Description

Technical Field

[0001] This invention relates to the field of underwater acoustic sensor positioning technology, and in particular to a tooling for bonding and positioning a vector hydrophone vibrator. Background Technology

[0002] Co-vibration vector hydrophones based on the principle of inertial acceleration sensors are stable and highly sensitive, and have been widely used in port safety monitoring systems and underwater noise source localization. Designers typically focus on the sensitivity and directivity of vector hydrophones. Sensitivity mainly depends on the performance of the internal sensing element, while directivity depends not only on the sensing element but also on the quality of the hydrophone's structural design and assembly. Currently, no similar tooling has been found in use, as tooling is related to each unit's own products and is part of the production process. Summary of the Invention

[0003] To address the shortcomings in the prior art, this invention provides a vector hydrophone oscillator bonding and positioning fixture. This fixture ensures good symmetry in the assembly positions of paired oscillators, and is easy to operate and portable and efficient in application.

[0004] The purpose of this invention is to provide a tooling for bonding and positioning vector hydrophone oscillators, comprising: substrate; Multiple bases are arranged in different ways on the substrate; Each base has a slot for placing the vector oscillator; Each tank is equipped with a wedge-shaped block, which is then forcefully embedded into the tank or loosened and removed from the tank via a connector. The vector oscillator is clamped to one side of the groove by a wedge-shaped block that is forcefully embedded, thus completing the positioning of the vector oscillator.

[0005] Preferably, the wedge block is forcefully embedded into the groove or loosened and ejected from the groove via a connector, including: Each base has a first through hole extending from the bottom of the tank away from the tank, and the substrate has a second through hole corresponding to each first through hole; A sliding rod is inserted into each of the second through holes and its corresponding first through hole. One end of the sliding rod, which passes through the first through hole, extends inward and is threadedly connected to the wedge block in the corresponding groove. The other end is provided with an annular protrusion. The diameter of the protrusion is larger than the diameter of the second through hole. The wedge block is inserted into the tank by rotating the sliding rod or loosened and removed from the tank.

[0006] Preferably, a compression spring is fitted on the portion of each sliding rod near the protrusion, and the sliding rod is pushed away from the wedge block by the compression spring pressing tightly against the protrusion; By pressing the protrusion of the sliding rod, the wedge block [3] is moved away from the groove, thus realizing the function of relaxing and disassembling the vector oscillator. By releasing the protrusion at the end of the sliding rod, the wedge block is moved into the groove under the action of the compression spring to realize the clamping function.

[0007] Preferably, the compression spring is embedded in the second through hole, or the compression spring is embedded in both the second through hole and part of the first through hole; In this process, the second through hole or part of the first through hole is expanded outward to embed a compression spring.

[0008] Preferably, the wedge block is made of metal and has a right-angled trapezoidal cross-section with a threaded hole in the middle of the upper base of the trapezoid; wherein, the right-angled side of the wedge block and the side of the groove are used to support the vector oscillator.

[0009] Preferably, the substrate has four bases evenly distributed along the circumferential direction, and each base holds a vector oscillator.

[0010] Preferably, the substrate is provided with positioning holes and positioning posts required for external assembly.

[0011] Preferably, multiple bases are integrated with the substrate.

[0012] Preferably, the side of each groove wall that forms a clamping surface with the wedge block is higher than the other side.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention provides a positioning fixture for bonding vector hydrophone transducers. The fixture comprises a sliding rod, a spring, a wedge block, a vector transducer, a base plate, and multiple bases mounted on the base plate. Four bases are evenly distributed along the circumference of the base plate, corresponding to four clamping interfaces. Each interface contains a right-angle positioning surface, which is a key reference for ensuring the spatial position of the vector transducer. The sliding rod passes through the spring, through a through-hole in the base, and connects to a threaded hole in the wedge block. Pressing the upper end of the sliding rod causes the wedge block to move downwards, enabling the vector transducer to be loosened and disassembled. Releasing the upper end of the sliding rod allows the wedge block to move upwards under the action of the spring, achieving the clamping function. This positioning fixture offers high assembly consistency, good operability, and is portable and efficient for bonding and positioning vector hydrophone transducers. Attached Figure Description

Detailed Implementation

[0015] The following describes several specific embodiments of the present invention in detail, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0016] The purpose of this invention is to provide a tooling for bonding and positioning vector hydrophone oscillators, which can ensure the consistency of the assembly position of each oscillator, and is highly reliable, easy to operate, and portable and efficient in application.

[0017] See Figures 1-3 As shown, a vector hydrophone transducer bonding and positioning fixture includes a base plate 5 and multiple bases 5-1; the multiple bases 5-1 are arranged on the base plate 5 in different ways; each base 5-1 has a groove for placing the vector transducer 4; each groove has a wedge block 3, and the wedge block 3 is forcefully embedded into the groove or loosened and removed from the groove by a connector; the vector transducer 4 is clamped to one side of the groove by the force of the wedge block 3 embedded in the groove, thus completing the positioning of the vector transducer 4.

[0018] This invention achieves the positioning of the vector oscillator by applying a support between one side of the wedge block and one side of the groove.

