Problems solved by technology

At present, many automobile manufacturers generally use manual assembly when assembling the main nut of the wheel hub. After testing the pre-tightening force of the bearing, when it is found that the pre-tightening force does not meet the requirements, then tighten or loosen the main nut. Repeated operations are required for the first assembly of the hub, which is time-consuming and labor-intensive, and mechanical automation cannot be realized, which wastes labor costs

Description

technical field [0001] The invention relates to the field of assembly of automobile parts, in particular to a mechanically automated wheel hub main nut tightening and bearing pretightening force measuring machine and a use method thereof. Background technique [0002] With the continuous development of industry, the automobile industry has also developed rapidly, and people's requirements for automobile quality are also constantly improving, especially for the assembly of the main nut of the automobile wheel hub and the requirements for the preload of the bearing. At present, many automobile manufacturers generally use manual assembly when assembling the main nut of the wheel hub. After testing the pre-tightening force of the bearing, when it is found that the pre-tightening force does not meet the requirements, then tighten or loosen the main nut. When the wheel hub is assembled for the first time, repeated operations are required, which is time-consuming and labor-intensi...
