摘要： The present invention discloses a multi-degree-of-freedom numerical control turntable including: a B-shaft rotating assembly; a C1-shaft workbench swing assembly; a C2-shaft workbench rotating assembly; and an S-shaft workbench movement assembly. The B-shaft rotating assembly includes a rotating connection land and a B-shaft power control mechanism; the C2-shaft workbench rotating assembly includes a movement base, a workbench and a C2-shaft power control mechanism; the S-shaft workbench movement assembly includes a swing base and an S-shaft power control mechanism; and the C1-shaft workbench swing assembly includes a swing arm and a C1-shaft power control mechanism, with the C1-shaft line intersecting the B-shaft line. The S-shaft power control mechanism can drive the movement base to move along an S-shaft line on the swing base to cause a region to be machined of a workpiece to approach the intersection point of the C1-shaft line and the B-shaft line. The present invention adds the C1-shaft and S-shaft, so that when the cutting edge point participates in the motion, the coordinate change of the linear shaft is smaller, the compensation range of the linear shaft is smaller, the machining efficiency is higher, and the surface quality and machining accuracy are less affected by the accuracy of the linear shaft.
