Air-actuated adjustable welding assembly used for large density battery

Abstract

The invention discloses a pneumatic adjustable welding tooling for a high-density cell, which comprises the following steps: a table welding bracket and a pneumatic hold-down mechanism are arranged above a working table (1); four supporting screws (3) are arranged on the working table(1)by plain cushions (5) and nuts (4), two supporting plates (7) are arranged at the tops of the four supporting screws (3) by bolts (6) and are fixed to form a bracket, and a welding connecting plate is arranged on a supporting plate (7); the pneumatic hold-down mechanism consists of a front baffle plate (9), a pressing plate (11), a cylinder (15) and a cylinder seat (16), wherein, the cylinder (15) is arranged at an side opposite to the front baffle plate (9) by the cylinder seat (16), the cylinder seat (16) is arranged on the working table (1), and a mandrel of the cylinder (15) is matched with the pressing plate (11). As a transitional tooling from the manual welding to the mechanical welding, the pneumatic adjustable welding tooling substantial reduces the labor intensity of staffs, protects the polar plates at two sides, and improves the mechanized production efficiency of cells.

Description

technical field [0001] The invention relates to a special welding tool for large batteries, in particular to a pneumatically adjustable welding tool for large and dense batteries. Background technique [0002] In the production of valve-regulated sealed lead-acid batteries, especially the electrode group welding of large-density lead-acid batteries, for a long time, the method of compressing the electrode group by manpower and then attaching it to the comb plate has been basically used, which causes great harm to personnel. The labor intensity is low, and the work efficiency is low; and it is easy to cause the tabs on both sides to be bent after reaching the comb plate due to the expansion of the pole group, so that the lead paste at the root of the tabs is loose and falls off; at present, lead-acid batteries The industry is emerging a large machine automatic casting welding method, but the one-time investment of this kind of machine equipment is too high, the machine loss a...
