A lithium battery cell thickness measuring jig

Abstract

The utility model relates to a kind of lithium battery cell thickness measuring fixture, to solve current manual measuring tool, error is larger, and traditional measuring tool is usually needed to hold down cell in the measuring process, this not only leads to the cell is more troublesome to take and place, also possibly due to improper clamping force leads to the technical problem of cell deformation, including base and vertical board, the surface of vertical board is fixedly connected with two lifting frames, and the upper and lower inner walls of lifting frame are fixedly connected with slide bar, two slide bars are vertically through the front and rear surfaces of lifting plate and are slidably connected with lifting plate, the bottom of lifting plate is fixedly connected with abutting head, the utility model is driven abutting head to move by setting lifting plate between lifting frame, to let abutting head freely abut cell when measuring, avoid the problem that cell deformation can be caused by the clamping of traditional measuring appliance to cell, it is convenient and fast to take and place cell, only need to lift abutting head, without repeatedly releasing clamping, convenience is improved.
