Multi-station automatic rotation positioning structure

The invention relates to the field of jigs, in particular to a multi-station automatic rotating and positioning structure which comprises a CNC base, a rotating pull-down air cylinder and a product positioning module, and the driving end of the rotating pull-down air cylinder penetrates through the CNC base and is sequentially connected with an air cylinder connecting rod and a floating pull head; a disc assembly is further arranged on the upper surface of the CNC base, clamping grooves for containing the two ends of the floating puller are formed in the upper surface of the disc, a limiting pin and a positioning buckle are further installed on the CNC base, arc-shaped limiting grooves are formed in the two sides of the lower surface of the disc, positioning grooves are formed in the periphery of the lower surface of the disc, and the two ends of the floating puller are clamped in the clamping grooves in the upper surface of the disc. According to the multi-station automatic rotary positioning structure, the
