Universal stack banding mold for thermal battery

Abstract

The invention provides a universal stack banding mold for a thermal battery. An upper support plate and a bottom plate are fixedly connected by a plurality of columns, a plurality of location holes are uniformly distributed along several circumferences of different diameters on the opposite surfaces, and several limited posts are fixedly connected through pins along the circumference of the same diameter. A cushion block is a stepped column having an upper end with the diameter being greater than diameter of the lower end, and the end with smaller diameter is installed in a through hole on theupper surface of the cushion block. By installing the cushion blocks with different thicknesses, stack height is regulated. An indenter is mounted in a through hole of the upper support plate, and arectangular through hole is opened in the horizontal direction. When a wedge-shaped sizing block is inserted in the rectangular through hole on the upper surface of the upper support plate, the indenter can be prevented from falling down. When the wedge-shaped sizing block is inserted into the rectangular through hole on the lower surface of the upper support plate, pressure of the indenter can belimited. The universal stack banding mold of the invention is efficient and fast to use and accurate in localization, and has strong practicality and universality.

Description

technical field [0001] The invention belongs to the technical field of thermal battery assembly. Background technique [0002] With the continuous improvement of the thermal battery's ability to resist high overload, the battery stack bundled structure has been widely used in various thermal battery assemblies. Due to the large number of thermal batteries and the different sizes of the single cells that make up the thermal battery, the stack There are many types and quantities of strapping dies. [0003] At present, the commonly used stack binding dies include upper and lower fixing plates, pull rods, positioning sleeves (rods), threaded locking parts, etc. The positioning sleeve and the lower fixing plate slide relative to each other. When the gap is small, the sliding is not free and flexible. It is not accurate enough, and it is locked by threads, which is inconvenient to operate, time-consuming and laborious to lock.

[0003] At present, the commonly used stack binding dies include upper and lower fixing plates, pull rods, positioning sleeves (rods), threaded locking parts, etc. The positioning sleeve and the lower fixing plate slide relative to each other. When the gap is small, the sliding is not free and flexible. It is not accurate enough, and it is locked by thread, which is inconvenient to operate, time-consuming and laborious to lock. One specification of battery pack binding die is only suitable for single batteries of corresponding size, which belongs to special tooling
