Description

Technical Field

[0001] The utility model relates to the technical field of detection and calibration equipment, in particular to a metering instrument detection and calibration equipment which is convenient for fixing metering instruments. Background Technique

[0002] Common metering instruments include tension gauges, flow meters, pressure sensors, temperature sensors, etc., which are widely used in all aspects of production and life. The accuracy of metering instruments is very important to ensure the normal operation of production and life. The tension gauge is a small and simple thrust. The handheld tension gauge has the advantages of high precision, easy operation and convenient carrying, and has a peak switching operation knob, which can be used for load peak indication and continuous load value indication. At present, after the handheld tension gauge is used for a period of time, the metering error will increase. When the tension gauge needs to be calibrated after long-term use, the common calibration equipment on the market generally stretches the tension gauge and calibrates it by observing the pressure gauge and the tension display of the gauge. However, in this process, the calibration equipment needs to fix the gauge. Generally, the calibration equipment directly uses a hook to fix both ends of the gauge. Since the hook is semi-open, there is not only a risk of the gauge slipping, but also the calibration result will be affected, so it needs to be improved. Content of the Utility Model

[0003] The purpose of the utility model is to solve the technical problems put forward in the above background technique.

[0004] The utility model adopts the following technical scheme: a metering instrument detection and calibration equipment which is convenient for fixing metering instruments, including a base, a bracket is fixedly installed on the surface of the base, a motor is fixedly installed on the surface of the bracket, a lead screw is fixedly installed at the output end of the motor, a moving plate is slidably connected to the surface of the lead screw, fixing blocks are fixedly installed on the surfaces of the moving plate and the bracket, a rotating block is fixedly installed on the surface of the fixing block, a clamping ring is fixedly installed on the surface of the rotating block, a pressure tester is fixedly installed on the surface of the bracket, a pressure plate is fixedly installed on the surface of the pressure tester, a fixing plate is fixedly installed on the surface of the pressure plate, and a spring is fixedly installed on the surface of the fixing plate.

[0005] Preferably, the spring is fixedly connected to the moving plate. Here, during the pressure test, the gauge is stretched by moving the moving plate, and at the same time, the spring is compressed, so that the pressure tester can read the tension value of the gauge.

[0006] Preferably, a top plate is fixedly installed at the bottom end of the bracket, and the moving plate is slidably connected to the top plate. Here, the top plate and the moving plate are slidably connected, which can limit the moving plate and effectively prevent the moving plate from shifting and affecting the calibration effect.

[0007] Preferably, the lead screw is located inside the base. Here, the lead screw inside the base can be protected, improving the service life of the lead screw.

[0008] Preferably, the number of the springs is four groups, and the four groups of springs are symmetrically distributed on the surface of the pressure plate. Here, the four groups of springs can increase the stress area between the moving plate and the pressure plate, improving the accuracy of the lateral pressure.

[0009] Preferably, a screw hole is formed on the surface of the fixed block, a round hole is formed on the surface of the snap ring, and a bolt is threadedly connected between the round hole and the screw hole. Here, when rotating the snap ring to fix the tension gauge, screw in the bolt so that the snap ring is completely fixed to the fixed plate, further improving the stability when the tension gauge is fixed.

[0010] Preferably, a pull ring is rotatably connected to the surface of the bolt. Here, the rotatably connected pull ring can not only facilitate the rotation of the bolt by personnel, but also save a large amount of space.

[0011] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

Since the snap ring after fitting is completely closed, this can effectively prevent the gauge from slipping and affecting the calibration result.

[0013] 2. In the present utility model, by providing a screw hole, a round hole, a bolt, and a pull ring structure, when rotating the snap ring to fix the tension gauge, screw in the bolt so that the snap ring is completely fixed to the fixed plate, further improving the stability when the tension gauge is fixed.

It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1

[0023] Please refer to Figures 1-3, the present utility model provides a technical solution: a metering instrument detection and calibration device for facilitating the fixation of metering instruments, including a base 1, a bracket 2 fixedly installed on the surface of the base 1, a motor 3 fixedly installed on the surface of the bracket 2, a lead screw 4 fixedly installed at the output end of the motor 3, a moving plate 5 slidably connected to the surface of the lead screw 4, fixing blocks 7 fixedly installed on the surfaces of both the moving plate 5 and the bracket 2, a rotating block 8 fixedly installed on the surface of the fixing block 7, a clamping ring 9 fixedly installed on the surface of the rotating block 8, a pressure gauge 10 fixedly installed on the surface of the bracket 2, a pressure plate 11 fixedly installed on the surface of the pressure gauge 10, a fixing plate 12 fixedly installed on the surface of the pressure plate 11, a spring 13 fixedly installed on the surface of the fixing plate 12, and the spring 13 is fixedly connected to the moving plate 5. During the pressure test, the metering instrument is stretched by moving the moving plate 5, and at the same time, the spring 13 is compressed, so that the pressure gauge 10 can read the pulling force value of the metering instrument. A top plate 6 is fixedly installed at the bottom end of the bracket 2, and the moving plate 5 is slidably connected to the top plate 6. The sliding connection between the top plate 6 and the moving plate 5 can limit the moving plate 5 and effectively prevent the moving plate 5 from shifting, affecting the calibration effect. The lead screw 4 is located inside the base 1. The lead screw 4 inside the base 1 can protect the lead screw 4 and improve the service life of the lead screw 4. The number of springs 13 is four groups, and the four groups of springs 13 are symmetrically distributed on the surface of the pressure plate 11. The four groups of springs 13 can increase the force-bearing area between the moving plate 5 and the pressure plate 11 and improve the accuracy of the lateral pressure.

[0024] Embodiment Two

[0025] Please refer to Figure 4 , a threaded hole 14 is provided on the surface of the fixing block 7, a circular hole 15 is provided on the surface of the clamping ring 9, and a bolt 16 is threadedly connected between the circular hole 15 and the threaded hole 14. When rotating the clamping ring 9 to fix the tensile force measuring instrument, the bolt 16 is screwed in so that the clamping ring 9 is completely fixed to the fixing plate 12, thereby further improving the stability when the tensile force measuring instrument is fixed. A pull ring 17 is rotatably connected to the surface of the bolt 16. The rotatably connected pull ring 17 can not only facilitate the rotation of the bolt 16 by personnel but also save a large amount of space.

[0026] Working principle: When in use, first place the measuring instrument detection and calibration device on a flat surface. Then rotate the snap ring 9 and put the two ends of the tensile force gauge on the snap ring 9. Subsequently, rotate the snap ring 9 to make the snap ring 9 fit with the fixed plate 7. Since the snap ring 9 is completely closed after fitting, it can effectively prevent the gauge from slipping and affecting the calibration result. Then turn on the motor 3, and the motor 3 drives the lead screw 4 to rotate, thereby driving the moving plate 5 to move. When the moving plate 5 moves to the point where the tensile force gauge just shows zero scale, turn on the pressure gauge 10. Then continue to move the moving plate 5. The moving plate 5 starts to stretch the gauge and also squeezes the spring 13, so that the pressure gauge 10 can read the tensile force value of the gauge, and thus the tensile force gauge can be accurately calibrated. The top plate 6 and the moving plate 5 are slidably connected, which can limit the moving plate 5 and effectively prevent the moving plate 5 from shifting and affecting the calibration effect. When rotating the snap ring 9 to fix the tensile force gauge, screw in the bolt 16 to make the snap ring 9 and the fixed plate 12 completely fixed, thereby further improving the stability when the tensile force gauge is fixed.

[0027] The above are only the preferred embodiments of the present invention, and are not limitations to the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
