Description

Technical Field

[0001] The utility model relates to the technical field of electric meter detection, and particularly relates to an electric meter testing device. Background Art

[0002] As a device for measuring electric energy consumption, the electric energy meter belongs to a measuring product, which is used for electric energy measurement and billing and is the basis for the orderly development of electric power operation management. As a measuring product, the electric energy meter is related to the livelihood issues of every household, and has quite high requirements for the accuracy and reliability of electric power measurement. The fairness of measurement must be ensured. For this reason, national institutions have formulated relevant standards and set up inspection and verification departments. The electric energy meter products need to pass the inspection and certification of the authoritative department before they can be put on the market. Therefore, the electric energy meter needs to be tested before leaving the factory to meet the standard requirements.

[0003] At present, in the existing testing methods, it is common for staff to test electric energy meters one by one, with low testing efficiency. In addition, there are also workbenches used for testing, but the positioning accuracy is not high, and the probes cannot make good contact with the electric energy meters. Content of the Utility Model

[0004] In view of the problems and deficiencies in the prior art, the utility model provides an electric meter testing device.

[0005] The technical solution of the utility model is as follows:

[0006] An electric meter testing device includes a testing table, a plurality of testing instruments arranged at intervals along the length direction of the testing table, and a handling component arranged on one side of the testing table; the handling component is used to place the electric energy meter at the corresponding position on the testing table;

[0007] A plurality of guiding holes are arranged in parallel at intervals on the testing table. The extending direction of the guiding holes is parallel to the width direction of the testing table and is directly opposite to the testing instruments; a positioning component is slidably arranged in the guiding holes and is used to drive the electric energy meter to move back and forth to realize plugging or separating from the testing instrument, and includes a driving member, a bracket and a plurality of sliders;

[0008] The plurality of sliders are arranged at intervals along the length direction of the testing table, are connected into a whole by the bracket, and are respectively slidably matched with the guiding holes. The tops of the sliders are connected with a fixing component for fixing the electric energy meter;

[0009] The driving member is a linear driving member, which is fixed at the rear side of the testing table and the moving direction is parallel to the length direction of the guiding holes, and is used to drive the bracket to move back and forth.

[0010] During testing, the electricity meter is carried onto the fixing component by the handling component. Then, the driving part operates, driving the support to move back and forth, thereby driving a plurality of sliders connected thereto to slide back and forth along the extending direction of the guiding holes. Further, it drives the electricity meter fixed on it by the fixing component to slide towards the tester until the test jack of the electricity meter contacts the probe of the tester. The driving part stops operating for testing. After the testing is completed, the driving part moves in the reverse direction, driving the electricity meter to move backward through the positioning component. When it moves to the rearmost position, the driving part stops operating, and the handling component operates to remove the tested electricity meter from the fixing component.

[0011] In a specific embodiment, the fixing component includes an electricity meter connecting plate and a slider connecting plate connected up and down, and the electricity meter connecting plate can move left and right relative to the slider connecting plate. Specifically, a lower adjusting plate and an upper adjusting plate are respectively provided at the right ends of the slider connecting plate and the electricity meter connecting plate, and an adjusting shaft is connected between the lower adjusting plate and the upper adjusting plate for driving the electricity meter connecting plate to move left and right relative to the slider connecting plate. The electricity meter connecting plate is connected to the slider connecting plate through an upper connecting hole, and the upper connecting hole is an oblong hole extending left and right.

[0012] Specifically, the lower adjusting plate and the upper adjusting plate are respectively arranged on the top surfaces of the slider connecting plate and the electricity meter connecting plate, in the middle of their width directions, and are aligned left and right. One end of the adjusting shaft is rotatably connected to the lower adjusting plate, and one end is threadedly connected to the upper adjusting plate. Specifically, one end of the adjusting shaft is a bolt with threads. The threaded end passes through the upper adjusting plate and is in threaded cooperation with the upper adjusting plate. The other end passes through the lower adjusting plate. In practice, a round hole is provided on the lower adjusting plate, and the adjusting shaft has a clearance fit with it. An axial positioning part is provided on the shaft end between the upper and lower adjusting plates, so that the adjusting shaft only makes circumferential rotation and does not make axial movement, thereby driving the electricity meter connecting plate to move left and right, thereby adjusting the left and right positions of the electricity meter fixed on the electricity meter connecting plate. At the same time, through the guiding action of the upper connecting hole, the electricity meter connecting plate and the slider connecting plate move linearly in the left and right directions, thereby adjusting the left and right direction positions of the electricity meter, ensuring that each probe of the tester can make good contact with the electricity meter opposite to it.

[0013] In order to fix the electricity meter, a positioning part is provided on the electricity meter connecting plate to fix the electricity meter.

[0014] To improve stability, two linear driving parts are provided, which are arranged at intervals along the length direction of the test bench. Specifically, the linear driving part is one of a pneumatic push rod, a hydraulic push rod or an electric push rod. In the present invention, an electric push rod is preferably used.

[0015] The beneficial effects of the present invention are:

[0016] 1) A guiding hole is provided on the test bench. A positioning component is slidably fitted in the guiding hole. The positioning component includes a driving member, a bracket, and a slider. By providing the guiding hole and the slider slidably fitted therewith, the positioning accuracy between the watt-hour meter and the tester is improved, ensuring good contact between the watt-hour meter and the tester probe.

[0017] 2) The fixing component is composed of a slider connecting member and a watt-hour meter connecting member arranged vertically. And a left-right adjustment is performed between the slider connecting member and the watt-hour meter connecting member through an adjustment shaft, facilitating fine adjustment of the fixing component to ensure that the watt-hour meters on multiple fixing components arranged in a straight line can all have good contact with the tester.

[0028] See Figure 4 As shown, during the test, the electric energy meter is carried onto the fixing component 5 by the handling component 3, and then the driving member 41 works to drive the bracket 42 to move back and forth, so as to drive the plurality of sliders 43 connected thereto to slide back and forth along the extending direction of the guide hole 11, and further drive the electric energy meter fixed on it through the fixing component 5 to slide towards the tester 2 until the test jack of the electric energy meter contacts the probe of the tester 2, and the driving member 41 stops working for testing. After the test is completed, the driving member 41 moves in the reverse direction, and drives the electric energy meter to move backward through the positioning component 4.
