1999 Fixturlaser AB,1,Section 3,水平轴对中调整 激光为基础对中调整仪器 3.1 激光技术 3.2 Fixturlaser 轴对中系统 3.3 实施: 时钟法 3.4 实施: 三点法 3.5 基础和螺栓受约束的状况 3.6 实施: 固定地脚,1999 Fixturlaser AB,2,3.1 激光技术, 激光技术, 概述 什麽是光? 什麽是激光? 激光分级 位置传感器 PSD,1999 Fixturlaser AB,3, 激光技术, Overview,激光器 The laser is a low power semiconductor diode laser with collimating lenses. The laser is modulated in order to avoid interference from other light sources. 接收器（探测器） The detector is a single axis PSD (Position Sensitive Detector). The PSD responds to the laser beam moving over the detector surface. 应用软件 The microprocessor uses the software and the input values from the detector and calculates the result which is displayed on the screen.,1999 Fixturlaser AB,4, 什麽是光 ?,Wavelength between 400 and 700 nm (visible light) Consists of Magnetic field Electric field Energy packets of photons Can be directed,1999 Fixturlaser AB,5, The Laser,Light Amplified by Stimulated Emission of Radiation Originally based on Helium-Neon gas. Made collinear with optics. In semi-conductor lasers the gas mixture is replaced by a crystal.,1999 Fixturlaser AB,6, 激光分级,1999 Fixturlaser AB,7, The PSD,位置敏感探测器 单方向或双方向. 在电极的电流与光和电极的距离成反比 . 线性是主要质量指标.,1999 Fixturlaser AB,8,3.2 Fixturlaser 轴对中测量调整系统, 显示器 安全, 维护 安装 输入尺寸 设定 应用设置 过程-对准激光-测量 评测结果 实施调整,1999 Fixturlaser AB,9,显示器,与 TD 单元的通讯 计算结果 将结果以图形方式显示,1999 Fixturlaser AB,10,安全,Fixturlaser 轴对中系统是二级激光器应防范未成年人: 决不能盯着看激光器. 决不能将激光射入人眼.,1999 Fixturlaser AB,11,保养与维护,除探测器表面外，用湿布沾中性肥皂水清洁. 用用酒精清洁探测器表面. 不要用棉纸，它会擦伤探测器表面.,1999 Fixturlaser AB,12,安装夹具和探测器,将放置 TD 的柱杆装入“V” 型安装支架. 通过“V”型支架底部插入链条.,1999 Fixturlaser AB,13,将 “V” 型支架安装在被测轴上. Use the bracket hook to “catch” the chain. The other end of the chain goes under the shaft and will fit into the bracket cradle to secure the bracket to the shaft.,安装夹具和探测器,1999 Fixturlaser AB,14,安装夹具和探测器,将 TDs （探测器）装入柱杆. The TD-M is mounted to the “movable” shaft. The TD-S is mounted to the “stationary” shaft.,1999 Fixturlaser AB,15,连接电缆,将 TDs用电缆连接起来. 每个TD有两个接头.你使用哪一个没关系 . 用电缆与显示器连接起来. 你使用哪一个没关系。,1999 Fixturlaser AB,16,输入尺寸,从主菜单选程序1.,1999 Fixturlaser AB,17,输入尺寸,测量 “A” 尺寸,1999 Fixturlaser AB,18,输入尺寸,输入 “A” 尺寸 轻触 A,输入尺寸, 并输入 “A” 尺寸轻触 OK 确认数值,1999 Fixturlaser AB,19,输入尺寸,测量并输入“B” & “C” 尺寸.,1999 Fixturlaser AB,20,输
