Abstract
Description
Technical Field
[0001] The invention discloses a device and method for aligning slotted nut locking plate holes of an aviation accessory casing, belonging to the technical field of aviation accessory casing installation. Background Art
[0002] The accessory casing of an aircraft engine contains multiple gear shaft assemblies, which are secured at both ends using slotted nuts. Locking plates are often used to secure the slotted nuts. The locking plates are placed in corresponding slots in the slotted nuts and nut mounting bases, with the nut slot width allowing for no more than 0.25mm of clearance on either side.
[0003] Currently, tightening and assembling slotted nuts equipped with locking plates is still primarily a manual process. During the tightening process, the alignment of the nut slots with the mounting base slots is visually observed. Workers must operate the tightening tool to slowly tighten the slotted nut in the same direction, constantly observing the nut slot position. Tightening must stop when a slot aligns with a slot in the mounting base. This process generally requires the worker's experience to ensure and complete.
[0004] Some methods use visual cameras to monitor the slot position for alignment, but due to the accuracy limitations of visual cameras, as well as the influence of the environment, lighting, and product spatial position, they often fail to meet application requirements and are not universal. In existing technical methods, the slotted nut and mounting base slot position alignment relies on manual visual inspection and manual alignment, which has significant disadvantages.
[0005] It did not reduce the labor intensity of the workers;
[0006] The instability of manual operation may result in improper alignment during one tightening, and the nut cannot be reversed, so it may be necessary to loosen and retighten it, which is time-consuming and labor-intensive.
