Embodiment Construction

[0023] To request a 100% inspection such as Figure 5 The example shown in which the half angle of the inner cone of the housing nut is 45° ± 30' is used to illustrate the practice of the invention.

[0024] detect as Figure 8 When the shown half angle is the inner cone angle of 45°±30′, the cone angle limit gauges (upper limit, lower limit cone angle limit gauges) are designed and manufactured as follows Figure 9a , 9b The structure shown: the front guide column (4) and the handle (1) of the cone angle limit gauge are designed as an integral structure, the front part is the part of the front guide post (4), the middle part is a cylinder with a boss, and the rear part is It is a cylinder with anti-slip measures (such as knurling). The leading column (4) on the upper limit and lower limit cone angle limit gauges is one and the measured part ( Figure 8 As shown) d hole forms a small clearance fit cylinder, its diameter is taken as d, deviation is taken as g, and the accur...

Abstract

A detection method that can qualitatively judge whether the inner cone angle is qualified or not. This detection method requires a special inspection tool, that is, the cone angle limit gauge. The upper and lower cone angle limit cones all include a handle (1), a rear guide column (2), a limit gauge cone (3) and a front guide column (4), in order to make the cone angle limit gauge and the measured cone surface Correct and reliable contact, the structure of the cone angle limit gauge can be combined into structures such as without guide pillars and with guide pillars. Angle limit gauge, from the big end of the inner cone of the measured part to penetrate into the hole of the measured part in the axial direction, so that the limit gauge cone head (3) is in contact with the tested inner cone surface, and the cone angle limit gauge is rotated so that it is in line with The measured part produces relative rotation around the same axis, exits the cone angle limit gauge, observes the coloring of the measuring limit cone head, and judges whether the measured cone angle is qualified according to the distribution of the colored parts.

Description

technical field [0001] The invention relates to a detection tool for the inner cone angle, in particular to a detection tool for detecting the cone angle when the inner cone is located in the middle of the part. Background technique [0002] At present, the detection methods for the inner cone angle include the coloring detection method, the perfusion mold blank method, the sine gauge measurement method, and the three-coordinate measuring instrument measurement method. ① Coloring detection method; when the cone is in the middle of the part, it is difficult to observe the effect of coloring. Moreover, the coloring effect is generally judged by visual inspection, and it is not easy to quantitatively or qualitatively judge whether the cone angle is qualified, especially when the length of the measured cone is short, because the thickness of the color mud applied to the coloring gauge is not easy to control, it is easy to produce large measurement errors. ② Infusion mold blank...
