Description

Technical Field

[0001] The present invention relates to the technical field of calibration devices, and in particular to an on-site calibration device and method for a portable force measuring instrument. Background Art

[0002] The calibration of traditional force measuring instruments is usually carried out in a laboratory environment, but in certain application scenarios, such as industrial production sites, outdoor testing environments, etc., a calibration device that is easy to carry and responds quickly is needed. However, the existing calibration devices have certain defects when used. For example, in the Chinese patent with the announcement number "CN 221826368U", a calibration tool for tension measuring instruments is disclosed, including a calibration tool body, a tension meter is installed on the top of the calibration tool body, and a hook for conducting tension is installed on the tension meter, and a weight is hung on the hook. A mobile rail is fixed to the inner wall of the calibration tool body, and a mobile base is movably connected to the mobile rail. A driving electric push rod is fixed to the top of the mobile base, and a conveying plate for hanging the weight is fixed to the top of the electric push rod. A hanging ring is fixed to the top of the weight, and the hanging ring is hung. On the hook, the hanging ring is equipped with a second plug-in column and a first plug-in column, and the first plug-in column and the second plug-in column can limit the hanging ring. Although the device can calibrate the tension meter, when the device is in use, since the tension meter is directly mounted on the calibration tool body, the device can only be used for tension meters of fixed specifications and cannot be adjusted according to actual conditions. Therefore, the scope of use is limited, and each time calibration is performed, since weights of different specifications need to be used for calibration, it is necessary to repeat the steps of placing and removing weights of different specifications, thereby reducing the calibration efficiency.

[0042] Through the above technical solution, when personnel need to measure the tension measuring instrument, the device is placed at the use point, the vertical moving part 2 is supported by the support part 1, and the horizontal moving part 3 is supported by the vertical moving part 2, and the two slides 51 are pulled to move the slides 51 relative to the horizontal moving part 3 until the slides 51 move to the position required by the personnel, and then the clamping plate 54 is moved to the position required by the personnel, and the tension measuring instrument to be calibrated is placed between the two clamping plates 54, and the clamping plate 54 is driven to move by the electric push rod 52 so that the two clamping plates 54 clamp the tension measuring instrument to be measured, and the weight 44 is placed in the positioning hole 43 on the placement plate 41, and the measuring head below the tension measuring instrument is connected to the hook 45 on the weight 44, and the tension measuring instrument is calibrated by connecting and measuring with different weights 44.

[0043] Specifically, in one embodiment, regarding the horizontal moving member 3, as Figure 1-Figure 4 , Figure 8 , Fig.12 As shown, the horizontal moving member 3 includes a moving plate 31, on which a through hole 33 is provided perpendicular to the horizontal plane, and two second guide grooves 32 are symmetrically provided on the top of the moving plate 31, the through hole 33 is located between the two second guide grooves 32, and the two slide plates 51 are respectively slidably connected to the inside of the two second guide grooves 32.

[0044] In this embodiment, when the position of the slide plate 51 needs to be adjusted, the two slide plates 51 are pulled and cooperated with the second guide groove 32 on the movable plate 31 so that the slide plate 51 slides along the movable plate 31, thereby adjusting the position of the slide plate 51 and the clamp plate 54 until the slide plate 51 and the clamp plate 54 move to the position required by the personnel.

[0047] In addition, when the clamping plate 54 clamps the tension measuring instrument, in order to make the device more secure when fixing the tension measuring instrument, as shown in FIG. Fig.12 As shown, the two clamping plates 54 are bonded with convex plates 53 on opposite sides, and the surfaces of the convex plates 53 are formed with convexities.

A movable side plate 23 is screwed and connected between the two screw rods 22 , and a moving plate 31 is fixedly connected between the two side plates 23 .

[0049] In this embodiment, since the lengths of the tension measuring instruments are different, adjustments are required when testing tension measuring instruments of different specifications.
