Positioning and clamping tool for C-shaped symmetrical notch workpiece

A positioning and clamping tool for a C-shaped symmetrical notch workpiece comprises a base, a floating clamping mechanism, two bottom supporting mechanisms, two centering and clamping mechanisms, four side face clamping mechanisms, an electromagnetic chuck and a detection switch are arranged on the base, the two bottom supporting mechanisms are arranged on the right side of the floating clamping mechanism, and the two centering and clamping mechanisms are arranged on the right side of the floating clamping mechanism. The two centering clamping mechanisms are arranged between the two bottom supporting mechanisms. Clamping points are reasonably distributed, the bottom supporting mechanism is adopted for supporting, the electromagnetic chuck is adopted for adsorption, the centering clamping mechanism is adopted for positioning and centering, and the floating clamping mechanism is adopted for floating clamping, so that automatic positioning and clamping of a workpiece are achieved, the consistency of clamping an
