Description of the invention () The invention relates to an X, γ, and z-axis relative judgment detection method and its device addition (―), which is invention 978 Addition of patent No. 4 "X, y, z-axis relative interpretation detection method and device" (1), which is to make the zero-degree reference of the z-axis of the base to achieve the purpose of rapid interpretation, and Another set of positioning pins is added, and a guide groove with a concave groove is formed on the upper periphery of the ball frame in the x-axis, and the set of positioning pins provided on the base is penetrated into the track restricted to the concave groove. The X-axis and γ-axis can be swiveled and rotated in accordance with the orbit, so that they can quickly stand still to provide a flat gene of χγ. By using an appropriate position on the bottom base of the outer shell, a positioning screw can be turned on When not in use *, the ball frame and the inner ball pivot are locked by the positioning screws, which can reduce the wear on the bearing swing when not in use. According to the original mother's observation, the inner ball frame and the middle ball frame are mainly used to position the bearing in a circular frame according to different axial directions. The X-axis and Y-axis can swing with the mid-axis frame, respectively, and provide a 0 ° reference plane for both the X-axis and Y-axis at rest. The ring frame is an M positioning bearing and perpendicularly intersects the middle ball positioning bearing. The direction is pivoted in an outer-ball-like (Z) axis on the base, which relies on the inner ball frame and the mid-ball frame to move synchronously with the X-axis and Y-axis, respectively, and in the outer ball-shell (Z) axis. There is a displacement relationship of relative rotation between them, and the zero-degree reference scale and latitude and longitude scale can be set by the inner, middle and outer spherical tops. The reference plane fixes the base to the outer spherical shell (Z) axis according to the The plane reference shared by both the inner ball frame and the middle ball frame, and those who can judge the plane at various angles, the data can detect a plane or vertical or inclined _______________________ —-......... .......

The data of the invention description (), and at the same time by setting in the inner ball frame North arrow, M can know the direction of a tilt angle. However, the design of the original mother case, when the base 圼 is tilted left and right during use, the middle ball frame and the inner ball frame use the Υ axis as the rotation axis to produce a rotational displacement on the XX axis. Due to the weight of the bottom weight of the inner ball frame, the middle ball frame and the inner ball frame are shaken in the XX axis, which cannot be stopped quickly, so that the zero-degree reference scale of the outer ball shell produces an accurate result on the XX axis. Give in. In view of the fact that the original mother case can be judged more quickly, the inventor hopes to provide a solution. The measurement results will be improved, and the research and design system will be concentrated, and they have engaged in the design, production and sales of related products for many years. Based on the professional technical knowledge and practical experience and the results of research and design, the X-, Y-, and Z-axis relative judging and detecting method and the device addition of the present invention were finally developed (I). M provides more accurate, fast and simple users. . Printed by the staff of the Central Bureau of Standards of the Ministry of Economic Affairs and printed by the company (please read the precautions on the back before filling out this page) The main purpose of the present invention is to add a set of positioning pins on the base and place it in the X axis A guide rail with a concave groove is formed on the upper periphery of the ball frame, and the set of positioning pins provided on the base penetrate into the track restricted to the concave groove. The κ forces the X axis and the Υ axis to swing and rotate along the track as a whole. , And can make it quickly stationary to provide a flat gene. A second object of the present invention is to borrow a positioning screw at an appropriate position on the bottom base of the outer spherical shell, so that when not in use, the M positioning screw shuttles the ball frame and the inner ball frame to the M, which can reduce the Those that cause wear on the bearing when not in use.
