The invention relates to the technical field of ship construction, and particularly discloses a base backrest positioning and marking device and a positioning and marking method. The device comprises a positioning scribing assembly and a height measuring assembly. The positioning scribing assembly comprises a fixing plate and a clamping plate, the fixing plate is rotationally connected with the clamping plate through a pin shaft, the axis of the pin shaft is parallel to the ground, a spirit bubble is fixedly installed on the fixing plate and used for adjusting the levelness of the fixing plate, a rotating shaft is rotationally connected to the fixing plate, and the axis of the rotating shaft is vertical to the fixing plate. A light-emitting unit is detachably connected to the rotating shaft, and light emitted by the light-emitting unit is parallel to the fixing plate; the height measuring assembly comprises a telescopic scale rod, the telescopic scale rod is arranged to be vertical to the ground and can stretch out and draw back in the direction vertical to the ground, the clamping plate detachably clamps the outer side wall of the telescopic scale rod, scale values are arranged on the telescopic scale rod, and the scale values are used for identifying the position of the light-emitting unit relative to the ground. The device solves the problem of low positioning and scribing precision.

    本发明涉及船舶建造技术领域,具体公开了基座靠背定位划线装置及定位划线方法。该装置包括定位划线组件和高度测量组件;定位划线组件包括固定板和夹持板,固定板通过销轴与夹持板转动连接,销轴的轴线平行于地面,固定板上固定安装有水平泡,水平泡用于调整固定板的水平度,固定板上转动连接有转动轴,转动轴的轴线竖直于固定板,转动轴上可拆卸连接有发光单元,发光单元发出的光线平行于固定板;高度测量组件包括伸缩刻度杆,伸缩刻度杆竖直于地面设置,且能沿竖直于地面的方向伸缩,夹持板可拆卸夹持伸缩刻度杆的外侧壁,伸缩刻度杆上设置有刻度值,刻度值用于标识发光单元相对于地面的位置。该装置解决了定位划线精度低下的问题。
