Preferably; In the present embodiment; Also comprise a pair of sun wheel holder pouring weight 16, said sun wheel holder pouring weight 16 is arranged at respectively between two sun gears 14 and the said cutter cavity, and said sun wheel holder pouring weight 16 is fixedly connected with said connecting plate 23, said worm gear 20 respectively; Said sun wheel holder pouring weight 16 is provided with and two corresponding straight-line grooves of said two straight-line groove shapes, and said sun wheel holder pouring weight 16 has respectively and said worm gear 20 corresponding C shape of the mouth as one speaks breach.Through setting up a pair of C shape of the mouth as one speaks sun wheel holder pouring weight 16, can be so that pipe cutter be more stable when carrying out pipe cutting work.
In the present embodiment, said casing 7, said worm gear 20, said connecting plate 23, sun gear 14 and sun wheel holder pouring weight 16 all have corresponding C shape of the mouth as one speaks breach.This C shape of the mouth as one speaks breach supplies pipe cutter to move the center that is in said cutter cavity until pipe to be cut.Because the existence of C shape of the mouth as one speaks breach makes worm gear 20 and sun gear 14 can not carry out 360 degree rotations, in general, can only carry out the rotation smaller or equal to 270 degree.
Concrete, in the present embodiment, the diameter of pipe cutting to be cut is 8mm, and two movable cutter axle 25 whole diameters that have circular knife 24 are 20mm, and the fixed cutting tool axle 17 whole diameters that have circular knife are 20mm; The modulus of worm gear 20 is 2, and the number of teeth is 75; The diameter of five back shafts is 8mm, and the axle center of back shaft is 60mm from the centre distance of worm gear 20; Initiatively asteroid and driven asteroidal modulus are 0.5, and the number of teeth is 24 teeth; The modulus of sun gear 14 is 0.5, and the number of teeth is 216 teeth; Initiatively the modulus of major planet and driven major planet is 1, and the number of teeth is 57 teeth; The modulus of internal tooth is 1, and the number of teeth is 177 teeth.Certainly, device size can be according to the diameter variation of pipe cutting to be cut and corresponding adjustment, more than only illustrate.
Before managing cutting, pipe to be cut generally is in tension, and it can not rotate and be in stretching inactive state, and the automatic pipe cutter method for using of the C shape of the mouth as one speaks of the present invention specifically comprises the steps:
At first, the automatic pipe cutter of the C shape of the mouth as one speaks of present embodiment is moved horizontally, be in the position to be cut at pipe cutter center up to pipe.
Then, drive worm screws 9 through motor 10 and rotate, worm screw 9 drives worm gears 20 and rotates, and makes the cutter cavity unitary rotation that worm gear 20 and connecting plate 23 constitute.And said worm gear 20 and worm screw 9 gear motions can play decelerating effect.
Then, the worm gear 20 of rotation can drive initiatively mafor planet gear 11 and initiatively small planetary gear 12 rotations; Big initiatively planetary gear rotates in gear ring; All the other driven mafor planet gears 18 are done accompany movement in gear ring, initiatively small planetary gear 12 drives 14 rotations of corresponding sun gear, and all the other driven small planetary gears 19 are done accompany movement; Thereby; Worm gear 20 can be used as the sun gear 14 that planet carrier drives both sides and rotates, and thus, the capsule track groove 141 that is positioned at the straight-line groove 201,231 and the circular trough 202,232 of worm gear 20 and connecting plate 23 and is positioned at two sun gears 14 can rotate accordingly; The acting in conjunction of straight-line groove 201,231 and capsule track groove 141 can be adjusted the direct of travel of movable blade assembly, makes movable blade assembly and fixed cutting tool assembly cooperate feed and the cutting work accomplished smoothly.
Said motor 10 drives said worm screw 9 motions, and said worm screw 9 drives said worm gear 20 and rotates.Because said some planetary gear sets are set up on the corresponding connecting plate 23; That is to say that connecting plate 23 is provided with some back shafts that are used to support said some planetary gear sets; Because being fixedly connected with said worm gear 20, said connecting plate 23 constitutes the cutter cavity again; Therefore, worm gear 20 has played the effect of planet carrier simultaneously.The rotation of worm gear 20; Drive initiatively mafor planet gear 11 and active small planetary gear 12 simultaneously; Big initiatively planetary gear rotates in gear ring, and all the other driven mafor planet gears 18 are done accompany movement at gear ring, and initiatively mafor planet gear 11 plays spacing effect with driven mafor planet gear 18.
Embodiment 2
See also Fig. 6 a-Fig. 6 b, wherein, Fig. 6 a is the structural representation of the sun gear of embodiment 2; Fig. 6 b is the C-C cutaway view of Fig. 6 a.
The difference of present embodiment and embodiment 1 is; Said movable blade assembly is the movable cutter axle that has circular knife; One end of said movable cutter axle is arranged in the corresponding capsule track groove 141 ' of respective straight wire casing and corresponding sun gear 14 ' of said worm gear successively, and the other end is arranged in the corresponding capsule track groove 141 ' of respective straight wire casing and corresponding sun gear 14 ' of said connecting plate successively; Said dead knife assembly is the fixed cutting tool axle that has circular knife, and the two ends of said fixed cutting tool axle are arranged in respectively in the respective circular groove of said worm gear and said connecting plate.Because the movable cutter axle need pass through straight-line groove and capsule track groove 141 simultaneously, therefore, the capsule track groove 141 ' of present embodiment with respect to the capsule track groove of embodiment 1 more near the center of circle of worm gear or connecting plate.So present embodiment is compared with embodiment 1, though saved two slide block posts and two connecting rods, make structure simple relatively, can cause that feed is too fast, cutting effect is undesirable, when tubing is softer, easy deformation.
In sum, the automatic pipe cutter of the C shape of the mouth as one speaks of the present invention is in its center when pipe cutter moves until pipe to be cut; The motor-driven pipe cutter rotates to an angle; Automatically pipe is cut off, therefore, have automatic cutting, do not have assorted bits, the indeformable effect of otch; Can alleviate working strength of workers, effectively enhance productivity.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, belong within the scope of claim of the present invention and equivalent technologies thereof if of the present invention these are revised with modification, then the present invention also is intended to comprise these changes and modification interior.
