Abstract

The invention provides an automatic moving type spiral hole milling manufacturing system. The automatic moving type spiral hole milling manufacturing system comprises an automatic moving mechanism composed of a crawling mechanism and a double-swinging platform. The crawling mechanism comprises an upper supporting plate, a lower supporting plate, bearings, a rotating shaft, a rectangular rotating plate, a first sliding rail, a first sliding block, a first drive device and three peripheral electric telescopic rods. The double-swinging platform comprises a first swinging shell, a second swinging shell, a first gear shaft, a third drive device, a second gear shaft and a fourth drive device. According to the automatic moving type spiral hole milling manufacturing system, the rotating shaft and a first screw pair are arranged between the upper supporting plate and the lower supporting plate of the crawling mechanism, random steering and horizontal moving of the crawling mechanism are achieved, and in addition, the hole machining position precision can be ensured through the double-swinging platform.

Description

technical field [0001] The invention relates to a digital assembly automatic hole-making system, in particular to an autonomously moving helical milling hole-making system. Background technique [0002] In order to meet the requirements of high life, high strength, sealing and anti-fatigue of modern aircraft, the lightweight automatic drilling system is gradually being extended to the assembly drilling of the fuselage because of its advantages in compromise between efficiency, flexibility and cost. At present, there are three types of typical light-duty automatic hole-making systems: automatic hole-making systems based on industrial robots, flexible track automatic hole-making systems, and autonomous mobile automatic hole-making systems. [0003] The automatic hole-making system of industrial robots uses general-purpose industrial robots to attach corresponding end-hole-making actuators. Although industrial robots have good flexibility, high precision and efficiency, and a w...
