Key Technology Research On The High Accuracy Numerical Control Linkage Rotary Table

Along with science's and technology's development and the social progress, the numerical-control machine is developing toward high speed, high accuracy and multi-axis motion integration direction. Internationally, multi-axis motion integration technology is the symbol of a country production equipment automation level. And the high accuracy numerical control linkage rotary table is one of multiple spindle linkage numerical-control machine tool key components. Therefore research of the high accuracy multiple spindle numerical control work table is key point of various countries' research competition.The present paper takes"Key technology research of the high accuracy numerical control linkage rotary table"as the topic. One economical suitable high accuracy numerical control linkage rotary table has designed through the research; Has constructed the high accuracy numerical control rotary table mathematics modelling after the fundamental research; And has conducted the research to the numerical control linkage rotary table control tactics; Finally the system key's gear rack is carried on the optimization design by using the finite element. This topic's research has carried on the rich significance exploration for the high accuracy numerical control linkage rotary table technology advancement. this topic main innovation spot:⑴Through the research of the domestic and foreign correlation techniques, 5 kinds of high accuracy numerical control linkage rotary table have been designed, then through the comparative analysis research, one economical suitable high accuracy numerical control linkage rotary table plan has been established——servo hydraulic pressure driving gear rack vice-rotary table again.⑵Through the research, one kind of new digital actuation controlled valve has been designed. And it provides the condition for the high accuracy numerical control linkage rotary table .⑶Combine the fuzzy theory and the PID control method organic. Discussing control tactics of the high accuracy numerical control linkage rotary table, which has laid a good foundation for the following implementation circuit design.
