涡轮导向叶片蜡模组件是由三个单联叶片蜡件组焊接而成,涡轮导向叶片蜡模组件形状复杂,蜡件收缩率大,且通道公差也大,易变形,检测定位难度很大,需要检测导向叶片蜡模单件和组件安装板两侧面中心位置尺寸,安装板侧面由双斜面形成空间位置,该测量装置既实现各单件通道尺寸测量,又能满足焊接后的尺寸和焊接后各单联叶片的相互位置要求,边焊接边检查。由于蜡件熔铸成型时,每个蜡件尺寸不同,变形大,因此需要此测具克服位置尺寸公差进行测量,从结构上采用斜块涨紧,并限制蜡件叶片的理论极限位置,确保组焊接件位置,采用UG三维建模,建立三个叶片蜡件空间的焊接的位置,采用螺纹压紧机构,在设计时合理选取倒棱厚度和方向,消除其影响;斜块涨紧高度位置取在叶片中心位置,保证三联叶片准确位置,用可调式斜块限制线性移动,并有限位机构进行测量,解决了多联涡轮导向叶片蜡模组件焊接位置的测量。
Turbine guide vane wax module assembly is composed of three single-leaf blade welded together, the turbine guide vane wax mold components complex shape, wax shrinkage, and the channel tolerance is also large, easy to deform, the detection of positioning is very difficult Large, the need to detect the guide vane wax single component and the mounting plate on both sides of the center of the side of the size of the mounting plate side by the double bevel to form a spatial position, the measuring device to achieve both single-channel size measurements, but also to meet the welding size and After soldering the mutual requirements of the single leaf, while welding edge inspection. Due to the different sizes and deformities of each wax, it is necessary to measure the position tolerance to overcome the dimensional tolerances of the components. Tilting up from the structure and limiting the theoretical limit position of the wax leaves ensure that Welding position, the use of UG three-dimensional modeling, the establishment of the three leaves wax space welding position, the use of thread compression mechanism, reasonable choice in the design chamfer thickness and direction, to eliminate its impact; In the center of the blade, the accurate position of the triple blade is ensured, the linear movement is limited by the adjustable inclined block, and the measurement is carried out by a limited position mechanism to solve the measurement of the welding position of the wax mold assembly of the multi-turbine guide vane.
