Abstract
The utility model discloses a 3/2 wavelength ultrasonic impact gun comprising a half-wavelength ultrasonic transducer, a full wavelength ultrasonic horn and an impact head, and the full wavelength ultrasonic horn is the lengthened small ultrasonic horn. The use of the 3/2 wavelength ultrasonic impact method can adjust the processing angle in a larger range under the situation of not affecting a slender gun front end and the strong adaptability to narrow space of the 3/2 wavelength ultrasonic impact gun, thereby being applicable to the needs on a processed surface; the method has big output power, convenient use, simple structure and low cost.
Description
Technical field
The utility model relates to a kind of ultrasonic impact gun, relates in particular to a kind of physical construction fatigue property that improves, and eliminates unrelieved stress and surface-treated ultrasonic impact gun.
Background technology
Methods such as present stage is main both at home and abroad adopts that TIG moltenly repaiies, hammering and shot-peening improve the fatigue property of mechanical part and structure, but these method labour intensity are big, energy consumption is high and can have a negative impact.Ultrasonic impact is light and handy with its topworks, and controllability is good, flexible and convenient to use, noise is minimum, efficient is high, limited few when using, advantage such as cost is low and energy-conservation is applicable to various terminal, is the method that a kind of ideal postwelding improves fatigue properties of welded joints.
This method generally is divided into piezoelectric ceramic type and magnetostriction type, adopts the long design of all-wave to convert electrical energy into mechanical vibration shock treatment weld face, improves the purpose of eliminating unrelieved stress fatigue lifetime to reach.This method has the shortcoming that can't overcome, and as shown in Figure 1, for the structure of small space and some specific positions or size, the position that is easy to generate fatigue problem as tubule (caliber is less than Φ 300mm) and narrow deep trouth etc. is then powerless.
In order to solve the problems of the technologies described above, be necessary newly developedly a kind ofly can improve the physical construction fatigue property to the small space or the specific position (such as tubule, deep trouth etc.) of workpiece, eliminate unrelieved stress and surface-treated ultrasonic impact rifle, impact head can't touch the corner location of workpiece.
Summary of the invention
Technical problem to be solved in the utility model is, can't touch the shortcoming of the small space or the specific position of workpiece at existing ultrasonic impact gun, providing a kind of can improve the physical construction fatigue property to the small space or the specific position of workpiece, eliminates unrelieved stress and surface-treated ultrasonic impact gun.
In order to solve the problems of the technologies described above, the utility model proposes following technical scheme:
A kind of 3/2 wavelength ultrasonic impact gun, the long ultrasonic amplitude transformer of all-wave rear end connects a half-wavelength ultrasonic transducer, is loaded in the housing, and the long ultrasonic amplitude transformer front end of all-wave is fixed an impact head, and the long ultrasonic amplitude transformer of described all-wave is the tiny ultrasonic amplitude transformer of lengthening.Because the lengthening of the long ultrasonic amplitude transformer of all-wave, impact head can touch small space or some specific position of workpiece, not only can process common workpiece, and can process the workpiece of distinctive appearance, uses more convenient and extensive.The concrete length of the long ultrasonic amplitude transformer of all-wave and fineness degree can be determined according to the needs of workpiece.
Described half wave length ultrasonic transverter is flexible transverter of half-wavelength magnetic hysteresis or half-wavelength PZT (piezoelectric transducer).
The beneficial effects of the utility model are remarkable, be specially: 1. adopt 3/2 wavelength ultrasonic impact method, have elongated rifle body front end, strong not influencing 3/2 wavelength ultrasonic impact gun, and can adjust process angle in a wider context, to adapt to the needs of machined surface for the adaptability of narrow space; 2. this method output rating is big and easy to use; 3. simple in structure, with low cost.

Embodiment
As shown in Figure 2, a kind of 3/2 wavelength ultrasonic impact gun, the long ultrasonic amplitude transformer of all-wave 2 rear ends connect a half-wavelength ultrasonic transducer 1, are loaded in the housing 5, long ultrasonic amplitude transformer 2 front ends of all-wave connect an impact head 3, and the long ultrasonic amplitude transformer 2 of described all-wave is the tiny ultrasonic amplitude transformer of lengthening.Because the lengthening of the long ultrasonic amplitude transformer 2 of all-wave, impact head 3 can touch small space or some specific position of workpiece 4, not only can process common workpiece, and can process the workpiece 4 of distinctive appearance, uses more convenient and extensive.The concrete length of the long ultrasonic amplitude transformer 2 of all-wave and fineness degree can be determined according to the needs of workpiece.
In the present embodiment, the long ultrasonic amplitude transformer 2 of all-wave can be by being formed by connecting two half wave length ultrasonic horn, and also die sinking tool in addition adopts longer ultrasonic amplitude transformer.
Described half wave length ultrasonic transverter 1 is flexible transverter of half-wavelength magnetic hysteresis or half-wavelength PZT (piezoelectric transducer).
As shown in Figure 3 and Figure 4, the utility model is processed some specific positions of workpiece 4, to improve the physical construction fatigue property, eliminates unrelieved stress and surface treatment.
