Description

Technical Field

[0001] The utility model relates to the technical field of three-coordinate measuring instruments, in particular to a three-coordinate measuring instrument which can provide stable support. Background Art

[0002] A three-coordinate measuring instrument is an instrument that can measure geometric shapes, lengths, and circumference indexes within a hexahedral space. It is also called a three-coordinate measuring machine or a three-coordinate measuring bed. A three-coordinate measuring instrument is one of the most effective methods for measuring and obtaining dimensional data, because it can replace a variety of surface measurement tools and expensive combination gauges, and reduce the time required for complex measurement tasks from hours to minutes, which is an effect that other instruments cannot achieve.

[0003] Traditional three-dimensional coordinate measuring machines are generally equipped with a foot cup at each of the four corners of the bottom for support and positioning. On the one hand, when the ground is not flat enough, it is necessary to manually adjust the height of each foot cup for leveling. The adjustment process is very cumbersome, resulting in extremely low adjustment efficiency. On the other hand, since the contact area between the foot cup and the ground is very small and the supporting force is insufficient, and the table top of the three-dimensional coordinate measuring machine is generally a heavy granite slab, the foot cup is prone to slight deformation after long-term use and needs to be leveled again.

[0004] In summary, the supporting structure of the existing three-coordinate measuring machine needs to be improved. Utility Model Content
