    摘要:

    提出數(shù)控車床動(dòng)力卡盤輸入推拉力的直接監(jiān)測(cè)方法,，研制了動(dòng)態(tài)測(cè)量推拉力的回轉(zhuǎn)拉壓力傳感器,，并分析了離心力導(dǎo)致的彎曲變形、膨脹變形和彎曲振動(dòng)對(duì)傳感器測(cè)量誤差的影響,，提出了膨脹變形引起的測(cè)量誤差的補(bǔ)償算法,。試驗(yàn)表明，回轉(zhuǎn)拉壓力傳感器能較好地監(jiān)測(cè)動(dòng)力卡盤的輸入推拉力變化,，該方法比監(jiān)測(cè)回轉(zhuǎn)液壓缸的供油壓力更可靠,，并具有監(jiān)測(cè)裝置不容易受冷卻水和鐵屑污染的優(yōu)點(diǎn)。

    Abstract:

    A direct input push-pull force monitoring method with rotary pull-press force sensors was proposed. It was analyzed how the centrifugal force affecting the error the rotary pull-press force sensors. An algorithm was disclosed to compensate the error from the expansion under the centrifugal force. The rotary pull-press force sensor was used to monitor the input force of the power chuck in the experiment. It monitored the variation of the input push-pull force of the power chuck well. The direct monitoring of the input push-pull force was more reliable than the indirect monitoring of the oil pressure. The input push-pull force sensor was more difficult to be polluted by the cooling water and scrap iron.
