Description
Technical field
The utility model relates to a kind of cutting apparatus, especially a kind of device that chamfering can be carried out to cable core belongs to
Cutting apparatus technical field.
Background technique
Radio frequency connector in radio frequency co-axial cable subassembly is generally divided into welded type with the connection type of coaxial cable, crimps
Formula and plug-in type, wherein connection type the most reliable is welded type, but since many products need execute-in-place, without condition
Welded, connector inner conductor and coaxial cable core often use socket connection method, i.e., cable core is inserted into
In conductor inner hole, inner conductor and cable core are reliably connected using the elastic force that slot closing in deformation generates of splitting of inner conductor.But by
Its orifice diameter after slot closes up is split in inner conductor and is less than cable core diameter, when cable core insertion due to originals such as core skews
Cause, core end face easily touch inner conductor and split slot elastic slice end face, cause core can not be successfully and inner conductor is split slot elastic slice strut
Insertion is inserted by force it will cause cable core bending deformation or inner conductor elastic slice part deformation even fracture, is especially criticized
When amount production, cable core often can not be disposably correctly inserted into place, and need to be repeated several times can just be inserted in place, and be greatly reduced
Working efficiency.
Utility model content
A kind of the purpose of the utility model is to provide structures simple, at low cost, easy to operate cable core facing attachment.
The utility model is achieved by the following technical programs:
A kind of cable core facing attachment, including dedicated tool and abutment sleeve；The dedicated tool includes that entirety is made
Knife handle, knife bar and cutter head, the knife handle is horizontally fixed in electric machine main shaft sleeve, and abutment sleeve inner end screws on knife bar,
Cutter head is located in abutment sleeve outer end, and the cutter head includes the several cutting edges being uniformly distributed along the circumference, several cutting edge cutting edges inner end
Intersect on dedicated tool axis formation back taper cutting slot two-by-two, cable core passes through abutment sleeve outer end and puts in institute when chamfering
It states in back taper cutting slot.
The purpose of this utility model can also be further realized by following technical measures.
Cable core facing attachment above-mentioned, wherein the cutting edge cutting edge is arc.
Cable core facing attachment above-mentioned, wherein being equipped with circular orientation platform between the knife handle and knife bar, annular is fixed
It is resisted against on electric machine main shaft sleeve on the inside of the platform of position.
Cable core facing attachment above-mentioned, wherein the abutment sleeve outer end is equipped with cable positioning surface, electricity when chamfering
Cable-end face is resisted against on the cable positioning surface.
Cable core facing attachment above-mentioned, wherein holding screw passes perpendicularly through abutment sleeve inner end side and withstands on knife bar
On, abutment sleeve and knife bar are connected.
The utility model has using 3-edge surgical knife carries out chamfer machining to cable core, and structure is simple, at low cost, operation side
Just.It splits the inner bore chamfering shape at slot closing in due to cable core head shape after chamfering and inner conductor to match, so that cable
Core can smoothly be inserted into inner conductor and split in the inner hole after slot closes up, and can disposably be correctly inserted into place, not only substantially increase work
Make efficiency, meet the requirement of batch production, and avoids cable core bending deformation and inner conductor elastic slice in insertion process
Deformation or the generation of phenomenon of rupture.In addition, by the screw thread on knife bar can on left and right adjusting abutment sleeve cable positioning surface with cut
The relative distance between sword is cut, so that cable core is adjusted at a distance from cutting edge, the final chamfering angle size for controlling cable core.
The advantages of the utility model and feature will carry out diagram reconciliation by the non-limitative illustration of preferred embodiment below
It releases, these embodiments, is only provided as an example referring to attached drawing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model reality；
Fig. 2 is the structural schematic diagram of the utility model dedicated tool；
Fig. 3 is the structural schematic diagram of the cable core insertion inner conductor after chamfering.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, the utility model includes dedicated tool 1 and abutment sleeve 2.Dedicated tool 1 is whole including being made
Knife handle 11, knife bar 12 and the cutter head 13 of body, knife handle 11 are horizontally fixed in electric machine main shaft sleeve 3, and pass through the first holding screw 4
Locking is equipped with circular orientation platform 14, is resisted against electric machine main shaft sleeve 3 on the inside of circular orientation platform 14 between knife handle 11 and knife bar 12
On.2 inner end of abutment sleeve screws on knife bar 12, and the second holding screw 5 passes perpendicularly through 2 inner end side of abutment sleeve and withstands on knife bar
On 12, abutment sleeve 2 and knife bar 12 are locked, cutter head 13 is located in 2 outer end of abutment sleeve, and cutter head 13 includes being uniformly distributed along the circumference
Three cutting edges 131, each cutting edge cutting edge 132 are arc, and three 132 inner ends of cutting edge cutting edge intersect at dedicated tool two-by-two
Back taper cutting slot 15 is formed on axis, cable core 6 passes through 2 outer end of abutment sleeve and puts in back taper cutting slot 15 when chamfering
Chamfer machining is carried out, 2 outer end of abutment sleeve is equipped with cable positioning surface 21, and cable end face is resisted against cable positioning surface 21 when chamfering
On.
When 6 chamfering of cable core, cable core 6 is moved along 1 axis of dedicated tool to three 131 directions of cutting edge,
The high speed rotation under motor drive of dedicated tool 1 simultaneously, forms cutting force, when cable core 6 and three cutting edge cutting edges 132 connect
