Weld groove angle inspection rule

Abstract

The invention belongs to the technical field of measuring tools, and provides a weld groove angle inspection rule. The weld groove angle inspection rule comprises a measuring assembly and a display assembly used for displaying an angle measured by the measuring assembly, wherein the measuring assembly comprises a fixed plate, a first movable plate, a second movable plate and a third movable plate, the first movable plate is rotatably connected with the fixed plate, and the second movable plate is rotatably connected with the first movable plate; one ends, away from the first movable plate, of the third movable plate and the second movable plate are rotatably connected; and the other end of the third movable plate is rotatably connected with the right end of the fixed plate. By arranging the movable plates which can be rotatably connected with one another, the weld groove angle inspection rule can be folded; and through setting calibration mark lines, the operator can measure the length of the weld corners, thereby solving the problems that a welding inspection rule has single structure, the device is complicated, the groove angle between two adjacent plates cannot be measured after welding members are assembled and the operator has high difficulty in operation during use.

Description

technical field [0001] The invention belongs to the technical field of measuring tools, in particular to a weld bevel angle inspection ruler. Background technique [0002] In China, the M306041 type is the most widely used welding inspection ruler. It is mainly composed of three parts: main ruler, sliding ruler and oblique ruler. It is a special measuring tool used to measure the angle of the groove of the weldment, the width and height of the weld, and the welding gap. It is suitable for products and components that require high welding quality, such as boilers, pressure vessels, etc. Most welding inspection rulers are made of stainless steel, with reasonable structure, beautiful appearance, convenient use and wide applicability. They are necessary measuring tools for welders. [0003] The welding inspection ruler in the prior art has a single structure, complex device, inconvenient to carry, and cannot measure the bevel angle between two adjacent plates after the weldmen...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a welding seam groove angle inspection ruler, which aims to solve the problem that the welding inspection ruler in the prior art has a single structure, a complicated device, inconvenient carrying, and cannot measure the slope between two adjacent plates after the weldment is assembled. The mouth angle makes the operation difficult for the operator when using it
