摘 要
隨著信息化產業的高速發展,數控機床的功能日趨完善,數控機床已經完全取代了普通機床,而數控技術是機械加工自動化的基礎,是數控機床的刻心技術,其水平高低關系到國家戰略地位和體現國家綜合實力的水平。今后數控技術又將向著高進化,高速化,高效化,系統化,自動化,智能化,集體化方向發展,并注重工藝適用性和經濟性。
由于z-3040型搖臂鉆床的電氣控制系統存在線路復雜、故障率高、維護工作量大、可靠性低、靈活性差等缺點,本文提出了用PLC對z-3040型搖臂鉆床的繼電器接觸式模擬控制系統進行技術改造,從而保證了電控系統的快速性、準確性、合理性,更好地滿足了實際生產的需要,提高了經濟效益。
本文在分析z-3040型搖臂鉆床的技術特性及工作循環流程的基礎上,給出應用ES系列可編程序控制器對其進行技術改造的系統設計方案。對系統的硬件組成和軟件設計作了闡述。
Abstract
The electrical control system of z-3040 Radial arm drill has many defects such as complex circuit, high failure rate, large maintenance workload, poor reliability and flexibility. This paper introduces the z-3040 Radial arm drill relay contact analog control system reformation with PLC to guarantee the rapidity, accuracy and rationality of electric control system. It satisfied real production demand and enhance the economic benefit.
The original was introduced initial controller of programmable distinguishing feature and performance. Analyses on z-3040’s Radial arm drill technique property and the work cycle distance travelled by a stream of water base, expounded the initial controller of application ES’s set programmable carrying on the technological transformation system design to such, and finish come out the control procedure trapezium picture.
