Abstract
The utility model discloses a parallelism measuring device which comprises a base, a telescopic frame and a measuring device. The back face of the base is provided with four positioning parts, and the four positioning parts are quadrilaterally arranged. The front face of the base is provided with the telescopic frame, and the measuring device is arranged on the telescopic frame. The telescopic frame is stretched to an appropriate position, thus the four positioning parts on the back face of the base fall upon the surface of a reference cylinder. Four points slide along the circumferential direction of the reference cylinder when contacting the surface of a cylinder. The measuring device starts to shift from a starting position until the measuring device shifts to another direction, thus the maximum offset can be read. The parallelism measuring device provided by the utility model is moved to the other end, and the above operations are repeated, thus another maximum offset can be acquired. Based on the comparison of the maximum offset acquired from the two measurements, the parallel error of a bus between the surfaces of two cylinders can be easily found out.
