For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of pipe is cut the clamping device in machine, comprise guide rail, on guide rail, slide and be provided with two fixtures in opposite directions, described fixture comprises the support being slidably arranged on guide rail, in support, rotates and is provided with hollow spindle, and support is stretched out in one end of main shaft, and this end is provided with ring flange, on ring flange, be provided with the claw for swelling pipe that a circle can radially move respectively along ring flange.
On described ring flange, be positioned on that side side of claw and be provided with a circle guide pad, on guide pad, be provided with rounded guide rod of arranging, ring flange is positioned at the corresponding pilot hole that offers on the position of guide pad inner side, in pilot hole, be inserted with respectively guide post, the homonymy of ring flange and guide pad is provided with pressing plate, ring flange, between guide pad and pressing plate three, form a cavity, on guide post, be fixed with guide block, guide post is arranged in cavity, between guide pad and guide block, be provided with spring, one side of guide block is stretched out cavity, and claw is fixed on this side of guide block, on support, be provided with cylinder, the piston rod of cylinder extends in ring flange passing in main shaft, and the end of piston rod is fixed with truncated cone-shaped pulling block, in pilot hole, be respectively arranged with ball, ball between guide post and pulling block and simultaneously and the end of guide post and the contacts side surfaces of pulling block.
On described ring flange, be fixed with U-shaped protective sleeve, an end of pulling block is positioned at protective sleeve.
The invention has the beneficial effects as follows: utilize the mode fixing tube of swelling, can avoid making its distortion in fixing tube.
Accompanying drawing explanation
Fig. 1 is the structural representation that pipe of the present invention is cut the clamping device in machine;
Fig. 2 be in Fig. 1 A to view.
In figure: 1, guide rail, 2, support, 3, bearing, 4, main shaft, 5, ring flange, 6, claw; 7, guide pad, 8, guide rod, 9, pilot hole, 10, guide post, 11, pressing plate, 12, cavity; 13, guide block, 14, spring, 15, cylinder, 16, pulling block, 17, ball, 18, protective sleeve.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiment of the invention scheme in detail.
As shown in Figure 1, pipe of the present invention is cut the clamping device in machine, comprise guide rail 1, on guide rail 1, slide and be provided with two fixtures in opposite directions, described fixture comprises the support 2 being slidably arranged on guide rail 1, in support 2, by bearing 3, is rotated and is provided with hollow spindle 4, support 2 is stretched out in one end of main shaft 4, and this end is provided with ring flange 5, on ring flange 5, be provided with the claw 6 for swelling pipe that a circle can radially move respectively along ring flange 5---shown in Fig. 2, gapped between adjacent claw 6.On claw 6, be provided with a plurality of steps, thereby can put the pipe of sizes.Introduce a kind of simple in structure, ring flange that jaw adjustment is quick and easy and the syndeton of claw below.On described ring flange 5, be positioned on that side side of claw 6 and be provided with a circle guide pad 7, on guide pad 7, be provided with the rounded guide rod of arranging 8, ring flange 5 is positioned at the corresponding pilot hole 9 that offers on the position of guide pad 7 inner sides, the interior guide post 10 that is inserted with respectively of pilot hole 9, the homonymy of ring flange 5 and guide pad 7 is provided with pressing plate 11, ring flange 5, between guide pad 7 and pressing plate 11 threes, form a cavity 12, on guide post 10, be fixed with guide block 13, guide post 10 is arranged in cavity 12, between guide pad 7 and guide block 13, be provided with spring 14, spring 14 is enclosed within guide post 10 and guide rod 8.One side of guide block 13 is stretched out cavity 12, and claw 6 is fixed on this side of guide block 13.On support 2, be provided with cylinder 15, the piston rod of cylinder 15 extends in ring flange 5 passing in main shaft, and the end of piston rod is fixed with truncated cone-shaped pulling block 16, in pilot hole 9, be respectively arranged with ball 17, ball 17 is between guide post 10 and pulling block 16 and contact with the end of guide post 10 and the side (inclined-plane) of pulling block 16 simultaneously, and in figure, the roundlet end face on the left side of pulling block 16 or the right do not affect working effect.In order to prevent that ball 17 and pulling block 16 from being lost flexibility by contamination by dust, on described ring flange 5, be fixed with U-shaped protective sleeve 18, an end of pulling block 16 is positioned at protective sleeve 18.
The course of work of the present invention is: as shown in Figure 1, now, claw 6 is in contraction state, the two ends of pipe are enclosed within respectively in the respective step of claw 6, then drive the piston rod of cylinder 15 to shrink, pulling block 16 moves to right under the effect of piston rod, because ball 17 is in pilot hole 9, therefore ball 17 radially outward moves along ring flange 5 under the effect on pulling block 16 inclined-planes, ball 17 promotes guide post 10 and outwards moves, guide post 10 drives guide block 13 outwards to move, thereby guide block 13 drives the outwards mobile claw 6 swelling pipes that utilize of claw 6---shown in Fig. 2, realize the fixing of pipe.When unclamping pipe, drive the piston rod of cylinder 15 to move to right, claw 6, guide block 13, guide post 10 and ball 17 reset under the effect of spring 14.Utilize the mode fixing tube of swelling, can avoid making its distortion in fixing tube.
