Round pipe end surface lineation machine

Abstract

The invention discloses a round pipe end surface lineation machine. The round pipe end surface lineation machine consists of a turning plate, a main ruler, a secondary ruler, a lineation needle and a fastening screw; when a center line is drawn, the inner side of the turning plate is tangential to the side surface of a cylinder or a round pipe; the main ruler is tightly bonded on the end surface of the cylinder or the round pipe; and as the axis of the lineation needle mounted on the secondary ruler is intersected with the angle line of the turning plate, the secondary ruler can be pushed to draw the center line on the end surface of the cylinder or the round pipe. When a concentric circle is drawn, the inner side of the turning plate is tangential to the side surface of the cylinder or the round pipe; the main ruler is tightly bonded on the end surface of the cylinder or the round pipe; the diameter of an outer circle is measured by the main ruler and the secondary ruler; the secondary ruler is shifted according to the radius of the drawn circle to enable the lineation needle to locate in the position of the circle to be drawn; the fastening screw is tightened to relatively fix the secondary ruler with the main ruler; the lineation needle rotates to enable the needle tip to contact with the end surface of the cylinder or the round pipe; and the lineation machine and the cylinder or the round pipe relatively rotate to draw the requested circle on the end surface. The round pipe end surface lineation machine can used for conveniently, quickly and precisely drawing the center line and the concentric circle on the end surface of the cylinder or the round pipe.

Description

[0001] Field [0002] The invention belongs to a scribing tool, in particular to a round pipe end surface scriber for marking diameters or concentric circles on the end surface of a round pipe. Background technique [0003] At present, for the processed round pipe, if you want to draw a diameter line on the end face or find out the center of the circle, you need to place the axis of the cylinder on the V-shaped fixture of the square box along the horizontal direction and clamp it with a height marking ruler. After measuring and calculating with the caliper, draw a center line after determining the height value of the center of the circle on the height marking ruler; to draw the center line, you need to rotate the workpiece at a certain angle and then draw a center line, use two The intersection of the centerlines to determine the center of the end face. If the processed workpiece is in the shape of a round tube, if you want to draw a concentric circle on its end face, you nee...
