Technical Field

[0001] The utility model relates to an automatic telescopic crankshaft upper bearing bush fixed-point oiling device, belonging to the technical field of engine assembly and adjustment. Background Art

[0002] In the process of automobile engine manufacturing, the assembly of crankshaft bearings is a crucial link, and its assembly quality is directly related to the performance and life of the engine. In the process of crankshaft bearing assembly, lubrication of the upper bearing is an indispensable step. At present, manual lubrication is widely used in the industry for this operation.

[0003] Although the manual oiling method is simple and easy, it has many shortcomings during use. First, when manually applying oil with a manual oiler, the amount of oil applied is often difficult to accurately control. Uneven oiling will lead to poor lubrication of the bearing, thereby increasing the risk of bearing strain and posing a potential threat to the quality of the engine. Secondly, if the manual oiling is excessive, it will not only cause a waste of resources, but also increase the assembly cost of a single engine, which is not conducive to the economic benefits of the enterprise.

[0004] In addition, manual oiling is inefficient and cumbersome. It takes a long time for an operator to master this operation skill, usually requiring at least two months of training. This not only increases the company's training costs, but also affects the overall efficiency of the production line. Utility Model Content
