Linear pattern non-angular ultrasonic impact gun as shown in Figure 1 is made up of ultrasonic-frequency power supply (being supersonic generator) and executing agency's (being linear pattern non-angular ultrasonic impact gun) two parts.Adopt half digitlization and Digital Control supersonic generator, its effect is that industrial-frequency alternating current is converted to the supersonic frequency vibration, to supply with impact gun working head energy.
But when handling some baroque workpiece or comparatively special angle, existing linear pattern non-angular ultrasonic impact gun is limited to the restriction of own vol and version and can't implements shock treatment well or treatment effect is not good.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of easily and fast, low-cost, the bevel angle ultrasonic impacting gun that adapts to various locus and angle.
The technical solution adopted in the present invention is: a kind of bevel angle ultrasonic impacting gun, include the transducer and the luffing bar that links to each other with transducer that are arranged in the impact gun housing, and be the impact head that striker pin constituted of needle-like by the end other end that links to each other with the luffing bar, impact head and stretch out the impact gun housing, described luffing bar cooperates with the double inclined plane that all forms the inclined-plane on impact head and luffing bar that is connected to that impacts head, or on the luffing bar, form and face groove directly and match, or a kind of in matching of the sphere that on the luffing bar, forms inclined plane groove and impact with the sphere that impacts head.
Described impact head is 0 °～100 ° with the formed angle of luffing bar extended line.
Described transducer 1 adopts a kind of in piezoelectric transducer or the magnetostriction transducer.
Bevel angle ultrasonic impacting gun of the present invention, simple in structure, cheap, it is convenient to change, can flexible adaptation in the specific position and the angle of various labyrinths.Not only solve the compatible problem in space between ultrasonic impact gun and the processed workpiece, and made the resonant condition of impact process more stable, significantly improved treatment effeciency.Compare with existing non-angular impact gun, under identical input power, can make efficient improve 50～200%.
