Abstract

The invention relates to a deep hole machining device, in particular to an ultrasonic vibration assisted deep hole machining device. The ultrasonic vibration assisted deep hole machining device solves the technical problems that a tool is abraded severely, the surface quality is poor, and an oil supply device supplies oil inconveniently during the existing deep hole machining. The ultrasonic vibration assisted deep hole machining device comprises a drilling rod internally provided with a hollow structure, a connecting handle internally provided with a cavity, and an integrated amplitude transformer internally provided with a transducer, wherein one end of the connecting handle is opened; a cavity penetrating front and back is arranged in the center of the integrated amplitude transformer; the middle rear part of the integrated amplitude transformer is located in the cavity of the connecting handle and fixedly connected with the connecting handle; the front end of the integrated amplitude transformer is fixedly connected with the rear end of the drilling rod; and the cavity of the drilling rod is communicated with the cavity of the integrated amplitude transformer. The device applies ultrasonic vibration machining into deep hole machining of a gun drill, can effectively reduce a cutting force and cutting temperature and prolong the service life of the tool, reduces the surface roughness, and improves the machining precision.

Description

technical field [0001] The invention relates to a deep hole processing device, in particular to an ultrasonic vibration assisted deep hole processing device. Background technique [0002] In deep holes (hole depth L with aperture d 0 The ratio is greater than 5, that is L / d 0 >5) Among processing tools, gun drilling is used more and more as the main means of precision deep hole processing. However, with the increasing application of difficult-to-machine materials, such as difficult-to-machine metal materials, non-metal materials, composite materials, etc., severe tool wear, poor surface quality, low processing efficiency or even inability to process are prone to occur during drilling. In order to describe clearly, the cutting edge portion of the drill rod is called the front end, and the tail of the drill rod is called the rear end. Contents of the invention [0003] The present invention provides an ultrasonic vibration assisted deep hole processing device to ...
