The invention discloses a clamp for simultaneously grinding crankshaft holes in parts in an RV reducer and a using method. A positioning fake pin is installed and sequentially penetrates a base plate, a bearing, a supporting flange, a transition plate, a first RV gear, a second RV gear and a center hole in the cover plate from bottom to top; the bearing and the supporting flange between the base plate and the transition plate are locked through a second compression bolt; the bearing and the supporting flange between the base plate and the transition plate, and the first RV gear and the second RV gear between the cover plate and the transition plate are locked through a first compression bolt; and the positioning fake pin is pulled out from the base plate, the bearing, the supporting flange, the transition plate, the first RV gear, the second RV gear and the center hole in the cover plate and then the crankshaft holes are ground. According to the clamp, the crankshaft holes in the first RV gear, the second RV gear, the supporting flange and the bearing in the RV reducer can be ground simultaneously, the consistency of the accuracy of the crankshaft holes with same coordinates is guaranteed, the machining time is short, efficiency is high, the assembling accuracy of the RV reducer is guaranteed, and the clamp has the good application prospect.
