Description

Electrode holder for gouging work {ELECTRODE HOLDER FOR GOUGING WORK}

The present invention relates to an electrode holder for a gouging operation (hereinafter referred to as a holder), and in detail, the electric power can be more evenly supplied to both sides of the press lever and the main body constituting the holder, and transmitted only to the main body side. By allowing the air to be supplied branched to the pressure lever side, it is possible to perform a larger operation in the holder of the same size.

In general, gouging is a work for melting and removing a predetermined section of a work, or for melting and removing beads of a badly welded portion or a welded portion more than necessary after performing a welding operation. The same gouging operation is performed by melting a desired portion using a tubular electrode, and then blowing air out through the tubular body by discharging air through the tubular body.

Therefore, in order to perform the gouging operation as described above, a general configuration for supplying electric power and air to the tubular electrode and the electrode is required, the general configuration is a power supply, such as a generator for supplying electric power, air The air supply unit, such as a compressor for supplying, is divided into a holder for transferring the electric power and air to the electrode.

Although the shape of the holder varies depending on the working conditions of the part to be gouged, the most commonly used form is tongs to support the outer surface of the electrode.

1 is a cross-sectional view showing a conventional configuration of such a holder.

Referring to FIG. 1, the holder 1 of the related art includes a hinge coupler 30 formed at a proper portion of the body 10 by a pressure lever 20, and an end portion of the pressure lever 20 and the body 10. A holding part 40 is formed to allow the electrode rod P to be buried therein, and the pressure lever 20 and the main body 10 are opposite to the holding part 40 with the hinge coupling part 30 therebetween. Between the compression spring 50 is mounted is configured.

The main body 10 includes a supply pipe 11 of a conductor through which electric power and air are supplied, and the pressure lever 20 branches only the electric power delivered through the supply pipe 11 to the electrode rod P. And a power supply 21 for the conductor to be supplied.

Here, the hinge coupling portion 30 of the pressure lever 20 and the main body 10 is satisfied by the power supply base 21 and the supply pipe 11 are rotatably coupled to each other by the shaft 31, The holding unit 40 is configured by allowing the power supply base 21 and the end portions of the supply pipe 11 to hold the electrode bar P.

A supply path 12 is formed inside the supply pipe 11, and a valve 13 interposed in the supply path 12 to control the air flowing into the supply path 12 is provided.

In addition, the cable 60 is inserted into the end of the main body 10, the cable 60 is provided with a conductor 61 for supplying power therein on the inner circumferential surface of the sheath, the central portion of the conductor 61 A supply passage 62 penetrates and is connected to the supply passage 12 of the supply pipe 11.

In the conventional holder 1 configured as described above, power and air generated from the power supply unit and the air supply unit (not shown) are supplied to the supply pipe 11 through the cable 60, and the supplied power and air are supplied to the supply pipe 11. When the electrode P is delivered to the electrode P through the supply path 12 of the electrode), the electrode P melts the desired portion of the workpiece and blows out the molten portion to extract the desired portion or weld having a poor working state. The beads are melted and removed.

At this time, the electric power in the air and the air going through the supply pipe 11 is branched to the power supply table 21 through the hinge coupling portion 30 of the supply pipe 11 and the power supply table 21 to the electrode rod (P). Is supplied.

Here, the influence of the specification of the electrode rod on the gouging operation, the diameter is changed depending on the width of the target portion for removing the molten portion and the molten portion in the case of the amount of power received, the melting of the target portion By varying the time required to make the electrode, the electrode is relatively large, depending on its size and the amount of power received, so that the work can be advantageously performed, which makes the molten work part more powerful when performing a wider range of work. It is well known that the air to be blown out must be blown out.

Therefore, when performing the gouging operation using the electrode rod of 8 ~ 10mm or more described above, a separate holder is provided according to each standard, such a configuration of the holder is inserted into the annular member of the electrode rod And fixed by penetrating the bolt from the outer surface of the annular member to the inner surface, which is incompatible because the annular member must be provided separately according to the diameter of each electrode, and the fastening of the bolt tightening method is Inconvenience and the coupling force due to the bolt is a concern that the bolt is loosened during the operation, it is difficult to trust the coupling force.

The present invention has been made to solve the above problems, to hold the electrode rod of 10mm or more in diameter (including the work of less than 10mm) to the larger sized to the size of the holder of the above-mentioned tongs The purpose of the present invention is to provide a holder that is compatible with the size of the electrode, and at the same time it is convenient and stable to take the holding state of the electrode.

In order to achieve the above object, the present invention basically maintains the holder configuration in the form of the tongs described above, and in the configuration of the holding portion for holding the electrode rods so that the air branched with the power supply as well as the supply pipe and power to the power supply and supply pipe This allows for a more even distribution so that a larger amount of compressed air and power is accommodated.
