The tightening mechanism includes an equipment stand 13, a movable moving grating 6, a plurality of tightening heads 7 for tightening, and a driving member 9 for driving the tightening head 7 to rotate. The driving member 9 and the tightening head 7 are both connected to the moving grating 6 and driven up and down by the moving grating 6. The workbench 1, positioning work, feeding mechanism, detection mechanism and tightening mechanism move in a circular trajectory under the control of the control system, and automatically tighten the assembly screws of the wheel hub and disc brake disc on the positioning tooling 2 in turn.

[0023] The structure is reasonably designed, with a high degree of automation and high assembly efficiency. It is only necessary to place the wheel hub and the disc brake disc on the corresponding positioning tooling 2, and move the rotatable workbench 1 to the position of the loading mechanism in sequence, and cooperate with the rotation of the positioning tooling 2 to pre-install multiple assembly screws in the assembly holes. After passing the inspection of the detection mechanism, it is moved to the assembly station, and multiple tightening heads 7 are tightened and rotated at the same time, so that the disc brake disc can be stably, firmly and reliably connected to the wheel hub.
