Description

A kind of numerical control deep-hole brill guide sleeve

Technical field

The utility model relates to a kind of numerical control deep-holes to bore guide sleeve structure.

Background technique

NC deep hole drilling machine is efficient one kind, high-precision, the high drilling machine using external chip discharging method drilling small-bore automated. It can replace the machining accuracy and surface roughness for generally requiring that the processes such as brill, expansion, hinge can be only achieved by one-time continuous drilling. After the use of the deep hole drilling machine of logarithm control after a period of time, it has been found that will appear cutting fluid suddenly in normal process from workpiece Contact leaks out at gap, workpiece bore partially, the phenomenon that even scrapping, workpiece bores polar biased and easily causes drill gun tipping or even scrap.Drill gun It turns left from the right side, respectively by oil resistant rubber shock-absorbing sleeve and guide sleeve, until the deep hole of workpieces processing.Because being limited by aperture size, The major diameter in hole is bigger, and drilling rod is thin and grows, poor rigidity, is also easy to produce vibration, and drilling easily wanders off, thus support guide is particularly important. This point is more prominent in drill gun lathe.It is crucial that drill gun is passing through guide sleeve, just when contact workpiece, because of drill thrust Greatly, to cause workpiece product mass defect.

Summary of the invention

The purpose of this utility model is to provide a kind of numerical control deep-holes to bore guide sleeve, overcomes former guide sleeve and work piece interface Product be also easy to produce less brill partially, even scrap workpieces the shortcomings that.

A kind of numerical control deep-hole bores guide sleeve, it is characterised in that: including tool locating male cone (strobilus masculinus), guide sleeve installation bolt hole, Pilot hole, guide sleeve installation outer circle, guiding inner conical surface, it is that drill gun enters guide sleeve that guiding inner conical surface, which is located at the front of guide sleeve, Top priority, play drill gun guiding and facilitate chip removal；Pilot hole is located at the center of guide sleeve, is the logical of drill gun drilling processing Road has certain guiding role and drill gun supporting role, prevents drill gun from boring inclined；Guide sleeve installation outer circle is located at the outer of guide sleeve Side, be guide sleeve be mounted on NC deep hole drilling machine bed be primarily subjected to face, play positioning and fixed function；Guide sleeve installs bolt hole It is the bolt hole that guide sleeve is mounted on NC deep hole drilling machine bed positioned at the outside of guide sleeve installation outer circle, acts the guiding that is fixedly connected The effect of set and lathe；Tool locating male cone (strobilus masculinus) is located at the tail portion of guide sleeve, and the male cone (strobilus masculinus) of preferential 60 ° of selection, is determining for workpiece Plane guarantees that workpiece and guide sleeve positioning contact area are suitable, bears the self weight of workpiece and the drill thrust of drill gun.

The utility model has the advantages that: the internal cone type guide sleeve structure generallyd use at present is improved to outer by the utility model Bevel-type has unified the positioning datum of numerical control deep-hole driller's sequence, ensure that the consistency of front and back process machining benchmark, reduces tooling Manufacture and debug time, debugging is more convenient and quick, has saved adjusting machine time, has improved tune engine efficiency, has increased the strong of tooling Degree, solves workpiece because outer rounded corner is small, and when coning angle is inconsistent in chamfer angle and guide sleeve, workpiece and guide sleeve are connect Contacting surface product is few, cannot withstand the drill thrust of drill gun, causes cutting fluid to leak out from workpiece contact gap, workpiece is bored and partially, even reported Useless quality problems.Versatility is good, and chamfering is big before can not only processing, the consistent part of chamfer angle, can also process down The part that angle is small, chamfer angle is inconsistent, increases the range of work of workpiece, to guarantee stable and reliable product quality, reduces Product gives up loss rate, meets manufacturer and the demand of client.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；Fig. 2 is utility model works schematic diagram:

In figure: tool locating male cone (strobilus masculinus) 41, guide sleeve install bolt hole 42, pilot hole 43, and guide sleeve is installed outer circle 44, led To inner conical surface 45, workpiece 1, cutting region 2, workpiece positioning surface 3, guide sleeve 4, drill gun 5, lathe headstock 6, iron filings 7.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and detailed description:

A kind of numerical control deep-hole brill guide sleeve, it is characterised in that: install bolt hole including tool locating male cone (strobilus masculinus) 41, guide sleeve 42, pilot hole 43, guide sleeve installation outer circle 44, guiding inner conical surface 45, it is rifle that guiding inner conical surface 45, which is located at the front of guide sleeve 4, 5 top priorities for entering guide sleeve 4 are bored, the guiding of drill gun 5 is played and facilitate chip removal；Pilot hole 43 is located at the center of guide sleeve 4, It is the channel of 5 drilling of drill gun processing, there is certain guiding role and drill gun supporting role, prevent drill gun 5 from boring partially；Guide sleeve peace Dress outer circle 44 is located at the outside of guide sleeve 4, be guide sleeve 4 be mounted on NC deep hole drilling machine bed be primarily subjected to face, rise positioning with Fixed function；Guide sleeve installation bolt hole 42 is located at the outside of guide sleeve installation outer circle 44, is that guide sleeve 4 is mounted on numerical control deep-hole The bolt hole of drilling machine tool acts be fixedly connected guide sleeve and lathe；Tool locating male cone (strobilus masculinus) 41 is located at the tail of guide sleeve 4 Portion, the male cone (strobilus masculinus) of preferential 60 ° of selection, is the positioning surface of workpiece 1, guarantees that workpiece 1 and the positioning of guide sleeve 4 contact area are suitable, holds By the self weight of workpiece 1 and the drill thrust of drill gun 5.

Bolt hole 42 is installed by adjusting guide sleeve and guide sleeve installs outer circle 44, the utility model is mounted on numerical control depth On hole drill lathe, workpiece 1 is after the installation positioning of tool locating male cone (strobilus masculinus) 41, the main shaft drives drill gun 5 of lathe headstock 6, drill gun Enter pilot hole 43 by guiding inner conical surface 45, is in close contact by guide sleeve 4 and workpiece positioning surface 3, and in tool locating Male cone (strobilus masculinus) 41 and 43 intersection of drill gun pilot hole start drilling processing, and cutting fluid enters cutting with high pressure, from the fuel feed hole of drill gun 5 Area 2 forces iron filings 7 to be discharged with cutting fluid by the hole wall space of V slot and workpiece 1 and guiding inner conical surface 45, and final drilling is completely a Stroke.Ensure the concentricity requirement of drill rod rack, cutter guide sleeve and headstock spindle and drill rod box main shaft.Because this is practical Novel guide sleeve structure is outer bevel-type, and identical as workpiece centre orifice angle, contact area is more, thus because not before solving With excircle of workpiece chamfering, small, chamfer angle and coning angle in former guide sleeve are inconsistent, cause cutting fluid from workpiece contact gap Quality problems that are inclined, even scrapping are bored in leakage, workpiece, finally ensure the stability of workpiece product quality.

It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field For personnel, make several equivalent substitute or obvious modifications without departing from the concept of the premise utility, and performance or Purposes is identical, then shall be regarded as belonging to the protection scope that claims that the utility model is submitted determine.
