Cotton-picking Head Of Quality Control And MRO System Building Research

Xinjiang is the main producing areas of China commodity cotton production accounts for almost half of the country, cotton as a pillar industry in Xinjiang, Xinjiang to maintain economic growth and maintaining social stability is of great significance, with the increase of the cost of artificial cotton picker, cotton harvest close mechanization become an inevitable trend, Xinjiang’s cotton picker mainly for Case, John Deere and domestic 4MZ-5 type horizontal spindle cotton picker pick three kinds of cotton picker as a complex harvesting equipment, its operation requirements high stability and reliability, as the core component of the first cotton picker cotton picker, now some of the key components of domestic cotton picker head is still dependent on imports, the paper mainly for quality control point picker head assembly and maintenance processes to improve cotton picker head of quality main contents are as follows:(1) by the horizontal type ingot pick cotton picker cotton picker head assembly mechanism features and processes are analyzed, and combined with the actual work processes during the first cotton picker, cotton picker head assembly to analyze the quality control process connotation.(2) through the study process on cotton picker head assembly process, the relations with its quality cotton picker head assembly error, building transfer model based on the key components of error cotton picker head contact surface, analyze the assembly process of parts with the relationship established the contact section JSS matrix, according to the initial conditions of the assembly of parts and assembly precision, the error path to search for all the assembly process may have to find precision brother error component distribution in each transmission path.Verified and analyzed by the cotton picker head bevel gear and drive shaft assembly.(3) statistical analysis of the cotton picker head assembly and repair and maintenance process of the key information for the combined business needs MRO support systems and building blocks to build support platform is based on systematic cotton picker head MRO, statistical records during assembly and maintenance various information on the assembly and maintenance personnel to provide efficient assembly and maintenance of channels.
