Description

Technical Field

[0001] This utility model relates to the field of plate measurement technology, specifically to an online continuous thickness measurement device for cast and rolled plates. Background Technology

[0002] Currently, online thickness measurement of cast-rolled plates is done manually. This not only introduces certain errors but also fails to guarantee the timeliness of the measurement, easily leading to online thickness variations exceeding the specified values.

[0003] In the prior art, a continuous steel plate thickness measuring device according to Chinese patent application number 201920376940.9 includes a base, a steel plate fixing device, and a steel plate thickness measuring device. The steel plate fixing device has a first fixing plate fixedly mounted on one side of the base, with a first steel plate fixing pad positioned near the top. A second fixing plate is correspondingly mounted to the first fixing plate, with a corresponding second steel plate fixing pad. The second fixing plate is slidably connected to the base. The steel plate thickness measuring device includes a support column and a thickness gauge. One end of the support column is slidably connected to the base, and the thickness gauge is positioned at the other end of the support column. The sliding direction of the support column on the base is parallel to the sliding direction of the second fixing plate on the base. When measuring the steel plate thickness, the steel plate to be measured is fixed between the first and second fixing plates by sliding the second fixing plate. Then, sliding the support column moves the thickness gauge to different positions in the width direction of the steel plate, thereby accurately measuring the thickness at different width positions of the same cross-section of the steel plate. However, in use, it can only measure the edge thickness variation of the steel plate and cannot accurately measure the overall thickness of the plate, affecting the accuracy of the plate measurement.

[0025] According to an embodiment of the present invention, a continuous thickness measurement device for online cast and rolled sheet metal is provided.

[0026] Example 1

[0027] like Figure 1As shown in Figure 4, the online continuous thickness measurement device for cast and rolled plates according to an embodiment of this utility model includes a fixed support 1, a conveying roller 2 on the fixed support 1, a guide mechanism 3 on one side of the top of the fixed support 1, a positioning frame 4 in the middle of the fixed support 1, two sets of adjustment mechanisms 5 on the positioning frame 4, a guide rail 6 fixedly connected between the positioning frames 4, a fixed laser sensor 7 and an adjustable laser sensor 8 respectively mounted on the guide rail 6, and the adjustment mechanism 5 connected to the adjustable laser sensor 8. Water-cooling pipes 9 are provided on both sides of the device 7 and the adjustable laser sensor 8. The water-cooling pipes 9 are attached to the laser sensor to cool it down. The guide mechanism 3 includes a mounting plate 10, a hydraulic cylinder 11 and a top plate 12. The mounting plate 10 is symmetrically arranged on both sides of the fixed bracket 1. The hydraulic cylinder 11 is connected to one side of the mounting plate 10. The output end of the hydraulic cylinder 11 is connected to the top plate 12. The top plate 12 is moved by the hydraulic cylinder 11 to straighten the plate, so that the laser sensor can easily measure the thickness of the plate when it passes the positioning frame 4.

