Abstract

The utility model relates to a laser focus-position following control welding head for laser processing such as laser welding, heating disposal of laser surface, surface coagulation-dissolving reinforcement, etc. A compressed spring is arranged between a connecting flange and a transitional flange; the transitional flange connects the compressed spring with a laser head; the lower part of the laser head is connected with a thread of the nozzle of a welding head; a drag cover on middle part of the welding nozzle is connected by the thread. The upper part of the connecting sleeve is added with a drag cover plate; the lower part of the connecting sleeve is connected with two hubs by screw thread; each hub is provided with a guide supporting wheel by a pin shaft; two supporting wheels are symmetrically distributed by an axis line of the laser welding head, namely, a central line of the light beam, ensuring the laser to pass in the middle of the supporting wheel. The utility model combines a welding gas protection drag cover with the welding head, stably controls the distance between the defocusing amount and the drag cover and the workpiece with the guide supporting wheel; especially when the long welding seam is welded, the utility model implements the compensation to the change of the distance between the defocusing amount and the drag cover and the welding workpiece caused in the welding processed by the plate thickness or deformation, etc. of the welding seam.

Description

Focal position of laser servo-actuated control plumb joint
Technical field:
The utility model relates to a kind of laser weld that is used for, and plumb joint is controlled in the molten focal position of laser servo-actuated of coagulating Laser Processings such as reinforcements of laser surface heat treatment, surface.
Background technology:
In laser welding processes; the technological factor that influences welding quality mainly contains laser power, speed of welding, defocusing amount, gas shield etc.; therefore for certain material, not only to reasonably select these technological parameters, and should guarantee the stability of these technological parameters.Mostly the defocusing amount of laser welding processes is chosen in advance at present, seldom it is stablized control, and the distortion of the fluctuation of material thickness of slab, joint all will influence defocusing amount inevitably in the welding process, thereby have influence on the quality of weld seam.Moreover widely used Laser Welding gas shield device; mostly be to drag cover and laser weld to be connected as a single entity; or employing is threaded; or adopt chuck to connect; this connected mode can prevent the appearance of weld porosity, still, if drag the distance between cover and workpiece to change in the welding process because of the fluctuation of material thickness of slab, the factors such as distortion of joint; also can produce and disturb the welding of especially long weld seam the protection effect.Because present defocusing amount and drag the distance between cover and workpiece to be mostly to set before the weldering, the workpiece that error is arranged for long weld seam, apparent height, owing to drag the variation of the distance between cover and the workpiece not control in the welding process, cause the instability of defocusing amount, thereby influence the quality of weld seam.
Summary of the invention:
The purpose of this utility model is that a kind of focal position of laser servo-actuated control plumb joint that can control defocusing amount and drag the distance between cover and workpiece is provided.Technical solution of the present utility model is, compression spring 2 places between adpting flange 1 and the counter flange 3, and counter flange 3 will compress spring 2 and be connected with laser head 4, and laser head 4 belows are connected with plumb joint nozzle 8, and welding tip 8 middle parts are covered 5 and are threaded with dragging.The top of adapter sleeve 6 installs additional drags cover cap plate 7, the below of adapter sleeve 6 two wheel hubs 10 that are threaded utilize pivot pin to adorn the axis of a guiding support wheel 9, two support wheels 9 with laser welding system on each wheel hub, be that the beam center line is symmetrically distributed, laser is passed through in the middle of support wheel 9.The utility model is on the basis of existing laser welding system; gas shiled be will weld and cover and plumb joint combination dragged; controlled defocusing amount and dragged distance between cover and workpiece with the guiding support wheel is stable; particularly when the welding of long weld seam; realize the compensation that welding process defocusing amount that butt welded seam causes because of reasons such as thickness of slab or distortion and the variation of dragging the distance between cover and workpiece are carried out, reached the stable control of two parameters.The utility model adopts mechanical type to regulate, and is simple in structure, can realize Synchronization Control.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 drags cover and support wheel cutaway view for the utility model.
The specific embodiment:
Adpting flange 1 upper end is connected with equipment such as Digit Control Machine Tool or manipulators, realizes the locus adjusting of laser welding system 4 to utilize other automaton; The lower end is connected with compression spring 2, and the lower end and the counter flange 3 of compression spring 2 join, and pretension is compressed spring 2 mechanism modules to counter flange 3 and laser welding system 4 connects.Drag cover 5 to be threaded with laser welding system nozzle 8, laser welding system nozzle 8 is connected 4 with laser welding system and is threaded.Drag the relative position of cover 5 and plumb joint 4 to fix.Drag the cover 5 in, the top of adapter sleeve 6 install additional drag cover cap plate 7, the below of adapter sleeve 6 be threaded two row wheel hubs 10, utilize pivot pin to adorn a guiding support wheel 9 on each wheel hub, two support wheels 9 are with the axis of laser welding system, and promptly the beam center line is symmetrically distributed, and laser is passed through in the middle of support wheel 9.Drag two guiding support wheels 9 on the cover 5 to contact with workpiece, when workpiece does not change along thickness direction, utilize the pretightning force effect of pretension compression spring 2 mechanisms, defocusing amount and drag the cover 5 and workpiece between distance can not change, if workpiece changes along thickness direction, guiding support wheel 9 utilizes the deformability of pretension compression spring 4 mechanisms to rise or descend, to guarantee defocusing amount and to drag stable distance between cover 5 and workpiece on predetermined value.
