Clamp special for turning eccentric shaft parts

The utility model discloses a clamp special for turning eccentric shaft parts, which comprises an eccentric sleeve and an elastic live center, wherein the front end of an eccentric shaft part to be machined is arranged in the eccentric sleeve and fixedly connected with a three-claw chuck through the eccentric sleeve, and the tail end of the eccentric shaft part to be machined is supported by the elastic live center. As being formed by a structure that the eccentric sleeve is matched with the center, the clamp special for the turning eccentric shaft parts can eliminate the theoretical calculation of the traditional gasket by operators, greatly reduce the technical requirement of the operators, guarantee the simple operation and the high precision when being turned, and realize quantity production. The center which is used for tightly supporting the parts adopts the elastic live center, thereby preventing the parts from moving, and guaranteeing the machining precision.
