Specific implementation mode
As previously discussed, largely polishing or " vibropolish " are the mechanically and/or chemically works for being applied to polishing component part
Skill.Vibropolish technique can remove flash removed and keep the surface of the object largely manufactured smooth.Although however, vibrator deburring
Reduce hand labour and can be provided than manual deburring more consistent as a result, still it is mainly only applied to metal parts.
For example, the manufacturer of vibropolish equipment recognizes that metal parts is the major domain for the application of the technology, and recognize big
Amount polishing technology is also used for wood, rubber, stone and plastics.It should be noted that and do not believe that vibropolish be applied to lamination it is compound
Material parts.One the reason is that typical vibropolish medium is not compatible with composite material.It is another the reason is that laminated composite
Part tends to " float " on vibration medium, and itself does not immerse naturally in the medium.In addition, commercial vibropolish
Machine is run with the vibration for being not suitable for the fixed frequency and amplitude of polishing lamination composite material parts.It is thus known that vibropolish
System and method are not only without introduction polishing lamination composite material parts, but also no introduction is can make them appropriate for polishing
The adjustable system of mode of laminar composite part.
Advantageously, as disclosed herein, it has developed for vibrator deburring technique to be applied to laminar composite
The system and method for part.The technology utilization has the automatic vibration of specific deburring medium, specific RPM and processing time
Deburring machine makes these part deburrings, this eliminates the need of the manual single part deburring to many composite material parts
It asks.This saves time, money and eliminate many ergonomic problems being likely to occur using manual deburring.It utilizes
The preliminary test of certain media has been shown that the excellent results that satisfaction is strictly regulated.
Slot class vibropolish device 100 is shown in fig. 1 and 2, such as from Battle Creek Michigan's
Rosler America and other manufacturers are commercially available.Having been used for another commercially available vibratory finishing machine of this kind of technique is
By the model SVP-5 of the Hammond Roto Finish manufactures of Kalamazoo Michigan.The vibratory finishing machine 100 includes
Receive the big basin or slot 102 of the polishing medium being indicated generally at 104 and pending object 106.Slot 102 is supported on spring
On 108 and it is attached to the motor 110 that driving is located in 102 drive shaft 112 below of slot.Drive shaft 112 is attached using bearing 114
It is connected to the spring-loaded slot 102 of peace and is provided with biasing or off-centered counterweight (counterweight, counterweight) 116 so that
Drive shaft 112 is vibrated while rotation, and the vibration is therefore transmitted to slot 102 by bearing 114.This construction makes slot 102
With the frequency depending on 112 rotary speed of drive shaft and the weight depending on counterweight 116 and offset position, (i.e. counterweight deviates center
How much) amplitude vibrate.
As shown in Fig. 2, as represented by arrow 118, the rotation and vibration of drive shaft 112 keep slot 102 elliptical to be as general as
It moves to vibrate.As indicated by arrow 120, this vibration of slot 102 makes the individual particle of polishing medium 104 (be in Fig. 4 A, 4B
136) part 106 and being just polished independently is rotated with the movement of small circle in slot 102, and as indicated by arrows 122, makes institute
There is a large amount of medium 104 to be moved in one direction with " rolling " around trunnion axis while rotating or stirring.
Previously, the vibratory finishing machine of general type as shown in figs. 1 and 2 usually had fixed vibration velocity.It is practical
On, it is basic to can get this kind of vibratory finishing machine with adjustable speed without there is business and all commercially available
Those vibratory finishing machines are run with the speed of 2100RPM.Unfortunately, it due to discussed above, operates at that speed
This kind of vibratory finishing machine is highly ineffective for composite material.
Advantageously, vibropolish system described herein is mutually compatible with composite material, and has developed its fortune
Row parameter, specially vibration frequency and Oscillation Amplitude, and optimize them.In one embodiment, vibratory finishing machine 100
Including both motor RPM controllers 124 and tachometer 126, to allow user to adjust and verify the motor 110 of determining vibration frequency
RPM.Either composite material parts or other types part, this speed regulating mechanism allow user change RPM with
Find the best RPM for polished part 106.If desired, this not only allows for user to find for polishing composite material
The Reasonable Speed of part, and can allow for single vibratory finishing machine be directed to using metal parts, composite material parts and its
The part of his type and be selectively adjusted.
