Description

Technical Field

[0001] The utility model relates to the technical fields of steel pipe manufacturing and quality inspection, and particularly relates to an adjustable steel pipe weld height measuring ruler. Background Technique

[0002] A weld measuring ruler is a measuring tool used to measure the height of a weld. Place the measuring surface of the weld ruler on a plane and press the zero key as the basic calibration value. After the zeroing operation, place the weld to be measured between the two measuring surfaces, gently move the tip of the ruler so that the measuring surface contacts the highest point of the weld, and the displayed value is the height dimension value of the steel pipe weld.

[0003] At present, the weld measuring rulers used in enterprise inspections are generally only suitable for measuring the height dimensions of flat welds. Since the steel pipe weld extends along the axial direction of the steel pipe as the longitudinal weld, and the width of the measuring ruler is fixed and non-adjustable, and the actual surfaces on both sides of the weld are arc-shaped, the measurement standard for the height of the steel pipe weld is the two bottom lines of the weld width, and the horizontal plane is perpendicular to the highest point of the weld bulge. Therefore, the existing weld measuring rulers have obvious detection defects: the weld widths of steel pipes of different specifications are also different. Since the width of the weld measuring ruler is non-adjustable, it cannot be placed on the two bottom lines of the weld width, and can only be placed on the arc surface of the steel pipe, which will be lower than the horizontal plane of the bottom line of the weld width, resulting in a higher error in the weld height. This situation is more obvious when the diameter of the steel pipe is smaller and the arc is larger, which brings certain adverse effects to the use process. To solve the deficiencies of the existing technology, we propose an adjustable steel pipe weld height measuring ruler. Content of the Utility Model

[0004] The main purpose of the utility model is to provide an adjustable steel pipe weld height measuring ruler, which can effectively solve the problems in the background technique.

A 90° clamp is arranged on the right side of the 90° groove ruler frame. A plurality of groups of installation screw holes are evenly arranged inside the 80° clamp and the 90° clamp. Positioning tips are arranged at the lower ends of the 80° clamp and the 90° clamp. A first slot is arranged inside the 80° clamp. A second slot is arranged inside the 90° clamp. Hand-tightening screws are arranged between the 80° clamp and the installation screw holes, and between the 90° clamp and the installation screw holes.
