A kind of sound wave transducer making holder

Abstract

The invention discloses a clamp holder for manufacturing an acoustic transducer. The clamp holder comprises a bottom plate assembly, a plurality of transducer assemblies which are stacked together areplaced in the center of the bottom plate assembly, a forward correcting assembly, a forward fixing assembly, a lateral correcting assembly and a lateral fixing assembly are arranged on the bottom plate assembly, wherein the forward correcting assembly and the forward fixing assembly are used for providing clamping and limiting in the X-axis direction for the transducer assemblies respectively, the lateral correcting assembly and the lateral fixing assembly are used for providing clamping and limiting in the Y-axis direction for the transducer assemblies respectively, the bottom plate assemblyis further connected with a jacking plate assembly used for providing clamping in the Z-axis direction for the transducer assemblies, the jacking plate assembly is connected with a weight disc used for providing the constant Z-axis direction clamping force, and two sides of the transducer assemblies are connected with sliding block assemblies matched with the lateral correcting assembly and the lateral fixing assembly correspondingly. According to the clamp holder for manufacturing the acoustic transducer, bonding and manufacturing of the single transducer can be performed, bonding and manufacturing of the plurality of transducers can also be carried out, in the bonding and manufacturing process, the clamping force is kept unchanged along with the change of the temperature, so that the bonding and manufacturing quality of the transducer is guaranteed.

Description

technical field [0001] The invention relates to oil well logging technology, in particular to a clamping device used for adhesive production of well logging acoustic wave transducers, which can be used for research and development and mass production of acoustic wave transducers. Background technique [0002] Acoustic logging is a kind of logging method that judges the geological characteristics of the wellbore formation and the engineering status of the wellbore by measuring the acoustic properties of the wellbore medium. In petroleum logging technology, the application of acoustic logging is the most extensive, which belongs to the category of this method: compensated acoustic logging, long source distance acoustic logging, array acoustic logging, dipole acoustic logging, etc. [0003] Acoustic transducer is the key component of acoustic logging tool, its quality directly affects the correctness and stability of acoustic logging curve. The production of domestic well logg...

AI Technical Summary

Problems solved by technology

However, the bonding of logging acoustic wave transducers requires a long high-temperature curing process. As the temperature changes, the clamping force of the holder will change with the thermal expansion and contraction of its own parts, thus affecting the energy conversion. impact on the quality and consistency of
