Abstract

The invention provides an auxiliary tool for rib precision hole manufacturing. The auxiliary tool comprises a base, cushion blocks, a first drill plate, a second drill plate, a lining, quick changing drill sleeves and a process boss, wherein the cushion blocks are fixed on the left side and the right side of the base; the process boss is mounted on the reference surface of the base and flatly attached with the reference surface of the base; the first drill plate is mounted on the cushion blocks, the quick changing drill sleeves are mounted on the first drill plate, the second drill plate is fixed on the base, and the lining is mounted on the second drill plate. The auxiliary tool for rib precision hole manufacturing realizes quick positioning of a workpiece and double guidance of an internally installed rib precision hole manufacturing process and guarantees the location degree, perpendicularity and precise dimensions of a precision hole.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing design, and in particular relates to an auxiliary tooling for the manufacture of rib precision holes. Background technique [0002] The manufacturing of precision holes in aircraft structural parts has high requirements. It must not only ensure high precision requirements, but also meet the requirements of position and verticality. Especially, the rapid and accurate manufacturing of precision holes for built-in ribs has always been a manufacturing problem. Traditionally, a drilling template is used for precision hole manufacturing. Since this method has only one guide hole, it is difficult to guarantee the position and verticality of long-distance precision hole manufacturing, and the efficiency is low, and the product failure rate is high. Contents of the invention [0003] What the present invention aims to solve is the technical problem of low manufacturing efficiency and poor p...
