Abstract
The invention discloses a detection method capable of qualitatively judging whether an inner cone angle is qualified. The detection method needs a special detection tool, namely a cone angle limit gauge; a cone angle limit gauge cone head is divided into upper and lower cone angle limit cone heads; and both the upper and lower cone angle limit cone heads comprise a handle (1), a rear guide post (2), a limit gauge cone head (3) and a front guide post (4). In order that the cone angle limit gauge is accurately and reliably contacted with a detected conical surface, the structure of the cone angle limit gauge can be combined into a structural form without the guide posts or with the guide posts and the like. The detection method comprises the following steps of: when the inner cone angle of a part is measured, uniformly coating colored mud on the inner conical surface of the detected part, penetrating the cone angle limit gauge into a hole of the detected part from the large head end of the inner cone of the detected part along the axial direction so that the limit gauge cone head (3) is contacted with the detected inner conical surface; rotating the cone angle limit gauge so that the cone angle limit gauge and the detected part produce relative rotation around the same axis; and withdrawing the cone angle limit gauge, observing and measuring the coloring condition of the limit cone head, and judging whether the detected cone angle is qualified according to the distribution of colored parts.
