AI Technical Summary
Existing stainless steel plate inspection devices cannot detect abnormalities when the two sides of a stainless steel plate are of uniform height but the middle is concave, resulting in large errors in the inspection results. Furthermore, the efficiency of inspecting stainless steel plates by flipping them over is low, and the position is prone to shift, affecting the inspection effect.
The stainless steel plate is fixed by a fixed structure including a base plate, support rod, L-shaped fixing plate, electric push rod and clamping plate. The reciprocating sliding assembly and drive assembly drive the distance sensor to detect both sides synchronously. The reciprocating motion of the detection assembly is realized by servo motor, ball screw pair and limit rod. Automatic detection and alarm are realized by distance sensor and controller alarm.
This technology enables simultaneous inspection of both sides of stainless steel plates, improving inspection efficiency, reducing positional offset, enhancing inspection accuracy and range, and ensuring the accuracy of inspection results.

A flatness testing device for stainless steel plate production Technical Field
[0001] This application relates to the field of stainless steel plate testing, and more specifically, to a flatness testing device for stainless steel plate production. Background Technology
[0002] Stainless steel sheet is an alloy steel that does not easily rust. During the rolling process, inconsistencies in the internal chemical composition of the sheet can lead to uneven stress on the surface under the pressure of the rolling mill, resulting in surface flatness defects. To control the quality of the finished steel sheet, it is necessary to inspect its flatness. Currently, the equipment used for inspecting the flatness of steel sheets...
[0003] While current stainless steel plate testing devices can detect the flatness of stainless steel plates to some extent based on whether the laser can be received normally, the laser emitter and receiver are located on the two sides of the stainless steel plate. Unevenness can only be detected when the center of the stainless steel plate protrudes from both sides. When the height of the two sides of the stainless steel plate is consistent but the center is concave, the abnormality cannot be detected and it will still be judged as qualified. This results in a large error in the test results of the entire equipment.
[0004] Chinese patent application CN202222675496.5 discloses a device for detecting the surface flatness of stainless steel sheets, including a testing platform and a testing rod suspended above the testing platform. A hanging rod is fixed at the middle position of the upper surface of the testing rod. The device determines whether the surface of the stainless steel sheet is flat by comparing the detection distance values of multiple distance sensors on the same longitudinal line of the stainless steel sheet surface. This effectively avoids the problem of limited detection range when using a pair of laser beam sensors for detection in traditional technology, and helps to improve the accuracy of the detection effect.
[0005] The above solution has the following shortcomings: When using it, the stainless steel plate to be tested is placed on the testing table and the surface is tested. However, after one side of the stainless steel plate is tested, it needs to be flipped over to test the other side. It is not easy to test both sides at the same time, which reduces work efficiency. At the same time, the position of the stainless steel plate is not easy to fix and it is easy to shift during testing, which affects the testing effect. Summary of the Invention
[0006] To overcome the above shortcomings, this application provides a flatness testing device for stainless steel plate production. It aims to improve the problem that after the stainless steel plate is tested on one side, it needs to be flipped over to test the other side, which makes it difficult to test both sides simultaneously, thus reducing work efficiency. At the same time, the position of the stainless steel plate is not easy to fix, and it is easy to shift during the test, thus affecting the test results.
[0007] This application provides a flatness testing device for stainless steel plate production, including a fixing structure and a testing structure. The fixing structure includes a base plate, support rods, two L-shaped fixing plates, an electric push rod, and a clamping plate. The support rods are fixedly connected to the four corners of the base plate. The two L-shaped fixing plates are fixedly connected to the support rods. The electric push rods are installed on one side of each of the two L-shaped fixing plates. The clamping plate is fixedly connected to the movable end of the electric push rod. The testing structure includes a reciprocating sliding assembly, two mounting frames, and a testing component. The reciprocating sliding assembly is fixedly connected to the support rods. The two mounting frames are connected to the reciprocating sliding assembly. The testing component is slidably connected within each of the two mounting frames.

[0011] In the above implementation process, the flatness of the stainless steel plate is conveniently detected by setting up a sliding plate, a moving rod and a distance sensor body. The distance sensor body can be, but is not limited to, laser distance sensors, ultrasonic distance sensors, etc.
[0012] In one specific implementation, a drive assembly is provided on one side of the mounting frame.

[0013] In the above implementation process, the arrangement of gears, toothed plates, rotating shafts, rotating plates, first connecting shafts, connecting rods, second connecting shafts, and rotating blocks can easily drive multiple ranging sensor bodies to reciprocate, thereby improving the detection range.
[0014] In one specific implementation, a controller body and an alarm body are respectively installed on one side of the mounting frame, and both the ranging sensor body and the alarm body are electrically connected to the controller body.
[0015] In the above implementation process, the controller body can adopt a single-chip microcomputer commonly used in the prior art, while the alarm body can adopt a buzzer alarm or audible and visual alarm commonly used in the prior art. The detection data is transmitted to the controller body through the distance sensor body. When the distance values are consistent, it indicates that the stainless steel plate surface is flat. When the distance values are different, it indicates that the stainless steel plate surface is not flat. At this time, the controller body controls the alarm body to work and sound an alarm to indicate that the plate surface is not flat.
[0016] In one specific implementation, two first sliding rods are fixedly connected to one side of the support rod, and the two mounting frames are slidably connected to the two first sliding rods respectively.

