Quick Alignment Tool and Method for Large Aeronautical Structural Parts

Abstract

The invention belongs to the technical field of mechanical processing, and specifically relates to a quick alignment tool and method for large-scale aviation structural parts, including a support stud, a correction plate, an adjustment nut and a force application handle; one end of the support stud is provided with a handle for connecting the force application The connection end; the linear chute on the side of the supporting stud, the adjusting nut is screw connected with the supporting stud; one side of the correction plate is slidingly connected with the supporting stud, and the adjusting nut at the top of the correcting plate is flexibly connected. This technical solution is easy to use and has no excessive noise; the correction force is easy to control, which can greatly reduce the number of repeated alignments, simplify the alignment process, and effectively solve the long alignment time of large structural parts and the difficulty of accurate alignment straightness The problem of large size and high labor intensity of workers avoids the quality problems of parts caused by heavy objects hitting parts by mistake.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a quick alignment tool and method for large aeronautical structural parts. Background technique [0002] In the mechanical processing site, in order to eliminate the misalignment of the front and back sides of the parts, ensure the processing quality of the parts, and improve the manufacturing accuracy of large aeronautical structural parts, the straightness of the parts must be aligned when the parts are clamped, and the straightness after alignment If it is zero, the better the processing state of the part is, the better the quality of the processed product will be. At present, due to the high cost of equipment for coordinate rotation and biaxial machining, most factories cannot use this equipment. Based on this, the method of colliding with a large platen is basically used to correct the straightness of parts. This method has the following defect: ...

AI Technical Summary

Problems solved by technology

[0003] 1) Alignment is achieved through impact, and there is a lot of noise;

[0004] 2) The size of the impact force is not easy to control. If the force is too large, the parts move too much, and the parts need to be hit in the opposite direction. If the force is too small, the position of the parts to move is not enough. Generally, multiple collisions are required to meet the alignment requirements, and the alignment process is cumbersome. , not only is it very difficult to accurately align the straightness of the parts, but also the labor intensity of the workers is high and the alignment time is long;

[0005] 3) Hit the parts or tooling with a large pressure plate when correcting the straightness of the parts, there is a risk of bruising the parts by mistake, resulting in quality problems
