The limit lever 56 is pulled rightward so that the limit bevel gear 55 moves rightward to be out of engagement with the positioning bevel gear 59 and the ring bevel gear 72 against the elastic force of the limit spring 57.

At this time, the position of the angle adjusting box 40 is adjusted so that the lead work piece approaches the position to be welded.

In the process of adjusting the angle adjusting box 40, if the positioning rotating wheel 50 rotates forwards, the friction wheel 610 rotates backwards, thereby driving the follower worm shaft 67 to rotate backwards, thereby driving the follower worm 68 to rotate backwards, thereby driving the follower worm wheel 69 to rotate forwards, thereby driving the follower worm wheel shaft 66 to rotate forwards, thereby driving the bevel gear sleeve 65 to rotate forwards, thereby driving the drive bevel gear 64 to rotate forwards, thereby driving the driven bevel gear 62 to rotate backwards, thereby driving the angle adjusting box 40 to rotate backwards, if the positioning rotating wheel 50 rotates backwards, the angle adjusting box 40 rotates forwards, and the rotation angle of the angle adjusting box 40 is consistent with the rotation angle of the positioning rotating wheel 50, thereby realizing that in the rotation process of the positioning rotating wheel 50, the angle adjusting box 40 can always keep an initial state, namely, a state parallel to the ground is kept.

At the same time, the positioning slider 60 slides in the positioning slider cavity 51, thereby realizing that the angle adjusting box 40 can move to any position in a circular plane with the center of the positioning runner 50 as the center and the length of the positioning slider cavity 51 as the diameter.

During the sliding process of the positioning slider 60, the positioning slider 60 drives the screw 63 to rotate, so that the positioning bevel gear 59 rotates.

Due to the spline fit between the limiting pull rod 56 and the positioning rotating wheel 50, the limiting pull rod 56 cannot rotate, and the limiting bevel gear 55 cannot rotate.

If the position of the angle adjusting box 40 is adjusted, the limit pull rod 56 is released, so that the limit bevel gear 55 moves leftwards under the elastic force of the limit spring 57 to be meshed with the positioning bevel gear 59 and the annular bevel gear 72, the positioning bevel gear 59 cannot rotate, the screw 63 cannot rotate, and the positioning slide block 60 cannot freely slide.

Meanwhile, the limit bevel gear 55 is meshed with the annular bevel gear 72, so that the positioning rotating wheel 50 cannot rotate freely, and the positioning effect of the angle adjusting box 40 is achieved.

At this time, according to the shape of the composite copper bar conductive layer, the adjusting turntable 41 is rotated, so that the worm shaft 42 is rotated to drive the worm 46 to rotate, further the worm wheel 44 is rotated to drive the worm wheel shaft 45 to rotate, further the clamping seat 30 is rotated, and then the lead wire workpiece is driven to rotate to abut against the composite copper bar conductive layer.

And electrifying the composite copper bar and the lead workpiece, so that the composite copper bar and the lead workpiece generate heat, and welding the composite copper bar and the lead workpiece together through brazing.

At this moment, the motor 28 is reversed, so that the piston 22 moves upwards to the initial position, and the motor 28 is closed, so that the air pressure in the pressure cavity 23 is recovered to be normal, and the composite copper bar can be taken down from the copper bar fixing seat 20.

And pulling the clamping plate pull rod 34 upwards to take the welded lead workpiece out of the clamping cavity 35, so that one-time welding of the composite copper bar is completed.

It will be apparent to those skilled in the art that various modifications may be made to the above embodiments without departing from the general spirit and concept of the invention. All falling within the scope of protection of the present invention. The protection scheme of the invention is subject to the appended claims.
