[0001] This utility model relates to the field of rivet detection technology, and in particular to a tool for measuring the size of rivets. Background Technology
[0002] In industrial quality control, accurate measurement of rivet dimensions is crucial for ensuring the final product assembly quality and structural stability. Dimensional inspection of fasteners like rivets typically relies on traditional ruler-based methods, where operators directly measure randomly selected samples one by one with a ruler. While this method seems intuitive and simple, it's suitable for quickly obtaining preliminary data. This direct measurement method allows for rapid assessment of whether the rivet's basic dimensions meet standard requirements, providing a basis for immediate adjustments on the production line.
[0003] However, this traditional measurement method has revealed its shortcomings in practical applications. When using a ruler for measurement, the unavoidable slight tremors of the hand often lead to inaccurate readings, affecting the reliability of the measurement results.
[0004] Therefore, it is necessary to provide a tool for measuring the dimensions of rivets to solve the above problems. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please refer to the following: Figures 1 to 4A tool for measuring the dimensions of a rivet, comprising:
[0024] Place block 1;
[0025] The measuring component includes a sliding plate 201, a calibration component, and a reading component. The surface of the placement block 1 is provided with a 203. The sliding plate 201 is slidably connected to the inner wall of the 203. The surface of the sliding plate 201 is provided with a scale 202. The calibration component is used to align one end of the sliding plate 201 with the pull stud. The reading component is used to facilitate reading the length of the pull stud.
[0026] In the specific implementation process, firstly, the calibration plate 301 is rotated around the first bolt 302 as the axis, so that it is away from directly above the placement block 1. Then, the pull stud is placed into the placement block 1. Next, the calibration plate 301 is rotated to directly above the placement block 1 and aligned with one end of the pull stud. At this time, the sliding plate 201 will move towards the pull stud in the sliding groove 203 until the calibration plate 301 and the pull stud are completely in contact. One end of the sliding plate 201 automatically aligns with the pull stud position. Then, the abutment plate 401 is pushed, so that the second bolt 402 slides in the sliding groove 403 until the abutment plate 401 contacts the other end of the pull stud. At this time, the pointer on the second bolt 402 points to the scale 202 on the surface of the sliding plate 201, which visually displays the length of the pull stud. The whole process does not require holding a ruler, avoiding measurement errors caused by hand tremors. At the same time, the dual positioning of the calibration plate 301 and the abutment plate 401 ensures that the measurement results are accurate and highly repeatable, greatly improving the sampling efficiency.
[0027] refer to Figures 1 to 4 As shown, the interior of the placement block 1 is provided with a guide groove.
[0028] In the above embodiment, when the sliding plate 201 slides in the sliding groove 203 inside the placement block 1, the guide groove plays a role in stabilizing and guiding the pull pin, preventing the pull pin from deviating, and ensuring that the pull pin and the sliding plate 201 are always in the same straight line, thereby ensuring the alignment of the pull pin and the sliding plate 201 during the measurement process and avoiding measurement deviation.
[0029] refer to Figures 1 to 4 As shown, the calibration assembly includes a calibration plate 301 and a first bolt 302. The first bolt 302 is threadedly connected to one end of the sliding plate 201, and the calibration plate 301 is rotatably connected to the circumferential surface of the first bolt 302.
[0030] In the above embodiment, the calibration plate 301 is connected to the sliding plate 201 by the first bolt 302. During operation, the calibration plate 301 only needs to be manually rotated to fit one end of the pull stud. At this time, the sliding plate 201 will slide along the sliding groove 203 towards the pull stud until one end of the sliding plate 201, i.e. the scale 0 point, is completely aligned with the end face of the pull stud, thus achieving precise positioning and avoiding measurement errors caused by the initial position deviation of the sliding plate 201. The simple rotation operation of the calibration plate 301 can complete the positioning without complex adjustments, significantly improving calibration efficiency and measurement accuracy.
[0031] refer to Figures 1 to 4 As shown, the reading component includes a back plate 401 and a second bolt 402. A sliding groove 403 is provided on the surface of the sliding plate 201. The second bolt 402 is slidably connected to the inner wall of the sliding groove 403. The back plate 401 is threadedly connected to the circumferential surface of the second bolt 402. A pointer is fixedly connected to the surface of the second bolt 402, and the pointer is in contact with the sliding plate 201.
