Involute helical gear process and fixture design
【Abstract】The main content of this design is to design and study the processing route of the involute helical gear, including the processing methods of each process and selecting the appropriate tool, machine tool, fixture, selecting the reference plane, positioning and clamping scheme, One of the process design special fixtures. The end face, the tooth face and the inner hole are the main machining surfaces of the helical gear, and are designed according to the principle of the front face and the rear hole. Special fixtures are selected for the fixtures, and the clamping rigidity is high,which is suitable for mass production. The main content of this design is how to simplify the processing process and reduce the processing difficulty, thus achieving the purpose of improving the processing efficiency of the product.
