The utility model discloses a main shaft end clamp splice used in a two end clamping process for excircle grinding of a rotating shaft without a center hole. The main shaft end clamp splice is characterized in that four internal threaded through holes are symmetrically arranged on the main shaft end clamp splice; a placement groove is arranged at one end of the main shaft end clamp splice and a lug is arranged at the other end of the main shaft end clamp splice; and the internal threaded through holes are communicated with the placement groove. The main shaft end clamp splice has the following beneficial effects that: the rotating shaft without the center hole is clamped and positioned by the main shaft end clamp splice to undergo excircle grinding machining; in the machining process, the machined rotating shaft is always in the stable clamping and positioning state, has good integral stiffness and is beneficial to gaining good machining requirements; and the excircle machined by grinding conforms to the desi
