Multiple-cavity special-shaped double-layer thin-wall section pipe fitting correcting robot

Abstract

The invention relates to the field of correcting and processing of multiple-cavity special-shaped double-layer thin-wall section pipe fittings for aviation, and discloses a multiple-cavity special-shaped double-layer thin-wall section pipe fitting correcting robot. The pipe fitting correcting robot comprises a machine frame, a fixing assembly, a moving assembly and a pressure suction assembly, wherein the pressure suction assembly comprises a first hydraulic cylinder, a first disc rack, a second hydraulic cylinder and a second disc rack, the fixed end of the first hydraulic cylinder is connected with the bottom of a first rack body, a piston rod of the first hydraulic cylinder is connected with the top of the first disc rack, the fixed end of the second hydraulic cylinder is connected with the top of the second rack body, and a piston rod of the second hydraulic cylinder is connected with the bottom of the second disc rack. According to a double-layer shell shaping device, the upper and lower pressure suction assemblies are used for shaping the upper-layer surface and lower-layer surface of a double-layer shell correspondingly, and a sucker or a pressure plate can be replaced so as to solve the problems that the surface of the material is recessed and raised.

Description

technical field [0001] The invention relates to the field of rectification and processing of multi-cavity special-shaped double-layer thin-walled section pipe fittings for aviation, and in particular to a multi-cavity special-shaped double-layer thin-walled section pipe correction robot. Background technique [0002] At present, after the multi-cavity special-shaped double-layer thin-walled section pipe fittings for aviation are extruded, due to the uneven distribution of materials, the shape and size tolerance after forming seriously do not meet the design requirements, and the curvature of the upper and lower layers is different. The traditional orthopedic method is likely to cause larger parts. The internal stress of the material leads to the formation of protrusions and depressions on the surface of the material, which does not meet the design requirements and requires secondary processing. [0003] Currently, the shaping of the formed shell is usually done manually. Fo...

AI Technical Summary

Problems solved by technology

For surface protrusions, for example, use a rubber hammer to gently tap the protrusions, but for depressions, due to the small gap in the middle of the double-layer shell, ordinary tools cannot complete the shaping of the depressions on the surface of the material, and manual shaping time Long and inefficient, increasing the cost of labor, thereby increasing the burden on enterprises
