[0002] The main purpose of calibrating a balance is to ensure the accuracy and precision of its measurement results. During the use of a balance, it will be affected by various factors, such as environmental changes, aging of the scale, equipment damage, etc. These factors will cause errors in the measurement results of the balance. Therefore, regular calibration of the balance is a prerequisite for ensuring its stability, high precision and accuracy.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 7 The present invention provides the following technical solutions: a balance calibration device, comprising a calibration device body, the calibration device body comprising a calibration bracket 1, a water injection mechanism 3, a drive assembly 4 and a weighing and analyzing assembly 6, a top plate 2 is welded on the top of the calibration bracket 1, a water injection mechanism 3 is installed on the top of the top plate 2, a plug-in pipe 11 is welded on the bottom of the water injection mechanism 3, a drive assembly 4 is also screwed on the surface of the top plate 2, a transmission mechanism 5 is welded on the end of the drive assembly 4, a first rotating arm 18 and a second rotating arm 19 are integrally formed on the side of the transmission mechanism 5, and a push sleeve 20 is welded on the ends of the first rotating arm 18 and the second rotating arm 19, a counterweight 25 is embedded in the weighing and analyzing assembly 6, the number of the counterweight 25 is two, a linkage rod 40 is welded on the top of each of the counterweights 25, the top of each of the linkage rods 40 is inserted into the inside of the push sleeve 20, and the water injection mechanism 3 is embedded in the weighing and analyzing assembly 6 through the plug-in pipe 11 at the bottom. The balance calibration device is used for calibrating and testing the dynamic weighing of a balance to be calibrated.

[0029] When the present invention is used, the balance to be calibrated is first placed on a completely horizontal calibration workbench, and then the calibration device can be placed around the balance to be calibrated, placed on the workbench with the help of the calibration bracket 1, and the weighing and analyzing component 6 is placed on the surface of the balance to be calibrated. At this time, the top driving component 4 is movably connected with the two counterweights 25 in the bottom weighing and analyzing component 6 with the help of the transmission mechanism 5. After starting the driving component 4, the two counterweights 25 can be driven to rotate around the center point of the weighing and analyzing component 6 at the same time, and the calibration process of the balance to be calibrated is realized during the rotation process. On the other hand, after completing the weighing calibration of the moving object, the water injection mechanism 3 on the top is started, and clean water with a fixed flow rate is slowly added to the inside of the weighing and analyzing component 6, and the balance to be calibrated is monitored in the process to measure the object with continuous and stable weight gain, so as to achieve the purpose of dynamic calibration.

[0030] In this embodiment, the driving assembly 4 includes a motor 13 and an outer sleeve 15, the surface of the outer sleeve 15 is keyed with a gear 16, the output end of the motor 13 is sleeved with a toothed belt 14, the bottom of the outer sleeve 15 is welded with a transmission rod 17, and the transmission mechanism 5 is welded to the end of the transmission rod 17. The other end of the toothed belt 14 is sleeved on the side of the gear 16, the outer sleeve 15 passes downward from the middle position of the top plate 2, the outer shell of the motor 13 is fixed to the surface of the top plate 2 with screws, and the bottom of the calibration bracket 1 is pressed on the surface of the platform for placing the balance to be calibrated.

[0031] Specifically, in the driving component 4, after starting the motor 13 on the top, the toothed belt 14 can be driven to rotate through the output shaft on the motor 13, and the toothed belt 14 drives the gear 16 at the other end and the outer sleeve 15 in the middle of the gear 16 to rotate. Since the outer sleeve 15 is embedded in the top plate 2 through the bearing, it can directly rotate and drive the two rotating arms to rotate at the same time with the help of the transmission rod 17 at the bottom, so that the two counterweights 25 on the weighing and analysis component 6 finally complete the rotation process along with the rotation process.

[0032] In this embodiment, the transmission mechanism 5 includes a first rotating disk 32 and a second rotating disk 37, the first rotating arm 18 is integrally formed on the side of the first rotating disk 32, the second rotating arm 19 is integrally formed on the side of the second rotating disk 37, and a docking bearing 33 is embedded in the middle of the first rotating disk 32. The end of the transmission rod 17 is welded to the surface of the first rotating disk 32, and the surface of the first rotating disk 32 is interspersed with a first locking bolt 34 and a second locking bolt 35, and the side of the second rotating disk 37 is provided with a threaded hole 36, and the first rotating disk 32 is pressed on the surface of the second rotating disk 37. The counterweight 25 in the weighing and analyzing component 6 is driven by the driving component 4 and the transmission mechanism 5 to rotate horizontally on the surface of the balance to be calibrated in an active state, thereby realizing a dynamic calibration process, and the dynamic calibration process can realize two motion states of symmetrical placement and asymmetrical placement by means of the transmission mechanism 5 and the two counterweights 25 at the bottom, further expanding the analysis range of dynamic calibration.

