Embodiment Construction
[0010] The specific embodiments of the present invention will be described in detail below in conjunction with the technical solutions and accompanying drawings.
[0011] Before the vulcanization fixture is assembled, the release agent is evenly sprayed on the outer surface of the positioning sleeve 6, the outer surface of the fixed seat 1 in contact with it, and the outer surface of the compression nut 9, so that the positioning sleeve 6 can be removed smoothly after vulcanization is completed. And compression nut 9 is convenient for cleaning vulcanized rubber.
[0012] A specific embodiment of a ring vulcanization method for a small cylindrical acoustic beacon piezoelectric ceramic ring with no ribs inside includes two aspects: assembly before vulcanization and disassembly after vulcanization. The assembly sequence before vulcanization is: first put the O-ring 2 on the attached figure 1 on the fixed seat 1 shown, then tighten the fixed seat 1 to the pressure-resistant housi...

The invention relates to a vulcanization method for a small-sized cylindrical acoustic beacon piezoelectric ceramic ring without rib grids inside and belongs to the technical field of ocean engineering. The method is characterized by comprising the steps that an inner thread and a lower end face of the lower portion of an acoustic beacon pressure-resistant shell are used as centering positioning references of the piezoelectric ceramic ring, and a fixing base is installed on the acoustic beacon pressure-resistant shell through a thread; the end face of the right side of the fixing base is usedfor positioning the position of the piezoelectric ceramic ring in the acoustic beacon pressure-resistant shell; an O-shaped ring installed on the fixing base is used for sealing a gap between a plastic spacer and the acoustic beacon pressure-resistant shell. The vulcanization method has the advantages that the effect is good, the method is simple, the structure is compact, few processing parts areneeded, and the ring is convenient to disassemble and assemble and can be repeatedly used. The method is mainly applied to vulcanization of the small-sized cylindrical acoustic beacon piezoelectric ceramic ring without rib grids inside.
Description
technical field [0001] The invention belongs to the technical field of marine engineering, and relates to a manufacturing method of a small acoustic beacon, in particular to a method for ring vulcanization of piezoelectric ceramic rings of a small cylindrical acoustic beacon with no ribs inside. Background technique [0002] In marine monitoring and marine engineering in the marine field, many marine parameter measurement equipment and instruments need to be recovered to obtain measurement data after the measurement is completed. However, due to the complex marine environment, equipment failure or other reasons, the equipment often does not surface normally or sink to the bottom of the sea, especially the important equipment with high cost, such as seabed-based platforms, side-scan sonar and If the underwater robot cannot be recovered normally, it will cause significant property loss, and more importantly, the measurement data cannot be obtained, which will cause the experim...
