[0002] Static calibrator is a professional equipment used to accurately calibrate and verify electrical parameters such as voltage, current, power, etc. It plays a vital role in fields such as power systems, metrology laboratories and industrial control.

[0003] Most of the existing calibrators are exposed to the outside, so after long-term use, dust and dirt will accumulate in the gaps on the surface, causing deviations in the calibration data and reducing the service life of the calibrator. At the same time, based on this problem, when the calibrator needs to be carried out, it needs to be protected again before transportation, and protective treatment is required during the round trip, which causes a certain degree of cumbersomeness.

[0004] In view of the above, the present application proposes a fully automatic intelligent static calibrator, which can place all the instruments used in a box, and protect the internal structure through the box. When carrying it outside, you only need to fold the box and take it away for use, which is convenient and labor-saving to operate. Utility Model Content

[0044] In order to improve the convenience of using a static calibration instrument, this application proposes a fully automatic intelligent static calibration instrument, which is as follows:

[0045] The present application is mainly composed of a chassis 1 and a base plate module 2, a motor module 3 and an operating table 4 arranged in the chassis 1. Through the cooperation between them, the calibrator is integrated and placed in the chassis 1 for use. The operating table is inside the chassis 1, and the chassis 1 can also be used for protection during non-use periods. It is convenient in transportation and other aspects, and is more conducive to carrying and using when going out.

[0046] For reference Figure 1 The chassis 1 includes an upper structure 11 and a lower structure 12, and the upper structure 11 and the lower structure 12 are connected by a quick-release hinge, so that the upper structure 11 and the lower structure 12 can be quickly installed and disassembled, which is beneficial to maintenance and assembly efficiency.

[0047] For reference Figure 1 , a bottom plate module 2, a motor module 3 and an operating table 4 are arranged in the lower structure 12 of the chassis 1; a hard cotton lining 13 is arranged in the upper structure 11, and the hard cotton lining 13 is adapted to the structure of the top surface of the lower structure 12, and when the upper structure 11 and the lower structure 12 are closed, it plays a protective role. In the existing technology, the bottom plate module 2, the motor module 3 and the operating table 4 are mostly arranged in the upper part of the chassis 1 and exposed to the outside. After long-term use, dirt will accumulate and it is difficult to clean. At the same time, when exposed to the outside for a long time, the loss rate of the external structure is also large; in the present application, the structures required for work are all arranged inside the chassis 1; protection work can be done during non-use to increase the protection between the structures, thereby improving the service life of the equipment.

[0048] For reference Figure 1-2The base plate module 2 includes a base plate 21, a motor driver 22 and support columns 23; the base plate 21 is installed on the inner bottom wall of the lower structure 12 by bolts; the base plate 21 is fully adapted to the size of the inner cavity of the lower structure 12, and is fixed by bolts, which is also convenient for subsequent disassembly and maintenance work; the motor driver 22 is fixedly installed on the base plate 21; there are four support columns 23, which are fixedly connected to the four corners of the base plate 21; the whole forms a bottom frame for supporting the driving parts of the equipment and the setting of the support structure.

[0049] For reference Figure 3 , the motor module 3 comprises a stepper motor 31, a cover-type module 32, a bracket 33 and a flat plate 34; the stepper motor 31 is fixedly mounted on the bottom plate 21, and the cover-type module 32 is arranged on the stepper motor 31; the bracket 33 is mounted on the cover-type module 32 by bolt connection; the overall height of the stepper motor 31 is not higher than the support column 23, and a connection is established between the stepper motor 31 and the motor driver 22 during use, thereby controlling the current in the coil of the stepper motor 31, so that the stepper motor 31 can generate the required torque and speed. For the stepper motor 31, the driver adjusts the current of each phase to accurately control the position of the rotor.

[0050] The stepper motor 31 and the cover-type module 32 usually have standard flange interfaces. Ensure that the flange sizes and hole positions of the two match; align the flange of the stepper motor 31 with the corresponding hole positions on the cover-type module 32 and fix them with screws; the cover-type module 32 is an existing structure, including guide rails, sliders and mounting plates, providing a stable mechanical motion platform to ensure the accuracy of motion transmission after the stepper motor 31 and the cover-type module 32 are connected.

[0051] A bracket 33 is installed on the cover plate type module 32 by means of bolts, and a flat plate 34 is installed on the top of the bracket 33 by means of adapter bolts. The flat plate 34 serves as a loading platform for placing instruments or workpieces to be calibrated.

[0052] For reference Figure 3-4 The operating table 4 is arranged on the top of the supporting column 23 and is adapted to be located at the same horizontal plane as the top of the lower structure 12; wherein the operating table 4 includes a fixed panel 41, a display screen 42, a touch pen 43, a clamp 44 and a sensor 45; the fixed panel 41 is fixedly installed on the top of the supporting column 23; the display screen 42 is arranged in the middle of the fixed panel 41; the touch pen 43 is clamped on the surface of the fixed panel 41; the clamp 44 is fixedly installed on the fixed panel 41; the sensor 45 is detachably arranged in the clamp 44; in the setting, in order to make the sensor 45 correspond to the front and back of the flat plate 34, a slide 5 is opened on the fixed panel 41, and the slide 5 is arranged beside the clamp 44; the bracket 33 passes through the slide 5 from the lower side of the operating table 4, so that the flat plate 34 installed on the bracket 33 is located on the upper side of the operating table 4 and corresponds to the front and back of the sensor 45.

[0053] The clamp 44 is used to clamp and install the sensor 45, which includes a probe frame 441, a jacket 442 and a jacket bolt 443; the probe frame 441 is fixedly installed on the fixed panel 41, the jacket 442 is arranged in the probe frame 441, and the jacket bolt 443 is passed through the top of the probe frame 441 to tighten the sensor 45 inserted in the jacket 442; when the jacket bolt 443 is loosened, the contact pair sensor 45 can be fixed, so that the sensor 45 can be taken out for adjustment.

[0054] The display screen 42 provides a touch or button operation interface, through which the user can set parameters, input operation commands, etc. In order to reduce the inconvenience of operation during touch, a touch pen 43 is set on the fixed panel 41. The interface is operated by the touch pen 43, thereby reducing touch failure and deviation during touch, thereby improving the user experience.

[0056] In the utility model, the working steps of the device are as follows:

[0057] 1. First, release the connection between the upper structure 11 and the lower structure 12 to expose the operating platform 4. If the connection between the upper structure 11 and the lower structure 12 is not released in the early stage, it can play a better protective effect during transportation or handling;

[0058] 2. Secondly, turn on the power supply at the socket 7 in advance, and place the instrument or workpiece to be calibrated on the flat plate 34;

[0059] 3. Then, the internal power is turned on by pressing the button to start working, and the stepper motor 31 moves the flat plate 34 to make precise movements;

[0060] 4. Finally, the verified data is displayed on the display screen 42, and parameter settings and operation command input are performed through the touch pen 43.
