Description of the drawings:

fig. 1 is a schematic structural diagram of the present invention.

The specific implementation mode is as follows:

referring to fig. 1, the present invention specifically adopts the following embodiments: the welding gun comprises a base 1 and a welding gun 12, wherein the number of the base 1 is two, the top end of the base 1 passes through a first screw rod 2, one end of the first screw rod 2 passes through the base 1 and is connected with an output shaft of a first motor, a first thread sleeve 3 is sleeved outside the first screw rod 2, the first thread sleeve 3 is in threaded connection with the first screw rod 2, a fixing plate is welded at the top end of the first thread sleeve 3, the top end of the fixing plate is vertically welded with a side plate 4, the two side plates 4 are fixedly connected through a connecting plate 13, the upper part and the lower part of one end of each side plate 4 are respectively provided with a connecting rod, a second screw rod 5 passes through between the upper connecting rod and the lower connecting rod, one end of the second screw rod 5 passes through the connecting rod and is connected with the output shaft of a second motor, the two second screw rods 5 are connected through a U-shaped plate 9, two threaded holes are formed, one end of a third screw rod 8 penetrates through a U-shaped plate 9 to be connected with an output shaft of a third motor, a second thread sleeve 6 is sleeved outside the third screw rod 8, the second thread sleeve 6 is connected with the third screw rod 8 through threads, a first supporting rod 7 is perpendicularly welded to one end face of the second thread sleeve 6, the end portion of the first supporting rod 7 is hinged to one end of a second supporting rod 11 through a pin shaft, the first supporting rod 7 is connected with the bottom end of the second supporting rod 11 through a driving air cylinder 10, and the end portion of the second supporting rod 11 is fixedly connected with a welding gun 12 through a fixing plate.

When the automatic welding device for machining is used, the base 1 is placed on two sides of a welded piece, the first motors are started, if the thread directions of the two first screw rods 2 are the same, the driving directions of the two first motors are opposite, if the thread directions of the two first screw rods 2 are opposite, the driving directions of the two first motors are the same, namely, the two first thread sleeves 3 are ensured to synchronously advance and retreat, the adjustment of the front and back positions of the welding gun 12 can be realized through the rotation of the two first screw rods 2, so that the welding gun 12 and the welded piece are positioned on the same horizontal line, then, the height of the welding gun 12 is adjusted, the second motors are started, if the thread directions of the two second screw rods 5 are the same, the driving directions of the two second motors are opposite, if the thread directions of the two second screw rods 5 are opposite, the driving directions of the two second motors are the same, namely, the two ends of the U-shaped plate, avoid the both ends action of U template 9 to be inconsistent, two second lead screws 5 adjust welding gun 12 to behind the height more or less, to welding gun 12 about the removal of position, start the third motor, the third motor drives rather than the third lead screw 8 of being connected and rotates, and then with the removal of position about its threaded connection's second thread bush 6 is gone on third lead screw 8, until welding gun 12 remove to by welding piece top can, then recycle second lead screw 5 and adjust welding gun 12's height, make welding gun 12 with by welding piece contact completion weldment work.
