描述
為什么設置這樣的聯(lián)鎖?為了安全起見,進給變速沖動時不能有進給移動。
聯(lián)鎖的實現(xiàn)方法:SQ1或SQ2、SQ3或SQ4的四個常閉觸點SQ1-2、SQ2-2、SQ3-2和SQ4-2串聯(lián)在KM2線圈回路。當進給變速沖動時,短時間壓下微動開關SQ5,其常閉觸點SQ5-2(9-11)斷開,其常開觸點SQ5-1(11-14)閉合,如果有一個進給操縱手柄不在零位,則因微動開關常閉觸點的斷開而接觸器KM2不能吸合,進給電動機M3也就不能轉動,防止了進給變速沖動時工作臺的移動。
d.圓工作臺的轉動與工作臺的進給運動不能同時進行
聯(lián)鎖的實現(xiàn)方法:SQ1或SQ2、SQ3或SQ4的四個常閉觸點SQ1-2、SQ2-2、SQ3-2或SQ4-2是串聯(lián)在KM2線圈的回路中,
當圓工作臺的轉換開關SA3轉到“接通”位置時,兩個進給手柄可能壓下微動開關SQ1或SQ2、SQ3或SQ4的四個常閉觸點SQ1-2、SQ2-2、SQ3-2或SQ4-2。如果有一個進給操縱手柄不在零位,則因開關常閉觸點的斷開而接觸器KM2不能吸合,進給電動機M3不能轉動,圓工作臺也就不能轉動。只有兩個操縱手柄恢復到零位,進給電動機M3方可旋轉,圓工作臺方可轉動。
