なっていた。(Problems to be solved by the invention) However, in the conventional device of this type, as shown in the above-mentioned figure, the electrode tightening bolts are provided on the lower outside of the clamp horn. It is difficult to insert a tool such as a wrench into the bolt position, resulting in poor workability.
Moreover, the clamping force of the electrode is applied in the vertical direction as shown by the arrow in FIG. 2, whereas the clamping direction of the electrode is the right angle, that is, the lateral direction. Since the tightening direction is opposite, a slight gap g is generated between the lower surface f of the protective member and the upper surface d of the electrode,
When the electrode 3 is clamped, the electrode surface h is inclined, the contact state between the work surface and the electrode surface is not sufficiently maintained, and high welding quality cannot be obtained. Generally, the parallelism of the upper and lower electrode surfaces is 5/100
Since the following strict accuracy is required, it takes a lot of time and effort to adjust the gap to completely eliminate it.
That was the biggest obstacle to shortening the time for electrode replacement.

講じてある。(Means for Solving the Problem) Therefore, the present invention is to solve the above-mentioned problems, and is a device for attaching an electrode 3 to a clamp horn 1 at a symmetrical position of a butt welding machine. In a device for providing a notch 2 for incorporating an electrode on the inner vertical surface a of the device, and inserting the electrode in the notch to fix the space between the clamp horn and the electrode through the clamping and pressing means B,
The protective member 5 is inserted between the upper surface i of the electrode and the upper surface e of the cutout portion, or between the upper surface of the electrode holder 6 holding the electrode and the upper surface of the cutout portion, and the protective member and the electrode or the protective member A pressing surface is formed between the electrode holder and the inside vertical surface a ′ of the electrode so that the inside becomes gradually lower from the outside, and the pressing surface is interposed between the electrode and the clamp horn from the vertical direction by the pressing means. A technical means has been taken to generate a force that presses the electrode toward the upper surface e of the cutout portion and the side surface b of the cutout portion by applying a tightening force.
(実施例) 以下,本考案にかかる電極取付け装置の実施例を図面に
基づき説明する。(Embodiment) An embodiment of the electrode attaching device according to the present invention will be described below with reference to the drawings.

省略する。FIG. 3 is an outline of the present invention and is a perspective view showing one side of the clamp horn 1 which is symmetrical in the butt welding machine. In the figure, components having the same configurations and functions as those of the conventional components described above are designated by the same reference numerals, and duplicate description will be omitted.

任意の角度をもつテーパ状の加圧面が形成されている。The electrode 3 is inserted into the notch 2 formed on the inner vertical surface a of the clamp horn 1 through the protective member 5 on the upper surface thereof, and the inner vertical surface a of the clamp horn and the inner vertical surface a ′ of the electrode 3 are inserted. And are on the same plane. The surface where the upper surface i of the electrode 3 and the lower surface k of the protective member 5 contact each other has a tapered shape with an arbitrary angle in the range of 91 to 150 degrees with respect to the inner vertical surface of the electrode so that the inside becomes gradually lower. A pressure surface is formed.

れる。The pressing means for tightening the electrode 3 is such that the tightening bolts B are inserted into a plurality of bolt holes O vertically formed in the upper part of the clamp horn, and penetrate the protective member 5 to screw holes provided on the upper part of the electrode 3. The electrodes are screwed together and the electrodes are tightened. By tightening the tightening bolt B inserted in the upper part of the clamp horn, the protective member 5
With the inclined surface where the electrode 3 and the electrode 3 are in contact with each other, the force for naturally pressing the electrode 3 against the side surface b of the cutout portion 2 and the force for pressing against the lower surface k of the protection member are biased in two directions as component forces.

均一に働かない。In this case, when the lower limit of the angle of the pressing surface is 91 degrees or less, the pressing force acting on the side surface of the notch is weak, and when the upper limit is 150 degrees or more, it is applied to the upper surface of the notch. The force exerted is weak, and none of them act uniformly as component force outside the prescribed numerical range.

3図に示す実施例と同様の作用効果が得られる。Although FIG. 3 illustrates the embodiment in which the protective member 5 is directly inserted on the upper surface of the electrode 3, the technical idea of the present invention is not limited to this, and as shown in FIG. 4, for example. In the case where the electrode holder 6 is interposed between the electrode 3 and the protection member 5, a third structure may be used in which a pressing surface having a predetermined angle is formed on the contact surface between the electrode holder 6 and the protection member 5. The same effect as the embodiment shown in the figure can be obtained.

間短縮を可能にする。(Effect of the Invention) As described above, according to the present invention, between the electrode and the protective member 5 facing the electrode, or between the electrode holder and the protective member facing the electrode, the inside of the electrode is gradually increased with respect to the inside vertical surface. By providing a pressure surface with a slanting angle so that it becomes lower, and clamping the electrode vertically from the top of the clamp horn, the component force of the pressing force is generated in two directions, the top direction and the side direction of the clamp horn. Therefore, it is possible to completely eliminate the gap adjustment work, which has been the biggest bottleneck in shortening the work time when replacing electrodes. In addition to ensuring the parallelism of the electrode pressing surface, it is possible to switch the electrode tightening means from the lower position to the upper position of the clamp horn, making it easy to set the tool to the bolt position at an open pace. The bolt attachment / detachment work at the time of replacement has been greatly improved, making it possible to shorten the time for electrode replacement work as a whole.
