APPARATUS FOR INDUCING AIXAL FORCE OF HIGH STRENGTH BOLT AND METHOD OF INDUCING AXIAL FORCE USING THE SAME

摘要

The present invention provides a power input unit to which power is input, an axial force input unit to which an axial force of a high power bolt is input through a load cell mounted on the high power bolt, and a power measuring unit for measuring the accumulated amount of current input through the power input unit; A data analysis unit that analyzes the current measured by the measuring unit and the axial force input from the axial force input unit, and the target current supplied to the electric wrench to introduce the target axial force to the high-strength bolt using the data analyzed by the data analysis unit It relates to a high-strength bolt axial force introduction device comprising: a target value setting unit and a power output unit connected to an electric wrench to supply a target current calculated by the target value setting unit. According to an embodiment of the present invention, the target current is input to the electric wrench so that the high-strength bolt can be fastened with the target axial force.
