Description

Flange joint precision measurement location processingequipment Technical Field The invention belongs to the technical field of flange joint measurement, and particularly relates to a flange joint precise measurement positioning processing device. Background The flange joint is used as a core component for pipeline connection and equipment butt joint, is widely applied to the fields of high-end equipment such as petrochemical industry, aerospace, semiconductor manufacturing, ship engineering and the like, and the machining precision of the flange joint directly determines the sealing performance, the bearing capacity and the system operation stability of a connecting part. Under extreme working conditions such as high pressure, high temperature, strong corrosion and the like, small deviations of key dimensions such as end surface flatness, bolt hole site Precision (PCD), internal diameter coaxiality and the like of the flange joint can cause fluid leakage, structural stress concentration and even serious safety accidents, so that the processing precision requirements of the industry on the flange joint are improved to be in a micron level or even in a submicron level. In the precision measurement and processing procedures of the flange joint, the accurate positioning of the workpiece is a core premise for guaranteeing the accuracy of measured data and the processing precision. The positioning scheme commonly adopted in the current industry mainly depends on two traditional modes of external contour positioning or internal reference positioning, although basic positioning requirements can be met, a remarkable technical short plate exists in practical application, and in the design logic of the existing positioning assembly, a front centering calibration module is generally lacking, so that the flange joint cannot realize automatic centering and reference calibration after being placed on a workbench. Operators can only manually and roughly position by experience or simple auxiliary tools, so that the complexity of manual operation is greatly increased, the consistency of positioning accuracy is more difficult to ensure, the deviation is easily generated between the actual positioning reference and the theoretical reference of the flange joint due to the lack of a systematic centering mechanism, the deviation can be directly transmitted to a subsequent measuring link, and errors occur in data such as dimension measurement, form and position tolerance detection and the like, so that the processing quality control is seriously affected. Meanwhile, the manual centering process is long in time consumption, the efficiency of the whole processing flow is reduced, particularly in a mass production scene, the defect can be further amplified, the production takt and the productivity are restricted to be improved, in addition, the traditional positioning mode has higher dependence on the skill level of operators, the fluctuation of the positioning precision can be further aggravated due to the operation habit and experience difference of different operators, the standardized and reproducible processing flow is difficult to form, and the stable management and control of the product quality are not facilitated.
