[0035] The moving arm 32 is retracted in the fixed arm 31, the fixed arm 31 on the support 2 is moved above and below the steel plate through the slide rail base 1, so that the triangulation scanner 4 on the moving arm 32 is located at the upper and lower edges of the steel plate; the thickness of the edge of the steel plate is detected by the triangulation scanner 4; the fixed arm 31 above and below the steel plate is continuously moved by the support 2, and the thickness of the middle part of the steel plate is detected by moving to the middle part of the steel plate; when the triangulation scanner 4 on the moving arm 32 cannot be located in the middle part of the steel plate, the motor 33 is started to control the moving arm 32 to extend, and the triangulation scanner 4 is moved to the middle part of the steel plate to detect the thickness of the middle part of the steel plate; after the detection is completed, the moving arm 32 is retracted, and the fixed arm 31 is brought back to the original position by the support 2.
[0036] The limit guide rail 311 is arranged on the inner wall of the fixed arm 31. Through the limit guide rail 311, it can be ensured that the front end of the moving arm 32 will deviate downward due to gravity during the movement of the moving arm 32 on the fixed arm 31.

[0048] The bracket 2 drives the fixed arm 31 to move on the slide rail base 1, and the triangulation scanner 4 on the moving arm 32 moves to the position of the middle part of the steel plate, when the bracket 2 moves to the limit position of the slide rail base 1, the position of the triangulation scanner 4 still cannot be located in the middle part of the steel plate, at this time, the motor 33 is started, the motor 33 drives the driving gear 34 to rotate and transmits power to the driven gear 35, and the driving gear 34 and the driven gear 35 rotate at the same time to drive the two transmission gears 36 meshed with them to rotate, and the two transmission gears 36 rotate in opposite directions, which will drive the rotating lead screw 37 to rotate, in the process of rotating, the sliding nut seat 321 on the rotating lead screw 37 drives the moving arm 32 to move outward, so as to realize that the moving arms 32 above and below the steel plate extend at the same time, and move to the middle part of the steel plate with the triangulation scanner 4, and measure the thickness of the middle part of the steel plate, so as to complete the detection of the thickness of the middle part of the steel plate.