[0030] Please refer to Figure 1. This application provides a flatness testing device for stainless steel plate production, including a fixing structure 10 and a testing structure 20.
[0031] Please refer to Figures 1, 2 and 4. The fixed structure 10 includes a base plate 110, a support rod 120, two L-shaped fixing plates 130, an electric push rod 140 and a clamping plate 150.

[0032] In a specific configuration, two first slide rods 160 are fixedly connected to one side of the support rod 120, and two mounting frames 220 are slidably connected to the two first slide rods 160 respectively.

Through the configuration of the connecting frame 211, servo motor 212, ball screw pair 213, screw nut pair 214, and limiting rod 215, the two sets of detection components 230 can be easily driven to reciprocate.
[0036] In a specific configuration, the detection component 230 includes a sliding plate 231, a moving rod 232, and a ranging sensor body 233. The moving rod 232 is fixedly connected to both sides of the sliding plate 231, and the moving rod 232 is slidably connected to the mounting frame 220. Several ranging sensor bodies 233 are evenly installed on one side of the sliding plate 231. The arrangement of the sliding plate 231, the moving rod 232, and the ranging sensor body 233 facilitates the detection of the flatness of the stainless steel plate. The ranging sensor body 233 can be, but is not limited to, laser ranging sensors, ultrasonic ranging sensors, etc.
[0037] In a specific configuration, a drive assembly 240 is provided on one side of the mounting frame 220. The drive assembly 240 includes a gear 241, a gear plate 242, a rotating shaft 243, a rotating plate 244, a first connecting shaft 245, a connecting rod 246, a second connecting shaft 247, and a rotating block 248. The gear plate 242 is fixedly connected to the support rod 120, the gear 241 is fixedly connected to the outer ring of the rotating shaft 243, and the gear 241 meshes with the gear plate 242. The rotating shaft 243 is rotatably connected to the mounting frame 220, and the rotating plate 244 is fixedly connected to one end of the rotating shaft 243.

[0038] In the specific setup, a controller body 250 and an alarm body 260 are respectively installed on one side of the mounting frame 220. The distance sensor body 233 and the alarm body 260 are both electrically connected to the controller body 250. The controller body 250 can be a single-chip microcomputer, which is common in the prior art, while the alarm body 260 can be a buzzer alarm or a sound and light alarm, which is commonly used in the prior art. The distance sensor body 233 detects and transmits the detection data to the controller body 250. When the distance values are consistent, it indicates that the surface of the stainless steel plate is flat. When there are differences in the distance values, it indicates that the surface of the stainless steel plate is uneven. At this time, the controller body 250 controls the alarm body 260 to work and sound an alarm to indicate that the plate surface is uneven.
[0039] The working principle of the flatness testing device for stainless steel plate production is as follows: When using the device, the stainless steel plate is placed on two L-shaped fixed plates 130. Two electric push rods 140 are activated to synchronously push the clamping plate 150 to clamp the plate. During testing, the servo motor 212 drives the ball screw pair 213 to rotate, causing the screw nut pair 214 to reciprocate along the limit rod 215. This synchronously drives the two mounting frames 220 to move laterally along the first sliding rod 160, facilitating simultaneous testing of both sides of the plate. During this movement, the toothed plate 242 fixed to the support rod 120 meshes with the gear 241, driving the rotation... Shaft 243 drives the rotating plate 244 to rotate, and through the linkage of the first connecting shaft 245, the connecting rod 246 and the second connecting shaft 247, pushes the rotating block 248 and the sliding plate 231 to slide within the mounting frame 220 via the moving rod 232, realizing the reciprocating longitudinal movement of multiple distance sensor bodies 233, thereby improving the detection range. The detection data of the distance sensor bodies 233 are transmitted to the controller body 250. When the distance values are all consistent, it indicates that the surface of the stainless steel plate is flat. When there are differences in the distance values, it indicates that the surface of the stainless steel plate is uneven. At this time, the controller body 250 controls the alarm body 260 to work and alarm, indicating that the plate surface is uneven.
[0040] It should be noted that the specific models and specifications of the electric push rod 140, servo motor 212, distance sensor body 233, controller body 250 and alarm body 260 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
[0041] The power supply and operating principles of the electric actuator 140, servo motor 212, distance sensor body 233, controller body 250, and alarm body 260 are clear to those skilled in the art and will not be described in detail here.
[0042] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
