Description
Technical field
The utility model relates to machine tools class, specifically a kind of deep hole machining drilling tool that facilitates chip removal.
Background technology
At present, in machining, hole depth rate aperture is greater than more than 10: 1 deep hole machining drilling tools, generally drill bit and drilling rod, consists of, and the first half of drilling rod is helicla flute part, and the rear portion of drilling rod is tail cone, and drilling tool is except drill bit and tail cone, and other part diameter is identical.Existing drilling tool is on workpiece during deep hole processing, chip removal is inconvenient, and every processing 20mm, will exit drill bit, and rinse with a large amount of water, carry out chip removal and cooling, this processing chip removal mode has affected productivity ratio, on the other hand, drill bit is extracted out outside hole and is rinsed, the water capacity is splash everywhere easily, not only affects working environment, goes back waste water resource.
Summary of the invention
The purpose of this utility model will solve existing deep hole drill chip removal inconvenience exactly, and production efficiency is low, and water resource waste is large, affects the problems such as working environment, and a kind of deep hole machining drilling tool that facilitates chip removal is provided.
Concrete scheme of the present utility model is: for existing drilling tool, improve, it has flat drill bit and drilling rod, it is characterized in that: described flat drill bit docks with a location joint screw thread, landing nipple docks with drill rod thread again, on flat drill bit, have central water flooding hole, on the front and back flat horizontal surface of flat drill bit, all have flushing hole and be communicated with central water flooding hole, on landing nipple and drilling rod, be provided with the central water flooding hole that limbers, center is communicated with flat drill bit, at the afterbody of drilling rod, be fitted with positioning sleeve and lathe hollow spindle is located by connecting, shank termination is equipped with the external water source of swivel joint; The external diameter of described landing nipple and drilling rod is less than the external diameter of chit drill, and at the landing nipple outer wall three uniform spacers that are welded, the external diameter that three spacers form equals the external diameter of flat drill bit.
The outer wall of landing nipple described in the utility model has 3-6 limit grooves, forms triangular section or quadrangle section or pentagon section or hexagonal cross-section, to facilitate chip removal and maintenance and installation.
Spacer thickness >=3mm described in the utility model on landing nipple is smooth and easy to guarantee chip removal.
The equipped positioning sleeve of the afterbody of drilling rod described in the utility model is comprised of two halves annulus, and annulus outside wall surface is provided with step surface, and the diameter of small stair face equals the internal diameter of lathe hollow spindle, to facilitate installation.
Flushing hole described in the utility model on flat drill bit becomes 20-35 ° of angle top rakes to arrange with axis.
The utility model, because anterior two flat of chit drill respectively has an apopore turning forward, flows into the water under high pressure of anterior two apopores of chit drill by pumping plant, swivel joint, drilling rod, landing nipple, chip removal ability is strong, effective; The setting of swivel joint, has guaranteed easy to connect, safe and reliable; Because chit drill head diameter is greater than drill pipe diameter, three spacers of circumferential uniform welding on landing nipple, its diameter equals chit drill head diameter, in the middle of it, is bathtub construction.It can not only guarantee boring bar head location, and borehole accuracy is high, and is conducive to iron filings and High-Pressure Water, and the slot part from landing nipple between spacer, and drilling rod and the inner chamber of having holed, oppositely go out workpiece machining hole.Realize and do not move back drill bit, can get rid of iron filings, process velocity is fast.Because depth drill is that limit work, limit are cooling, limit chip removal, so high, the cooling convenience of drilling efficiency, effective.High Pressure Drain while holing due to chit drill is to be reversed at the inner chamber of holing, and has guaranteed that chip removal is smooth and easy, and current are difficult for splash, reusable edible.Not only be conducive to working environment, also saved water resource.
