Abstract

The invention discloses a posture adjusting and positioning device for assembling an external culvert casing. The posture adjusting and positioning device comprises a vertical adjusting assembly, a posture adjusting assembly, a clamping assembly and an auxiliary supporting assembly, wherein the vertical adjusting assembly comprises a base, a sliding rail, a lead screw, a turbine box and a verticaldriving element; the posture adjusting assembly comprises a pitching driving element, a transverse rotation driving element, a first RV speed reducer, a second RV speed reducer, a sliding table and aswing joint; the clamping assembly comprises a supporting disc and a pressing device; and the auxiliary supporting assembly comprises a supporting arm and a flat bracket. The posture adjusting and positioning device has the beneficial effects of being high in transmission precision, high in stability and the like, the problems that during manual assembling, posture adjusting and positioning are inconsistent, and stability is poor are solved, the assembling, positioning and posture adjusting precision of the external culvert casing is improved by 10 times or above, and that the production efficiency is improved by 5 times or above is predicated. The posture adjusting and positioning device is applied to the field of aerospace machinery.

Description

technical field [0001] The invention relates to the field of manufacture and assembly of aero-engine outer casings, in particular to an attitude adjustment and positioning device for assembling outer casings. Background technique [0002] In the assembly of the outer casing of the aero-engine, pressure riveting is one of the most important connection methods, which occupies the main workload of the assembly of the outer casing. The quality of the pressure riveting of each hole depends largely on the The positioning accuracy of the external culvert casing when the hole position is riveted. At present, the assembly of aero-engine casings in my country is still in the mixed operation mode of manual and simple semi-automatic equipment. One riveting station requires three workers to cooperate with simple tooling brackets and semi-automatic riveting machines, including manual loading and manual adjustment of tooling. Fixtures, so as to adjust the position and posture of the pre-ri...
