Example Embodiment

[0019] Example 1: Such as Figure 1-2 As shown, the present invention provides an electronic balance base, including: a housing 1, an adjusting screw 2, an adjusting gear 3, a driving motor 4, a spectrum transmitter 5, a disc level 7, a spectrum receiver 6, an electronic gyroscope 8. The control module 9, the adjustment button 11 and the power supply 10; the housing 1 is a hollow rectangular parallelepiped, four threaded holes are provided at the four corners of the bottom plate, the adjusting screws 2 are four, the upper part is a gear, and the lower part is a thread. Are arranged in the four threaded holes; the adjusting gear 3 and the driving motor 4 are three, and the gears of the driving motor 4, the adjusting gear 3 and the adjusting screw 2 are connected in turn; the spectrum emitter 5 is arranged in On the bottom plate of the housing 1, the spectrum receiver 6 is arranged on the top plate of the housing 1, the disc level 7 is arranged between the spectrum receiver 6 and...

Example Embodiment

[0029] Embodiment 2: As a further improvement to Embodiment 1, the control module 9 is a PLC module or an Arduino module. The driving motor 4 is a forward and reverse stepping motor or a forward and reverse servo motor; the diameter of the bottom end of the adjustment screw 2 is gradually reduced, which is beneficial to reduce the friction between the adjustment screw 2 and the platform and improve the adjustment sensitivity; The balance base also includes a manual adjustment knob 12, which is connected to the adjustment gear 3. The top plate of the electronic balance is provided with an observation window. The operator can observe the disc-shaped level 7 from the top plate of the electronic balance. Manual leveling is performed when there is no power or the device fails; an adjusting nut is fixed on the bottom plate of the housing 1, and the adjusting screw 2 matches the adjusting nut to increase the service life and adjusting accuracy of the adjusting screw 2; The power sourc...

Abstract

The invention discloses an electronic balance base. The electronic balance base comprises a housing, adjustment screws, adjustment gears, driving motors, a spectrum emitter, a disc-shaped horizontal rule, a spectrum receiver, an electronic gyroscope, a control module, an adjustment button and a power supply, wherein the four corners of the base plate of the housing are each provided with a threaded hole, the upper portions of the adjustment screws are provided with gears, the lower portions of the adjustment screws are provided with threads, and the adjustment screws are arranged on the threaded holes; the driving motors, the adjustment gears and the gears of the adjustment screws are successively in transmission connection; the disc-shaped horizontal rule is arranged between the spectrum receiver and the spectrum emitter; and the electronic gyroscope is arranged at the center of the base plate of the housing. According to the electronic balance base, leveling work of the whole electronic balance base can be automatically and rapidly carried out under the control of the control module simply by pressing the adjustment button without manual intervention, and thus the work efficiency and the leveling precision are improved.

Description

technical field [0001] The invention relates to the technical field of balance adjustment, in particular to an electronic balance base. Background technique [0002] The balance needs to be leveled before use, and this step is especially important for high-precision electronic balances. At present, the level calibration of commonly used electronic balances is generally done manually. Not only is the accuracy difficult to guarantee, but also the operation is very cumbersome, and it will delay the user's time. Therefore, it is necessary to develop an electronic balance base that can automatically adjust the level. Contents of the invention [0003] The object of the present invention is to provide an electronic balance base to solve the above-mentioned problems in the prior art, so that the electronic balance can realize automatic level calibration. [0004] In order to achieve the above object, the present invention provides the following scheme: the present invention pro...
