Embodiment Construction

[0022] like figure 1 , figure 2 , Figure 4 As shown, the fully pneumatic flexible positioning and holding device for clamping the aircraft skin for automatic drilling and riveting includes an actuator 3 with a cylinder system and a moving shaft locking device, and a moving shaft 5 connected to the actuator 3 and Universal suction cup seat 6 installed on the moving shaft. The inner space of the cylinder 3, the moving shaft 5 and the piston 14 form a function similar to that of a cylinder. The direction of movement of the moving shaft 5 is changed by changing the air inlet, and the robot is used to stop it for precise positioning. Its adjustable range is more than 400mm, and has high positioning accuracy, which can meet the positioning and holding requirements of different types of skins.

[0023] Sucker 16 is housed on the sucker 7, and when sensor was not pressurized, air valve air intake volume was bigger, and moving shaft 5 moved fast;

[0024] The moving shaft locking...

Abstract

The invention discloses a positioning holder for automatic drill-riveting of aircraft skin, and particularly relates to a full-pneumatic flexible positioning holder, which comprises an actuating tube, a moving shaft, a universal sucker seat and a sucker, wherein the moving shaft is capable of moving in the actuating tube, and the universal sucker seat and the sucker are mounted at the top end of the moving shaft. A bottom plate for fixing the whole positioning holder, a moving shaft lock and a moving shaft buffer are mounted on the actuating tube, an interior space of the actuating tube, the moving shaft and a piston form a member similar to an air cylinder, and the movement direction of the moving shaft is changed by shifting an air inlet. A sensor is mounted on the sucker and can be used for controlling an air valve to change air intake to slow down or speed up the moving shaft. A flexible clamp capable of automatically shaping and adapting to different skins is formed by means of moving of the moving shaft and the sucker.

Description

technical field [0001] The invention relates to a positioning and holding device for automatic drilling and riveting of aircraft skin, in particular to a fully pneumatic flexible positioning and holding device. Background technique [0002] Aircraft skin, as a key part of the aircraft's aerodynamic shape, has complex shapes, large size ranges, low stiffness, and small production batches. The traditional processing method is to fix the skin on a rigid fixture, and then perform drilling and riveting. The work is labor-intensive, the drilling accuracy is low, and the riveting quality is poor. In recent years, in order to achieve precise and efficient drilling and riveting of the skin and improve manufacturing quality, foreign aircraft manufacturers have gradually adopted the CNC drilling and riveting process based on flexible tooling. Since the early 1990s, flexible tooling developed by foreign companies has been used by aircraft manufacturers such as Boeing, Airbus, and McDon...
