The utility model provides a
lithium battery cap pressure
welding device which comprises a
workbench, moving blocks are connected to the left side and the right side of the bottom in the
workbench in a sliding mode, a driving wheel is fixedly connected to the upper portion of the rear end of the
workbench, and a fixed block is movably connected to the interior of the workbench. According to the pressure
welding device for the
lithium battery cap, by arranging a moving groove, a moving block, a first clamping plate, a driving wheel, a driven wheel, a sliding groove, a sliding block, a fixed block, a second clamping plate and other structures, the moving block achieves transverse movement of the first clamping plate
through transmission of a first double-thread screw, clamping of a
lithium battery is completed, and the driving wheel and the driven wheel transmit power stably through a
transmission belt; a sliding groove, a sliding block and a fixing block are combined and matched with a second double-thread screw, a second clamping plate can clamp the middle of the
lithium battery, the first clamping plate and the second clamping plate are in arc design and provided with an anti-skid pad, the appearance of the
lithium battery is attached,
friction force is enhanced, and the battery is prevented from being damaged and sliding.
