Thickness gauge with replaceable probe and test method

Abstract

The invention relates to a thickness gauge with replaceable probes and a test method. The thickness gauge comprises a mechanical scale, a digital display gaugehead, a scale slide block, a movable U-shaped probe, a fixed U-shaped probe, a needle-shaped probe, a measuring pedestal and a positioning device. The scale slide block is arranged on the mechanical scale. The measuring pedestal and the positioning device are fixed to the two ends of the mechanical scale respectively. The digital display gaugehead is fixed to the scale slide block. In this way, the thickness gauge is formed. The thickness gauge matches the movable U-shaped probe, the fixed U-shaped probe and the needle-shaped probe to meet requirements in different measuring environments. Measuring modes are flexible and changeable. The thickness gauge can measure thickness or depth in different conditions and different positions, such as the thickness of window glass with a window frame, the thickness of a door leaf with a door frame, the thickness of glass on a door leaf, the thickness of a girder web, the thickness of a sheet material with the coarsely cut edge, the thickness of a surface coating, the depth of a slit or a hole. The thickness gauge is simple in structure and low in cost, people can easily learn to use the thickness gauge, and flexible and changeable application methods are provided.

Description

technical field [0001] The invention relates to a thickness measuring instrument with a changeable measuring head and a testing method, which are used for measuring the thickness of window glass with a window frame, the thickness of a door leaf with a door frame, the thickness of glass on a door leaf, the thickness of a steel beam web, and the roughness of edge cutting The thickness of the sheet, the thickness of the surface coating, the depth of the gap or hole, etc. Background technique [0002] At present, there are many instruments and equipment used to measure thickness dimensions, such as micrometers, vernier calipers, tape measures, etc. However, the measurement methods of these measuring devices are relatively single, and the conditions of use also have certain limitations. For example, micrometers and vernier calipers are limited by the size of the measuring tool itself, and can only measure the thickness of the edge of the plate; the accuracy of the tape measure i...

Problems solved by technology

However, the measurement methods of these measuring equipment are relatively single, and the conditions of use also have certain limitations.

For example, micrometers and vernier calipers are limited by the size of the measuring tool itself, and can only measure the thickness of the edge of the plate; the accuracy of the tape measure is not high, and the edge scale is easy to wear

For example, when it is necessary to measure the thickness of the window glass with the window frame, the thickness of the door leaf with the door frame, the thickness of the glass on the door leaf, the thickness of the web of the steel beam, the thickness of the plate with rough edge cutting, the depth of the hole, etc., the commonly used measuring tools are as follows: Micrometers, vernier calipers, and tape measures cannot meet the needs of measurement due to their own structural limitations
