The spiral welded pipe positioning assembly 03 comprises a base 031, a first bracket 032, a second bracket 033, a first roller shaft 034 and a second roller shaft 035.

The base 031 may be connected to any one of the X-direction displacement adjustment mechanism 011, the Y-direction displacement adjustment mechanism 012, and the Z-direction displacement adjustment mechanism 013, or may not be connected to the X-direction displacement adjustment mechanism 011, the Y-direction displacement adjustment mechanism 012, and the Z-direction displacement adjustment mechanism 013.

For example, when the base 031 is connected to any one of the X-direction displacement adjustment mechanism 011, the Y-direction displacement adjustment mechanism 012 and the Z-direction displacement adjustment mechanism 013, the displacement adjustment assembly 01 and the spiral welded pipe positioning assembly 03 are integrated, which can improve the strength of the spiral welded pipe cutting apparatus, and also can make the spiral welded pipe cutting apparatus more convenient to use and the degree of matching between the assemblies higher.

For example, when the base 031 is not connected to the X-direction displacement adjustment mechanism 011, the Y-direction displacement adjustment mechanism 012, or the Z-direction displacement adjustment mechanism 013, the displacement adjustment assembly 01 and the helical weld pipe positioning assembly 03 are two independent assemblies. When the spiral welding pipe cutting device is used, the spiral welding pipe positioning assembly 03 is fixedly placed, the placing position of the displacement adjusting assembly 01 is determined according to the placing position of the spiral welding pipe positioning assembly 03, and finally the gun head of the cutting gun is aligned to the cutting line of the spiral welding pipe placed on the spiral welding pipe positioning assembly 03 by adjusting the displacement adjusting assembly 01. Because displacement adjustment subassembly 01 and spiral welded pipe locating component 03 are two independent subassemblies, consequently, displacement adjustment subassembly 01 and spiral welded pipe locating component 03 can be placed as required wantonly to spiral welded pipe cutting device's use flexibility has been improved.

It should be noted that the first bracket 032 is a component for clamping the first roller shaft 034, and the first bracket 032 includes two brackets, one of the two brackets is connected to the end face of one corner of the base 031, the other bracket is connected to the end face of the other corner of the base 031, and a connecting line between the two brackets and a midpoint of a connecting face of the base 031 is parallel to a long side of the base 031. The shape, the size homogeneous phase of two branchs frame all are provided with the through-hole on two branchs frame, and first roller 034 can pass these two through-holes card and establish on first support 032. The material of first support 032 can be carbon steel or alloy steel, and first support 032 is higher, and the external diameter of the first roller 034 that can block and establish is also big more, the embodiment of the utility model provides a do not specifically limit to this. In addition, the shape, size, and material of second support 033 and first support 032 are the same, second support 033 also includes two branch framves, the line that the midpoint of the face of being connected of a branch frame and base 031 in second support 033 and the midpoint of the face of being connected of base 031 of a branch frame in first support 032 is parallel to the broadside of base 031, the line that the midpoint of the face of being connected of two branch frames and base 031 in second support 033 is parallel to the long side of base 031, second support 033 is used for card to establish second roller 035.

Furthermore, in some possible implementations, the first roller 034 can be fixedly engaged with the first bracket 032 and the second roller 035 can be fixedly engaged with the second bracket 033, such that, in use, the spiral welded tube is manually rotated by a technician to effect cutting of the spiral welded tube. In other possible implementations, the first roller 034 is engaged with the first bracket 032 and can rotate relative to the first bracket 032, and the second roller 035 is engaged with the second bracket 033 and can rotate relative to the second bracket 033. Like this, when first roller 034 and second roller 035 rotated, alright drive place the spiral welded pipe synchronous rotation on first roller 034 and second roller 035, and, because the spiral welded pipe when rotating with first roller 034 and second roller 035 in step, can reduce the frictional force between spiral welded pipe and first roller 034 and spiral welded pipe and the second roller 035, consequently, when first roller 034 can rotate for first support 032, second roller 035 can rotate for second support 033, can avoid the danger because of the electric spark that the spiral welded pipe rotated and produced.

Optionally, the first rack 032 is fixedly connected to the base 031, the second rack 033 is movably connected to the base 031, and the second rack 033 is capable of moving along the base 031 relative to the first rack 032.

Specifically, when two branch brackets in the second support 033 are movably connected with the base 031 through slide rails, slide rails may be respectively arranged at positions of connection surfaces of the two branch brackets in the second support 033 and the base 031, the two branch brackets are respectively connected with the slide rails, and the two branch brackets are moved on the slide rails through displacement adjustment methods such as a lead screw, a rack gear or a roller, so as to realize a function that the second support 033 moves along the base 031 relative to the first support 032; when two branch framves in second support 033 and base 031 are through the mode and the base 031 swing joint that remove the face, can set up a plane that can remove on base 031, this plane can move on base 031 through displacement adjustment modes such as lead screw, rack and pinion, it is fixed with two branch framves with removing the face to when removing the face and removing base 031 for first support 032, realize the function that second support 033 removed for first support 032 along base 031.

In addition, it should be noted that, because base 031, first support 032 and first roller 034 all have certain height, when the spiral welded pipe was placed at first roller 034 and second roller 035, supporting platform 014 was greater than the height of base 031 in the displacement range of direction of height, the height of first support 032 and the sum of the external diameter of first roller 034 to make the burning torch can cut the spiral welded pipe in bigger within range, obtain the sample that the shape is abundanter. For example, when the Z direction is a height direction, the movable distance of the supporting platform 014 in the Z direction may be made larger than the sum of the height of the base 031, the height of the first bracket 032, and the outer diameter of the first roller shaft 034.
