    The invention relates to a fastening system of a burner body of a TIG welding torch to a burner handle, wherein the burner body comprises a cylindrical plug element with a fastening element and the burner handle a coupling for releasably receiving the plug element, and systeir on the fortifications. at least the media gas and electricity are transferable.
    The invention likewise relates to burner bodies for the fastening system of a TIG welding torch.
    The invention also relates to a TIG welding torch with the fastening system and the burner body.
    Depending on the requirement of the welding process to be carried out, different welding torches are preferably used. So that it is not necessary to exchange the entire welding torch with the hose package fastened to it, the torch bodies -which constitute a part of the welding torch - are exchangeable. In particular, TIG welding torches are frequently changed due to the high loads. For the change of the burner body of a TIG welding torch corresponding devices from the prior art are known.
    Thus, US 4,049,943 shows the change of burner bodies, wherein both an electrode holder and a TIG torch body to the coupling, which is connected to the hose package, can be fastened. In this case, the plug-in element of the burner body accommodated by the coupling is fastened via balls. These balls are arranged in the coupling and engage in a groove of the plug element. To transfer the gas from the coupling into the burner body, a valve is actuated during the attachment of the plug element. The disadvantage here is in particular that the balls increase the clutch and a complex and trouble-prone valve is required.
    From US 6,706,994 Bl further a change of the burner body is known. In this case, a separate quick release is provided for the individual media, so that the burner body is replaceable. The quick fasteners are protected by half shells. The disadvantage here is that the change of the 2nd
    Burner body several steps are required because the half shells must first be removed and each quick release must be opened individually. Likewise, the size of the burner is increased by the separate media guide and the position of the burner body can not be 'changed.
    The object of the invention is to make the burner body of a TIG welding torch replaceable, wherein the size of the TIG welding torch remains unchanged.
    The object is achieved in that the fastening element is arranged between a gas element and a current element of the plug element, wherein in the coupling of the burner handle a fixing element is arranged, which engages in the fastening element, and that the gas element for guiding over the coupling arranged in the fixing element has a smaller diameter than the fastening element and the current element, and that the fastening element has a flat position, so that the fastening element with the flat position on the fixing element can be guided while the gas element is arranged sealingly in a gas bore of the coupling.
    The advantage here is that the torch body can be changed without tools and quickly by a simple plug and rotary movement. As a result, the burner body can also be easily adapted to the required power. Furthermore, this results in low downtime during the change, for example, in a damage to the burner body. Likewise, advantageously, the position of the burner body for the welding process can be quickly adapted to the workpiece, so that always the optimum accessibility is ensured. It is also advantageous that existing burner handles can be converted by the space-saving design of the fastening system. Accordingly, the size of the existing TIG welding torch is not changed by the fastening system according to the invention. Another advantage is that the burner body can only be attached as soon as the gas seal is made, which automatically ensures the gas seal for each position. Another advantage is that with only one hose package different welding torch performance classes are given on the choice of the respective exchangeable burner body. The advantage is that no disturbing contours outside of the burner handle thereby arise.
    By the measure that the position of the burner body is freely adjustable with a manual rotary movement, wherein the Fi-xierelement is guided in a circumferential groove of the fastener, is achieved in an advantageous manner that the position is adjusted exclusively by the rotational movement, wherein the lock the burner body via the fixing takes place.
    It is also advantageous if a cone between the groove and a web of the fastener is arranged, wherein the cone is tapered in the direction of the groove, so that the guide for adjusting the position of the burner body is improved by the cone and the plug element from the cone in the clutch is held.
    Advantageously, by the measure that at the opposite end of the gas element a stop is arranged reaches a noticeable position, so that the burner body can be fixed by the rotational movement and the position can be adjusted and the gas tightness is given.
    By the measure that a spring element is positioned in front of the stop, an additional current transition over the stop and the front side of the clutch is achieved in an advantageous manner, since the spring element ensures a secure contact. At the same time, a pressure is built up between the cone and fixing element and undesired rotation of the position of the burner body is made more difficult.
