1. A multi-degree-of-freedom numerical control turntable, comprising:
a B-shaft rotating assembly that includes a rotating connection land and a B-shaft power control mechanism for driving the rotating connection land to rotate around a B-shaft line;
a C2-shaft workbench rotating assembly that includes a movement base, a workbench and a C2-shaft power control mechanism for driving the workbench to rotate around a C2-shaft line on the movement base;
an S-shaft workbench movement assembly that includes a swing base and an S-shaft power control mechanism; and
a C1-shaft workbench swing assembly that includes a swing arm and a C1-shaft power control mechanism for driving the swing base to swing around a C1-shaft line on the swing arm, with the swing arm fixed on the rotating connection land and the C1-shaft line intersecting the B-shaft line,
wherein 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;
wherein the B-shaft rotating assembly is mounted on an X-axis motion base of a machine tool; the B-shaft line is perpendicular to the X-axis and Z-axis of the machine tool; the swing arm includes a swing arm base and a sector swing arm; the sector swing arm and the swing arm base are connected to form an L-shaped structure; the swing arm base is fixed on the rotating connection land; a sector surface of the sector swing arm is provided with a C1-shaft arcuate rail for supporting the swing base in an auxiliary manner; the sector surface of the sector swing arm is parallel to the B-shaft line; and a table top of the workbench is parallel to the B-shaft line.
