Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts measurement, and more specifically to a precise flexible quick-release switching connection block. Background Art

[0002] Most automobile OEMs and parts manufacturers use three-coordinate measuring machines for automatic measurement of parts. Currently, the most widely used measurement platforms are the flexible sandwich substrate measurement platform and the Five measurement platform. The flexible sandwich substrate measurement platform uses a flexible sandwich substrate with a flexible measurement positioning support column and a special RPS positioning block for measurement, while the Five measurement platform uses a Five bottle support positioning block for measurement.

[0003] At present, with the rapid promotion of new flexible measurement tooling, more and more manufacturers are beginning to use flexible sandwich substrate measurement platforms, which are gradually replacing traditional Five measurement platforms. However, during the transition and switching stage of the measurement platform, it is necessary to face the problem of incompatibility of measurement positioning blocks used on different platforms. The current solution is that for new project parts, in addition to making special RPS positioning blocks for the new platform, an additional set of measurement positioning blocks dedicated to the traditional Five measurement platform must be customized to solve the problem of centralized measurement of the part on different measurement platforms.
