【摘要】：液壓鎖緊軸套是五軸聯(lián)動機(jī)床的關(guān)鍵部件,能夠在壓力載荷作用下發(fā)生較大的彈性變形,鎖緊進(jìn)給軸的轉(zhuǎn)動自由度,對機(jī)床定位鎖緊和加工精度有重要的影響,鎖緊扭矩是液壓鎖緊軸套設(shè)計的重要參數(shù)。為研究軸套內(nèi)工作表面在加工過程中產(chǎn)生的夾緊誤差對液壓鎖緊軸套鎖緊進(jìn)給軸時產(chǎn)生的鎖緊扭矩的影響,首先用有限元方法分別計算了液壓鎖緊軸套考慮夾緊誤差和不考慮夾緊誤差工作時產(chǎn)生的鎖緊扭矩;然后在自主設(shè)計的實(shí)驗(yàn)臺上進(jìn)行鎖緊扭矩測試實(shí)驗(yàn);最后用實(shí)驗(yàn)數(shù)據(jù)對有限元方法計算數(shù)據(jù)進(jìn)行驗(yàn)證。驗(yàn)證結(jié)果說明,有限元方法計算得到的理論數(shù)據(jù)相對實(shí)驗(yàn)數(shù)據(jù)曲線走勢一致,由夾緊誤差引起軸套內(nèi)工作表面的不同形狀直接影響鎖緊扭矩。
[Abstract]:The hydraulic locking shaft sleeve is the key component of the five-axis linkage machine tool. It can produce large elastic deformation under the pressure load, and the rotational degree of freedom of the locking feed shaft has an important influence on the positioning locking and machining accuracy of the machine tool. Locking torque is an important parameter in the design of hydraulic lock sleeve. In order to study the influence of clamping error caused by the working surface of the inner working surface of the shaft sleeve on the locking torque of the hydraulic lock shaft sleeve when the feed shaft is locked, the clamping error caused by the clamping error of the inner working surface of the shaft sleeve is studied. Firstly, the locking torque produced by hydraulic locking shaft sleeve considering clamping error and not considering clamping error is calculated by using finite element method, and then the locking torque test experiment is carried out on the self-designed test bench. Finally, the finite element method is used to verify the calculation data. The results show that the theoretical data obtained by the finite element method are consistent with the experimental data, and the different shapes of the working surface of the sleeve caused by the clamping error directly affect the locking torque.
