Abstract
The invention relates to the field of tailored blank laser welding, in particular to a weld joint control device of tailored blank laser welding. The weld joint control device of tailored blank laser welding comprises a laser welding head and is characterized in that a grinding idler wheel located on the center of the end portion of a workpiece to be welded, a motor or a magnetic force part connected with the grinding idler wheel and a sensor arranged on a weld joint of tailored blank welding are included, the sensor detects the size of the weld joint and transmits weld joint size signals to a controller, and the controller drives the motor or the magnetic force part to run. According to the weld joint control device of tailored blank laser welding, the laser welding head carries out tailored blank welding on the weld joint, the weld joint becomes larger and larger in the tailored blank welding process, the sensor detects that the weld joint becomes larger and larger and transmits the signals to the controller, the controller controls the motor to drive the idler wheel to move, or the controller controls the magnetic force part to have magnetic force and facilitate the movement of the grinding idler wheel through the magnetic force. Further, the central grinding idler wheel extends the edge of the thick workpiece to be welded through grinding, the size of the weld joint is reduced, and welding quality is improved.
Description
Technical field
The present invention relates to the laser assembly solder field, relate in particular to a kind of laser tailor-welded weld control device.
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 with the steel plate of two or multiple different-thickness or unlike material by laser to being welded into a block plate, then carry out whole punch forming.Welding is carried out in laser welding system between the welding weld seam, in the welding process, weld seam becomes large, affects welding quality.
Summary of the invention
The object of the invention is to overcome the problems referred to above, a kind of good laser tailor-welded weld control device of welding quality that makes is provided.
For achieving the above object, the technical solution adopted in the present invention is: the laser tailor-welded weld control device, comprise laser welding system, it is characterized in that: also comprise rolling-compaction roller, the motor that is connected with rolling-compaction roller or the magnetic force section that is positioned at workpiece end to welding central authorities, the sensor that is arranged at the welding weld seam, sensor detects welding weld seam size and the weld seam high low signal is passed to controller, by controller drive motors or the action of magnetic force section.
Aforesaid laser tailor-welded weld control device, also comprise be used to the operating desk of placing workpiece to welding.
Aforesaid laser tailor-welded weld control device, described operating desk is the angle mesa structure, weld seam is positioned at angle.
Aforesaid laser tailor-welded weld control device, described motor or magnetic force section are positioned at the outside of the edge of work to welding.
Aforesaid laser tailor-welded weld control device, described magnetic force section is connected with rolling-compaction roller magnetic, described motor and rolling-compaction roller electrical connection.
