Abstract
A separate-regulatable powder-boosting type drilling chip extracting device for ejection drill is composed of oil delivering unit and drilling chip extractor. The sealed oil tanks for the said oil delivering unit and drilling chip extractor are respectively connected to the oil trank of oil pump via their branch pipes with throttle valves. Regulating of throttle valves can make the device be in optimal state to extract the drilling chip.
Description
Technical field:
The present invention relates to a kind of interior jection drill with internal discharge of drilling chip drilling chip extractor of mechanical field, relate in particular to a kind of separate-regulatable powder-boosting type drilling chip extracting device for ejection drill.
Background technology:
The deep hole machining technical development is to 20th century the mid-1970s, and Japanese metallurgical limited company releases a kind of single tube ejector drill system (Double Feeder System is called for short the DF system).This system is that the end that chip removal is bored in single tube adds a cover drilling chip extractor, and drilling chip extractor is made up of the conical nozzle body of leakproof fuel cell and a pair of convex-concave correspondence.The DF system is divided into two with cutting fluid: preceding accounts for 3/2 of cutting fluid total amount, flows into oil delivering unit, and cutting fluid flows into cutting portion by the outside of drilling rod, again through the inner chamber of drilling rod backward in chip removal; The back is propped up liquid stream and is accounted for 1/3 of total flow, after the input drilling chip extractor is taken out case, quickens through the pyramidal space acquisition of nozzle body, becomes one taper jet and sprays backward, makes negative pressure suction force of the terminal generation of drilling rod, impels the medium acceleration in the channel of chip removal to flow backward.Experiment showed, the size of effective suction force that jet produces on the chip removal direction, is the main factor of decision drilling chip extractor usefulness height.And, cause the DF system can not replace the drill gun system so far because the fixedly shunting and improper the causing of shunting ratio of DF system are taken out bits power deficiency.
Summary of the invention:
The object of the present invention is to provide a kind of separate-regulatable powder-boosting type drilling chip extracting device for ejection drill, take out the chip removal ability of bits device with raising.
For achieving the above object, technical program of the present invention lies in having adopted a kind of separate-regulatable powder-boosting type drilling chip extracting device for ejection drill, comprise oil delivering unit and drilling chip extractor, the leakproof fuel cell of oil delivering unit and drilling chip extractor links to each other with main oil stream pipeline by the branch oil stream pipeline respectively, main oil stream pipeline links to each other with oil pump, is equipped with choke valve on each branch oil stream pipeline.
Behind the choke valve Pressure gauge is being housed all on every branch oil stream pipeline.
On the described main oil stream pipeline Pressure gauge is housed.
Described drilling chip extractor by leakproof fuel cell and respectively the front nozzle and the rear nozzle that are assemblied on leakproof fuel cell antetheca and the rear wall of sealing constitute, rear nozzle is assemblied in the sealing shroud by a sealing shroud sealing that fixedly is assemblied on the leakproof fuel cell rear wall, the face of cylinder of rear nozzle leading portion is sealed and matched by the interior pipe face of sealing ring and sealing shroud, be threaded by adjusting between the back segment of rear nozzle and the sealing shroud, be equipped with a pair of locking nut on the rear nozzle body of sealing shroud rear.The inner diameter d of front nozzle

Adorned a choke valve owing to going here and there respectively on two branch oil stream pipelines that transfer to oil delivering unit and drilling chip extractor from oil pump, can realize adjusting respectively to two cutting fluid pressure, flow, make device to remain best chip removal ability according to the concrete condition timely adjustment in the operating process.The great advantage of Tiao Jieing also is to keep the flow on another road of increase and decrease under the one road constant situation respectively, and pressure loss changed instructions for use greatly when this more met deep hole machining, and practical operation is got up efficient more and is easy to grasp.The adjusting screw thread of rear nozzle is used for regulate spraying the gap, can regulate and obtain the best bits effect of taking out.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
The specific embodiment:
Among Fig. 1, originally taking out the bits device is that the master constitutes by oil delivering unit 1, drilling chip extractor 2, structural characteristics are, respectively be equipped with an economizer 6 on the oil line pipe 5 that drilling chip extractor 2 and oil delivering unit 1 link to each other with working connection pipeline 4, one Pressure gauge 7 respectively is housed behind each economizer 6, also be equipped with a Pressure gauge 7 on the main oil pipe road, whole oil circuit has oil pump feed.Drilling chip extractor 2 by leakproof fuel cell 8 and respectively the front nozzle 9 and the rear nozzle 10 that are assemblied on leakproof fuel cell 8 antethecas and the rear wall of sealing constitute, rear nozzle 10 is assemblied in the sealing shroud 12 by a sealing shroud sealing that fixedly is assemblied on leakproof fuel cell 8 rear walls, the face of cylinder of rear nozzle 10 front portions is sealed and matched by the interior pipe face of sealing ring and sealing shroud 12, be connected by regulating screw thread 11 between the middle part of rear nozzle 10 and the sealing shroud 12, be equipped with a pair of locking nut 13 on the rear nozzle body 10 of sealing shroud 12 tail ends.In the present embodiment, the inner diameter d of front nozzle
1For this drilling chip extractor can adapted 1.1 times of drilling rod internal diameter of maximum drill bit, the cone angle value of front and back nozzle is 35 °, rear nozzle throat diameter value is 1.1d
1, the length value is 0.7d
1, with throat join back one section for cone-shaped, this cone angle beta value is 50 °, final stage is a tubular, its aperture d
