Abstract

The invention provides an easily-applied ball surface point positioning method. The method includes the steps of firstly, determining a positioning point on a curved surface part; secondly, enabling the ball surface of a ball point locator to be tangent to the curved surface of the curved surface part to ensure that a tangent point P is the positioning point, wherein a ball handle of the ball point locator is located at the position A1 at the moment, and the axis of the ball handle of the ball point locator, the ball center of the ball surface and the tangent point P are collinear; thirdly, rotating the ball point locator under the conditions that the tangent point P on the curved surface part is unchanged in position and the ball surface of the ball point locator and the curved surface of the curved surface part still keep tangent so that the axis of the ball handle of the ball point locator can be rotated to the required direction, wherein the ball handle of the ball point locator can be located at the position A2 at the moment; fourthly, completing the positioning work. After the positioning method is adopted, the axis of the ball handle of the ball point locator can be rotated to the horizontal reference direction or the vertical reference direction as required, the positioning effect can not be affected, and difficulty of subsequent machining can be lowered.

Description

technical field

[0001] The invention relates to a method for simplifying the use of spherical point positioning, which belongs to the technical field of mechanical processing. Background technique

[0002] When using the ball point locator to locate the positioning point of curved surface parts, the traditional method is to determine the positioning point and the axis direction of the mounting hole of the ball point locator in the normal direction of the profile, such as figure 1 and figure 2 As shown, the ball handle of the ball point locator is at position A1, and its characteristic is that the axis of the ball handle is in the same direction as the positioning point of the profile, the method is intuitive and clear, and it is not easy to make mistakes. However, in the actual processing process, due to the particularity of the selection of the positioning points of curved surface parts, the uncertainty of the normal direction of the positioning points is determined, and ...
