A Cutting Device for Uneven-surface-thickness Board Based on Premixed Abrasive Water Jet

摘要

The present invention discloses a cutting device for uneven-surface-thickness board based on premixed abrasive water jet, comprising an uneven-surface-thickness board workpiece and a two-dimensional machine tool table, and further comprising a C-shaped synchronous frame and an intelligent detecting device. An upper annular synchronous transmission chain set, a lower annular synchronous transmission chain set and a center power motor are arranged in the C-shaped synchronous frame, and the intelligent detecting device comprises an upper detector and a lower detector; the upper detector and the lower detector are each internally provided with a jet evenly-distributing hole, a stepped segment is arranged in the jet evenly-distributing hole, a stress test sensor is arranged in the stepped segment, and a spring and a guide column are sequentially mounted at the lower end of the jet evenly-distributing hole. According to the present invention, the standoff distance between the get gun and the board workpiece and the moving speed of the jet gun are adjusted according to the bending degree and the thickness of the workpiece, so that the jet energy residue is reduced, and the jet parameters of the jet gun are automatically adjusted in real time.
