Cutting device for steel structure machining

The invention relates to the technical field of steel structure machining, in particular to a cutting device for steel structure machining, which comprises a worktable and a fixing block, the fixing block is fixedly mounted at the upper end of the worktable, a cutting opening is formed in the side wall of one end of the worktable, a guide plate is fixedly mounted at one end of the fixing block, and a limiting groove is formed in the upper end of the fixing block. An outlet is formed in the lower side of the side wall of one end, a pushing opening is formed in the lower side of the side wall of the other end, a movable plate is slidably connected into the limiting groove, and a pushing plate is slidably connected into the pushing opening; one end of a whole steel structure is straightly inserted into a limiting groove and makes contact with the side wall of the lower end of a movable plate, an air cylinder pushes a mounting plate, a bottom plate and an anti-skid pad to move downwards synchronously, the steel s
