Description

Technical Field

[0001] The present application relates to the technical field of boring equipment, and in particular to an oil lubrication mechanism of boring equipment. Background Art

[0002] In the modern machinery manufacturing industry, boring equipment, as a high-precision and high-efficiency hole processing equipment, is widely used in many fields such as automotive parts, aerospace, energy equipment, etc. However, during the long-term high-speed operation of boring equipment, the friction loss between the spindle and the tool holder is large, and continuous and uniform lubrication is required to reduce wear, reduce heat generation, and ensure processing accuracy and equipment life.

[0003] In traditional methods, many devices rely on manual lubrication and maintenance on a regular basis. This method has many shortcomings: First, manual lubrication cannot provide the necessary lubricant to the spindle in real time and quantitatively, which can easily lead to uneven or excessive lubrication, and then cause problems such as poor lubrication or waste of lubricant; in addition, the frequency and timing of manual lubrication are difficult to accurately grasp, especially in a continuous operating environment. The long lubrication interval may cause dry friction between the spindle and the bearing, aggravating wear and shortening the life of the equipment.

[0004] Another common lubrication strategy is to pre-fill a large amount of lubricating oil in the rotating slot of the spindle, hoping to achieve the lubrication purpose through the oil pool effect. However, this method also has its obvious disadvantages: on the one hand, excessive lubricating oil may cause leakage to pollute the working environment and increase safety risks; on the other hand, spindle components immersed in lubricating oil for a long time may accelerate the aging of seals and cause leakage.
