Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model tester for electric energy meter.
Embodiment
Below with reference to the drawings and the specific embodiments, the utility model is elaborated.
The utility model tester for electric energy meter is for the check and correction of electric energy meter 90, and as shown in Figure 1, described tester for electric energy meter comprises that table drags 10, guide rail 30, cylinder 50 and control module 70.
Described table drags 10 for carrying the electric energy meter 90 of meter to be corrected, and table drags on 10 end face 11 and is formed with terminal 12, for being connected with the corresponding port of electric energy meter 90 of meter to be corrected.Described table drags on 10 and is also formed with flexible member 14, and as spring, shell fragment etc., for elastic-restoring force is provided, the electric energy meter 90 after calibration is completed drags 10 automatically to separate with table.In the present embodiment, described flexible member 14 is spring, described flexible member 14 stretches out in table and drags 10 to be formed with outside the end face 11 of terminal 12, it is under the state of nature that is not subject to External Force Acting, and described flexible member 14 stretches out length outside end face 11 and is not less than terminal 12 and stretches out in the length outside end face 11.Described flexible member 14 can be one or more above, and preferably, described flexible member 14 is multiple, is distributed in symmetrically described table and drags on 10.
Described cylinder 50, for promoting the electric energy meter 90 of meter to be corrected, makes it drag the terminal 12 on 10 to be connected with table.Described control module 70 links with cylinder 50, controls the displacement of electric energy meter 90.In the present embodiment, in the draft tube 52 of described cylinder 50, be connected with throttling valve 54, by regulating pressure and the speed of throttling valve 54 control cylinder 50 air inlets, and then can change the power that cylinder 50 is exported.The outer end of the piston rod 56 of described cylinder 50 is connected with push pedal 58, moves for the electric energy meter 90 that promotes meter to be corrected.The outer surface smoother of described push pedal 58, thus while contact with the electric energy meter 90 of meter to be corrected, the distribution of force of electric energy meter 90 is even, keeps electric energy meter 90 smoothly to move.
Described guide rail 30 drags between 10 at cylinder 50 and table, and one of guide rail 30 is rectified push pedal 58, and another proper his-and-hers watches drag 10 end face 11.Described guide rail 30 is tentatively decided to be and guides the movement of electric energy meter 90 for the electric energy meter 90 to meter to be corrected, make the electric energy meter 90 of meter to be corrected drag intact being connected of terminal 12 energy on 10 with table.Between described guide rail 30, form the electric energy meter 90 that space 32 holds meter to be corrected, the size in described space 32 can be adjusted, to adapt to the calibration of electric energy meter 90 of different size.
When the utility model electric energy meter 90 calibration devices use, the electric energy meter of meter to be corrected 90 is placed in the space 32 of guide rail 30, electric energy meter 90 is able to Primary Location, then start cylinder 50, under the doing of cylinder 50, described push pedal 58 direction guiding rails 30 of the protruding promotion of piston rod 56 move, and contact and drive electric energy meter 90 to drag 10 to move along guide rail 30 towards table in moving process with the electric energy meter 90 of meter to be corrected.In this process, first electric energy meter 90 touches table and drags the flexible member 14 on 10, due to the thrust of cylinder 50 to electric energy meter 90, described flexible member 14 is subject to force compresses, table drags terminal 12 on 10 correspondingly to insert in the port of electric energy meter 90 and is electrically connected with electric energy meter 90 formation, so can proofread and correct electric energy meter 90.In cylinder 50 promotes process that electric energy meter 90 moves, whether described control module 70 detects cylinder 50 and electric energy meter 90 is pushed and put in place, when electric energy meter 90 and table drag 10 to contact, the port of electric energy meter 90 and table drag 10 be connected intact, control module 70 is given an order, and cylinder 50 stops doing moving, and push pedal 58 no longer promotes electric energy meter 90 but keeps pressing down electric energy meter 90, maintain electric energy meter 90 and drag being connected of 10 terminal 12 with table, until electric energy meter 90 completes correction.
After electric energy meter 90 has been calibrated, control module 70 starts cylinder 50 again, cylinder 50 does its piston rod 56 is retracted, drive push pedal 58 to retract separates with electric energy meter 90 simultaneously, now, because the acting force of cylinder 50 disappears, table drags the flexible member 14 elasticity recovery deformation on 10, forming outside elastic-restoring force promotion electric energy meter 90 moves towards cylinder 50 directions, so table drags the terminal 12 on 10 to deviate from from the port of electric energy meter 90, electric energy meter 90 drags 10 to separate completely with table, can easily the electric energy meter after proofreading and correct 90 be taken out and carry out next operation, described table drags 10 corrections that also can be advantageously used in next electric energy meter 90.
The utility model utilizes the promotion of cylinder 50 to realize the fixing calibration of electric energy meter 90, and realize the automatic separation after electric energy meter 90 calibrations by the elastic-restoring force of flexible member 14, simple in structure, easy to operate, effectively simplify the handling of electric energy meter 90 in calibration, promote the calibration efficiency of electric energy meter 90.It should be noted that; the utility model is not limited to above-mentioned embodiment; according to creative spirit of the present utility model; those skilled in the art can also make other variations; the variation that these do according to creative spirit of the present utility model, within all should being included in the utility model scope required for protection.
