Description

Technical Field

[0001] The utility model relates to the technical field, and more specifically, to a detachable square rail type boring and milling head. Background Art

[0002] In the existing machining technology, square rail type boring and milling heads are a key component widely used in high-precision machining. This type of boring and milling head is usually used for complex milling and boring operations, which has a vital impact on machining accuracy and efficiency. However, when using this type of boring and milling head, lubrication is an important link that cannot be ignored. Lubrication not only helps to reduce friction and extend tool life, but also maintains machining quality. In the existing technology, the lubrication method of square rail type boring and milling heads has certain limitations, especially in the injection method of lubricating oil.

[0003] First, the current lubrication method is mostly to inject grease from the outside of the square rail boring and milling head. Although this method is relatively simple in operation, it has problems of inefficiency and waste of resources. When injecting lubricating oil from the outside, since the lubricating oil flows outside the boring and milling head, it is difficult to ensure that the lubricating oil can evenly and effectively cover all parts that need lubrication, especially inside the boring and milling head or in hard-to-reach areas. This may lead to insufficient lubrication and affect the performance and life of the boring and milling head.

[0004] Secondly, injecting lubricating oil from the outside can easily lead to lubricating oil waste. During the lubrication process, some lubricating oil may overflow or be thrown out during the processing, and fail to be effectively used on the friction parts of the boring and milling head. This waste not only increases the operating cost, but also may pollute the working environment, especially when the lubricating oil drips on the ground or the surface of the equipment after overflowing, resulting in increased cleaning and maintenance workload.
