Detailed Description

The technical solution of the present invention will be described in further detail with reference to the accompanying drawings and preferred embodiments.

As shown in fig. 1, fig. 2, fig. 3 and fig. 5, the buffer tank head welding tool in this embodiment includes: base 1 is provided with frame 2 on base 1, and drive shaft 3 passes through bearing seat group 31 horizontal support and sets up in frame 2, is fixed with chuck 4 at 3 front ends of drive shaft, thereby drive shaft 3 is rotated by drive arrangement drive, drive chuck 4 at the uniform velocity. Set up two landing legs 5 on the base in chuck 4 the place ahead, two landing legs 5 distribute in the left and right both sides of base 1, all are provided with supporting roller 6 at 5 tops of every landing leg, and every supporting roller 6's supporting axle all supports in corresponding landing leg 5 tops through support frame 7. One end of the buffer tank 10 is clamped in the jaws 41 of the chuck 4, and the barrel of the buffer tank 10 is placed on the two supporting rollers 6. The chuck 4 described in this embodiment adopts a three-jaw self-centering chuck with external jaws, and in the actual use process, a protective layer, such as a rubber protective pad, may be further disposed on the clamping surface of each jaw 41, and the protective layer is disposed to protect the surface of the buffer tank 10, so as to prevent the buffer tank 10 from being damaged by the clamping of the clamping surface.

As shown in fig. 3 and 4, in the present embodiment, a supporting leg adjusting groove 11 is respectively formed on the base 1 corresponding to the bottom of each supporting leg 5, and the length direction of each supporting leg adjusting groove 11 is set in the front-back direction; the bottom of each supporting leg 5 is locked in the corresponding supporting leg adjusting groove 11 through at least two bolts 7, and after the bolts 7 are loosened, each supporting leg 5 can slide back and forth along the corresponding supporting leg adjusting groove 11, so that the distance between the two supporting rollers 6 and the chuck 4 is adjusted.
