[0002] Generally speaking, the position degrees of structural parts that are mutually referenced mainly include length, flatness, symmetry, etc., such as figure 1 The position of the measured workpiece 1 and the measured workpiece 2 cannot be fully measured with commonly used measuring instruments
At present, the measurement of this structural product is completed by using a flexible three-coordinate measuring arm. The preparation cycle for measurement is long, the measurement cycle is long, the technical requirements for workers are high, the selection of measurement benchmarks is difficult, and there are many transfer links, which affect the measurement of products. precision

Embodiment Construction
[0023] The present invention is further illustrated below in conjunction with the accompanying drawings and examples.
[0024] like Figure 4 and Figure 5 As shown, the measuring tool is composed of lifting ring (1), hanging beam (2), locator 1 (3), locator 2 (4), locator 3 (5), and locator 4 (6). Set the lifting ring (1) in the middle of the hanging beam (2), set the locator 1 (3) and the locator 2 (4) on the left side of the hanging beam (2); set the locator on the right side of the hanging beam (2) 3 (5) and locator 4 (6), where locator 1 (3) is a plane baffle, used to position the measuring tool and the workpiece (measured workpiece 1 (8) and measured workpiece 2 (9) ), the locator 2 (4) and the locator 3 (5) have a "concave" structure, and each working surface is a plane, which is used to measure the measured workpiece 1 (8) and the measured workpiece 2 (9 ), the positioner 4 (6) is a conical structure, including a ball head, and the working surface is a spherical sur...

The invention provides a measuring tool and method for structural part location degrees acted as mutual references. The measuring tool is composed of a hoisting ring, a hanging beam and four locators. The hoisting ring is arranged in the middle of the hanging beam, and the first locator and the second locator are arranged on the left side of the hanging beam. The third locator and the fourth locator are arranged on the right side of the hanging beam. The first locator is a plane baffle, the second locator and the third locator are of a concave-shaped structure, and all the working surfaces are planes. The fourth locator is of a conical structure and comprises a bulb, and the working surface is a spherical surface. According to the measuring tool, one certain end face of a measured workpiece is used as the reference, and the gaps between the working surfaces of the four locators and the measured workpiece are measured through a mil sheet, so that correctness of the location degrees such as the distance, the flatness and the degree of symmetry of structural parts is judged.
Description
technical field [0001] The invention relates to a measuring tool and a measuring method for the position degree of a structural part as a mutual reference, and belongs to the technical field of surveying and mapping. Background technique [0002] Generally speaking, the position degrees of structural parts that are mutually referenced mainly include length, flatness, symmetry, etc., such as figure 1 The position of the measured workpiece 1 and the measured workpiece 2 cannot be fully measured with commonly used measuring instruments. At present, the measurement of this structural product is completed by using a flexible three-coordinate measuring arm. The preparation cycle for measurement is long, the measurement cycle is long, the technical requirements for workers are high, the selection of measurement benchmarks is difficult, and there are many transfer links, which affect the measurement of products. precision.
