[0027] The control device 4 includes a fixed sliding seat 43. At the center of the rear end face of the fixed sliding seat 43, a measuring probe 42 is fixedly arranged, and at the center of the upper end face of the fixed sliding seat 43, a servo motor 41 is fixedly arranged. At the output end of the servo motor 41, a transmission gear 44 is fixedly arranged, and at the inner end face of the fixed sliding seat 43 near the opening, a guiding slider 45 is arranged.

[0028] The guiding slider 45 is adapted to the guiding chute 2, and the arc-shaped guide rail 1 and the annular guide rail 3 are slidably clamped with the control device 4 through the adaptation of the guiding slider 45 to the guiding chute 2, which can effectively improve the stability of the subsequent displacement of the control device 4 outside the arc-shaped guide rail 1 and the annular guide rail 3.

[0029] Both the arc-shaped guide rail 1 and the annular guide rail 3 are meshed and connected with the transmission gear 44. The meshing connection of the transmission gear 44 with the arc-shaped guide rail 1 and the annular guide rail 3 can provide sufficient guiding stability for the subsequent displacement of the fixed sliding seat 43 outside the arc-shaped guide rail 1 and the annular guide rail 3.

[0030] The driving gear 6 is meshed and connected with the inside of the fixed gear ring 9.

At the same time, the transmission gear 44 can drive the fixed sliding seat 43 and the measuring probe 42 to rotate around the annular guide rail 3 through meshing with the annular guide rail 3. At this time, the measuring probe 42 can perform a lateral scanning operation on the workpiece at the center of its rotation circle in all directions. After the lateral scanning is completed, then the servo motor 41 above the arc-shaped guide rail 1 is started. At this time, the servo motor 41 can drive the fixed sliding seat 43 and the measuring probe 42 to slide up and down outside the arc-shaped guide rail 1 through the transmission gear 44, and the measuring probe 42 can perform an up and down scanning detection on the side of the workpiece. At the same time, the reduction motor 7 can drive the fixed gear ring 9 and the annular guide rail 3 to rotate synchronously and intermittently through the driving gear 6, so that the arc-shaped guide rail 1 can rotate synchronously and intermittently with the annular guide rail 3, thereby facilitating the subsequent measuring probe 42 above the arc-shaped guide rail 1 to scan the workpiece from various lateral angles.
