Processing method for curved compound metal wallboard hole

Abstract

The invention relates to a processing method for a curved compound metal wallboard hole. Automatic titanium alloy compound wallboard drilling equipment provided with a camera is included. The drillingequipment is fixed to the front end of a robot arm. The processing method is characterized by comprising the steps of additionally arranging a special processing program for the automatic drilling equipment in a robot control system; setting NC parameters and a macroprogram CLAMP / UNCLAMP; carrying out logic edition on a PLC program; and executing a processing step on the curved composite metal wallboard hole. According to the method, the normal direction of the wallboard can be aligned according to a simulated program, so that it is ensured that a processed hole is vertical to a surface; thesize of the pressure of a compaction mechanism can be adjusted according to the condition of the processed wallboard, so that it is ensured that a workpiece does not affect the hole processing qualityas a result of too large or small pressure; and a drilling-reaming compound tool can finish high quality hole processing at one time, and a peck drilling method can avoid long chips in the processingcourse. The method processes the hole at one time by adopting the compound tool, so that the method solves the problems of unstable processing quality of the compound wallboard hole, inaccurate positioning, low efficiency, accumulated chips and the like.

Description

technical field [0001] The invention relates to the field of processing in the aircraft industry, in particular to a method for processing a hole in a curved surface composite metal wall plate. Background technique [0002] There are many composite panels in the aircraft manufacturing process, and the processing requirements for assembly holes are very strict in the aircraft production process. Due to the large size of the panels and the curved surface structure, the thickness is between 4-6mm. Manual processing is the main method, and the processing quality and stability of the holes cannot be guaranteed during the processing process, and the problem of unqualified hole processing often occurs; at the same time, the processing accuracy of such holes is high, and manual processing needs to be divided into two processes: drilling and reaming , so that the manufacturing time of the siding is longer, thereby increasing the manufacturing cost of the enterprise. Developed specia...
