In the figure: the line drawing device comprises 1-transverse supporting rods, 2-elastic line drawing devices, 3-adjusting holes, 4-central supporting rods, 5-screws, 6-fastening nuts, 7-rectangular flat blocks, 8-line drawing pens, 9-cylinders and 10-springs.
Detailed Description
Referring to fig. 1-4, the utility model relates to a line drawing device for butt welding of round tubes, which is provided with a central support rod 4, the bottom of the central support rod is in a pointed shape, the upper part of the central support rod is provided with a transverse support rod 1, the transverse support rod and the central support rod are arranged in a mutually perpendicular way, and a strip-shaped adjusting hole 3 is arranged on the transverse support rod along the length direction of the rod; the line drawing device is characterized by further comprising an elastic line drawing device 2, wherein the upper portion of the elastic line drawing device is fixedly connected with the adjusting hole through a screw rod 5 and a fastening nut 6.
Furthermore, in the embodiment, the elastic line drawing device comprises a cylinder 9, the upper part of the cylinder is fixedly connected with a corresponding adjusting hole, the upper end of the cylinder is closed, and the lower end of the cylinder is open, a spring 10 is arranged in the cylinder, the lower end of the spring is fixedly connected with a line drawing pen 8, and the pen point of the line drawing pen faces downwards and extends out of the lower end opening of the cylinder; the height of the lower end of the cylinder body is consistent with that of the lower end of the central support rod.
Further, in this embodiment the upper end of barrel is equipped with the flat piece 7 of rectangle, and this flat piece of rectangle and regulation hole fastening connection adopt this kind of structure setting, can make the barrel not take place not hard up swing as far as possible.
Further, in this embodiment, the central support rod is made of a square rod or a circular rod.
Furthermore, in this embodiment, the line drawing pen is a pencil or a marking pen, and it is convenient to select different line drawing pens for drawing lines on circular tubes made of different materials.
The utility model discloses the setting-out device is used for drawing the intersecting line that is used for the butt joint on the pipe outer wall, in the time of using, because the pipe diameter of butt joint is different, the intersecting line that so draws is also different, consequently just need adjust the interval between setting-out pen and the central support pole according to required earlier, confirm required radius (be the pipe radius promptly), then decide the most advanced of central support pole lower extreme on the pipe outer wall, at last like when using the compasses setting-out the line can, in the process of drawing a circle, the pipe outer wall belongs to the curved surface, and the setting-out pen makes the nib of setting-out pen draw on the pipe outer wall all the time under the spring action in the barrel, and then draw the intersecting line.
Adjusting the distance between the line drawing pen and the central support rod: and loosening the fastening nut, moving the screw to different positions, and after the screw is adjusted, tightening the fastening nut for fixing.
The utility model discloses overall structure design is simple practical, setting-out radius adjustment convenient and fast, and the operation is got up simply easily and is handed, provides convenience for subsequent trompil operation originally and welding operation.