    It is also advantageous for reasons of tightness, if a groove for a sealing ring in the gas element is arranged. Also, a simple control of the sealing ring is possible here, since this is arranged on the plug-in element of the exchangeable burner body. Thus, the sealing ring remains when changing the plug-in element, so that the user can easily control this and replace it if necessary. - 4 - • t (··· · · ♦ · · # ··· ♦ · ·
    Advantageously, the measure that the gas element has a flat, which is aligned with the flat portion of the fastener, a better detection of the flat reaches the fastener.
    By the measure that two concentric holes for the plug element are arranged in the coupling, wherein a bore is formed as a gas bore and the further bore as a current bore, a simple receptacle for the plug element and a simple seal and a simple power transition is achieved.
    It is also advantageous that the fixing element is arranged in the current bore in the form of a circular segment and at this point reduces a diameter of the current bore, whereby at the same time the attachment and a current transition is achieved.
    Advantageously, is achieved by the measure that the coupling is cylindrical and formed in the region of the fixing a cuboid around the coupling, that the fixing element can be mounted from the outside and at the same time produces the circular segment in the current bore. Thus, the fixing element can also be changed easily after it is too worn by the rotational movements.
    Likewise, the object of the invention in a burner body as indicated is achieved in that the plug element of the burner body is formed of a gas element, a current element and a fastener arranged therebetween, wherein the position of the burner body is infinitely adjustable by a manual rotational movement.
    Advantages of this and the measures of the dependent claims can be found in the advantages already described for the fastening system.
    The object of the invention in a TIG welding torch as indicated is achieved in that the burner body is rotated by 180 ° to the usual welding position of the TIG welding torch and with the flat part of the fastener on the fixing in the burner handle is inserted, the burner body by a Rotary movement is fixed and the welding position is adjustable via the rotational movement.

    In the drawings, like parts of the embodiment are provided with the same reference numerals.
    In Fig. 1, a welding apparatus 1 or a welding system for a variety of processes or processes, such. MIG / MAG welding or TIG / TIG welding or electrode welding, double wire / tandem welding, plasma or soldering, etc. are shown.
    The welding apparatus 1 comprises a power source 2 with a power unit 3, a control unit 4 arranged therein, and a control unit 4, and a power supply unit 6. For example, the control device 4 is connected to a control valve, which is arranged in a supply line for a gas 5, in particular a protective gas. such as C02, helium or argon and the like., Between a gas storage 6 and a welding torch 7 and a burner is arranged.
    In addition, a wire feeder 8, which is customary for MIG / MAG welding, can be actuated via the control device 4, wherein a filler material or a welding wire 9 from a supply drum 10 or a wire reel into the area of the welding torch 7 via a supply line is supplied. Of course, it is possible that the wire feeder 8, as known from the prior art, in the welding device 1, in particular in the housing 11 of the power source 2, is integrated and not, as shown in Fig. 1, as an additional device on a carriage 12th is positioned. Here is spoken of a so-called compact welder 1. It is also possible that the wire feeder 8 can be placed directly on the welder 2, that is, that the housing 11 of the power source 2 is formed on the top for receiving the wire feeder 8, so that the carriage 12 can be omitted.
    It is also possible for the wire feed device 8 to supply the welding wire 9 or the additional material outside the welding torch 7 to the processing station, for which purpose a non-consumable electrode is preferably arranged in the welding torch 7, as is usual in TIG / TIG welding.
    The current for constructing an arc 13, in particular a working arc, between the electrode or the welding wire 9 and a workpiece 14 preferably formed from one or more parts is from a power line 3, not shown, from the power source 2, the welding torch 7, in particular the electrode or the welding wire 9, supplied, wherein the workpiece to be welded 14 via a further welding line for the further potential, in particular the ground cable, with the power source 2, not shown, is connected, and thus via the arc 13 and The formed plasma jet for a process can be built a circuit. When using a burner with internal arc 13, the two welding lines, not shown, led to the burner so that a corresponding circuit can be constructed in the burner, as can be: Plasma burners oer case.
    For cooling the welding torch 7, the welding torch 7 can be connected with interposition of ev. Components, such as a flow monitor, with a liquid container, in particular a water tank 16 with a level indicator 17, whereby upon start-up of the welding torch 7, the cooling device 15th , in particular a liquid pump used for the liquid arranged in the water tank 16, is started and thus a cooling of the welding torch 7 can be effected. As shown in the illustrated embodiment, the cooling device 15 is positioned on the carriage 12, on which then the power source 2 is placed. The individual components of the welding system, that is, the current source 2, the wire feed device 8 and the cooling device 15, are designed such that they have corresponding projections or recesses, so that they can be safely stacked on each other or placed on each other.
