Title: WELDING JIG FOR SHEET METAL
Abstract:
A welding jig for a sheet metal comprises an installation plate (11), a position-limiting mechanism, and a welding protection mechanism. The position-limiting mechanism comprises a first positioning plate (12), a second positioning plate (13), and an abutting member (14). The first positioning plate (12) and the second positioning plate (13) are fixed to the installation plate (11) and perpendicular to each other. The welding protection mechanism comprises an L-shaped protection plate (15). The protection plate (15) comprises a protection portion (151) and a connection portion (152) which are perpendicular to each other. A welding escape hole (a) matching a welding region is arranged at the protection portion (151). A lower end face of the connection portion (152) is hinged to a side surface of the installation plate (11). A first magnet (16) is installed at the lower end face of the connection portion (152). A second magnet (17) is installed at an upper end face of the installation plate (11). When a protection cover rotates to attach to a weld face of a sheet metal, the first magnet (16) and the second magnet (17) attract and attach to each other. The jig securely positions a sheet metal while protecting a non-welding region of the sheet metal, thereby preventing formation of welding slag around a welding region of the sheet metal, and improving welding quality.
