Background technology
When processing part, some parts need to process part, previous numerically-controlled machine tool with hole high accuracy positioning numerically-controlled machine tool
When processing part needs are positioned with hole, generally first presses hole and prepare a locating shaft, then on the table by locating shaft fixation, due to
The part location hole aperture processed every time is different, is required for preparing locating shaft every time, seriously affects the clamping zero of numerically-controlled machine tool
Part efficiency, waste material, the raising for restricting production efficiency.
Invention content
In view of the problems of the existing technology, the present invention provide it is a kind of for CNC milling machine processing in hole be position it is fast
Speed automatic positioning binding clasp, the positioning clamping apparatus can realize that part needs the demand processed with hole high accuracy positioning, repeat
Using, convenient for 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 automatic positioning binding clasp include workpiece 1, pressing plate 2, pin 3, spring 4, push rod 5, mandril 6, axis pin 7,
Release link 8, screw 9, cylinder 10, pedestal 11.
The pedestal 11 is step square shaft, and 11 top of pedestal is rectangular；The 11 middle part vertical direction of pedestal has one
The through-hole of perforation, for placing mandril 6；Two pressing plates 2 are fixedly mounted by axis pin 7 in 11 both sides of pedestal；The bottom
Place release link 8 in 11 lower parts of seat；Cylinder 10 is fixedly mounted by screw 9 in 11 lower surface of pedestal.
10 top of cylinder is connect with mandril 6；One circle symmetrically recessed area inwardly is arranged at the top of the mandril 6
Domain, surface are circular arc type, and 6 top circular arc type region of mandril and the side of push rod 5 connect, the other side of push rod 5 and pressure
2 overlying contact of plate；The lower part of the mandril 6 is part-conical type, and 6 lower part of mandril and the side of release link 8 connect, multiple
The other side of position bar 8 and 2 lower contact of pressing plate.The push rod 5 is horizontally fixed on by pin 3 on pedestal 11, and 5 middle part of push rod is opened
There is notch, spring 4 is installed in notch, pine automatically resets when pressing from both sides, and is convenient for clamping workpiece.
Cylinder 10, which is withdrawn, when work drives mandril 6 to withdraw, and mandril 6 drives the movement of push rod 5, push rod 5 that two pressing plates 2 is pushed to move
It is dynamic, make 2 outside 1 hole wall of tensioner workpiece of pressing plate；Cylinder 10 drives mandril 6 protruding when pine folder, effect of the push rod 5 in spring 4
Lower withdrawal, 2 lower parts that release link 8 withstands pressing plate make pressing plate 2 open.
Beneficial effects of the present invention are：The present invention uses the localization method of two pressing plate locating tensioning hole walls, positioning rapid
Reliably, positioning accuracy is high；Spring is installed, pine can automatically reset when pressing from both sides, and be convenient for clamping workpiece in jogger hole；Cylinder is installed to be convenient for certainly
Dynamic control.Manufacturing cost of the present invention is low, versatile, can Reusability, positioning, clamp it is primary complete, greatly improve numerical control mill
The production efficiency of bed clamping.
