超声振动钻削装置设计与研究

Design and Research of an Ultrasonic Transducer Drilling Device

为解决碳纤维复合材料和钛合金钻孔加工过程中钻头磨损严重、加工孔质量差等问题,研制了一款超声振动钻削装置。超声振动钻削装置的性能取决于声振系统设计的好坏。本文首先对声振系统的结构设计进行了理论探讨,然后采用ANSYS软件对其进行了模态分析和谐响应分析。在碳纤维复合材料和钛合金的初步钻削试验中,超声振动钻孔和普通钻孔相比轴向钻削力分别减少了48%和31%,结果表明所研制的超声振动钻削装置具有良好的钻削性能。

In order to solve the problem of severe drill wear and bad quality of hole process of carbon fiber composite materials and titanium, an ultrasonic vibration drilling processing during the drilling device is designed. The per- formance of ultrasonic vibration drilling device depends on the quality of sound vibration system. In this paper, the design of the structure of the sound vibration system Was analyzed theoretically. And then the modal analysis and har- monious response analysis was carried out using the ANSYS software. In the drilling tests of the carbon fiber composite materials and titanium, the ultrasonic vibration drilling axial drilling force decline 48% and 31% than ordinary drill- ing axial drilling force respectively. It showed that the developed ultrasonic vibration drilling device has a good drilling performance.
