疑を行なうことができないという欠点があった。For example, there is one shown in FIG. This holding device is attached to a revolving body (3) that is rotatably held via a movable frame (swivel drive device 12 at υ) that is movable in front and rear, left and right, and upper f directions, and the welding torch is attached to the revolving body (3). 1 and 4) are always held facing one point. That is, the above-mentioned holding device has a first link (5) with one end supported on the upper part of the hanging part (3a) of the revolving body +31, and one end supported on the lower part of the hanging part (3a). a third link (7) whose one end is pin-connected to the other end of the first link +51 and whose intermediate portion is pin-connected to the intermediate portion of the second link (6); is the second link (
6) The fourth link (8) is pin-connected to the other end, and the other end of the third link (7) and the other end of the fourth link (8) are connected together, and a welding torch +41 is attached. 7'
(A motor that swings the entire link in a vertical plane around the fifth link (9) and one end of the first link (5)
It consists of 1G. And then, the first link (
5) and the second link [6], the third link (7) and the fourth link [6]
The link (8) is the second link (6) and the fifth link (9).
1 are made parallel to each other, and the lengths of the links that are parallel to each other or the lengths of the links are made equal to each other. Therefore, the second link 16
) and the third link (7) form two sets of parallel link mechanisms Iambi. After the welding torch (4) is moved, the tip of the welding torch (4) always faces a certain point regardless of the swing angle. However, since this holding device has two sets of parallel link trowels, the overall size of the device becomes large, and depending on the shape of the welding structure, the large link trowels themselves may get in the way and prevent welding.
It had the disadvantage that it could not be questioned.

Fill is a movable body in the automatic welding apparatus, and is movable, for example, in the front and rear, left and right, and up and down directions. - is an L-shaped holding member that is suspended from the above-mentioned moving body I via a rotation device - so as to be able to freely rotate around the vertical axis, and a holding device fu5 that holds a welding torch α4 is attached to the lower part of the holding member. . The turning device U is composed of an electric motor supported on a support j provided at the lower end of the moving body un and a speed reducer, and one end of the horizontal part (12a) of the holding member is connected to the speed reducer. It is connected and held to the output shaft (18a) of the machine, and a holding device is provided at the lower end of the lower part (12b) of the holding member surface. The holding device will be explained in detail below with reference to FIGS. 3 and 4. U value is welding torch 〇4
This is a holder that directly holds the 4 wooden isosceles trapezoidal plates, each side of which is connected to each other so that they can swing freely and form a pyramidal shape. Among the +19 plates ■, a pair of plates j on the opposite side from the welding torch 041
is oscillated by a oscillating drive device ta, so that the torch angle of the welding torch I can be changed. That is, a shaft portion is provided on the side of the first plate (20A), and a second plate (20B) adjacent to the first plate (20A) is provided.
A cylindrical part (2) is provided on the - side of the shaft part @ so as to be able to swing freely within a predetermined angle range.
An inner cylindrical portion (toward) that holds the welding torch I is provided on the negative side of the plate (20G), and this third plate (20C)
) is provided on the -11111 side of the fourth plate (20D) adjacent to the inner cylinder part (to), and an outer cylinder part (to) is fitted onto the inner cylinder part (to) so as to be able to swing freely within a predetermined angle range; First plate (20
A) and the fourth plate (20D) are also connected to the second plate (20B).
) and the third plate (20C) each have a pair of hinges (
are connected to each other via (to). In addition, the cylindrical part (c)
Cutouts (23a) and (25a) are formed in the outer cylinder part and the outer cylinder part, respectively, so as not to interfere with the shaft part and the inner cylinder part. Furthermore, the tip of the welding torch mouth 4 is located at the point D of the connecting axis extension line of each plate j.
G9 is aligned with the apex of the truncated conical shape formed by U2, and is supported on the side of the holding member via a shaft (support), that is, the holding member U2 has a boss body (support) ) is attached, and the upper part of the shaft part (A) is held on this boss body (A) via a bearing (support).
Note that the 2M portion (c) is held through the upper ml bearing) in FIG. 3. Next, the four-motion drive device (21) will be explained. The rocking drive device (goods) is supported by the holding part support +12.
7) and deceleration d131+, and the output shaft of this deceleration mechanism) (
31a)) C12 and the drive gear head J, and the driven sprocket attached to the upper end of the shaft (2) and driven via the chain end) G2) 13 [i) and a driven gear attached to the upper end of the cylindrical portion (support) and meshed with the driving gear. By connecting in this manner, when the output shaft (18a) rotates in a certain direction, the shaft portion and the cylindrical portion (to) rotate in opposite directions.

, the shaft part (a) and the cylinder part (c) rotate at the same speed and in opposite directions, so for example, the first plate body (20
When A) and the second plate (20B) swing in the direction of spreading, the welding torch I changes its proximal position, that is, the torch angle, as shown from the imaginary line position to the solid line position in FIG. Of course,
At this time, even if the holder 1ull has a hairstyle, the tip of the welding torch I is always at a constant position (the apex of the pyramid). In addition, if it is desired to change the front-rear angle of the welding torch (14+), it is sufficient to swivel the holding member - by the electric motor surface of the swivel device 0.