[0033] Specifically, in the transmission mechanism 5, the two locking bolt areas on the first rotating disk 32 are respectively used to connect the threaded holes 36 at the bottom, so as to change the relative angle between the two rotating arms. In this process, the first locking bolt 34 is first connected to the threaded hole 36. At this time, the fixed state of the two is as follows: Figure 1 As shown, at this time, the two push sleeves 20 are symmetrically arranged at the two ends of the transmission mechanism 5, so that the two counterweights 25 connected at the bottom can also be evenly located on both sides of the weighing and analysis component 6, and maintain the symmetrical state to provide the movement process, and calibrate the weighing of the symmetrical moving object of the bottom balance to be calibrated. Then the second locking bolt 35 is locked and connected with the locking screw hole, and the two push sleeves can be brought close together. At this time, the two counterweights 25 at the bottom are in contact with each other. At this time, the movement process can always move an asymmetrical object on the surface of the balance to be calibrated, and monitor the measurement data of the balance to be calibrated by the continuous change of the center of gravity position during the movement process, thereby completing the calibration process.

[0034] In this embodiment, the water injection mechanism 3 includes a water tank 9 and an inner sleeve 10. A support plate 8 is welded to the surface of the top plate 2. A support plate 7 is welded to the top of the support plate 8. A water tank 9 is placed on the surface of the support plate 7. An inner sleeve 10 is plugged into the bottom of the water tank 9. A plug-in pipe 11 is integrally formed at the bottom of the inner sleeve 10. A valve 12 is installed on the surface of the plug-in pipe 11. The plug-in pipe 11 passes downward from the middle of the first rotating disk 32 and the second rotating disk 37 in sequence, and the first rotating disk 32 is movably connected to the surface of the plug-in pipe 11 through the inner docking bearing 33. The inner sleeve 10 is embedded in the interior of the outer sleeve 15. The interior of the water tank 9 is connected to the interiors of the inner sleeve 10 and the plug-in pipe 11. A water injection mechanism 3 is installed on the top of the top plate 2, through which liquid can be continuously and stably injected into the weighing and analyzing component 6 at the bottom. With the help of the water injection mechanism 3 at the top, the weighing stability of the balance with continuous weight gain can also be analyzed and calibrated, and this process will not interfere with the transmission purpose provided by the transmission mechanism 5 at the bottom. Specifically, after opening the valve 12, the water at the top can flow into the weighing and analyzing component 6 at the bottom along the inner sleeve 10 and the plug-in tube, and the entire weighing and analyzing component 6 will never be affected by the change of the force applied in the vertical direction by the top water injection mechanism 3 and the transmission mechanism 5, so the pressing effect on the balance to be calibrated also depends only on the structure of the weighing and analyzing component 6 itself.

[0035] In this embodiment, the weighing and analyzing assembly 6 includes a top plywood 21, a bottom plywood 22 and a counterweight 25. The surface of the top plywood 21 is provided with a circular track 30. The side of the top plywood 21 is welded and fixed to the side of the bottom plywood 22 through a column 29. A water storage tank 28 is provided in the middle of the top plywood 21. The surface of the water storage tank 28 is covered with a cover plate 23. A receiving sleeve 24 is inserted in the middle of the cover plate 23. A hollow sleeve 26 is welded to the bottom of the receiving sleeve 24. A sponge column 27 is embedded in the hollow sleeve 26. The end of the plug-in pipe 11 is embedded in the inside of the receiving sleeve 24, and the surface of the plug-in pipe 11 is in the inner wall of the receiving sleeve 24. The counterweight 25 includes a movable block 38 and a linkage rod 40, the linkage rod 40 is welded to the top of the movable block 38, a plurality of balls 41 are embedded at the bottom of the movable block 38, a magnetic sheet 39 is attached to one end of each movable block 38, a slide groove 31 is provided on the surface of the bottom clamp plate 22, and the balls 41 are pressed inside the slide groove 31. A sponge column 27 is embedded in the inner water storage tank 28 inside the weighing and analyzing component 6, so when water is continuously and evenly injected into the water storage tank 28 through the water injection mechanism 3 at the top, it can ensure that the liquid can be evenly and slowly infiltrated into the water storage tank 28 with the help of the sponge column 27, avoiding the chaotic shaking caused by the collision between the inflow process and the accumulated liquid, which interferes with the calibration analysis results.

[0036] Specifically, after the clean water from the top flows into the interior of the receiving sleeve 24, it first contacts the sponge column 27, and then can be evenly introduced into the interior of the water storage tank 28 through the downward penetration effect of the sponge column 27, thereby preventing the clean water from the top from directly hitting the water accumulated in the water storage tank 28 and causing a large amount of shaking, ensuring that the continuously increased weight is more stable and uniform. In addition, the counterweight 25 in this embodiment always rotates along the slide 31 through the ball 41 at the bottom, and the push sleeve 20 also only provides thrust in the horizontal direction, which will not interfere with the pressure applied to the balance to be calibrated by the entire weighing and analysis component 6.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
