Description
Technical field
The utility model relates to a kind of positioning chuck of numerically controlled lathe.
Background technology
Numerically controlled lathe adds man-hour carrying out longaxones parts, must use chuck, fix workpiece by chuck, and then drive shaft drives chuck to rotate, and chuck drives workpiece to do gyration, then carries out turning by cutter to workpiece.
But chuck of the prior art is mostly simple scroll chuck, its concentricity is poor, and therefore add man-hour carrying out longaxones parts, part is in turning process, and position can be biased, and the concentricity after causing part to be processed is poor, and surface is comparatively coarse.
So how improving the axiality that chuck fixes is the problem needing to be solved.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of positioning chuck of numerically controlled lathe, and this device can improve the fixed fastening force of part, reduces shaking force during its turning, improves the machining accuracy of part.
For solving the problem, the utility model adopts following technical scheme:
A kind of positioning chuck of numerically controlled lathe, comprise chuck body, the right-hand member of described chuck body is coaxially arranged with a clamping part protruded, described chuck body inside has locating hole, locating slot is provided with in described locating hole, described clamping part has a fixing hole, fixing hole and locating hole are coaxially arranged, positioning sleeve is combined with in described locating hole, the outer surface of described positioning sleeve is provided with the locating piece relative with described locating slot, the outer surface of described positioning sleeve is provided with plural shoulder hole, the first fixed screw is connected with at described shoulder hole internal thread, the inner surface of described fixing hole is provided with the tread plate that several protrude, on the outer surface of described clamping part, annular is provided with three fixed screws.
As preferred technical scheme, the right side of described chuck body offers a louvre communicated with described locating hole.
As preferred technical scheme, described chuck body and described clamping part joint place are provided with destressing groove.
As preferred technical scheme, the aperture of described fixing hole is greater than the aperture of described locating hole.
As preferred technical scheme, the angle between two adjacent described fixed screws is 120 °.
The beneficial effects of the utility model are: this device is provided with positioning sleeve, add man-hour carrying out part, can first by little for the end face car of part, then part is inserted in positioning sleeve, by positioning sleeve, part is fixed on chuck body inside again, then by fixed screw, part is carried out secondary again to fix, greatly can improve the fastening force to part, it is avoided to shake in process, improve the precision of part processing, the structure of this device is comparatively simple simultaneously, manufactures more for convenience, is applicable to promoting the use of.
