Numerical control lathe fixture

The utility model relates to the field of clamps, in particular to a numerical control lathe clamp which comprises two supporting assemblies, a first fixing structure and a second fixing structure. The first fixing structure and the second fixing structure are installed on the outer walls of the tops of the two supporting assemblies respectively. The first fixing structure and the second fixing structure each comprise a main shaft, a fixing cylinder welded to the outer wall of one end of the main shaft, electric ejector rods installed at one end of the inner wall of the fixing cylinder at equal intervals, a fixing frustum installed at one end of each electric ejector rod, and a fixing groove formed in the center of the fixing frustum. The movable holes are equidistantly formed in the outer wall of the fixed frustum and located at one end of the fixed groove. The electric ejector rod is started to push the fixed frustum to move through the fixed barrel, the fixed frustum, the sliding barrel and the electric ej
