Summary: | The invention discloses a main shaft end clamping block used in process of external grinding of two-end clamping of a rotating shaft without a center hole. Four internal screw thread through holes are symmetrically arranged in the main shaft end clamping block, one end of the main shaft end clamping block is provided with a placement groove, the other end of the main shaft end clamping block is provided with a convex block, and the internal screw thread through holes are communicated with the placement groove. In the invention, the rotating shaft without the center hole is clamped and located by the main shaft end clamping shaft for carrying out the external grinding; and during the processing, the processed rotating shaft is in a stable clamped and located state, the rigidity of the entirety of the rotating shaft is good, thereby being beneficial to obtaining good processing requirements, a grinded and processed external circle meets the design requirements and has good surface appearance quality. |
