Technical Field
[0001] The utility model relates to the field of automobile fan assembly, and more specifically, to a tightening machine for the rear cover of an automobile fan assembly. Background Art
[0002] An automobile fan is a fan that plays a heat dissipation function in an automobile and can dissipate heat inside the automobile. During the process of manufacturing and assembling the automobile fan, when installing the rear cover of the fan onto the semi-finished motor of the fan, screws are required to assemble and lock the rear cover and the semi-finished motor. In order to improve the efficiency of fan assembly, factories often use automatic screw locking machines.
[0003] When the existing automatic screw locking machine transfers the rear cover of the fan onto the semi-finished motor, it is unable to position the rear cover, resulting in misalignment of the screw holes for locking between the rear cover and the semi-finished motor. Workers need to first align the corresponding screw holes between the rear cover and the semi-finished motor, and then the automatic screw locking machine uses screws to assemble and lock the rear cover onto the semi-finished motor. After long hours of work, the efficiency of workers will gradually decrease, and their attention will also be prone to distraction, resulting in misalignment of the corresponding screw holes between the rear cover and the semi-finished motor, leading to abnormalities in the assembly of the fan rear cover.
