Problems solved by technology

The steady frame used in the pipe processing lathe of the prior art when processing the tubular workpiece adopts the way of adding lubricating oil to keep the supporting claws in good contact with the workpiece, which not only increases additional operations, but is easily ignored, resulting in the The supporting claws are prone to wear and hinder the rotation of the workpiece, affecting the machining accuracy and reducing the machining efficiency
And only using three supporting claws to clamp the workpiece cannot keep the supporting claws and the workpiece in a stable fit, which may cause the workpiece to fall off during processing

Abstract

The invention discloses a center frame for processing strip-shaped workpieces, relates to the field of lathe accessory equipment, solves the problem that the existing center frame adopts the method of adding lubricating oil to maintain good contact between supporting claws and workpieces, and only uses three supporting claw clips Holding the workpiece, there is a problem that the support claw cannot be kept in a stable fit with the workpiece, causing the workpiece to fall off during processing. It includes a center frame body, on which a cavity with a hollow structure is set, and the center frame body also includes three pressing mechanisms and six adjustment mechanisms, and the three pressing mechanisms are evenly spaced around the cavity , three pressing mechanisms and six adjusting mechanisms extending to one end of the hollow structure inside the cavity are provided with blind holes, balls or pulleys are arranged in the blind holes, and the other ends of the three pressing mechanisms and six adjusting mechanisms One end is provided with threads and is connected with the cavity part through threads. The invention has the advantages of simple structure, stable contact between the supporting claw and the workpiece, and small friction, and is suitable for turning the elongated shaft.

Description

technical field [0001] The invention relates to the technical field of lathe accessory equipment, and more specifically relates to a center frame for processing strip-shaped workpieces. Background technique [0002] The center frame refers to the auxiliary device used to radially support the rotating workpiece during the machining process, and there is no relative axial movement with the workpiece during processing. The center frame is directly supported in the middle of the workpiece. When the workpiece can be turned in sections, the center frame is supported in the middle of the workpiece. In this way, the L / d value is reduced by half, and the rigidity of the slender shaft can be increased several times. Before the workpiece is mounted on the center frame, a groove supporting the center frame supporting claw must be turned in the middle of the blank. The surface roughness and cylindricity error should be small, otherwise the accuracy of the workpiece will be affected. Whe...
