Description

Technical Field

[0001] The utility model relates to the technical field of three-coordinate measuring instruments, in particular to a measurement auxiliary structure for three-coordinate measuring instruments. Background Art

[0002] A three-dimensional coordinate measuring instrument, also known as a three-dimensional coordinate measuring machine or a three-dimensional coordinate measuring machine, is an instrument that can measure geometric shapes, lengths, and circumferential indexing within a hexahedral space. This device has a detector that moves in three directions and can move on three mutually perpendicular guides to transmit signals in a contact or non-contact manner. Through a data processor or computer, it can calculate each point (x, y, z) of the workpiece and various functional measurements.

[0003] Although the three-coordinate measuring machine has high measurement accuracy, it may be difficult to directly perform accurate measurement when facing some complex or irregularly shaped workpieces. In addition, since the shapes of some workpieces are not convenient for placement, in order to better measure the volume of the workpiece, the operator often spends a long time to place and fix it, which leads to longer measurement time and reduces the measurement efficiency of the workpiece. In order to solve the above problems, while facilitating the fixation and support of the workpiece to prevent it from moving and deforming during the measurement process, it is convenient for the operator to complete the placement and positioning of the workpiece more quickly and conveniently, reduce the adjustment and calibration time, thereby improving the accuracy and stability of the measurement and improving the workpiece detection efficiency. For this reason, we propose a measurement auxiliary structure for a three-coordinate measuring machine. Utility Model Content
