Ensuring the quality of assembly of fuel equipment junctions in the conditions of batch production by kitting-up with ranking of part dimensions

Abstract

In connection with the decline in the serial production of Ukraine, the use of selective
kitting-up methods in the assembly of products of fuel equipment is not technological. The author
suggests a method of kitting-up with a ranking, which provides the required precision with full
batch assemblability of parts. The principles of the new kitting-up method have been tested using
the example of fuel equipment manufactured by the Kharkov Tractor Plant. The study involved
three parts, forming two junctions: body, valve and bushing. Studies were conducted in shop
conditions. A comparison was made between the precision of kitting-up and work in progress with
selective assembly and assembly with ranking. The use of assembly with ranking allows for batches
of 5-15 parts to achieve the required picking precision with easily meet the requirements for
precision manufacturing. The proposed method of organization of production is recommended for
introduction in enterprises engaged in the production of fuel equipment.
