The utility model discloses use simple structure compactness, convenient operation swift, use safe and reliable, accord with work piece characteristics etc. as the primary objective, designed a cast iron knuckle anchor clamps. The main design concept of the utility model is as follows:

1. and (5) a standard unification principle. Namely, the clamp reference and the workpiece reference are ensured to be uniform, a stable coordinate relation with a machine tool is kept, and the positioning error caused by the non-conformity of the reference is eliminated.

2. The principle of combining continuous effective positioning and incomplete positioning. When the continuous and stable positioning of the workpiece is ensured, the clamp structure is opened as far as possible by adjusting the auxiliary clamping in the direction of the residual degree of freedom, so that the clamping mechanism can be simplified, the clamping force is reduced, the surface to be processed is fully exposed, and the interference of the processing process is avoided.

3. And controlling the deformation minimum principle. The rigidity of the clamp is ensured, the workpiece is stably installed, the stress is uniform, the clamping is reliable, and the deformation generated by the clamping force due to the cutting force is minimum.
