Description

Technical Field

[0001] This utility model relates to the field of electronic equipment testing technology, specifically to a special sieve assembly device for underwater vehicles. Background Technology

[0002] After the underwater vehicle signal processor is assembled and debugged, it needs to undergo a comprehensive environmental stress screening test to eliminate potential defects in the manufacturing process and ensure product reliability. This process requires a specialized clamping device to fix the signal processor in a comprehensive environmental stress screening test bench that withstands vibration, temperature, and humidity stresses.

[0003] Currently, the industry mostly uses fixed clamping devices. These devices typically consist of a base plate, handle, and multiple mounting brackets welded together into a rigid, monolithic structure. They can only clamp a single signal processor for testing at a time, and the positions of the mounting brackets are permanently fixed after welding, making any movement or adjustment impossible. Different models or batches of underwater vehicle signal processors may have different dimensions and mounting hole positions. When product dimensions change, existing fixed devices cannot adjust the relative positions of the mounting brackets, resulting in incompatibility and poor versatility. Once a product is upgraded, a redesign is necessary to meet the clamping requirements of the new product, increasing equipment costs and wasting existing tooling. Therefore, this invention proposes a dedicated underwater vehicle sieve assembly device to address these problems. Utility Model Content

A sliding mechanism is provided along the radial direction of the base for each of the assembly mechanisms, and the sliding mechanism is used to adjust the position of the signal processor relative to the base; A synchronization adjustment mechanism is disposed among the plurality of sliding mechanisms to achieve synchronous adjustment of the signal processor.

[0006] Preferably, a sliding groove is provided on the edge of the base for each sliding mechanism, and the sliding groove extends outward along the radial direction of the base.

[0007] Preferably, the sliding mechanism includes: a slide rail and a slide bar. Each sliding groove has a slide rail on its two opposite inner walls. One slide bar is provided for each slide rail. The slide bar and the slide rail are slidably connected. Each slide bar has a connecting block facing upward. Each connecting block has a sliding plate parallel to the base. The assembly mechanism is provided on the sliding plate.

[0008] Preferably, the assembly mechanism includes: a U-shaped frame, the two vertical sides of the U-shaped frame being detachably connected to the sliding plate, the horizontal side of the U-shaped frame being perpendicular to the radial direction of the base, the sliding plate being provided with an assembly groove adapted to the vertical side of the U-shaped frame, a pair of assembly holes being provided at both ends of the sliding plate near the assembly groove, the assembly holes respectively penetrating the opposite side walls of the assembly groove, the two vertical sides of the U-shaped frame being provided with insertion holes adapted to the assembly holes, and the U-shaped frame and the sliding plate being connected by a connector penetrating through the assembly holes and the insertion holes.

[0009] Preferably, a first extension and a second extension are respectively provided on the two vertical sides of the U-shaped frame away from the center of the base. The first extension is close to the horizontal side of the U-shaped frame. After the U-shaped frame and the mounting groove are detachably connected, the second extension abuts against the sliding plate. The U-shaped frame, the first extension, and the second extension are each provided with a plurality of mounting holes evenly distributed.

[0010] Preferably, a fixing plate is provided at each of the two ends near the bottom of the sliding plate. One end of the fixing plate is perpendicularly connected to the bottom of the sliding plate, and the other end of the sliding plate is provided with two sets of sliding wheels. Each set of sliding wheels is rotatably connected to the sliding plate, and the bottom of the sliding wheel abuts against the base.

[0011] Preferably, the synchronous adjustment mechanism includes: a positioning cylinder, which is disposed at the center of the bottom of the base, a rotating ring is sleeved on the positioning cylinder, the rotating ring and the positioning cylinder are rotatably connected, the rotating ring is provided with an arc-shaped groove corresponding to each of the slide bars, the arc-shaped groove extends from the positioning cylinder in a vortex shape towards the edge of the rotating ring, each slide bar is provided with a limit rod corresponding to one of the arc-shaped grooves, one end of the limit rod is vertically connected to the slide bar, the other end passes through the arc-shaped groove and is slidably connected to the arc-shaped groove, the limit rod is provided with a limit block, the limit block is slidably connected to the edge of the arc-shaped groove of the rotating ring.

