Specifically, when the sleeve rod 27 is turned downward, a shorter height difference is formed between the bottom of the sleeve rod and the top of the vertical rod 17, and the height difference is 0.1mm to 5mm.
The counterweight unloading unit 3 is arranged on the other side of the test unit 1 and is used for unloading the counterweight 6, the counterweight unloading unit 3 comprises a fourth linear mechanism 31 which is vertically arranged, a third rotating motor 32 which is vertically arranged is arranged at the sliding end of the counterweight unloading unit, a rotating plate 33 which is matched with the backing plate 18 is arranged at one end of an output shaft of the third rotating motor 32, and specifically, the rotating plate 33 is matched with the extension part of the backing plate 18.
In the present embodiment, the first linear mechanism 11 and the fourth linear mechanism 31 each use a rodless linear cylinder, and the second linear mechanism 21 and the third linear mechanism 22 each use a uniaxial linear cylinder.
The working mode is as follows:
firstly, one end of the cross rod 15, where the vertical rod 17 is located, is lifted up by the first rotating motor 14, a scratch pin 5 with a qualified state is assembled, then a new test board 4 with a coating is fixed on the bottom plate 12 by the board clamp 13, the cross rod 15 is adjusted to be horizontal by the first rotating motor 14, at the moment, the bottom of the scratch pin 5 is just contacted with the top surface of the coating of the test board 4, and when the test board 4 slides, the friction force generated by the scratch pin 5 is just 0N.
In the initial state, all the electromagnetic coils 25 are energized.
Next, loading is started from the smallest weight 6, specifically, the position of the second rotating motor 23 is moved by the horizontal moving assembly so that the loop bar 27 where the smallest weight 6 is located right above the matching with the vertical bar 17 when being rotated downward, then the loop bar 27 is rotated downward by the second rotating motor 23, the electromagnetic coil 25 matching with the smallest weight 6 is deenergized, the weight 6 falls onto the backing plate 18, and the assembly is completed, at which time the rotating plate 24 can be removed.
