Metal rod taking mechanism for machine tool machining

The invention discloses a metal rod taking mechanism for machine tool machining. The metal rod taking mechanism comprises a fixed supporting plate. In the using process, metal rods needing to be used and machined are placed in a first conveying groove, and due to the fact that the first conveying groove is obliquely formed by 45 degrees, the metal rods can roll to the bottom end of the first conveying groove to be stacked; then, under the action of a uniform distribution conveying disc rotating at a constant speed, uniform and stable conveying is carried out between a second conveying groove and a limiting groove formed in a conveying supporting plate, a first partition limiting plate and a second partition limiting plate, and the metal rods are discharged into a machining machine through an output supporting plate; when metal rods with different diameters are conveyed, only one metal rod is allowed once to pass through a space formed by the limiting groove and the second conveying groove by adjusting and con
