Description

Technical Field

[0001] This utility model relates to the field of steel testing equipment, and in particular to an adaptive steel thickness testing caliper. Background Technology

[0002] In the steel production and processing industry, the thickness accuracy and surface flatness of steel are key indicators for measuring product quality.

[0003] Existing testing methods mostly use feeler gauges in conjunction with rulers, or use dedicated large thickness measuring instruments. When using feeler gauges and rulers, the operation steps are cumbersome, requiring multiple measurements and point selections for judgment, which is time-consuming and labor-intensive, and can only obtain discrete point data, making continuous measurement impossible. While dedicated large measuring instruments have high precision, they are bulky and expensive, making them unsuitable for on-site testing and batch sampling scenarios in small and medium-sized enterprises.

[0004] Therefore, there is an urgent need for an adaptive steel thickness testing caliper to improve the efficiency of steel testing. Utility Model Content

[0005] In order to overcome the shortcomings of low measurement efficiency of existing steel testing tools, the technical problem of this utility model is to provide a steel thickness adaptive testing caliper.

[0006] The technical implementation scheme of this utility model is as follows: a steel thickness adaptive detection caliper, comprising a base, a first guide rod, a scale, a first movable seat, a first electric guide rail, a second guide rod, a second movable seat, a second electric guide rail, a third guide rod, a third movable seat, a connecting rod, and a gauge. The first guide rod is fixedly connected to the base, and the first guide rod has a scale. The first movable seat is slidably connected to the first guide rod. The first electric guide rail and the second guide rod are fixedly connected to the first movable seat. The second movable seat is slidably connected to the second guide rod. The first electric guide rail drives the second movable seat. The second movable seat and the second electric guide rail are fixedly connected to the second movable seat. The third movable seat is slidably connected to the third guide rod. The second electric guide rail drives the third movable seat. The connecting rod is rotatably connected to the third movable seat, and the gauge is rotatably connected to the connecting rod.

[0007] More preferably, the first guide rod, the second guide rod, and the third guide rod are located in the Z, Y, and X directions, respectively.

[0008] More preferably, the gauge is a pressure sensor.

[0009] More preferably, it also includes a limit block, a third electric guide rail, an electric cylinder, and a right-angle limit plate. Two mutually perpendicular limit blocks are fixedly connected to the lower left corner of the base. A third electric guide rail is installed on the base, and an electric cylinder is installed on the third electric guide rail. A right-angle limit plate is fixedly connected to the telescopic shaft of the electric cylinder.

[0010] More preferably, it also includes ventilation holes, with multiple ventilation holes provided on the base.

[0011] More preferably, it also includes a ball bearing, with a ball bearing installed at the measuring end of the gauge.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. This utility model, through the coordination of the scale on the first guide rod and the pressure sensor gauge, can not only achieve accurate reading of steel thickness, but also sensitively capture the height fluctuations of the steel surface by the pointer deflection caused by the pressure change at the pressure sensor detection end. When the deflection exceeds the threshold, it is determined to be uneven. Combined with the quantification error of the thickness scale, it can complete the dual high-precision operation of thickness measurement and surface flatness detection, avoiding the reference deviation and efficiency loss caused by switching multiple tools.

[0014] 2. This utility model uses a diagonal clamping structure composed of a limiting block and a right-angle limiting plate, combined with the linkage of a third electric guide rail and an electric cylinder, to quickly and stably position steel of different length and width dimensions without repeated manual adjustments, significantly improving the efficiency of inspection preparation and effectively solving the problems of poor adaptability and time-consuming clamping of traditional inspection tools.

Detailed Implementation

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Example: A steel thickness adaptive detection caliper, such as Figure 1-4 As shown, the device includes a base 1, a first guide rod 2, a scale 201, a first movable seat 3, a first electric guide rail 4, a second guide rod 5, a second movable seat 6, a second electric guide rail 7, a third guide rod 8, a third movable seat 9, a connecting rod 15, and a gauge 16. The first guide rod 2 is fixedly connected to the base 1. The first guide rod 2 has a scale 201. The first movable seat 3 is slidably connected to the first guide rod 2. The first electric guide rail 4 and the second guide rod 5 are fixedly connected to the first movable seat 3. The second movable seat 6 is slidably connected to the second guide rod 5. The first electric guide rail 4 drives the second movable seat 6. The second electric guide rail 7 and the third guide rod 8 are fixedly connected to the second movable seat 6. The third movable seat 9 is slidably connected to the third guide rod 8. The second electric guide rail 7 drives the third movable seat 9. The connecting rod 15 is rotatably connected to the third movable seat 9. The gauge 16 is rotatably connected to the connecting rod 15.