In one embodiment, it has been found that the electric machine frequency of about 2700RPM and the biasing being arranged in drive shaft 112
Counterweight 116 will carry out vibra shoot with the frequency (specific frequency of such as 45Hz) within the scope of 40-50Hz together.It has been found that in this model
It is effective that frequency in enclosing, which is directed to composite material, however the typical 35Hz frequencies of existing vibratory finishing machine are directed to composite wood
Material is invalid.
As illustrated in fig. 1 and 2, vibratory finishing machine 100 can be configured as that counterweight 116 is allowed to increase or decrease to allow to use
Family creates desired biasing, and (in conjunction with selected RPM) is so that vibration has desired amplitude.Those skilled in the art will recognize that
It arrives, vibration frequency is the function of the rotary speed of drive shaft 112, and Oscillation Amplitude is quality and slot 102, the vibration of counterweight 116
The function that medium 104 is compared with the quality that part 106 is formed.In turn, the size and appearance of the characteristic groove 102 of these latter
Long-pending influence.In a kind of test implementation mode, Hammond SVP-5 vibratory finishing machines changed according to the disclosure and by with
In polishing composite material parts.As discussed above, the machine of modification includes the slot with 5 cubic feet of volumes, and is changed
To be operated with 2700RPM.This machine includes four 41/2The counterweight 116 of pound.As shown in Figure 2, these weight increase separately
11/2Pound then provides four 6 pounds of counterweight (in total 24 pounds) and is positioned on the driving shaft by bias.This additional weight is applied
It is added in the satisfactory width for contributing to the deburring medium using lighter weight to provide for deburring campaign in weight mechanism
Degree.
Using the Weighting system of described modification, as shown in dashed circle 140 in fig. 2, it has been found that with driving
Axis is rotated with the speed of 2700RPM, which shows about 10% centrifugal rotation (diameter relative to axis).For example, when rotation
When, it is provided with and the centrifugal rotation movement for describing about 3.3 " (is more than shaft diameter suitable for 3 " diameter drive shafts 112 of counterweight 116
10%).The amplitude vibrated with the frequency of 40-50Hz generates about 0.001 " vibration in individual friction media particle 136.
The amplitude for being considered as the vibration can be adapted to the part of any size and the vibratory finishing machine of any size.It therefore, will be aobvious and easy
See, increased or decreased with the size, volume and quality of vibratory finishing machine 100, the quality of counterweight 116 can also increase or
It reduces to provide desired Oscillation Amplitude with identical vibration frequency.
The spy for being mounted with polishing medium 104 and the slot 102 with the part 106 being polished wherein is provided in figure 3
Write view.Under the vibration motion of slot 102, polishing medium 104 is stirred in slot 102, and tends to show as almost like
In liquid.As the particle of polishing medium repeats to contact its edge and surface, the part 106 being immersed in polishing medium 104
It gradually rolls and rolls in medium, gradually remove flash removed and make rough edge and smooth surface, and also make part
Edge is rounded.
Vibratory finishing machine 100 further includes one or more water inlets 128, which provides the processing water of flowing
To the body block of friction media 104.Water is handled, sometimes with a small amount of mild liquid soap (for example, 30:1 water and soap ratio) one
It rises, incorporates at leisure in medium 104 to provide mobility, some lubricities and washing action to wash off and remove the medium of substrate
Bits and friction particles.As shown in Fig. 2, slot 102 includes outlet or discharge outlet 130 in its relatively low outside and processing water is allowed to drain
Drainpipe 132.The (not shown) such as strainer (strainer), filter (filter) can be placed in drainpipe 132 or
Person is associated with drainpipe 132 to remove medium bits and particle by handling the substrate that water is washed off.Waste water is being discharged it
Before, machine 100, which can be configured as, is deposited to these particles in useless basin (not shown).For adding processing water and associated
The system of useless basin can be the standarized component being generally comprised in commercially available vibropolish system.
As shown in figure 3, individually slot 102 can be provided with spacer 134 so that multiple parts 106 can be in single slot
It is polished simultaneously in 102 independent part.In Fig. 1, spacer 134 is also shown in the slot 102 of polishing machine 100.Root
According to accessory size, shape and during polishing process, whether brought into incidental contact can be tolerated or can be tolerated multiple parts 106 each other
To what degree, multiple parts 106 can be placed on the single of vibropolish slot 102 or be not separated by part or region simultaneously
In, and be polished together.
