Technical Field

[0001] This utility model relates to the field of sheet metal inspection technology, specifically a sheet metal inspection device with laser calibration function. Background Technology

[0002] Sheet metal parts are widely used in machinery, electronics, automobiles and other fields. Especially in the production of network switch chassis, the chassis serves as the mounting carrier and external protection structure for the internal components of the switch. Its dimensional accuracy directly affects the assembly compatibility of the components.

[0003] Currently, traditional sheet metal inspection devices mostly use fixed benchmarks. When changing the product model to be inspected, the benchmark structure needs to be readjusted, which is cumbersome and time-consuming, and has poor adaptability. Some devices can only achieve single-axis or dual-axis inspection and cannot fully capture the three-dimensional dimensional deviations of the product. In view of this, we propose a sheet metal inspection device with laser calibration function. Utility Model Content
