Embodiment Construction

[0025] like figure 1 and figure 2 As shown, the present invention creates a modularized B-axis turning-milling compound functional unit consisting of a turning-milling head module 1 and a B-axis module 2 . Turning and milling head module 1 can be installed with turning tools, milling cutters, drills and other processing tools. B-axis module 2 can swing along the B-axis driven by the motor. Turning and milling head module 1 is connected to the flange of B-axis module 2 through bolts 3 on shaft 214.

[0026] The B-axis module 2 mainly includes: a motor drive device, a three-ring indexing structure and a brake structure. Its motor drive device such as figure 2 As shown, the motor stator 212 of the B-axis module 2 is fixed on the rear cover 215 of the B-axis module 2 by screws, the motor stator 212 and the rear cover 215 are installed together in the box body 211, and the rear cover 215 is fixed on the box body by screws 211 on. The motor rotor 213 is fixed on the shaft 216...

Abstract

The invention relates to a turning and milling composite functional unit for a numerical control machine, in particular to a modularized B-axis turning and milling composite functional unit, which comprises a B-axis module and a turning and milling head module, wherein the B-axis module comprises a driving device, a three-fluted-disc indexing structure and a brake structure, the turning and milling head module comprises a motor driving device and a three-fluted-disc fixing device, the turning and milling head module id driven by a built-in motor, and is provided with a three-fluted-disc locking structure, during turning, three fluted discs are locked to ensure structure rigidity, during milling or drilling, the three fluted discs are loosened, and a main shaft rotates to drive a cutter to carry out processing. The B-axis module is driven by the built-in motor, during indexing processing, the three-fluted-disc locking structure is adopted to ensure the structure rigidity and the indexing accuracy; and during processing at any angle, the brake mechanism is adopted to ensure the processing rigidity. The B-axis module and the turning and milling head module are connected through screws, and according to processing requirements, different turning and milling heads are replaced so as to expand processing capability.

Description

technical field [0001] The invention relates to a turning-milling compound functional unit for a numerical control machine tool, specifically a modularized B-axis turning-milling compound functional unit. Background technique [0002] The development of industry has put forward higher requirements on the processing performance of machine tools. For complex curved surface parts in aviation, aerospace, military and other industrial fields, it is difficult to achieve high-efficiency and high-precision processing by using traditional processing methods such as turning and milling, and two-axis and three-axis linkage processing methods. With a variety of static and rotating tools, it can process a variety of complex shape workpieces under one clamping. The multi-axis turning-milling compound machining center with multi-axis linkage function and short standby time has become an important processing equipment in these fields. The turning-milling compound functional unit is an impo...
