Description

Technical Field

[0001] The utility model relates to the technical field of three-coordinate measurement, in particular to an L-shaped probe system. Background Art

[0002] A three-coordinate measuring machine is an instrument that can measure geometric shapes, lengths, and circular divisions within a hexahedral space. It is also called a three-coordinate measuring machine or a three-coordinate measuring bed. A three-coordinate measuring machine can also be defined as "a detector that can move in three directions and can move on three mutually perpendicular guide rails. This detector transmits signals in contact or non-contact ways. The displacement measurement system of the three axes (such as a grating ruler) calculates the various points (x, y, z) of the workpiece and various functional measurements through a data processor or computer." The measurement functions of a three-coordinate measuring machine should include dimensional accuracy, positioning accuracy, geometric accuracy, and contour accuracy. The dimensional measurement of workpieces is one of the most commonly used measurement functions of a three-coordinate measuring machine, such as the dimensional measurement of the inner diameter of a workpiece.

[0003] In the prior art, when measuring features in the opposite direction of the three-dimensional Z axis or inner features, a cross-shaped probe system is generally used. However, when the cross-shaped probe system is used to measure features with shapes on the edge of the measuring hole, it will collide with or interfere with the probe system, which requires destroying the product to remove the excess interference parts for normal measurement, increasing costs and reducing work efficiency.
