Abstract

The invention discloses a large-scale high-precision numerical control tooth disc grinding machine. The large-scale high-precision numerical control tooth disc grinding machine comprises a machine tool bed. A rotary workbench capable of moving horizontally is arranged on the machine tool bed. A stand column perpendicular to the machine tool bed is mounted on one side of the machine tool bed. A movable machining mechanism is arranged on the stand column. First linear guide rails are arranged on the surface of the machine tool bed. A base of the rotary workbench is clamped into the first linear guide rails. The machining mechanism comprises a sliding seat. A grinding tool base capable of moving horizontally is arranged on the sliding seat. A grinding tool mechanism is mounted on the grinding tool base. A second linear guide rail perpendicular to the machine tool bed is arranged on the surface of the stand column. The sliding seat is clamped to the second linear guide rail. A third linear guide rail is arranged on the sliding seat. A grinding tool is clamped to the third linear guide rail through the grinding tool base. By the adoption of torque motor direct-drive indexing and workbench positioning, the workbench top indexing accuracy is improved; and a traditional hobbing machine structure layout is adopted for the tooth disc grinding machine, the stand column is fixed, and the rigidity of a grinding tool system is improved.

Description

technical field [0001] The invention relates to the field of equipment manufacturing precision processing equipment and transmission technology, in particular to a large-scale high-precision numerically controlled tooth disc grinding machine. Background technique [0002] With the development of China's equipment manufacturing industry, there are further requirements for the processing of materials, which require high-precision and precise processing devices for processing. Therefore, in order to expand and extend functional components to large, high-rigidity, and high-precision, therefore, Various high-precision intermittent circumferential indexing devices, multi-position positioning mechanisms and other equipment manufacturing industries need high-precision toothed discs. [0003] At present, the horizontal shaft moment flat grinding structure is often used to process straight toothed discs, and the machine tool structure with an indexing turntable is added. When process...
