The invention discloses a clamp used for eccentric drill bushing processing and a processing method for the eccentric drill brushing. A circular step through hole is formed in the upper end surface ofa cylindrical clamp body (1); the circular step through hole comprises a first circular hole and a second circular hole with the outer diameter smaller than that of the first circular hole; the axisof the circular step through hole is parallel to that of the cylindrical clamp body (1); and a vertical interval between the two axes is H. A to-be-processed eccentric drill brushing part (2) is accurately clamped on a special tool while the clamp is guaranteed to be accurately clamped on an internal grinding machine; and a proper grinding tool and proper parameters are selected for grinding parts. The clamp can realize small-batch processing, on common grinding equipment, of eccentric drill brushing parts, improves processing efficiency, and reduces processing cost of the parts. 本发明公开了种用于偏心钻套加工的夹具及偏心钻套的加工方法，圆柱形夹具体(1)的
