The function accessories such as milling head, the processing in five faces can be completed by being once loaded, and can greatly improve production efficiency, therefore every machine
Bed it is more or less be equipped with several accessories mill-heads to meet the requirements of various processing parts.But be loaded every time accessories mill-head when
It is required for manually observing whether machine tool chief axis normally docks with annex main shaft, and appropriate adjustment need to be carried out to annex main shaft, often
Secondary be loaded all takes time and effort.
The content of the invention
The purpose of the present invention is to be directed to problems of the prior art and deficiency, there is provided a kind of accessories mill-head main shaft orientation
Structure, to ensure that machine tool chief axis normally docks with annex main shaft, operating efficiency when being loaded accessories mill-head is improved, changed to be automatic
Annex provides basis.
The technical solution adopted for the present invention to solve the technical problems is：A kind of accessories mill-head spindle positioning structure is provided,
Including accessories mill-head main shaft, transitional shell, positioning driver plate, compression spring, positioning key block, transverse minor axis, alignment pin.Described is attached
Part milling head spindle positioning structure is：Accessories mill-head main shaft is arranged in transitional shell, and positioning driver plate is fixed on accessories mill-head main shaft
End, accessories mill-head main shaft can be driven to be freely rotatable；Logical keyway is provided with positioning driver plate, positioning key block is arranged on
In transitional shell；Waist-shaped hole and the column type hole intersected parallel with waist-shaped hole are provided with positioning key block, in described column type hole
Compression spring is provided with, transverse minor axis is placed in column type hole and contacted with compression spring, and alignment pin passes through the waist in positioning key block
Type hole is placed in transverse minor axis.
Logical keyway on described positioning driver plate, its width dimensions should be bigger than the appearance and size of alignment pin, general to require not
More than 0.5~4mm, ensure that alignment pin can be freely by positioning the logical keyway on driver plate.
Column type bore dia size above described positioning key block is more than the appearance and size of compression spring, in the column type hole
Heart line is parallel with the mounting hole in positioning key block and has with mounting hole and intersects, and column type hole and the cylindrical of transverse minor axis are matched somebody with somebody for transition
Close；The original position of waist-shaped hole should be no more than positioning driver plate after mounting, and the length of mounting hole should be greater than positioning the logical keyway of driver plate
Thickness and alignment pin thickness sum.
Described compression spring is round steel wire cylindrical pressure spring, and its decrement should meet the design level movement of alignment pin
The requirement of distance.
Described transverse minor axis, in an initial condition, reply round steel wire cylindrical pressure spring apply certain pressure, at first
Contacted with machine tool chief axis.
It described alignment pin, after assembling, should insert in the logical keyway of positioning driver plate, prevent from positioning the rotation of driver plate,
When machine tool chief axis is close, transverse minor axis is touched, when axially promoting transverse minor axis, alignment pin moves together with transverse minor axis, most
Positioning driver plate is exited eventually, does not influence to position the rotation of driver plate, round steel wire cylindrical pressure spring is compressed with certain elastic force；Work as machine
When bed main shaft retreats, transverse minor axis moves outward in the case where the elastic force of round steel wire cylindrical pressure spring promotes, and drives alignment pin to enter
Position driver plate to lead in keyway, prevent from positioning the rotation of driver plate, so as to fix annex main shaft.
Accessories mill-head spindle positioning structure described in the present invention, can ideally solve existing skill with simpler and more direct structure
Technical problem present in art.With rational in infrastructure, manufacturing cost is cheap, and operation operation is simple, and without manually observing, adjusting
It is to ensure that machine tool chief axis normally docks with annex main shaft, realizes with low cost, simple and direct mode, good effect,
Operating efficiency when being loaded accessories mill-head is improved, is further provided for automatic replacing annex automation and digital control system good
Good basis.
Brief description of the drawings
Accompanying drawing 1：Accompanying drawing 1 is the structural representation front view of the present invention；
Accompanying drawing 2：The A direction views after main shaft are removed for accompanying drawing 1.
Embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that the embodiment be merely to illustrate the present invention and
It is not used in limitation the scope of the present invention.In addition, it is to be understood that after the content that the present invention is told about has been read, those skilled in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
As shown in Figure 1, this annex spindle positioning structure, including transitional shell 1, transitional shell 1 is horizontal positioned, in transition
Annex main shaft 2, positioning driver plate 3, positioning key block 4 are provided with housing 1；Positioning driver plate 3 is connected with annex main shaft 2, can be driven attached
Part main shaft 2 rotates；Logical keyway 9 is installed with positioning driver plate 3, positions in the column type hole of key block 4 and is provided with round steel wire cylindricality pressure
Power spring 5 and transverse minor axis 6, are provided with the mounting hole of alignment pin 7 in transverse minor axis 6, and alignment pin 7 is passed through in positioning key block 4
Waist-shaped hole 10 is fixed in transverse minor axis 6 by the mounting hole in transverse minor axis 6.It should ensure that waist of the alignment pin 7 in positioning key block 4
The original position of type hole 10, the insertion of alignment pin 7 are positioned in the logical keyway 9 of driver plate 3, the rotation of limitation positioning driver plate 3, i.e. annex
Main shaft is positioned.Transverse minor axis 6 can apply certain pressure to round steel wire cylindrical pressure spring 5, and transverse minor axis 6 should be than positioning
