Abstract

The invention discloses a coordinate positioning angle rule, which consists of a longitudinal coordinate meter, a horizontal coordinate meter, a longitudinal vernier, a horizontal vernier and a fixed-point sleeve. Zero position ends of two straight scales with marks are butted to form the coordinate meter; a common point where the zero positions of the longitudinal coordinate meter and the horizontal coordinate meter intersect is taken as a positioning point, a trepan boring is formed by taking the positioning point as a center, and the trepan boring is provided with a sleeve for a marking pen; and then the verniers are arranged on the longitudinal coordinate meter and the horizontal coordinate meter respectively, a side of the vernier facing an intersection point is the zero position, and the zero position of the mark corresponds to the zero position of the coordinate meter. The coordinate positioning angle rule has the progressive advantages of quick position finding, exact positioning, convenient use, simple assembling and processing, and the like.

Description

A kind of coordinate setting angle square

Technical field

The invention belongs to the measurer technical field, relate to a kind of coordinate setting angle square.

Background technology

Up to now, continue to use always when hand-drawing and machining people be that the intersection point that ruler or angle square are measured ordinate and abscissa is located by the point sampling method on object plane, and the obtained some deviation of this method is bigger, and this is well-known in the industry; So giving needs the people of hand-drawing and five metals processing to bring very big inconvenience and helpless.In order to address this problem, I have invented a kind of coordinate setting angle square specially through for many years practice summary, bring work convenient and increase work efficiency can for largely the people that need hand-drawing and five metals processing industry.

Summary of the invention

The object of the present invention is to provide a kind of coordinate setting angle square, with its pointed structural design provide a new solution for improving above-mentioned existing problem, thereby help improving people's work efficient and guarantee product quality.

For achieving the above object, solution of the present invention is:

A kind of coordinate setting angle square is made up of ordinate chi, abscissa chi, vertical vernier, horizontal vernier and fixed point sleeve; At first with the zero-bit end of two rulers that indicate scale to being connected into coordinatometer, getting the common point that ordinate chi and abscissa chi zero-bit intersect is anchor point, is that a trepanning is opened at the center with this anchor point again, and the sleeve that one of configuration is used for marking pen on this trepanning; On ordinate chi and abscissa chi vernier is installed respectively then, vernier is a zero-bit towards the side of intersection point, and the zero-bit of its scale is corresponding with the zero-bit of coordinatometer.

During use, need only after the coordinate angle square raises the accurate longitudinal and transverse coordinate values that needs to fix a point also fixing, on object plane, determine a benchmark right angle (as the lower left corner on standard square plane) then, two vernier zero-bit sides with the coordinate setting angle square are stuck on the both sides of this reference angle again, like this, the mid point of abutment sleeve is the anchor point that we need look on the coordinate setting angle square.

After adopting said structure, the present invention has and looks for the position fast, and the location is accurate, and is easy to use, the simple progressive advantage that waits of assembling processing.
