The counterweight loading unit 2 includes a horizontal movement assembly, and the horizontal movement assembly includes a second linear mechanism 21 arranged on a support, and one end of the output shaft A third linear mechanism 22 is provided, and one end of the output shaft of the third linear mechanism 22 is provided with a second rotating motor 23, and one end of the output shaft of the second rotating motor 23 is provided with a rotating plate 24, and the rotating plate 24 is provided with a plurality of electromagnetic coils 25, One side of the rotating plate 24 is provided with a plurality of brackets, the bracket is provided with a battery 26, the battery 26 matches and is electrically connected with the electromagnetic coil 25, and the electromagnetic coil 25 is provided with a bracket that matches the vertical bar 17 and is used to place the counterweight 6. Cover rod 27.

Specifically, when the sleeve rod 27 is turned downward, there is a short height difference between the bottom of the sleeve rod 27 and the top of the vertical rod 17, and the height difference is 0.1mm~5mm.

The counterweight unloading unit 3 is arranged on the other side of the test unit 1 for unloading the counterweight 6.

In this embodiment, both the first linear mechanism 11 and the fourth linear mechanism 31 use rodless linear cylinders, and the second linear mechanism 21 and the third linear mechanism 22 both use single-axis linear cylinders.

Way of working:

First, lift the end of the cross bar 15 with the vertical bar 17 by the first rotating motor 14, assemble a qualified stylus 5, and then fix a new coated test plate 4 on the base plate 12 through the plate clamp 13 Then the cross bar 15 is adjusted to the level by the first rotating motor 14. At this time, the bottom of the stylus 5 is just in contact with the coating top surface of the test plate 4, and when the test plate 4 slides, the friction force generated by the stylus 5 is just right. is 0N.

In the initial state, all the electromagnetic coils 25 are energized.
