Machining method of transition sleeve and shaft suitable for shaft machining

Abstract

The invention discloses a transition sleeve applicable to shaft machining and a shaft machining method, and belongs to the field of machining. The transition sleeve comprises a cylindrical body and aplurality of tightening components; a plurality of through holes are formed in the cylindrical body; each tightening component comprises a mounting pipe, a rolling ball, a spring and a threaded ejection rod, so that the threaded ejection rods can be unscrewed before the transition sleeve is arranged on a thin and long shaft; the rolling balls are exposed outer of the through holes under the actionof the springs, so that the rolling balls can be in contact with the surface of a component when the transition sleeve is arranged; the springs achieve a certain supporting effect on the cylindricalbody, so that the cylindrical body can be prevented from being in direct contact with the component; the rolling balls can rotate when the cylindrical body moves in the axial direction of the component; after the cylindrical body is moved to a proper position, the rolling balls can be tightened to the surface of the component by screwing the threaded ejection rods; and the cylindrical body can becoaxial with the component by screwing a plurality of the threaded ejection rods, so that the machining of a thin and long shaft component is facilitated, and the problem that the component is scratched by the transition sleeve is avoided.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a transition sleeve and a shaft processing method suitable for shaft processing. Background technique [0002] Slender shaft parts refer to shaft parts whose length to diameter ratio is greater than 25. [0003] When processing slender shaft parts, because the workpiece is slender, the rigidity of the workpiece is poor and it is easy to vibrate. When it is subjected to cutting force, it will cause bending and vibration, and the processing is very difficult. Therefore, the center frame is usually used for support during turning. Increase the rigidity of the workpiece. [0004] When the slender shaft is supported by the center frame, a transition sleeve is usually coaxially sleeved on the shaft first, and then the transition sleeve is supported by the center frame. Because the diameter of the transition sleeve and the diameter of the slender shaft parts usually differ by only ...
