Abstract
The invention discloses a kind of cable core facing attachments, including dedicated tool and abutment sleeve；Dedicated tool includes that whole handle of a knife, knife bar and cutter head is made, handle of a knife is horizontally fixed in electric machine main shaft sleeve, abutment sleeve inner end screws on knife bar, cutter head is located in abutment sleeve outer end, cutter head includes several cutting edges, several cutting edge cutting edges inner end intersects on dedicated tool axis formation back taper cutting slot two-by-two, and cable core is put in across abutment sleeve outer end in back taper cutting slot when chamfering.Cable core of the present invention can disposably be correctly inserted into inner wire and split in the endoporus after slot closes up, not only greatly improve work efficiency, meet the requirement of batch production, and avoids cable core flexural deformation and the deformation of inner wire shrapnel or the generation of phenomenon of rupture in insertion process.By adjusting the relative distance on abutment sleeve between cable positioning surface and cutting edge, the chamfering angle size of final controllable cable core.
Description
Technical field
The present invention relates to a kind of cutting apparatus, especially a kind of device that chamfering can be carried out to cable core belongs to cutting
Equipment technical field.
Background technology
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 wire and coaxial cable core often use socket connection method, i.e., cable core is inserted into
In conductor endoporus, inner wire and cable core are reliably connected using the elastic force that slot closing in deformation generates of splitting of inner wire.But by
Its orifice diameter after slot closes up is split in inner wire and is less than cable core diameter, when cable core is inserted into due to the originals such as core is crooked
Cause, core end face easily touch inner wire and split slot shrapnel end face, cause core can not be successfully and inner wire is split slot shrapnel strut
It is inserted into, is inserted by force it will cause cable core flexural deformation or inner wire shrapnel 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 greatly reduce
Working efficiency.
Invention content
The object of the present invention is to provide a kind of cable core facing attachments simple in structure, at low cost, easy to operate.
The present invention 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
Handle of a knife, knife bar and cutter head, the handle of a knife 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 puts in institute across abutment sleeve outer end when chamfering
It states in back taper cutting slot.
The purpose of the present invention 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 handle of a knife 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 pass perpendicularly through abutment sleeve inner end side and withstand on knife bar
On, abutment sleeve and knife bar are connected.
The present invention has using 3-edge surgical knife carries out chamfer machining to cable core, simple in structure, at low cost, easy to operate.By
Cable core head shape splits the matching of the inner bore chamfering shape at slot closing in inner wire after chamfering so that cable core can be suitable
Profit is inserted into inner wire and is split in the endoporus after slot closes up, and can disposably be correctly inserted into place, not only greatly improves work efficiency,
Meet the requirement of batch production, and avoids cable core flexural deformation and inner wire shrapnel deformation or disconnected in insertion process
Split the generation of phenomenon.In addition, can be on left and right adjusting abutment sleeve between cable positioning surface and cutting edge by the screw thread on knife bar
Relative distance, to adjust cable core at a distance from cutting edge, the final chamfering angle size for controlling cable core.
The advantages and features of the present invention will be illustrated and explained by the non-limitative illustration of preferred embodiment below,
These embodiments only provide as an example with reference to attached drawing.
Description of the drawings
Fig. 1 is real structural schematic diagram of the invention；
Fig. 2 is the structural schematic diagram of dedicated tool of the present invention；
Fig. 3 is the structural schematic diagram of the cable core insertion inner wire after chamfering.
Specific implementation mode
The invention will be further described with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, the present invention includes dedicated tool 1 and abutment sleeve 2.Dedicated tool 1 is whole including being made
Handle of a knife 11, knife bar 12 and cutter head 13, handle of a knife 11 are horizontally fixed in electric machine main shaft sleeve 3, and are locked by the first holding screw 4
Tightly, circular orientation platform 14 is equipped between handle of a knife 11 and knife bar 12,14 inside of circular orientation platform is resisted against on electric machine main shaft sleeve 3.
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 12
On, 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 three to be uniformly distributed along the circumference
A cutting edge 131, each cutting edge cutting edge 132 are arc, and three 132 inner ends of cutting edge cutting edge intersect at dedicated tool axis two-by-two
Form back taper cutting slot 15 on line, when chamfering cable core 6 pass through 2 outer end of abutment sleeve put in back taper cutting slot 15 it is interior into
Row chamfer machining, 2 outer end of abutment sleeve are equipped with cable positioning surface 21, and cable end face is resisted against on cable positioning surface 21 when chamfering.
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
When touching, sharp cutting edge cutting edge 132 cuts away 6 surface metal of cable core, the conical chamfering of fixed angle is formed, if electric
Cable core 6 continues to move along, then the circular cone that chamfering is formed gradually increases, until eventually forming required conical chamfering.Such as
Fig. 3 show the structural schematic diagram of the insertion inner wire 7 of cable core 6 after chamfering.
In addition to the implementation, the present invention can also have other embodiment, all to use equivalent substitution or equivalent transformation shape
At technical solution, be all fallen within the protection domain of application claims.