    The welding device 1, in particular the current source 2, further has an input and / or output device 18, via which the most varied welding parameters, operating modes or welding programs of the welding device 1 can be set or called up and displayed. In this case, the welding parameters, operating modes or welding programs set via the input and / or output device 18 are forwarded to the control device 4 and from this the individual components of the welding system or the welding device 1 are subsequently controlled or corresponding setpoint values for regulation or control are specified. In this case, it is also possible that with the use of a corresponding welding torch 7 adjusting operations can also be carried out via the welding torch 7, with the welding torch 7 being equipped with a welding torch input and / or output device 19 for this purpose. The welding torch 7 is preferably connected via a data bus, in particular a serial data bus, to the welding device 1, in particular the current source 2 or the wire feed device 8. To start the welding process, the welding torch 7 usually has a start switch, not shown, so that the arc 13 can be ignited by actuating the start switch. In order to be protected against the high heat radiation from the arc 13, it is possible that the welding torch 7 is equipped with a hit-zeschutzschild 20.
    Furthermore, in the illustrated embodiment, the welding torch 7 is connected via a hose package 21 to the welding device 1 or the welding system, wherein the hose package 21 is attached to the welding torch 7 via a bend protection 22. In the hose package 21, the individual lines, such as the supply line or lines for the welding wire 9, for the gas 5, for the cooling circuit, for data transmission, etc., are arranged from the welding device 1 to the welding torch 7, whereas the ground cable preferably is connected to the power source 2 extra. The hose assembly 21 is connected via a coupling device, not shown, to the power source 2 or the wire feeder 8, whereas the individual lines are secured in the hose assembly 21 with a kink protection on or in the welding torch 7. In order for a corresponding strain relief of the hose assembly 21 is ensured, the hose assembly 21 may be connected via a strain relief device, not shown, with the housing 11 of the power source 2 or the wire feeder 8.
    In principle, not all of the previously named components must be used or used for the different welding methods or welding devices 1, such as TIG devices or MIG / MAG devices or plasma devices. Thus, it is possible, for example, that the welding torch 7 can be designed as an air-cooled welding torch 7, so that, for example, the cooling device 15 can be dispensed with. It can therefore be said that the welding device 1 is formed at least by the current source 2, and the wire feed device 8, optionally also and the cooling device 15, wherein these components can also be arranged in a common housing 11. Furthermore, it is possible that other parts or components, such as a> · · · »k ft *« «*» «ft • · # · · · · · · · · 4 ft ··« * · · · 4 ** ··· · · «« * * · · * * ft ft ft - 9 - ..............
    Abrasive contactor 23 on the wire feeder 8 or an option carrier 24 on a holding device 25 for the gas storage 6, etc., can be arranged or used.
    Furthermore, it is known that the welding torch 7 for TIG Schwet Ssen from a Brenr.ergrif £ 26 and a burner body 27 is formed. In this case, the burner handle 26 is connected to the hose package 21 and the burner body 27 is detachably connected to the burner handle 26, so that the burner body 27 is replaceable. Correspondingly, the burner body 27 has a plug-in element 28 and the burner handle 26 has a coupling 29, which can be detachably connected via a fastening element 30 and transmit both the welding current and the protective gas 5. Thus, a fastening system 31, in particular for TIG manual welding torch, formed.
    According to the invention, it is now provided that the fastening element 30 is arranged between a gas element 32 and a current element 33 of the plug element 28, wherein in the coupling 29 of the burner handle 26, a fixing element 34 is arranged, which engages in the fastening element 30, and that the gas element 32 for Guide over the clutch 29 arranged in the fixing element 34 has a smaller diameter than the fastening element 30 and the power element 33, and that the fastening element 30 has a flat 35, so that the fastening element 30 with the flat 35 on the fixing element 34 is feasible and at the same time Gas element 32 is arranged sealingly in a gas bore 37 of the coupling 29.
    This fastening system 31 will be described below in conjunction with FIGS. 2 to 9 in detail.
