Lathe clamping device and box type part dispersed inner hole machining method

Abstract

The invention provides a lathe clamping device and a box type part dispersed inner hole machining method, and relates to the technical field of clamps. The lathe clamping device comprises a faceplate, a first mandrel, a second mandrel and an indexing taper sleeve. The first mandrel is arranged at the circle center of the faceplate and used for being connected with a main shaft of the machine tool, and therefore when the main shaft of the machine tool is in the running state, the main shaft drives the first mandrel to rotate, and a workpiece to be machined is driven to rotate around the first mandrel. The second mandrel is arranged on the faceplate and is spaced from the first mandrel; the indexing taper sleeve is rotatably arranged on the second mandrel in a sleeving mode and used for being arranged in a center hole of a workpiece to be machined, the machining precision can be improved, the adaptability and efficiency of the workpiece to be machined in the lathe machining process are improved, the clamping time is remarkably shortened, the clamping precision is improved, the labor intensity of operators is relieved, the overall production efficiency is improved, and the machining cost is reduced. And meanwhile, errors caused by multiple times of operation of operators are reduced, and standardization and consistency of machining are achieved.
