Laser welding wire-feeding adjusting device

Abstract

The invention relates to a laser welding wire-feeding adjusting device. The adjusting device comprises a wire-feeding guide pipe, a fixing connecting component which is connected with the wire-feedingguide pipe and used for controlling a wire-feeding direction to form a preset included angle with a laser irradiation direction, and a three-dimensional adjustable mechanism which is connected with the fixing connecting component and used for realizing adjustment of the wire-feeding guide pipe in XYZ directions. One end of the wire-feeding guide pipe is provided with a wire-feeding nozzle. The fixing connecting component is provided with a protecting gas inlet. The wire-feeding nozzle is provided with an air-blowing nozzle for blowing a protecting gas in the wire-feeding guide pipe. The fixing connecting component and the wire-feeding guide pipe are driven to be adjusted together in the XYZ directions through the three-dimensional adjustable mechanism. The fixing connecting component is provided with the protecting gas inlet, and the wire-feeding nozzle is provided with the air-blowing nozzle, so the three-dimensional wire-feeding adjustment is realized, and applicability of the wire-feeding device is improved. Coaxial transmission of a welding wire and the welding protecting gas is realized, a welding joint is effectively protected, and air cooling can be also performed on a headof the wire-feeding guide pipe and a wire-feeding nozzle part, so laser welding quality is ensured.

Description

technical field [0001] The invention relates to the technical field of laser welding, in particular to a laser welding wire feeding adjustment device. Background technique [0002] Laser welding needs to automatically and synchronously transmit the welding wire during welding, so it is necessary to increase the welding wire feeder device. Usually the welding wire feeder device is relatively large in size and heavy in weight, and cannot be directly installed on the laser welding head or within half a meter nearby, so the welding wire can only be sent from the wire feeder device to the welding head through the conduit . In general, the welding area has a certain range, and the existing wire feeding device usually cannot adjust the wire feeding to different positions within the welding area, and the applicability of the device is poor; and the shielding gas and the welding wire cannot be fed simultaneously Shaft transmission, the external side blowing mechanism is easy to int...

Usually the welding wire feeder device is relatively large in size and heavy in weight, and cannot be directly installed on the laser welding head or within half a meter nearby, so the welding wire can only be sent from the wire feeder device to the welding head through the conduit

In general, the welding area has a certain range, and the existing wire feeding device usually cannot adjust the wire feeding to different positions within the welding area, and the applicability of the device is poor; and the shielding gas and the welding wire cannot be fed simultaneously Shaft transmission, the external side blowing mechanism is easy to interfere, which limits the reachable range of welding, and the wire feeding part cannot be cooled by air, which directly affects the quality of laser welding, and it is difficult to meet the requirements of laser welding in modern production
