Speed rotation, and the first conveying roller 5 and 5 ' constant speed rotation of the second conveying roller are driven, straight-line motion mechanism 3 is driven by connecting rod
Etc. speed ratios sector gear moved synchronously to 42 and 42 ', drive work shaft gear 20 and 20 ', the first conveying roller 5 and second to convey
Roller 5 ' is swung around the centre of gyration O and O ' simultaneously, and roll gap A's opens between the first conveying roller 5 of drive and the second conveying roller 5 '
Variation is closed, realizes that the first conveying roller 5 and the second conveying roller 5 ' clamp and transport strip material 6.
As shown in figure 4, for the comparison scheme of present invention clamping device synchronous with multi link:
In the mechanism, the speed ratio of countershaft-gear 10 and 10 ' is identical, is constant speed drive.Furthermore countershaft-gear 10 is also simultaneously
It being engaged with work shaft gear 20, countershaft-gear 10 ' is engaged with work shaft gear 20 ', realization work shaft gear 20 and 20 ' etc.
Speed rotation, and drive the first conveying roller 5 and 5 ' constant speed rotation of the second conveying roller；In the mechanism, set at rolling centerline
A hinge joint C is set, hinge joint C is the symmetrical centre of multi link synchronization mechanism 40, and straight-line motion mechanism 3 is synchronous by multi link
Mechanism 40 drives work shaft gear 20 and 20 ', the first conveying roller 5 and the second conveying roller 5 ' simultaneously around the centre of gyration O and O '
It swings, to drive the opening and closing variation of roll gap A between the first conveying roller 5 and the second conveying roller 5 ', realizes the first conveying roller
Son 5 and the second conveying roller 5 ' clamp and transport strip material 6.
As shown in figure 5, for the comparison scheme of present invention clamping device synchronous with symmetrical connecting rod:
The clamping device is made of two identical slider-crank mechanisms that same driving source drives.In the mechanism,
The speed ratio of countershaft-gear 10 and 10 ' is identical, is constant speed drive.Furthermore countershaft-gear 10 is also nibbled with work shaft gear 20 simultaneously
It closes, countershaft-gear 10 ' is engaged with work shaft gear 20 ', realizes 20 and 20 ' constant speed rotation of work shaft gear, and drive first
5 ' constant speed rotation of conveying roller 5 and the second conveying roller；Straight-line motion mechanism 3 is set at horizontal center line simultaneously, by right
Claim the realization of connecting rod 41 and 41 ' to move synchronously, drives work shaft gear 20 and 20 ', the first conveying roller 5 and the second conveying roller 5 '
It is swung simultaneously around the centre of gyration O and O ', to drive the opening and closing of roll gap A between the first conveying roller 5 and the second conveying roller 5 '
Variation realizes that the first conveying roller 5 and the second conveying roller 5 ' clamp and transport strip material 6.
As depicted in figs. 1 and 2, working principle of the present invention is as follows: drive lacking link-type pinch mechanism of the invention be
On the basis of the synchronous clamping device of Fig. 4 multi link formula, 1 horizontal direction is increased to the second hinge joint C at former rolling centerline
Freedom of motion, and with the first holddown spring 71 and the second holddown spring 72 to the horizontal initial position of the second hinge joint C point
It is limited.Roll gap A on-off action is driven by straight-line motion mechanism 3, drives 2 He of third gear by multi link synchronization mechanism 4
4th gear 2 ' is rotated rotating around the centre of gyration O and O ', drive respectively with coaxial first defeated of third gear 2 and the 4th gear 2 '
Send roller 5 and the second conveying roller 5 ' synchronous hunting, the movement of roll gap A synchronous opening/closing is realized by multi link synchronization mechanism 4.Work
When roll gap need to open in advance, when upstream metal detector detects that material enters roll gap moment, the output shaft of straight-line motion mechanism 3
31 is rapidly moving downward, and the first conveying roller 5 and the second conveying roller 5 ' clamp the downstream equipment transport of strip material 6.?
First conveying roller 5 and the second conveying roller 5 ' clamp the moment of strip material 6, since connecting rod endogenetic process makes the first compression
Spring 71 and the second holddown spring 72 deform in the horizontal direction, while the second hinge joint C is moved with sliding block 73.The
The deformation of one holddown spring 71 and the second holddown spring 72 reduces the impact force of pinch roller closure, when roll gap is opened, first
The connecting rod directed force that holddown spring 71 and the second holddown spring 72 are subject to disappears, and the second hinge joint C is restored to initially with sliding block 73
Position.
By comparison it is found that the number of drives and degree of freedom in system quantity of mesh first three clamping device are 1, and close
Section, connecting rod are all rigid connections, belong to the full driving mechanism of standard, and the movement of each joint and connecting rod has uniqueness, clamping
Rigid shock is generated to material when mechanism executes holding action, while not having pooling feature with the moment of material contact.And this
A kind of drive lacking link-type pinch mechanism provided is provided, the structure type of existing pinch roller single-degree-of-freedom is improved, mechanism
Number of drives is 1, and degree of freedom in system quantity is 2.Pinch mechanism can be in unactuated joint when completing synchronous holding action
Place is subjected to displacement, and is buffered by linear springs component to moment clamping force, is not only avoided because clamping impact force mistake
Aid object is damaged greatly, and clamped workpiece and clamping device itself components are all played a certain protective role, effectively
Extend the service life of equipment.
The above is the preferred embodiment of the application, is not limited the scope of protection of the present invention with this, it is noted that right
For those skilled in the art, under the premise of not departing from this technology principle, can also make it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the application.
