AUTOMATIC CUTTING DEVICE OF WELDING GROOVE AND EXCESS WELD METAL DEPOSIT AND THE LIKE IN COLUMN BODY OF BOX STRUCTURE

摘要

PURPOSE: To carry out the removal of excess weld metal deposit generating in a diaphragm assembly in the column body of a box structure and the preparation of a welding groove at an edge unprepared part in order automatically by moving a rotary cutter blade. ;CONSTITUTION: A gate shape frame 16 providing a running device 12 running freely along a work 6 on a rail 11 laid at a prescribed interval, a cutter unit 40 which is supported traversably by a beam 17 being supported liftably on the one side face crossing to the running direction of the gate shape frame 16 and also supported capable of advancing and retreating in a parallel direction with the work 6 and an electric control mechanism for controlling the operation of respective parts are provided. Further, the cutter unit 40 provides a cutter blade 46 rotating by the direct connection of a motor, an advance/retreat drive mechanism for controlling the cut in amount of the cutter blade 46 and the turning mechanism of a cutter head 45 which can turn the advance/retreat drive mechanism and the drive motor of the cutter blade 46 and change the cutting direction by the cutter blade 46 and set a cutting angle are provided.;COPYRIGHT: (C)1993,JPO&Japio
