Abstract
The invention relates to the field of laser tailored welding, in particular to a laser cutting and welding device. The laser cutting and welding device comprises a working table for placing a steel plate to be welded; a swinging laser working head; a bearing arranged on the laser working head, wherein the laser working head stays in any point of an arc that takes the center of the bearing as the center of circle and the distance from the focus to the center of the bearing as the radius; and a laser light path device connected with the laser working head, wherein the laser light path device is provided with a laser working head swinging circuit, a laser working head starting working circuit and a laser working head stopping working circuit. The laser cutting and welding device has the advantages that the laser light path device controls the laser working head to move to a special work station to execute corresponding operation, the degree of automation is high, two steel plates to be welded can be respectively cut and subjected to integral butt-welding at one time, and the control on the cutting and butt welding steps is more precise. The assembling surfaces of the two steel plates to be welded after the completion of the cutting operation have same roughness, so that the welding quality and efficiency are improved.
Description
Technical field
The present invention relates to the laser assembly solder field, relate in particular to a kind of cut and welder, the cutting and the welding of two blocks of steel plates to be spliced of this device disposable completion of ability.
Background technology
The laser assembly solder technology is widely used in automobile manufacturing field, especially vehicle body design and manufacturing.Laser assembly solder plate be steel plate with two or many different-thickness or unlike material through laser to being welded into a block plate, carry out whole punch forming then.Because laser assembly solder requires very strict to the fit-up gap and the fitting surface of two fishplate bars to be welded; When the roughness difference of the fitting surface of two fishplate bars to be welded is big; With reducing the intensity of welding quality with the laser assembly solder plate of processing, the laser assembly solder plate easy of crack of processing.For the roughness of the fitting surface that makes two fishplate bars to be welded is identical, can use identical laser head, when the laser work head can be swung, should accomplish the cutting and the butt welding of two steel plates to be welded respectively through setting different stations.The laser work head of considering swing must move to specific station, and after moving to specific station, should carry out corresponding operation, is necessary to be provided with the laser circuit device.
Summary of the invention
The objective of the invention is to overcome the problems referred to above; A kind of novel cut and welder are provided; The cutting respectively and the whole butt welding of two blocks of steel plates to be spliced of this device disposable completion of ability; Laser circuit device control laser work head moves to specific station and carries out corresponding operating, and automaticity is high, and the control of cutting and butt welding operation is more accurate; The fitting surface of two steel plates to be welded had identical roughness after cutting was accomplished, and improved welding quality and welding efficiency.
For realizing above-mentioned purpose, the technical scheme that the present invention adopted is: cut and welder, it is characterized in that, and comprising: the workbench of placing steel plate to be welded; The laser work head that can swing; Be located at the bearing of laser work head, it is the center of circle that the laser work head rests on the bearing centre, be on the arbitrfary point of camber line of radius to the distance of bearing centre with focus; The laser optical path device that is connected with the laser work head, laser optical path device are provided with laser work head wobble circuit, laser work head and open operating circuit, the laser work head circuit that quits work; Be located at the air inlet openings that is used to suck protective gas of laser work head.
Aforesaid cut and welder, the weld seam of described steel plate to be welded are straight line.
Aforesaid cut and welder; Three stop places of described laser work head wobble circuit control laser work head are respectively first cutting work station of cutting first steel plate, second cutting work station of cutting second steel plate, the welding station of welding two steel plates.
Beneficial effect of the present invention is: laser circuit device control laser work head moves to specific station and carries out corresponding operating; Automaticity is high; The cutting respectively and the whole butt welding of two blocks of steel plates to be spliced of the disposable completion of ability, the control of cutting and butt welding operation is more accurate; The fitting surface of two steel plates to be welded had identical roughness after cutting was accomplished, and improved welding quality and welding efficiency.
