Abstract
The utility model relates to a rotary mechanism of pipeline cold cut cutting mill, it is including drive arrangement, card formula annular frame, card formula rotary teeth rim plate, drive arrangement fixes on calorie lateral wall of formula annular frame, drive arrangement's the epaxial gear of output and the external gear engagement of card formula rotary teeth rim plate, the track inner chamber of card formula rotary teeth rim plate is equipped with inboard V type guide slot and the outside V type guide slot with the axle center with rotation center, and card formula annular frame is equipped with inboard eccentric roller train and the eccentric roller train in the outside respectively on the inboard V type guide slot that corresponds and outside V type guide slot position, the axle center equipartition of inboard eccentric roller train and each gyro wheel of outside off -centre roller train on the circumference of the correspondence with the axle center, the wheel of each gyro wheel is surperficial and V type guide slot meshes. The utility model discloses an orbital setting in, outward, the gyro wheel is good all the time with the contact of V type guide slot, and the eccentric gyro wheel that sets up provides convenient not only for installation card formula rotary teeth rim plate, can adjust the clearance between gyro wheel and the V type guide slot through adjusting off -centre simultaneously.
Description
Technical field
This utility model is related to a kind of cutting, welding equipment, more particularly, to a kind of rotating mechanism of pipeline cold cut cutting mill.
Background technology
In the installation of tubing or maintenance construction, need the port to steel pipe to carry out otch, so as to pipeline docking,
Or increase three way cock or valve is installed, the locational uncertainty of these operations causes very big difficulty to construction, in order to solve
Certainly cause using manual operations, cutting that otch is coarse, irregular phenomenon occurs in work progress, by the cutting of high speed rotation
Cutterhead is cut.But, effect is unsatisfactory, and its main weak point is that the track structure of rotation is unreasonable, cutting knife during cutting,
Or the jerk value of cutter is big, and vicious cycle is more produced after path wear, crudy can not be guaranteed.
The content of the invention
The purpose of this utility model is to provide a kind of simple structure, reasonable stress, energy for prior art weak point
A kind of rotating mechanism of the pipeline cold cut cutting mill of steady operating.
The purpose of this utility model is realized by following measures：A kind of rotating mechanism of pipeline cold cut cutting mill, it is wrapped
Driving means, cassette annular support, cassette rotary teeth wheel disc are included, driving means are fixed on the side wall of cassette annular support,
Gear on the output shaft of driving means is engaged with the external gear of cassette rotary teeth wheel disc, it is characterised in that the cassette rotation
The track inner chamber of rotating disk disk is provided with the inner side V-type guide groove and outside V-type guide groove concentric with center of rotation, cassette annular support
Inner side eccentric roller group and outside eccentric roller group are respectively equipped with corresponding inner side V-type guide groove and outside V-type guide groove position,
The axle center of each roller of inner side eccentric roller group and outside eccentric roller group is distributed on concentric corresponding circumference, each roller
Wheel surface engage with V-type guide groove.
The roller of the inner side eccentric roller group and the roller of outside eccentric roller group are single arranged in a crossed manner.
Compared with prior art, employ the utility model proposes a kind of pipeline cold cut cutting mill rotating mechanism, have
Following advantage：1) this product is by the outer, setting of inner orbit, no matter pipeline cold cut cutting mill is arranged on which type of position, roller
Contact with V-type guide groove is good all the time, and cassette rotary teeth wheel disc will not be shaken when operating, and not only increase quality and prolong
Service life is grown；2) eccentric roller that this product is arranged not only is provided conveniently, while right to installation cassette rotary teeth wheel disc
The gap between roller and V-type guide groove can be adjusted in the roller of abrasion by adjusting bias.
Description of the drawings
Fig. 1 be the utility model proposes one embodiment structural representation.
Fig. 2 is that Fig. 1 implements exception, the schematic diagram of interior eccentric roller arrangement.
Specific embodiment
Specific embodiment is elaborated below in conjunction with the accompanying drawings：Fig. 1～Fig. 2 shows a reality of the present utility model
Apply example.In figure, a kind of rotating mechanism of pipeline cold cut cutting mill, it is included：Annular support 2, the cassette rotation of driving means 1, cassette
Rotating disk disk 3, driving means 1 are fixed on the side wall of cassette annular support 2, the gear and card on the output shaft of driving means 1
The external gear engagement of formula rotary teeth wheel disc 3, the track inner chamber of the cassette rotary teeth wheel disc 3 is provided with concentric with center of rotation
Inner side V-type guide groove 31 and outside V-type guide groove 32, cassette annular support 2 is led in corresponding inner side V-type guide groove 31 and outside V-type
It is respectively equipped with inner side eccentric roller group 41 and outside eccentric roller group 42 on the position of groove 32, inner side eccentric roller group 41 and outer lateral deviation
The axle center of each roller of heart roller group 42 is distributed on concentric corresponding circumference, the wheel surface of each roller and V-type guide groove are nibbled
Close.The roller of the inner side eccentric roller group of the present embodiment and the roller of outside eccentric roller group are single arranged in a crossed manner, may also be employed
Two one group of mode is arranged in a crossed manner.
Embodiments presented above is not constituted to restriction of the present utility model, and those skilled in the art in the art are in institute
Various modifications are made in the range of attached claim or is changed in protection domain.
