Abstract
The utility model relates to a deep hole ejector drill used for deep-hole processing. The deep hole ejector drill fixes a blade and a conducting bar through clamping screws, uses the pressure of cutting fluid to press cutting scraps into a hollow drill body through an inner scrap-discharging groove to discharge the cutting scraps, and therefore scrap-discharging effect and cooling effect are achieved. A cutting edge or the blade can be directly replaced conveniently and fast when the blade is worn or broken, and overall scraping is not caused. The deep hole ejector drill saves cost and improves efficiency.
Description
Technical field
The utility model relates to the Deep-Hole Drilling Technology field, relates in particular to a kind of deep-hole spray and inhales brill.
Background technology
In machining, Drilling operation accounts for 1/3rd of its processing total amount, progress along with science and technology, in the engineering goods parts machining, the accuracy of position, hole and the fineness on surface are required day by day to improve, and the processing of PRECISION HOLE usually becomes the key of production, and especially in deep hole machining, knife bar is subjected to the restriction in aperture, diameter is little, length is large, relatively cause poor rigidity, intensity is low, has a strong impact on product quality, in addition chip removal difficulty in the deep hole machining, the cutting fluid cast does not catch up with, temperature raises, and causes tool life to weaken, and import cutter price is very expensive again, what circulated in the market now is integral body or welded type depth drill mostly, can only integral body scrap after sword is blunt, virtually increased cost, wasted resource, thereby just need a kind of chip removal badly, the cooling ability is strong, and the deep-hole spray of energy Reusability is inhaled brill.
Summary of the invention
In order to overcome the above problems, the utility model provides a kind of deep-hole spray to inhale and bores, and minute bits, chip removal, cooling ability are strong, can pass through replacing blade, cutter holder Reusability.
The technical solution of the utility model is: provide a kind of deep-hole spray to inhale and bore, it comprises pinching screw, center insert, intermediate blades, the cylindrical blade, sliver, the center cutter holder, the hollow drill body, middle cutter holder, the cylindrical cutter holder, adjust screw and interior chip area, it is characterized in that center insert is fixed on the center cutter holder of two locating surfaces by pinching screw, the center cutter holder is fixed on the hollow drill body by adjusting screw, intermediate blades is fixed on the middle cutter holder by pinching screw, middle cutter holder is fixed on the hollow drill body by adjusting screw, the cylindrical blade is fixed on the cylindrical cutter underedge of two locating surfaces by pinching screw, the cylindrical cutter holder is fixed on the hollow drill body by adjusting screw, sliver is fixed on the side of hollow drill body by pinching screw, and the inner spout of hollow drill body is provided with interior chip area.
Compared with prior art, the invention has the beneficial effects as follows: the energy replacing blade, Reusability, blade have three cutting edges, utilization rate is high, and blade passed through the locating surface pretightning force and clamps, and cutter holder is adjustable, the unlikely cutter hub that injures after damaging, and minute bits, chip removal ability are strong, and the cooling ability is strong.
Description of drawings
The below further is illustrated the utility model with reference to the accompanying drawings
Accompanying drawing 1 is structure chart of the present utility model;
Accompanying drawing 2 is side views of the present utility model;
Shown in the figure: 1, pinching screw, 2, center insert, 3, intermediate blades, 4, the cylindrical blade, 5, sliver, 6, the center cutter holder, 7, the hollow drill body, 8, middle cutter holder, 9, the cylindrical cutter holder, 10, adjust screw, 11, interior chip area.
The specific embodiment
Such as Fig. 1, shown in Figure 2, deep-hole spray is inhaled and is bored, it comprises pinching screw 1, center insert 2, intermediate blades 3, cylindrical blade 4, sliver 5, center cutter holder 6, hollow drill body 7, middle cutter holder 8, cylindrical cutter holder 9, adjust screw 10 and interior chip area 11, it is characterized in that center insert 2 is fixed on the center cutter holder 6 of two locating surfaces by pinching screw 1, center cutter holder 6 is fixed on the hollow drill body 7 by adjusting screw 10, intermediate blades 3 is fixed on the middle cutter holder 8 by pinching screw 1, middle cutter holder 8 is fixed on the hollow drill body 7 by adjusting screw 10, cylindrical blade 4 is fixed on 9 li of the cylindrical cutter holders of two locating surfaces by pinching screw 1, cylindrical cutter holder 9 is fixed on the hollow drill body 7 by adjusting screw 10, sliver 5 is fixed on the side of hollow drill body 7 by pinching screw 1, and the inner spout of hollow drill body 7 is provided with interior chip area 11.
In use; deep-hole spray is inhaled the cutting fluid of boring certain pressure and is pressed into outside cutter hub in the machining district; cutter hub is cooled off; for the high speed deep hole machining provides safeguard; utilize simultaneously the internal pressure of cutter hub; iron filings sucking-off from hollow drill body 7; do not injure the surface smoothness of machining hole, improved crudy, in order to lengthen and to extend drill body; the hickey of hollow drill body 7 afterbodys and the screw thread mouth of lathe or extension rod are joined work; each blade has three cutting edges, and blade wearing and tearing occur or collapses when broken, directly the cutting edge of allowing blade replacement or more allowing blade replacement is all very convenient more; fast; cutter holder is not damaged for the protection of cutter hub, and economic serviceability is heightened greatly.
The above is embodiment of the present utility model, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All any modifications of within spirit of the present utility model and principle, doing, be equal to replacement, improvement etc. and all should be contained within the claim scope of the present utility model.
