The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Referring to Fig. 1-Fig. 3, the utility model embodiment provides a kind of rotary double focus laser processing head, comprise the generating laser (not shown), light pipe (not shown) and focus lamp 1, light pipe mainly is the laser beam 2 that the transmission laser transmitter sends, focus lamp 1 then is the laser beam 2 that generating laser sends to be focused on produce focus 21, light pipe comprises first conduit and second conduit two parts, and between is folded with beam splitter 31, and beam splitter 31 is connected with a drive unit 32, and drive unit 32 can order about beam splitter 31 rotations.The laser beam 2 that beam splitter 31 can send generating laser is focusing on two focuses 21 of back formation through focus lamp 1, can overcome single focus 21 energy transmission defect of insufficient, can be used for the welding than heavy-gauge sheeting, and weld seam 4 is molten wide bigger, be not easy to produce the situation that focus 21 departs from weld seam 4, bifocus 21 can improve the Energy distribution of weld seam 4 both sides flexibly further.Beam splitter 31 is connected with drive unit 31, it can be rotated around rotation A, and the position of bifocus 21 also changes thereupon, if two focuses 21 in the weld seam 4 are drawn a straight line, beam splitter 31 rotates to an angle, and this straight line also can change identical angle, namely when weld seam 4 has the turning, with the beam splitter 31 rotations number of degrees identical with weld seam 4 turnings, bifocal 21 can be welded along weld seam 4 turnings.
Further, the rotation A of beam splitter 31 is vertical with focus lamp 1, and welding quality is improved in weld seam 4 positions of the bifocal 21 vertical welding fittings after laser beam 2 line focus mirrors 1 focus on like this.
Referring to Fig. 1 and Fig. 2, the slewing area of beam splitter 31 is the 0-360 degree particularly.Under the effect of beam splitter 31, the line of bifocal 21 also can rotate in the 0-360 degree, the weld seam 4 that can realize different angles like this welds, when beam splitter 31 rotations 90 are spent, the weldering spot 41 of weld seam 4 both sides also correspondingly rotates 90 degree, namely can realize having the welding of the weld seam 4 at 90 degree turnings.
Certainly, laser beam 2 is not necessarily just propagated in the process of propagating in the same direction, can tilt to be provided with a completely reflecting mirror (not shown) under focus lamp 1, changes the propagation path of laser beam 2, with the weld seam 4 of convenient welding all places.
Particularly, this processing head also comprises pedestal 3, and pedestal 3 has an opening 33, beam splitter 31 be positioned at opening directly over, second conduit runs through opening 33 and first vessel clamp is established beam splitter 31, and drive unit is located on the pedestal 3, processing head has globality, and it is fairly simple that structure also seems.Certainly also can offer opening 33 on the pedestal 3, be connected with the connecting rod (not shown) between beam splitter 31 and the drive unit 32.
Further referring to Fig. 2 and Fig. 3, on pedestal 3, can be provided with an angle sign 34, beam splitter 31 is provided with pointer 311, when beam splitter 31 does not rotate, zero graduation on the pointer 311 orientation angle sign 34, and order about down at drive unit 32, after beam splitter 31 turns an angle, the respective angles of pointer 311 orientation angle sign 34.After determining the angle of weld seam 4, after can regulating beam splitter 31 its pointer 311 being pointed to corresponding angle, can realize the welding of butt welded seam 4, very convenient.
Refer again to Fig. 1, first conduit and also is provided with a collimating mirror 5 in it between beam splitter 31 and generating laser, is used for laser beam 2 is become directional light.Usually the laser beam that sends of generating laser 2 is divergent beams, and through under the effect of collimating mirror 5, divergent beams become collimated light beam, and directionality is better, and energy is more concentrated.
Particularly, beam splitter 31 is prism or lens.Prism and lens can become angled laser beam 2 with collimated laser beam 2, are focused into two focuses 21 behind the line focus mirror 1.Certainly prism in prism, laser beam 2 can become two focuses 21, and is pentaprism etc., and laser beam 2 can become many focuses 21, strengthens welding effect further.
Particularly referring to Fig. 1 and Fig. 4, drive unit 32 comprises actuating unit 321, driving wheel 322 and driven pulley 323, adopt belt 324 to be connected between driven pulley 323 and the driving wheel 322, driven pulley 323 is located between beam splitter 31 and the pedestal 3 and with beam splitter 31 and is fixed, driven pulley 323 hollows, and second conduit therefrom runs through, actuating unit 321 vertically arranges and driving wheel 322 is connected and order about its rotation, and through belt 324 transmissions, and then drive beam splitters 31 by driven pulley 323 and rotate around rotation A.This transmission is more stable, and structure is also more stable, and convenient to the replacing of belt 324.
Refer again to Fig. 3, be provided with adjusting device 325 at a side of belt 324, be used for regulating the elasticity of belt 324.In belt 324 transmissions, belt 324 can not be pine, can not tension, pine is unfavorable for the energy transmission between driving wheel 322 and the driven pulley 323, the tension belt 324 that then weares and teares easily is provided with adjusting device 325 at a side of belt 324, just can realize that then the degree of tightness of belt 324 is suitable.General adjusting device 325 is for being located at the adjustable directive wheel of belt 324 1 sides.
Particularly, actuating unit 321 can be motor, rotary cylinder or rotary magnet, and energy output is more stable, and its moment of torsion is all bigger, and the response time is fast.
