[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] See also Figure 1-2 , an embodiment provided by the utility model:
[0021] A calibration device for a roller-rolled laser thickness gauge includes a scanning device and a calibration device. The scanning device includes a fixed frame 1, two groups of fixed seats 2 are installed on both sides of the fixed frame 1, and rollers 3 are arranged between each group of fixed seats 2. A marble C-shaped frame 4 is arranged on the fixed frame 1 between the two groups of rollers 3, and a laser probe assembly 5 is arranged at the front end of the marble C-shaped frame 4. A calibration device passing through the C-shaped frame 4 is provided between the rollers 3. The calibration device includes a feeler gauge fixing plate 6, an adjustment plate 7 and a pipe clamp 8. Adjustment plates 7 are provided at both ends of the feeler gauge fixing plate 6, and pipe clamps 8 connected to the rollers 3 are respectively provided on both sides of the adjustment plate 7. A feeler gauge 9 is movably fixed on the feeler gauge fixing plate 6, and the feeler gauge 9 is fixed by screws 12. The adjustment plate 7 is provided with a waist hole 10 for adjustment.
[0022] The calibration device is installed and fixed on the roller 3 of the scanning device. During this process, the feeler gauge 9 is fixed on the feeler gauge fixing plate 6 by screws 12, and the waist hole 10 of the adjustment plate 7 is used to adjust the position of the feeler gauge fixing plate 6 so that the laser probe assembly 5 can scan the entire feeler gauge 9. The longer the feeler gauge 9 is, the longer the laser measurement stroke is, the more data is collected, and the more accurate it is. After the position of the feeler gauge fixing plate 6 is adjusted, the entire calibration device is fixed on the roller 3 with the pipe clamp 8. Later, different specifications of feeler gauges 9 can be replaced as needed for calibration.
[0023] The laser probe assembly 5 includes an upper laser probe 51 and a lower laser probe 52. The bottom of the C-frame 4 is movably connected to the fixed frame 1 through a marble base 11. After the calibration device is installed and fixed, the laser probe assembly 5 of the roller laser thickness gauge is started, so that the upper laser probe 51 and the lower laser probe 52 scan the entire feeler gauge 9. The probe measurement value is compared with the actual value and calibrated, where the measurement value h = the upper and lower probe spacing H (known) - the spacing A from the upper laser probe 51 to the feeler gauge 9 - the spacing B from the lower laser probe 52 to the feeler gauge 9.
[0024] Since the bottom of the marble C-shaped frame 4 is movably connected to the fixed frame 1 via the marble base 11, and this movable connection is achieved by a movable axis, the C-shaped frame 4 can move back and forth on the fixed frame 1 following the marble base 11, driving the laser probe assembly 5 to move back and forth, thereby scanning the entire feeler gauge 9. In addition, the C-shaped frame 4 and the base 11 are both made of marble, which can increase the weight of the C-shaped frame 4 and the base 11 and increase the stability of the roller laser thickness gauge.
