Abstract

The invention discloses a large-span weak-rigidity gantry flexible hole forming device. A non-rigid supporting structure, a sliding beam and a lifting body are used to provide certain stability and the most basic movement mode for the hole forming device. According to the characteristics of hole forming between two reference holes of a tail end actuator, holes are formed in the local position of ahole forming region, wherein the local position is a region between the two reference holes for aligning of the hole forming tail end actuator, and free movement in directions X / Y / Z / A / B can be achieved when hole forming is carried out within the region. It is ensured that the hole forming device has enhanced local stability and accurate hole making precision in the field of hole forming. Regionalcustomization of the hole making region is realized according to the appearance size of each large part of an airplane and a hole making region, and various early-stage investment caused by traditional gantry type hole making is saved.

Description

technical field

[0001] The invention relates to the field of hole making of large aircraft parts in the aviation manufacturing industry, in particular to a rapid and precise hole making technology and a hole making device for large parts such as aircraft wings. Background technique

[0002] At this stage, the hole making method for large aircraft parts such as wings generally adopts the gantry hole making method. There are two forms of gantry drilling: one is the form of the overall movement of the gantry frame and the end effector. This type of gantry is an integral rigid frame. The weight of the moving gantry along the span direction becomes larger, the starting inertia is large, and the movement accuracy and efficiency are improved. low, poor stability, and high overall cost; another structural form is to set up foundation walls on both sides, and the upper frame of the gantry moves, and the cost will be greatly reduced by using the rigid frame on the upper part of the ga...

Embodiment Construction

[0012] Referring to the accompanying drawings, the present invention is a device for realizing large-span gantry-type flexible drilling.

[0013] From figure 1 In the middle view, the supporting structure 1 and the sliding beam 2 are non-rigid bodies, which only provide a certain stability support for the mechanism. The two supporting structures 1 stand opposite each other, the sliding beam 2 spans the two supporting structures 1, and the lifting column 3 is fixed On both sides of the fixing seat 4, the fixing seat 4 is driven to move up and down in the vertical direction.

[0014] From figure 2 In the middle view, the two support structures 1 include a support body 5 and a square rail 6, the square rail 6 is installed on the top end surfaces of the two support bodies 5, the sliding beam 2 is a frame structure, spanning the two support bodies 5, and the bottom Both ends are provided with pulleys 7 that cooperate with the square rail 6, and can slide along the support body 5...
