Large-scale high-precision CNC tooth disc grinding machine

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...

AI Technical Summary

Problems solved by technology

When processing large-diameter parts, there will be problems of long overhang and weak rigidity of the main shaft, which will affect the contact accuracy and indexing accuracy of the parts. In addition, due to the limitation of technology and equipment, the diameter of the tooth disc that can be processed is very large. Limited, complex structure and high cost
