Description

Technical Field

[0001] This utility model relates to the technical field of steel strip thickness measuring devices, and more specifically, to a steel strip thickness dimension detection device. Background Technology

[0002] Thickness measuring devices are required during the processing of steel strips. There are two types of thickness measuring devices: non-contact thickness gauges and contact thickness gauges. To improve the convenience of inspection, ultrasonic thickness gauges are generally used. When using them, the ultrasonic thickness gauge is held in hand, and the inspection head is placed against the steel strip to be inspected. The probe then emits ultrasonic pulses to the steel strip being inspected. The sound waves propagate inside the material and are reflected at the bottom surface. The reflected echo is received by the probe, and after calculation by the machine, the thickness is displayed on the screen.

[0003] A search revealed a prior art device for detecting the thickness of steel strip processing, patent publication number CN222317970U. The specification states that a clamping unit is provided. Before use, the steel strip is pulled through the top of the idler roller, and then the slider is controlled to move, causing the pressure roller to descend. The pressure roller and the idler roller work together to clamp the steel strip. A servo motor is used to tighten the steel strip, ensuring its stability during the detection process and preventing vibrations from affecting the measurement results.

[0004] However, in actual use, if the surface of the steel strip is rough and has impurities attached, the adhesion effect of the steel strip surface of the detection head will be poor, which will not only reduce the detection accuracy, but also wear down the surface of the detection head and reduce its service life. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a steel strip thickness detection device to solve the problem that if the surface of the steel strip is relatively rough and has impurities attached, the adhesion effect of the detection head to the steel strip surface is poor, which not only reduces the detection accuracy, but also wears on the surface of the detection head and reduces its service life.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a steel strip thickness detection device, including a detector, the detector being connected to a detection head via a lead wire, a protective cover being fitted over the detection head, a storage groove being provided at the end of the protective cover away from the detection head, a cleaning brush being slidably connected inside the storage groove, two placement slots being provided inside the cleaning brush, a placement block being detachably connected inside the placement slot, and the placement block being fixedly connected to the inner wall of the storage groove.

[0007] The detection head is externally hinged with two connecting rods, each with a sliding groove inside. The protective cover is fixedly connected to two connecting rods at the end away from the storage groove, and the other end of each connecting rod is fixedly connected to a compression plate. An elastic element is sleeved on the outside of each connecting rod.

[0008] The inner wall of the placement slot has slots on both the front and rear sides. Two limiting blocks are fixedly connected to the inner wall of the slot. An insert block is inserted into the inside of the slot, and two limiting grooves are opened on the outside of the insert block.

[0009] The extrusion plate is slidably connected inside the groove, and the connecting rod is slidably connected inside the groove.

[0010] One end of the elastic element is fixedly connected to the slide groove, and the other end of the elastic element is fixedly connected to the extrusion plate.

[0011] The insert is a slanted block structure that slides against the inner wall of the placement groove, and the insert is inserted into the inside of the slot.

[0012] The insert block slides against the outside of the limiting block, and the limiting block fits into the inside of the corresponding position limiting groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In the above solution, by covering the outside of the detection head with a protective cover, the detection head can be protected when not in use. When in use, the detection points can be cleaned by the cleaning brush inside the protective cover, resulting in higher detection accuracy. This not only extends the service life of the detection device but also improves the detection quality, making it more economical to use. Attached Figure Description

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] Example 1: Please refer to Figures 1 to 5 This utility model provides a technical solution: a steel strip thickness detection device, including a detector 1, a detector head 2 connected to the detector 1 via a lead wire, a protective cover 3 covering the outside of the detector head 2, the protective cover 3 protecting the detector head 2, when the detector head 2 is not in use, the protective cover 3 is fitted on the detection end of the detector head 2, when the detector head 2 is in use, the protective cover 3 can be removed from the detection end of the detector head 2 and fitted to the other end of the detector head 2, so that the protective cover 3 can be placed, a storage groove 4 is provided at the end of the protective cover 3 away from the detector head 2, a cleaning brush 5 is slidably connected inside the storage groove 4, the storage groove 4 provides installation space for the cleaning brush 5, the cleaning brush 5 is used to clean the surface of the steel strip, two placement grooves 6 are provided inside the cleaning brush 5, and a placement block 7 is fixedly connected to the inner wall of the storage groove 4, the placement block 7 is detachably connected inside the placement groove 6, so that the cleaning brush 5 can be conveniently installed.

[0024] When testing is required, the protective cover 3 is removed from the testing end of the testing head 2 and placed against the other end of the testing head 2. Then, the cleaning brush 5 is placed against the testing area of ​​the steel strip, and the testing area can be cleaned with the cleaning brush 5. After cleaning, the testing end of the testing head 2 is placed against the testing area of ​​the steel strip, resulting in higher testing accuracy. After testing, the protective cover 3 is placed back on the testing end of the testing head 2 to protect the testing head 2. This not only extends the service life of the testing device but also improves the testing quality, making it more economical to use.

