Abstract

The invention discloses a welding tool of a water inlet grating, and belongs to the field of machining tools. The welding tool comprises a base, an adjusting assembly, a bow positioning assembly and astern positioning assembly, wherein the bow positioning assembly is used for installing a bow mounting plate of the water inlet grating, the stern positioning assembly is used for mounting a stern mounting plate of the water inlet grating, the bow positioning assembly is slidably mounted on the base, the stern positioning assembly is fixedly arranged on the base, the adjusting assembly comprisesa screw rod and two positioning nuts, the screw rod is fixed on the base, the screw rod is in sliding fit with the bow positioning assembly, the two positioning nuts are in threaded fit with the screwrod, and the two positioning nuts are located on the two opposite sides of the bow positioning assembly respectively. According to the welding tool, the applicability of the welding tool can be improved.

Description

technical field [0001] The invention belongs to the field of processing tooling, in particular to a welding tooling for water inlet grills. Background technique [0002] The water jet propulsion device uses the reaction force of jet water to propel the ship. The water inlet grid is an integral part of the water jet propulsion device, which is installed at the inlet of the inflow pipe to prevent floating objects from entering the inflow pipe, and prevent the water jet propulsion pump from being blocked by floating objects. [0003] Common water inlet grilles mainly include bow mounting plate, stern mounting plate and grille strips, and the bow mounting plate and stern mounting plate are welded together by grille strips. Since the bow mounting plate and the stern mounting plate are special-shaped structural parts, special welding tooling is required for clamping, so as to avoid welding deformation of the water inlet grille during the welding process. [0004] However, due to...
