Description

Technical Field

[0001] The invention belongs to the technical field of drilling processing devices for electromechanical products, and in particular relates to an ultrasonic vibration drilling device for processing mechanical electromechanical products. Background Art

[0002] Ultrasonic drilling is a common processing method in the drilling process of electromechanical products. From the perspective of product structure, ultrasonic drilling is mainly composed of an ultrasonic generator, a transducer, a horn, a tool head, etc. Among them, the ultrasonic generator is responsible for generating high-frequency electrical signals to drive the transducer to generate mechanical vibrations; the transducer converts the electrical signal into mechanical vibrations and amplifies the amplitude through the horn; finally, the tool head transmits the vibrations to the workpiece to achieve drilling. From the perspective of the working principle of the product, the ultrasonic drilling machine uses the energy of ultrasound to drill holes. When ultrasound acts on the workpiece through the tool head, high-frequency vibrations and tiny cracks are generated, and finally drilling is achieved. This drilling method is not only fast and precise, but also does not damage the workpiece. It is suitable for hole processing of various materials and various sizes.

[0003] However, during the ultrasonic drilling of existing electromechanical products, the amplitude transformer of the ultra-deep drilling gun lacks a stable support structure, which easily causes circumferential shaking during the drilling process, causing the hole diameter to expand.
