The present disclosure relates to the technical field of target material
processing, and one embodiment of the present disclosure provides a clamping device for
machining a
metal flat target material, which comprises a disc holder and a plurality of fixing legs, the fixing legs are arranged on the bottom of the disc holder, a supporting disc is fixed on the surface of the disc holder, a clamping
assembly is arranged on the disc holder and the supporting disc, a bottom supporting
assembly is arranged on the disc holder, the clamping
assembly comprises a ring-shaped seat, a
rotating disc is slidably connected to the ring-shaped seat, an external gear is arranged on the bottom of the
rotating disc, a driving gear driven by
electricity is arranged on the upper surface of the disc holder, the driving gear is engaged with the external gear, a plurality of pushing grooves are formed in the surface of the
rotating disc, a plurality of clamping seats are arranged on the supporting disc, a plurality of long holes are formed in the surface of the supporting disc, the positions and the number of the long holes are matched with those of the pushing grooves, a guide rod is arranged in each long hole, and each clamping seat is slidably sleeved on the guide rod. Through the above technical solution, the technical problem that quick positioning and clamping cannot be realized in the prior art is solved.
