請教各位：
    公司現做一圓盤(pán)，圓盤(pán)由電機通過(guò)變速箱帶動(dòng)而轉動(dòng)，圓盤(pán)每旋轉一周都必須停留在同一位置，由于變速箱間隙較大，我擔心如果用伺服或步進(jìn)電機控制，可能由于機械精度不夠而影響圓盤(pán)在每次旋轉過(guò)程中不能停留在同一位置，請教各位高手如何精確定位圓盤(pán)的位置？

如果要求定位很準確可以考慮機械定位,即圓盤(pán)轉一圈後,用氣缸帶動(dòng)頭部是V字型滑塊插入圓盤(pán)上也要有V字型的槽中,同時(shí)圓盤(pán)轉一圈後伺服也要釋放,以保證V字型滑塊插入V字型的槽中時(shí)圓盤(pán)能自由轉動(dòng).
