Description

Technical Field

[0001] The invention belongs to the technical field of electric power equipment detection, and in particular relates to an electric power metering equipment detection platform capable of automated tooling. Background Art

[0002] Electricity metering equipment is a device used to measure, record and control electric energy consumption in power systems, among which electric energy meters are the most common electric energy metering equipment. At present, electric energy meters using wiring terminals need to undergo an automated connectivity test on an electric energy metering equipment test bench before leaving the factory to ensure the stability of the electrical connection of the wiring terminals of the electric energy meter.

[0003] A Chinese patent discloses an electric energy meter test bench (authorization announcement number CN205826855U), in which different terminal modules are selected according to different electric energy meters. The terminal modules are detachably mounted on the test bench base, and the first terminal of the test bench base and the second terminal of the terminal module are interference fit, and the two are tightly connected together to achieve a stable electrical connection. The back plate of the test bench base is tilted, and the electric energy meter leans on the back plate. The back plate can be mounted on the stand by bolts, or the back plate and the stand can be integrally formed. The probe of the terminal module is inserted into the input end of the electric energy meter to achieve electrical connection between the terminal module and the electric energy meter. There is no need to connect the terminal module and the electric energy meter with wires, which eliminates the trouble of connecting multiple wires. Different electric energy meters have different input end arrangements. It is only necessary to replace the terminal module and adjust the corresponding output voltage to perform power-on detection on different electric energy meters, and realize power-on detection of multiple electric energy meters on one electric energy meter test bench.

[0004] Although the above-mentioned device adopts the method of preset probe to eliminate the burden of connecting the external test wire to the electric energy meter, the staff still needs to actively connect the probe with the input port of the electric energy meter, which requires the tester to have relatively proficient plugging and unplugging experience. Otherwise, it is easy for the probe to be bent due to misaligned plugging, or the input port of the electric energy meter to be damaged due to misaligned plugging, which increases the difficulty of testing the electric energy meter.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] See also Figure 1 - Fig. 9 , the present invention provides a technical solution:

[0046] An electric metering equipment test bench capable of automated tooling includes an electric test bench 100, a power meter calibrator 200 is hingedly connected to the surface of the electric test bench 100, a probe module 300 is electrically connected to the surface of the power meter calibrator 200, and an automated guiding mechanism 400 is installed on the surface of the power meter calibrator 200;

[0047] The probe module 300 includes a mounting bar fixedly connected to the surface of the electric energy meter calibrator 200 by bolts, and evenly distributed probes are fixedly connected to the top of the mounting bar. The specifications, quantity and position arrangement of the probes need to be customized according to the positions of the terminal sockets of the electric energy meter being tested. The specific specifications, quantity and position arrangement need to be selected according to actual needs, which will not be elaborated here. The interface of the probe and the electric energy meter calibrator 200 is electrically connected through a wire; when the probe is connected to the terminal of the electric energy meter, the electric energy meter calibrator 200 is connected to the electric energy meter through the wire and the probe, and the staff can test the specific parameter performance of the electric energy meter through the electric energy meter calibrator 200 through the existing testing method.

[0048] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, the automated guiding mechanism 400 includes a centering guiding mechanism 410 fixedly connected to the top of the electric energy meter calibrator 200, a first sliding frame 420 is fixedly connected to the surface of the centering guiding mechanism 410, a second sliding frame 430 is slidably connected to the inner side of the first sliding frame 420, a sliding sleeve 440 is slidably connected to the inner side of the second sliding frame 430, a correction sleeve 450 is rotatably connected to the inner side of the sliding sleeve 440, and the correction sleeve 450 is sleeved on the surface of the probe module 300; the horizontal cross-sectional shape of the first sliding frame 420 is U-shaped, the opening cross-sectional size of the first sliding frame 420 is the same as the vertical cross-sectional size of the second sliding frame 430, and the staff can quickly install the corresponding number of correction sleeves 450 according to the needs of the probes to meet the straightening requirements of different numbers of probes.

