Abstract
The invention relates to a high-precision workpiece fillet detecting method. The high-precision workpiece fillet detecting method is characterized by comprising the following steps of measuring a fillet outline graph of a workpiece by using a tool; extending right-angled sides of the workpiece until the right-angled sides are intersected according to the outline graph; determining a value (X), a value (Y), a value (r) and a value (R); drawing circles which are in different specifications and are tangential to a vertical line and a horizontal line according to a fillet region of the workpiece; and determining that the workpiece is qualified when the value (X), the value (Y), the value (r) and the value (R) are in fillet allowance. X is the maximum size of the distance from a point of a fillet to the vertical line, Y is the maximum size of the distance from the point of the fillet to the horizontal line, the radius of the drawn maximum circle is R, and the area of the drawn minimum circle is r. By the workpiece fillet detecting method, detailed measurement data can be provided, and reliable information can be provided for workpiece correction or equipment debugging; the workpiece fillet detecting method is accurate in detection; and a work fixture which is used in follow-up machining can be protected effectively.
Description
Technical field
The workpiece rounding detection method of workpiece sensing technical field of the present invention, particularly a kind of high-precision requirement.
Background technology
After rounding processing, its fillet size is the project of a more difficult detection always, if this rounding has high-precision technical requirement simultaneously, then can have a huge impact workpieces in subsequent crudy.As shown in Figure 1, existing detection scheme generally adopts determine one section of circular arc at 3, determines rounding size with this arc size.Because each selected point is different, cause measuring error comparatively large, more obvious when especially rounding is irregular.
Summary of the invention
The present invention is directed to the problems referred to above; there is provided a kind of workpiece rounding detection method, object is the size detection after can being applied to the processing of workpiece rounding, judges whether workpiece reaches technical requirement; ensure that workpiece meets following process condition, protect the safety of follow-up frock clamp.
For this reason, the present invention takes following technical scheme, a kind of workpiece rounding detection method, it is characterized in that the rounding contour pattern by instrument measuring workpieces, extending its right-angle side according to contour pattern is formed crossing, determine that X, Y, R are little, large four values of R, wherein X is the full-size of the point on rounding to perpendicular line, and Y is that point on rounding is to horizontal full-size; According to the interval at workpiece rounding place, draw the circle of different size, justify requirement and perpendicular line and horizontal line tangent, the maximum radius of a circle wherein drawn is that R is large, the smallest circle area drawn is that R is little, when X, Y, R are little, these four values are all namely qualified in rounding tolerance greatly for R.
The present invention utilizes the concept being similar to form tolerance (Line contour degree), is 3 sizes determining one section of circular arc, splits into 4 related datas, and judge rounding with these 4 data results by rounding.It is qualified that 4 measurement data are all in rounding tolerance, and X and Y data difference is the smaller the better simultaneously, and R is little the smaller the better with the large data difference of R.
The present invention has the following advantages:
1, more detailed measurement data can be provided, for workpiece correction or equipment debugging provide authentic communication;
2, detect accurately, effectively protect the frock clamp that following process uses.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of existing detection method
Fig. 2 is the schematic diagram that workpiece rounding of the present invention determines X and Y value.
Fig. 3 is the schematic diagram that workpiece rounding of the present invention determines that R is little and R is large.
Embodiment
Below in conjunction with specific embodiment, set forth the present invention further.
A kind of workpiece rounding detection method as shown in Figure 2, first use the contour pattern of contourgraph measuring workpieces rounding, extending its right-angle side according to contour pattern is formed crossing, determine that X, Y, R are little, large four values of R, wherein X is the full-size of the point on rounding to perpendicular line, and Y is that point on rounding is to horizontal full-size.
As shown in Figure 3, according to the interval at workpiece rounding place, perform drawing command, the circle of different size is drawn by circle (tangent, tangent, radius), justify requirement and perpendicular line and horizontal line tangent, the maximum radius of a circle wherein drawn is that R is large, and the smallest circle area drawn is that R is little.
The present invention utilizes the concept being similar to form tolerance (Line contour degree), is 3 sizes determining one section of circular arc, splits into 4 related datas, and judge rounding with these 4 data results by rounding.It is qualified that 4 measurement data are all in rounding tolerance, and X and Y data difference is the smaller the better simultaneously, and R is little the smaller the better with the large data difference of R.
Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
Claims (1)
1. a workpiece rounding detection method, it is characterized in that the rounding contour pattern by contourgraph measuring workpieces, extending its right-angle side according to contour pattern is formed crossing, determine that X, Y, R are little, large four values of R, wherein X is the full-size of the point on rounding to perpendicular line, and Y is that point on rounding is to horizontal full-size; According to the interval at workpiece rounding place, draw the circle of different size, justify requirement and perpendicular line and horizontal line tangent, the maximum radius of a circle wherein drawn is that R is large, the smallest circle area drawn is that R is little, when X, Y, R are little, these four values are all namely qualified in rounding tolerance greatly for R.