    According to the fastening system 31, the coupling 29 and the plug-in element 28 are formed correspondingly corresponding. Thus, the plug-in element 28 is cylindrical, wherein the gas element 32 has a smaller diameter than the fastening element 30 and the current element 33. Correspondingly, the coupling 29 has two concentric bores. Essentially, the gas bore 37 serves for the transmission of the protective gas 5 and a current bore 38 for the transmission of the 10 1...

    Welding current, respectively from the coupling 29 to the plug element 28 for TIG welding - preferably with a manual welding torch. Accordingly, substantially the current to the power element 33 and the gas 5 in a Gaskana.l the SLeckelernents 28 is transmitted. Thus, the male member 28 has been inserted and fixed in the holes of the coupling 29.
    The attachment is carried out in accordance with the fastening element 30, which releasably and rotatably secured in accordance with the plug-in element 28 in the coupling. For this purpose, the fastening element 30 has a web 39 and a groove 36, wherein the web 39 is arranged on the side of the gas element 32 and the groove 36 on the side of the current element 33. In this case, the diameter of the web 39 corresponds to the diameter of the flow element 33, wherein the radius of the groove 36 is substantially matched to the distance between the flat 35 and the central axis 40 of the fastening system 31 - in this case the plug element 28. Furthermore, the groove 36 creates a free space for the fixing element 34 of the coupling 29. This clearance is required because the fixing element 34 reduces the diameter of the flow bore 38 at this point. Likewise, the free space allows the burner body 27 to rotate. For example, the fixing element 34 has the shape of a circle segment. The radius of the gas bore 37 is therefore smaller by the segment height than the radius of the current bore 38. The fixing element 34 thus represents an increase in the current bore 38 of the coupling 29 Accordingly, the diameter of the flow bore 38 is reduced at this point of elevation. In principle, the fixing element 34 is arranged in the front region of the flow bore 38, that is to say at a distance in front of the gas bore 37. The distance between the fixing element 34 and the gas bore 37 corresponds at least to the width of the web 39.
    So that this increase does not affect the insertion of the plug element 28 into the coupling 29 up to a stop 41 of the plug element 28, the diameter of the gas element 32 is smaller and the fastening element 30 is formed with a flat point 35.

    Thus, the male member 28 may be inserted in any position in the coupling 29 until the stepped transition between the gas element 32 and the web 39 of the fastener 30 abuts the fixing member 34. In this case, therefore, the burner body 27 was inserted substantially in the welding position in the coupling 29, as shown in FIG. 6. In this state, there is already a part of the gas element 32 in the gas bore 37. This part is located in front of a sealing ring 42, which is arranged in a groove 43 of the gas element 32. Accordingly, the gas bore 37 is not yet sealed and the burner body 27 is not yet attached.
    Accordingly, the user of the burner body 27 and thus the plug element 28 is rotated manually until the flat 35 forms a plane with the chord of the circle segment.
    Thus, after the burner body 27 has been rotated to the correct position, it can be inserted as far as the stop 41 (FIG. 7). At the same time, the groove 36 is pushed into the plane of the fixing element 34 and the sealing ring 42 into the gas bore 37 until the stop 41 of the plug element 28 touches the end face of the coupling 29. The sealing ring 42 has an outer diameter which lies between the diameter of the gas element 32 and the diameter of the web 39. Thus, the sealing ring 42 is narrowed accordingly when inserted into the gas bore 37 and thereby ensures the tightness.
    In this mated condition, the torch body 27 can be manually twisted and fastened (FIG. 8), held by a cone 44. In this case, the cone 44 is disposed between web 39 and groove 36. In addition, cone 44 compensates for the different diameters of land 39 and groove 36 and provides a transition. Thus, torch body 27 is held by urging cone 44 against fixing element 34. If, for example, the fixing element 34 is sprung, this additionally exerts a force on the cone 44, so that the position of the burner body 27 is fixed with an increased force. Thus, it is also ensured that the burner body 27 is kept unchanged during a welding operation in the set position.
    The position of the burner body 27 can be adapted and / or adjusted substantially arbitrarily to the welding operation to be performed by the burner body 27 is rotated and thus takes place a lock. The positions for the burner body 27 can therefore be chosen arbitrarily on the length of the cone 44. In this case, the length is essentially formed by the circumference, with the flat 35 correspondingly interrupting the circumference of the circumference and thus shortening the cone 44. As a result, an angle for continuously adjusting the position is given accordingly. For example, this angle is in the range of 320 °.
