Six-degree-of-freedom location posture adjusting device for automatic assembly of large parts

Abstract

A six-degree-of-freedom location posture adjusting device for automatic assembly of large parts in the fields of assembling and docking comprises a base, three PPSR branch chains arranged on the base, and an adjusting moving platform connected to a rotary pair at one ends of the PPSR branch chains and having a large part bracket, wherein the large part to be subjected to gesture adjusting is fixedly connected with the large part bracket, a first moving pair is arranged on the base, the second moving pair is correspondingly arranged on the first moving pair, and moving directions of the first moving pair and the second moving pair are horizontally vertical; the first moving pair and the second moving pair are both realized by a guide rail slider and a lead screw nut which are arranged in parallel. According to the present invention, the large part docking assembling process method is combined with the location gesture adjusting movement of a parallel mechanism, the automatic precise assembly of the large parts is realized, and the device has the characteristics of simple control manner, high operation precision, high assembly efficiency, large movement range, and the like.

Description

technical field [0001] The invention relates to a technology in the field of assembly and docking, in particular to a six-degree-of-freedom positioning and posture adjustment equipment for automatic assembly of large parts. Background technique [0002] At present, in the assembly process of large-scale parts in my country, such as the assembly between aircraft cabin sections and the assembly between bazooka bodies, process compensation and tooling are mainly used to ensure the assembly accuracy of large parts. This method is easy to cause bumps and stagnation, easy to generate stress, low efficiency and high labor intensity for workers. To solve this problem, a six-degree-of-freedom positioning and attitude adjustment equipment for automatic assembly of large parts was developed, which can improve the production efficiency of the production line while improving the assembly quality and reduce the labor intensity of workers. Contents of the invention [0003] The present ...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the fact that multiple high-cost and high-precision ball pairs must be equipped to work in the prior art, and a large range of translational motion cannot be realized in a horizontal plane passing through the central axis and perpendicular to the central axis, so the scope of application is limited; and Part of the existing technology has low accuracy and efficiency of visual and manual operation, which seriously affects the production quality and production efficiency. A six-degree-of-freedom positioning and attitude adjustment equipment for automatic assembly of large parts is proposed. High precision, high assembly efficiency, large range of motion, etc., can realize automatic precision assembly of large parts