[0049] During the process of the mounting plate 412 being lifted and lowered, the mounting plate 412 drives the first sliding frame 420 to be lifted and lowered accordingly, the first sliding frame 420 drives all the second sliding frames 430 to be lifted and lowered, the second sliding frame 430 drives the sliding sleeve 440 to be lifted and lowered, the sliding sleeve 440 drives the correction sleeve 450 to be lifted and lowered, the correction sleeve 450 is lifted and lowered along the surface of the probe, when the probe is partially bent or offset, the correction sleeve 450 straightens the probe by squeezing force during the lifting and lowering process, so that the probe can be vertically inserted into the socket of the electric energy meter terminal;

[0050] When the staff needs to adjust the position of the correction sleeve 450 according to the position of the probe, the staff only needs to manually control the electric cylinder 411 to drive the mounting plate 412 to rise, the mounting plate 412 drives the first sliding frame 420 to rise, the first sliding frame 420 drives all the second sliding frames 430 to rise, the second sliding frame 430 drives the sliding sleeve 440 to rise, and the sliding sleeve 440 drives the correction sleeve 450 to rise above the probe. At this time, the staff can adjust the horizontal coordinate of the correction sleeve 450 by sliding the second sliding frame 430 inside the first sliding frame 420, and adjust the longitudinal coordinate of the correction sleeve 450 by sliding the sliding sleeve 440 inside the second sliding frame 430 to meet the correction needs of probes in different positions.

[0051] like Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the surface of the correction sleeve 450 is provided with a spiral groove 451, and the automatic guiding mechanism 400 also includes a cleaning mechanism 460, which includes an annular grinding sleeve 461 and a rectangular rod 462. The annular grinding sleeve 461 is embedded and installed on the inner side of the correction sleeve 450, and the rectangular rod 462 is fixedly connected to the bottom of the sliding sleeve 440. The surface of the rectangular rod 462 is provided with a rectangular sleeve 463 in contact with the electric energy meter calibrator 200, and the surface of the rectangular sleeve 463 is fixedly connected with a guide block 464 slidably connected to the spiral groove 451. The cleaning mechanism 460 uses the lifting and lowering trend of the correction sleeve 450 to bring The dynamic correction sleeve 450 rotates to grind and peel off the unevenness on the probe surface caused by rust or excessive current, and can intercept and retain the grinding debris inside the correction sleeve 450, so that the flat and clean probe part is plugged together with the electric energy meter, further improving the stability when the electric energy meter is connected to the electric energy meter calibrator 200. At the same time, the correction sleeve 450 rotates to compress the bending part of the probe, which can also reduce the burden of the correction sleeve 450 on straightening the probe, effectively reducing the probability of deformation of a certain part of the correction sleeve 450 due to long-term squeezing of the probe, thereby extending the service life of the correction sleeve 450.

[0052] A rubber spring 465 is arranged between the rectangular rod 462 and the rectangular sleeve 463. The rubber spring 465 is in a compressed state at this time, which can ensure that the rectangular sleeve 463 is always tightly fitted to the surface of the electric energy meter calibrator 200, so as to ensure that the correction sleeve 450 can rotate stably during the lifting process; an annular cavity 452 is provided on the inner side of the correction sleeve 450, and the annular grinding sleeve 461 is embedded in the inner part of the annular cavity 452, which can concentrate and retain impurities ground from the probe surface, which can not only reduce the probability of external pollution, but also can It is convenient for the staff to carry out centralized cleaning later; the vertical cross-section of the ring-shaped polishing sleeve 461 is in the shape of an hourglass, and the ring-shaped polishing sleeve 461 is a member made of nitrile rubber material, which can ensure that the ring-shaped polishing sleeve 461 can surround and elastically polish the protruding part of the probe, so that the probe can pass through the correction sleeve 450 normally; the surface of the ring-shaped polishing sleeve 461 is provided with an airbag ring 466, and the airbag ring 466 is in an expanded state at this time, which can increase the polishing pressure of the ring-shaped polishing sleeve 461 on the probe surface, so as to improve the polishing effect of impurities on the probe surface;

[0053] In the process of the sliding sleeve 440 driving the correction sleeve 450 to rise and fall, the sliding sleeve 440 synchronously drives the rectangular rod 462 to rise and fall. At this time, the relative positions of the rectangular rod 462 and the rectangular sleeve 463 change, and the rubber spring 465 synchronously pushes the rectangular sleeve 463 so that the rectangular sleeve 463 abuts against the surface of the electric energy meter calibrator 200. In this process, the relative positions of the rectangular sleeve 463 and the correction sleeve 450 change. The correction sleeve 450 rotates along the sliding sleeve 440 through the spiral groove 451 under the guidance of the guide block 464. The correction sleeve 450 drives the annular grinding sleeve 461 to flexibly and rotationally grind the part passing through the probe, which can quickly grind and peel off the unevenness on the probe surface caused by rust or excessive current, which can increase the effective contact area between the probe and the electric energy meter terminal, so that the connection between the electric energy meter calibrator 200 and the electric energy meter is more stable.

