Description
Technical field
The present invention relates to a kind of mechanical equipments, relate in particular to a kind of equipment of aluminum-alloy wheel burr brushing.
Background technology
Since many merits, the aluminum-alloy wheels such as weight is strong, good heat dissipation, handsome in appearance, intensity is high are widely used,
China also becomes the country that aluminium alloy wheel hub yield is most in world wide.
Currently, the manufacturing process according to aluminum-alloy wheel is classified, there are three types of manufacturing methods, i.e. casting vehicle for aluminum-alloy wheel
Wheel, forging wheel, casting rotation wheel.It is according to aluminium ingot melting, rough-cast, mechanical processing, surface spraying, finished product packet to cast wheel
What the processes such as dress were manufactured, forging wheel is according to works such as bar cutting, spinning, mechanical processing, surface spraying, finished product packings
What sequence was manufactured, casting rotation wheel is according to aluminium ingot melting, rough-cast, spinning, mechanical processing, surface spraying, finished product packing
Etc. processes manufactured.
No matter which kind of above-mentioned manufacturing method, due to the shear action of lathe tool, is closed after wheel completes mechanical processing in aluminium
The window position of golden wheel back of the body chamber, inevitably generates burr not of uniform size, and these burrs have to removal.
Currently, the conventional mode of flash removed of going is by dedicated burr brush shown in Fig. 1 clean with water.Burr brush
It is made of the nylon yarn containing abrasive material, this kind of mode goes flash removed significant effect, but has the following problems：1, burr brush
Kind is extremely more.This is because wheel kind is hundreds and thousands of, wheel back cavity structure is had nothing in common with each other, it is therefore desirable to be carried on the back chamber according to wheel and be made
Type makes special burr brush, and scene is also required to prepare a variety of burr brushes；2, auxiliary material wastes.Burr brush is integrally fixed on substrate,
After the failure of burr brush, substrate can only be abandoned, and have no value for use；3, brush filament utilization rate is low.Since wheel back of the body chamber is the structure of recess,
After burr brush is scrapped, it is certain to some remaining brush filament.Meanwhile brush filament also needs in implantation substrate, this part brush filament
It is also no any use value.In general, the waste rate of brush filament reaches 10%-20% or so；4, replacing construction occupies life
Produce beat.After the failure of burr brush, it is necessary to shut down and replace, this will occupy productive temp.
Invention content
The invention aims to provide a kind of aluminum-alloy wheel burr brushing equipment.
To achieve the goals above, the technical scheme is that：A kind of aluminum-alloy wheel burr brushing equipment, by pedestal,
Guide post, upper platen, motor, Hub fixture, sliding platform, feeding cylinder, locking cylinder, tapered sleeve, brush wire bundle, supporting plate, brush wire bundle
Positioning disk, balance weight iron composition.Pedestal and column, upper platen fit together, and form the main body of whole equipment, and motor is mounted on upper
On platen, Hub fixture is fixed on motor, and can be rotated with aluminum-alloy wheel under the drive of motor, and cylinder is fed
It is fixed on the base, sliding platform can be driven to be moved up and down under pressure along guide post, brush wire bundle positioning disk is fixed on
On sliding platform, brush wire bundle upper end passes through brush wire bundle positioning disk, lower end to be jacked up by supporting plate, and supporting plate is connected by stone dead wire and balance weight iron
It connects, locking cylinder is fixed by the bracket on brush wire bundle positioning disk, locking cylinder energy band mantle set operation up and down, to squeeze brush
Tow positioning disk is allowed to generate flexible deformation, achievees the purpose that be clamped and loosens brush wire bundle, and brush wire bundle is made of multiply brush filament,
Outside stretch wrap film, in order to take.
Before work, as shown in Fig. 2, locking cylinder holds out against tapered sleeve, brush wire bundle positioning disk is set to generate flexible deformation, by brush filament
Beam is clamped by brush wire bundle positioning disk.At this point, feeding cylinder is in retracted mode.
Then, aluminum-alloy wheel is placed in Hub fixture by artificial or manipulator, and is clamped.
Then, locking cylinder loosens, and tapered sleeve moves down naturally.Brush wire bundle positioning disk is rapid to return under the action of natural resiliency
Shape is restored, and unclamps brush wire bundle.At this point, under the action of balance weight iron, balance weight iron drives supporting plate, and then drive by stone dead wire
Brush wire bundle is run rapidly upward, and brush wire bundle is fitted tightly over aluminum-alloy wheel and carries on the back chamber（Fig. 3）.
With that is, locking cylinder is run up, tapered sleeve is held out against, so that brush wire bundle positioning disk is generated flexible deformation, brush wire bundle is made to press from both sides
It holds in brush wire bundle positioning disk.
Then, motor drives Hub fixture, and then aluminum-alloy wheel is driven to be rotated.Cylinder is fed in certain pressure to make
Reach the work of flash removed with lower upward jacking sliding platform to make brush wire bundle tightly be fitted in the back of the body chamber of aluminum-alloy wheel
With.
Brush wire bundle is made of multiply brush filament, in the outside stretch wrap film of brush wire bundle, as indicated at 4.When work, film meeting
It is rapid to tear under the turning effort of wheel, and expose brush filament.With the progress of work, brush wire bundle can be gradually worn out.Work as brush filament
It, can whole replacement after beam may wear to the limit.
The present invention can meet the needs that aluminum-alloy wheel manufacturing enterprise removes machining operation flash removed, can play reduction
Cost reduces that inventory, compatibility is strong, reduces the effect for replacing beat, while having that simple in structure, failure rate is low, performance is stablized
The characteristics of.
