Design of the Precision Detection Device for the Key Dimension of Bending Mold

摘要

The key to guarantee bending mold interchangeability is the precise detection of the cutting edge angle, symmetry and the distance from its center to the fitting surface of CNC bending mold. According to the features of the Key Dimension of the Bending Mold (KDBM), it is detected using a 3-DOF mechanical arm connected in series. The mechanical arm has a horizontal DOF, a vertical DOF, and a rotational freedom of the gauge head which is placed at the end of the mechanical arm. The Precision Detection Device (PDD) for KDBM that we have designed has high accuracy, good stability and rapid response.