[0022] The first guide rod 2, the second guide rod 5, and the third guide rod 8 are located in the Z, Y, and X directions, respectively, forming a three-dimensional guiding structure. This layout allows the first movable seat 3, the second movable seat 6, and the third movable seat 9 to slide freely in the vertical, horizontal, and longitudinal directions, respectively. With the drive of the first electric guide rail 4 and the second electric guide rail 7, the gauge 16 can be accurately positioned and moved in space, ensuring that the detection end can flexibly cover any position on the steel surface. This provides a foundation for thickness measurement and all-round detection of surface flatness, greatly improving the flexibility and coverage of the detection.

[0023] The gauge 16 uses a pressure sensor as the core detection element. By utilizing the correspondence between pressure changes and the height undulations of the steel surface, it converts surface morphology changes into quantifiable pressure signals. The pointer deflection directly reflects the flatness of the steel surface. When the pressure change causes the pointer deflection to exceed the set range, it can accurately determine the uneven area of ​​the surface.

[0024] Two mutually perpendicular limiting blocks 10 are fixedly connected to the lower left corner of the base 1. Together with the third electric guide rail 11, electric cylinder 12, and right-angle limiting plate 13 on the base 1, they form an adaptive diagonal clamping and positioning system. The third electric guide rail 11 drives the electric cylinder 12 to move laterally, and the telescopic shaft of the electric cylinder 12 drives the right-angle limiting plate 13 to move. This system can quickly and stably clamp steel of different lengths and widths without the need for manual adjustment of the clamps. This structure simplifies the steel clamping process, saves clamping time, ensures that the steel is in a uniform reference position for each inspection, eliminates measurement deviations caused by clamping errors, and effectively improves inspection efficiency and the consistency and reliability of measurement results.

[0025] Multiple ventilation holes 14 are provided on the base 1, which can effectively promote air circulation and prevent the steel from being tightly attached to the base 1 to form negative pressure, making it difficult to disassemble the steel after testing, thus reducing the time and effort consumed by operators to disassemble the steel.

[0026] The measuring end of the gauge 16 is equipped with a ball bearing 17, which converts the sliding friction between the gauge 16 and the steel surface into rolling friction, significantly reducing friction during the testing process. This makes the gauge 16 move more smoothly and fluidly across the steel surface, reducing measurement errors and equipment wear caused by frictional resistance, while also preventing scratches on the steel surface, ensuring stable and reliable test data, and improving the convenience of testing operations and the accuracy of test results.

[0027] During testing, the first movable seat 3 is lifted first, and one corner of the steel is placed in the right-angle positioning area formed by the two limiting blocks 10. Then, the third electric guide rail 11 is activated, and the electric cylinder 12 drives the right-angle limiting plate 1313 to move laterally. When one side of the right-angle limiting plate 13 contacts the steel, the electric cylinder 12 is activated, and its telescopic shaft extends to push the other side of the right-angle limiting plate 13 to fit against the steel. The steel is fixed by diagonal clamping. This structure can adapt to steel with different length and width dimensions.

[0028] In the thickness measurement process, the first moving seat 3 is manually or driven by an external control device to move down along the first guide rod 2 until the detection end of the gauge 16 contacts the top surface of the steel. At this time, the value of the scale 201 on the first guide rod 2 can be directly read to obtain the thickness data of the steel at the current position.

[0029] During surface flatness testing, the control system activates the first electric guide rail 4 and the second electric guide rail 7, respectively driving the second moving seat 6 along the Y-axis and the third moving seat 9 along the X-axis. This, in turn, causes the gauge 16 to move across the steel surface in a two-dimensional plane (similar to a grating scanning path). The gauge 16 uses a pressure sensor, with its sensing end in direct contact with the steel surface. When there are height variations on the steel surface, the pressure on the sensing end changes accordingly, causing the pointer of the gauge 16 to deviate. When the deviation exceeds a certain range, the steel surface is determined to be uneven, and the guide rail movement stops. The steel thickness at that location can be accurately read through the scale 201 on the first guide rod 2. By comparing this thickness with the standard thickness, the surface flatness error can be quantified, achieving automated and high-precision surface flatness testing.
