[0002] In the fields of industrial production, scientific research experiments and quality inspection, the accuracy of measuring instruments is of vital importance. Flatness is one of the important indicators to measure the accuracy of measuring instruments. Its accuracy directly affects the reliability of measurement results. However, due to errors in the manufacturing process, changes in the use environment and wear caused by long-term use, the flatness of the measuring rod of the measuring instrument often deviates, which in turn affects its measurement accuracy. Therefore, it is necessary to regularly adjust the flatness of the measuring rod of the measuring instrument.

[0003] However, the existing devices have certain defects when used. For example, in a Chinese patent with the announcement number "CN 204854674U", a correction device for the verticality and flatness of a cylindrical measuring instrument is disclosed. Although the device can adjust the flatness of the measuring rod of the measuring instrument, it requires personnel to manually grind the measuring rod of the measuring instrument, which increases the difficulty of adjusting the flatness of the measuring instrument and reduces the efficiency of adjusting the flatness of the measuring instrument. In addition, when the device grinds the flatness of the measuring instrument, the debris generated by the grinding will affect the normal grinding of the measuring rod of the measuring instrument, further increasing the difficulty of adjusting the flatness of the measuring instrument and reducing the efficiency of adjusting the flatness of the measuring instrument. Utility Model Content

[0023] A motor 5 is mounted on the supporting member, and an output end of the motor 5 is connected to a screw rod 19 .

[0024] In this embodiment, when personnel need to adjust the flatness of the measuring rod of the measuring instrument, the end of the measuring rod whose flatness needs to be adjusted is vertically inserted into the fixed cavity on the clamp member. After the measuring rod is fixed in the fixed cavity of the clamp member, the motor 5 drives the screw 19 to rotate on the support member, and then the moving member moves along the length direction of the screw 19. When the moving member moves, the clamp member is driven to move by the moving member, and then the clamp member drives the measuring rod to move relative to the support member, so that the measuring rod and the support member rub against each other, and then the flatness of the measuring rod is adjusted. When the flatness of the measuring rod is adjusted, the measuring rod after the flatness adjustment is removed, thereby completing the flatness adjustment of the measuring instrument.

[0025] In addition, in the present invention, when the measuring rod of the measuring instrument is polished, in order to clean the debris generated during the polishing, such as Figure 1-Figure 2 As shown, two flow guides for conveying gas along a preset path are symmetrically arranged on the support member, and the clamp member is located between the gas outlet ends of the two flow guides.

[0026] In this embodiment, when the measuring rod is adjusting the flatness, the guide member works to transport gas along a preset path, thereby blowing the gas toward the debris generated when adjusting the flatness, thereby avoiding excessive friction between the debris and the measuring rod. When the flatness of the measuring rod is adjusted, the measuring rod with adjusted flatness is removed, thereby completing the flatness adjustment of the measuring instrument.

[0027] Specifically, in one embodiment, regarding the above-mentioned clamp member:

[0029] In this embodiment, the end of the measuring rod that needs to adjust the flatness is inserted into the through hole 7 on the positioning tube 6 so that the measuring rod is inserted vertically. The positioning screw 8 on the positioning tube 6 is rotated by the rotating head 9 to move the positioning screw 8 relative to the positioning tube 6 until the positioning screw 8 hits the measuring rod in the through hole 7. After the measuring rod is fixed in the through hole 7 of the positioning tube 6, the motor 5 is operated, and then the motor 5 drives the screw 19 to rotate on the supporting member, and then the moving member moves along the length direction of the screw 19. When the moving member moves, the clamp member is driven to move by the moving member, and then the clamp member drives the measuring rod to move relative to the supporting member, so that the measuring rod rubs against the support member, and then the flatness of the measuring rod is adjusted. After the flatness of the measuring rod is adjusted, the measuring rod after the flatness adjustment is removed, thereby completing the flatness adjustment of the measuring instrument, and there is no need for personnel to manually adjust the flatness of the measuring rod of the measuring instrument.

After the measuring rod is fixed in the through hole 7 of the positioning tube 6, the motor 5 is operated to drive the screw 19 to rotate on the base 1, so that the moving component moves along the length direction of the screw 19. When the moving component moves, the positioning tube 6 is driven to move by the moving component, and the positioning tube 6 drives the measuring rod to move relative to the base 1, so that the measuring rod rubs against the base 1, and then the flatness of the measuring rod is adjusted. After the flatness of the measuring rod is adjusted, the measuring rod after the flatness adjustment is removed, thereby completing the flatness adjustment of the measuring instrument.

[0033] Specifically, in one embodiment, regarding the above-mentioned moving member:
