In the first embodiment, please refer to fig. 3-4:

an electric core electrode lug positioning structure comprises

The placing platform 4 is used for placing the battery cell 10;

the lug positioning platform 5 is movably arranged on one side of the placing platform 4, and the height of the lug positioning platform is adjusted along the vertical direction so as to be supported on the lower bottom surface of the battery cell lug 11 to prevent the battery cell lug 11 from being bent;

the spring thimble 2 is movably arranged on the upper surface of the battery cell lug 11 and matched with the testing mechanism 1 to realize the test of the battery cell 10;

the lug positioning platform 5 is provided with a copper block 3 matched with the lower bottom surface of the battery cell lug 11; the lug positioning platform 5 is movably connected with a fixed base 9 on the testing mechanism 1; a height adjusting screw 6 is arranged in the middle of the lug positioning platform 5; the height adjusting screw 6 is in threaded connection with the lug positioning platform 5; the bottom of the height adjusting screw 6 is buckled on the upper surface of the fixed base 9;

because current test equipment does not possess regulatory function, consequently the height between the height of copper billet 3 and the electric core utmost point ear 11 can't cooperate completely for can cause bending of electric core utmost point ear 11 when spring thimble 2 pushes down. Through setting up the height of regulation utmost point ear positioning platform 5 that height adjusting screw 6 can be quick, thereby 6 bottoms of height adjusting screw are supported to detain the height of adjusting utmost point ear positioning platform 5 through rotatory height adjusting screw 6 at unable adjustment base 9 upper surface, and then offset the difference in height between electric core utmost point ear 11 and copper billet 3.

The utility model discloses an in the embodiment, be equipped with a plurality of electric core spacing grooves that set up side by side on the place the platform 4. Thereby can realize the test to a plurality of electric cores 10 simultaneously through setting up a plurality of electric core spacing grooves, raise the efficiency.

In an embodiment of the present invention, the testing mechanism 1 is used for testing the OCV.

The utility model discloses an in the embodiment, because the altitude mixture control in the above-mentioned embodiment is realized through altitude mixture control screw 6, but have a problem, because altitude mixture control screw 6 is single screw only, stability during its regulation can't reach the best effect, probably has the condition of thoughtlessly moving, and a solution is to set up the supporting seat in altitude mixture control screw 6 bottoms to increase the area of contact of bottom and unable adjustment base 9 upper surface, nevertheless the stability of this mode still can't reach the best. Therefore, fixing and adjusting screws 8 can be symmetrically arranged on two sides of the height adjusting screw 6; the thread part of the fixed adjusting screw 8 penetrates through the lug positioning platform 5 and then is in threaded connection with the fixed base 9. The advantage of this kind of mode is realized the spacing of utmost point ear locating platform 5 from both sides, makes it can not produce when being extruded by spring thimble 2 and rocks. On the other hand height-adjusting screw 6 gives 5 ascending holding power of utmost point ear location platform, through the fixed adjusting screw 8 of screwing downwards, can give 5 decurrent pressures of utmost point ear location platform to realized utmost point ear location platform's fixed, and can specifically adjust holistic height according to actual conditions, can not produce and rock.

The utility model discloses an in the embodiment, it is equipped with fastening nut 7 to lie in utmost point ear location platform 5 upper surface on the altitude mixture control screw 6. The advantage of setting up fastening nut 7 is that can further promote the stability of being connected between height-adjusting screw 6 and utmost point ear location platform 5 to realize better spacing effect.

In an embodiment of the present invention, the spring thimble 2 is provided with a spring buffering device inside.

The utility model discloses a utmost point ear location platform that can go up and down the activity regulation to compensate the difference in height of utmost point ear position, thereby effectually avoid pressing down bending that causes utmost point ear when electric core test spring thimble. Through the spring buffer device that the spring thimble inside set up, when reducing the test the punching press mar that the impact caused in the twinkling of an eye to the utmost point ear when the spring thimble pushes down.

The above mentioned is only the embodiment of the present invention, and not the limitation of the patent scope of the present invention, all the equivalent transformations made by the contents of the specification and the drawings, or the direct or indirect application in the related technical field, are included in the patent protection scope of the present invention.