[0054] like Figure 4 and Fig. 9 As shown, the centering guide mechanism 410 includes an electric cylinder 411 fixedly connected to the top of the electric energy meter calibrator 200, the surface of the electric cylinder 411 is fixedly connected to a mounting plate 412, the first slide frame 420 is fixedly connected to the bottom of the mounting plate 412, the surface of the mounting plate 412 is provided with a sliding cavity 413, the inner side of the sliding cavity 413 is rotatably connected to a bidirectional lead screw 414, the surfaces of the two opposite threads of the bidirectional lead screw 414 are both threadedly connected to the sliding cavity 413 and slidably connected to a threaded sleeve 415, one end of the threaded sleeve 415 passes through the sliding cavity 413, and the thread One end of the sleeve 415 is fixedly connected to a clamping plate 416, and the two clamping plates 416 are symmetrically distributed on both sides of the center point of the mounting plate 412. The bottom of the mounting plate 412 is fixedly connected to a servo motor 417, and the end of the output shaft of the servo motor 417 and the surface of the bidirectional lead screw 414 are fixedly connected to bevel gears 418 that are meshed with each other. The centering guide mechanism 410 can self-calibrate the relative position of the electric energy meter and the probe module 300, and can automatically drive the electric energy meter and the probe module 300 to be plugged in or separated, so as to achieve the purpose of automatic operation.

[0055] The vertical cross-sectional shapes of the sliding cavity 413 and the contact parts of the threaded sleeve 415 and the sliding cavity 413 are both matching rectangles, which can prevent the threaded sleeve 415 from rotating along with the bidirectional screw 414 to ensure that the clamping plate 416 can smoothly approach or move away from the electric energy meter; the opposite ends of the two clamping plates 416 are provided with resistance increasing grooves 419, and the corners of the clamping plates 416 and the resistance increasing grooves 419 are rounded, which can increase the clamping friction of the clamping plates 416 on the resistance increasing grooves 419, so as to improve the stability of the electric energy meter and the probe module 300 when being plugged in or out.

[0056] When the staff needs to lock the electric energy meter in the center, the staff only needs to manually control the servo motor 417 to rotate in the corresponding direction, the servo motor 417 drives the bevel gear 418 connected thereto to rotate, the bevel gear 418 drives another bevel gear 418 to rotate, the other bevel gear 418 drives the bidirectional lead screw 414 to rotate, the bidirectional lead screw 414 drives the two threaded sleeves 415 to slide toward each other along the sliding cavity 413 through two opposite threads, the two threaded sleeves 415 respectively drive the clamping plates 416 connected thereto to move toward each other, until the two clamping plates 416 cooperate to clamp the electric energy meter in the center;

[0057] When the staff needs to connect or separate the electric energy meter from the probe module 300, the staff only needs to manually control the electric cylinder 411 to retract or extend, and the electric cylinder 411 will drive the mounting plate 412 to descend or rise, and the mounting plate 412 will drive the threaded sleeve 415 and the clamping plate 416 to descend or rise through the sliding cavity 413. At this time, the two clamping plates 416 cooperate to clamp and drive the electric energy meter to descend or rise, so that the electric energy meter can be smoothly connected or separated from the probe module 300.

[0058] Working principle: When the staff needs to test the performance of the electric energy meter, the staff only needs to place the corresponding electric energy meter on the top of the first sliding frame 420 and fit it together with the mounting plate 412. The staff can first clamp the electric energy meter in the center through the centering guiding mechanism 410, so that the terminal socket of the electric energy meter is aligned with the probe on the probe module 300, and then drive the electric energy meter to move downward at a uniform speed, so that the probe moves toward the electric energy meter and is plugged into the terminal socket of the electric energy meter. Then the staff can test the performance of the electric energy meter normally through the electric energy meter calibrator 200. During this process, the centering guiding mechanism 410 can not only align the terminal socket of the electric energy meter with the probe on the probe module 300 by itself, but also drive the electric energy meter to be smoothly connected to the probe module 300 by itself, effectively reducing the probability of bending or displacement of the probe module 300 due to misaligned plugging.

[0059] It should be noted that the electrical test bench 100, the energy meter calibrator 200, the probe, the wire, the electric cylinder 411, the bidirectional screw 414 and the servo motor 417 in the above description are all devices with relatively mature application of existing technologies. The specific models can be selected according to actual needs. At the same time, the electrical test bench 100, the energy meter calibrator 200, the electric cylinder 411 and the servo motor 417 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0060] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
