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 bend pipe welding guns, referring to accompanying drawing 1 and accompanying drawing 2, in figure: welding torch clamping mechanism 1, adjusting rod 2, gear fixed mount 3, rotating shaft 4, gear are fixedly connected with pipe 5, circuit stationary pipes 6, reinforced support 7, gear-box 8, reducing motor 9, driving gear 10, centre wheel 11, gyroscope wheel 12, fast pulley 13, planetary gear 14, sun gear 15, support 16, bearing 17, connecting rod 18, bolster 20, the second bolster 21, workpiece 22.
In the present embodiment, gear-box 8 is placed on ground, driving gear 10 in gear-box 8 is connected with the reducing motor 9 that is placed in gear-box 8 outsides, driving gear 10 is meshed with centre wheel 11, driving gear 10 drives centre wheel 11 to rotate around central axis 0-0, on centre wheel 11, by rotating shaft 4, planetary gear 14 is housed, planetary gear 14 is meshed with sun gear 15, planetary gear 14 is also rotation (sun gear 15 maintains static) in the time that the axis 0 '-O ' work of sun gear 15 revolves round the sun, and axes O-O and axis 0 '-O ' is located on the same line.
Both center hole sizes of centre wheel 11 and sun gear 15 can make welding wire pass from centre, rotating shaft 4 outer cover be equipped with gear be fixedly connected with pipe 5(gear be fixedly connected with between pipe 5 and rotating shaft 4 leave enough spaces), the two ends that gear is fixedly connected with pipe 6 are connected with the side end face of gear fixed support 3 and centre wheel 2 respectively, gear is fixedly connected with on pipe 5 support 16 is housed, in support 16, rolling bearing is housed, rolling bearing 17 is sleeved on the two ends of circuit stationary pipes 6; The length of circuit stationary pipes 6 is less than gear and is fixedly connected with the length of managing 5; The front end of gear fixed support 3 connects welding torch clamping mechanism 1.
Gyroscope wheel 12 is also housed in rotating shaft 4, and gyroscope wheel 12 is identical with the structure of planetary gear 14, and gyroscope wheel 12 is meshed with fast pulley 13, and fast pulley 13 coaxially arranges with centre wheel 11; Gyroscope wheel 12 is done the gyration (fast pulley 13 maintains static) of the double rotation of revolution around fast pulley 13, fast pulley 13 is identical with the structure of sun gear 15.
Planetary gear 14 is contained on gear fixed support 3 by rotating shaft 4 and bearing, and sun gear 15 is integral structure with bolster 20, and bolster 20 is contained on gear fixed support 3 by bearing.
