Description

Technical Field

[0001] This utility model relates to the field of pyrometer calibration technology, specifically a simple device for pyrometer calibration and adjustment. Background Technology

[0002] Non-contact pyrometers are widely used in industries such as steel and non-ferrous metals, and regular calibration is crucial to ensure measurement accuracy. The traditional calibration method involves placing the blackbody furnace on a horizontal table and manually adjusting the pyrometer angle by aiming at the image through the aiming window, ensuring the center of the pyrometer's detector lens is aligned with the center of the target surface in the blackbody furnace cavity on the same optical axis. However, blackbody furnaces have long heating and cooling times, and calibration specifications require at least six measurements at three temperature points.

[0003] The above methods are cumbersome to operate and have poor coaxial stability. They require constant adjustment of the pyrometer angle to maintain coaxiality. Some calibration stations have also purchased camera-specific tripods, which improve stability, but the tripod head tray area is relatively small and cannot directly fix the cylindrical pyrometer. Therefore, a simple device for pyrometer calibration and adjustment is proposed. Utility Model Content

A transmission bevel gear 8 is provided on the lower end of the adjusting screw 7. A rotating rod 9 is rotatably installed at the lower end of the inner tube 2. A driving bevel gear 10 is provided at the end of the rotating rod 9 near the transmission bevel gear 8. A transmission gear 11 is provided at the outer end of the rotating rod 9. A driving gear 12 is provided on the outer side of the outer tube 2 and is rotatably connected to the outer tube 2. The driving gear 12 is meshed with the transmission gear 11.

[0030] The top shell 14 is located at the upper end of the inner tube 3. A fan-shaped top block 15 is rotatably installed inside the upper end of the top shell 14. A U-shaped groove tray 16 is horizontally rotatably installed at the upper end of the fan-shaped top block 15 via a bearing. A binding strap 17 is provided at the upper end of the U-shaped groove tray 16. A second limiting bolt 19 is provided at the front end of the top shell 14, and the second limiting bolt 19 is connected to the top shell 14 by a threaded engagement. The second limiting bolt 19 penetrates and extends into the interior of the top shell 14. The bottom of the U-shaped groove tray 16 is also provided with a UNC1 / 4 universal screw for fixing a handheld infrared thermometer with a fixing screw hole.

[0031] Please see Figure 1 and Figure 2 A hand-cranked turntable 13 is provided on the outside of the drive gear 12, and the hand-cranked turntable 13 is connected to the drive gear 12. The hand-cranked turntable 13 is turned to rotate the drive gear 12.

[0032] Please see Figure 1 and Figure 2 The hand-twisting turntable 13 has anti-slip ridges on its exterior, and the anti-slip ridges are integrally formed with the hand-twisting turntable 13, which improves the anti-slip properties.

[0033] Please see Figure 1 and Figure 2 A level 18 is provided on the upper front side of the U-shaped groove tray 16, and the level 18 is connected to the U-shaped groove tray 16. The level 18 is used to facilitate observation when the U-shaped groove tray 16 needs to be leveled.

[0034] Please see Figure 3 The front end of the top shell 14 is provided with a scale 21 distributed in a ring, and the scale 21 is connected to the top shell 14.

[0035] Please see Figure 3 A pointer 20 is provided at the front end of the sector-shaped top block 15, and the pointer 20 is connected to the sector-shaped top block 15. The pointer 20 moves as the sector-shaped top block 15 rotates, and the pointer 20 is used to record the rotation angle.

[0036] This scheme: Place the blackbody furnace on a horizontal platform, then position this device directly opposite the furnace cavity opening. The horizontal distance between the inner tube 3 and the furnace cavity opening should meet the requirement of the ratio D:S of the distance D to the effective diameter S of the measured target, as specified in the pyrometer user manual. After loosening the first limit bolt 6, rotate the hand-operated turntable 13. The drive gear 12 rotates and transmits the rotation to the transmission gear 11, which in turn causes the drive bevel gear 10 to rotate and transmit the rotation to the transmission bevel gear 8. The adjusting screw 7 at the upper end of the transmission bevel gear 8 rotates. Under the threaded engagement and the sliding connection between the slider 5 and the groove 4, the rotational motion of the adjusting screw 7 is converted into the linear motion of the inner tube 3, thereby causing the inner tube 3 to rise and fall, so that the center of the U-shaped tray 16 is aligned with the furnace cavity opening. With the center basically at the same horizontal level, the first limiting bolt 6 is locked to fix the inner tube 3. The pyrometer is placed on the U-shaped groove tray 16 and fixed with the binding strap 17. The second limiting bolt 19 is loosened and the fan-shaped top block 15 is rotated to adjust its left and right angles. The pointer 20 and scale 21 are used to record the adjusted angles. At the same time, the U-shaped groove tray 16 is rotated horizontally as needed to make the axis of the pyrometer aligned with the center of the blackbody furnace cavity. Then the second limiting bolt 19 is locked. Finally, the field of view is observed through the pyrometer observation window to see if it is completely within the range of the blackbody furnace cavity. Then, by fine-tuning the height of the inner tube 3, the angle of the fan-shaped top block 15, and the rotation direction of the U-shaped groove tray 16, the calibrated pyrometer is made to be completely coaxial with the blackbody radiation source in the blackbody furnace.
