Abstract
The utility model discloses a kind of twin-roll jaw means, include rotating disk, the rotating disk is provided with multiple claws, the claw includes base, the front end of the base is provided with inner roller claw and outer roller claw, the inner roller claw mutually staggers with outer roller claw, and the distance between the inner roller claw and outer roller claw are more than the diameter of roller.The utility model on a claw by being arranged side by side two roller claws so that when clamping tubule, the contact area of chuck and tubule is bigger, in the case where not increasing clamping force so that clamping is more firm.
Description
Technical field
It the utility model is related to the claw structure of a kind of chuck structure, particularly pipe cutting machine.
Background technology
During using laser cutting tubing, usual laser head is not taken exercises axially relative to tubing.The axial movement of tubing and
Laser cutting head realizes the processing purpose of various patterns perpendicular to the plane motion of tubing axis.In cutting, it is necessary in tubing
Tail end install rolling clamp additional and drive tubing rotation, and rolling clamp drives in the presence of a power set in itself
Tubing axially moves, and realizes the purpose of cutting.Therefore, when long pipe material is cut, except tubing tail end needs a rotation
Turn fixture（Active fixture）Outside, in the process side close to laser cutting head, an auxiliary hollow clamp is also needed（There is rotary power
Or irrotationality rotatory force）, keep tubing to be cut the positional precision at end.
When cutting non-round, auxiliary hollow clamp is typically clamped using chuck.Changing tubing or change
, it is necessary to open and adjust the opening of four paws during cutting material size, realize more conversion materials and adjust the purpose of size.At present,
In chuck, when some calibers less tubing is clamped, because the contact area of tube wall and claw is small, easily cause to press from both sides
Shakiness is held, or claw overexerts and damages tubing.
Utility model content
The technical problems to be solved in the utility model is：There is provided a kind of clamping more steady claw structure.
The solution that the utility model solves its technical problem is：A kind of twin-roll jaw means, include rotating disk, institute
State rotating disk and be provided with multiple claws, the claw includes base, and the front end of the base is provided with inner roller claw and outer rolling
Cylinder claw, the inner roller claw mutually staggers with outer roller claw, between the inner roller claw and outer roller claw away from
From the diameter more than roller.
As the further improvement of above-mentioned technical proposal, the claw has four, and four claws, which are evenly distributed on, to be turned
On the upper and lower, left and right of disk, and inside and outside between adjacent claw two-by-two stagger.
As the further improvement of above-mentioned technical proposal, also include first driving means, the second drive device, described
One drive device drives upper and lower claw synchronizing moving；Second drive device drives left and right claw synchronizing moving.
As the further improvement of above-mentioned technical proposal, the inner roller claw is directly anchored on base, the outer rolling
Cylinder claw is bolted on base.
As the further improvement of above-mentioned technical proposal, the outer roller claw includes connecting plate, on the connecting plate
Provided with elongated hole, the bolt is connected through elongated hole with base.
The beneficial effects of the utility model are：The utility model on a claw by being arranged side by side two roller cards
Pawl so that when clamping tubule, the contact area of chuck and tubule is bigger, in the case where not increasing clamping force so that
Clamping is more firm, and narrow tube deformation is small, and cut lengths precision is high.
Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
The accompanying drawing to be used is briefly described.Obviously, described accompanying drawing is part of the embodiment of the present utility model, rather than entirely
Portion's embodiment, those skilled in the art on the premise of not paying creative work, can also obtain it according to these accompanying drawings
His design and accompanying drawing.
Fig. 1 is schematic perspective view of the present utility model.
Embodiment
Design, concrete structure and caused technique effect of the present utility model are carried out below with reference to embodiment and accompanying drawing
Clearly and completely describe, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is part of the embodiment of the present utility model, rather than whole embodiments, based on embodiment of the present utility model, the skill of this area
The other embodiment that art personnel are obtained on the premise of not paying creative work, belong to the model of the utility model protection
Enclose.In addition, all connection/annexations being previously mentioned in text, not singly refer to component and directly connect, and refer to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, to form more excellent draw bail.Each technology in the invention is special
Sign, can be with combination of interactions on the premise of not conflicting conflict.
Reference picture 1, a kind of twin-roll jaw means, include rotating disk 1, the rotating disk 1 is provided with multiple claws 2, described
Claw 2 includes base 21, and the front end of the base 21 is provided with inner roller claw 22 and outer roller claw 23, the inner roller
Claw 22 mutually staggers with outer roller claw 23, and the distance between the inner roller claw 22 and outer roller claw 23 are more than roller
Diameter.By being provided with two roller claws on a claw, effectively increasing claw has the contact area of tubule, and
And a certain distance that staggers between two roller claws so that clamping is more stable.
Preferred embodiment is further used as, the claw 2 there are four, and four claws 2 are evenly distributed on rotating disk 1
Upper and lower, left and right on, and inside and outside between adjacent claw two-by-two 2 stagger.When claw needs to clamp tubule, due to interior
Staggered distance between outer two rollers so that when clamping, the inner roller claw or outer roller claw of adjacent claw
It is inserted between internal and external cylinder claw, avoids the generation for occurring interfering, and eight roller claws of four direction are tight
Close is close together so that clamping is more solid and reliable.
Preferred embodiment is further used as, also includes first driving means（Do not regarded in figure）, the second drive device
（Do not regarded in figure）, the upper and lower synchronizing moving of claw 2 of the first driving means drive；Second drive device drives left and right card
The synchronizing moving of pawl 2.Four claws are driven to realize Double-linkage by two drive devices so that the centring property of chuck is more preferable, dress
The precision of folder is higher.
Preferred embodiment is further used as, the inner roller claw 22 is directly anchored on base 21, the outer rolling
Cylinder claw 23 is bolted on base 21.
Preferred embodiment is further used as, the outer roller claw 23 includes connecting plate, set on the connecting plate
There is elongated hole, the bolt is connected through elongated hole with base 21.By elongated hole, the peace of outer roller claw can be suitably adjusted
Holding position, improve the convenience and adaptability used.
Better embodiment of the present utility model is illustrated above, but the invention be not limited to it is described
Embodiment, those skilled in the art can also make a variety of equivalent changes on the premise of without prejudice to the utility model spirit
Type or replacement, these equivalent modifications or replacement are all contained in the application claim limited range.
