Art
The present invention relates to the accessories mill-head spindle positioning structure of a kind of big machinery process equipment, particularly to the accessories mill-head spindle positioning structure of large-size horizontal digital-control boring-milling machine.
Background technology
Along with processing, manufacturing develop rapidly, domestic each relevant manufacturer is also more and more higher to the requirement of machining tool, floor type boring and milling machine is except having the functions such as very strong milling, bore hole, boring, the function accessories such as high precision numerical control rotary table, milling head in collocation, once it is installed and can complete the processing in five faces, can greatly improve production efficiency, therefore every lathe more or less be equipped with several accessories mill-head to meet the requirement of various processing part.But be installed every time accessories mill-head time be required for whether manual observation machine tool chief axis normally docks with adnexa main shaft, and adnexa main shaft need to be carried out suitable adjustment, be installed every time and all take time and effort.
Summary of the invention
It is an object of the invention to for problems of the prior art and deficiency, it is provided that a kind of accessories mill-head spindle positioning structure, to ensure that machine tool chief axis normally docks with adnexa main shaft, improve work efficiency when being installed accessories mill-head, provide basis for automatically changing adnexa.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of accessories mill-head spindle positioning structure, including accessories mill-head main shaft, transitional shell, location driver plate, compression spring, positioning key block, transverse minor axis, alignment pin.Described accessories mill-head spindle positioning structure is: accessories mill-head main shaft is arranged in transitional shell, and location driver plate is fixed on the end of accessories mill-head main shaft, it is possible to drive accessories mill-head main shaft to be freely rotatable；Being provided with logical keyway on the driver plate of location, positioning key block is arranged in transitional shell；Positioning key block is provided with waist-shaped hole and the column type hole intersected parallel with waist-shaped hole, it is provided with compression spring in described column type hole, transverse minor axis is placed in column type hole and contacts with compression spring, and alignment pin is placed in transverse minor axis through the waist-shaped hole on positioning key block.
The described logical keyway on the driver plate of location, its width dimensions should be bigger than the overall dimensions of alignment pin, and general requirement is not more than 0.5～4mm, it is ensured that alignment pin can freely by positioning the logical keyway on driver plate.
The described column type bore dia above positioning key block is sized larger than the overall dimensions of compression spring, and the centrage in this column type hole is parallel with the mounting hole on positioning key block and has with mounting hole and intersects, and the cylindrical of column type hole and transverse minor axis is interference fits；The original position of waist-shaped hole after mounting should less than location driver plate, and the length of mounting hole should be greater than thickness and the alignment pin thickness sum of the logical keyway of location driver plate.
Described compression spring is round steel wire cylindrical pressure spring, and its decrement should meet the requirement of the design level displacement of alignment pin.
Described transverse minor axis, in an initial condition, reply round steel wire cylindrical pressure spring applies certain pressure, contacts with machine tool chief axis at first.
Described alignment pin, after assembling, should insert in the logical keyway of location driver plate, it is prevented that the rotation of location driver plate, when machine tool chief axis is close, touch transverse minor axis, when axially promoting transverse minor axis, alignment pin moves together with transverse minor axis, finally exits location driver plate, not affecting the rotation of location driver plate, round steel wire cylindrical pressure spring is compressed with certain elastic force；When machine tool chief axis retreats, transverse minor axis moves outward under the elastic force of round steel wire cylindrical pressure spring promotes, and drives alignment pin to enter in the logical keyway of location driver plate, it is prevented that the rotation of location driver plate, thus fixing adnexa main shaft.
Accessories mill-head spindle positioning structure described in the present invention, it is possible to ideally solve the technical problem existed in prior art with simpler and more direct structure.Have rational in infrastructure, cheap for manufacturing cost, operation runs simple, and it is to ensure that machine tool chief axis normally docks with adnexa main shaft without manual observation, adjustment, achieve with low cost, simple and direct mode, good effect, improve work efficiency when being installed accessories mill-head, further provide good basis for replacing adnexa automatization and digital control system automatically.
Accompanying drawing explanation
Accompanying drawing 1: accompanying drawing 1 is the structural representation front view of the present invention；
Accompanying drawing 2: remove the A direction view after main shaft for accompanying drawing 1.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is expanded on further.Should be understood that this embodiment is merely to illustrate the present invention rather than restriction the scope of the present invention.In addition, it is to be understood that after having read the content that the present invention tells about, the present invention can be made various changes or modifications by those skilled in the art, these equivalent form of values fall within the application appended claims limited range equally.
As shown in Figure 1, this adnexa spindle positioning structure, including transitional shell 1, transitional shell 1 horizontal positioned, transitional shell 1 is provided with adnexa main shaft 2, location driver plate 3, positioning key block 4；Location driver plate 3 is connected with adnexa main shaft 2, and adnexa main shaft 2 can be driven to rotate；Location driver plate 3 is offered and is equipped with logical keyway 9, round steel wire cylindrical pressure spring 5 and transverse minor axis 6 it is provided with in the column type hole of positioning key block 4, being provided with alignment pin 7 installing hole in transverse minor axis 6, alignment pin 7 is fixed in transverse minor axis 6 through the waist-shaped hole 10 on positioning key block 4 by the installing hole in transverse minor axis 6.Should ensure that the alignment pin 7 original position at the waist-shaped hole 10 of positioning key block 4, alignment pin 7 inserts in the logical keyway 9 of location driver plate 3, and the rotation of restriction location driver plate 3, namely adnexa main shaft is positioned.Round steel wire cylindrical pressure spring 5 can be applied certain pressure by transverse minor axis 6, and transverse minor axis 6 should touch machine tool chief axis 8 one step ahead than location driver plate 3.
When machine tool chief axis 8 is close, first touch transverse minor axis 6, when axially promoting transverse minor axis 6, alignment pin 7 moves together with transverse minor axis 6, alignment pin 7 exits location driver plate 3, does not affect the rotation of location driver plate 3, and round steel wire cylindrical pressure spring 5 is compressed with certain elastic force；When machine tool chief axis 8 retreats, transverse minor axis 6 moves outward under the elastic force of round steel wire cylindrical pressure spring 5 promotes, alignment pin 7 is driven to enter in the logical keyway 9 of location driver plate 3, prevent the rotation of location driver plate 3, thus fixing adnexa main shaft 2, as long as next time, machine tool chief axis 8 turned in the position specified it is ensured that normally dock with adnexa main shaft 2.
