Automatic welding device for lower oil pans

Abstract

The invention discloses an automatic welding device for lower oil pans. The device comprises an intermediate frequency energy storing welder, a feeding conveyor line, a discharging conveyor line, a nut feeding assembly, a robot, a robot electric cabinet, a control cabinet and a nut locating assembly, wherein the feeding conveyor line is used for conveying the oil pans to the position of the intermediate frequency energy storing welder; the robot is used for transferring the oil pans to the oil pan welding part of the intermediate frequency energy storing welder from the feeding conveyor line and is also used for transferring welded finished products to the discharging conveyor line, and the discharging conveyor line is used for outputting the finished products; the nut feeding assembly is arranged at one side of the intermediate frequency energy storing welder and used for conveying nuts to the position of the intermediate frequency energy storing welder; the nut locating assembly is arranged between the intermediate frequency energy storing welder and the nut feeding assembly and used for transferring the nuts from the nut feeding assembly to the oil pan welding part; and the intermediate frequency energy storing welder is connected with the control cabinet, and the intermediate frequency energy storing welder discharges electricity and finishes the welding of the oil pans and the nuts under the control of the control cabinet.

Description

technical field [0001] The invention relates to an automatic welding device for a lower oil pan, in particular to an automatic welding device for intermediate frequency energy storage resistance projection welding for a lower oil pan. Background technique [0002] The oil pan is one of the important parts of the automobile engine system, and the sealing ability of the oil pan has an extremely important influence on the engine. The oil drain part of the oil pan is welded by the shell and the nut, and is assembled with the sealing bolt as the key of oil storage and oil discharge. In the prior art, the welding of the shell and the nut generally adopts the resistance projection welding process. The above-mentioned process is still completed by workers manually with the equipment. In the process of manual coordination with the equipment, it is necessary to manually position the shell and nuts for production. In this case, not only the labor force on the production line increases,...