[0028] Example 2

[0029] like Figure 1-4As shown, the online continuous thickness measurement device for cast and rolled plates according to an embodiment of this utility model includes a fixed support 1, a conveying roller 2 mounted on the fixed support 1, a guide mechanism 3 mounted on one side of the top of the fixed support 1, a positioning frame 4 mounted in the middle of the fixed support 1, two sets of adjusting mechanisms 5 mounted on the positioning frame 4, a guide rail 6 fixedly connected between the positioning frames 4, a fixed laser sensor 7 and an adjustable laser sensor 8 respectively mounted on the guide rail 6, and the adjusting mechanisms 5 connected to the adjustable laser sensor 8. Water-cooling pipes 9 are provided on both sides of the optical sensor 8. The water-cooling pipes 9 are attached to the laser sensor to cool it down. The adjustment mechanism 5 includes a first lead screw 13, a second lead screw 14, a servo motor 15, a moving block 16, a sliding frame 17, a drive wheel 18, a belt 19, and a driven wheel 20. The first lead screw 13 and the second lead screw 14 are symmetrically arranged on the positioning frame 4, with the first lead screw 13 positioned above the second lead screw 14. The first lead screw 13 and the second lead screw 14 are symmetrically provided with two sections of threads with opposite directions. One end of the first lead screw 13 is connected to the servo motor 15. The output shaft of motor 15 is connected, the other end of the first lead screw 13 is connected to the drive wheel 18, one end of the second lead screw 14 is connected to the driven wheel 20, and the other end of the second lead screw 14 is rotatably connected to the positioning frame 4. The drive wheel 18 is connected to the driven wheel 20 via a belt 19. The moving blocks 16 are symmetrically arranged on the first lead screw 13 and the second lead screw 14, one end of the moving block 16 is fixedly connected to the sliding frame 17, one end of the sliding frame 17 is connected to the adjustable laser sensor 8, and the fixed laser sensor 8 is fixed on the guide rail 6. The laser sensor 8 is slidably connected to the guide rail 6 via the sliding frame 17. When measuring plates of different widths, the servo motor 15 drives the first lead screw 13 to rotate, which in turn drives the drive wheel 18, belt 19, and driven wheel 20 to rotate the second lead screw 14. This causes the moving blocks 16 on the first lead screw 13 and the second lead screw 14 to move respectively, which in turn causes the upper and lower adjustable laser sensors 8 to move synchronously. The distance between the adjustable laser sensor 8 and the fixed laser sensor 7 is adjusted to accommodate the measurement of plates of different widths.

[0030] Example 3

[0031] like Figure 1As shown in Figure 4, the online continuous thickness measurement device for cast and rolled plates according to an embodiment of this utility model includes a fixed support 1, a conveying roller 2 on the fixed support 1, a guide mechanism 3 on one side of the top of the fixed support 1, a positioning frame 4 in the middle of the fixed support 1, two sets of adjustment mechanisms 5 on the positioning frame 4, a guide rail 6 fixedly connected between the positioning frames 4, a fixed laser sensor 7 and an adjustable laser sensor 8 respectively mounted on the guide rail 6, the adjustment mechanism 5 being connected to the adjustable laser sensor 8, and the fixed laser sensor 7 and the adjustable laser sensor 8 being connected to the guide rail 6. Water-cooling pipes 9 are provided on both sides of the sensor 8. The water-cooling pipes 9 are attached to the laser sensor to cool it down. When measuring the board material, the lower laser displacement sensor and the upper laser displacement sensor are arranged opposite each other with a fixed distance. When working, the lower laser displacement sensor emits a laser beam to irradiate the lower surface of the object being measured, and the actual distance from the laser displacement sensor to the lower surface of the object being measured can be obtained. Similarly, the distance from the upper laser displacement sensor to the upper surface of the object being measured can be obtained. The thickness of the object being measured can be obtained by subtracting the distance from the two sensors to the upper and lower surfaces of the object being measured from the distance between the two sensors.

[0032] In summary, with the help of the above-mentioned technical solution of this utility model, when this device is in use, the plate is conveyed by the conveying roller 2 on the fixed bracket 1, and during the conveying, the top plate 12 is moved by the hydraulic cylinder 11 to straighten the plate, so that the plate can be easily measured by the laser sensor when it passes the positioning frame 4. When measuring the plate, the lower laser displacement sensor and the upper laser displacement sensor are arranged opposite each other at a fixed distance. When working, the lower laser displacement sensor emits a laser beam to irradiate the lower surface of the object being measured, and the actual distance from the laser displacement sensor to the lower surface of the object being measured can be obtained; similarly, the distance from the upper laser displacement sensor to the upper surface of the object being measured can be obtained. The thickness of the object can be obtained by subtracting the distance from the two sensors to the upper and lower surfaces of the object from the distance between the two sensors. This method is convenient to operate. When measuring plates of different widths, the servo motor 15 drives the first lead screw 13 to rotate, which in turn drives the drive wheel 18, belt 19, and driven wheel 20 to rotate the second lead screw 14. This causes the moving blocks 16 on the first lead screw 13 and the second lead screw 14 to move respectively, which in turn causes the upper and lower adjustable laser sensors 8 to move synchronously. The distance between the adjustable laser sensor 8 and the fixed laser sensor 7 is adjusted to adapt to measuring plates of different widths, thus improving the applicability of the device.
