Fixing mechanism for reinforcing rib punching

The utility model relates to the technical field of reinforcing rib machining, in particular to a fixing mechanism for reinforcing rib punching. According to the technical scheme, the fixing mechanism mainly aims at solving the problems that an existing punching equipment fixing mechanism needs frequent manual operation of workers for fixing, generated waste is inconvenient to collect in the punching process, the cleanliness of the surrounding environment is easily affected after punching is completed, and follow-up punching work is hindered. A workbench and a support are installed on the top of the base plate, the working face of the workbench is in an inclined state, a groove is formed in the inclined face of the workbench, and conveying belt equipment is installed on the inclined face of the workbench. According to the automatic limiting device, the reinforcing ribs are automatically limited, the situation that the machining progress is affected by manual operation is avoided, meanwhile, the purpose of col
