Description

Technical Field

[0001] The utility model relates to the field of balance calibration, in particular to an integrated balance calibration device. Background Art

[0002] A balance is a weighing instrument, which is mainly composed of a balance beam supported by a fulcrum at the center of the beam to form two arms, with a pan hanging on each arm. One pan contains a weight or other object of known mass, and the other pan contains the object to be measured. The deflection of the pointer fixed on the beam when it is not swinging and pointing to the middle scale indicates the mass of the object to be measured.

[0003] Since a balance is a high-precision instrument, it will have certain errors after being used for a period of time or when it is not used for a long time, so it needs to be calibrated regularly.

[0004] The existing method for calibrating a balance usually involves placing weights of the same mass on two trays of the balance, and then manually adjusting the balance according to the direction of the pointer so that the pointer points to the middle. When placing the weights, due to manual placement of the weights, it is impossible to ensure that the weights are placed on the two trays at the same time, resulting in the balance swinging after the weights are placed on the trays. At this time, it is necessary to wait until the balance is completely still before manual calibration can be performed, resulting in a long time required for calibrating the balance, which is likely to delay subsequent measurement work.

[0005] Therefore, it is necessary to provide a new integrated balance calibration device to solve the above technical problems. Utility Model Content

[0017] Compared with the related art, the integrated balance calibration device provided by the utility model has the following beneficial effects:

[0018] 1. When the utility model calibrates the balance, the motor is controlled to rotate, so that it drives the winding rod connected to it to rotate.

[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0028] See also Figures 1 to 5 The integrated balance calibration device provided by the embodiment of the utility model includes: a fixing frame 1, a calibration component 2 and an adjustment component 3.

[0029] In the embodiment of the utility model, please refer to Figures @ and @, the calibration component 2 is located on the fixed frame 1, and the calibration component 2 includes a mounting box 21, a winding rod 22, a traction rope 23, a weight 24 and a gear 25. A slidingly connected mounting box 21 is provided on the top of the fixed frame 1, and two rotatably connected winding rods 22 are provided in the mounting box 21, and the traction rope 23 is wound on the winding rod 22, and the other end of the traction rope 23 is provided with a weight 24 of the same weight, and two rotatably connected gears 25 are provided on the mounting box 21, and the gears 25 are respectively fixedly connected to one end of the winding rod 22 on the same side, and the gears 25 are meshed with each other. The calibration component 2 also includes a motor 26, and a motor 26 is provided on one side of the mounting box 21, and the output end of the motor 26 is fixedly docked with one end of any one of the winding rods 22. The calibration component 2 also includes a control panel 27, and a control panel 27 for controlling the motor 26 is provided on the top of the mounting box 21, and a plurality of buttons are provided on the control panel 27.

[0030] It should be noted that before calibrating the balance, first place the balance under the fixed frame 1 and ensure that the two trays of the balance are directly under the two weights 24. Then, power on the device and use the control panel 27 to control the operation of the motor 26. When the motor 26 is running, it can drive the winding rod 22 connected thereto to rotate, and the winding rod 22 can rotate the other winding rod 22 at the same time through the transmission effect of the two gears 25 during the rotation. During the rotation of the two winding rods 22, the traction rope 23 can be lowered to make the weights 24 fall on the tray of the balance at a uniform speed. Then, according to the direction of the pointer on the balance, manually calibrate the balance until the pointer points to the middle, that is, the calibration of the balance is completed. Then, control the motor 26 to reverse, and use the two flipped winding rods 22 to wind up the traction rope 23, so that the weights 24 leave the tray of the balance at the same time. Then, the balance can be used to measure objects.

[0031] In the embodiment of the utility model, please refer to Figures @ and @, the adjustment component 3 is located below the mounting box 21, the adjustment component 3 includes a mounting frame 31, a limiting frame 34 and a pulley 35, mounting frames 31 are provided on both sides of the bottom of the mounting box 21, and limiting frames 34 are provided on the mounting frames 31, and pulleys 35 rotatably connected are provided on the mounting frames 31, the adjustment component 3 also includes limiting grooves 32 and mounting grooves 33, limiting grooves 32 are provided on the mounting frames 31, and a plurality of mounting grooves 33 are provided on both sides of the top of the mounting frame 31, and the mounting grooves 33 are respectively located on both sides of the limiting grooves 32, the limiting frames 34 are located in the mounting grooves 33, and the pulleys 35 are located in the limiting grooves 32.

[0032] It should be noted that the pulley 35 can support the traction rope 23 so that the weight 24 can fall on the balance tray more stably. After the balance is placed under the fixed frame 1, the limit frame 34 is picked up and moved according to the positions of the two trays of the balance, and it is stuck in the installation groove 33 of the installation frame 31 just above the tray. At this time, due to the change of the pulley 35, the fulcrum of the traction rope 23 changes, thereby changing the position of the weight 24, so that the weight 24 is located just above the balance tray. After that, the weight 24 is put down, so that the weight 24 can fall accurately on the balance tray, which is convenient for calibration and measurement of the balance.

[0033] It is worth noting that when the position of the limit frame 34 is moved, the limit frames 34 located on both sides of the installation box 21 need to be moved simultaneously to prevent the positions of the two weights 24 from being asymmetrical, which may affect the calibration measurement results of the balance.

[0034] In the embodiment of the present utility model, please refer to FIG. 1 and FIG. 2 , a fixedly connected lifting rod 4 is provided at the bottom of the fixing frame 1 , and a base 41 is installed at the bottom end of the lifting rod 4 .

[0035] It should be noted that: according to the height of the calibrated balance, the lifting rod 4 can be used to lift the fixing frame 1 so that the weight 24 can be placed on the balance tray more quickly and smoothly. The base 41 has a large area, so the device can be stably placed on the workbench.

[0036] The working principle of the integrated balance calibration device provided by the utility model is as follows:

[0037] First, place the device on a workbench, then place the balance to be calibrated on one side of the device, and then adjust the height of the fixing frame 1 through the lifting rod 4 so that the weight 24 is located above the balance;

[0038] Then, according to the positions of the two trays of the balance, the limiting frames 34 on the mounting frames 31 on both sides of the mounting box 21 are picked up at the same time and moved. During the movement, it is necessary to ensure that the positions of the two limiting frames 34 are symmetrical to each other. Then, the limiting frames 34 are stuck in the mounting grooves 33 of the mounting frames 31 just above the trays. At this time, due to the change of the pulley 35, the fulcrum of the traction rope 23 changes, thereby changing the position of the weight 24, so that the weight 24 is located just above the balance tray;

[0039] After that, the device is powered on, and the control panel 27 is used to control the operation of the motor 26. When the motor 26 is running, it can drive the winding rod 22 connected thereto to rotate. During the rotation of the winding rod 22, the transmission effect of the two gears 25 can make the other winding rod 22 rotate at the same time. During the rotation of the two winding rods 22, the traction rope 23 can be lowered, so that the weight 24 falls on the tray of the balance at a uniform speed. Then, according to the direction of the pointer on the balance, the balance is manually calibrated until the pointer points to the middle, that is, the calibration of the balance is completed. Then, the motor 26 is controlled to reverse, and the traction rope 23 is reeled in by the two flipped winding rods 22, so that the weight 24 leaves the tray of the balance at the same time, and then the balance can be used to measure objects.

[0040] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0041] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
