450 mm.
