Material clamping mechanism of spark numerical control wire cutting machine

The utility model discloses a material clamping mechanism of a spark numerical control wire cutting machine, which relates to the technical field of material clamping of wire cutting machines and comprises a fixed platform, a positioning component is movably mounted in the fixed platform, one end of the positioning component is movably connected with a clamping component, and the positioning component comprises a butt joint rod and a positioning frame. According to the material clamping mechanism, the clamping assembly and the positioning assembly jointly form the material clamping mechanism, the positioning assembly is used for determining the position of a material, the clamping assembly can be synchronously driven to rotate in the position determining process, the material is clamped while the material is fixed, and therefore the material clamping efficiency is improved. And the moving direction of the butt joint rod is kept opposite to the clamping assembly and the positioning assembly, so that friction b
