Specific embodiment

As shown in Figure 1, cold drill bit adapter in one kind, including ontology 1 and water jacket 2, as shown in Fig. 2, being provided in ontology 1 The gear rank 11 of annular, gear rank 11 will be divided into admission chamber 12 and out sap cavity 13, have between admission chamber 12 and out sap cavity 13 inside ontology 1 Sealing hole 14 is connected to, and is set with water jacket 2 at admission chamber 12,1 tail portion of ontology is provided with 16 axial restraint water jacket 2 of rear end cap, ontology 1 To be threadedly coupled between rear end cap 16,16 outer end face of rear end cap is equipped with Mohs cone, inner face is equipped with pushing rod 161, Water jacket 2 can opposing body 1 rotate, sealed between ontology 1 and water jacket 2 by two sealing rings 21, prevent from leaking, ontology 1 is in water Set installation site matching is provided with inlet opening 15, and the matching of water jacket 2 is provided with feed flow connector 22, and ontology 1 goes out sap cavity partial sidewall and sets It is equipped with limit screw hole 17, limit screw hole matching is provided with stop screw 18, and 1 front end of ontology is provided with drive end bearing bracket 19, drive end bearing bracket 19 include inner ring 191 and inner ring 192, wherein and outer ring is threadedly coupled with ontology, and inner ring internal diameter matches with interior cold junction outer diameter, Inner end wall between inner and outer rings is provided with sealing ring, and inner ring inner wall is also equipped with sealing ring, to guarantee after installing interior cold drill bit Sap cavity and extraneous sealing out.

Gear rank 11 at be provided with sealing-plug 3, as shown in figure 3, sealing-plug 3 by plug 31 and with the matched sealing of sealing hole 14 Bar 32, generally longitudinally section is in " ten " font to sealing-plug 3, spring 4 is provided in admission chamber 12,4 one end of spring connects rear end cap It 16 and is set in pushing rod 161, the other end connects plug 31, is clearance fit, sealing between sealing hole 14 and sealing bar 32 32 end of bar is gradually narrowed as " one " word rib, and water channel 33 is provided in sealing bar 32, and 33 entrance of water channel, outlet are all set in sealing Bar side wall.

Sealing ring is provided between 31 bottom surface of plug and gear 11 top surface of rank.

As shown in figure 4,2 outer cover of water jacket is equipped with locating part 23,23 top cambered surface of locating part matches with water-jacket outer wall, and Corresponding feed flow joint location opens limit hole 24, and for convenience of installing, limit hole 24 is set to 23 top of locating part, and locating part 23 is whole In " several " font, lower end bipod blocks machine tool track.

As shown in figure 5, ontology in use, be installed on lathe chuck, feed flow connector by adapter by Mohs cone 22 connection coolant liquid liquid feeding pipelines, interior cold drill bit end by be inserted into drive end bearing bracket inner ring 192 access out sap cavity 13, when sealing-plug not When by External force interference, gear rank 11 is close under the action of spring 4, sealing ring guarantees cold between plug lower end surface and gear rank top surface But liquid is not revealed, and after installing interior cold drill bit, sealing-plug 3 is jacked up by interior cold drill bit to plug 31 and 161 contact position of pushing rod, Since sealing boom end will not influence cooling water even if the coolant liquid mouth of interior cold drill bit is located at end face for " one " word rib Circulation, 33 entrance of water channel is connected to admission chamber 12, and sealing hole only has position-limiting action to sealing bar, allows to leak, interior cold drill bit After position determines, fixation is tightened by stop screw 18, when carrying out bore operation, coolant liquid passes through feed flow connector 22, inlet opening 15 enter admission chamber 12, then enter sap cavity 13 by sealing bar water channel, sealing hole, then enter back into interior cold drill bit, whole A procedure seals are high, to guarantee that high-pressure coolant enters interior cold drill bit in the case where being lost minimum, punching is greatly improved Hit effect.

The utility model can match difference by the drive end bearing bracket for replacing different using the same ontology The interior cold drill bit of size, inner ring internal diameter is different between the drive end bearing bracket of different model；The utility model is for interior cold drill bit coolant liquid The aperture position of mouth and direction no requirement (NR), it is applied widely.

In boring procedure, water jacket 2 does not rotate under the effect of locating part 23 with ontology, and 23 lower end bipod of locating part is seized Machine tool track makes itself to fix, and the rotation of water jacket is limited by the limit hole 24 at top, compared to common gag lever post, this Limit is more firm, and reduces security risk.

In the use of the new type, when sealing-plug in the open state, water channel entrance should be connected to admission chamber, water channel outlet answer It is connected to sap cavity out, to guarantee the circulation of coolant liquid.
