Technical Field
The invention relates to a device for detecting the position degree of an air vent of an automobile axle housing, in particular to a tool for detecting the position degree of a hydraulic bulging automobile axle housing hole with conical surface and square cross section positioning.
Background
The axle housing is one of important parts on an automobile, not only supports and protects a main speed reducer, a differential mechanism, a half shaft and the like, but also is a storage cavity of gear lubricating oil. After the axle housing main part is processed, a thread vent hole (an exhaust passage for the axle housing sealing cavity) needs to be drilled at the upper part so as to ensure the balance of the internal pressure and the external pressure of the axle housing. The axle housing air vent often receives the impact of gear oil when the car is gone, easy oil impregnate, and air vent department welds the oil baffle disc, if air vent positional deviation is great, can lead to oil baffle disc and main reducer driven gear to interfere.
At the present stage, most axle housings are manufactured by adopting a stamping welding method, and hydraulic bulging axle housings are gradually entering the axle housing market due to high overall strength, rigidity and fatigue life, and the same axle assembly workshop and the same type of axle housing can simultaneously have two forms of stamping welding and liquid bulging. Because of the frock of boring the screw thread air vent is attacked to hydraulic bulging axle housing is completely different with the impulse welding axle housing, generally accomplish in the liquid bulging axle housing manufacturing enterprise and attack behind the axle housing air vent process of boring, transport again and carry out follow-up processing and assembly to ordinary axle housing assembly line. No matter what kind of technology is made the axle housing, all need to use full-automatic gas tightness check out test set to detect the axle housing die cavity leakproofness at last, so the requirement of the screw thread venthole position size uniformity of different technology axle housings is especially important.
At present, a positioner or anchor clamps research for boring tapping axle housing air vent is more, mainly relates to two kinds of products of impulse welding axle housing and internal expanding axle housing, does not have the hydraulic bulging axle housing air vent position degree and detects the frock. Under the condition of no special detection tool, the air vent position degree is measured, the axle housing is required to be hoisted to a working platform, the longitudinal central line and the transverse symmetrical line of the axle housing are aligned, the length measuring tool is used for indirectly measuring and calculating, and the measurement is time-consuming, labor-consuming and low in precision.
