性能特點(diǎn) Performance characteristics
1、可實(shí)現(xiàn)0-360°范圍內(nèi)任意角度的測(cè)量,測(cè)角精度高
2、多齒分度臺(tái)是利用多齒嚙合的平均效應(yīng)原理,具有極高的分度精度。
3、720齒和391齒進(jìn)行差動(dòng),等效281520齒多齒分度臺(tái),能提供最小到4.6″的角度間隔。
4、差動(dòng)多齒分度臺(tái)的自動(dòng)分度是通過步進(jìn)電機(jī)的傳動(dòng)實(shí)現(xiàn)的,控制定位精度高。
5、上位機(jī)(如計(jì)算機(jī))可通過串口發(fā)送控制齒盤運(yùn)動(dòng)指令,并讀取自準(zhǔn)直光管的測(cè)量值。
6、公開的通訊協(xié)議,儀器提供兩個(gè)測(cè)量軟件:一般測(cè)量和棱體測(cè)量。用戶也可根據(jù)自己的測(cè)量要求,按照通訊協(xié)議,編制相應(yīng)的測(cè)量軟件。
7、支持手動(dòng)測(cè)量、自動(dòng)測(cè)量?jī)煞N模式,測(cè)量速度快,減少人為操作誤差。
8、支持測(cè)量數(shù)據(jù)保存、查看及打印
工作原理 Working principle
1、底座
升降工作臺(tái)和差動(dòng)多齒分度臺(tái)固定在底座上,底座上的三個(gè)底腳螺釘可調(diào)節(jié)底座的水平角度。
2、自準(zhǔn)直光管
自準(zhǔn)直儀是基于自準(zhǔn)直原理,通過光電瞄準(zhǔn)對(duì)被測(cè)件的角位移進(jìn)行精密測(cè)量,自準(zhǔn)直光管中有敏感該位移量的光電傳感器,它將光信號(hào)轉(zhuǎn)換成電信號(hào),再由電箱中的信號(hào)處理電路將其轉(zhuǎn)換成相應(yīng)的角度值。
3、升降工作臺(tái)
升降工作臺(tái)可以對(duì)自準(zhǔn)直光管的上下位置、左右角度、俯仰角度進(jìn)行調(diào)整。
4、差動(dòng)多齒分度臺(tái)
差動(dòng)多齒分度臺(tái)由720齒和391齒齒盤組成,可提供4.6″的分度間隔,自準(zhǔn)直光管的測(cè)量范圍為±19.99″,因此用差動(dòng)多齒分度臺(tái)的轉(zhuǎn)角與自準(zhǔn)直光管的測(cè)量值結(jié)合,就可實(shí)現(xiàn)0-360°范圍內(nèi)任意角度的測(cè)量。
上下兩個(gè)多齒分度臺(tái)是在安裝好后分別檢測(cè)的,每一臺(tái)儀器在供貨時(shí)均附有兩個(gè)多齒分度臺(tái)的檢測(cè)數(shù)據(jù),它標(biāo)明了多齒分度臺(tái)的個(gè)體精度。
5、調(diào)平工作臺(tái)
調(diào)節(jié)調(diào)平工作臺(tái)上的調(diào)整螺釘可調(diào)節(jié)被測(cè)件的水平安裝角度。
6、720齒分度臺(tái)升降旋鈕
差動(dòng)多齒分度臺(tái)整體被殼體罩住,720分度臺(tái)的升降旋鈕伸出,可以手動(dòng)操作,以便于使用者進(jìn)行檢測(cè)前的調(diào)整。
7、電箱
電箱中包括實(shí)現(xiàn)差動(dòng)多齒分度臺(tái)自動(dòng)分度的控制電路和自準(zhǔn)直光管的信號(hào)處理電路。差動(dòng)多齒分度臺(tái)的角度值和自準(zhǔn)直光管的測(cè)量值顯示在電箱的面板上。
8、計(jì)算機(jī)測(cè)量軟件
儀器提供兩個(gè)測(cè)量軟件:一般測(cè)量和棱體測(cè)量。用戶也可根據(jù)自己的測(cè)量要求,按照通訊協(xié)議,編制相應(yīng)的測(cè)量軟件。
