Abstract

The invention discloses an ultrasonic drilling device. The device is mainly composed of a sleeve cup, an induction coil set, a cooling system, a transducer, an amplitude transformer and a drill pipe,the top of the sleeve cup is connected with a machine tool main shaft through a clamping mechanism, and the lower portion of the sleeve cup is open. The induction coil set matched with the transduceris wound on the outer wall of the sleeve cup; the cooling system and the transducer are arranged in the open end of the sleeve cup; the driving end of the transducer is connected with the input end ofthe amplitude transformer, the amplitude transformer is fixed to the end face of the open end of the sleeve cup through a connecting bolt, and the output end of the amplitude transformer is connectedwith the upper end of the drill pipe; and a cutter is arranged at the lower end of the drill pipe. The ultrasonic drilling device has the beneficial effects that the ultrasonic drilling device is connected with the machine tool main shaft through the clamping mechanism, rotation of the machine tool main shaft and longitudinal vibration of the transducer form longitudinal-torsion composite vibration, and then a workpiece can be drilled; the cooling system is integrated in the ultrasonic drilling device, the transducer and the workpiece can be simultaneously cooled, and an external cooling system is not needed; and the ultrasonic drilling device is high in machining speed, high in machining precision, good in machining quality and small in abrasion of the drill pipe.

Description

technical field [0001] The invention relates to the field of ultrasonic technology, in particular to an ultrasonic drilling device. Background technique [0002] Due to the large weight and volume, high energy consumption and high pressure of the drill bit, the traditional drilling device has conventional mechanical failure forms, which are far from being able to meet the processing of hard and brittle materials such as ceramics, carbon fiber and other composite materials. Ultrasonic drilling equipment has the advantages of simple structure, small size, light weight, low energy consumption, and small axial force, and is widely used. [0003] In the ultrasonic processing system, the horn and the tool are assembled together, and the shape and size of the horn are adjusted by design to achieve the purpose of mechanical resonance; but this method is complex in calculation and cannot automatically adjust the output frequency, and it will also Problems that affect processing such...
