Precision machining tool and method for integral ribbed wallboard

Abstract

The invention discloses a precision machining tool and method for an integral ribbed wallboard, and particularly relates to the field of aluminum alloy machining. The precision machining tool for the integral ribbed wallboard comprises a surface milling area and a vacuum storage tank, wherein a downward pressing sucker and an upward pressing sucker are arranged on the two sides of the surface milling area respectively; and a vacuum pump is arranged on one side of the vacuum storage tank. According to the precision machining tool and method for the integral ribbed wallboard provided by the invention, steel formworks are machined according to the boundary dimensions of different wall plates, a set of vacuum suction cup device is additionally arranged between the steel formworks and a bottom plate, and a plurality of rectangular suction cups are adopted, so that enough suction force can be guaranteed, and the enough attachment degree between the bottom plate and the suction cups can be met; the suction cups are pressed downwards to integrally adsorb the wallboard, and more than one ton of gravity acts on an aluminum plate, so that the surface milling area can meet the machining requirement, the milling operation is completed section by section by adopting a numerical control milling machine according to the plate length, and the precision requirement of 1.5 mm + / -0.2 mm can be met by measuring the surface milling thickness through an off-line ultrasonic thickness gauge.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy processing, more specifically, the invention relates to a precision machining tool and method for an integral ribbed wall plate. Background technique [0002] The overall ribbed panel can be made of a variety of typical aging aluminum alloys, all of which have high specific strength, high specific stiffness and good processing performance. Various extruded aluminum alloy integrally extruded panels are used in aerospace, aerospace, Various cutting-edge fields such as shipbuilding. The extruded wall plate tube is formed as follows after cutting, annealing, flattening, secondary annealing, stretching, etc. Figure 4 in the siding. [0003] The thickness of this wallboard is about 6-10mm, and it must be machined to mill the lower surface to 1.5mm±0.2mm. Processed siding such as Figure 5 shown. After the panel is processed through the above multiple processes, there are large deviations in ...

AI Technical Summary

Problems solved by technology

After the panel has been processed through the above-mentioned multiple processes, there are large deviations in the flatness, thickness, and height of the rib platform, etc., and it is difficult to guarantee a machining accuracy deviation of ±0.2mm during the milling process.
