Abstract：Based on the traditional processing technology of soft claw， this paper designs a soft jaw turning clamp fixtured by self inertial force with the application of Archimedes spiral principle and by increasing the spiral curve vector radius. Its design method， structure construction and application method are introduced. Practical implementations show that the designed clamp is flexible for operation， highly precise in processing， which effectively improves the positioning parts base and processing quality.
