Description
Technical field
The invention belongs to helical milling processing technique field, relate to a kind of for new material such as composite,
Automatically the helical milling device and the method for work thereof that adjust aperture of the difficult-to-machine material such as aluminium alloy, titanium alloy.
Background technology
Helical milling be aviation occur for the difficult-to-machine material drilling such as composite, titanium alloy
New technique.The new material such as composite, titanium alloy is owing to having excellent mechanical and physical performance and by a large number
Apply in Flight Vehicle Design, manufacture the structure member such as eyelid covering, support beam.This quasi-structure component is at aircraft
Need during assembling to process substantial amounts of connecting hole, such as rivet hole, bolt hole etc..Composite, titanium alloy
Belonging to typical difficult-to-machine material, employing Twist Drill is the system that current Aero-Space manufacturing enterprise is the most frequently used
Hole method.When composite is used fluted drill drilling, axial force is relatively big, easily occur layering, tear,
The manufacturing deficiency such as spike protein gene, burr, tool wear is serious, and machining accuracy is low.Titanium alloy material is used
During fluted drill drilling, easily producing burr in outlet, cutting temperature is high, and heat affecting is serious, and cutter is anxious
Acute abrasion, hole wall by the friction and Extrusion effect of continuous chip, precision and of poor quality.When carrying out aircraft machine
When the wing is from fuselage docking or the docking of fuselage different cabin section, need to gather into folds composite and titanium alloy sieve formation
Composite/alloy stack structure, carries out integral type drilling.Owing to bi-material performance difference is big, cutter shape
Shape and machined parameters are difficult to mate, and processing bore dia and the degree of depth are greatly, and crudy requires height, drilling difficulty
Increase further.For solving the problems referred to above, it is ensured that drilling precision and quality, have at present use refinement work
The method of skill, by boring, expanding, the series of processes such as hinge just can be finally completed the processing in a hole, technique stream
Journey is long, and it is low to become to produce efficiency, needs tool category many, and follow-up work when the damage that produces of front one technique is serious
Skill can not be completely eliminated.On the other hand, aircraft erecting yard is many is used hand-held pneumatic drill instrument to carry out by workman
Processing, can produce a large amount of harmful dust during machining composite material, the working environment of workers is severe；Machining titanium alloy
Time need to apply the biggest axial compressive force with hands, labor strength is big.
Helical milling technology occurs to solve the problems referred to above.Helical milling belongs to for conventional borehole
In eccentric processing process, special-purpose milling cutter revolves round the sun around center, processed hole while rotation, and at axis direction
Upper feeding, the track of center cutter is no longer straight line but helix.Existing academic research and engineering practice
All it turned out, helical milling has more advantage relative to conventional borehole: be difficult to out during machining composite material
Now be layered, tear, the manufacturing deficiency such as spike protein gene, burr；During machining titanium alloy, gateway all will not produce
Burr；Cutting force is little, and cutting temperature is low；Chip is discontinuous and has natural chip space；Can be by adjusting
Whole bias changes aperture without changing cutter.These advantages of helical milling make it process in aviation difficulty
Material and widely field have huge application prospect.
Process to realize the helical milling of aircraft erecting yard, it is necessary to develop special helical milling device.
The helical milling device occurred is broadly divided into two classes.One class is adopted and is manually adjusted bias
Amount." method for helically milling hole and device thereof ", Chinese patent as disclosed in Chinese patent CN200910068518
