Description
Technical field
The present invention relates to a kind of Hub fixture, more particularly, to a kind of six equal portions bail fixture of automotive hub outer ring.
Background technology
Fixture is needed in wheel hub process, and common automotive hub fixture includes folder wheel hub being positioned on lathe
Tool, this fixture method of clamping is than stronger, but adjustable range is small, it is necessary to manually replace different clamping radiuses, adapts to
Energy force difference, it is troublesome in poeration, and the more thick and solid heaviness of this fixture.Chinese patent discloses a kind of wheel hub turning and polishing recruitment
Clamps（Authorization Notice No.：CN203649426U）, including discoidal fixed seat and wheel hub blank, the structure of centralized positioning seat
Positioning seat centre bore to be formed on positioning seat column, on positioning seat column using the center of circle of positioning seat centre bore in
Thimble shape array distribution has several plug tenons, centralized positioning seat with discoidal fixed seat is concentric be fixed by screws in together with；
Annular array is distributed six locating pieces centered on the center of circle of fixed seat in fixed seat, and locating piece is fixed by screws in fixed seat
On, locating slot is formed on locating piece, the top sleeve of the process area of wheel hub blank in locating slot, taking turns by plug tenon sleeve
In the recess of hub blank；Spinning cylinder is fixed by screws in the lower part of fixed seat, and the piston rod of spinning cylinder stretches out fixed seat
Upper surface, the briquetting of " L " shape is fixed with the piston rod of spinning cylinder, briquetting is pressed on process area；Locating slot is arc
Shape strip slot, two sides of locating slot have been separately formed slot left tilted surface and slot right tilted surface, and the top of process area forms work
Skill platform left tilted surface and process area right tilted surface, process area left tilted surface and process area right tilted surface are right tiltedly with slot left tilted surface and slot respectively
Face is engaged.But this fixture clamping face when clamping wheel hub outer ring is generally forging plane, forging plane surface roughness is big, and
There is ellipse, hence in so that the outer ring product parallel error processed is poor, product rib circle, ellipse are bad, and product easily folder is inclined.
The content of the invention
The present invention is to provide a kind of six equal portions bail fixture of automotive hub outer ring, it is mainly solved present in the prior art
Fixture be generally forging plane in clamping face when clamping wheel hub outer ring, forging plane surface roughness is big, and has ellipse, hence in so that
The outer ring product parallel error processed is poor, product rib circle, oval bad, the technical problem that product easily folder waits partially.
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals：
The six equal portions bail fixture of automotive hub outer ring of the present invention, including chuck, is evenly equipped with three sliding slots on the chuck, often
A gripping dogs are all slidably connected in bar sliding slot, gripping dogs include claw body, and the inner of claw body is connected with
The segmental arc of automotive hub outer ring outer surface can be surround, the inner surface of each segmental arc is equipped with two bails, table in segmental arc
The top in face is equipped with inclined-plane.The present invention is clamped in gripping dogs increases bail on face, that is, segmental arc, bail is distributed for six equal portions, folder
Tight face is by traditional face（Line）Contact is improved to point contact.Therefore clamping workpiece of the present invention is convenient, safe, quick, can mitigate work
The labor intensity of people, product quality are stablized, and rejection rate declines.Since the top of segmental arc inner surface is equipped with inclined-plane, putting
When putting wheel hub outer ring, the upper surface of segmental arc will not touch wheel hub outer ring, so as to avoid abrasion is produced.
Preferably, the sliding slot is T-shaped groove, sliding block, the claw body of gripping dogs are slidably connected in sliding slot
It is connected by connector with sliding block.Sliding block can slide in sliding slot, so as to drive claw body to be moved, sliding block can connect
The transmission mechanisms such as screw are connect, are moved under the control of cnc mechanism.
Preferably, being provided with caulking groove on the inner surface of the sliding slot, caulking groove is the strip being spaced apart, and caulking groove embeds
Equipped with rubber bumper.One rubber bumper is all set at a certain distance inside sliding slot, and this rubber bumper is
Type is chosen to install, so whole fixture can play positioning, spacing effect at the wheel hub outer ring of clamping different size, ensure that dress
The accuracy of folder, while prevent and can be rocked during clamping, it ensure that the accuracy of processing.
Preferably, be provided with positioning screw hole on the chuck, positioning screw hole internal thread is connected with locating rod, in locating rod
End is connected with set screw, and the inner of set screw is connected with locating piece, and the inner surface of locating piece is arc.Gripping dogs are in cunning
After being slided in groove, it clamps wheel hub outer ring, can in processing due to being to be flexibly connected in itself between sliding slot and gripping dogs
Small displacement can be produced, cause processing inaccurate.Therefore the present invention, can be in positioning screw hole after gripping dogs clamping
Locating rod is inserted into, while is withstood on locating piece on the outer surface of gripping dogs by set screw, can not only so increase folder
Clamp force, moreover it is possible to prevent the vibration due to processing generation so that gripping dogs shift.
Preferably, the bail is connected with adjustable column, adjustable column, which is worn, to be connected in the regulating tank that segmental arc opens up, and is adjusted
Groove is inner to be equipped with pressure sensor and adjusts spring.It can increase the pressure of bail using spring is adjusted, and can prevent
Only it wears the outer surface of wheel hub outer ring.The pressure held out against can be monitored at any time using pressure sensor, so that according to numerical control machine
The parameter set on structure, the position of adjust automatically gripping dogs, ensures that wheel hub outer ring is clamped under suitable pressure, reduces quilt
The probability of damage.
Preferably, the inner surface of the chuck is equipped with arc skewed slot, multiple steps are provided with arc skewed slot, arc is oblique
Groove is connected with turntable.Arc skewed slot on chuck can be used for installing turntable, and it is oblique turntable can be connected to arc using rotation
In the step of groove, assembling is relatively simple, and step can be multiple, can so adjust the height of whole chuck.Set on turntable
There is the fixation convex block that can be connected in arc skewed slot.The direction of rotation of turntable is consistent with the setting direction of arc skewed slot, ensures not
It can disengage.
Therefore, the present invention increases bail on gripping dogs clamping face, and bail is distributed for six equal portions, clamps face by traditional
Face（Line）Contact is improved to point contact, this fixture clamping workpiece is convenient, safe, quick, can mitigate the labor intensity of worker, product
Stable quality, rejection rate decline, and by multiple detent mechanisms, and carry out pressure monitoring automatically, ensure that the processing essence of product
Degree, it is simple and reasonable for structure.
