AI Technical Summary
Technical Problem
Existing thin-walled spherical hydrophones are prone to breakage during vulcanization due to torsional stress concentration, resulting in a low yield.
Method used
The design employs a hemispherical contact surface between a stainless steel spindle and a universal spherical nylon adapter shaft. Combined with the design of a half-type vulcanization mold, this achieves a coaxial arrangement of the piezoelectric ceramic ball, rigid foam gasket, universal spherical nylon adapter shaft, and stainless steel spindle. Furthermore, the design eliminates torsional stress by covering the spindle with vulcanized rubber.
Benefits of technology
This effectively prevents the thin-walled spherical hydrophone from breaking during the vulcanization process, thus improving the product yield.

Abstract
The application provides a thin-wall spherical hydrophone anti-breaking vulcanization structure, which comprises a piezoelectric ceramic ball, a hard foam gasket, a universal follow-up spherical nylon adapter shaft, a stainless steel main shaft, vulcanized rubber and a half vulcanization mold, wherein the piezoelectric ceramic ball, the hard foam gasket, the universal follow-up spherical nylon adapter shaft and the stainless steel main shaft are sequentially arranged from inside to outside of the half vulcanization mold; the spherical contact surface in the middle of the universal follow-up spherical nylon adapter shaft is connected with the stainless steel main shaft, and the two are rotationally matched through the spherical contact surface. The half-spherical contact surface between the stainless steel main shaft and the universal follow-up spherical nylon adapter shaft is connected, so that when the piezoelectric ceramic ball opening is subjected to torsional stress, the rotation matching of the half-spherical contact surface can avoid the problem of torsional stress concentration, thereby reducing the occurrence of the spherical breaking problem of the thin-wall spherical hydrophone in the vulcanization process, and further improving the product yield.
