It should be noted that through such a setting, the sliding block 204 can stably move linearly inside the mechanical arm 202, thereby driving the self-adaptive detection assembly 3 to realize accurate position adjustment. This design not only improves the flexibility of the device, but also ensures that the sensor probe 3052 and the surface of the rod 4 maintain the best contact state, thereby efficiently and accurately measuring the surface coating thickness of the rod 4. In addition, the cavity structure of the mechanical arm 202 effectively reduces the overall weight while maintaining sufficient strength and stability.

It should be noted that through such a design, the sensor probe 3052 can be self-adaptively adjusted during the detection process, so as to ensure that it is in the best contact state with the surface of the rod member 4. The elastic effect of the spring 3054 enables the T-shaped fixed groove block 305 to flexibly slide on the plug screw 304, so as to be adjusted in real time according to the unevenness of the surface of the rod member 4. Such a design not only improves the detection accuracy, but also effectively avoids errors caused by improper human operation. In addition, the cooperation of the column groove block and the inner groove limits the position of the spring 3054, so that the working state of the spring 3054 is more stable.

At the same time, the second motor 203 in the vertical moving assembly 2 starts to operate, drives the lead screw 2022 to rotate, and then drives the sliding block 204 to controllably slide along the side sliding groove of the mechanical arm 202. The movement of the sliding block 204 enables the self-adaptive detection assembly 3 fixedly connected thereto to be accurately positioned to the detection area.

[0032] The sensor probe 3052 in the self-adaptive detection assembly 3 can automatically adjust the position according to the actual situation of the surface of the rod member 4 through the cooperation of the T-shaped fixed groove block 3051 and the spring 3054, so as to ensure that the sensor probe 3052 is in the best contact state with the surface coating of the rod member 4 during the detection process. The sensor probe 3052 measures the thickness of the surface coating of the rod member 4 in real time and feeds back the data to the detection control system.
