Description

A kind of lithium battery pull force calculation fixture
Technical field
The utility model relates to detection field of fixtures, particularly relates to a kind of lithium battery pull force calculation fixture.
Background technology
In lithium battery welding technology, nickel sheet and battery need be carried out welding as wherein one of of paramount importance link, its welding quality has a significant impact final products performance, if weld strength not easily ruptures, cause loose contact and affect normal battery operation, therefore in order to ensure product stability and security, effectively need detect welding battery intensity, checking the welding pulling force of its nickel sheet whether to meet technological requirement.
Usually tension tester is utilized to detect the resistance to pulling force of nickel strap, in existing technology, manually nickel strap is loaded in two pull force calculation fixture blocks, fixture block dominated by hand, then tighten the screw of connection two pull force calculation fixture blocks, then carry out pull force calculation by tension tester.Existing fixture block dominated by hand, tighten the screw of connection two pull force calculation fixture blocks to detect nickel strap welding pulling force, inefficiency, and when detecting, battery positive and negative electrode pulling force detects together, accuracy of detection is not accurate enough.
Utility model content
Based on this, be necessary for prior art problem, a kind of lithium battery pull force calculation fixture is provided, this detection fixture convenient operation and raising measuring accuracy.
For solving prior art problem, the utility model discloses a kind of lithium battery pull force calculation fixture, described fixture is made up of bottom plate apparatus and stationary fixture, bottom plate apparatus comprises a base plate, base plate is provided with the both sides location-plate of parallel placement, and form interspersed position between the location-plate of both sides, the junction between location-plate one end, side and base plate is provided with spacing, form locating groove, one end base plate being positioned at locating groove is provided with chute;
Stationary fixture includes two fixed heads, and two fixed head sides are connected by loose-leaf, and be provided with clamping position between two fixed heads, two fixed head one end are provided with hangers, and the other end is provided with groove.
The beneficial effects of the utility model are: a kind of lithium battery pull force calculation of the utility model fixture is arranged by bottom plate apparatus being fixed on solid pull force calculation instrument, and design battery stationary fixture, laterally longitudinally battery can be fixed on base plate and carry out tensile test, only battery stationary fixture need be positioned over base plate fixture during operation to fix, battery one end nickel sheet is fixed on detection fixture block, after detecting OK, then other end nickel sheet weld strength is detected.Substantially increase detection efficiency and measuring accuracy.
Accompanying drawing explanation
The structural representation of Fig. 1 to be the utility model be bottom plate apparatus;
The structural representation of Fig. 2 to be the utility model be stationary fixture;
Fig. 3 is the schematic diagram of test battery;
When Fig. 4 is testing longitudinal, bottom plate apparatus and stationary fixture combinationally use demonstration graph;
When Fig. 5 is transverse test, bottom plate apparatus and stationary fixture combinationally use demonstration graph.
Embodiment
For feature of the present utility model, technological means and the specific purposes reached, function can be understood further, below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in the figure, the utility model discloses a kind of lithium battery pull force calculation fixture, described fixture is made up of bottom plate apparatus and stationary fixture, bottom plate apparatus comprises a base plate 1, base plate 1 is provided with the both sides location-plate 2 of parallel placement, form the junction of interting between location-plate 2 one end, side, position 21 and base plate 1 between both sides location-plate 2 and be provided with locating groove 3, one end base plate 1 being positioned at locating groove 3 is provided with chute 11, and the effect of chute 11 is nickel sheet avoiding hollow grooves;
Stationary fixture is included two fixed head 4, two fixed head 4 sides and is connected by loose-leaf 5, and be provided with clamping fixed head 4 one end, position 6, two between two fixed heads 4 and be provided with hangers 41, the other end is provided with groove 7, and when the effect of groove 7 is transverse tests, nickel sheet is stretched out from groove 7.
During operation, first open two fixed heads 4, battery 8 is placed in the clamping position 6 between two fixed heads 4, then relatively close up two fixed heads 4 and clamp battery 8, then the stationary fixture that battery 8 is housed is fixed on bottom plate apparatus, anode end nickel sheet is fixed on tension tester to detect in fixture block, carry out pull force calculation, after positive pole nickel sheet tensile test, anticathode is tested again again.
The stationary fixture that battery is housed can longitudinally or laterally be fixed on bottom plate apparatus respectively, longitudinally, laterally can detect battery nickel sheets weld strength.
During testing longitudinal, be provided with one end of hangers 41 down in stationary fixture, hangers 41 is inserted in locating groove 3 along base plate 1, now stationary fixture and the relatively stable location of bottom plate apparatus.
During transverse test, the parallel insertion in one end that stationary fixture is provided with groove 7 interts in position 21, until side location-plate 2 withstands hangers 41.
This test fixture compared to existing technology, namely can make battery positive and negative electrode carry out pull force calculation simultaneously, more crucially ensure that accuracy of detection.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
