Abstract

The invention discloses an effective high-precision double-rotating working table of a vertical machining center. The effective high-precision double-rotating working table of the vertical machining center comprises a rotating table part, a right cradle part and a left cradle part, the rotating table part is arranged between the right cradle part and the left cradle part, one end of the left cradle part is firmly connected with the rotating table part, one end of the right cradle part is firmly connected with the rotating table part, and a rotating servo motor is arranged in the right cradle part. The effective high-precision double-rotating working table of the vertical machining center is simple and compact in structure and capable of realizing five-axis linkage and finishing complex curved surface processing after being fixed on a numerical control vertical machine tool, the right cradle part is driven by a rolling worm, the clearance can be adjusted through a left eccentric sleeve and a right eccentric sleeve so as to provide a large torque and a high rotating speed, the rotating table part uses a torque motor to directly drive the working table, the reverse clearance is eliminated, the locating precision is higher, and the rotating speed is high; a first cross roller bearing is capable of simultaneously bearing radial force and axial force, and the precision of the working table is reinforced.

Description

technical field [0001] The invention relates to the field of machine tool manufacturing, in particular to a double-rotary workbench of a high-efficiency and high-precision vertical machining center. Background technique [0002] Five-axis machine tools can be used to process many key parts with complex and special shapes, and have become the key basic equipment for the rapid development of equipment manufacturing and advanced defense weaponry products. The double turntable is an important structural form to realize five-axis. The machine tool is designed in the form of double swing tables, which can make more effective use of machine space and increase the processing range. The main shaft is fixed, and the length of the tool will not affect the swing error, and its rigidity can be increased at the same time. The existing rotary table has low speed, low positioning accuracy, and complex structure, so it is difficult to process complex workpieces with high efficiency and high ...
