Publication number: 20090308624Abstract: Conventionally, as screw tightening axial force control, there is a control method such as a torque control method. The torque control method requires estimation of a torque coefficient, and has a problem that a calculated axial force value is an estimated value. An object of the present invention is to provide a method for directly controlling an axial force by calculating the axial force generated by an impact force by using an impact wrench. A 45-degree slant line is set from an origin O of orthogonal coordinate axes to be used for screw tightening axial force control, an impact progress point Hi generated by an i-th impact is detected on the 45-degree slant line, a length HSi of a line segment OHi is read, and an axial force value Fi after the i-th impact occurs is calculated by using the formula Fi=HSi×cos 45°. Another method for controlling the axial force by using impact information is also disclosed.Type: ApplicationFiled: August 28, 2007Publication date: December 17, 2009Inventors: Ryoichi Shibata, Yoshiyuki Nakagawa
