Problems solved by technology

But generally speaking, domestic aircraft assembly is still mostly in the stage of manual assembly using traditional frames. Digital drilling and assembly have not yet penetrated the overall assembly process of the aircraft. The automatic assembly system for component docking is still blank. The mobile production line technology based on the concept of lean manufacturing still in the exploratory stage

Embodiment Construction

[0051] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0052] See Figure 1A , Figure 1B The invention consists of five modules: a screw feed module 1, a binary angle adjustment mechanism 2, a compacting and sucking module 3, a drilling module 4, and a sensor module 5. The system needs to return to zero before drilling; then the laser ranging sensor in the sensor module 5 measures the normal vertical to the hole-making point; the binary angle adjustment mechanism 2 adjusts the posture of the end of the actuator; the chip suction module 3 is compressed The aircraft skin is compressed, and the dust suction device is turned on; the screw feed module 1 drives the drilling module 4 to make holes on the aircraft skin.

[0053] (1) Lead screw feed module

[0054] See Figure 2A with Figure 2B As shown, the screw feed module 1 includes: a screw drive motor 101, a timing belt 102, pulleys 103A to C, rolling bearings 104A to L,...

Abstract

The invention provides an aviation hole-forming robot end effector which is suitable for plane skin drilling and can be used for automatically adjusting the attitude. The end effector comprises a leading screw feeding module, a binary angle adjusting mechanism, a compacting chip-absorbing module, a drilling module and a sensor module. The leading screw feeding module mainly comprises a leading screw driving motor, a synchronous transmission component and a dual-ball leading screw and is used for realizing feeding motion of drilling; the binary angle adjusting mechanism mainly comprises a stepping motor, a transmission gear, a wedge-shaped turn table and a spherical hinge and is used for realizing the automatic adjustment of the tail end attitude; the compacting chip-absorbing module mainly comprises a cylinder, a pressing cylinder, a cylinder connecting rod and a compacting head and is used for realizing compaction of a skin and the absorption of metal drill chips; the drilling module mainly comprises a drilling servo motor, a transmission shaft, a drill chuck and a drill bit and is used for realizing high-accuracy drilling; and the sensor module comprises a proximity sensor and a laser distance-measuring sensor and is used for realizing zero addressing and limiting of the movement of a main shaft, and the measurement of the normal line of a drilling point.

Description

Technical field [0001] The invention relates to automatic hole making technology and attitude adjustment technology, in particular to an air hole making robot end effector suitable for automatic adjustment of attitude and hole making of aircraft skins. Background technique [0002] Assembly is a key link in the aircraft development process. At present, the aircraft assembly workload accounts for about 30% to 45% of the entire aircraft manufacturing workload, and the main connection method is drilling and riveting (drilling). However, traditional manual drilling has many shortcomings. Its workload is large, the drilling efficiency is low, the quality of the hole is difficult to guarantee, and the labor and material costs in mass production are high. Therefore, automated hole making technology is an important application and research direction in modern aircraft assembly. The robot automatic hole making has good flexibility and high adaptability to the workpiece, ensuring the hol...
