時間と労力を要するという問題がある。By the way, in the conventional cutting tool as described above, it is necessary to accurately align the tip of the cutting tool with the rotation center of the welding tip. That is,
If cutting is performed in a state where the tip of the cutting tool does not reach the center of rotation of the welding tip, the center of rotation of the welding tip remains without being cut (see reference numeral 19 in FIG. 3) . When cutting is performed in a state exceeding the rotation center, cutting is performed in the direction opposite to the cutting direction of the cutting edge at the tip end of the cutting tool, and there is a problem that the cut surface is likely to tear. However, it is difficult to accurately position the tip of the cutting tool at the center of the welding tip, and there is a problem that alignment of the cutting tool requires a lot of time and labor.

It is a side view which shows the state which shaves. Tip of welding tip
Even when the surface is cut and shaped into a plane, it is formed into a spherical shape
There is a similar problem as in the case. Such a problem is illustrated in FIG.
So that the blade 1 of the tip dresser is moved from the proximal end to the distal end.
The problem is solved by forming it into a tapered shape that narrows toward
Can be That is, on both sides of the blade 1
From the base end side of the cutting tool 1 toward the front end side,
A small angle α with respect to an axis perpendicular to the rotation center C of the blade 1
Only inclined. Therefore, when the distal end surface 4 of the welding tips 3 and 3 is cut using the cutting tool 1, the distal end surface 4 of the welding tip 3 is formed in a conical shape having a pointed head on the rotation center C. The taper angle of the front end face 4 is determined by the inclination angle α of the cutting blade 2. If the inclination angle is small, the influence on the welded surface is small . The inclination angle α of the cutting blade 2 is desirably about 0.1 to 2 degrees.

And the tip surfaces 4 and 4 are brought into contact with the cutting blade 2. Next, when the drive source of the tip dresser (not shown) is driven to rotate the cutting tool 1 around the rotation center C,
The tip surfaces 4, 4 of the welding tips 3, 3 are cut and shaped by the cutting blade 2. At a position beyond the center of welding tips 3 and 3,
Since the small angle α is provided, the cutting edge 2 rises from the front end face 4, so that the front end face 4 is not reversely cut by the cutting edges 2 and 2, and tearing does not occur.

The shape of the tip of the welding tip is cut into a spherical shape.
It is a side view which shows a state. The cutting edge 7 of the cutting tool 6 for cutting and shaping the welding tip 5 is formed in a concave arc shape. The center of curvature O of the cutting blade 7 is on the opposite side of the cutting tool 6 with respect to the center of rotation C and is separated from the center of rotation C in the same direction as the tip of the cutting blade 7.
It is provided in the position where it was. Thus, when the cutting blade 7 is applied to the distal end face 8 and the cutting tool 6 is rotated around the rotation center C, the distal end face 8 of the welding tip 5 is formed in a spherical shape .

Since the side slightly rises from the front end face 8, no tearing due to reverse cutting occurs. The center of curvature O of the cutting blade 7 is
A position slightly away from the center of rotation C in the same direction as the tip of the cutting blade 7
It is enough if it is in the place. That is, the center of rotation C and the center of curvature O
Is small, the degree of deformation of the distal end face 8 cut and shaped by the cutting edge 7 is also small, so that the welded finished surface is not adversely affected.
