Description

{Universal Checking Fixture for Measuring the Press Products}

More particularly, the present invention relates to a general-purpose inspection tool for three-dimensional measurement of a press-formed article, which is capable of moving the measurement reference point of the inspection tool according to the press- The present invention relates to a general-purpose inspection apparatus.

The automobile parts produced by press working generally have larger deformation amount than the parts produced through cutting and grinding, such as bending, and the end faces or pierced holes are rough and sharp. In many cases, the press-formed article itself has a complex shape rather than a flat surface.

In order to confirm the quality of these press-processed articles, various inspections and measurements are carried out on the press-processed articles. Korean Patent No. 10-1531444 (Surface Quality Inspection Method for Press-processed Products) and Korean Utility Model No. 20-0255514 (Flatness Measuring Apparatus for Pressed Water)

Therefore, when the three-dimensional measurement is performed with only the press part itself, errors occur frequently in the measurement due to the uncertainty of the reference point of the part.

In order to compensate for this, a conventional Checking Fixture corresponding to 1: 1 press parts was manufactured and precisely machined reference points were used for Coordinate Measuring. The use of such a dedicated inspection tool is a necessary method for ensuring the reliability of measurement, but it is time-consuming, costly, and complicated to manufacture a dedicated inspection tool for a large number of manufactured parts.
