Description
Technical field
The utility model relates to a kind of device for testing tensile force, particularly a kind of device for testing tensile force of lithium ion battery.
Background technology
The weld strength test of the inner ultrasonic soldering of the test battery that uses in the market, resistance welded, laser bonding all uses tautness meter single on the market to measure; Do not have auxiliary frock to measure the fixing of object, when measuring, need staff to carry out subsidiary.When measuring, cause system can produce than big-difference because of different personnel operation.Along with the development in market, the measuring system of this backwardness can not satisfy the requirement of high-end customer, therefore needs a kind of better more accurate weld strength of design to measure frock.The single method subject matter of leaning on tautness meter to measure originally is: 1) object to be measured is fixing inconvenient, loses time.2) measuring system can be because different personnel's operation causes the distribution of data big, and measuring system is unstable.3) can't hang down the welding tensile test of weld strength size battery.The basic reason of the problems referred to above is: 1) this kind measuring system method of testing falls behind, and can not satisfy production requirement.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of device for testing tensile force that improves the stable and easy to operate a kind of lithium ion battery of measuring system is provided.
In order to achieve the above object, the technical scheme of the utility model employing is:
The device for testing tensile force of a kind of lithium ion battery of the utility model; It comprises base plate, in a side of described base plate the workpiece fixed station is installed, and in the centre of described base plate slide rail is installed; First slide block and second slide block that are slidingly matched with it are installed on described slide rail; On described workpiece fixed station, be equipped with workpiece left side fixedly elbow folder and workpiece right side fixedly elbow press from both sides, described first slide block is equipped with tautness meter end workpiece fixed station near the setting of workpiece fixed station on described first slide block; Fixedly elbow folder of tautness meter end workpiece is installed on described tautness meter end workpiece fixed station; On described second slide block, the tautness meter fixed head is installed, on described tautness meter fixed head, tautness meter is installed, an end of described tautness meter and tautness meter end workpiece fixed station are fixedly linked; Described tautness meter fixed head through open above that threaded hole with one through the cooperation that is threaded mutually of the screw rod of Bearing Installation on base plate, described screw rod and slide rail laterally arrange.
The advantage of the utility model is: 1. the weld strength value that can accurately measure measured workpiece.2. the workpiece convenient fixing uses the elbow folder to fix, and pushes and accomplishes the fixing of whole work-piece for three times, need not to carry out screw thread rotation and fixes.3. the apparatus structure idol is simple, and cost is low.

Embodiment
Below in conjunction with specific embodiment the utility model is described in detail.
Device for testing tensile force like a kind of lithium ion battery of the utility model shown in the drawings; It comprises base plate 1; Side at described base plate 1 is equipped with workpiece fixed station 12; In the centre of described base plate slide rail 2 is installed, first slide block 15 and second slide block 14 that are slidingly matched with it is installed on described slide rail, on described workpiece fixed station, be equipped with workpiece left side fixedly elbow folder 11 and workpiece right side fixedly elbow press from both sides 13; Described first slide block is provided with near the workpiece fixed station; Tautness meter end workpiece fixed station 3 is installed on described first slide block, fixedly elbow folder 4 of tautness meter end workpiece is installed on described tautness meter end workpiece fixed station, on described second slide block, tautness meter fixed head 6 is installed; Described tautness meter fixed head is provided with threaded hole 9 and tautness meter 5 is installed; One end of described tautness meter and tautness meter end workpiece fixed station 3 are fixedly linked, the threaded hole on the described tautness meter fixed head with one through the cooperation that is threaded mutually of the screw rod 8 of Bearing Installation on base plate, described screw rod and slide rail laterally arrange.
Be convenient rotation, preferably handwheel 7 be installed at described screw rod.
Among Fig. 1, tautness meter has been installed on the tautness meter fixed head 6 and has been had threaded hole 9, screw rod 8 passes threaded hole, and an end has been installed handwheel 7, and the other end and screw rod fixed block 10 is fixing, in bearing is arranged.
When needing the test piece weld strength, earlier with the workpiece two ends use the left side fixedly elbow folder 11 and workpiece right side fixedly elbow press from both sides 13 and be fixed on workpiece fixed station 12, again with the other end of measured workpiece through tautness meter end workpiece fixedly elbow press from both sides 4 and fix; Open the tautness meter switch, the tautness meter reading that makes zero, CW rotation hand wheel 7; Handwheel 7 drives tautness meter and draws measured workpiece; Throw off until the welding position, record tautness meter reading is accomplished the test of workpiece weld strength.