As described above, polishing medium 104 includes independent friction particles 136.It has been illustrated in figures 4A and 4 B according to this public affairs
That opens can be used in the stereogram of the independent polishing medium particle 136 of debarring process.Polishing medium 104 may include having respectively
The particle 136 of kind shape and size.For example, the particle 136a shown in Figure 4 A has tetrahedron shape, however in figure 4b
The particle 136b shown has cone shape.Other shapes can also be used.These particles 136 are in terms of their full-size
It can be from about 1/4 " to about 21/2" size range in.Other sizes can also be used.As illustrated in figures 4 a and 4b, particle 136
There can be the relatively sharp point or angle 138 in the groove and crack for tending to enter the part 106 being just polished, to make object
It is smooth and get on flash removed and cusp edge in external piece surface.
The particle 136 of polishing medium 104 consists of two parts：Abrasive material and binder.In one embodiment, abrasive material packet
Titanium dioxide is included, and binder is the acrylic acid of synthesis.Medium is about 10%-20% in a more specific embodiment,
Titanium dioxide is maintained in the binder of synthesis Lauxite for the 80%-90% volumes for constituting particle 104.For example, having this
Product labelling SY of the vibropolish medium of kind ordinary preparation in the Vibra-Finish Co. from California, Los Angeles
Under be commercially available.
As disclosed herein, for the vibropolish of composite material parts, it is considered desirable to be polishing medium ratio
Weight is from about 1.5 to 2.0 so that the sectional density of the total volume of particle 136 is nearly equal to polished laminated composite zero
The sectional density of part 106.This aspect of vibropolish medium 104 allows 106 nature of composite material parts, and " (sink sinks for infiltration
Leaching) " in the medium, rather than " floating " is on it, therefore part is allowed substantially to immerse in the medium.
This media formulations are different from the reference fluid generally used for polishing metal and other parts.Specifically, perhaps
More vibropolish media formulations use aluminium oxide as the abrasive material generally incompatible with composite material.On the other hand, it has been found that
Titania abrasive preferably works with composite material parts.However, it is considered that before and it is unaware of for composite material
The suitability of this kind of friction media.In addition, the binder as synthetic need not be directed to the change of any processing of polishing process
Close object (for example, soap).Instead, treatment liquid can be light water, leave soapless part, and last in technique only receives
Water rinses and towel blots.
The friction particles 136 of medium 104 are generally constant composition throughout their volume, therefore work as each particle
136 with using when gradually wearing out, or even when it changes shape and size, its surface also keeps identical frictional property
Matter.That is, during use, the surface of friction particles 136 will be gradually worn out, and be exposed with substantially the same frictional property and spy
The subsurface material of property.In this way, friction particles 136 are during use as they gradually wear out and keep their operating characteristic,
Until they are to be considered it is expected to replace their size with new, full-scale particle.By being periodically added into new particle
136 can effectively complete replace wear particle 136, to maintain bigger full-scale particle given percentage.
The surface for seeming slightly to polish is generated using the vibrator deburring technique of the polishing medium on the composite.Make
It is to provide edge on part to weaken to an additional aspect of part vibrator deburring with device and method disclosed herein
Or edge slows down.Well known during manufacturing to be, the sharp side on machine components is undesirable in many cases, but
The natural by-product of various manufactures and/or machining processes.What is be shown in FIG. 5 is the end 202 of composite material parts 200
Partial section view.Before deburring, the end 202 of part 200 includes sharp side 204.According to the vibropolish of the disclosure it
Afterwards, it is circular contour 206 to make sharp side 204 smoothly.Desired edge weakens (edge break) or edge slows down (edge
Relief degree) will change from a kind of situation to another situation.Using system and method, edge weakens or about 0.005 "
Circular arc can be arranged in the exposed edge of composite material parts.It is evident that the amplitude that edge weakens will at least partly
Ground depends on the abrasive levels of the length and friction media 104 of vibration processing.
