Flexible assembly digital fixture device

Abstract

The invention relates to a digital flexible assembly frame device, which consists of a frame framework and 16 mobile shape adjusting units, wherein the frame framework is formed by assembling an upper beam component, a lower beam component and an upright post component; a guide rail, a slider and a rack are arranged on the frame framework; the number of the mobile shape adjusting units is 16, wherein 8 mobile shape adjusting units are arranged on the upper beam component, and 8 mobile shape adjusting units are arranged on the lower beam component; the mobile shape adjusting units on the lowerbeam component and the mobile shape adjusting units on the upper beam component are symmetrically arranged; and each mobile shape adjusting unit is connected with a pair of sliders in a mode of screwed joint and comprises a mobile bracket, a motor, a speed reducer, a coupler, a lead screw, an angular contact bearing, a copper sleeve, a guide rod sleeve and other parts. The mobile shape adjusting units are core components of the digital flexible assembly frame device, and free shape adjustment in two directions of assembly points is realized by the mobile shape adjusting units. The digital flexible assembly frame device has the advantages of quick shape adjustment, high precision, good openness, strong universality and simple and reliable structure, and realizes assembly of various wall board parts with one frame in aircraft assembly.

Description

A flexible assembly digital jig device technical field The invention relates to a flexible assembly digital jig device, which is used for the assembly of aircraft panel parts and belongs to the field of aircraft manufacturing and assembly. Background technique Aircraft assembly is a complicated process with relatively high technical requirements. Thousands of parts must be accurately positioned, connected, and assembled, and the workload is very heavy. The traditional aircraft assembly adopts a one-to-one model frame card board chess style. Each model frame corresponds to a set of card boards, and the positions of the ends of the card boards connected to the model frame are fixed. A set of frame frames can only be used for An assembly object, which requires the manufacture of a large number of assembly frames in the process of aircraft production preparation, makes the research and development cycle of the aircraft longer, the cost becomes higher, and occupies a very large ...
