推板只能在軌道內(nèi)往返運(yùn)動(dòng),用什么機(jī)械結(jié)構(gòu)來(lái)實(shí)現(xiàn)? |

點(diǎn)評(píng)
要求精度的話(huà),這需要伺服
小墨兄正解
驅(qū)動(dòng)銷(xiāo)固定在皮帶上,皮帶帶動(dòng)驅(qū)動(dòng)銷(xiāo)運(yùn)動(dòng),驅(qū)動(dòng)銷(xiāo)卡在滑動(dòng)長(zhǎng)孔里,所以推動(dòng)工作平臺(tái)運(yùn)動(dòng);瑒(dòng)長(zhǎng)孔之所以是腰孔,是驅(qū)動(dòng)銷(xiāo)過(guò)從動(dòng)輪/驅(qū)動(dòng)輪有橫向位移分量。
沒(méi)看出怎么能往返運(yùn)動(dòng)呢
