Abstract

The invention discloses a numerical control and reducing ultrasonic vibration device for machining a complicated inner cavity of a deep hole. The device comprises a driving subassembly, a sliding subassembly, a knife sheath, a reducing boring rod subassembly and an ultrasonic transduction subassembly, wherein the ultrasonic transduction subassembly is mounted in the knife sheath and the knife sheath is mounted on a knife tower; a sliding block of the sliding subassembly is mounted on a base of the driving subassembly and a guide rail of the sliding subassembly is mounted on a box of a machinetool; and the reducing boring rod subassembly is connected with the sliding subassembly. According to the numerical control and reducing ultrasonic vibration device provided by the invention, the machining efficiency and the machining precision of the complicated inner cavity of the deep hole are improved by utilizing a numerical control and reducing way. The application range of ultrasonic vibration boring is enlarged.

Description

technical field [0001] The invention relates to a processing tool in the field of numerically controlled machine tools, more particularly, to a numerically controlled variable-diameter ultrasonic vibration device for machining complex deep hole inner cavities. Background technique [0002] With the rapid development of my country's aviation industry and the country's strong support, there are a large number of parts that require precision and ultra-precision machining in the aviation industry. Moreover, the residual stress on the processed surface is required to be small so that the parts can maintain accuracy for a long time. The engine is the heart of the aircraft, and the processing of its key components has become a bottleneck in the development of my country's aviation industry and a technical problem that we need to solve urgently. The boring bar used for machining has poor rigidity, large static clearance, poor wall thickness difference, severe dynamic chatter, and unf...
