Automatic assembling, welding and detecting all-in-one machine for automobile injection pump

The invention relates to an automobile injection pump automatic assembling, welding and detecting all-in-one machine which comprises a machine table, a circulating line is arranged on the machine table, and a plurality of positioning carriers are fixedly connected to a conveying belt of the circulating line. A lower shell feeding mechanism, a nozzle feeding mechanism, a double-station welding module, a lower shell cover feeding mechanism, a steel belt punching machine, an upper shell feeding mechanism, an upper shell welding mechanism, an upper shell cover feeding mechanism, an upper shell cover welding mechanism, a sleeve feeding mechanism, a sleeve welding module and a sealing ring assembling mechanism are sequentially arranged on the machine table around a circulation line. The device comprises an air tightness flow detection mechanism, a laser marking mechanism and a discharging mechanism. The laser welding machine has the beneficial effects that the laser welding machine can adapt to integrated assembly