[0032] In the above embodiment, when the abutment plate 401 is pushed, the second bolt 402 slides synchronously in the sliding groove 403. The abutment plate 401 is threadedly connected to the second bolt 402, and the contact position between the abutment plate 401 and the pull rivet can be freely adjusted. When the abutment plate 401 is pressed against the other end of the pull rivet, the pointer on the surface of the second bolt 402 will accurately point to the scale 202 on the sliding plate 201, realizing rapid reading. At the same time, the contact design between the pointer and the scale 202 reduces visual errors. Even if the operator does not look directly at the scale, he can judge the length by the pointer position, which greatly improves the measurement efficiency and reliability.
[0033] refer to Figures 1 to 4 As shown, a fluorescent strip is fixedly connected to the inner wall of the scale 202.
[0034] In the above embodiment, the inner wall of the scale 202 on the surface of the sliding plate 201 is provided with a fluorescent strip. When the light is insufficient, the fluorescent strip will emit a faint light, making the scale line clearly visible. The operator can complete the measurement without additional lighting, which is especially suitable for nighttime operation or poor workshop lighting. At the same time, the fluorescent strip has strong durability and is not easy to fade after long-term use, ensuring that the equipment can work stably under various lighting conditions.
[0035] refer to Figures 1 to 4 As shown, the sliding plate 201, calibration plate 301 and abutment plate 401 are all detachable modular designs.
[0036] In the above embodiments, the sliding plate 201, calibration plate 301 and abutment plate 401 are all modularly designed. When a certain part is worn or damaged, it can be disassembled and replaced individually. For example, after the scale 202 of the sliding plate 201 is worn, the measurement function can be restored simply by replacing the new sliding plate 201, which reduces equipment maintenance costs and downtime. At the same time, the modular structure facilitates transportation and storage, further improving the practicality and economy of the equipment.
[0037] The working principle of the tack dimensional measuring tool provided by this utility model is as follows:
[0038] Through structured design and a precise positioning mechanism, rapid and stable measurement of the pull stud length is achieved. First, the calibration plate 301 is rotated around the first bolt 302 to a position directly above the placement block 1 and against one end of the pull stud. At this point, the sliding plate 201 slides along the sliding groove 203 towards the pull stud until the calibration plate 301 is fully against the end face of the pull stud, ensuring that the 0 point of the scale on the surface of the sliding plate 201 is aligned with one end of the pull stud, completing the initial positioning. Then, the abutment plate 401 is pushed, causing it to slide along the sliding groove 403 and against the other end of the pull stud. The abutment plate 401, via the second bolt 402, drives the pointer to move synchronously, and the pointer eventually points to the scale on the surface of the sliding plate 201. The ruler 202 visually displays the actual length of the pull stud. A fluorescent strip on the inner wall of the ruler 202 ensures clear display of the scale even in low-light conditions, reducing reading errors caused by environmental factors. The contact design between the pointer and the ruler further reduces visual bias, allowing operators to quickly obtain data through the pointer position even without directly looking at the scale. The sliding plate 201, calibration plate 301, and abutment plate 401 are all detachable structures, allowing for individual replacement when worn, eliminating the need for overall maintenance, extending equipment lifespan, and reducing maintenance costs. Through the above process, this invention effectively solves the problem of inaccurate readings caused by hand tremors in traditional measurement methods: the dual positioning mechanism of the calibration plate 301 and abutment plate 401 ensures the stability of the measurement start and end points, avoiding errors caused by hand tremors or viewing angle deviations when manually holding the ruler; the guide groove design within the placement block 1 further ensures the straightness of the measurement trajectory, improving the consistency of repeated measurements; the combined use of the fluorescent strip and pointer significantly optimizes the operating experience under low-light conditions, making the measurement process more efficient and reliable. The overall structure is simple and practical, suitable for industrial sampling inspection, production line quality control and other scenarios, and greatly improves the accuracy of rivet size measurement.
