The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.

To shown in Figure 4, the present invention is fixed on through mount pad 4 on the mobile working head of numerical control cutting machine like Fig. 1, and mount pad 4 tops are fixed with servomotor 1 and reductor 2 through regulating seat 3, and reductor 2 output shafts are provided with driving gear 5.The cantilever front end of mount pad 4 is equipped with gear shaft 7 through bearing 8, and the fluted disc portion of gear shaft 7 is meshed with driving gear 5.Triple channel rotation gas connection 6 is installed in gear shaft 7 tops; The below utilizes straight pin that the horizontal plane of runing rest 9 is installed; The vertical plane bottom of runing rest 9 is provided with two parallel line slideways 10, and upper slide rest 12 usefulness screws are installed on the slide block of line slideway 10, and the support column 13 usefulness screws that universal ball ball 14 is installed in the bottom are installed in upper slide rest 12 belows; The arc 20 usefulness screws that angle scale is housed are installed in upper slide rest 12 downsides, and handle 11 is installed in below the runing rest 9 through screw thread.

Three roller shafts 18 fall " article " font with two of tops, one of below; Be fixed on the swivel plate 19 with nut respectively; Three V-arrangement cross section rollers 15 are installed on three roller shafts 18 through bearing 16 and spacer 17 respectively; Wherein two rollers 15 of top contact with the extrados V-way of arc 20, and the roller 15 of below contacts with the intrados V-way of arc 20.Arc-shaped rack 22 usefulness screws are installed on the arc 20, and handwheel 25 is fixed on the swivel plate 19, and the axle of handwheel 25 is provided with the angle adjustment gear 23 with arc-shaped rack 22 engagements, and lock screw 26 is installed in swivel plate 19 upper ends and withstands angle adjustment gear 23.

Fixed clamp bar 21 on the swivel plate 19; Flame cutting torch 24 is installed in the other end of supporting rod 21; The cutting torch summit of flame cutting torch 24 is positioned on the central axis of gear shaft 7; Simultaneously the cutting torch summit also is positioned on same the horizontal linear with the center of circle of arc 20, and the central axis quadrature of this horizontal linear and gear shaft 7 also is positioned on the perpendicular; The lower vertex of universal ball ball 14 is positioned at above-mentioned horizontal linear below.

During real work: in the time need not carrying out the workpiece grooves cutting; Unclamp lock screw 26; Adjusting handle 25 makes the flame cutting torch 24 on the swivel plate 19 be in the upright position of scale on the arc 20, tightens lock screw 26, and this device can carry out normal Numerical control cutting.When carrying out workpiece, needs decide groove when cutting; Unclamp lock screw 26; Adjusting handle 25 makes the flame cutting torch 24 on the swivel plate 19 be in the angle position of scale on the arc 20 (general maximum angle is positive and negative 60 degree), tightens lock screw 26, the straight cuts that can carry out deciding groove this moment.And in cutting process, under the control of numerical control program, by servomotor 1 accurate the driving, through the gear pair engagement, control gear axle 7 rotates with runing rest 9 in real time, then can cut out circular groove or the curve slope of deciding groove.Through the up-down of adjusting upper slide rest 12 on line slideway 10 highly, and through handle 11 lock with adjusting.

Because the cutting torch top of flame cutting torch 24 of the present invention is consistent with the center of circle of arc 20; And the center of flame cutting torch 24 is consistent with the center of gear shaft 7; Make that the cutting center of flame cutting torch 24 is constant all the time, can guarantee that digital control system automatic time at work returns dress.Owing to adopted triple channel rotation gas connection 6; Make three road input channels of carrying cutting gas keep motionless in mount pad 4 upper ends; And three road output channels of the flame cutting torch 24 of gear shaft 7 bottoms can followed gear shaft 7 and rotated with runing rest 9, infinitely turn round and pipeline can not twine.The position of universal ball ball 14 of the present invention is below the home position of arc 20; Make the cutting torch top of flame cutting torch 24 can not run into cut workpiece all the time; And making that under the effect of universal ball ball 14 upper slide rest 12 fluctuates according to the unevenness of workpiece, protection flame cutting torch 24 carries out the groove cutting of deciding of arbitrary line or curve.

More than describing is to explanation of the present invention, is not that institute of the present invention restricted portion is referring to claim to the qualification of invention, and under the situation of spirit of the present invention, the present invention can do any type of modification.
