The utility model provides a novel floating chuck and belongs to the technical field of machinery. The novel floating chuck comprises a shell and a clamping mechanism used for clamping a workpiece. The clamping mechanism comprises a fixing base and a driving disk. The front portion of the fixing base is provided with a main clamping part and a plurality of auxiliary clamping parts. The auxiliary clamping parts are fixedly arranged on the fixing base. The head end of the main clamping part is connected to the fixing base in a hinged mode. The tail end of the main clamping part is connected with the driving disk. The fixing base is movably connected with the shell through a plurality of floating adjusting parts. The driving disk can drive the main clamping part to swing in the circumferential direction so that the head end of the main clamping part can rotate around the hinged point. The fixing base is driven by the main clamping part to conduct circumferential displacement within a preset circumferential floating range. The fixing base drives the auxiliary clamping parts to draw close to the workpiece or keep away from the workpiece. A braking mechanism connected with the shell and used for braking the shell is arranged on the periphery of the shell. The novel floating chuck has the advantages of being good in clamping effect and having a floating adjusting function.
