Fig. 2, the second embodiment of the present invention.
Detailed description of the invention
As shown in Figure 1, a kind of welding mechanism modified node method of automatic welding machine, comprise one and to be positioned on work slide rail 1 and can along the work slide block 2 of work slide rail 1 movement, the movement of work slide block 2 on work slide rail 1 drives 11 by operation power source.
Rear on work slide block 2 is provided with a jaws just to the afterbody chuck 3 in front, and afterbody chuck 3 is by can the fixture block up and down 31,32 of folding form in the present embodiment, forms the gap of workpiece turnover when upper and lower fixture block 31,32 points is opened between.Also other clamp structures can be adopted in practice, as long as can ensure that workpiece 6 can clamp in the smooth charging of level.
Front on work slide block 2 is provided with soldering apparatus 4, and soldering apparatus 4 is made up of ceramic rod 41 and high frequency circle 42, and ceramic rod 41, high frequency circle 42 are positioned on same axis with described afterbody chuck 3.
At this, above ceramic rod 41 can work the guide rail slide anteroposterior on slide block 2 relatively.In the present embodiment, ceramic rod 41 is arranged on positioning seat 411, and positioning seat 411 is installed on the fromer rail 21 on work slide block 2, and whole positioning seat 411 can relatively move back and forth before and after fromer rail 21 under the driving of front reciprocating motion power source 412.And afterbody chuck 3 is positioned on mount pad 33, mount pad 33 is installed on the rear rail 22 on work slide block 2, in practice according to the position of length adjustment mount pad 33 on rear rail 22 of actual processing work 6, and locks with screw 331 after adjusting to the right place.
About one liftable middle part chuck 5 is provided with between described afterbody chuck 3 and soldering apparatus 4, middle part chuck 5 is by base of the carrier head 51 and to be positioned on base of the carrier head and can the left and right fixture block 52 of folding to form, the bottom of base of the carrier head 51 is connected with a chuck reciprocating lifting mechanism 53, in the present embodiment, chuck reciprocating lifting mechanism 53 is directly positioned on work slide block 2.At this, above left and right fixture block 52 be arranged in the side 521 at jaws place right-angle surface or arc surface or one for right-angle surface one be arc surface, two sides 521 are right-angle surface in the present embodiment.
Work in-process, the elemental height of middle part chuck 5 is lower than the motion track of transverse shifting chuck, first clamped by described afterbody chuck 3 when the workpiece transfer of populated alloy sheet is come by transverse shifting chuck, afterwards middle part chuck 5 rise and the neck clamping workpiece 6 to correct the centering of workpiece, workpiece 6 is made to be positioned on same axis all the time with soldering apparatus 4 in welding process, to ensure the accurately precisely welding of alloy sheet 61.Move alloy sheet 61 top held in workpiece 6 otch afterwards in ceramic rod 41, then whole work slide block 2 moves and the position at alloy sheet 61 place is moved to high frequency circle 42 and carries out welding operation.
To sum up, the present invention adds middle part chuck 5 structure on existing structure basis, in welding, pass through the common positioning action of middle part chuck 5 and afterbody chuck 3, can ensure that bit body welding phase is to effective centering of soldering apparatus 4, promotes the welding quality of bit body and alloy sheet.
In addition, occur for solving the situation having a strong impact on welding quality in welding on the downside of copper liquid deflection workpiece 6 otch, as shown in Figure 2, ceramic rod 41 of the present invention is arranged on positioning seat 411 by a bearing 413, can freely rotate by relative positioning seat 411 to make whole ceramic rod 41.And afterbody chuck 3 is positioned on mount pad 33 by a chuck rotating shaft 34, the afterbody of chuck rotating shaft 34 directly connects drive motors 35 or connects drive motors 35 by belt gear 351, adopts the latter in the present embodiment.Simultaneously for ensureing that workpiece can normal rotation, in middle part chuck 5, the medial surface of left and right fixture block 52 is all arranged to arcwall face, still leaves certain small―gap suture during left and right fixture block clamping simultaneously between itself and the neck of workpiece 6.
In welding process, whole afterbody chuck 3 can rotate under the drive of drive motors 35, and in whole welding process, this rotational angle should not be less than 180 °.And Timing Belt is started building by the rotation of afterbody chuck 3, part 6 rotates together with ceramic rod 41, this rotating welding mode makes workpiece 6 welding position be heated evenly on the one hand, another is convenient to ensure that the copper water of copper bar thawing in otch is evenly distributed on the both sides up and down of otch, copper water is avoided to be partial to the generation of one-sided phenomenon, effectively can ensure the validity that alloy sheet 61 welds, promote the bonding strength of alloy sheet 61 and workpiece 6, ensure welding quality.
The above, it is only better embodiment of the present invention, not any pro forma restriction is done to invention, every according to know-why of the present invention to any simple modification made for any of the above embodiments, equivalent variations or modification, still belong in the scope of technical solution of the present invention.
