Description

Rotating object angle measuring device

The present invention relates to an angle measuring device, and more particularly to an angle measuring device for rotating an object.

Previously, the angle was measured by aligning the outer diameter of the column of the object to be tested with the sheet-like aperture or the center of the object to be measured with respect to the center of the object to be tested as the reference starting point, and there was no vertical direction guiding device. This new design uses a guiding alignment device to restrain the vertical center position such as the circle (square/square/concave/cone/laser) and the rudder, so that the rudder protractor does not cause misalignment and misalignment. The design is to actively guide the vertical direction to align with the center to be tested.

Previously, the protractor was used to fix the center of the circle on a horizontal plane. The disadvantage is that it needs to be locked into the object to be tested. This new design can also use the laser guiding and aligning device to align the vertical center position. It is necessary to drill or damage the object to be tested.

In view of the above problems, the rotating object angle measuring device of the present invention newly uses a guiding and aligning device to restrain the boundary (such as a circle/square/cone) from aligning with the center position of the rudder, so that the rudder protractor is not caused by the misalignment. Offset problem.

The rotating object angle measuring device of the invention is a measuring shaft, an airfoil surface and the like The angle device is mainly constructed as a metal crucible, which uses a metal crucible to guide the aperture into the column of the object to be tested, and the center of the metal crucible is aligned with the reference. The device provides the function of vertical/horizontal cylinder and drawing rotation angle measurement. .

The invention is provided with a guiding device between the metal crucibles, thereby embedding the inner diameter or the outer diameter of the object to be tested, thereby preventing the fixed aperture from moving or loosening in any direction, so that the measurement is more accurate, and the bottom surface of the metal crucible is provided. A plurality of metal 钣 attachments (thimbles, convex shafts, concave shafts, and lasers) are used to adjust the metal rafting method to increase the effectiveness of measuring the rotation angle of the cylinder or the origin.

This Summary and the following detailed description and the accompanying drawings are intended to further illustrate the manner, the Other objects and advantages of the present invention will be described in the following description and drawings.
