The company has developed a three-point digital display wheel caliper for railway wheels, including a fixed ruler frame, a movable ruler frame, a measuring head and a ruler body. The ruler body is an arc ruler body, and the movable ruler is hinged at the central axis of the ruler body. The movable ruler frame guides and runs on the outer edge of the ruler body, a fixed ruler frame is fixed on one side of the ruler body, and the free end of the fixed ruler frame and the movable ruler frame are fixed in the same direction. Positioning plate, a central measuring head and a positioning plate are installed at the central axis of the ruler body, a capacity grid is fixed on the outer edge of the arc-shaped ruler body, and a moving grid is installed on the movable ruler frame that is in guiding contact with the capacity grid. . The utility model is a three-point digital display wheel caliper for railway wheels with reasonable design, simple operation, convenient use and strong practicability. The wheel diameter and wheel diameter difference are measured, and the measurement speed is fast and the accuracy is high, which can meet the needs of modern railway construction.
