The assembly line comprises an inner ring transmission measuring device, an outer ring transmission measuring device, tray conveyor lines, a trap device, a vibration inspecting device, a windage inspecting device and a grease infusion inspecting device, wherein the inner ring transmission measuring device, theouter ring transmission measuring device are connected with the trap device through the tray conveyor lines; the trap device is connected with the vibration inspecting device through a conveyor line,the vibration inspecting device is connected with the windage inspecting device through a sliding table, the tail end of the sliding table is provided with a charging mechanism, and the charging mechanism is connected with the windage inspecting device through an output line; and the front faces of the vibration inspecting device and the windage inspecting device are provided with a transporting device respectively. The invention can finish all the assembly working procedures of the automobile first-generation hub bearing, and realizes automatically inspecting each working procedure and automatically setting parameters; and a PLC is utilized to automatically control the operation of an executing mechanism according to the procedures, thus realizing accurate control and ensuring assembly quality.

Description

technical field [0001] The invention relates to an assembly device for the first-generation hub bearing of automobiles, belonging to the technical field of hub bearing manufacturing. Background technique [0002] The hub bearings used in automobiles are divided into first, second and third generations according to their structural composition, and the second and third generations are also called hub units. The first generation hub bearing is a double-row angular contact ball bearing or double-row tapered roller bearing with integral outer ring and back-to-back combination of inner ring. Its specific structure is as follows: figure 1 As shown, it includes outer ring 01, steel ball 02, cage 03, inner ring 04 and sealing ring 05. Outer ring 01 is of integral structure, two inner rings 02 are installed back to back in outer ring 01, two inner rings 02 and Steel balls 02 are evenly installed between the outer rings 01 through a cage 03 , and a sealing ring 05 is provided between...
