Embodiment Construction
[0056] The automatic processing method for aircraft structural reinforcements of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0057] Such as figure 1 An automatic processing method for an aircraft structural reinforcement is shown, and its implementation process includes the following steps:
[0058] Step S1, obtain the data of the area to be strengthened by the aircraft through the handheld laser scanner, specifically including:
[0059] Step S101, using a hand-held laser scanner to obtain the point cloud data of the inner surface of the aircraft to be reinforced;
[0060] Step S102, preprocessing and clipping the point cloud data of the inner surface, so that the shape of the point cloud of the area to be reinforced matches the shape of the reinforcement to be used;
[0061] Step S2, controlling the mechanical arm to automatically grab the reinforcement for automatic scanning, and ob...

The invention relates to an automatic processing method for an aircraft structure reinforcer. The automatic processing method comprises the following steps: S1, acquiring data of a to-be-reinforced area of an aircraft structure through a handheld laser scanner; s2, a mechanical arm automatically grabs the reinforcer for automatic scanning; s3, a cutting path is set in a reinforcement CAD digital model and is registered with real data to obtain an actual cutting path, and reinforcement cutting is carried out; s4, the mechanical arm guides the cut reinforcer to the scanning area to be automatically scanned again; and S5, virtually assembling the data of the reinforcer and the to-be-reinforced area, calculating the machining allowance, judging whether the precision requirement is met or not, if so, ending the task, otherwise, automatically grinding the reinforcer, and returning to the step S4 after grinding. According to the automatic machining method for the aircraft structure reinforcer, automatic repairing and assembling machining of the aircraft structure reinforcer is achieved, and the problems that manual operation efficiency and precision of repairing and assembling of the reinforcer are low can be effectively solved.
Description
technical field [0001] The invention belongs to the field of aviation manufacturing, and in particular relates to an automatic processing method for aircraft structural reinforcements. Background technique [0002] Whether it is a large passenger aircraft or a fighter jet, the long-term flight operation will inevitably bring about problems such as aging, cracking and deformation of the load-bearing components in the structural area. In the actual maintenance process of the aircraft load-bearing component area, reinforcements are used to strengthen the strength of the area to be strengthened. However, due to the randomness and diversity of the aircraft load-bearing component area to be repaired, there will be various styles of general-purpose reinforcements at the repair site , and on this basis, it is necessary to repair the general reinforcement for the area to be strengthened, so as to realize the precise assembly of the reinforcement and the area to be strengthened to ach...
