Abstract

The invention relates to a compound vibration drilling device which is applied to various drilling machines and the drilling procedure of a processing center. The compound vibration drilling device mainly consists of three parts, namely a machine body, an ultrasonic torsion vibration system and a low-frequency axial vibration system, wherein the machine body plays a role of connecting and fixing the other two parts on the basis of the original processing function. The compound vibration drilling device realizes required ultrasonic torsion vibration by enabling the ultrasonic torsion vibration system to drive a drilling bit; the low-frequency axial vibration system drives a workpiece to realize low-frequency axial vibration; proper rotating speed and feeding amount can be selected by a drilling parameter setting system of the machine to perform compound vibration drilling processing. The compound vibration drilling device has the characteristics of high structural generality, high material applicability and the like, can develop respective advantages of different vibration drilling methods in ultrasonic, low frequency, torsion and axial direction, and is favorable for improving the drilling quality and realizing high-precision inner-hole drilling.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to an ultrasonic torsional and low-frequency axial compound vibration drilling device. Background technique [0002] Vibration drilling is a new type of drilling technology proposed by Professor Junichiro Kumabe of Utsunomiya University in Japan in the 1960s. Its essence is: on the basis of traditional drilling, regular and controllable vibration is applied to the tool or workpiece, and Through the optimal matching between vibration parameters and cutting parameters, the traditional drilling mechanism is changed, the process effect is improved, and high-efficiency precision inner hole processing is realized. After more than 50 years of development, vibration drilling has become a recognized advanced internal hole processing technology, and has unique advantages in drilling difficult-to-machine materials, deep and small hole drilling, and precision internal hole processing.
