經緯儀主(zhu)要軸線介紹

一、 經緯儀有哪些軸

經緯儀主要有：豎軸(zhou)、橫軸(zhou)、望遠鏡視準(zhun)軸(zhou)、和照準(zhun)水準(zhun)管軸(zhou)。

二、應滿足條件

經(jing)緯(wei)(wei)儀是根據水(shui)(shui)(shui)平(ping)(ping)角(jiao)和豎(shu)直(zhi)(zhi)(zhi)角(jiao)的(de)測(ce)角(jiao)原理(li)制造的(de)，當水(shui)(shui)(shui)準(zhun)管器泡居(ju)中(zhong)時，儀器旋(xuan)轉軸(zhou)豎(shu)直(zhi)(zhi)(zhi)、水(shui)(shui)(shui)平(ping)(ping)度(du)盤水(shui)(shui)(shui)平(ping)(ping)，則(ze)要(yao)(yao)求(qiu)水(shui)(shui)(shui)準(zhun)管軸(zhou)垂(chui)直(zhi)(zhi)(zhi)豎(shu)軸(zhou)。測(ce)水(shui)(shui)(shui)平(ping)(ping)角(jiao)要(yao)(yao)求(qiu)望遠鏡繞橫(heng)(heng)(heng)軸(zhou)旋(xuan)轉為(wei)一個(ge)豎(shu)直(zhi)(zhi)(zhi)面，就必須保(bao)證視準(zhun)軸(zhou)垂(chui)直(zhi)(zhi)(zhi)橫(heng)(heng)(heng)軸(zhou)。另一點保(bao)證豎(shu)軸(zhou)豎(shu)直(zhi)(zhi)(zhi)時，橫(heng)(heng)(heng)軸(zhou)水(shui)(shui)(shui)平(ping)(ping)，則(ze)要(yao)(yao)求(qiu)橫(heng)(heng)(heng)軸(zhou)垂(chui)直(zhi)(zhi)(zhi)豎(shu)軸(zhou)。照準(zhun)目標(biao)使用豎(shu)絲，只有橫(heng)(heng)(heng)軸(zhou)水(shui)(shui)(shui)平(ping)(ping)時豎(shu)絲豎(shu)直(zhi)(zhi)(zhi)，則(ze)要(yao)(yao)求(qiu)十(shi)字絲豎(shu)絲垂(chui)直(zhi)(zhi)(zhi)橫(heng)(heng)(heng)軸(zhou)。為(wei)使測(ce)角(jiao)達到(dao)(dao)一定精度(du)，儀器其它狀態也應達到(dao)(dao)一定標(biao)準(zhun)。綜上所(suo)(suo)述，經(jing)緯(wei)(wei)儀應滿足的(de)基本幾何關系如(ru)圖(tu)所(suo)(suo)示(shi)：

1、照準部水準管軸(zhou)應垂直于(yu)豎軸(zhou)；LL⊥VV

2、十字(zi)絲豎絲應垂直于(yu)橫軸；

3、視準軸應垂(chui)直于橫(heng)軸；CC⊥HH

4、橫軸應垂(chui)直(zhi)于豎軸；HH⊥VV

5、豎(shu)盤指(zhi)標應處于(yu)正確位置；

6、光學對中(zhong)器(qi)視準軸應該與豎軸中(zhong)心線重合。
