[0002] Currently, the wall thickness difference of processed materials is measured using a special tooling. This tooling is large in size and occupies a large area. After the materials are processed, a special person needs to push them to a fixed area for testing. After testing, the materials need to be pushed to the next processing area by another special person. This results in high labor intensity. In addition, the tooling is complex in structure, large in size, and has high manufacturing costs. The testing site is also greatly limited. Considering all aspects, a new type of wall thickness difference gauge needs to be designed. Utility Model Content

[0012] Furthermore, a pad is provided at the hinge point between the measuring rod 2 and the main body.

[0013] Furthermore, the distance from the positioning block 3 to one end of the fork-shaped structure at the front end of the body 4 is the distance from the measuring point to the opening of the part to be measured.

[0014] Furthermore, during measurement, one end of the fork-shaped structure at the front end of the main body 4 is located outside the part to be measured, and the measuring rod 2 extends into the interior of the part to be measured.

[0022] (1) Steel ball 1, there are two of these components, one on the measuring rod 2 and one on the body 4. The wall thickness is measured by sliding in contact with the outer and inner surfaces of the material.

[0023] (2) Measuring rod 2, which is a movable part. The measuring rod moves through shaft 12 and is assisted by spring 5 to measure the material wall thickness difference.

[0024] (3) Positioning block 3, determine the measurement position L according to the requirements.

[0025] (4) Body 4: This component contacts the outer surface of the material and serves as the measurement benchmark for inspecting the thickness difference of the inner surface. The front end is configured with a fork-shaped structure, and one side of the fork-shaped structure is configured as an inwardly flipping L-shape.

[0026] (5) Spring 5, because the measuring rod 2 is a moving part, the wall thickness measurement range is achieved by the spring during measurement.

[0027] (6) Screw 6 is used to fix spring 5.

[0028] (7) Measuring plate 7, which has engravings and can obtain accurate values ​​of wall thickness difference.
