In the above-mentioned implementation process, be provided with first locating hole 32 on the three location platform 21 respectively, simultaneously, three location platform 21 respectively with base plate 1 fixed connection for the position of first locating hole 32 is immovable, simultaneously, radium to fender 3 cuts the mode and realizes on machining precision detection device, and after the radium cut mode ended, the workman directly detected fender 3 directly to the trompil position, need not dismantle fender 3, in order to improve work efficiency.

In some embodiments, a plurality of second support blocks 8 are provided at the outer circumference of the inspection station 5 for supporting the fender 3.

In the above-mentioned realization process, the periphery interval that detects platform 5 is provided with a plurality of second supporting shoes 8, fixes fender 3, avoids fender 3 to produce when processing man-hour and rocks to improve fender 3's stability.
