Problems solved by technology

When the hoop, gauge rod and indicator are fixed together, the detection can only be done on a small vertical plane, and the hoop is easy to rotate around the vertical support, so it is difficult to ensure that the two gauge rods can be kept on the same vertical plan...

Abstract

The invention discloses a device for measuring the verticality. The device is provided with a horizontal base and a vertical support, wherein the vertical support is provided with a benchmark detection mechanism and a declination detection mechanism. The device is characterized in that the vertical support is provided with a vertical bar-shaped through hole; a horizontal positioning rod in the declination detection mechanism is arranged on the vertical support, and extends out of the vertical bar-shaped through hole; the declination detection mechanism passes through the vertical bar-shaped through hole, and a sliding body of the declination detection mechanism is provided with a horizontal through hole; and a measuring rod is inserted at one end of the horizontal through hole, a dial gauge is inserted at the other end of the horizontal through hole, and a detection head of the dial gauge is contacted with the measuring rod. The measuring method comprises the correction method and the detection method. The device and the method have the advantages of making correction detection more convenient, improving the detection accuracy, easily measuring vertical faces of structures in different shapes, and meeting the detection requirements on various workpieces.

Description

technical field [0001] The invention belongs to the technical field of tool detection, and in particular relates to a perpendicularity measuring tool and a measuring method thereof. Background technique [0002] In the machinery manufacturing industry, the quality characteristic parameter of "perpendicularity" is often tested on the workpiece, such as a square and a feeler gauge, or a square is used to estimate the light gap based on experience. The verticality error measured in this way is very large. In response to this dilemma, there have been corresponding verticality testing tools, such as the verticality testing tool provided by Patent No. 93213164.6, which is provided with a horizontal base on which a vertical support is fixed, and two indicator gauges are installed on the vertical support. As the reference detection mechanism and the deviation detection mechanism respectively, the detection accuracy of verticality can be improved through this structure, but the two ...
