Abstract
The utility model is related to machine industries, specially a kind of centering hold-fast body, specifically include spring, swing rod one, swing rod two, axis pin, idler wheel one, idler wheel two, push shaft, guide sleeve, swing rod one, swing rod two are connected by axis pin, on guide sleeve, for spring between swing rod one, swing rod two, idler wheel one, idler wheel two are separately mounted to swing rod one, one end of swing rod two, and push shaft is mounted in guide sleeve and is contacted with idler wheel one, idler wheel two.The advantages of the utility model, is as follows：Push shaft moves down, and wedge surface is contacted with idler wheel, and workpiece is held in the centering of swing rod stress tightly, and the mechanism structure is compact, effect is apparent, and the centering that can adapt to small-bore or large aperture simultaneously is held tightly.
Description
Technical field
The present invention relates to machine industries, are specially a kind of centering hold-fast body.
Background technology
At present, to the centering body of round hole mainly using tensioner mode, which can only one hole of centering, if
It needs while two holes of centering, which cannot be met the requirements.
The content of the invention
The object of the present invention is to provide a kind of centering hold-fast bodies, when too small to middle aperture, the arrangement of single hole tension mechanism
Under not or when aperture is excessive, single hole tension mechanism can it is excessively huge in the case of, can solve to appeal with holes centering hold-fast body
Problem.
The present invention technical solution be：A kind of centering hold-fast body specifically includes spring, swing rod one, swing rod two, pin
Axis, idler wheel one, idler wheel two, push shaft, guide sleeve, swing rod one, swing rod two are connected by axis pin, and on guide sleeve, spring exists
Between swing rod one, swing rod two, idler wheel one, idler wheel two are separately mounted to swing rod one, one end of swing rod two, and push shaft is mounted on guide sleeve
It is interior to be contacted with idler wheel one, idler wheel two.
Advantages of the present invention is as follows：Push shaft moves down, and wedge surface is contacted with idler wheel, and workpiece, the machine are held in the centering of swing rod stress tightly
Structure is compact-sized, effect is apparent, and the centering that can adapt to small-bore or large aperture simultaneously is held tightly.
Description of the drawings
Fig. 1 is the working state schematic representation of the present invention.
Fig. 2 is the relaxation state schematic diagram of the present invention.
Specific embodiment
As shown in Figure 1, a kind of centering hold-fast body, specifically includes：Spring 1, swing rod 1, swing rod 23, axis pin 4, idler wheel
One 5, idler wheel 26, push shaft 7, guide sleeve 8, which is characterized in that swing rod 1, swing rod 23 are connected by axis pin 4, mounted on guiding
On set 8, for spring 1 between swing rod 1, swing rod 23, idler wheel 1, idler wheel 26 are separately mounted to swing rod 1, the one of swing rod 23
End, push shaft 7 are mounted in guide sleeve 8 and are contacted with idler wheel 1, idler wheel 26.
Concrete operating principle：Push shaft 7 moves down, 7 wedge surface of push shaft and swing rod 1, the idler wheel 1 on swing rod 23, idler wheel two
Workpiece is held in 6 contacts, swing rod 1,23 stress centering of swing rod tightly, and push shaft 7 moves up, 7 wedge surface of push shaft and swing rod 1, swing rod 23
On idler wheel 1,26 points of idler wheel open, swing rod 1, swing rod 23 strut under the action of spring 1 leaves workpiece.
