Description

Technical Field

[0001] The utility model relates to the technical field of bushing size measurement, in particular to a bushing fast automatic size measurement device. Background Art

[0002] A bushing is an annular component used to reduce friction, protect parts or achieve specific functions. It can reduce direct contact between two relatively moving parts, thereby reducing friction and wear. In some applications, the bushing also acts as a seal to prevent liquid or gas leakage, or isolate different media. If the bushing is used in precision instruments, the size of the bushing has strict accuracy requirements. It is usually necessary to measure the size of the bushing during processing and production.

[0003] Common bushing measurement usually requires operators to cooperate with the inspection machine to perform multiple steps, which increases the operator's workload and reduces production efficiency. In addition, if deviation occurs when the bushing enters the inner side of the inspection device, it may affect the inspection results. Therefore, a bushing fast automatic size measurement device is proposed to address the above problems. Utility Model Content
