Description

Technical Field

[0001] This utility model relates to a testing device, and more particularly to a steel plate straightness testing device. Background Technology

[0002] Steel plates are flat steel products made by pouring molten steel, cooling and pressing them. The flatness of the steel plate during the production process is an important indicator that affects and evaluates the shape of the steel plate. Measuring the key indicators that characterize the shape of the plate is beneficial to controlling the shape quality of the steel plate.

[0003] The patent, authorized by announcement number CN213179842U, discloses an integrated steel structure testing device, including a base, limiting plates, mounting seats, connecting seats, and push plates. The base has mounting seats fixedly connected to its top. Two mounting seats are arranged parallel to each other, with an installation channel between them. Limiting plates are located within the installation channel, and two limiting plates are arranged parallel to each other, with a steel plate between them. The limiting plates are connected to the mounting seats via push rods. The patent proposes placing the steel plate on the connecting seat and then using a motor to drive a first threaded rod and push plate to move the steel plate between the two limiting plates. The straightness of the steel plate is determined by whether it gets stuck between the limiting plates. However, this patent still has some problems in practical use. When using this patent to test steel plates, relying solely on the passage of the steel plate between the two limiting plates cannot visually display the degree of flatness of the steel plate, nor can it accurately obtain the flatness data of the steel plate.

[0004] Therefore, it is necessary to design a steel plate straightness detection device that can accurately detect the flatness. Utility Model Content

[0005] In order to overcome the shortcomings of the existing patents that rely solely on the passage of the steel plate between two limiting plates when inspecting steel plates, which cannot intuitively display the degree of flatness of the steel plate or accurately obtain the flatness data of the steel plate, this utility model provides a steel plate flatness detection device that can accurately detect the flatness.

[0006] The technical solution of this utility model is: a steel plate straightness testing device, including a base frame and a support platform. The support platform is installed on the top of the base frame. The device also includes a first electric slide rail, a first electric slider, a second electric slide rail, a second electric slider, a mounting base, a lead screw, a guide rod, a mounting plate, a sliding seat, a bidirectional screw, a first dial indicator, a second dial indicator, and a connecting plate. First electric slide rails are installed on both sides of the top of the support platform. A first electric slider is slidably mounted on the first electric slide rail. A second electric slide rail is installed between the two first electric sliders. A second electric slider is slidably mounted on the second electric slide rail. A mounting base is installed on the second electric slider. A lead screw is rotatably mounted on the mounting base. A guide rod is fixedly connected to the mounting base. A mounting plate, threadedly connected to the lead screw, is slidably mounted on the guide rod. A bidirectional screw is rotatably mounted on the mounting plate. Sliding seats are slidably mounted on both sides of the mounting plate. The sliding seats are threadedly connected to the bidirectional screw. A first dial indicator is mounted on the sliding seat. A second dial indicator is mounted on the first electric slider. A connecting plate is fixedly connected to the two adjacent ends of the two second dial indicators.

[0007] As a further preferred embodiment, it also includes sliding rods, guide plates, elastic elements, and friction wheels. Sliding rods are slidably installed on both sides of the top of the support platform. Guide plates are fixedly connected to the ends of the sliding rods that are close to each other. Elastic elements are connected between the guide plates and the support platform. Multiple friction wheels are rotatably installed on the guide plates.

[0008] As a further preferred embodiment, it also includes threaded sleeves, adjusting screws, and knobs. Multiple threaded sleeves are fixedly connected to the bottom of the base frame, and adjusting screws are rotatably installed inside the threaded sleeves. A knob is fixedly connected to the end of the adjusting screw away from the support platform.

[0009] As a further preferred embodiment, it also includes a first roller, which is installed on the side of the two connecting plates that are close to each other.

[0010] As a further preferred embodiment, a second roller is also included, with the second roller mounted on the end of the first dial indicator away from the slide block.

[0011] As a further preferred option, a level is also included, with a level mounted on the first electric slider.

[0012] As a further preferred option, it also includes conveyor rollers, with multiple rotating conveyor rollers on the support platform.

[0013] As a further preferred option, the guide plates are arranged in a figure-eight shape on both sides of the support platform.

