The utility model discloses a rotating disk positioning mechanism for a drill, which relates to a rotating disk positioning mechanism for a drill. V-shaped positioning blocks are arranged on four sides of a rotating disk; two groups of V-shaped positioning blocks are arranged on each side and distributed crosswise; each group of V-shaped positioning blocks comprise a lower positioning block arranged on a rotating beam disk and an upper positioning block arranged on a rotating disk box; the upper positioning block is adapted to the lower positioning block; the upper positioning block contacts with the rotating disk; and threaded holes are arranged in the longitudinally corresponding positions on the upper positioning block and the lower positioning block. The rotating disk positioning mechanism positions the rotating disk by adopting the characteristic of self-centering of the V-shaped blocks, and limits two freedom degrees of the rotating disk by adopting fastening pieces, such as bolts, and has the following