    In addition, the holding force can be increased if a spring element 45, for example a spring ring, is positioned on the plug-in element 28 in front of the stop 41. In this case, the spring element 45 correspondingly resilient and highly electrically conductive properties. Accordingly, the spring ring is arranged in the assembled state between the stop 41 and the end face of the coupling 29, so that the plug element 28 is pressed substantially from the coupling 29 and the cone 44 is pressed against the fixing element 34 reinforced.
    The fixation of the position of the burner body can also take place and / or at least be supported by an insulated friction surface is arranged both in the burner body 27 and in the burner handle 26 in the region of the stop 41, so that a frictional force is exerted. Accordingly, the frictional force with the rotational movement must be overcome in order to adjust the position of the burner body 27.
    Furthermore, the fastening element 30 and the gas element 32 may be formed by a separate part, which is correspondingly connected to the current element 33, for example by a solder and / or press connection. In this case, for example, the independent part of steel, chrome-nickel or the like - ie a hard material - formed so that the material is not deformed due to the holding force. In contrast, the current element 33 is made of copper or brass, for example, so that a good current transition is guaranteed 13.
    In principle, the coupling 29 is also cylindrical. In this case, the supply lines for the welding current and the protective gas 3 are arranged at an end region of the cylinder, whose connections are substantially known from the prior art. Accordingly, the gas bore 37 and the flow bore 38 are arranged at the other end region. A cuboid 46 is essentially arranged between these end regions, ie essentially in the middle of the coupling 29. This cuboid 46 serves to mount the fixing element 34. For this purpose, the cuboid 46 has a fixing bore 47, for example, which faces the center axis 40 of the fastening system 31 - In this case, the coupling 29 - is offset by 90 ° and thus arranged radially. In this case, a part of the fixing hole 47 intersects with the current bore 38. That is, for example, the center axis of the fixing hole 47 intersects the circumference of the current bore 38 at one point. In this case, the central axis of the fixing hole 47 thus corresponds to a tangent. Likewise, the central axis of the fixing hole 47 may also be designed as a passante. If the fixing element 34 is now fixed in the fixing bore 47, the circular segment results in the current bore 38 in the region of the intersection of the current bore 38 and the fixing bore 47. For example, the fixing element 34 is formed by a spring bushing, a clamping sleeve or the like. Accordingly, therefore, the fixing element 34 is cylindrical, wherein the fixing element 34 may also have resilient properties. Thus, the circle segment is formed in a section through the cuboid 46. In a three-dimensional view, it is not a circle segment, which accordingly has an elliptical shape, but a spherical segment in elliptical shape.
    Furthermore, a plurality of slots 48 are arranged in the jacket of the power hole 38, so that jaws 49 arise. As a result, the diameter of the flow bore 38 is at least slightly reduced. This is done accordingly by reducing the residual stress of the shell. Accordingly, during insertion of the plug-in element 28, the jaws 49 resulting from the slots 48 are pushed apart so that the jaws 49 are pressed against the plug-in element 28 14, resulting in an improved current transition. In addition to or instead of the slots 48, lamellae can also be arranged in the current bore 38, which also improves the current transition.
    Preferably, the fixing element 34 is arranged in the burner handle 26 above. Accordingly, the fixing element 34 is arranged substantially below a burner button 50, wherein the burner button 50 is arranged correspondingly on the upper side of the burner handle 26.
    In contrast, the flat 35 is aligned on the plug-in element 28 downwards, ie in the direction of a gas nozzle 51 of the burner body 27th
    Thus, it is provided that the burner body 27 is rotated substantially by 180 ° to the usual welding position and is introduced with the flat portion 35 of the fastening element 30 via the fixing element 34 in the coupling 29 in the burner handle 26. As a result, the position of the burner body 27 for welding operations is substantially adjustable in the lower semicircle or angle range by the rotational movement, and thereby an unintentional release of the burner body 27 is excluded. Likewise, the burner body 27 is fixed by the rotational movement and set the welding position on the rotational movement. Of course, the fastening system 31 according to the invention is designed for use in gas-cooled and water-cooled welding torches 7.
