A Multifunctional Mechanized Device For Welding Of Curved Profiles

Abstract: The invention relates to a multifunctional mechanized device for welding of curved profiles, comprising : a linear track allowing a linear motion to a carriage head at a pre-determined speed, one end of the carriage head provided with a rectangular plate; a hollow-tube (4) fillet welded with the rectangular plate with a helical spring (5) inserted into the hollow tube (4); a round bar (6) inserted into the hollow tube (4), each of the round bar and hollow tube (4,6) having slots to allow locking of each. Other upon compression and fixed by a locking pin (7); the assembly of the hollow tube and the round bar (4,6) caused to move using the spring (5) in a direction perpendicular to the linear carriage (2), said motion further having linear motion perpendicular to said linear track (1); a roller bearing (8) connected to the end of the round bar (6) which follows the path formed on a profiled template (10); and an extension rod (9) with an X-Y slider and movable in both linear direction, wherein a welding torch is connected to the slider by a clamp to carry-out an accurate welding on curved linear profile.
