Description
Technical field
The utility model relates to a kind of fastening piece, and more particularly, it relates to cooling and lubricating tapping screw.
Background technique
Tapping screw in the pre-drilled of metal or nonmetallic material, attacks the one getting out female thread joined together voluntarily have threaded fasteners.Tapping screw is used for the connection between thin sheet metal (steel plate, saw plate etc.).During connection, first thread Pilot hole is made to connected piece, then tapping screw is screwed in the thread Pilot hole of connected piece.Thread surface due to tapping screw has higher hardness (>=45HRC), can in the thread Pilot hole of connected piece tapping internal thread, thus formed connect.
General tapping screw is all coordinate electric screw driver to use together, because electric screw driver rotating speed is very fast, when attacking hole, rubbing contact area is also very large, so be very easy in use make screw generate heat, cause by screw thread joint place because fever expansion causes deformation, screw-thread fit place excesssive gap is easily caused after recovering shape after the cooling period, affect fastening effect, and after screw shot by screw, especially easily wear and tear at the flank of thread of screw like this, and the more important thing is, screw will be caused so stuck in fastened thing, be difficult to take out.
In existing market, application number is the screw disclosing a kind of convenient lubrication of 201420436959.5, comprise head and from head to the screw rod of downward-extension, the end face of described screw rod opposing headers is provided with circular groove, the slide block of slip is provided with in described circular groove, one end of one end screw rod relative to head of described slide block is fixedly connected with, shoe cream room is provided with in described slide block, although it can when attacking hole to the effect of cooling, but there is following defect: first, even if when not producing larger heat, when attacking hole, screw rod is extruded fuel-displaced cooling, easily cause the waste of fluid, secondly, lubricant oil in liquid storage cylinder flows out under gravity automatically, can not well be distributed on screw thread, cause lubrication effect not good.
Model utility content
Cause the deficiency of easy corrosion for can not the extruding formation oil film after attacking hole of prior art existence, the purpose of this utility model is to provide a kind of thread surface formation oil film that can be formed in after attacking hole prevent corrosion and prevented the screw of screw thread surface expanded by heating by oil film.
For achieving the above object, the utility model provides following technological scheme: a kind of cooling and lubricating tapping screw, comprise spiral shell head and screw rod, described screw rod is provided with oil pocket, described oil pocket is communicated with oil road and oil input channel, the side surface of described screw rod be provided be communicated with oil road go out oil groove, describedly go out also to be provided with oil absorbent material in oil groove, described oil absorbent material is also arranged with expansion of metal ring, described oil absorbent material is fixed on out in oil groove by expansion of metal ring, described oil input channel has been threaded force feed pin, described force feed pin one end is provided with the force feed spiral shell head for coordinating screw-driver, the other end is provided with force feed rubber sleeve, the inwall interference fit of described force feed rubber sleeve and oil input channel.
Under normal circumstances, although oil pocket is communicated with by oil road with oil outlet, but because oil outlet position is provided with oil absorbent material, when expansion of metal ring does not have expanded by heating, it locks oil absorbent material, the exposed part going out oil groove positions of oil absorbent material is tightened up, its internal voids is caused to reduce, fluid cannot ooze out into screw surface from space, when user uses electric screw driver to carry out attacking hole, produce larger heat, due to surface and the screw rod thermal contact conductance of expansion of metal ring, expansion of metal ring expanded by heating, the space of oil absorbent material inside is made to become large, fluid can be oozed out from oil outlet, play and prevent overheated effect, and attacking after hole completes, inner fluid cannot be utilized by continuation, can again by force feed pin be inserted into oil duct, due to oil pressure less (because the gap between screw thread and fastened thing is more) at the beginning, so insertion is comparatively easy, fluid will be squeezed out the outside of oil outlet via oil road, then along with force feed pin constantly downwards, oil pressure increases gradually, be difficult to continuation and will enter lubrication by hydraulic pressure, at this moment the force feed by being arranged at force feed pin is threaded into the internal thread of oil input channel, fluid is continued to extrude from oil outlet, make fluid can cover slow whole surface of contact as much as possible, play the effect of lubrication, when summer, fastened thing expanded, force feed pin can also be unscrewed, inner relative pressure is reduced, make the utility model be not easy stuck causing can not take out.
The utility model can be set to further: described in go out the pitch place that oil groove is arranged at described screw rod.
By going out the position being arranged on path of oil groove, when can ensure fuel-displaced, lubricant oil can along with under the surface in large footpath slowly oozes, and can not affect large footpath attack hole time efficiency.By being equipped with of the first sphenoid surface and the second sphenoid surface, just can when screwing in force feed pin, play a spacing effect, and the second sphenoid surface also plays the function that facilitates oiling.
The utility model can be set to further: described spiral shell head is provided with interior hexagonal screw channel, the bottom of described interior hexagonal screw channel is provided with the oil inlet hole be communicated with oil input channel, described force feed spiral shell head is provided with the first sphenoid surface, and described oil inlet hole is provided with the second sphenoid surface coordinated with the first sphenoid surface.
By being equipped with of the first sphenoid surface and the second sphenoid surface, just can when screwing in force feed pin, play a spacing effect, and the second sphenoid surface also plays the function that facilitates oiling.
Compared with prior art, the utility model has the advantage of: one can play an effect cooled when attacking hole, two carry out force feed pin can lubricate remaining fluid utilization screw of the present utility model.