[0014] When the flatness of a steel plate needs to be tested, the steel plate is placed on a support platform and kept centered horizontally. The second dial indicator's probe contacts both sides of the steel plate. Then, the lead screw is rotated, causing the mounting plate, sliding seat, and first dial indicator to slide up and down until the first dial indicator's probe contacts the top of the steel plate. The first electric slide rail is then activated, and the first electric slider moves the second electric slide rail, the first dial indicator, and the second dial indicator left and right to test the steel plate. When there are unevennesses on the upper surface of the steel plate, the dial indicator probe moves with the surface... The device generates displacement and records the vertical deviation value. If the edge of the steel plate is wavy or warped, the second dial indicator provides real-time feedback on the lateral offset, thus simultaneously and accurately detecting the straightness of the upper and lower surfaces of the steel plate. When different positions need to be inspected, the second electric slide rail is activated, and the second electric slider on the second electric slide rail moves back and forth, allowing the mounting seat to cover any position on the steel plate. Then, the bidirectional screw is rotated, causing the two sliding seats on both sides to move closer or further apart synchronously, adapting to different detection point spacing requirements. This allows the device to accurately detect various points on the steel plate.

[0015] When the steel plate is placed on the support platform, pushing the steel plate to the left causes it to slide outward against the guide plate. The guide plate then causes the sliding rod to slide outward, and the elastic element is compressed and deforms at the bottom. This results in a clamping force being applied to both sides of the steel plate through the elastic element and the guide plate, keeping the steel plate centered when it is transported to the support platform. At the same time, the friction wheel contacts the edge of the steel plate, thus preventing rigid friction between the side of the steel plate and the guide plate, which could damage the surface.

[0016] Before inspection, the height of various parts of the base frame is adjusted by turning the knob, which drives the adjusting screw to rotate. At the same time, the support platform is monitored for levelness using a level instrument to ensure that the support platform is level as a whole, thereby reducing measurement errors caused by tilting when testing the straightness of the steel plate.

[0017] The beneficial effects of this utility model are as follows: 1. During testing, the three-dimensional position and spacing of the dial indicator are adjusted by the first electric slide rail, the second electric slide rail and the bidirectional screw. Then, the vertical undulation and side wavy offset of the steel plate surface are measured simultaneously by the first and second dial indicators, so as to realize the accurate detection of the flatness of the steel plate in multiple points and all dimensions.

[0018] 2. By applying clamping force to both sides of the steel plate through elastic elements and guide plates, the steel pipe plate is kept centered when it is transported to the support platform. At the same time, the friction wheel contacts the edge of the steel plate, thereby avoiding rigid friction between the side of the steel plate and the guide plate, which would damage the surface.

Detailed Implementation

[0027] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0028] Example 1: A steel plate straightness detection device, see reference Figures 1-5As shown, the system includes a base frame 1 and a support platform 2. The support platform 2 is bolted to the top of the base frame 1. Multiple rotating conveyor rollers 26 are mounted on the support platform 2. The conveyor rollers 26 reduce the friction when the steel plate moves on the support platform 2. The system also includes a first electric slide rail 3, a first electric slider 4, a second electric slide rail 5, a second electric slider 6, a mounting base 7, a lead screw 8, a guide rod 9, a mounting plate 10, a sliding seat 11, a double-acting screw 12, a first dial indicator 13, a second dial indicator 14, and a connecting plate 15. The first electric slide rail 3 is bolted to both the left and right sides of the top of the support platform 2. A first electric slider 4 is slidably mounted on the first electric slide rail 3. A second electric slide rail 5 is bolted between two first electric sliders 4. A second electric slider 6 is slidably mounted on the second electric slide rail 5. A mounting base 7 is bolted to the second electric slider 6. The mounting base 7 has a front... A lead screw 8 is provided for side rotation. A guide rod 9 is fixedly connected to the rear side of the mounting base 7. A mounting plate 10 is slidably provided on the guide rod 9 and threadedly connected to the lead screw 8. A bidirectional screw 12 is rotatably provided on the mounting plate 10. Sliding seats 11 are slidably provided on both sides of the mounting plate 10. The sliding seats 11 are threadedly connected to the bidirectional screw 12. A first dial indicator 13 is installed on the sliding seat 11 by bolt connection. A second dial indicator 14 is installed on the first electric slider 4 by bolt connection. A connecting plate 15 is fixedly connected to the two adjacent ends of the two second dial indicators 14. A first roller 16 is installed on the adjacent side of the two connecting plates 15 by bolt connection. A second roller 24 is installed at the lower end of the first dial indicator 13 by bolt connection. The first dial indicator 13 and the first roller 16 abut against the steel plate, reducing the friction of the steel plate on the first dial indicator 13, the second dial indicator 14 and the connecting plate 15 on both sides.

