Clamping auxiliary device for bolt fixing plate production and machining

The utility model relates to the technical field of bolt fixing plate production, in particular to an auxiliary clamping device for bolt fixing plate production and processing, which is characterized in that materials are placed at the top ends of a plurality of groups of supporting plates, are clamped by two groups of clamping plates through rotation of two groups of rotating handles and transmission of two groups of lead screws, and then are processed by processing equipment. Dust and particulate matters generated during processing fall among multiple groups of supporting plates, and are discharged into a material receiving box through the inclined surface of the processing table, so that the influence of the dust and the particulate matters on the surrounding environment and the body health of workers is reduced, and the practicability of the equipment is improved; comprising a workbench, a machining table, a plurality of supporting plates, a material receiving box, two fixing bases, two side plates, two l
