Abstract

The invention discloses a compound vibration drilling device and a machining method. The compound vibration drilling device comprises machine tool spindle motor and a drill bit and is characterized by further comprising a vibration tool handle and a vibration control system. The vibration control system comprises a monitoring system and an executing system. The executing system comprises a low-frequency vibration generator, an ultrasonic vibration generator, a stepping motor, a servo drive motor and an electric brush. The vibration controller controls the low-frequency vibration generator through the servo drive motor and the stepping motor. The vibration controller controls the ultrasonic vibration generator through the electric brush. By means of the machining method, on the basis of traditional laminated component drilling machining, the compound ultrasound or low-frequency axial vibration is adopted according to material attribute differences of different materials, conversion of vibration drilling and common drilling, conversion of ultrasonic vibration drilling and low-frequency vibration drilling and adjusting of vibration parameters in the machining process can be achieved through the vibration controller, and high-quality manufactured holes are obtained.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, in particular to a compound vibration drilling device and a processing method. Background technique [0002] With the development of economy and the improvement of science and technology, difficult-to-process materials have been widely used in all walks of life. Difficult-to-machine materials are mainly divided into: high-strength and tough-type difficult-to-machine materials, such as titanium alloys, superalloys, etc.; high-hardness and brittle materials, such as ceramics, silicon wafers, etc.; and various composite materials with both high strength and toughness and high hardness and brittleness Material. [0003] As an auxiliary machining method, vibration machining has been widely used since it was proposed in the 1960s. Vibration-assisted hole making technology is an important branch of vibration machining. The difference between it and ordinary drilling lies in the controlla...
