There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
The embodiment of invention for those of ordinary skill in the art without creative efforts, can also basis
The attached drawing of offer obtains other attached drawings.
Fig. 1 be fixture provided in an embodiment of the present invention be receive chuck tool when decomposition diagram；
Fig. 2 be fixture provided in an embodiment of the present invention be receive chuck tool when structural schematic diagram；
The structural schematic diagram that Fig. 3 is fixture provided in an embodiment of the present invention when being outer support formula fixture.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figs. 1-3, fixture provided in an embodiment of the present invention includes：Stationary jaw 9 is used cooperatively with stationary jaw 9
Movable jaw, and driving movable jaw movement driving device.
It is understood that driving device driving movable jaw moves back and forth, to realize that movable jaw is matched with stationary jaw 9
Realization is closed to clamp and release.
Claw is divided into stationary jaw 9 and movable jaw by fixture provided in an embodiment of the present invention, and driving device only drives work
Dynamic claw movement is to realize clamping and releasing for fixture, in this way so that the clamping face of stationary jaw 9 is used as reference plane, only movable
Claw moves, and compared with the prior art, reduces influence of the product size tolerance to fixture, improves the reliability of fixture, drops
Low influence of the fixture to product processing quality.
For the number and shape of stationary jaw 9 and movable jaw, according to waiting for that folder is designed.Preferably, above-mentioned work
Dynamic claw is two, and has angle between the clamping face of two movable jaws.
Specifically, two movable jaws are respectively the first movable jaw 16 and the second movable jaw 17.Two movable jaws
Clamping face between angle be more than zero degree and be less than 180 degree.It is understood that two movable jaws are adjacent.Certainly, also may be used
Select movable jaw for three or more, it is not limited to above-described embodiment.
In order to ensure clamping effect, two movable jaws of above-mentioned driving device driving move synchronously and two movable jaw energy
Enough compensation wait for the size difference of folder.It is understood that two movable jaw linkage settings so that two movable jaws can
Compensation waits for that the size difference of folder waits for folder to clamp.
It should be noted that the reason of because of machining accuracy, size and the standard size of product have differences, and size difference is
Refer to the standard-sized difference of the actual size and product of product；Compensation waits for the size difference of folder, refers to a movable jaw
Movement pre-determined distance can compensate for the size difference of a size of product so that another movable jaw also moves pre-determined distance
With the size difference of another size of compensation product.Specifically, a movable jaw movement pre-determined distance can compensate for product
Length dimension size difference so that another movable jaw also moves pre-determined distance with the ruler of the width dimensions of compensation product
Very little difference.
Above-mentioned fixture, size difference can be mutually compensated for by realizing two movable jaws, then further reduced product ruler
The very little influence to fixture further improves the reliability of fixture.
For the ease of driving movable jaw movement, above-mentioned driving device includes：Driving part 3, and erecting driving part 3
Straight driving direction is converted to the driving mechanism in horizontal drive direction；Wherein, driving mechanism is connected with movable jaw.
Further, above-mentioned driving mechanism includes：Two sliding parts, cross-member and longitudinal connecting member 11；Wherein, movable
Claw is fixed on sliding part；Cross-member drives sliding part movement so that fixture can clamp and release；Longitudinal connecting member 11 by
Driving part 3 drives and cross-member is driven to move in the horizontal direction.
It is understood that sliding part is corresponded with movable jaw, two sliding parts are respectively 14 He of the first sliding part
Second sliding part 15.
Above-mentioned cross-member includes：Laterally movable part 13 and the transverse connection 6 being connected with laterally movable part 13, two
Sliding part is connected with the both ends of transverse connection 6 respectively, and laterally movable part 13 is connected with longitudinal connecting member 11, cross-member and cunning
Moving part moves in the horizontal plane.
In above-mentioned fixture, drive longitudinal connecting member 11 vertically moving by driving part 3, so that cross-member edge
Horizontal motion, to drive sliding part to move in the horizontal plane so that the movable jaw movement being fixed on sliding part, into
And it realizes that movable jaw is matched for clamping tightly with stationary jaw 9 and waits for that folder and movable jaw discharge far from the realization of stationary jaw 9 and wait pressing from both sides
Part.
Above-mentioned driving structure can also be other structures, it is not limited to above-described embodiment.
For the ease of realizing that the transmission of movement, above-mentioned longitudinal connecting member 11 are equipped with the first driving structure 12, laterally movable part
13 are equipped with the first connector that can be moved along the first driving structure 12；Sliding part is equipped with the second driving structure 7, transverse connection
6 are equipped with the second connector that can be moved along the second driving structure 7.
For the ease of processing and selection, above-mentioned first driving structure 12 is the first drive hole, and the second driving structure 7 is second
Drive hole；First drive hole and the second drive hole are strip-shaped hole；First connector and the equal pin of the second connector 18.
