Abstract

The invention relates to a welding fixture, in particular to an automatic clamping and welding fixture with a correction function suitable for exhaust fume collecting hoods of multiple specifications.The automatic clamping and welding fixture comprises a platform, wherein the platform is used for accommodating an exhaust fume collecting hood with a front folded edge, a left folded edge and a right folded edge. The automatic clamping and welding fixture is characterized in that the platform is composed of a main platen and a side platen, and a driving structure used for driving the side platento slide left and right is arranged at the bottom part of the main platen; a left rear pressing block, a left side pressing block and a front middle baffle plate are arranged on the main platen, theleft rear pressing block is driven by means of a left rear cylinder, the left side pressing block is used for making contact with the side surface of the left folded edge, and the front middle baffleplate is fixed to the front portion of the main platen and used for making contact with the middle portion of the front folded edge; a right rear pressing block and a right side pressing block are arranged on the side platen, the right rear pressing block is driven by means of a right rear cylinder, and the right side pressing block is driven by means of a right side cylinder; and an upper cylinder is arranged above the main platen, and a correction pressing block is fixed to a piston rod of the upper cylinder. The automatic clamping and welding fixture can be used for welding the exhaust fumecollecting hoods of different specifications, can further ensure the flatness of the front folded edge of the exhaust fume collecting hood after welding, and is beneficial to later assembly.

Description

technical field [0001] The invention relates to a welding auxiliary device, in particular to an automatic clamping welding fixture suitable for multi-standard fume collecting hoods and having a correction function. Background technique [0002] The fume collecting hood is the main part of the range hood. It is generally formed by stamping and bending thin steel plates and then welded. The parts where the front hem, the left hem and the right hem are in contact with each other are fixed together by laser welding. For example, a Chinese utility model patent "A Seamless Welding Range Hood" whose patent number is ZL201320636234.6 (announcement number is CN203628752U) discloses such a smoke collecting hood. The quality of welding directly affects the quality of the fume collecting hood, because the fume collecting hood is made of thin steel plate, and the front fold, left fold and right fold are relatively long and narrow, if the positioning is not good during welding, it is eas...
