Abstract

The invention provides a turntable structure for turning and milling, which comprises a turntable base (1), a zero point positioning system (2), a workbench (3), a bearing (4), a central shaft (5), a water jacket (6), a fixed Shaft (7), wear ring (8), connecting plate (9), pneumatic clamp (10), torque motor (11). The present invention cooperates with the zero point positioning system (2) to realize the automatic loading and unloading of workpieces, and can take away the heat generated by the rotational friction between the fixed shaft (7) and the central shaft (5), so as to solve the problem of thermal deformation of the workbench (3) The problem is that the repeated positioning accuracy can reach 0.005mm, which improves the processing accuracy and processing efficiency of the workpiece.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a turning-milling compound turntable structure, especially a turning-milling compound turntable structure with loading and unloading functions. Background technique [0002] The structural part of the aerospace tube section is a typical product with many varieties, complex structure and various process categories. Most of the existing processing equipment are ordinary lathes, ordinary milling machines, bench drills and ordinary grinding machines, as well as a small number of CNC machining centers. The equipment functions single. For special-shaped barrel parts, it is necessary to use special fixtures to be clamped multiple times on multiple machine tools to complete the machining of the shape and surface in each direction, which cannot meet the requirements of the new generation of aerospace products in terms of machining accuracy, machining efficiency and...
