In the actual production process, the important dimensional features of auto parts need to be extracted and detected by coordinate measuring instrument. The measuring bracket can assist CMM to precisely locate the automobile product and complete the detailed measurement of specific position. Gage testing stent, is generally designed and manufactured according to the body coordinate system. The positioning of reference should be consistent with requirements of GD & T drawings; It must also contain the reference plane or reference hole used to establish and test the accuracy of measurement bracket. Measuring brackets can make it possible to measure all the part data reasonably on the basis of valid product drawings and CAD data. The CMM can also be used for calibration and qualification of measuring brackets.

For automotive fixture test support, it can be divided into dimensional accuracy of test stent and quality appearance of test carrier, or it is available to achieve such two functions in a set of bracket. Compared with auto fixture, the production cycle of test bracket is shorter with the higher product detectable accuracy. It is mainly composed of three parts: - framework and base, body, as well function parts(including quick chuck, dowel pin, etc.) ). After the measuring stent is completed by CNC machining, the product needs to be placed on the measurement bracket by CMM to measure in detail. The production of Measurement stent, is usually metal processing, its surface can be sprayed or oxidized. For some gages that can not be directly placed on the three-coordinate detection, measuring bracket can help to complete the precise detection of special structure or small components. Similar with the car seized, Beijing Kingco has processed measuring brackets also equipped with positioning pins, locking pins, operating instructions, coordinate 100 grid, nameplate and other accessories.

The main function of measurement stand is to position and properly support the role, while trying to facilitate the three-coordinate measurement, avoiding interference or Inconvenient measurement. If the customer really needs the test function, it can be properly increased on the measuring stand.
