Structure of the present utility model can be specially:
Clamping device also comprises the pressing plate adjusting device, and the pressing plate adjusting device is connected with pressing plate with actuating unit respectively.
Like this, regulate by the pressing plate adjusting device, it is coaxial making the axis of piston and machine tool chief axis, adds the error that produce man-hour thereby reduce, and guarantees machining accuracy.
The structure of pressing plate adjusting device can have two kinds of selections:
First kind
Pressing plate adjusting device or comprise that two are regulated bolts, two adjusting nuts and bolting plate, the two ends of bolting plate have a through hole respectively, the through hole that the adjusting bolt passes on the bolting plate is connected with pressing plate, adjusting nut is installed in to be regulated on the bolt between pressing plate and bolting plate, and the bolting plate is connected with actuating unit.
Like this, the through hole that the adjusting bolt is passed bolting plate two ends is connected with pressing plate, and adjusting nut is screwed between the pressing plate of regulating on the bolt and bolting plate, and the bolting plate is connected with actuating unit.Behind the actuating unit hold-down bolt fixed head, the bolting plate just is pressed on the adjusting nut, and adjusting nut makes the adjusting bolt that pressing plate is pressed on the piston end surface again, thereby piston is clamped.When clamped piston axis and machine tool chief axis were not parallel, the adjusting nut of regulating bolting plate both sides just can be adjusted the direction of piston axis, makes piston axis parallel with machine tool chief axis.
Second kind
Pressing plate adjusting device or comprise two differential heads and differential head fixed head, the two ends of differential head fixed head have a through hole respectively, and the differential head passes this through hole and is connected with pressing plate, and differential head fixed head is connected with actuating unit.
Like this, regulate by the differential head, degree of regulation is higher.
In addition, the pressing plate adjusting device also comprises two connecting bolts, and two connecting bolts lay respectively at the both sides of differential head fixed head, and it runs through differential head fixed head and is connected with pressing plate, be with the compression spring on the connecting bolt, this compression spring is between the bolt head and differential head fixed head of connecting bolt.
Like this, the compression spring just is pressed on differential head fixed head on the differential head all the time, and it is more accurate that the differential head is regulated.
Structure of the present utility model can further be specially:
Also comprise sliding track mechanism, when clamping device comprised a kind of pressing plate, pressing plate was fixed on the sliding track mechanism; When clamping device also comprised the pressing plate adjusting device, the pressing plate adjusting device was fixed on the sliding track mechanism.
Like this, when moving by actuating unit promotion pressing plate or pressing plate adjusting device, pressing plate or pressing plate adjusting device can move on slide rail.
Actuating unit of the present utility model or be a kind of hydraulic cylinder perhaps is a kind of cylinder, and its output shaft is connected with hold down gag.
In sum, the utility model has the following advantages compared to existing technology: piston crown mills and adds man-hour, clamps by the pin-and-hole location of piston and from piston end face, and piston is not yielding, and the form error of piston reduces, and machining accuracy improves.
