Fixing device for iron accessory machining

The utility model relates to the technical field of iron sheet machining, in particular to a fixing device for iron accessory machining, and aims to solve the problems that an existing fixing device cannot turn over a machining face and is inconvenient to fix in the background technology, according to the scheme, the fixing device comprises an operation table, and the outer surfaces of the two sides of the operation table are each provided with two symmetrically-distributed transverse plates; and supports are installed on the outer surfaces of one sides of the four transverse plates correspondingly, the same bottom plate is installed on the outer surfaces of the bottoms of the four supports, and electric sliding rails are installed on the outer surfaces of the bottoms of the four transverse plates correspondingly. The distance between the two fixing assemblies can be adjusted through the four electric sliding rails, the two air cylinders on the two C-shaped plates operate to drive the two clamping plates to c