[0025] Example 2: Based on Example 1, in order to achieve stable connection between the protective cover 3 and the detection end of the detection head 2, two connecting rods 1 8 are hinged to the outside of the detection head 2. The connecting rods 1 8 have a sliding groove 9 inside. Two connecting rods 2 11 are fixedly connected to the end of the protective cover 3 away from the storage groove 4. The connecting rods 2 11 are slidably connected inside the sliding groove 9. The sliding groove 9 limits the connecting rods 2 11, allowing them to slide smoothly. An extrusion plate 10 is fixedly connected to the other end of the connecting rods 2 11. The extrusion plate 10 is slidably connected inside the sliding groove 9. The sliding groove 9 limits the extrusion plate 10, allowing it to slide smoothly. An elastic element 12 is sleeved on the outside of the connecting rods 2 11. One end of the elastic element 12 is fixedly connected to the sliding groove 9, and the other end is fixedly connected to the extrusion plate 10.

[0026] When the protective cover 3 needs to be removed from the detection end of the detection head 2, the protective cover 3 can drive the connecting rod 11 to move outward, so that the connecting rod 11 can pull the extrusion plate 10 to compress the elastic element 12 and cause deformation. Under the limit of the connecting rod 11, the connecting rod 11 can drive the connecting rod 8 to rotate outside the detection head 2. When the protective cover 3 is placed at the other end of the detection head 2, the elastic element 12 can perform a reset movement, so that the elastic element 12 can push the extrusion plate 10 to move inward, so that the extrusion plate 10 can pull the protective cover 3 to fit tightly against the detection head 2 through the connecting rod 11, so that the protective cover 3 has high placement stability. Conversely, by putting the protective cover 3 on the detection end of the detection head 2, the detection head 2 is protected by the protective cover 3 under the action of the elastic element 12, so that the service life of the detection head 2 is longer.

[0027] Example 3: Based on Example 2, in order to facilitate the replacement of the cleaning brush 5, slots 13 are provided on both the front and rear sides of the inner wall of the placement groove 6. Two limiting blocks 14 are fixedly connected to the inner wall of the slot 13. A plug 15 is inserted into the inside of the slot 13. The plug 15 has an inclined block structure and slides against the inner wall of the placement groove 6, so that the placement groove 6 can easily squeeze the plug 15 to produce deformation. The plug 15 is inserted into the inside of the slot 13, so that the plug 15 is limited. Two limiting grooves 16 are provided on the outside of the plug 15. The plug 15 slides against the outside of the limiting block 14, so that the plug 15 is squeezed to produce deformation. The limiting block 14 fits against the inside of the corresponding limiting groove 16, so that the plug 15 is limited again.

[0028] When the cleaning brush 5 needs to be installed, the cleaning brush 5 is slid into the storage slot 4, allowing the placement block 7 to slide into the placement slot 6. This allows the insertion block 15 to slide against the inner wall of the placement slot 6, causing the insertion block 15 to be compressed and deformed. When the placement block 7 is in contact with the inner wall of the placement slot 6, the insertion block 15 performs a reset movement, allowing it to slide into the slot 13 and slide against the limiting block 14. When the insertion block 15 fills the inside of the slot 13, the limiting block 14 fits against the inside of the limiting slot 16, thus facilitating the installation of the cleaning brush 5. Conversely, it can be easily disassembled.

[0029] The working process of this utility model is as follows:

[0030] When the thickness of the steel strip needs to be tested, the cleaning brush 5 is slid into the storage groove 4, allowing the placement block 7 to slide into the placement groove 6. This causes the insertion block 15 to slide against the inner wall of the placement groove 6, resulting in deformation. Once the placement block 7 is in contact with the inner wall of the placement groove 6, the insertion block 15 returns to its original position, sliding into the slot 13 and sliding against the limiting block 14. Once the insertion block 15 fills the slot 13, the limiting block 14 engages with the inside of the limiting groove 16, facilitating the installation of the cleaning brush 5. Subsequently, the protective cover 3 is removed from the detection end of the detection head 2, causing the connecting rod 11 to move outwards. This causes the connecting rod 11 to pull the extrusion plate 10, compressing the elastic element 12 and causing deformation. The deformation occurs at the limiting position of the connecting rod 11. The connecting rod 11 drives the connecting rod 8 to rotate outside the detection head 2. When the protective cover 3 is placed at the other end of the detection head 2, the elastic element 12 can perform a reset movement, which pushes the extrusion plate 10 to move inward. This allows the extrusion plate 10 to pull the protective cover 3 tightly against the detection head 2 through the connecting rod 11, resulting in high stability of the protective cover 3. Then, the cleaning brush 5 is attached to the detection area of ​​the steel strip, and the detection area can be cleaned with the cleaning brush 5. After cleaning, by attaching the detection end of the detection head 2 to the detection area of ​​the steel strip, the detection accuracy is high. After the detection is completed, the protective cover 3 is put on the detection end of the detection head 2 again to protect the detection head 2. This not only extends the service life of the detection device but also improves the detection quality, making it more economical to use.
