Abstract
The utility model discloses an index amplitude transformer for ultrasonic grinding. The index amplitude transformer is of a trumpet-shaped structure, wherein the front trumpet mouth of the trumpet-shaped structure is an input end, and the rear part of the trumpet-shaped structure is an output end. The index amplitude transformer can be used for improving the efficiency of ultrasonic grinding and reducing the heating of a connection part, so that the index amplitude transformer is suitable for use in ultrasonic grinding devices.
Description
Technical field
The utility model relates to a kind of horn,exponential, relates to a kind of horn,exponential that is applied to ultrasonic fine-lapping device efficiently especially.
Background technology
Ultrasonic amplitude transformer is claimed ultrasonic gear lever again, and its effect is to amplify the amplitude of ultrasonic vibration that transducer obtained, to satisfy the needs of Ultrasonic machining.Ultrasonic wave is mainly propagated with the compressional wave form in the metal bar bar, causes that each point is made double vibrations by sinusoidal rule in the original place along the direction of advance of ripple in the bar, and is transmitted to the instrument end face with the velocity of sound, and the instrument end face of making is done ultrasonic vibration.
Horn is amplified mechanical vibration displacement or velocity amplitude so that carry out machining, as the transducer amplitude be generally 4～10 μ m, and processing often need reach 10～100 μ m, this just must be by means of the amplification of horn; Horn makes transducer mate coupling acoustic energy with acoustic load better as the mechanical impedance converter.Amplitude that mechanical oscillation are excessive and too high frequency can make horn bear very big internal stress, can surpass the fatigue strength of horn material when serious, reduce its service life.Along with the increase of instrument vibration amplitude and frequency, strengthened the energy dissipation of junction between instrument and horn, horn and the transducer.Therefore the horn design plays an important role to the efficient of Ultrasonic machining.
Summary of the invention
The purpose of the utility model is to design a kind of a kind of horn,exponential efficient and simple in structure.
What the utility model will solve is the existing secondary bar inefficiency that becomes, and the coupling part is prone to heating and the high problem of its inner internal stress.
The purpose of the utility model realizes through following technical scheme:
Described horn,exponential is a flared structure, and the anterior horn mouth of flared structure is an input, and the rear portion is an output.
Described flared structure is from the arbitrary section diameter of a certain position of input
D(x) calculate according to following formula:
?D(x)=
In the formula,
