The functions of the first driving device 15 are mainly two, one is to reduce the labor intensity of workers, and the other is to improve the detection precision. When the radial jump detection equipment provided by the embodiment of the application is used for detecting the drilling tool base body, the drilling tool base body can be placed at the designated position on the workbench 11, then the subsequent detection process can be automatically carried out after the connecting piece 14 is connected with the drilling tool base body, in the whole working process, a worker only needs to place the drilling tool base body and detach the drilling tool base body, and in the detaching process, the worker only needs to hold the drilling tool base body, so that the separation of the drilling tool base body and the connecting piece 14 can be realized.
In addition, the connection of the drill base to the connection member 14 can be made more accurate and consistent with the benefit of automation in the connection process.
The laser ranging sensor 16 is used for detecting the distance between the laser ranging sensor and the drilling tool base body, and the specific process is as follows, the laser ranging sensor 16 emits a beam of laser, the laser is sensed by the laser ranging sensor 16 after being reflected on the surface of the drilling tool base body, and then distance calculation is carried out in a pulse ranging or phase ranging mode.
