Multi-gear linkage clamping device for aerospace conduit cutting and blanking equipment

The multi-gear linkage clamping device comprises a first mounting plate and a plurality of clamping plates, a first through hole is formed in the center of the first mounting plate, the multiple clamping plates are arranged around the first through hole, one end of each clamping plate is rotationally connected with the first mounting plate, and the other end of each clamping plate is rotationally connected with the second mounting plate. The other ends of the clamping plates are close to the axis of the first through hole, and a clamping space is defined by the other ends of the multiple clamping plates; the multiple clamping plates move synchronously, so that the clamping space is enlarged or reduced; at least two clamping plates form a clamping set, and the distances between the multiple clamping plates of the same clamping set and the first mounting plate are different. Thus, the clamping device can clamp various pipe fittings of different specifications and can clamp any position of the guide pipe, when t
