Z3050型搖臂鉆床PLC改造,z3050,搖臂,鉆床,plc,改造 摘 要 搖臂鉆床是用于一些大中型企業(yè)對工件的加工，老式的搖臂鉆床電氣控制線路是以各種不同的繼電器為主要元件，所以負擔比較沉重，大量的接觸器需要大量的資金，在生產加工工件時接觸器觸頭不斷的關斷會造成觸頭的發(fā)黑。 在安裝這些繼電器時需要大量的空間。維修依靠經驗，繼電器的位置發(fā)生變化或者是線路發(fā)生改變維修更是困難。 隨著現代社會生產的發(fā)展和技術的進步，現代化工業(yè)生產自動化水平的日益提高及微電子技術的飛速發(fā)展，出現了一種可編程控制器（PLC）。所以我想能不能用可編程控制器（PLC）結合一些外部設備代替搖臂鉆床電氣設備的控制，以降低床子的造價費用，并且還提高床子的加工精度、延長使用壽命。 關鍵詞：Z3050型搖臂鉆床、PLC、自動控制。 Summary Shaking the arm drills a bed to be mainly more applied than some big and medium-sized business enterprises to used for processing work piece, shaking arm to drill the bed electricity control circuit because of the old style, with various different after electric appliances for main component, so burden more heavy, a great deal of of contact the machine even need a great deal of funds, getting in touch with a machine to touch when the production process a work piece one's continuous contact will result in a nigrescent circumstance of touching the head. Even need a great deal of space while installing these after the electric appliances.What to depend on more is experience in the aspects of maintaining, once after the position occurrence of the electric appliances change perhaps is a circuit occurrence to change that to maintain is also difficulty. Modernize industry production to automate along with development and technical progress of modern and social production level of raise increasingly and the micro-electronics fly technically to develop soon, appearing a kind of programmable controller(PLC).So I conceive the control that can combine some exterior equipmentses to replace to shake arm to drill bed electricity an equipments with the programmable controller(PLC), the since low bed son builds price expenses, and still raises bed son to process accuracy and the extension service life etc..
