Problems solved by technology
[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 application relates to a checker and method for measuring the angle of the oil hole of the bearing bush, and relates to the field of engine parts checker, including a measuring mechanism and a metering system. The measuring mechanism includes a clamping device and a hole fixing device, and the clamping device can rotate around The shaft rotates, which is used to coaxially clamp the bearing pad to be tested; the hole fixing device includes a positioning rod, the positioning rod is perpendicular to the rotating shaft, and the positioning rod is used to align the oil hole of the bearing pad to be tested; the metering system An angle measurement device is included, and the angle measurement device has an initial angle reflecting the position of the clamping device relative to the positioning rod; when the bearing bush to be measured is clamped by the clamping device and the positioning rod is aligned When the oil hole of the bearing bush is to be measured, the angle measuring device measures the angle at which the clamping device rotates relative to the initial angle. The inspection tool and method for measuring the angle of the bearing bush oil hole disclosed in the application can directly measure the angle of the bearing bush oil hole, with high precision and fast 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 pad. 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 l...
