Abstract

The invention discloses a crankshaft machining process which is characterized by including the steps of machining blanks by an end face milling and centering special machine, feeding and detecting the blanks on line, then successively machining the blanks by a thrust journal cylindrical turning special machine or numerical control lathe, a thrust journal cylindrical grinding machine, a main journal rough-machining special machine or numerical control lathe, a two-end journal rough machining special machine or numerical control lathe, a connecting rod journal rough-machining universal device with eccentric fixture, special machine, an external milling or internal milling machine, an oil hole machining universal device or special machine, a intermediate cleaning machine, a heat treatment special machine or special tooling, a straightening special machine, a thrust surface grinding special machine, a journal grinding special machine, a special machine or machining center for machining threaded holes and positioning pin holes at two ends, a key milling universal device or special machine, a dynamic balancing special machine, a flaw detection special machine, a polishing special machine, a cleaner, and finally discharging and inspecting products. The crankshaft machining process is simple. As multiple repeated procedures are omitted, work efficiency is improved.

Description

technical field [0001] The invention relates to a crankshaft processing technology. Background technique [0002] The crankshaft is an important part of the engine. Because the crankshaft has the characteristics of complex structure, poor rigidity and high technical requirements, the processing technology is difficult, and its processing quality directly affects the technical performance of the engine. [0003] performance and life, and the crankshaft is a slender rod part, which is easily deformed during processing, which requires [0004] When designing the processing technology, according to the crankshaft material, technical requirements, production capacity and other requirements, comprehensive and comprehensive [0005] Consider processing options. [0006] At present, the crankshaft production process is complicated and there is no unified standard, resulting in uneven quality of the produced crankshafts. Many repeated processes also make the production efficiency l...
