When the vertical transfer screw 27 is rotated, the sliding block 30 screwed to the vertical transfer screw 27 is raised or lowered, the head 51 is a tilting groove 42 of the tilting block (40) The hinge pin 50 located in the lift. At this time, the head portion 51 of the hinge pin 50 is raised and lowered in contact with the upper and lower surfaces of the guide groove 63 of the guide plate 61.

When the hinge pin 50 is raised or lowered as described above, the guide plate 61 is angularly moved around the hinge axis 71 of the hinge block 70, and the tilting guide integrally formed with the guide plate 70 ( 60 is rotated about the hinge axis (71). At this time, the hinge block 71 rotates by the hinge block 70 fixedly coupled to the tilting guide 60.

As the hinge shaft 71 rotates as described above, the torch clamp holder 80 coupled to the end of the hinge shaft 71 is angularly moved around the hinge shaft 71, and the torch clamp holder 80 is formed. The torch clamp 90 coupled to the two clamping holes 82 is angularly moved.

Thus, the up and down reciprocating actuation force of the sliding block 30 and the tilting block 40 and the hinge pin 50 is angularly transformed by the tilting guide 60 so that the torch clamp 90 is angularly moved, thereby the torch clamp 90 It is possible to adjust the welding angle of the welding torch (3) mounted on the), and to adjust the vertical position of the end of the nozzle portion of the welding torch 3 at the same time, the welding torch (3) mounted on the torch clamp 90 It will be able to accurately position the weld.

By repeating the front, rear, up and down position and the welding angle adjustment process in the forward and backward position and the up and down position and the welding angle adjustment process of the welding torch holding device, the welding torch 3 can be more accurately positioned at the welding portion.

Although the welding torch holding apparatus of the automatic transfer welding apparatus according to the embodiment of the present invention as described above has been shown in accordance with the above description and drawings, this is only an example and is not limited to the scope of the technical idea of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made therein.
