Chip removal box for deep-hole drilling machine

Abstract

The invention provides a chip removal box for a deep-hole drilling machine. The chip removal box comprises a first box wall, an ejector sleeve and a guide sleeve, wherein a penetrating hole, a transition cavity and a supporting hole are formed in the first box wall; a lug boss is formed on the excircle of the ejector sleeve; the ejector sleeve is inserted into the penetrating hole, the lug boss is located in the transition cavity, and the ejector sleeve can slide in the penetrating hole in the axial direction; the guide sleeve is inserted into the supporting hole, the excircle of the guide sleeve is in sealing match with the wall of the supporting hole, and the guide sleeve can slide in the supporting hole in the axial direction; and a spring is arranged between the transition cavity and the lug boss, the ejector sleeve and the guide sleeve fit with each other and are mutually sealed, and the spring can push the ejector sleeve and the guide sleeve to slide outwards. Owing to the mode that the spring ejects and pushes the sliding guide sleeve and ejector sleeve, the guide sleeve is mounted in the way of clinging to a workpiece, so that a cooling medium and the guide sleeve are prevented from being thrown away; and as the guide sleeve and the ejector sleeve are sealed with all connection parts in the sliding process, the phenomenon that resetting becomes difficult or the guide sleeve gets stuck, caused by the reason that such impurities as scrap iron are clamped into the spring, is avoided. The chip removal box is smart in structural design, obvious in getting-stuck prevention effect, simple in structure and low in manufacturing cost.

Description

technical field [0001] The invention relates to a chip removal box, in particular to a chip removal box for a deep hole drilling machine. Background technique [0002] Deep hole drilling generally refers to the drilling of hole systems with a length-to-diameter ratio greater than 10. In deep hole drilling, special customized machine tools are generally required to use specific drilling techniques. At present, advanced and efficient deep hole equipment adopts It is a drilling method with internal cooling and forced external chip removal. Most of the tools used are gun drills. The cooling medium reaches the drill head through the hollow gun drill, directly cooling and lubricating the drilling part, and removing the cut iron chips from the It is forced out of the chip flute on the gun drill to achieve the purpose of chip removal. [0003] However, the sealing performance of the existing chip removal box is very poor, and the iron filings and cooling medium are easily thrown ou...
