Assembly butting part end face automatic finishing process method

Abstract

The invention belongs to component butting assembly technology, and relates to a butting part end face automatic finishing process method. The invention combines laser scanning equipment with a numerical control machine tool according to the production requirements for the coordinated assembly of assembly bonding surfaces in an aircraft component production and assembly site, obtains three-dimensional graphics by scanning the processing surfaces, and automatically calculates the processing volume by applying a software algorithm to generate a processing program, so as to complete the automaticprocessing of the bonding surfaces.

Description

technical field [0001] The invention belongs to component butt joint assembly technology, and relates to a process method for automatic finishing of end faces of joint parts. Background technique [0002] During the assembly process of a certain type of machine, part A and part B are installed and assembled. A total of 4 faces of the two parts need to be bonded to the 4 faces of part B at the same time and connected with bolts. There is a machining allowance on the butt joint surface of part A and part B, and there are several initial butt joint small holes on the butt joint face of part A. When assembling, the milling and cutting process of the butt joint surface must be completed first to ensure that the two parts fit together. Next, the butt hole should be processed to ensure the accuracy and coaxiality of the butt joint hole of the two parts. Finally, bolts and nuts should be installed to assemble the two parts. [0003] The current process method is to smear red lead p...

Problems solved by technology

The processing surface is manually scraped, and the processing quality mainly depends on the skills and experience of the operator. The manual scraping method is not only time-consuming and laborious, but also because the processing data cannot be read intuitively, it is easy to produce poor quality. When grinding steel parts and products with high hardness, it will An unsafe accident occurred in which the grinding sheet was broken and injured by flying

Butt hole diameter accuracy H7 uses manual reaming, because the product material is hard, manual reaming is difficult, and the processing is time-consuming and laborious

[0004] Traditional method: Manual scraping is used on the assembly and docking surface, and the processing quality mainly depends on the skills and experience of the operator. The manual scraping method is not only time-consuming and laborious, but also because the processing data cannot be read intuitively, it is easy to produce poor quality. When the product is high, there will be an unsafe accident that the grinding sheet will break and fly and hurt people

The precision of the butt hole diameter is high, and manual reaming is used. Due to the hard material of the product, manual reaming is difficult, and the processing is time-consuming and laborious.
