Abstract

The invention discloses a mandrel supporting device for a cylindrical workpiece. The mandrel supporting device comprises a mandrel, a split lining body and a plurality of length adjusting rods, wherein the split lining body is clamped on the mandrel, and the plurality of length adjusting rods are uniformly distributed in the circumferential direction of the outer edge of the split lining body; andthe length adjusting rods comprise tubular parts, shaft sleeves, transition joints, supporting rods, ejector rods and top block assemblies, wherein the tubular parts are fixedly connected with the split lining body, the shaft sleeves are arranged in the tubular parts, threads are arranged at the two ends of each transition joint, one ends of the transition joints are in threaded connection with the shaft sleeves, the other ends of the transition joints are in threaded connection with one ends of the supporting rods, the shaft sleeves and the supporting rods are opposite to the rotating direction of threaded holes which are connected with the transition joints, the other ends of the supporting rods are in threaded connection with one ends of the ejector rods, the other ends of the ejectorrods are connected with the top block assemblies, and the top block assemblies are used for abutting against the inner wall of the cylindrical workpiece to be machined. The mandrel supporting device for the cylindrical workpiece is suitable for large-size cylindrical workpieces, and adaptability of the mandrel supporting device is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a mandrel supporting device for a cylindrical workpiece. Background technique [0002] In the field of mechanical processing technology, cylindrical workpieces such as turning drums, reels and shield shells are usually supported by mandrel clamping, and mandrel clamping is usually achieved by supporting the inner wall of the cylindrical workpiece. The purpose of the cylindrical workpiece is to enable the tool to process the outer wall of the cylindrical workpiece without the obstruction of the clamping tool, and to reduce the difficulty of lathe processing the cylindrical workpiece. At present, several common mandrel forms include: cylindrical mandrel, tapered mandrel and expansion force mandrel, etc. Among them, the cylindrical mandrel is suitable for the case where the length of the cylindrical workpiece is smaller than the diameter of the hole, the tapered mandr...
