To achieve these goals; Technical scheme of the present invention is: small-bore pipeline groove processing method; It is characterized in that: the magnetic-type pipe cutter is fixed on the base support; After small-bore pipeline to be processed used the pipeline jig clamping that is connected with rotating shaft,, by the burning torch that is arranged on the magnetic-type pipe cutter on the angle regulator small-bore pipeline is carried out flame cutting processing groove simultaneously with the magnetic force wheel drive rotating shaft rotation of magnetic-type pipe cutter.
Realize the small-bore pipeline chamfering device of said method, it comprises the magnetic-type pipe cutter, it is characterized in that: the magnetic-type pipe cutter is fixed on the base support, and the magnetic force wheel of magnetic-type pipe cutter contacts with rotating shaft; The burning torch of magnetic-type pipe cutter is arranged on the angle regulator, and angle regulator is arranged on the base support; Be fixed with clutch shaft bearing seat, second bearing block on the base support, the left end of rotating shaft is fixedly connected with pipeline jig, and the right-hand member of rotating shaft is linked to each other with the clutch shaft bearing seat by clutch shaft bearing, and the right part of rotating shaft is linked to each other with second bearing block by second bearing; The small-bore pipeline that the pipeline jig clamping is to be processed, burning torch are positioned at the top of small-bore pipeline to be processed.
Said rotating shaft is three sections ladder pipes that the hollow steel pipe welding forms, and the diameter of intermediate hollow steel pipe is greater than the diameter of the hollow steel pipe at two ends.
Said small-bore pipeline vial road diameter phi≤108mm.
The present invention fixes the magnetic-type pipe cutter; Let the magnetic force wheel of magnetic-type pipe cutter rotate together with small-bore pipeline to be processed with the driven rotary axle; Automatically process pipeline has overcome the difficult shortcoming of processing small-bore pipeline of magnetic-type pipe cutter, high efficiency; Simultaneously because small-bore pipeline and magnetic force wheel relative fixed on axis direction to be processed guaranteed machining accuracy (quality is good).Apparatus structure is simple and practical, and is with low cost, easy to operate.This method and device can be processed the small-bore pipeline groove easily.

The specific embodiment
In order to understand the present invention better, below in conjunction with accompanying drawing most preferred embodiment of the present invention is described, referring to Fig. 1 to Fig. 3:
Small-bore pipeline groove processing method; Magnetic-type pipe cutter 4 is fixed on the base support 1; After pipeline jig 6 clampings that small-bore pipeline to be processed 10 usefulness are connected with rotating shaft 3; (can adopt existing product with the magnetic-type pipe cutter; Like Shanghai China prestige magnetic-type pipe cutter) 4 magnetic force wheel 7 driven in rotation axles, 3 rotations (small-bore pipeline 10 is along with rotation), carry out flame cutting processing groove by 8 pairs of small-bore pipelines of the burning torch that is arranged on the magnetic-type pipe cutter 4 on the angle regulator 5 10 simultaneously.
Realize the small-bore pipeline chamfering device of said method; It comprises base support 1, clutch shaft bearing seat 2, rotating shaft 3, magnetic-type pipe cutter 4, angle regulator 5, pipeline jig 6, second bearing block 9;: base support 1 is fixed on the basis, ground; Be fixed with clutch shaft bearing seat 2, second bearing block 9 on the base support 1, the left end of rotating shaft 3 is fixedly connected (like welding) with pipeline jig 6, and the right-hand member of rotating shaft 3 is linked to each other with clutch shaft bearing seat 2 by clutch shaft bearing; The right part of rotating shaft 3 is by second bearing link to each other with second bearing block 9 (be that rotating shaft 3 can rotate, pipeline jig 6, small-bore pipeline 10 are along with rotation); Magnetic-type pipe cutter 4 is fixed on the base support 1, and the magnetic force wheel 7 of magnetic-type pipe cutter 4 contact with rotating shaft 3 (3 rotations of the magnetic force wheel of magnetic-type pipe cutter 47 driven in rotation axles); The burning torch 8 of magnetic-type pipe cutter 4 is arranged on (angle regulator can be adopted existing version, to regulate bevel angle) on the angle regulator 5, and angle regulator 5 is arranged on the base support 1; The small-bore pipeline 10 that pipeline jig 6 clampings are to be processed, burning torch 8 is positioned at the top of small-bore pipeline to be processed 10.
Said rotating shaft 3 is three sections ladder pipes that the hollow steel pipe welding forms, and the diameter of intermediate hollow steel pipe is greater than the diameter of the hollow steel pipe at two ends.For the quality that alleviates rotating shaft 3 to reduce the driving moment of driven in rotation axle 3 rotations; Rotating shaft 3 is three sections ladder pipes that the hollow steel pipe welding forms; Because the middle part of rotating shaft 3 is the force part; So the diameter of intermediate hollow steel pipe is greater than the diameter of the hollow steel pipe at two ends, rotating shaft 3 is selected to adopt the Q345 steel pipe, and suction is bigger mutually with magnet owing to the Q345 material.
Said pipeline jig is a chuck structure, and chuck is fixedly connected on the left end of rotating shaft 3 and is provided with one heart, and claw is used for the clamping small-bore pipeline.
Use of the present invention is: pipeline jig 6 clampings that small-bore pipeline 10 usefulness to be processed are connected with rotating shaft 3; And make pipeline and chuck coaxial as far as possible; The burning torch 8 and the angle distance of small-bore pipeline 10 to be processed are all adjusted, started magnetic-type pipe cutter 4, magnetic force wheel 7 driven in rotation axles 3 are together with small-bore pipeline to be processed 10 rotations; Open burning torch 8, carry out the groove operations.
Also can burning torch 8 be unloaded from angle regulator 5, clamping semi-automatic welding mouth carries out welding sequence on angle regulator 5, and welding efficiency is high, quality is good.Can realize multiple function.
Above disclosedly be merely preferred embodiments of the present invention, can not limit the present invention's interest field certainly with this, the equivalence of therefore doing according to claim of the present invention changes, and still belongs to protection scope of the present invention.
