Background technology
When part is processed, some parts need to process part, conventional Digit Control Machine Tool with hole high accuracy positioning Digit Control Machine Tool
When processing part needs to be positioned with hole, a locating shaft first typically is prepared by hole, then by locating shaft fixation on the table, due to
The part location hole aperture of processing is different every time, is required for preparing locating shaft every time, has a strong impact on the clamping zero of Digit Control Machine Tool
Part efficiency, waste of materials, the raising of restriction production efficiency.
The content of the invention
For the problem that prior art is present, it is the fast of positioning with hole in being processed for CNC milling machine that the present invention is provided a kind of
Speed is automatically positioned binding clasp, and the positioning clamping apparatus can realize that part needs the demand processed with hole high accuracy positioning, repeat
Using, be easy to automatically control, reduce production cost, improve production efficiency.
In order to achieve the above object, the technical scheme is that：
A kind of internal expansion type be automatically positioned binding clasp including workpiece 1, pressing plate 2, pin 3, spring 4, push rod 5, push rod 6, bearing pin 7,
Release link 8, screw 9, cylinder 10, base 11.
Described base 11 is step square shaft, and the top of base 11 is square；The described middle part vertical direction of base 11 has one
The through hole of insertion, for placing push rod 6；The described both sides of base 11 fixedly mount two pressing plates 2 by bearing pin 7；Described bottom
Place release link 8 in 11 bottoms of seat；The described lower surface of base 11 fixedly mounts cylinder 10 by screw 9.
The described top of cylinder 10 is connected with push rod 6；The top of described push rod 6 has a circle symmetrical to the recessed area in inner side
Domain, its surface is circular arc type, and the top circular arc type region of push rod 6 is connected with a side contacts of push rod 5, opposite side and the pressure of push rod 5
The overlying contact of plate 2；The bottom of described push rod 6 is part-conical type, and the bottom of push rod 6 is connected with a side contacts of release link 8, multiple
The opposite side and the lower contact of pressing plate 2 of position bar 8.Described push rod 5 is horizontally fixed on base 11 by pin 3, and the middle part of push rod 5 is opened
Have and spring 4 is installed in notch, notch, automatically reset during pine folder, be easy to clamping workpiece.
Cylinder 10 withdraws and drives push rod 6 to withdraw during work, and push rod 6 drives push rod 5 to move, push rod 5 promotes two pressing plates 2 to move
It is dynamic, make the outside hole wall of tensioner workpiece 1 of pressing plate 2；Cylinder 10 drives push rod 6 protruding during pine folder, effect of the push rod 5 in spring 4
Lower withdrawal, 2 bottoms that release link 8 withstands pressing plate open pressing plate 2.
Beneficial effects of the present invention are：The present invention is using two localization methods of pressing plate locating tensioning hole wall, and positioning is rapid
Reliable, positioning precision is high；Spring is installed in jogger hole, can be automatically reset during pine folder, be easy to clamping workpiece；Cylinder is installed to be easy to certainly
Dynamic control.Low cost of manufacture of the present invention, highly versatile, can Reusability, positioning, clamp once complete, greatly improve numerical control mill
