Abstract

The invention discloses a clamping device for machining the outer circle of an end-toothed disc of a propeller shell. The clamping device comprises a base, a supporting base, a first mandrel, a second mandrel, a positioning cone and a pressing block. The supporting seat is used for supporting the first mandrel and the second mandrel, the pressing block is arranged at the top of the supporting seat and used for pressing the first mandrel and the second mandrel, the positioning cone is movably connected to the first mandrel and the second mandrel, a positioning part is arranged on the inner side of the positioning cone, and the positioning part can be inserted into a propeller sleeve on a propeller shell and matched with a conical hole of the propeller sleeve. The first mandrel and the second mandrel on the outer side of the positioning cone are provided with locking nuts, the locking nuts are in threaded connection with the first mandrel and the second mandrel respectively, and when the positioning part of the positioning cone is inserted into the taper hole of the oar sleeve, the locking nuts are used for locking the positioning cone; according to the clamping device, stable clamping of the propeller shell can be achieved, and the size of the outer circle of the machined end-toothed disc is accurate and reliable.
