Embodiment Construction
[0022] Embodiment: Part 1 in the figure is the device for fixing the fixture on the upper cantilever of the hydraulic press, part 2 is the fixed convex seat of the mounting seat, part 3 is the female mold of the fixture, part 4 is the working curved surface of the simulated welding part, and part 5 is the fixture The male mold, the male mold can rotate circumferentially in the support platform of the hydraulic press, and the part 6 is the spring used in the fixture, which is used to give an upward tightening force to the top tight convex seat 2, so as to ensure that the mounting seat does not collapse downward during the welding process , Part 7 is the male mold fixing device of the lower cantilever assembly fixture of the hydraulic press. The specific profile of the fixture can be adjusted according to the main profile of the parts to be welded, and the shape and size of the opening of the fixture can also be adjusted according to the shape and size of the specific parts.

The invention discloses an aero-engine installation base welding tool and method. The tool comprises a male die (5) and a female die (3); the matched face of the male die (5) and the female die (3) and a to-be-welded part are identical in outer contour shape; a welding window is formed in the center of the female die (3); a hole is formed in the center of the male die (5), and a jacking boss (2) is installed through a spring (6); the jacking boss (2) is located below the welding window. According to the tool, the problems that an existing large thin-wall aviation part mounting base cannot be welded in a limiting state and the deformation of the mounting base after welding is serious are solved. The small simple welding tool is adopted and matched with a common hydraulic machine in use, andthe tool is easy to operate, wide in application range, high in welding efficiency and good in deformation control effect.
Description
technical field [0001] The invention relates to a welding positioning tool and a welding method thereof. Background technique [0002] In aviation, all engines involve welding of mounts. Mounting seats on aviation parts are mainly used to assemble various pipelines, observation devices, etc. The stability and reliability of the processing quality of the mounting seat determine the service life of the engine, and even endanger the safety of the aircraft. In the process of welding the mounting seat, some parts have good structural rigidity and small deformation during welding. However, most of the parts have poor rigidity and large deformation during welding, which leads to the fact that the later machining of the mounting seat cannot meet the design and use requirements. In the past, the process of welding mounting seats for aero-engine parts was as follows: use large and heavy fixtures to position first, and then weld in a free state, which is very easy to deform during t...
