Description

Technical Field

[0001] The present invention relates to an oiling and assembly tooling, in particular to an automatic oiling and assembly tooling for the middle armrest guide arm. Background Art

[0002] The multi-functional front center armrest of an automobile includes a middle armrest slide seat, on which multi-functional components such as an armrest box can be arranged. The middle armrest slide seat needs to achieve its positioning function during sliding through a guide arm and a guide rod sleeved thereon. Since it is a moving part, oiling and assembly are required during the assembly process. The existing oiling process for the middle armrest uses a manual brush to dip in grease and then smear the grease on the corresponding position. The main process of manual oiling of the armrest is: apply an appropriate amount of grease on the PUR ring of the armrest slide seat, smear grease on the armrest guide rod, and smear it evenly.

[0003] The main existing problems are: the amount of grease dipped each time in the existing oiling process cannot be quantified and is only controlled by experience. After applying an appropriate amount of grease on the PUR ring of the armrest slide seat in sequence, the sleeve-type assembly of the armrest slide seat, the middle armrest guide arm, and the middle armrest guide rod needs to be completed. In the overall process, oiling and assembly are divided into two processes, which results in the inability to synchronize the rates between the two processes, leading to low overall efficiency. At the same time, the transportation, positioning, and loading and unloading of intermediate components consume a huge amount of manpower. Summary of the Invention
