Centrifugal center frame for machining long-axis workpiece

Abstract

The invention relates to the technical field of shaft machining equipment, and discloses a centrifugal center frame for machining a long-axis workpiece. The centrifugal center frame comprises a base, and a supporting ring frame is fixedly mounted at the top end of the base; the outer surface of the supporting ring frame is movably sleeved with a movable ring frame, and an outer casing is fixedly mounted on the front side of the movable ring frame; and a set of fan-shaped grooves are formed in the positions, corresponding to an inner cavity of the outer casing, of the movable ring frame, and inner cavities of the fan-shaped grooves are movably connected with movable pressing plates. According to the centrifugal center frame for machining the long-axis workpiece, through arrangement of internal structures of the fan-shaped grooves, the movable ring frame on the center frame can be rotated counterclockwise or clockwise to drive adjusting balls in the fan-shaped grooves in the movable ring frame to extrude a movable pressing plate towards one side of the movable ring frame under the action of centrifugal force; and therefore, the application range of the center frame is effectively expanded, and the stability and reliability of the center frame in the using process are effectively improved.

Description

Technical field[0001]The present invention relates to the technical field of shaft processing equipment, in particular a centrifugal center frame for long-axis workpiece processing.Background technique[0002]The central frame is an indispensable processing equipment that is an indispensable mechanical machine machining long shaft part. When the machining elongated shaft part is supported, the central standing is supported by the middle of the elongated shaft part to resist the elongated axis. The deflection of the middle of the medium is fixed.[0003]At present, the existing central frame needs to be used to find a job before use, and the Zhenggong homework is completed through artificial operation, which in turn takes a lot of time to find a job, thereby increasing the part of the part. Processing steps and processing time, and humanity is poorly accurate, thereby causing the circular jam in the high-speed rotation, greatly reduces its processing accuracy of the shaft part. Poor stab...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a centrifugal center frame for processing long-shaft workpieces, which can effectively improve the machining accuracy of slender shaft parts and shorten the processing time of the center frame without man-made alignment operations. The advantages of high time, stability and reliability solve the problem that the existing center frame needs to be aligned before use, and the alignment is done manually, which takes a lot of time to complete. Alignment operations are carried out, which increases the processing procedures and processing time for such parts, and the accuracy of artificial alignment operations is poor, which leads to large circular runout errors of long-axis parts during high-speed rotation. Greatly reduce the problem of poor processing accuracy, stability and reliability
