Abstract

The branch pipe intersecting line laying out instrument belongs to the field of machining technology. The branch pipe intersecting line laying out instrument includes a dial, a rotating disc, a rotating handle, a fastening blot, a fixing block, a fixing bolt, a fixed nut, a positioning steel sheet, a link rod, a movable nut, a central shaft and a steel rule connected together. The present invention can realize the fast laying out of branch pipe intersecting line in steel pipe structure and the fast laying out of connecting branch pipe in different forms of intersecting node, and has greatly raised work efficiency.

Description

technical field [0001] The invention relates to an instrument in the technical field of mechanical processing, in particular to a branch pipe intersecting line pay-off instrument. Background technique [0002] It is used for manual laying out of branch pipe intersecting lines of steel pipe structure, that is, drawing intersecting lines on the surface of branch pipes for branch pipe cutting. Although CNC pipe intersecting line cutting machines have been initially applied, most branch pipe cutting of steel pipe structures is still It is finished by hand-laying and hand-cutting. The traditional method of setting out intersecting lines of branch pipes is to first use the graphic method to stake out and mark lines on the plane sample material, cut the sample along the intersecting line, then wrap the sample on the branch pipe, and draw on the outer surface of the branch pipe along the edge of the sample. Out of the intersecting line. However, for complex space steel pipe struct...
