Description

Technical Field

[0001] The utility model mainly relates to the technical field of small-diameter elbow detection, in particular to a small-diameter elbow detection tool. Background Art

[0002] Small-diameter pipe bends refer to pipe fittings made by bending pipes with smaller diameters. Inspection tools are special inspection equipment or tools used to check the size, quality and performance of small-diameter pipe bends. These tools are commonly used in the pipeline manufacturing and maintenance industries to ensure that the size, shape, bending radius, bending angle and other aspects of the pipe bends meet the design specifications and engineering requirements.

[0003] Traditional small-diameter elbow inspection and fixed-length marking methods have many shortcomings, such as low inspection efficiency, poor accuracy, and complex operation. Common inspection methods include manual measurement, electronic measurement, and mechanical measurement, but these methods all have limitations to varying degrees. For example, manual measurement has large errors and is significantly affected by human factors. Electronic measurement equipment is expensive and has high maintenance costs. Mechanical measurement has problems such as complex structure and inconvenient operation. Many different types of elbows need to be measured with different positioning inspection tooling during the inspection process. In addition, different tooling needs to be replaced when inspecting the angle, length, and levelness of the same elbow. This is not only inconvenient to operate, but frequent tooling changes can also easily cause errors, reduce elbow inspection efficiency, and increase costs. Utility Model Content

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] A small-diameter bent pipe detection tool includes a positioning detection mechanism, which includes a mold base with multiple guide rails and multiple circular holes. A bottom positioning column and two first positioning columns are installed on the mold base by bolts. The bottom positioning column is located at the side edge of the upper surface of the mold base, and the two first positioning columns are distributed in a mirror-symmetrical manner. A second positioning column is provided near one side of each of the first positioning columns, and the two second positioning columns are distributed in a mirror-symmetrical manner.

[0007] Furthermore, a first scribing block is provided on one side close to each of the first positioning posts, and the first scribing block moves along the length direction of the first positioning posts.

[0008] Furthermore, each of the first scribing blocks is in sliding connection with the track on the mold bottom plate.

[0009] Furthermore, a second scribing block is provided on one side close to each of the second positioning posts, and the second scribing block moves along the length direction of the second positioning posts.

[0010] Furthermore, each of the second scribing blocks is in sliding connection with the track on the mold bottom plate.
