The specific embodiment

As shown in Figure 1 and Figure 2, channel bend circular arc automatic gas cutting machine of the present utility model comprises pedestal 1, rotating shaft 2, motor 3, gear reduction unit 4, disk 5, locating

piece

6,13, bearing support 7, locating support 8, cutter 9, height adjustment mechanism 10, circular arc automatic ranging mechanism 11; Wherein, rotating shaft 2 is installed on the pedestal 1, and both sides have guide groove 21; Motor 3 links by gear reduction unit 4 and rotating shaft 2; Disk 5 is sheathed to be connected on the rotating shaft 2, have locating slot 51 on the disk 5, and locating piece 13 is complementary with it; Guide groove 21 is that trapezoidal cross section structure, locating slot 51 are T type cross section structure; Locating piece 6 shapes and rotating shaft 2 guide grooves 21 are complementary, and are located in 5 times rotating shaft guide grooves 21 of disk; Bearing support 7 is fixed on the pedestal 1; Locating support 8 is fixed on the bearing support 7; Cutter 9 is fixed on the locating support 8, and cutter 9 is a cutting torch; Height adjustment mechanism 10 is arranged on the pedestal 1, comprises the power transmission shaft 101, the regulating wheel 102 that are arranged in the body 15; Regulating wheel 102 cooperates for worm gear, worm screw with power transmission shaft 101, and power transmission shaft 101 two ends are provided with bearing 103,104, and by end cap 105,106 sealings; Described bearing support 7 hypomeres cooperate with power transmission shaft 101 gears; Circular arc spacing mechanism 11 comprises screw mandrel 111, spring 112, adjusting nut 113, movable block 114, adjusting screw(rod) 115 and contact 116, connecting rod 117; Screw mandrel 111 1 ends are fixed in locating support 7, and the other end is movably connected on bearing support 7, and by adjusting nut 113 lockings; Spring 112 is sheathed on the screw mandrel of 8 of locating support 7 and bearing supports; Movable block 114 is located on the locating support 8, and is movably connected on the locating support 8 by adjusting screw(rod) 115; This contact 116 is fixed on the locating support 8 by fixed support 118 and connecting rod 117.
