chips; an electrode fixing unit; a device 12 for removing the butt; and a node for changing the angular position of the electrode. The latter is made in the form of articulated, interconnected x 25 two internal discs, rigidly connected to the lower sponge and having protrusions 21, central and radial grooves, and two soft discs 16, rigidly connected to the body

To change the angle of the electrode relative to the housing, the electric welder presses the jumper 25, disengages the inner discs with the outer disks 16, sets the required angle of inclination of the electrode. The electrode holder reliably clamps the electrode and fixes its angular position, 5 times,

The invention relates to welded production,

The invention of llejib is better than fixing the electrode at a different angle to the axis of the housing.

Fig. 1 shows schematically a general view of an electrode holder with a removed insulating lid; in Fig. 2, the same, with one arm around it and one internal disk jointed with it; PA fig.Z - bracket with the axis and podpruiIen1b1b fixing fingers, side view; FIG. 4, the VLM disk in FIG. 5, an outer disk;

The electrode holder comprises a housing 1 with a handle 2 and a lever ugfra LINE 3, which is connected to the upper jaw 7f of the spring-loaded 5 in the upper part of the spring by means of the rear axle j 4, (not shown). 8, The upper sponge 7 is pivotally connected to the lower sponge 10 by means of an axis 9, which, at the WED, is connected to the conductor 1, In the upper sponge (behind the j section; the electrode) there is a tool for removing the cinder, made in the tab of the protrusion 12 with deepening the placement of the end of the electrode. Inside the handle 2, a node 13 is mounted between the upper jaw and a pawl 14 to fix this node in an inoperative position. In the housing there is a node that changes the angular 1TH electrode, made in the form of two yarn disks 5, rigidly connected to the lower sponge 10, and two , disks 16, rigidly connected to housing 1, external dis10

21, central grooves 22, radial grooves 23 and. Technological holes 24 for mounting the front cable of a 5 with an earring 6. The inner disks 15 are interconnected by means of a cross-box 25 protruding beyond the limits of these disks and intended to bring them out of engagement with external disks 16. In turn, the outer discs 16 have, on the periphery of the cavity 26, designed to accommodate protrusions 21 of the inner discs 15 J of the diaphragm with grooves 27, central holes 28 to accommodate the Axles 17 and technological holes 29, similar to the openings 24 B1- of the morning dis s 15. Bytes central holes 28 of outer discs

Electrode works as follows.

In order to fix an electrode of a certain size with an appropriate force, it acts on the control lever 3, which acts by means of the rear link 4, the front link 5 and the link 6, which are hingedly connected

the upper sponge 7, on the spring 8, squeezing it, and thereby raising the front end of the upper sponge 7. In this open position, the sponge 7 is automatically fixed with the fixing unit 13 without affecting the lever 3 for the required time. The opened jaws into the blind hole of the devices 12 up to the stop and press the lever of the fixing unit 13 of the upper jaw. At this moment, the rods 4 and 5 and the clevis 6 under the influence of the spring 8 return to their original position and thereby lower the front end of the upper jaw 7, clamping the electrode.

If it is necessary to change the angle of inclination of the electrode relative to the axis of the body of the electrode holder, in order to facilitate welding at certain places of the structure to be welded, unlock the front link 5 with the pawl 14 of the node 13. Then use the thumb to jumper 25, move the grooves 22 internal discs 15 and pal1f 19 along the grooves 27 of the outer discs 16 forward, the protrusions 21 are released from engagement with the depressions 26 of the outer

The proposed electrode holder makes it possible to securely fix the electrode and its angular position.
