[0002] The transverse thickness variation of steel strip generally refers to the difference in thickness across the strip (i.e., its width). Steel strip is a long, strip-shaped metal material typically made from steel or iron through a rolling process. During the production process, due to various factors, such as the mill's rolling process, equipment accuracy, and the material's inherent properties, the strip may exhibit uneven thickness across its width. Detecting transverse thickness variation of steel strip is a critical step in ensuring product quality and improving production efficiency.

[0003] With the rapid development of the steel industry, the requirements for accuracy and efficiency in strip transverse thickness measurement are increasing. While the current mainstream detection technologies, such as mechanical and ultrasonic methods, have met these requirements to a certain extent, they still have some shortcomings and issues. For example, mechanical methods are cumbersome to operate and slow to measure, resulting in low overall efficiency. Their accuracy is affected by the operator's skill and experience, and is subject to certain subjectivity. Ultrasonic methods are easily affected by the strip material, leading to measurement errors.

When the fixed end locking sleeve 304 slides along the inner slide rail 101, the first locking block 302 and the second locking block 303 approach or move away from each other.

[0056] In this embodiment, it also includes: a force screw 305, a fixed end locking sleeve 304 is provided with a screw hole 3043 from top to bottom, the screw hole 3043 is a long hole arranged along the length direction of the first inner cavity, and the bottom of the force screw 305 extends into the screw hole 3043; a toothed pressure block 307, the force screw 305 is threadedly connected to the nut block 306, the nut block 306 is fixedly connected to the first locking block 302, and the toothed pressure block 307 is fixedly provided at the bottom of the force screw 305.

[0058] In this embodiment, it also includes: an oil cylinder 6, the output end of the oil cylinder 6 is fixedly connected to the connecting plate 7, and the connecting plate 7 is fixedly connected to the movable end locking sleeve 404. The oil cylinder 6 can push the movable end locking sleeve 404, the third locking block 402 and the fourth locking block 403 in the direction away from the fixed clamping mechanism 3. In order to prevent the movable clamping mechanism 4 from eccentrically swinging, the bottom end of the connecting plate 7 slides in a preset positioning slide, and the positioning slide is set along the length direction of the bracket 1. In this embodiment, a tension sensor 9 is provided at the connection between the oil cylinder 6 and the connecting plate 7. During the thickness measurement process, the strip is tightened by the oil cylinder 6 and monitored by the tension sensor 9.

The positioning locking sleeve 501 is longitudinally slidably arranged on the locking plate 502. When the first locator 8 corresponds to the second locator, the positioning locking sleeve 501 corresponds to the movable end connecting shaft 401; a cylinder 503, which is fixedly arranged on the locking plate 502, and its output end is fixedly connected to the positioning locking sleeve 501. The cylinder 503 can drive the positioning locking sleeve 501 to move toward the upper end / lower end of the movable end connecting shaft 401, and sleeve the positioning locking sleeve 501 on the outer surface of the movable end connecting shaft 401. In this embodiment, the movable clamping mechanism 4 is provided with the same structure as the fixed clamping mechanism 3 , such as the force screw 305 .

[0061] It should be noted that when the positioning locking sleeve 501 and the movable end connecting shaft 401 are not locked, when the oil cylinder 6 drives the movable end locking sleeve 404 to move along the inner slide rail 101, the friction between the movable end locking sleeve 404 and the third locking block 402 and the fourth locking block 403 is sufficient, allowing the third locking block 402, the fourth locking block 403 and the movable end locking sleeve 404 to move synchronously, and there is no problem of falling off. In this embodiment, all structures are centrally controlled by the control center, and the transmission and feedback of various electrical signals all pass through the control center.

[0062] The specific working process is as follows:

[0063] Specifications of the materials tested: width 200mm, thickness 0.2mm~3.0mm, length 700mm~1600mm.

[0064] When the second positioning member 402 on the third locking block 402 corresponds to the first positioning member 8 on the locking plate 502, a signal is sent to the control center, which immediately stops the cylinder 6 and starts the cylinder 503 at the same time, pushing the positioning locking sleeve 501 toward the movable end connecting shaft 401 from the upper and lower directions until the movable end connecting shaft 401 enters the interior of the upper and lower positioning locking sleeves 501 to complete the positioning.

[0065] Place one end of the strip between the third locking block 402 and the fourth locking block 403, move the movable end locking sleeve 404 to press the third locking block 402 and the fourth locking block 403 inward, and finally press the toothed pressing block 307 downward by the force screw 305 to press the third locking block 402.

[0066] Similarly, place the other end of the strip between the first locking block 302 and the second locking block 303, move the fixed end locking sleeve 304 to press the first locking block 302 and the second locking block 303 inward, and finally press the first locking block 302 by pressing the toothed pressing block 307 downward through the force screw 305.

[0067] Start the drive motor 202, which drives the ball screw 201 to rotate. The thickness measuring mechanism 2 moves along the outer slide rail 102. The upper thickness sensor assembly 206 and the lower thickness sensor assembly 207 jointly detect the thickness of the strip from the upper and lower positions of the strip. The detection position is from close to the fixed clamping mechanism 3 to the movable clamping mechanism 4. When the measuring sensor 208 on the thickness measuring mechanism 2 corresponds to the feedback module on the movable clamping mechanism 4, the feedback module sends a signal to the control center. The control center controls the drive motor 202 to flip, and the thickness measuring mechanism 2 moves from the movable clamping mechanism 4 to the fixed clamping mechanism 3 to detect the thickness of the strip again.

[0068] When the strip steel inspection is completed, first remove the force screw 305 at the fixed clamping mechanism 3, move the fixed end locking sleeve 304, and separate the strip steel from the first clamping block and the second clamping block; then remove the force screw 305 at the movable clamping mechanism 4, move the movable end locking sleeve 404, separate the strip steel from the third clamping block and the fourth clamping block, and take out the strip steel.
