Description
Technical field
This utility model relates to a kind of machine tool accessory, particularly relates to the revolution swivel nut of a kind of micrometer adjustement boring tool unit.
Background technology
Fine setting cutting unit is the core component of accurate boring class cutter, and in existing universal technology, micrometer adjustement boring tool cuts
Unit includes that outer sleeve, knife bar, and the revolution swivel nut being arranged in outer sleeve, revolution swivel nut two ends are both supported upon on spring；
One end of knife bar is by being threadably mounted in the internal thread hole of revolution swivel nut.By along counterclockwise rotating revolution swivel nut, band
Moving knife bar does the reciprocating motion of axis direction along outer sleeve.
The female thread wherein turning round swivel nut is whole screw thread, by cutting out axile displacement and reverse narrow at revolution swivel nut
Groove, makes narrow slot generation plastic deformation by external force so that female thread occurs pitch deformation in this place before assembling in advance.Screwing in cutter
After bar, thread pitch can be partially removed.But in practice, allow narrow slot deform by external force so that pitch reaches one rationally
Deflection is extremely difficult；Deform the least, do not reach and Screw Thread Fit Clearance is completely eliminated；Deform excessive, then make two sections of screw threads of before and after
Cannot link up and cause product cannot assemble at all.And this deformation must complete when assembling, it is difficult to the palm
Holding deflection, during the use after having assembled, the most likely narrow slot deformation-recovery causes screw thread to get rid of gap inefficacy, also
May counteract originally by the effect of narrow slot eliminating deformation thread pitch due to the abrasion of screw thread after not using for a long time, produce
New screw thread working clearance, screw thread transmission is made to lose transmitting accuracy.And, the narrow slot of existing structure is opened in revolution swivel nut
At screw thread, screw thread and the deformed threads of narrow slot intersection, have a strong impact on the quality of fit of revolution swivel nut and knife bar.
Utility model content
This utility model aims to provide the revolution swivel nut of micrometer adjustement boring tool unit, uses micrometer adjustement boring tool unit of the present utility model
The thread pitch of knife bar screw thread and revolution swivel nut can be got rid of easily and reliably, it is achieved knife bar is relative with the gapless of revolution swivel nut to be transported
Dynamic.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is as follows:
The revolution swivel nut of a kind of micrometer adjustement boring tool unit, described revolution swivel nut outer circumference surface has annular boss, described annular
Radially having narrow slot on the external cylindrical surface of boss, the degree of depth of narrow slot is more than the radius of external cylindrical surface at this；Set in revolution swivel nut
Put undercut and the internal thread hole of revolution swivel nut is separated into two sections；Described narrow slot is positioned at undercut, and described narrow slot has two, and two
Individual narrow slot axially offsets, and two narrow slot opening directions differ 180 degree.
Further, the degree of depth of described narrow slot is equal to the radius sum of the radius of external cylindrical surface at this with undercut.
Further, described revolution swivel nut one end axially has hexagonal and pulls mouth.
Further, described internal thread hole is blind hole.
Further, the outer circumference surface that described revolution swivel nut hexagonal is pulled at mouth has screw thread.
Further, described annular boss is integrally manufactured with revolution swivel nut.
Compared with prior art, this utility model has the advantages that
This utility model arranges undercut and the internal thread hole in revolution swivel nut is divided into two sections, simultaneously empty at revolution swivel nut
The reverse narrow slot of axile displacement at two is cut out at cutter groove.Use micrometer adjustement boring tool unit of the present utility model at the pressure of spring
Under effect, the deformation of the narrow slot generation trace that two places are opened and make two sections of the most coherent screw thread generation axial deformations, get rid of cutter
Bar screw thread and the thread pitch turning round swivel nut, it is achieved that knife bar and the gapless relative motion turning round swivel nut.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, to this reality
It is further elaborated with novel.
Embodiment 1
As it is shown in figure 1, the revolution swivel nut of micrometer adjustement boring tool unit disclosed in the present embodiment, revolution swivel nut outer circumference surface there is ring
Shape boss 1, the external cylindrical surface of annular boss 1 radially has narrow slot 2, and the degree of depth of narrow slot 2 is more than the radius of external cylindrical surface at this；
Undercut 3 is set in revolution swivel nut the internal thread hole of revolution swivel nut is separated into two sections；Narrow slot 2 is positioned at undercut 3, narrow slot
2 have two, and two narrow slot 2 axially offset, and two narrow slot 2 opening directions differ 180 degree.The internal thread hole of revolution swivel nut is blind
Hole, revolution swivel nut one end axially has hexagonal and pulls mouth 4, and the outer circumference surface that revolution swivel nut hexagonal is pulled at mouth 4 has screw thread.Convex annular
Platform 1 is integrally manufactured with revolution swivel nut.
Embodiment 2
The present embodiment is with the difference of embodiment 1: the degree of depth of narrow slot 2 is equal to radius and the undercut of external cylindrical surface at this
The radius sum of 3.
As it is shown on figure 3, this utility model is coaxially mounted in outer sleeve 5, one end of knife bar 6 is by being threadably mounted at this reality
With in novel internal thread hole, spring 7, spacing plain washer 8 and locking nut 9 are all enclosed within this utility model, locking nut 9 with