The method for deburring and polishing lamination composite material parts summarized according to the disclosure is provided in figure 6
The logical flow chart of step in 500 embodiment.First, the slot of bobbing machine is filled with polishing medium particle (step 502).
Consider that desirably filling slot no more than about 80% expires volume, but is no less than about 50% full volume.Next, opening processing water
Flow (step 504).Processing water can be the light water of no any additive (soap etc.).It handles water washing and is detached from polishing
The fragment of media particle body block, by removal have disengaged from the residue of part enhance polishing process and remove have disengaged from throwing
The friction dust of optical medium particle.Processing flow for the technique is typically used for the pact of the flow of vibropolish metal parts
Twice of amount.It is generally thought that polishing medium volume 0.35-0.50 gallons per hour per cubic foot of processing water can be used
Stream.In one embodiment, using the slot with 5 cubic foot volumes, 2 gallons per hour of processing flow has been used.
After handling water flowing, machine (step 506) can be started, that is, can start to vibrate with desired frequency.
Next, waiting for that the part of deburring can be placed to (step 508) in the slot of polishing machine, and so that the part is immersed in polishing and be situated between
In matter.It has been found that being damaged caused by being desirably in contact with each other in order to avoid part and/or part being avoided not to be sufficiently polished, put
The volume of part set in slot is no more than about the 10% of slot total volume.Then, part stays in vibra shoot within the set time
(step 510), while technique is carried forward.In one embodiment, it has been found that can be with good result treatment part about
60 minutes.It is generally thought that the vibropolish for about 45-60 minutes may be sufficient.Those skilled in the art will be true
Surely the best setting of any given part and combination of media is directed to provide desired edge weakening and surface treatment.
Part it is abundant processing after, the part (step 512) of polishing can be removed from machine advantageously it is possible to from
Part is removed in slot and runs machine simultaneously, this, which can aid in, accelerates batch processing stream.Alternatively, before the removal of part or
It later, being capable of closing machine and processing flow (step 514).After the treatment, new water can be utilized to rinse part (step
516) and it is dry, make them prepare to use.Entire laminated composite part will show the label of deburring, on part
Slight blunt, polishing appearance is left, and is especially obvious (that is, keeping shape or " work in " tool side " of part
Tool " and the simultaneously avris of processed composite material parts).It is compound compared to the part handled in a manner of disclosed herein
The tool side of the non-deburring of material parts will seem glossy.In this way after polish parts or a collection of part,
If desired, work can be repeated by one of being placed into (step 508) in slot by more parts or being back to previous steps
Skill.As previously discussed, polishing medium particle 136 is gradually worn out with using.As a result, it is desirable to by removing certain relatively low
Threshold size particle below and with may compare volume new particle replace removal particle come be updated periodically vibration
Medium (step 518) so that particle size distribution is kept in the desired range.This can be by toppling over all particles from slot
To according to the size selection of the strainer used go out the vibration filtering net mechanism (not shown) in certain sizes all particles below come
It completes, therefore removes minimum particle.Slot can be returned in terms of size than the remainder particulate of the strainer bigger used to relay
It is continuous to use, and the new particle (or particle of suitable size) of certain volume can be placed in slot so that particle volume returns to the phase
Level (the step 502) of " full " hoped.In one embodiment, the update for vibrating media particle is related to existing in terms of removal size
About 1/2 " particle below, and utilize 1 " to 21/2" particle of comparable volume of size replaces them.
Technique disclosed herein by the machine operating parameter that will specifically develop and processing time with it is specific and unique
Vibropolish media formulations are combined and are possibly realized, to allow specific deburring medium to be applied to composite substrate.It crosses
It goes in composite material industry, it is believed that because how to use the technology of friction media reason on composite substrate without exploitation
Solution, so being not attempt to this kind of technique.
Automatic batching processing, the removal that device and method provide composite material parts appear on exterior part surface
Burr.The use of automatic polishing allows many part batching processing, eliminates the human error on burr and reduce or eliminate
The often possibility of ergonomic problem associated with manual deburring, such as complication of wrist.Technique disclosed herein
Made largely again with the potentiality and progress for saving plenty of time and money and by progress by providing more cost efficiencys
The safety method of condensation material part deburring.Height is reduced by the way that the manual deburring concentrated by hand is changed into automatic equipment
