Abstract

The invention provides a machine tool for grinding a composite workpiece under the tensioning state. The machine tool comprises a machine tool, a grinding device and a tailstock tensioning device, wherein the grinding device is arranged at one end of a carriage opposite to a knife rest in the machine tool and is connected with a feeding mechanism on the carriage; and the tailstock tensioning device is arranged on the rear of a machine tool body. The machine tool can finish turning and grinding axial workpieces, and can effectively reduce radial runout, circular degree and other form and position tolerances of the workpiece and improve the machining accuracy by adopting a clamping mode under the tensioning state.

Description

technical field [0001] The invention relates to a grinding compound machine tool for turning the surface of shaft and pipe workpieces, which belongs to the technical field of mechanical processing equipment. Background technique [0002] The surface processing equipment for shaft workpieces usually includes lathes and grinders, etc. These equipments can only perform one function. Between transfers, the workpiece has to go through multiple clamping. In this way, not only the production efficiency is low, but also the clamping positioning datum will change after each clamping, especially for some slender shafts and thin-walled tube parts during the processing process, if the datum is changed in the second clamping Change, the processing of the next process will destroy the state after the processing of the previous process, and the processing positioning reference of the workpiece will change, making it difficult for the processed parts to meet the design requirements.
