Description
Technical field
the utility model relates to a kind of welding gun, particularly a kind of 90 degree of elbow internal wall built-up welding welding guns.
Background technology
at present, 90 degree of elbow internal wall built-up welding welding guns adopt gear train transmission substantially, its structure chart as shown in Figure 1, because the transmission between gear train needs power transmission shaft, power transmission shaft must be straight, and this just requires that welding gun supports loop bar must be straight, with because be subject to the restriction of bend pipe internal diameter, causing welding gun place gear to do can not do too large, greatly limit the increase of H value, and then greatly limit the size of built-up welding bend pipe.
Utility model content
the purpose of this utility model is to overcome the deficiency of prior art and provides a kind of built-up welding welding gun being suitable for 90 degree of elbow internal walls welding of more large gauge.
the utility model adopts following technical scheme:
a kind of 90 degree of elbow internal wall built-up welding welding guns, comprise gear-box, drive motors, arc welding gun head, driven wheel on gear-box is meshed with gear wheel, driven wheel is connected with drive motors, it is characterized in that: gear wheel is contained in welding gun and supports on loop bar, welding gun supporting loop bar is curved structure, the tail end of curved structure is placed in 90 degree of bend pipes, and the travelling gear on pinion casing is equipped with in the front end of welding gun support loop bar, and this travelling gear is meshed with pinion, pinion is connected with small machine, and described pinion casing is equipped with arc welding gun head assembly.
the utility model adopting technique scheme compared with prior art, can enter specification adjustment according to the different size of 90 degree of bend pipes, can be suitable for the welding gun of 90 degree of elbow internal walls of more large gauge.
the preferred version that the utility model adopts is:
be connected by bearing between travelling gear with pinion casing.
welding gun supporting loop bar in curved structure is connected in sequence by the horizontal loop bar in front end, front end inclination loop bar, parallel loop bar, rear end inclination loop bar and the horizontal loop bar of tail end.
travelling gear and gear wheel are positioned on same axis.
the centre of gyration of travelling gear is hollow shape structure, and the centre of gyration of this travelling gear is equipped with arc welding gun head.
travelling gear supports loop bar by screw and welding gun and is connected.
Accompanying drawing explanation

fig. 3 is the top view (A in Fig. 2 is to sectional view) of pinion stand.
Detailed description of the invention
below in conjunction with drawings and Examples in detail the utility model is described in detail:
a kind of 90 degree of elbow internal wall built-up welding welding guns, see in accompanying drawing 2 to accompanying drawing 3, figure: drive motors 1, gear-box 2, driven wheel 3, gear wheel 4, connecting axle 5, welding gun support loop bar 6, the horizontal loop bar in front end 601, front end inclination loop bar 602, parallel loop bar 603, rear end inclination loop bar 604, the horizontal loop bar 605 of tail end, pinion casing 7, travelling gear 8, bearing 9, arc welding gun head assembly 10, pinion 11, small machine 12.
in the present embodiment, driven wheel 3 on gear-box 2 is meshed with gear wheel 4, driven wheel 3 is connected with drive motors 1, gear wheel 4 is contained in welding gun and supports on loop bar 6, welding gun supporting loop bar 6 is in curved structure, and the tail end of curved structure is placed in 90 degree of bend pipes, and the travelling gear 8 on pinion casing 7 is equipped with in the front end of welding gun support loop bar 6, this travelling gear 8 is meshed with pinion 11, and pinion 11 is connected with small machine 12; Arc welding gun head assembly 10 pinion casing 7 is equipped with.
be connected by bearing 9 between travelling gear 8 with pinion casing 7.
welding gun supporting loop bar 6 in curved structure is connected in sequence by the horizontal loop bar in front end 601, front end inclination loop bar 602, parallel loop bar 603, rear end inclination loop bar 604 and the horizontal loop bar 605 of tail end.
travelling gear 8 and gear wheel 4 are positioned on same axis.
the centre of gyration of travelling gear 8 is hollow shape structure.
the horizontal loop bar 605 of tail end that the excircle of travelling gear 8 is supported in loop bar 6 by screw and welding gun is connected.
the welding gun supporting end construction of loop bar 6 in curved structure and the length of 90 degree of bend pipes adapt; In processing use procedure, the angle of inclination of rear end inclination loop bar 604 and the length of 90 degree of bend pipes adapt.
driven wheel 3 drives gear wheel 4 to rotate, gear wheel 4 drives welding gun to support loop bar 6 and rotates that (velocity of rotation that welding gun supports the velocity of rotation of loop bar 6 and workpiece is harmonious, welding gun is made to support loop bar 6 forever constant with the relative position of workpiece, avoid interfering), welding gun supports loop bar 6 and is connected with the travelling gear 8 of pinion casing 7, rotates together.Now, small machine 12 on pinion casing 7 drives pinion 11 to rotate, its velocity of rotation and gear wheel 4 rotating speed coordinate that (speed is consistent mutually, turn to contrary), ensure pinion casing 7 geo-stationary, now, arc welding gun head assembly 10 is installed in the front end of pinion stand casing 7 and can ensures welding gun geo-stationary.
the present embodiment, only needing to design a kind of welding gun support loop bar 6 adapted according to the weldment of different size can meet welding requirements, and the present embodiment can adapt to more specification of workpieces than prior art, substantially increases the scope of application of the present utility model.
