Description
Technical field
The invention belongs to hole machined technical fields, and in particular to the common process and ultrasonic vibration precision in hole on cylindrical structure
Processing method.
Background technique
There is cylindrical structure on many machine components, to drill on these cylindrical structures in many situations, and often want
Ask the axis in the hole to intersect perpendicular to cylinder axis, and with cylinder axis, the surface in the diameter in hole and hole slightly degree of wiping to meet compared with
High requirement.
The hole on cylindrical structure is processed, may relate to multiple working procedure, but key step related to the present invention are as follows:
First, prepare blank, blank has cylindrical structure；Second, it drills on cylindrical structure；Third, to what is drilled out
Hole, carries out following process, and the technological approaches that may be taken has reaming, fraising, bore hole, extruded hole, internal grinding, grinding etc..
It is difficult to guarantee the machining accuracy in hole well using the prior art, is especially difficult to ensure the hole and cylindrical structure axis
The verticality and symmetry of line.
Summary of the invention
The purpose of the present invention: for the requirement for processing hole on cylindrical structure, the processing method for proposing a kind of hole prevents institute
Correct position is deviateed in the hole of processing, improves the machining accuracy in hole.
In the prior art, lead to common drill bit directly drill on blank, feature of the present invention first is that: in blank hole portion to be drilled
Position, first processes a facet, then drills on facet.When the prior art drills, drill bit connects with periphery first
Touching, drill bit are easy deflection correct position, and when present invention drilling, drill bit is contacted with facet first, and drill bit is not easy deflection.Have
Conducive to the verticality and symmetry for guaranteeing processed axially bored line and cylindrical structure axis.
Fig. 1 is the schematic diagram that the present invention drills.Fixture is installed on lathe 1 in figure, fixture mainly include setting element 2,
Clamping element 6, fixing element 3.Workpiece 4 determines position by setting element, is clamped members clamp.5 be drill bit, and 7 is to be added
The hole of work.
The initial profile of 4 cross section of workpiece is circle, but the profile in Fig. 1 is not round, the horizontal dashes on profile top
Representative is processed into facet herein.
The present invention emphasizes: before drilling, at the position that will be drilled, a facet is processed with milling cutter, facet
Area is less than the cross-sectional area in hole to be processed, and the profile of facet corresponds to hole cross-sectional profiles to be processed.It can also use
Grinding, planing or other methods process facet.In order to improve processing efficiency with reduce cost, can be primary when processing facet
The multiple workpiece of clamping so that time processing goes out multiple facets, such as once mill out facet on multiple workpiece.
Secondly, in the present invention, drill bit is designed as stairstepping, when drilling enters the part of inside workpiece, diameter etc.
Diameter in the hole for needing drilling does not enter the part of inside workpiece, has a diameter larger than the diameter for needing the hole of drilling, in this way may be used
The overall stiffness for improving drill bit, prevents bit deflection.
Again, in the present invention, by clamping element, for example, 6 in attached drawing, it is designed as split type structure, it is straight with cylindrical structure
The part of contact can rotate, and be floating platen.Since floating part can adapt to cylindrical structure automatically, so, clamping process
In, workpiece will not be made to leave the correct position determined by setting element because of clamp operation.
Finally, improving the wearability of setting element.Make setting element and workpiece contact portion position that there is wear-resistant coating.Wear-resisting painting
Layer is the refractory metal or nonmetallic compound good using a thin layer wearability of vapor deposition method coating.Coating has surface
The characteristics such as hardness height, the good, stable chemical performance of wearability.
When required precision when hole is very high, ultrasonic vibration mill processing realization can be used to the Precision Machining of inner hole.
Fig. 2 is the schematic diagram in the present invention ultrasonic Precision Machining hole.8 it is milled portion in figure, 9 is integrated form amplitude transformer, 10
Represent ultrasonic vibration, 11 be energy converter, 16 be ultrasonic mill bar.
Ultrasonic precise processing device is connected by conjugation handle 13 with common mill machining tool, adds the cooling of utilization of hour liquid, profit
It is sliding.Bore area quality can be improved using Vltrasonic device.
In order to guarantee processed hole perpendicular to the axis of cylindrical structure matrix, and intersecting therewith, people are typically easy to expect
And the technical solution having been carried out have it is following several:
First, in drilling, guide sleeve, guidance and steady drill bit are set；Second, improve setting element and clamping element
Machining accuracy.Third, using other technique and skills.
Recently, the present inventor is inadvertently, it is contemplated that the technical solution in the present invention.Obviously it is processed on periphery
It after one facet, then drills, drill bit is not easy partially.And in prior art, it directly drills in periphery, drill bit is to hold
Easy deflection.
Technical solution of the present invention is simultaneously uncomplicated, but does not allow to be readily conceivable that.Caochong weighing elephant described in The Romance of the Three Kingdoms
Method is also fairly simple, but does not also allow to be readily conceivable that, therefore affirmed, can spread extensively and for a long time.
In conclusion the present invention has following novelty:
The common process in hole and ultrasonic vibration precision processing method on cylindrical structure, which is characterized in that be equipped on lathe
Fixture, fixture include setting element, clamping element, and there is wear-resisting painting in the part contacted on setting element surface with cylindrical structure outer circle
Layer, the part that clamping element is contacted with cylindrical structure outer circle are floating structure, and drill bit is stairstepping, ultrasonic Precision Machining dress
It is equipped with integrated form amplitude transformer, energy converter；Procedure of processing are as follows: first, prepare blank, the position for needing to process hole on blank is cylinder
Shape structure；Second, before drilling, process facet in the cylindrical structure outer circle that will be drilled, the area of facet be less than to
The cross-sectional area in hole is processed, the position of facet corresponds to the position in hole to be processed；Third, drilling, drill axis perpendicular to
Cylindrical structure axis；4th, to the hole drilled out on cylindrical structure, finished；5th, it is processed on cylindrical structure
Hole, carry out ultrasonic vibration precision processing.
Beneficial effects of the present invention: first, the present invention is easily guaranteed that processed hole, perpendicular to cylindrical structure, and it is opposite
It is symmetrical in cylindrical structure.Second, tool stiffness is improved, cutter distortion is reduced.Third, setting element are contacted with cylindrical structure
Part have wear-resistant coating, wearability is good.4th, floating structure can guarantee that clamping element comes into full contact with workpiece.5th, it adopts
Precision Machining is carried out with ultrasonic vibration, the surface quality in hole can be improved.
