Clamping direction adjusting mechanism of numerical control machine tool

The invention provides a clamping direction adjusting mechanism of a numerical control machine tool, and belongs to the technical field of machine tool clamps. Comprising a bottom plate, and a supporting component used for supporting a to-be-machined part, a clamping component used for being matched with the supporting component to clamp the to-be-machined part and a driving component used for driving the supporting component to slide and enabling the supporting component to achieve overturning of the to-be-machined part under matching of the clamping component are installed on the bottom plate. Through the arrangement of the clamping component, the supporting component and the driving component, after the upper surface of the to-be-machined part is machined, the to-be-machined part can be deflected, the bottom of the deflected to-be-machined part is supported, the stability of the to-be-machined part during new upper surface machining is guaranteed, the structure is simple, use is convenient and fast, and th
