Description
Technical field
The utility model relates to technical field of lithium ion more particularly to a kind of lithium ion battery test fixtures.
Background technique
Soft bag lithium ionic cell compared to rectangular cell and cylindrical battery, the advantage is that soft-package battery capacity compared to etc.
High 10-15% of the cylindrical battery of dimensions or so, more rectangular high 5-10% of aluminum-shell battery or so, and the internal resistance of soft-package battery
It is smaller, battery itself loss can be greatly reduced, cycle performance of battery is improved, so that carrying the product battery life of soft-package battery
It is longer, longer course continuation mileage is provided for new-energy automobile.Meanwhile using the soft-package battery of laminated aluminum film, when battery occurs
When short circuit accident, general can occur air-blowing and split, smaller compared to its brisance for rectangular cell and cylindrical battery,
Safety is higher.
However soft-package battery, compared to rectangular aluminum-shell battery and cylindrical battery, battery core does not have harder shell plasticity, holds
Easily deform.After change and high temperature test process, only quadrangle fastens front and back clamping plate by screw and applies existing fixture to battery
Plus-pressure, but this fixture cannot be guaranteed that the pressure for each position for being applied to battery pole piece is uniform, thus influence lithium from
The consistency of contact effect of the sub- battery pole piece different location with diaphragm.
Utility model content
To solve technical problem present in background technique, the utility model proposes a kind of lithium ion battery test fixtures.
The utility model proposes a kind of lithium ion battery test fixture, comprising: first clamping plate, second clamping plate, multiple spiral shells
Nail and multiple gas springs；First clamping plate and second clamping plate are equipped with the multiple threaded holes matched with screw, and multiple threaded holes are equal
Even arrangement, and the threaded hole of first clamping plate and the threaded hole of second clamping plate one-to-one correspondence, first clamping plate and second clamping plate pass through more
A screw thread connection；Multiple gas spring one end are fixedly connected and are evenly arranged with first clamping plate, and the other end is resisted against the second folder
Plate working surface is equipped with battery accommodating space between multiple gas springs and multiple screws.
Preferably, second clamping plate working surface is equipped with pressure sensor, and the back side of second clamping plate working surface is equipped with pressure
Display.
Preferably, the back side of second clamping plate working surface is additionally provided with level meter.
In the utility model, the lithium ion battery test fixture proposed improves each position of battery pole piece and diaphragm
Exposure level consistency, eliminate because fastening screw force unevenness lead to first clamping plate and second clamping plate force unbalance due to
Interference is generated to battery.In addition, this clamp structure is simple, it is easy to operate.
Detailed description of the invention
Fig. 1 be the utility model proposes a kind of lithium ion battery test fixture front view.
Fig. 2 be the utility model proposes a kind of lithium ion battery test fixture rearview.
Fig. 3 be the utility model proposes a kind of lithium ion battery test fixture side view.
Specific embodiment
As shown in Figure 1-3, Fig. 1 be the utility model proposes a kind of lithium ion battery test fixture front view.Fig. 2 is
The utility model proposes a kind of lithium ion battery test fixture rearview.Fig. 3 be the utility model proposes a kind of lithium from
The side view of sub- cell measuring clamp.
Referring to Fig.1-3, the utility model proposes a kind of lithium ion battery test fixture, comprising: first clamping plate 1, second
Clamping plate 2, multiple screws 3 and multiple gas springs 4；First clamping plate 1 and second clamping plate 2 are equipped with the multiple spiral shells matched with screw 3
Pit, multiple threaded holes are evenly arranged, and the threaded hole of first clamping plate 1 and the threaded hole of second clamping plate 2 correspond, the first folder
Plate 1 and second clamping plate 2 are threadedly coupled by multiple screws 3；Multiple 4 one end of gas spring are fixedly connected and uniformly with first clamping plate 1
Arrangement, the other end are resisted against 2 working surface of second clamping plate, and battery is equipped between multiple gas springs 4 and multiple screws 3 and accommodates sky
Between.
In the specific work process of the lithium ion battery test fixture of the present embodiment, first clamping plate 1 is lain in a horizontal plane in into work
Make on table top, the working surface of multiple gas springs 4 and first clamping plate 1 is fixed, then battery is placed in multiple gas springs 4
Between battery accommodating space in, adjust the height of multiple gas springs 4, keep its height consistent, second clamping plate 2 is placed on multiple gas
It on spring 4, is in contact with gas spring 4, screw 3 is threadedly coupled and is consolidated across 1 pair of the two of second clamping plate 2 and first clamping plate
It is fixed.For the dual consideration of battery uniform force and saving cost, the present embodiment is provided with four screws 3 and four gas springs
4。
In the present embodiment, the lithium ion battery test fixture proposed, in use, the consistent gas spring of height
4 two clamping plates apply battery pressure it is relatively uniform, improve the exposure level of battery pole piece each position and diaphragm
Consistency, eliminate because fastening screw 3 exert a force unevenness lead to 2 force unbalance of first clamping plate 1 and second clamping plate due to battery
Generate interference.In addition, this clamp structure is simple, it is easy to operate.
In a specific embodiment, to improve the test batteries of different batches in test by uniform pressure accuracy,
