Abstract
Provided is a novel T-shaped eccentric ruler capable of highly-efficient determination of the center of a circle. The T-shaped ruler is provided with a bottom edge and a vertical edge. The vertical edge is perpendicular to the bottom edge. One end of the vertical edge is positioned on the eccentric position of the bottom edge. One side edge of the vertical edge is superposed with the perpendicular bisector of the bottom edge. Positioning projecting points are arranged on the bottom edge. The novel T-shaped eccentric ruler of the utility model allows the purpose of high-efficient determination of the center of a circle to be realized while enabling the precision to be guaranteed.
Description
Technical field
The utility model relates to a kind of surveying and mapping tool, is specifically related to the eccentric chi of T-shaped that a kind of novel ability high-level efficiency is confirmed the center of circle, is applicable to the flange of circular sheet material, the device in definite centers of circle such as illiteracy plate.
Background technology
The method in conventional definite center of circle is in people's actual production: adopt how much line to get 2 intersection points of handing over round straight line perpendicular bisector; Perhaps get the center when intersecting the circle full-scale reading with the iron chi; Two kinds of methods are like this confirmed the center of circle; Wherein how much line speed are slow, and the method for reading is because the manually-operated problem can only the convergence center of circle and can not guarantee accurately.
Summary of the invention
The utility model technical matters to be solved is: solve the problem that above-mentioned prior art exists, and the eccentric chi of the T-shaped that provides a kind of novel ability high-level efficiency to confirm the center of circle is issued to high efficiency purpose in the situation that guarantees precision.
The technical scheme that the utility model adopts is: make one the T-square with base and vertical edges; Vertical edges is perpendicular to the base; And vertical edges one end is positioned at the eccentric position on base, and a side of vertical edges overlaps with the perpendicular bisector on base, on the base, processes positioning convex point.
Principle of work:
The eccentric chi main body of the T-shaped of the utility model is close to working surface; Positioning convex point plays the role of positioning in scratching process; As: hold out against the circular arc edge with positioning convex point, along the perpendicular bisector line of the eccentric chi of T-shaped, the intersection point of any 2 diverse locations line is exactly the center of circle that workpiece need be confirmed.When hollow flange is used, need to assist with fritter stack pile sheet material to place position, place, the center of circle.
Therefore, the utility model is simple in structure, and is easy to use, and adaptability is good, and got rid of mismachining tolerance, directly provides the center of circle how much.Realized being issued to the purpose that high-level efficiency is confirmed the center of circle in the prerequisite that guarantees precision.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model principle of work synoptic diagram.
Among the figure, 1-eccentric chi main body, 2-base, 3-vertical edges, 4-perpendicular bisector,
5-positioning convex point, 6-center of circle.
Embodiment:
Referring to Fig. 1, Fig. 2, the eccentric chi main body 1 of the utility model is a T-square with base 2 and vertical edges 3, and vertical edges 3 is perpendicular to base 2; And vertical edges one end is positioned at the eccentric position on base; Vertical edges 3, the one of which side overlaps with the perpendicular bisector 4 on base, on the base, processes positioning convex point 5; Along the perpendicular bisector line of the eccentric chi of T-shaped, the intersection point of any two diverse locations line is exactly to need definite center of circle 6.
Claims (1)
1. a novel ability high-level efficiency is confirmed the eccentric chi of T-shaped in the center of circle; It is characterized in that: make one T-square with base and vertical edges; Vertical edges is positioned at the eccentric position on base perpendicular to base and vertical edges one end; One side of vertical edges overlaps with the perpendicular bisector on base, on the base, processes positioning convex point.
