DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting torch having an angle adjusting mechanism.

[0002]

2. Description of the Related Art A conventional cutting torch does not have an angle adjusting function. For this reason, quantitative adjustment cannot be performed, so that much time is required for positioning. This is shown in FIGS. 7 (a) and 7 (b) and FIG.
This will be described in more detail based on (c) and (d). 7A is a front view, FIG. 7B is a left side view of FIG. 7A, and FIG.
FIG. 8A is a view taken along the line XX, and FIG. 8D is a top view of FIG. 7 and 8, a is a cutting torch, b is a marking torch, and c is a torch holder. In such a cutting torch a, in order to adjust in the x direction (see FIG. 8D), the bolt e is loosened, and the torch holder c is moved relative to the mounting bracket h with respect to the rotation center O _{1 in} the x direction. After rotating an appropriate amount around, the bolt e is tightened, but the exact adjustment amount cannot be grasped. To adjust in the y direction,
Loosen the number of bolts f and bolts g, bets only to the extent of the gap portion of the bolt and the bolt hole - after the Chihoruda c rotated around the y-direction rotation center O _2, but tighten the bolt f and bolts g, which also It is not possible to accurately grasp the amount of adjustment.

[0003]

SUMMARY OF THE INVENTION In view of the above-mentioned problems of the prior art, it is an object of the present invention to provide a cutting torch provided with an angle adjusting mechanism capable of easily adjusting an angle and accurately grasping an adjustment amount.

[0004]

A torch holder for incorporating a cutting torch, a rotating shaft for supporting the torch holder, and a torch holder supporting the rotating shaft fixed and held by bolts. An arm 22 and a rotating shaft support bracket supporting arm 21 fixed to the rotating shaft support bracket 4 with bolts 6.
The torch holder supporting arm 22 is provided with an adjusting bolt 16 and a fixing nut 17 having an upper end contacting the torch holder 2 at the upper portion, and a lower end contacting the torch holder 2 at the lower portion. A spring plunger 18 and a nut 19 are attached, and the rotation support bracket support arm 21 is provided.
The upper part has an adjustment bolt 12 and a fixing nut 13 whose tip comes into contact with the torch holder support arm 22, and the lower part has a spring plunger 14 and a nut 15 attached, so that the x-axis direction and the y-axis direction can be adjusted. I made it.

[0005]

The nut 17 is loosened, the adjusting bolt 16 is turned by a pre-calculated rotation angle, the nut 17 is prevented from loosening, the adjustment is performed in the x direction, the nut 13 is loosened, and the adjusting bolt 12 is rotated in advance by the pre-calculated rotation angle. By turning the nut, the nut 13 is prevented from loosening, thereby enabling adjustment in the y direction.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1 is a front view, FIG. 2 is a left side view, FIG. 3 is a right side view, and FIG.
5 is a plan view, and FIG. 6 is a view taken in the direction of the arrow Y in FIG.
In the figure, 1 is a cutting torch, 2 is a torch holder, and 3 is a rotating shaft. 4 is a rotating shaft support bracket for supporting the rotating shaft 3,
5 is a mounting bracket. 6, 7 and 20 are bolts,
8, 10, 14 and 18 are spring plungers, 9,
Numerals 11, 13, 15, 17, and 19 are nuts. 12
And 16 are adjusting bolts, 21 is an arm for supporting the rotating shaft support bracket, and 22 is a torch support arm.

[0007] The cutting torch 1 is incorporated in a torch holder 2. The rotating shaft 3 is a torch holder supporting arm 2
The end is fixed to 2 by a bolt 7 (see FIG. 6). The rotating shaft supporting bracket 4 and the rotating shaft supporting bracket supporting arm 21 are fixed by bolts 6 (FIGS. 3 and 5), and the rotating shaft supporting bracket 4 and the mounting bracket 5 are fixed by bolts 20. The torch holder 2 is inserted into the rotating shaft 3, the spring plunger 10 is screwed into the V-groove (FIG. 6) of the torch holder 2, and loosened with a nut 11.

The rotating shaft 3 is inserted into the rotating shaft support bracket 4, the spring plunger 8 is screwed into the V-shaped groove of the rotating shaft 3, and the spring plunger 8 is prevented from being loosened by the nut 9. The adjusting bolt 16 and the nut 17 are provided on the upper part of the torch holder supporting arm 22.
However, a spring plunger 18 and a nut 19 are attached to a lower part. Rotary shaft support bracket support arm 2
1 is provided with an adjustment bolt 12 and a nut 13 at an upper part, and a spring plunger 14 and a nut 15 at a lower part. The spring plunger 14 and the spring plunger 18 are fixed at a position half of the stroke.

The torch holder 2 has a rotation center O _{1 in the} x direction and a rotation center O ₂ in the y direction. In the x-direction, the outer surface of the torch holder 2 is restrained by an adjustment bolt 16, a nut 17, a spring plunger 18, and a nut 19. In the y direction, the outer surface of the torch holder 2 is restrained by the adjustment bolt 12, the nut 13, the spring plunger 14, and the nut 15.

In this embodiment, an adjusting bolt and a nut are used as upper parts and a spring plunger and a nut are used as lower parts.
Parts such as knobs are also conceivable. Further, the adjusting parts are not limited to those described above, nor are the upper and lower mounting positions limited.

[0011]

[Operation] The angle of the cutting torch 1 is adjusted by the following method. x
To adjust the direction, the nut 17 (FIG. 1) is loosened, the adjustment bolt 16 is turned by the rotation angle calculated in advance with respect to the adjustment amount, and the nut 17 is prevented from loosening. For adjustment in the y direction, the nut 13 (FIG. 5) is loosened, the adjustment bolt 12 is turned by the rotation angle calculated in advance with respect to the adjustment amount, and the nut 13 is prevented from loosening. The rotation angle of the adjustment bolt with respect to the adjustment amount is determined by the following three conditions. Position of Rotation Center, Position of Adjustment Bolt, Thread Pitch of Adjustment Bolt While the cutting torch 1 has been described above, this structure can also be applied to a marking torch.

[0012]

[Effect] Two rotation centers in the x-axis direction and the y-axis direction are provided,
Loosen the nut 17, turn the adjusting bolt 16 by a pre-calculated rotation angle, stop the nut 17 from loosening, adjust in the x direction, loosen the nut 13, adjust the adjusting bolt 12
Can be adjusted in the y-direction by locking the rotation nut 13 by a rotation angle calculated in advance, and the adjustment in the y direction can be performed. Therefore, the adjustment amount can be accurately grasped, and the quantitative adjustment can be easily performed. Was.
