Universal adjustable tool clamp for testing underwater acoustic transducer

Abstract

The invention discloses a universal adjustable tool clamp for testing an underwater acoustic transducer, and relates to the field of underwater acoustic transducers. The tool clamp comprises an I-shaped frame, and a U-shaped hole groove is formed in an upper beam of the I-shaped frame and used for being connected with a rotation device; two horizontal and vertical universal supports are fixedly arranged on a lower beam of the I-shaped frame and are separately positioned on two sides of the axis of the I-shaped frame, and the distance between the two supports and the axis of the I-shaped frameis adjusted to adapt to to-be-tested transducers with different sizes; and the horizontal and vertical universal supports are provided with connecting holes for the lower beam of the I-shaped frame topenetrate through during horizontal and vertical direction testing, the horizontal and vertical universal supports are provided with connecting holes for a planar transducer to be connected with theI-shaped frame during testing in the direction perpendicular to the connecting hole of the I-shaped frame, and the connecting holes are used for being connected with the to-be-tested transducers. According to the tool clamp, the problems that a traditional testing clamp is long in machining period and high in material cost, and efficiency is low due to the fact that different clamps need to be replaced when different types of transducers and different direction parameters of the same transducer are tested are solved.

Description

technical field [0001] The invention relates to the field of underwater acoustic transducers, in particular to a general-purpose adjustable fixture for testing underwater acoustic transducers. Background technique [0002] In the daily testing of underwater acoustic transducers, due to the wide variety of transducers with different shapes and sizes, it is necessary to process different fixtures during the test. If the same transducer is horizontally and vertically If testing is required, the corresponding test fixtures need to be processed, and it is difficult to be universal between the original test fixtures of different transducers. [0003] In addition, for the original test fixture, the main body of the test fixture needs to be replaced when testing in different directions, and the distance between the mounting holes on the horizontal test fixture is fixed, so only transducers of matching sizes can be tested; hydrophone or longitudinal transducer test fixtures, The siz...
