Description
Technical Field
The invention belongs to the technical field of metering, and particularly relates to a measuring tool and a measuring method for measuring the thickness of a sound insulation layer.
Background
The inner wall of the armored vehicle body is covered with a flexible sound insulation layer, and when the thickness of the armored vehicle body reaches the standard, the influence of noise on passengers in the vehicle can be effectively reduced. The soundproof layer is made of flexible materials, is very easy to deform, and does not have a proper means to measure the thickness of the soundproof layer at present.
The puigging area is generally great, and is flexible material. If a measuring tool such as a ruler is adopted, the measuring range is severely limited, and the thickness of the edge position can only be measured. By adopting the measuring tools such as the caliper, the effective measuring range is still concentrated on the edge position, and meanwhile, the position is deformed due to the force applied to the measuring part by the measuring tools, so that accurate data of the thickness cannot be obtained.
Disclosure of Invention
The invention aims to provide a measuring tool and a measuring method for measuring the thickness of a sound insulation layer, which can measure at any position of the sound insulation layer and realize accurate measurement of thickness data of the sound insulation layer.
The invention has the technical scheme that the measuring tool for measuring the thickness of the sound insulation layer comprises a needle-shaped measuring scale 1, a measuring slide block 2 and a fastening screw 3; the needle-shaped measuring scale 1 is marked with scale values on the scale body, the bottom of the measuring slide block 2 is a large joint plane, and the measuring slide block 2 is sleeved on the middle part of the periphery of the needle-shaped measuring scale 1 in a sliding mode, can slide up and down and is positioned by fastening screws.
A measuring method for measuring the thickness of a sound insulation layer comprises the following specific steps that the tip of a needle-shaped measuring ruler 1 is completely inserted into the sound insulation layer until the sound insulation layer cannot be extended further; sliding the measuring slide block 2 to enable the bottom large attaching plane to be in full contact with the upper surface of the sound insulation layer; finely adjusting the position of the measuring slide block 2 until the measuring slide block 2 is contacted with the sound insulation layer and locking a fastening screw 3 at a position where deformation is not generated; and reading data on the needle-shaped measuring scale 1, pulling the whole measuring tool out of the sound insulation layer, and reading the corresponding position on the lower surface of the measuring slide block 2 and the needle-shaped measuring scale 1.
The thickness data section measurement method has the advantages that the measurement of the thickness data section can be rapidly completed at any position under the condition that the overall performance of the sound insulation layer is not damaged, and the overall condition of the thickness of the sound insulation layer can be accurately evaluated. The measuring principle is reliable, and the measuring method is simple and effective.
Drawings
FIG. 1 is a schematic diagram of a gauge for measuring the thickness of a sound barrier layer according to the present invention.
Detailed Description
The technical scheme of the invention is further described in detail in the following with the accompanying drawings of the specification.
As shown in fig. 1, a gauge for measuring the thickness of a soundproof layer according to the present invention includes a needle-shaped measuring scale 1, a measuring slider 2, and a fastening screw 3. The needle-shaped measuring scale 1 is marked with scale values on the scale body, the bottom of the measuring slide block 2 is a large joint plane, and the measuring slide block 2 is sleeved on the middle part of the periphery of the needle-shaped measuring scale 1 in a sliding mode, can slide up and down and is positioned by fastening screws.
The invention relates to a method for measuring the thickness of a sound insulation layer, which comprises the following steps of completely inserting the tip part of a needle-shaped measuring scale 1 into the sound insulation layer until the sound insulation layer cannot be continuously penetrated; sliding the measuring slide block 2 to enable the bottom large attaching plane to be in full contact with the upper surface of the sound insulation layer; finely adjusting the position of the measuring slide block 2 until the measuring slide block 2 is contacted with the sound insulation layer and locking a fastening screw 3 at a position where deformation is not generated; and reading data on the needle-shaped measuring scale 1, pulling the whole measuring tool out of the sound insulation layer, and reading the corresponding position on the lower surface of the measuring slide block 2 and the needle-shaped measuring scale 1.
The measurement of the invention adopts a fine needle shape, and the damage influence caused by the penetration of the sound insulation layer is reduced as much as possible. The bottom of the measuring slide block is provided with a plane with a larger area, so that the pressure born by the sound insulation layer in the measuring process can be effectively reduced, the surface deformation quantity of the sound insulation layer is reduced, and the accuracy of the measuring result is ensured.
