Batch nut taking device

The utility model discloses a batch nut taking device which comprises a rotating disc seat and a rotating machine head used for driving the rotating disc seat to rotate, a plurality of nut taking mechanisms are fixed on the rotating disc seat and evenly distributed along the edge of the rotating disc seat, and each nut taking mechanism comprises a lifting air cylinder, a clamping block air cylinder and two clamping heads. The lifting air cylinder is fixedly connected with the rotating disc base, the clamping block air cylinder is fixedly connected to a telescopic rod of the lifting air cylinder, the two chucks are symmetrically arranged at the moving end of the clamping block air cylinder, semicircular end columns are formed at the lower ends of the chucks, and the semicircular end columns at the lower ends of the two chucks are symmetrically arranged. The two semicircular end columns are oppositely spliced to form a cylindrical structure capable of being inserted into the nut. Compared with a mechanism for s
