In summary, in the implementation process of the embodiment, when the wear resistance of the paint needs to be tested when the paint is subject to rolling friction, firstly, the board to be tested is placed in the placing tray 201 and fixed, and then the overturning plate 103 is overturned to point to the left direction, as shown in fig. 1, and at this time, the grinding wheel 111 is just attached to the upper surface of the board to be tested; then, the driving motor 113 is started to drive the grinding wheel 111 to roll reciprocally, so that rolling friction can be generated between the grinding wheel 111 and the board to be tested. When it is required to test the abrasion resistance of the paint when it is subjected to sliding friction, it is first required to control the movement of the inspection stage 200 to the right side position of the insertion groove 120 by using the displacement motor 121, and then pull the first handle 311 backward to draw the positioning post 308 away from the positioning hole 115 and rotate the turnover plate 103 to the right side position, as shown in fig. 2, it is noted that when the turnover plate 103 rotates, it is required to pull the second handle 413 backward to prevent the first bevel gear 407 from blocking the rotation of the mounting plate 106. When the turnover plate 103 rotates in place, the first bevel gear 407 and the second bevel gear 117 are meshed, and at this time, the grinding wheel 111 can be indirectly controlled to rotate through the driving motor 113, so that relative sliding friction is generated between the grinding wheel 111 and the plate to be tested, and the abrasion resistance of paint bearing the sliding friction is tested.
