Abstract

The invention relates to welding, in particular to electrode holders for manual arc welding with a consumable electrode. The purpose of the invention is to increase the reliability of fixation of the electrode in various spatial positions and to improve the current contact by eliminating the displacement of the points of application of forces. The electrode holder for manual arc welding contains a fixing unit made in the form of a supporting element 5 and a reciprocal pressing element 6. The supporting element 5 is made in the form of a torus and is located on the lever 3. On the torus surface there are made lodges 9 for the electrode 8. mounted simultaneously on both diametrically opposed tool tray 9, ho which makes current contact with the electrode 8. The response pressure element 6 is located on the lever 2 and is made in the form of a trigger, acting as a stop under the electrode 8 and having a working t oor surface. 2 ill.

The invention relates to the field of weld-removal of the cinder of the electrode 8 of the jerk, in particular to electrode holders or dies when the welder compresses the levers of manual arc welding.

The aim of the invention is to increase the pressure-relieved internal securing position of the electrode at the 5th surface of the trigger 6 and is confronted with the false spatial positions and cops 9 of the torus 5 by the lower part of the trigger 6. Improving the current contact by eliminating the electrode holder reliably protection of the bias of the points of application of force. protected from live parts of electrical insulator And fig. 1 is schematically shown in a pre-emptive housing 1, consisting of two lagged electrode holders, general view; S halves and providing full iso of FIG. 2 - section AA in FIG. 1. Lation of live parts from all sides,

The electrode holder for manual arc eliminating arbitrary contact of the current welding comprises a housing 1, two two-gear parts with extraneous metal levers 2 and 3, fixed on the axis 4 with metal objects with which the electrode holder 15 can contact one another in contact fixation in the form of a supporting element (torus) 5 process of work.

and counterpressure element 6, as well as the proposed electrode holder

current lead 7. The floating electrode 8 provides an increase in reliability, is fixed on the lodges 9, which have the electrode tos and current contact with a flat surface and are made in the electrode holder due to the exceptionally diametrically opposite surface during clamping of the electrode - Utoria 5, located on the lever of the point of application of the points of application of force, as well as 3. The counterpressure element 6 of the lever 2, fixing the electrode in various forms in the form of a trigger. The lower part of the trigger is of a comfortable position for 6 It is lowered into the cavity of the torus 5. Thus, 25 drills, due to the presence of a plurality of elements in the support 9 of the elements 5 and the cu {ya in the lodgements on the torus surface, create a stable position of the electrode in the support element in n {X} welding process. On the

opposite ends of two shoulders

guards 2 and 3 behind the axis 4 of their rotation is secured to 30 An electrode holder for a manual arc spring 11 of the clamping of the levers 2 and 3 of the relative welding, comprising a housing, two two each other. Shoulder levers fixed on the axis with

The device operates in the following way, one can be rotated relative to the other, with a clamping spring, the fixation unit. The welder compresses the handles 2 and 3 of the electrode 35 with the supporting and clamping electrode holders, the spring 11 with compressive devices mounted on the levers, and with and supporting elements the flow rate is about. t l and h and y u and with the fact that.

The electrode 8 is mounted on the diameter in order to increase the reliability of fixing the opposite opposite lodges 9 of the electrode torus in various spatial 5, after which the welder only holds in 40 positions and improves the current contact to the hand of the electrode holder, without compressing the rod by eliminating the displacement of the points of the application 11. The electrode 8 is considered to be a set of forces, the support element is made correctly if it touches the form of a torus, on the working surface of which is free of coverage from a section of the middle diametrically opposite parts of the working surface of the trigger are filled in 6.45 lodgements, and the clamping element is located. The electric current is supplied to the melting gold inside the supporting element and the electrode 8 is made. .styu.