[0019] To achieve the clamping of the vector oscillator by the wedge block, the wedge block 3 is forcefully embedded into the groove or loosened and removed from the groove via a connector, including: Each base 5-1 has a first through hole extending from the bottom of the tank away from the tank, and the base plate 5 has a second through hole corresponding to each first through hole; a sliding rod 1 is inserted into each second through hole and its corresponding first through hole, one end of the sliding rod 1 extending inward into the first through hole and threadedly connected to the wedge block 3 in the corresponding tank, and the other end has an annular protrusion; the diameter of the protrusion is larger than the diameter of the second through hole; by rotating the sliding rod 1, the wedge block 3 is forcefully inserted into the tank or loosened and removed from the tank. Therefore, the sliding rod is a connecting component that allows the wedge block 3 to be forcefully embedded into the groove or loosened and disassembled from the groove. Each sliding rod 1 has a compression spring 2 fitted on the part near the protrusion. The compression spring 2 pushes the sliding rod 1 away from the wedge block 3 by pressing the protrusion. It can be seen that by pressing the protrusion of the sliding rod 1, the wedge block 3 is moved away from the groove, realizing the function of loosening and disassembling the vector oscillator 4. When the protrusion at the end of the sliding rod 1 is released, the wedge block 3 is moved into the groove under the action of the compression spring 2 to realize the clamping function.

[0020] To facilitate the rapid application and relaxation of the vector oscillator by the wedge block, the height of the side wall of each groove that forms a bearing surface with the wedge block 3 is higher than that of the other side.

[0021] To ensure the stability of the sliding rod when pressed, the compression spring 2 is embedded in the second through hole, or the compression spring 2 is embedded in both the second through hole and part of the first through hole; wherein, the second through hole or part of the first through hole is expanded outward to embed the compression spring 2 therein.

[0022] It should be noted that the present invention can process multiple bases 5-1 and substrate 5 into one piece. It can be seen that the first through hole and the corresponding second through hole will form an integral through hole.

[0023] In this invention, the wedge block 3 is made of metal and has a right-angled trapezoidal cross-section with a threaded hole in the middle of the upper base of the trapezoid; wherein, the right-angled side of the wedge block 3 and the side of the groove are used to support the vector oscillator 4.

[0024] In this invention, four bases 5-1 are evenly distributed along the circumferential direction on the substrate 5, and a vector oscillator 4 is attached to each base 5-1.

[0025] The substrate 5 is provided with positioning holes 7 and positioning posts 6 required for external assembly.

[0026] To further illustrate the vector hydrophone oscillator bonding and positioning fixture provided by this invention, see [link to relevant documentation]. Figures 1-3 As shown, the fixture consists of a sliding rod 1, a spring 2, a wedge block 3, a vector oscillator 4, a base plate 5, and multiple bases 5-1 disposed on the base plate 5. The sliding rod 1 is made of metal, with a threaded feature at its root and an annular protrusion at its top, resembling a bolt in shape. The spring 2 is a cylindrical compression spring with an inner diameter larger than the outer diameter of the sliding rod, and is installed at the outer end of the sliding rod 1. The wedge block 3 is made of metal, with a right-angled trapezoidal cross-section and a threaded hole in the middle of its upper base, through which the threaded end of the sliding rod 1 is connected. The vector vibrator 4 is a sensor sensing device unit, comprising a ceramic device and a metal substrate, which is clamped between the wedge block 3 and the base 5 on two vertical surfaces. The base 5 and each base 5-1 form the main body of the adhesive positioning fixture, which is made entirely of metal. The base 5 has four bases 5-1 evenly distributed around its circumference, corresponding to four clamping interfaces. Each interface has a right-angled positioning surface structure. The sliding rod 1 passes through the spring 2 and connects to the threaded hole on the wedge block 3 via the through hole on the base 5-1. The base 5 also contains positioning holes and positioning posts required for external assembly. Four bases 5-1 are evenly distributed in the circumferential direction of the substrate 5, corresponding to four clamping interfaces. Each interface contains a right-angle positioning surface structure. This right-angle positioning surface is the key reference to ensure the spatial position of the vector oscillator 4. The sliding rod 1 passes through the spring 2 and connects to the threaded hole on the wedge block 3 via the through hole on the base 5-1. By pressing the upper end of the sliding rod 1, the wedge block 3 can move downward, realizing the function of loosening and disassembling the vector oscillator 4. When the upper end of the sliding rod 1 is released, the wedge block 3 moves upward under the action of the spring 2 to realize the clamping function.

[0027] The sliding rod is made of stainless steel with an M3 thread at the bottom and a 6mm diameter annular protrusion at the top, for a total height of 25mm. The spring uses 0.6mm diameter stainless steel spring wire with 10 coils and a 2mm pitch. The wedge is made of hard aluminum, with the upper and lower bases of the right trapezoid being 4.5mm and 6mm respectively, and the right-angled side being 5mm long. The vector oscillator is rectangular in shape, with dimensions of 36mm × 22mm × 0.8mm. The base plate and each base are made of hard aluminum, with each base having a clamping interface size of 22mm × 5.6mm × 8mm and a 3.5mm diameter hole for the sliding rod.
