Description

Welding inspection ruler inspection device Technical Field The invention relates to the technical field of measuring devices, in particular to a welding inspection ruler inspection device. Background The welding inspection ruler is a measuring device for inspecting parameters such as weld bead width, height, welding gap, groove angle, undercut depth and the like of a welding piece by utilizing the principles of line and vernier measurement and the like, and mainly comprises three parts of a main ruler, a sliding ruler and an oblique ruler, is suitable for measuring relevant data of products and parts with higher welding quality requirements, such as a boiler, a pressure container and the like, and is a necessary measuring tool for welders. The measuring tool is listed in JB/DQ9004-87 industrial boiler quality standard of the electric bureau of the mechanical industry, and welding inspection content comprises inspection of materials, tools, equipment, technical process and finished product quality used in the whole production process from drawing design to product manufacture, including inspection before welding, inspection in the welding process and inspection of finished products after welding, and is a measuring tool which has important significance for safe production and is widely applied. The comprehensive measuring device of the welding inspection ruler is mainly used for verification and calibration of the welding inspection ruler of the measuring appliance, quantitative analysis and qualitative judgment of each measuring parameter of the welding inspection ruler are carried out, and magnitude transmission is carried out. The structural form of the welding inspection ruler is divided into I type, II type, III type and IV type, wherein the III type welding inspection ruler comprises a main ruler 103, a height ruler 101, a ruler 102, an undercut depth ruler 105 and a multipurpose ruler 104, wherein the two sides of the main ruler 103 are provided with 45-degree unfilled corners, the height ruler 101 can slide, when the welding leg concavity and convexity of a corner welding seam of a corner welding test plate are carried out, the two 45-degree unfilled corners are aligned with the two sides of a welding seam test piece, the sliding height ruler 101 is contacted with a measuring point, and the indication value of the height ruler 101 on the ruler 102 is measured data. The height gauge 101 and the undercut depth gauge 105 are respectively provided on the main gauge 103 by locking means. The multi-purpose ruler 104 includes a width ruler 1041, an angle ruler 1042, and a clearance ruler 1043. The verification of the welding test ruler is carried out strictly according to the national metrology verification rule JJG 704-2005 welding test ruler, and the main verification project is 12, and the used standard appliance and matched equipment are 10 major classes and 25 minor classes. The preparation work before the verification work starts is very tedious, and because most of the used standard equipment is shared with other measurement standards, a great deal of time and effort are consumed in searching and assembling, and the phenomenon that the whole experiment workbench is fully occupied by the standard instrument for verification often occurs. In addition, various standard appliances are independently placed and have no fixed positions, so that the stability is poor in the use process, and when different operators read a measurement system which is relatively lack of stability, the measurement error introduced by human factors is large, so that the verification accuracy is greatly influenced. In addition, because the standard appliances are huge in quantity and often share with other projects, the laboratory cannot be brought out, so that the welding inspection ruler can only adopt a sample conveying inspection mode, namely, a customer sends a sample to the laboratory, the sample is taken away after the inspection is finished, the sample cannot be used by the customer during the laboratory, and the requirements of on-site inspection and instant inspection of the customer cannot be met. Moreover, the welding inspection ruler has low inspection cost, and the personnel equipment, equipment investment and detection time are not proportional to the project income seriously, so that a large amount of inspection resources are wasted. Disclosure of Invention The technical problem to be solved by the invention is to provide the welding inspection ruler inspection device, so that the problems that a standard appliance is poor in stability in the use process, a measurement error caused by human factors is large and cannot be carried, and verification resources are wasted are solved, the whole device is convenient to take, place and carry, errors caused by the human factors are reduced, the detection efficiency is improved, the detection time is shortened, and the detection precision is improved. In order to solve the
