Abstract
The utility model relates to the special equipment that is used for the pipeline cutting in a kind of pipeline welding engineering.The improvements of this multifunctional pipe cutting machine are that worm screw 7 is supported on dolly base plate 28 inside, and worm screw 7 connects with power shaft 21; Geometrical clamp bearing up pulley arm 11 is packed on the dolly base plate 28, and live splint bearing up pulley arm 4 also is installed on the dolly base plate 28; Described live splint bearing up pulley arm 4 is a hollow with the inside of geometrical clamp bearing up pulley arm 11, and driving flexible axle 3 runs through wherein; Install worm gear 8 on the described driving flexible axle 3, and driving pinch wheels 1 also is equipped with at its two ends; On live splint bearing up pulley arm 4, also be provided with self-locking mechanism 5.The grasp simple to operate, easy of this cutting machine, cut quality are stablized.And adopt inside and outside flexible axle to drive, and realized driven in synchronism, eliminated because the discontinuous characteristics of cutting that evolution brings have not only improved cut quality, also reduced working strength of workers, improved speed of application and welding efficiency.
Description
Technical field
The utility model relates to the special equipment that is used for the pipeline cutting in a kind of pipeline welding engineering.
Background technology
At present, be that the pipe cutter that the many companies of representative produce differs from one another with U.S. CRC-EVANS company abroad: some is to adopt thin stainless steel band as soft track, and some adopts hard track; Some is chain drive, and some is the internal gear transmission.Domesticly cutting the pipe cutter that tool etc. is produced as Zhejiang great-grand father department difficult to understand and Hua Wei, then all is to adopt the rigidity friction pulley to realize that by directly contacting with pipeline cutting walks, and basic structure and external product are very nearly the same.All there is the shortcoming that is difficult to overcome in they, and promptly cutting speed is low; Cut quality is poor, and cut surface is coarse unusually, terminal point is difficult to overlap, and need carry out secondary operations such as emery wheel processing; Adopt randomly located track, cutting track is difficult to control; Install and remove loaded down with trivial details etc.
Summary of the invention
Technical problem to be solved in the utility model just provides a kind of Multifunction pipe cutter, makes it be provided with inside and outside flexible shaft driving mechanism and inner flexible axle walking mechanism, can guarantee to cut carriage walking steadily, continuously, fast.
Technical problem to be solved in the utility model is realized by following technical scheme: this multifunctional pipe cutting machine, its improvements are that worm screw 7 is supported on dolly base plate 28 inside, and worm screw 7 connects with power shaft 21; Geometrical clamp bearing up pulley arm 11 is packed on the dolly base plate 28, and live splint bearing up pulley arm 4 also is installed on the dolly base plate 28; Described live splint bearing up pulley arm 4 is a hollow with the inside of geometrical clamp bearing up pulley arm 11, and driving flexible axle 3 runs through wherein; Install worm gear 8 on the described driving flexible axle 3, and driving pinch wheels 1 also is equipped with at its two ends; On live splint bearing up pulley arm 4, also be provided with self-locking mechanism 5.
Above-mentioned multifunctional pipe cutting machine, described live splint bearing up pulley arm 4 is crooked, and its quantity is at least two.
Above-mentioned multifunctional pipe cutting machine, described geometrical clamp bearing up pulley arm 11 is crooked, and its quantity is at least two.
Above-mentioned multifunctional pipe cutting machine, the quantity of described driving flexible axle 3 are at least two.
Above-mentioned multifunctional pipe cutting machine, the quantity of described driving pinch wheels 1 are at least four.
This multifunctional pipe cutting machine is in cutting process, and operating personnel drive the cutting dolly by outside flexible axle, and simple to operate, easy grasp, cut quality are stablized.And adopt inside and outside flexible axle to drive, and realized driven in synchronism, eliminated because the discontinuous characteristics of cutting that evolution brings have not only improved cut quality, also reduced working strength of workers, improved speed of application and welding efficiency.
Description of drawings
Fig. 1 is a main cutaway view of the present utility model;
Fig. 2 is a sectional view of the present utility model;
The structure diagram that Fig. 3 amplifies for automatic locking mechanism;
The structure diagram that Fig. 4 amplifies for the external drive flexible axle.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
See also Fig. 1 to shown in Figure 4, among the figure inner flexible axle synchronous drive mechanism mainly by four drive pinch wheels 1, four needle bearings 2, two internal drive flexible axles 3, two live splint bearing up pulley arms 4, spherical bearing 6, worm screw 7, two worm gears 8, radial ball bearing 9, bolt 10, two geometrical clamp bearing up pulley arms 11 are formed.Worm screw 7 is supported on dolly base plate 28 inside.Geometrical clamp bearing up pulley arm 11 is packed on the dolly base plate 28 by bolt 10, and live splint bearing up pulley arm 4 also is installed on the dolly base plate 28 by spherical bearing 6.Live splint bearing up pulley arm 4 is a hollow with the inside of geometrical clamp bearing up pulley arm 11, drives flexible axle 3 and runs through wherein.Drive on the flexible axle 3 and install worm gear 8, and driving pinch wheels 1 also is equipped with at the two ends of driving flexible axle 3.Worm screw 7 drives two worm gears 8, drives pinch wheels 1 rotation fully synchronously to guarantee four.Also be provided with oil filler point 13 and mounting hole 14 on dolly base plate 28, mounting hole 14 can be realized cutting dolly and adapt to different calibers.
On live splint bearing up pulley arm 4, also be provided with self-locking mechanism 5.Self-locking mechanism 5 is mainly formed by adjusting nut 15, adjustment cover 16, angular adjustment axle 17, self-locking spring 18, connecting rod 19 and handle 20.Whole cutting dolly wanted outer flexible axle driving just can walk when handle 20 closed.The clamping force that drives pinch wheels 1 realizes jointly by self-locking spring 18 and adjustment nut 15.Because of live splint bearing up pulley arm 4 has used spherical bearing 6, can realize whole cutting dolly fast assembling-disassembling.
The whole driving moment of this multifunctional pipe cutting machine mainly is made up of power shaft 21, interface axle 22, adapter sleeve 23, protective jacket 24, rubber sleeve 25, spring driving shaft 26 and exterior protection spring 27 input of external drive flexible axle.Power shaft 21 connects by joint 12 with worm screw 7.The external drive flexible axle can forward and reversely rotate, and realizes forward and reverse walking of cutting dolly.The length of external drive flexible axle satisfies the cutting dolly can be around Guan Yizhou, has overcome the shortcoming that cutting machine in the past must the operator be followed the dolly commentaries on classics.Simultaneously, the interface of external drive flexible axle can be general with the interface of stepper motor decelerator, realized driving manually and automatically and exchanging.
