Description

Technical Field

[0002] Special threaded pipes are used to connect two steel pipes, and are mainly used in oil pipelines and other occasions. There are extremely high control requirements for the diameter, pitch, tooth height, taper and other dimensions of the pipe threads. Therefore, it is necessary to conduct data testing on the product to verify whether the product meets the standards.

[0003] The existing technology is mostly manual handheld caliper measurement, which uses calipers to measure the pipe size data. The disadvantages are: 1. There are many measurement points, the manual work intensity is high, and it is easy to cause visual fatigue. 2. There is a risk of inaccurate measurement. 3. There are cumbersome and complicated data records. 4. The measurement efficiency is extremely low.

[0004] Moreover, the existing detection efficiency is low, and due to factors such as the movement of the handheld detector or caliper relative to the detection target and insufficient rotation angle of the handheld detection, the final detection result may be insufficiently accurate and incomplete.

[0020] The technical effects of the pipe end thread detection device in this application are as follows:

[0021] It is worth noting that the key of the utility model is to provide a detection device in the form of a mechanical structure, using a profile scanner to perform profile scanning on the threads at the end of the pipe during the production process, so as to replace the process of manually surrounding the scanning mechanism around the pipe for detection, avoid carrying the pipe, etc., so as to reduce the intensity of manual labor and improve the detection efficiency.
