Problems solved by technology
[0003] In the related technology, a fixing groove is provided on a tooling, and the cover plate is fixed through the fixing groove, but due to the size limitation of the fixing groove, for different battery types of cover plates, the tooling needs to be replaced according to different widths, and the process time Long, high cost, and low clamping stability. During the tensile test process, it is easy to cause small movement of the cover plate, which affects the accuracy of experimental data.

The invention relates to the technical field of batteries, and provides a clamping mechanism and a tension testing device for a battery cover plate. The clamping mechanism comprises a base, a first positioning member, a second positioning piece and a driving assembly, wherein the first positioning piece and the second positioning piece can form a clamping space for clamping a workpiece; the driving assembly comprises a pull rod piece, a first connecting rod piece and a limiting piece, the pull rod piece is arranged on the base in a penetrating mode, and one end of the pull rod piece is hinged to one end of the first connecting rod piece; and the pull rod piece is movably arranged so that the first connecting rod piece can drive the first positioning piece to move in the direction close to or away from the second positioning piece, and when the first positioning piece and the second positioning piece clamp a workpiece, the limiting piece can make limiting contact with the base so that the pull rod piece can be prevented from moving. When the first positioning piece and the second positioning piece clamp the workpiece, the limiting piece is in limiting contact with the base, so that the problem that the workpiece is separated from the first positioning piece and the second positioning piece is avoided.
Description
technical field [0001] The invention relates to the technical field of batteries, in particular to a clamping mechanism and a tensile testing device for a battery cover. Background technique [0002] The cover plate is one of the components of the battery cell structure assembly, and the poles and pins of the cover plate are welded. In order to evaluate the tensile strength of the soldered pins, a tensile test machine was used to perform a tensile test (fix the cover, pull the pins). [0003] In the related technology, a fixing groove is provided on a tooling, and the cover plate is fixed through the fixing groove. However, due to the size limitation of the fixing groove, for different battery types of cover plates, the tooling needs to be replaced according to different widths, and the process time Long, high cost, and low clamping stability. During the tensile test process, it is easy to cause small movements of the cover plate, which affects the accuracy of experimental ...
