Problems solved by technology
However, there are problems with the clamping and processing support of the skin parts in skin milling. Because the skin parts are complex in shape and large in size, they are very easy to deform, and it is difficult to clamp in a vertical state. It is necessary to use a crane or a car crane.

The invention provides a moving and turning-over mechanism for aircraft skin mirror image milling equipment. The moving and turning-over mechanism comprises a moving device, a turning-over tool and alocking mechanism. The turning-over tool comprises a worktable, a worktable bracket, a turning-over power device and a turning-over shaft. The worktable bracket comprises a supporting frame and a base; the supporting frame is connected to the upper portion of the base; the supporting frame is of a frame-type structure matched with the worktable; the bottom side of the worktable is connected to thebase through the turning-over shaft in the mode of being capable of rotating around the turning-over shaft; and the turning-over power device is mounted on the base and movably connected with the worktable. According to the moving and turning-over mechanism for the skin mirror image milling equipment, the function that a part is horizontally mounted and clamped firstly, and then turned over to beupright is achieved, the requirement of skin mirror image machining can be met, and milling and supporting of mirror image machining are achieved through one-time clamping.
Description
technical field [0001] The invention relates to the technical field of mirror milling, in particular to a moving turning mechanism used for aircraft skin mirror milling equipment. Background technique [0002] At present, the overall structure and large-sized thin-walled parts are widely used in aircraft. The overall structure and large-sized thin-walled parts are complex in structure, very easy to deform, and require high dimensional accuracy, making it difficult to manufacture. In addition, the shape of large thin-walled parts is mostly related to the aerodynamic performance of the aircraft, and the peripheral contours and other parts have complex assembly and coordination relationships, making assembly very difficult. [0003] Following the traditional aircraft skin chemical milling process for many years, from the analysis of processing accuracy, using the chemical milling process, the parts need to be clamped at least twice, and repeated clamping will affect the accurac...
