PURPOSE:To assemble a battery mainframe under almost the best conditions by finding the minimum fastening force on bolts from test pieces and applying necessary face pressure, lib area and disc spring constants as factors thereto. CONSTITUTION:Test pieces which are made up of the same material as separator plates 2 have and test pieces which are made up of the same material as middle electrodes have and arranged between the preceding test pieces are each fastened with fastening bolts. After libs which are protruded on both faces of the center test piece are adhered to the faces of the test pieces on both sides for assembly until they are thrusted and deformed, 1-atmospheric- pressure air is introduced from a pressure source through a valve, a pressure gage and a connection jig inward of the test pieces on both sides and in the meantime its pressure change is checked. The tension of the bolts at the time when no pressure change occurs is measured. Next, during assembling a battery mainframe, the middle electrode and the separator 2 are fastened with the bolts in the way of applying the same tension to the bolts at positions A-H, K-Q. |
