The aluminum roller online wear testing machine according to claim 6, characterized in that: The wear mechanism includes a friction rod inserted on the support tube, a return spring sleeved on the friction rod, a friction head arranged on the friction rod, a rotating shaft arranged in the support tube, a rotating rod arranged on the rotating shaft, a push rod 1 arranged on the rotating rod and connected to the push rod, and a push rod 2 arranged on the rotating rod and connected to the friction rod.

8. The aluminum roller online wear testing machine according to claim 7, characterized in that: When the pushing telescopic rod is extended upward, the arc-shaped support block is pushed to move above the friction head, so that the arc-shaped support block is used to place the aluminum roller, and the aluminum roller is aligned with the clamping groove. After the aluminum roller is clamped, the pushing telescopic rod is contracted downward, and the rotating rod pushes the friction head upward, so that the friction head moves to above the arc-shaped support block, so that the friction head supports the aluminum roller.

9. The aluminum roller online wear testing machine according to claim 8, characterized in that: The observation mechanism includes a support rod inserted on the frame and an in-situ wear mark measuring instrument arranged on the support rod. The support rod is used to move on the frame to adjust the observation position of the in-situ wear mark measuring instrument on the aluminum roller.

10. A friction test method based on the aluminum roller online wear tester according to claim 9, characterized in that: include: S1: the pushing telescopic rod moves upward, so that the arc-shaped support block moves above the friction head, and the heat-conducting rod is inserted into the eddy current heating wire; S2: hoisting and transporting the aluminum roller to the top of the frame, and then placing the aluminum roller on the arc-shaped support block so that the arc-shaped support plate provides a positioning base point: S3: the alignment telescopic rod drives the rotating ring to move, so that the two ends of the aluminum roller are inserted into the clamping groove, and the clamping telescopic rod clamps and fixes the aluminum roller; S4: The linear module drives the friction head to move to the position to be friction tested, and inserts the power supply head into the telescopic power supply hole, so that the eddy current heating wire and the electric heating wire are connected, and the eddy current heating wire is energized, so that the electric heating wire heats the aluminum roller, and the eddy current heating wire heats the heat conducting rod, thereby heating the friction head; S5: the pushing telescopic rod contracts, so that the friction head presses against the aluminum roller, and the rotating motor drives the aluminum roller to rotate, so that the friction head rubs on the aluminum roller; S6: Stop the aluminum roller from rotating and align the wear mark in-situ measuring instrument with the wear mark for observation.
