AI Technical Summary
Technical Problem
The clearance between the guide sleeve and the tool in traditional deep hole drilling leads to instability in deep hole drilling, affecting machining accuracy and lifespan, and is prone to flaring at the drill tip.
Method used
An internal chip removal deep hole drilling guide device is adopted, including an outer fixed sleeve, an inner guide sleeve, a bearing, and an end support sleeve. The bearing and angular contact bearing are used to realize the synchronous rotation of the tool and the guide sleeve, reducing wear and improving stability.
Benefits of technology
It improves the stability of deep hole drilling tools, reduces the size and length of the flared end, extends the service life of the device, and enhances machining accuracy and quality.

Abstract
本发明公开了一种内排屑深孔钻削引导装置，涉及深孔钻削的技术领域，包括外固定套、内引导套、轴承和端部支撑套，外固定套与机床固定连接，内引导套套设于外固定套内，且外固定套与内引导套之间通过轴承转动连接，端部支撑套与内引导套的端部通过轴承转动连接，端部支撑套用于与工件的加工端面抵触连接，刀具与内引导套插接的同时能够沿内引导套的轴向滑动。本发明将刀具对导向套的磨损作用转移至轴承的磨损上，利用轴承极高的使用寿命，延长内排屑深孔钻削引导装置的使用寿命；利用引导套的导向作用，使深孔钻削刀具能够稳定的钻削接触，减小深孔入口端喇叭口的尺寸与长度，缩短刀具与工件端面的预钻距离，提高深孔的加工精度。
