Small-allowance 60-degree clamping wedge-shaped clamp for forging and casting

The utility model belongs to the technical field of numerical control machining of airplane forging and casting parts, and relates to a small-allowance 60-degree clamping wedge-shaped clamp for forging and casting parts. The fixture is simple to mount and fix and convenient to operate, adopts a 60-degree wedge-shaped structure for clamping, can meet the clamping requirement of small allowance, completely utilizes the effective allowance of a blank for clamping, is reliable in strength, and does not bring the problem of insufficient strength. The wedge-shaped structure mainly depends on wedge-shaped clamping force, the clamping effect in the transverse direction and the clamping effect in the vertical direction can be achieved through the wedge-shaped clamping force, the blank is transversely fixed and vertically tensioned, the whole clamping state is stable and firm, extra and redundant clamping stress cannot be generated, and stability of the product machining process is facilitated. The pressing plate is ad
