The inner side of the clamping plate 360 ​​is provided with multiple slots 361 of different inner diameters. The multiple slots 361 of different inner diameters can clamp and fix workpieces of different sizes, thereby further enhancing the practicality of the device. The inner wall of the slot 361 is provided with a protective pad. The protective pad is made of rubber and provides protection for the clamped and fixed workpiece.

[0030] Combination Figures 1-3 This embodiment of a resistance shaft testing adjustment centering clamping device is used as follows: After the device is placed in the designated position, it is fixed by bolts 102. The second motor 310 is started to drive the second lead screw 320 to rotate, which drives the two clamping plates 360 to move closer to each other, thereby clamping and fixing the workpiece. After clamping and fixing, the first motor 210 is started, which drives the first lead screw 220 to rotate, thereby driving the slider 230 and the sliding plate 240 to adjust and move, so as to adjust the position of the clamped workpiece, so that the workpiece is in a centered position for convenient subsequent testing. The multiple slots 361 with different inner diameters allow the device to clamp and fix workpieces of different sizes, thereby further enhancing the practicality of the device. The protective pads set in the slots 361 protect the clamped and fixed workpiece, preventing the inner wall of the clamping plate 360 ​​from directly contacting the workpiece and causing wear.
