Abstract
The utility model provides a repairing welding device of cavity inner welded seams, and the repairing welding device can solve the problem that an existing repairing welding device can not carry out reliable repairing welding on defected welded seams in the cavity, thereby reducing product scraps and reducing production cost. The repairing welding device comprises a tungsten inert gas (TIG) welding gun, and is characterized by further comprising a camera device and a display screen. A handle of the TIG welding gun is arranged on an extending rod, and the camera device is arranged on a side of a ceramic protective hood of the TIG welding gun, and the camera device is connected with the display screen in an electric controlling mode.
Description
Technical field
The utility model relates to the repairing welding field of interior die cavity weld seam, is specially a kind of repair welding equipment of die cavity inside weld.
Background technology
the member that has interior die cavity weld seam for hollow stationary blade etc., because the welding gun of the repair welding equipment (TIG argon tungsten-arc welding) of routine exists rifle head volume large, the reasons such as inconvenient operation, add upper impression long and narrow, volume is little, internal light is not enough, cause the repair welding welding gun to be not easy to stretch into die cavity inside, even and the repair welding welding gun can stretch into die cavity inside, also because inner dark, volume is narrow and small can't judge defective locations, and be difficult to grasp the welding gun motion conditions in process of patch weld, therefore when there is weld defect in die cavity inside weld member, be difficult to repair and cause scrapping.In Fig. 1,9 for treating the die cavity weld seam of repair welding.
Summary of the invention
For the problems referred to above, the utility model provides a kind of repair welding equipment of die cavity inside weld, and it can solve existing repair welding equipment can't carry out to poor weld in die cavity the problem of reliable repair welding, thereby reduces scrapping of product, reduces production costs.
Its technical scheme is such; it comprises the TIG welding gun; it is characterized in that: it also comprises camera head and display screen; the lever of described TIG welding gun is installed on extension rod; the ceramic protection cover avris of described TIG welding gun is equipped with described camera head, and described camera head and described display screen electricly connect.
It is further characterized in that:
Described camera head is installed on front side or the rear side of the ceramic protection cover of described TIG welding gun, and the angle β between described camera head and welding gun tungsten electrode axis direction is at 20 °～70 °, between the tungsten electrode of described camera head and described welding gun is top is 10mm～60mm apart from d, and it is top that the image pickup scope of described camera head covers described tungsten electrode;
Described camera head is any in camera, endoscope head.
adopt the utility model repair welding equipment, its beneficial effect is: the lever of its TIG welding gun is installed on extension rod, the ceramic protection cover avris of TIG welding gun also is equipped with camera head, and camera head and display unit electricly connect, can be easily stretch in die cavity welding gun tungsten electrode is top by extension rod, the camera head of welding gun ceramic protection cover avris can be taken the weld seam situation in die cavity and shown by display screen simultaneously, operating personnel can be shown according to display screen die cavity inside weld situation carry out the repair welding operation, it is simple in structure, easy to use, can be widely used in having the repairing work of the inside weld of cavity structure.
Description of drawings
Fig. 1 is hollow stationary blade and die cavity thereof, weld seam schematic diagram;
Fig. 2 is the utility model device structure schematic diagram.
The specific embodiment
See Fig. 2, the utility model equipment comprises TIG welding gun, camera head 1 and display screen 2, and the lever of TIG welding gun is installed on extension rod 3, and ceramic protection cover 4 avris of TIG welding gun are equipped with camera head 1, and camera head 1 electricly connects with display screen 2.Camera head 1 is installed on the rear side of the ceramic protection cover 4 of TIG welding gun, and the angle β between camera head 4 and welding gun tungsten electrode axis direction is at 20 °～70 °, between the tungsten electrode of camera head 4 and welding gun is top is 10mm～60mm apart from d, and it is top that the image pickup scope of camera head 4 covers described tungsten electrode; Camera head is any in camera, endoscope head.In Fig. 2,5 is the data wire sleeve pipe of camera head, and the data wire of camera head extends back and electricly connects with display screen 2 along extension rod 3 by this sleeve pipe; 6 is tungsten electrode; 7 is insulator cap; 8 for being installed on the camera head signal of TIG welding gun ceramic protection cover front side.
