Abstract
The utility model discloses a kind of battery core fixtures, comprising: top panel and lower panel；Locating rod connects top panel and lower panel；Clamping component is connect with top panel, and clamping component includes: clamping plate, is arranged above between plate and lower panel；Screw cooperates with top panel；Spring, first end are connect with screw, and second end is connect with clamping plate, solve the problems, such as stationary fixture during battery core stationary fixture power loop test because battery core expansion causes to test pressure and be multiplied to influence cycle performance.
Description
Technical field
The utility model belongs to battery technology field more particularly to a kind of battery core fixture.
Background technique
In the process of implementing the utility model, the inventor finds that the existing technology has at least the following problems:
Power battery core Pack forms battery pack at mould group, and battery core can be expanded in charge and discharge process and be generated certain
Power.For recycling condition of the more preferable simulation assessment battery core in Pack packet, single battery core is in R&D process, loop test
It can be tested under certain chuck force, for stationary fixture, initial setting clamp power is certain value, due to meeting in battery core cyclic process
Expansion, causes the power of stationary fixture that can be doubled and redoubled, influences battery core cycle performance.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of solution stationary fixtures to follow in battery core stationary fixture power
Because battery core expands the battery core fixture for leading to test pressure and being multiplied the problem of influencing cycle performance during ring test.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the utility model is a kind of battery core fixture, comprising:
Top panel and lower panel；
Locating rod connects the top panel and lower panel；
Clamping component is connect with the top panel, and the clamping component includes:
Clamping plate is arranged between the top panel and lower panel；
Screw cooperates with the top panel；
Spring, first end are connect with the screw, and second end is connect with the clamping plate.
A clamping component also is provided on the lower panel.
One clamping component includes four groups of screws and spring, and four groups of screws and spring are separately positioned on four of the clamping plate
On angle.
There are four the locating rod is total, it is separately positioned on four angles of the top panel and lower panel.
A technical solution in above-mentioned technical proposal has the following advantages that or beneficial effect, solves stationary fixture in battery core
Because of the problem of battery core expansion, which causes test pressure to be multiplied, influences cycle performance during stationary fixture power loop test.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the battery core fixture provided in the utility model embodiment；
Fig. 2 is the structural schematic diagram of another structure of battery core fixture；
Label in above-mentioned figure is equal are as follows: 1, top panel, 2, clamping plate, 3, screw, 4, lower panel, 5, locating rod, 6, spring.
Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type embodiment is described in further detail.
Referring to Fig. 1-2, a kind of battery core fixture, comprising:
Top panel and lower panel；
Locating rod connects top panel and lower panel；
Clamping component is connect with top panel, and clamping component includes:
Clamping plate is arranged above between plate and lower panel；
Screw cooperates with top panel；
Spring, first end are connect with screw, and second end is connect with clamping plate.
A clamping component also is provided on lower panel.
One clamping component includes four groups of screws and spring, and four groups of screws and spring are separately positioned on four angles of clamping plate
On.
There are four locating rod is total, it is separately positioned on four angles of top panel and lower panel.
1, unilateral flexible fixture device: including top panel, lower panel, clamping plate, spring, guide rod, positioning column, clamp face plate
It is linked together by locating rod, clamping plate is connected by screw and spring and clamp face plate；
2, unilateral flexible fixture device: including top panel, lower panel, first clamping plate, second clamping plate, spring, guide rod, determine
Position column, clamp face plate are linked together by locating rod, and clamping plate is connected by screw and spring and clamp face plate；
Clamp face plate corresponds to different model battery core with locating rod difference size, and different springs correspond to different pressures test-strips
Part.
According to the variation of battery core expansion rate, for pressure increase maximum value about within 5%, when electric discharge, returns to initial pressure when completely filling
Power state buffers expansive force by spring, keeps test pressure condition constant.
By increasing band spring clip plate, increased pressure, drop are expanded to reduce battery core during the long-term loop test of battery core
Low test battery core pressure change (keeping constant pressure test) improves stationary fixture test pressure and be multiplied making with test
The shortcomings that being deteriorated at battery core cycle performance.Bilateral spring can share out equally expansion deformation pressure, preferably reduction pressure change,
One-sided springs save cost, convenient for laying flat test.
After above-mentioned structure, stationary fixture is solved during battery core stationary fixture power loop test because battery core expands
The problem of causing test pressure to be multiplied influences cycle performance.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, as long as the various unsubstantialities carried out using the method concept and technical solution of the utility model change
Into, or it is not improved the conception and technical scheme of the utility model are directly applied into other occasions, in the utility model
Protection scope within.
