Single side soft absorption type automatic drilling robot

Abstract

The invention provides a single side soft absorption type automatic drilling robot which is applicable to operation such as hold drilling, reaming, dimpling and the like at wings and fuselage parts, and the machining for materials which are hard to machine such as titanium alloy (Ti) and composite materials (CPRF) is realized. The robot is fixed at an expected machining area by using a gas source provided by a vacuum generator and by using a vacuum chuck; and a soft track can adapt to different machining curves according to different curvature. The positioning of a drilled hole and the adjustment of the verticality of a drill bit are realized according to a drill plate. A pneumatic main shaft is adopted as the main shaft of the robot; and in combination of an ultrasonic vibration machining technology, the quality and efficiency of the machining are improved; the machining difficulty is reduced; the current detection at a feeding direction can be carried out in real time during the hole making process; and the protection and precise control for the machining process are realized.

Description

technical field [0001] The present invention generally relates to automatic hole-making technology and robot technology, and more specifically, the present invention relates to vibration hole-making technology, a hole-making robot with a single-side flexible track, and a drilling mold automatic positioning and attitude adjustment system. Background technique [0002] The requirements for the safe service life of modern aircraft are increasing day by day. The service life of mainline aircraft is required to reach more than 50,000 flight hours respectively. The fatigue life of many advanced aircraft in the world has reached 80,000 flight hours. Now the main connection method used in aircraft structure is mechanical connection. There are approximately 1.5 to 2 million connecting holes on a large aircraft, and the load carried by the aircraft is transmitted through the connecting parts, resulting in stress concentration at the connecting parts. According to statistics, 70% of ai...

Problems solved by technology

However, there are many problems in my country's large aircraft manufacturing: low degree of automation, slow processing speed of connection holes, poor reliability; low precision; low degree of intelligence, aircraft assembly holes mostly rely on manual tool hole making, and the overall accuracy level is H9 , the international level has reached H8, which seriously restricts fatigue resistance and safe service life

The quality stability of my country's aircraft is poor and the efficiency is low, and there is a big gap with foreign countries. The reason is that my country's assembly and hole making technology and equipment technology level is relatively low