[0029] When the flatness of a steel plate needs to be tested, the steel plate is placed on the support platform 2 and kept centered on the platform. The measuring end of the second dial indicator 14 is brought into contact with both sides of the steel plate. Then, the lead screw 8 is rotated, which causes the mounting plate 10, the sliding seat 11, and the first dial indicator 13 to slide up and down, bringing the measuring end of the first dial indicator 13 into contact with the top of the steel plate. Then, the first electric slide rail 3 is activated, and the first electric slider 4 moves the second electric slide rail 5, the first dial indicator 13, and the second dial indicator 14 left and right to test the steel plate. When there are unevennesses on the upper surface of the steel plate, the dial indicator probes... The needle moves with the surface undulations, recording the vertical deviation value. If the edge of the steel plate is wavy or warped, the second dial indicator 14 provides real-time feedback on the lateral offset, thus simultaneously and accurately detecting the flatness of the upper and side surfaces of the steel plate. When different positions need to be tested, the second electric slide rail 5 is activated, and the second electric slider 6 on the second electric slide rail 5 moves back and forth, so that the mounting seat 7 covers any position on the steel plate. Then, the bidirectional screw 12 is rotated, so that the two sliding seats 11 on both sides move closer or further away synchronously, adapting to different detection point spacing requirements, so that this device can accurately detect various points on the steel plate.

[0030] Example 2: Based on Example 1, refer to Figure 1 , Figure 2 and Figure 6 As shown, it also includes a sliding rod 17, a guide plate 18, an elastic element 19, and a friction wheel 20. The sliding rod 17 is slidably arranged on both the left and right sides of the top of the support platform 2. The guide plate 18 is fixedly connected to the end of the sliding rod 17 that is close to each other. The guide plate 18 is arranged in a V-shape on both sides of the support platform 2, so that the device can adapt to steel plates of different widths. The elastic element 19 is connected between the guide plate 18 and the support platform 2. A friction wheel 20 is rotatably arranged on the guide plate 18. The friction wheel 20 is made of rubber, which can prevent the friction wheel 20 from scratching the steel plate.

[0031] When the steel plate is placed on the support platform 2, pushing the steel plate to the left causes the steel plate to press the guide plate 18 and slide it outward. The guide plate 18 drives the slide rod 17 to slide outward. The elastic element 19 is compressed and undergoes lower deformation. Thus, the elastic element 19 and the guide plate 18 apply clamping force to both sides of the steel plate, keeping the steel pipe plate centered when it is transported to the support platform 2. At the same time, the friction wheel 20 contacts the edge of the steel plate, thereby avoiding rigid friction between the side of the steel plate and the guide plate 18 and thus preventing damage to the surface.

[0032] See Figure 1 , Figure 2 and Figure 7As shown, it also includes a threaded sleeve 21, an adjusting screw 22 and a knob 23. Six threaded sleeves 21 are fixedly connected to the bottom of the base frame 1. The six threaded sleeves 21 are distributed on the front and rear sides of the bottom of the base frame 1. An adjusting screw 22 is rotatably installed inside the threaded sleeve 21. A knob 23 is fixedly connected to the lower end of the adjusting screw 22 by welding. A level 25 is installed on the first electric slider 4 by bolt connection.

[0033] Before inspection, the height of the base frame 1 is adjusted by rotating the knob 23, which drives the adjusting screw 22 to rotate. At the same time, the support platform 2 is monitored for levelness by the level instrument 25 to ensure that the support platform 2 is level, thereby reducing the measurement error caused by tilting when testing the straightness of the steel plate.

[0034] The above-described embodiments are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
