Support for shaft machining

The utility model provides a support for shaft machining. The support for shaft machining comprises a support base, wherein a guide sleeve which extends vertically is arranged on the support base. The support for shaft machining is characterized in that a supporting screw which extends vertically is assembled on the guide sleeve in a guiding and moving mode through a threaded adjustment mechanism, a supporting frame used for supporting a machined shaft is assembled at the upper end of the supporting screw in a rotary mode, and the supporting frame is in pressing fit with the supporting screw through a pressing structure. According to the support for shaft machining, the supporting screw can be adjusted to move up and down simply through the threaded mechanism, the supporting frame used for supporting the machined shaft is arranged at the upper end of the supporting screw in a pressing and rotating mode, when the shaft with both ends needing to be machined is machined and turned, the machined shaft can be turned simply by rotating the supporting frame, other lifting tools are not needed any more, operation is convenient, and machining efficiency is greatly improved.
