Clamp used for vertical roller craft equipment of universal mill of numerical control vertical machine tool

The utility model relates to a clamp used for vertical roller craft equipment of a universal mill of a numerical control vertical machine tool, which solves the shortcomings that the turning of the working surface of the existing vertical roller can not be completed by one step, the machining time is long, the machining quality is difficult to be guaranteed, the operation efficiency is low, and the like by the following measures: the clamp used for the vertical roller craft equipment of universal mill of the numerical control vertical machine tool is characterized in that the clamp consists of a U-shaped top plate 1, a sidestep plate 2 which is symmetrically connected with two sides of the U-shaped top plate 1, a connecting hole 3 and a hoisting lug 4 which are arranged on the U-shaped top plate 1, and a connecting hole 5 which is arranged on the sidestep plate 2. The clamp can complete turning the vertical roller of the universal mill by one step, the smoothness of the turned vertical roller can achieve the
