Method for measuring the relative orientation of a hollow cylinder and an associated plane cut |
摘要 |
<p>A method and apparatus for measuring the mutual orientation of an optionally oriented hollow cylinder and a cut end of a body containing the hollow cylinder by employing a high-precision laser gyroscope. In using this method, the orientation measurements can be obtained in a more economical and time efficient manner than those employed using conventional methods. The method involves first placing a laser gyroscope on the inside wall of a hollow cylinder and electronically registering the three-dimensional orientation of said laser gyroscope according to at least two angular coordinates relative to a laboratory system; storing the three-dimensional orientation as a first measurement result; placing the laser gyroscope directly on the cut end, or indirectly on the cut end by resting it on a support mechanism that rests on the cut end; electronically registering the three-dimensional orientation of said laser gyroscope according to at least two angular coordinates relative to a laboratory system; storing the three-dimensional orientation as a second measurement result; comparing said first and second measurement results to obtain a value of a phase displacement angle; and displaying the value of the determined phase displacement angle. The device is especially suited for checking the orientation of cylinder heads and cylinder bore axes of large-volume diesel engines.</p> |
