Description
Technical field
The present invention 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 to be driven substantially, and its structure chart is as shown in figure 1, because tooth
Transmission between wheel group needs power transmission shaft, and power transmission shaft must be straight, this require welding gun support loop bar must be straight, with because
It is to be limited by bend pipe internal diameter, cause gear at welding gun to do and will not be made too greatly, greatly limit the increase of H-number, Jin Er great
Limit greatly the size of built-up welding bend pipe.
Content of the invention
It is an object of the invention to overcoming the deficiency of prior art and providing in a kind of 90 degree of bend pipes being suitable for bigger specification
The built-up welding welding gun of wall welding.
The present invention adopts the following technical scheme that：
A kind of 90 degree of elbow internal wall built-up welding welding guns, including gear-box, motor, arc welding gun head, the sliding tooth on gear-box
Wheel be meshed with gear wheel, driving gear be connected with motor it is characterised in that：Gear wheel is contained in welding gun and supports on loop bar,
Welding gun supporting loop bar is in curved structure, and the tail end of curved structure is placed in 90 degree of bend pipes, and welding gun supports the front end of loop bar equipped with little
Travelling gear on gear housing, this travelling gear is meshed with little gear, and little gear is connected with small machine, described pinion stand
Equipped with arc welding gun head assembly on body.
Using technique scheme the present invention compared with prior art, can according to the different size of 90 degree of bend pipes enter rule
Lattice are adjusted, and can be suitable for the welding gun of 90 degree of elbow internal walls of bigger specification.
The present invention adopt preferred version be：
It is connected by bearing between travelling gear and little gear casing.
Welding gun supporting loop bar in curved structure tilts loop bar, parallel loop bar, rear end inclination by the horizontal loop bar in front end, front end
Loop bar and the horizontal loop bar of tail end are connected in sequence.
Travelling gear is located on same axis with gear wheel.
The centre of gyration of travelling gear is in hollow shape structure, equipped with arc welding gun head on the centre of gyration of this travelling gear.
Travelling gear is passed through screw and is connected with welding gun supporting loop bar.
Brief description
Fig. 1 is the structural representation of prior art.
Fig. 2 is the structural representation of the present invention.
Fig. 3 is the top view of pinion stand（A in Fig. 2 is to sectional view）.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment describe in detail the present invention：
A kind of 90 degree of elbow internal wall built-up welding welding guns, referring to accompanying drawing 2 to accompanying drawing 3, in figure：Motor 1, gear-box 2, driving
Gear 3, gear wheel 4, connecting shaft 5, welding gun support loop bar 6, the horizontal loop bar in front end 601, front end to tilt loop bar 602, parallel loop bar
603rd, rear end tilt loop bar 604, the horizontal loop bar of tail end 605, little gear casing 7, travelling gear 8, bearing 9, arc welding gun head assembly 10,
Little gear 11, small machine 12.
In the present embodiment, the driving gear 3 on gear-box 2 is meshed with gear wheel 4, and driving gear 3 is with motor 1 even
Connect, 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
In bend pipe, welding gun supports the front end of loop bar 6 equipped with the travelling gear 8 on little gear casing 7, this travelling gear 8 and little gear 11
It is meshed, little gear 11 is connected with small machine 12；Equipped with arc welding gun head assembly 10 on little gear casing 7.
It is connected by bearing 9 between travelling gear 8 and little gear casing 7.
Welding gun supporting loop bar 6 in curved structure tilts loop bar 602, parallel loop bar by the horizontal loop bar in front end 601, front end
603rd, rear end tilts loop bar 604 and the horizontal loop bar of tail end 605 is connected in sequence.
Travelling gear 8 is located on same axis with gear wheel 4.
The centre of gyration of travelling gear 8 is in hollow shape structure.
The excircle of travelling gear 8 is passed through screw and is connected with the horizontal loop bar of tail end 605 in welding gun supporting loop bar 6.
The length of end construction and 90 degree of bend pipes that the welding gun in curved structure supports loop bar 6 is adapted；Processing used
Cheng Zhong, the length at angle of inclination and 90 degree of bend pipes that rear end tilts loop bar 604 is adapted.
Driving gear 3 drives gear wheel 4 to rotate, and gear wheel 4 drives welding gun to support loop bar 6 to rotate（Welding gun supports loop bar 6
Velocity of rotation is harmonious with the velocity of rotation of workpiece, makes welding gun support loop bar 6 forever constant with the relative position of workpiece, it is to avoid
Interfere）, welding gun support loop bar 6 is connected with the travelling gear 8 of little gear casing 7, rotates together.Now, little gear casing 7
On small machine 12 drive little gear 11 to rotate, the coordination of its velocity of rotation and gear wheel 4 rotating speed phase（Speed is consistent, turns to phase
Instead）It is ensured that little gear casing 7 geo-stationary, now, in the front end of pinion stand casing 7, arc welding gun head assembly 10 is installed and can protect
Card welding gun geo-stationary.
The present embodiment, only needs to design a kind of adaptable welding gun according to the weldment of different size and supports loop bar 6 can expire
Sufficient welding requirements, the present embodiment is adapted to more specification of workpieces than prior art, substantially increases the applicable model of the present invention
Enclose.
