[0004] However, the vernier caliper indirect measurement method requires a lot of calculations to obtain the final oil hole angle after obtaining the length from the edge of the oil hole to the nearest counterpart surface. The angle value cannot be directly read, and the measurement results are affected by the level of manual operation. Large; seat hole comparison method, for different types of bearing pad oil hole space angles, different special seat holes need to be used for comparison, a large number of special seat hole models need to be made, and the measurement data cannot be directly quantified

The invention relates to a gauge and a method for measuring an angle of a bearing bush oil hole, and relates to the field of engine part gauges. The gauge comprises a measuring mechanism and a metering system, wherein the measuring mechanism comprises a clamping device and a hole positioning device, and the clamping device can rotate around a rotating shaft and is used for coaxially clamping a to-be-measured bearing bush; the hole positioning device comprises a positioning rod, the positioning rod is perpendicular to the rotating shaft, and the positioning rod is used for finding an oil hole of the to-be-measured bearing bush; the metering system comprises an angle measuring device, and the angle measuring device has an initial angle reflecting the position of the clamping device relativeto the positioning rod; and when the to-be-measured bearing bush is clamped by means of the clamping device and the positioning rod is aligned with the oil hole of the to-be-measured bearing bush, theangle measuring device measures a rotation angle of the clamping device relative to the initial angle at the moment. The gauge and the method for measuring the angle of the bearing bush oil hole candirectly measure the angle of the bearing bush oil hole, and are high in precision and efficiency.
Description
technical field [0001] The application relates to the field of inspection tools for engine parts, in particular to a inspection tool and method for measuring the angle of an oil hole of a bearing bush. Background technique [0002] Generally, the non-load-bearing area of the engine bearing is provided with an oil hole for oil supply, and the lubricating oil is introduced into the moving surface formed by the journal and the bearing through the oil hole to reduce the friction coefficient between the journal and the bearing. When there is no oil hole on the bearing pad or the angle of the oil hole is too large, it will cause the bearing pad to fail to add oil; Situation of clinging to death. In order to avoid the above situation, it is necessary to measure the oil hole angle of the bearing pad during design. [0003] In the related art, the traditional oil hole angle detection method mainly includes two kinds, one is the indirect measurement method of vernier caliper, the ...
