The invention discloses an assembly tool for laser welding, comprising a welding tool and an assembly positioning tool, wherein the assembly positioning tool and the welding tool are detachably installed; the welding tool is a rotatable welding tool, including a rotating mechanism and a positioning surface And the first positioning hole, the surface to be welded of the part can be turned to the laser welding robot through the rotating mechanism, the positioning surface is used to determine the shape of the part, and the first positioning hole is used to position the part during welding; the assembly positioning tool includes a parallel positioner, The lower end of the parallel locator is provided with a second positioning hole; the parallel locator is used to cooperate with the laser tracker, and the second positioning hole is used for positioning parts during assembly. The invention also discloses an assembly process of the assembly tool. The purpose of the assembly tool for laser welding and the assembly process thereof is to solve the problem that the existing aircraft intake and exhaust duct assembly tool and the laser welding tool are difficult to coordinate with each other.
Description
technical field [0001] The invention belongs to the technical field of assembly tooling, and in particular relates to an assembly tooling for laser welding and an assembly process thereof. Background technique [0002] In the laser welding of the aircraft intake and exhaust duct wall panels and the assembly of components, tooling is required for positioning and clamping to ensure that the parts are in the correct position and posture before connection. The traditional laser welding tooling and component assembly tooling are two separate sets of tooling, which need to be removed from the welding tooling after welding, and then sent to the component assembly tooling for re-positioning. Because the magnitude and direction of geometric dimension changes caused by welding are difficult to predict, it is usually difficult to match the parts transferred to the assembly process with the assembly tooling to complete the work of positioning on the shelf, especially on titanium alloy p...
