Abstract


Engine camshaft is the major driving part for engine admission gear and one of the five core parts for diesel engine. The cam profile controls the movement of the valves to change the air in the cylinder. The clearance of valve and distribution efficiency depend on the size and precision of the cam. So it is very necessary to measure cam’s form and location error efficiently and precisely. With the high development of locomotive industry and advancement of manufacturing process, automatic line has been applied during camshaft production, because the traditional optic mechanical gauge and templet measurement are not efficient and need to be dealt with by manual date, which can’t meet production demand. Therefore, the thesis does further research on the key technology for on-line measure system of camshaft’s form and location error.1.The thesis introduces the backgrounds and meanings of this research, shaft parts measurement technology and error compensation technology at home and abroad. Then it analyses difficulties and key technology of on-line measurement. Based on it, the thesis suggests to use measurement theory and error theory to study measure principle of form and location error of camshaft.2.Set up on-line measure system of GEVO 16 engine camshaft locating on turn-milling center. It includes probe system, distribution mode of collecting points, date collection and development of transmit program.3.Analyse the errors source of measure system and error compensation method. Compared with CMM measure data in lab, verify the precision of measure system and optimize the processing technic of camshaft.
