Description
Technical Field
The utility model belongs to test technology field, concretely relates to battery capability test fixed bolster.
Background
When the single battery cell is tested, if the connecting line of the equipment and the current guider (tab) of the battery cell are not tightly connected and the connection mode is incorrect, the local resistance is overlarge, so that the current is heated too fast when passing through the tab, and abnormity appears. Secondly, the excessive contact resistance may cause the voltage detected by the device to be not the actual voltage of the battery cell, which makes the battery cell unable to perform a complete charging and discharging process. In a severe case, if the voltage detected in the constant-current constant-voltage charging process is greater than the actual voltage of the battery cell, the battery cell enters a constant-voltage charging stage too early in the charging process, so that the constant-voltage stage with a small ratio of time originally is too large, and the overall charging time is 1-2 times higher than the expected time.
It is known that the capacities of the same battery cell are different in the charging and discharging processes with different multiplying powers. The shorter the charging time, the less the capacity of the battery cell to be fully charged, and conversely, the longer the charging time, the more the capacity. And if the contact resistance between the battery cell and the connecting wire is too large and the resistance is too high, the test data of multiplying power charge and discharge is not accurate, and the test standard and the customer requirement are not met.
In the prior art, the tab of the battery needs to maintain a certain oblique angle, and in order to ensure that the angle is not changed after the connecting wire is connected with the tab of the battery, the connecting wire needs to be fixed by a binding belt. However, the fixing mode cannot ensure that the oblique angle of the tab is not changed or stressed when the battery moves; furthermore, batteries connected in this way cannot be removed, and when it is necessary to replace the batteries inside the box, the external batteries also need to be removed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a battery capability test fixed bolster in order to overcome prior art's not enough.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a battery performance test fixture, comprising:
the vertical plate comprises a first transverse plate, a vertical plate fixed on the first transverse plate, a second transverse plate fixedly connected to the end portion of the vertical plate, a connecting plate hinged to one end, far away from the vertical plate, of the second transverse plate, clamps arranged on the connecting plate, a supporting plate arranged on the first transverse plate at intervals and a fixing plate movably arranged on one side, opposite to the supporting plate, of the supporting plate.
Optimally, the fixing device also comprises a screw which is arranged on the supporting plate in a penetrating way and is connected with the fixing plate and a reinforcing rib which is welded between the vertical plate and the second transverse plate.
Preferably, the first transverse plate and the second transverse plate are arranged in parallel.
Preferably, the fixing plates move in the same horizontal plane.
Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage: the utility model discloses battery capability test fixed bolster fixes not unidimensional battery through the fixed plate that removes, fixes the connecting wire on the clip, because the articulated effect of connecting plate and second diaphragm, can guarantee that the oblique angle of utmost point ear does not change, ensures that the test result is accurate, guarantees not take place the contact between electric core utmost point ear and the electric core utmost point ear for the space of the environment case of test use can be used effectively, saves space.

Fig. 1 is a schematic structural view of the present invention;
description of reference numerals:
1. a first transverse plate; 2. a vertical plate; 3. a second transverse plate; 4. a connecting plate; 5. reinforcing ribs; 6. a clip; 7. a support plate; 8. a fixing plate; 9. and (4) screws.
Detailed Description
The invention will be further described with reference to examples of embodiments shown in the drawings.
As shown in fig. 1, the utility model discloses battery capability test fixed bolster is used in monomer electricity core testing process usually, is used for fixed battery, and it mainly includes first diaphragm 1, riser 2, second diaphragm 3, connecting plate 4, stiffening rib 5, clip 6, backup pad 7, fixed plate 8 and screw 9 etc..
Wherein, riser 2 is fixed on first diaphragm 1 (riser 2 is perpendicular with first diaphragm 1, and accessible welded mode realizes fixedly). The second horizontal plate 3 is fixed at one end of the vertical plate 2 far from the first horizontal plate 1 (in this embodiment, the second horizontal plate 3 is parallel to the first horizontal plate 1, and the length of the second horizontal plate 3 is less than that of the first horizontal plate 1). The connecting plate 4 is hinged at one end of the second transverse plate 3 far away from the vertical plate 2 (the connecting plate 4 can rotate at the end part of the second transverse plate 3).
The reinforcing rib 5 is welded between the vertical plate 2 and the second transverse plate 3 and used for improving the strength of the whole structure. The clip 6 is arranged on the connecting plate 4 (the clip 6 is used for fixing the equipment connecting line). The support plate 7 has two pieces which are fixed on the first transverse plate 1 at intervals (the fixing can be realized by welding). The screw 9 is arranged on the supporting plate 7 in a penetrating mode and can be screwed on the supporting plate 7 to move, the fixing plates 8 are arranged on one side, opposite to the two supporting plates 7, of each supporting plate 7 and are fixed with the end portions of the screw rods 9 (the fixing plates 8 are used for fixing batteries, and along with the movement of the screw 9 on the supporting plates 7, the fixing plates 8 can move synchronously, so that batteries with different sizes can be fixed, and the battery fixing device is wide in application range.
Further, the fixing plate 8 moves in the same horizontal plane, which facilitates the fixing of the battery.
The utility model discloses battery performance test fixed bolster passes through adjusting screw 9 position on backup pad 7 to change the distance between fixed plate 8 and fix the not battery of unidimensional, battery tab has kept an initial oblique angle this moment, fixes the connecting wire on clip 6 and links to each other with battery tab, through the articulated effect of connecting plate 4 and second diaphragm 3, can guarantee not to take place the displacement between electric core tab and the connecting wire, avoids the condition such as utmost point ear atress or atress inequality to take place; the battery cell pole lug and the battery cell pole lug are guaranteed not to be in contact with each other, so that the space of the environment box used for testing can be effectively used, and the space is saved.
