This invention relates to devices used in manual arc welding with fusing electrodes.

The purpose of the invention is to improve the safety and reliability of the attachment of the electrodes in various angular positions while reducing the dimensions.

FIG. 1 shows an electrode holder, side view with a local section; in fig. 2 - the same plan view with a monthly incision; in fig. 3 shows section A-A in FIG. one .

The electrode holder includes a housing 1 with a current lead. 2, made) 1st with an I-shaped opening 3, in which on axis 4 with protrusions 5 along the ends there is a hinged electrically insulated lever 6 with a cylindrical protrusion 7,

inside the spring 8, the other end of which is placed in the insulator 9, having a cylindrical protrusion 10, passing through the opening 11 in the housing 1 and entering into the opening 12 in the hollow handle 13, which extends through the through hole 14 of smaller diameter.

. The hollow handle 13 has two open ends of the groove 15 for the protrusions 5 of the axis 4 and a notch 16 for the lever 6. The i-shaped sponge 17 of the housing 1 is bent along an arc in a plane perpendicular to the plane of swing of the lever 6 (in the plane of electrode positions). The sponge 17 is made somewhat for upside down V-shaped sockets 18 for placing the electrodes at different angles to the longitudinal axis of the electrode holder. The protrusion 19 of the quick-detachable heat-resistant electrical insulator 20, which touches the sponge 17 by the plane 21, only along one line, rises above the sponge 17. Rounded from the side of the sponge 17, the sponge 22 of the lever 6 is bent along the opening 3 of the sponge 17.

The sponge 22 is fitted with a quick-detachable heat-resistant electrical insulator 23,

reliable fastening of the electrode in various angular positions with sufficient distance of the welder's hand from the arc. 3 il.

the protrusions 24 of which are included in the sockets 25, made on the sponge 22, and which does not overlap the portion 26 of the sponge 17. In the current lead 2, the tip 27 of the electric cable 28 is installed.

Before assembling the electrode holder, before starting the floor operation, the handle 13 is put on the electric cable 28 until the tip 27 comes out of it. Then the tip 27 is inserted into the current lead 2. An insulator 9 is inserted into the hole 11 in the housing 1, and the spring 8 is inserted into the latter the end of the protrusion 7 of the lever 6 is inserted into it. The axle 4 is inserted into the aligned holes in the housing 1 and the lever 6. After that, the projection 10 is flush flush with the housing 1. All the assembled parts are retracted into the handle 13 by cable 28 to align the projections 5 with the slots 15 and protrusion 10 with a hole 1 2. (They are insulated by electrical insulators 20 and 23. Moreover, their overheat protection is provided by the projections 24 of insulator 23 and by touching the plane 21 of insulator 20 to sponge 17 only along one line.

Electrode works as follows.

By pressing the lever 6 shoulder, its sponge 22 is retracted from the sponge 17. An electrode is inserted into the slots 18 at the required angle all the way into the protrusion 19 of the insulator 20. The lever 6 is released, and the spring 8, acting on the lever arm 6, clamps the electrode between the jaws 17 and 20. At the same time, the correctness of the electrode installation is monitored visually in the open area 26 of the sponge 17. In the non-working electrode holder, when the electrode is not installed in the notches 18, the sponge 22 of the lever 6 is recessed in the opening 3, and the spring 8 is unloaded.

To remove the electrode or its butt, it is enough to press the lever arm 6. To clean the notches, the electric insulator 20 is removed. / To disassemble the electrode holder, the protrusion 10 is pressed down through the hole 14, after which all the parts are pushed out of the handle 13 by pressing the cable 28. disassembly operations are reverse to assembly.

The i-shaped form of the case ensures the installation of the lever and the springs recessed into its opening, which reduces the dimensions of the electrode holder.

Making the jaws of the body and the arm arcuate increases the safety technique by sufficiently removing the welder’s arm from the arc when the electrode is burning and reduces the off-center bending of the jaws relative to the axis of the hinged joint of the lever and the body.

Reliable and stable mounting of the electrodes in any position in the V-shaped sockets made on the body sponge is ensured by

i-shaped opening in the body sponge and the same bending of the body sponge and lever sponge in the plane of the electrode positions.
