As an important part widely used in various fields of industry, bent pipe has important uses in the fields of vehicles, petroleum, chemical industry, navigation, aviation and nuclear industry, and its quality may directly affect whether the whole machine or equipment can work normally. safe operation. Therefore, in the actual production of bent pipes, how to efficiently and accurately measure whether the parameters of the produced bent pipes meet the design requirements is of great significance.

The bending forming of elbow pipe is a complex process integrating material nonlinearity, geometric nonlinearity and boundary condition nonlinearity. The influencing factors of this process are complex and the forming quality is difficult to control. At present, in the development and production of complex military products such as aviation and aerospace, the bend measurement after forming is the most effective and direct means to ensure the quality of pipeline manufacturing and realize accurate stress-free assembly.

The difficulty in the measurement of the bent pipe lies in the measurement of parameters such as the bending angle, the position of the inflection point, and the amount of advancement of each section after processing. At present, pipe bending factories mostly rely on manual measurement of dimensional parameters using calipers, protractors and other measuring instruments or three-coordinate measuring instruments. However, the use of conventional measuring instruments for measurement not only has low work efficiency and poor measurement accuracy, but is mostly related to the measurement experience of workers. Although the technology of three-coordinate measuring instruments is relatively mature and the measurement accuracy is high, its essence is to measure the surface of the measured part. The three-dimensional coordinates of a series of point sets, so the measurement workload is large, the efficiency is low, and the equipment price is often high.

Compared with traditional measurement methods, visual measurement has the advantages of non-contact, high precision, fast and convenient, so it can be greatly improved. Inspection accuracy and speed, thereby improving production efficiency. However, there are the following problems in the use of existing measuring equipment: 1. The camera adjustment angle is small, which cannot meet the actual measurement needs; 2. Due to the light of the existing measuring equipment, the obtained photos are not clear, which affects the measurement. Accuracy; 3. In the process of measuring the existing bent pipes, the bent pipes can only be manually placed in batches in the test device, and the measurement efficiency is low. 4. When the existing measuring equipment is used for testing long bend pipes, since the measuring equipment only has an opening at the front side, it is troublesome to place.