[0012] Preferably, the outer edge of the rotating ring is evenly provided with a plurality of teeth, and a gear is provided near the rotating ring. The gear meshes with the teeth. The gear is provided with a rotating rod. One end of the rotating rod is connected to the center of the gear, and the other end rotatably passes through the base and is provided with a handle.

[0013] Preferably, a plurality of operating levers are evenly arranged on the outer edge of the base.

[0014] The underwater vehicle-specific sieve assembly device provided by this utility model has the following beneficial effects: 1. This utility model uses a sliding mechanism, one of which is provided along the radial direction of the base for each assembly mechanism. The sliding mechanism is used to adjust the position of the signal processor on the base. When facing signal processors of different specifications, it adjusts the space between multiple signal processors. The sliding mechanism is used to adjust the position of the signal processor relative to the base. A synchronous adjustment mechanism is provided between multiple sliding mechanisms to realize the synchronous adjustment of the signal processor, improve its adjustment efficiency, and enhance its adaptability to signal processors. The installed signal processors are also more flexible. 2. This utility model also achieves synchronous adjustment of multiple sliding mechanisms by limiting the limiting rod and the arc-shaped slide groove when the rotating ring rotates relative to the positioning cylinder. This is because the limiting rod slides relative to the two ends of the arc-shaped slide groove when the rotating ring rotates in the forward or reverse direction, and the slide bar connected to the limiting rod slides relative to the two ends of the slide rail. This improves the adjustment efficiency. 3. This utility model also allows the rotating rod to rotate relative to the base by operating the handle, which in turn drives the gear transmission to the rotating ring with meshing teeth, thereby achieving the rotation of the rotating ring relative to the positioning cylinder and thus achieving synchronous adjustment of it.

[0017] like Figure 1-5 As shown, this utility model provides a special assembly device for a comprehensive screening system for underwater vehicles, which includes: The base 1 provides support for mounting signal processors. At least three assembly mechanisms are evenly distributed around the center of the base 1, allowing for the mounting of multiple signal processors. These assembly mechanisms secure the signal processors for comprehensive environmental stress screening tests. A sliding mechanism is provided along the radial direction of the base 1, corresponding to each assembly mechanism. This sliding mechanism adjusts the position of the signal processors on the base 1, regulating the space between different sizes of signal processors. A synchronous adjustment mechanism is positioned between the sliding mechanisms to achieve synchronous adjustment of the signal processors, improving adjustment efficiency and adaptability, and increasing the flexibility of the mounted signal processors.

[0018] In some implementations, such as Figure 1-5 As shown, a sliding groove 2 is provided on the edge of the base 1 for each sliding mechanism. The sliding groove 2 extends outward along the radial direction of the base 1, so that when multiple signal processors are installed, they can be adjusted along the direction of the sliding groove 2 according to their corresponding specifications.

[0019] In some implementations, such as Figure 1-5As shown, the sliding mechanism includes a slide rail 3 and a slide bar 4. Each sliding groove 2 has two opposing inner walls provided with a slide rail 3, and one slide bar 4 is provided for each slide rail 3. By sliding the slide bar 4 within the slide rail 3, the assembly mechanism connected above it can be adjusted radially relative to the base 1. The slide bar 4 and the slide rail 3 are slidably connected. Each slide bar 4 has a connecting block 5 facing upwards. The connecting block 5 is vertical and aligned with the extension direction of the slide bar 4. The connection can be by bolting, bonding, or snap-fitting. Each connecting block 5 has a connection point with the base 1. Parallel sliding plates 6 are arranged perpendicularly to the sliding strip 4 and parallel to the base 1. The connection between the sliding plates 6 and the connecting block 5 can be by bolt connection or snap-fit. The assembly mechanism is provided on the sliding plates 6. When multiple assembly mechanisms are provided, if the specifications of the signal processors meet the requirements for simultaneous installation, they can be installed by adjusting the sliding mechanism. If the specifications do not meet the requirements, the number of signal processors installed can be reduced, and then the sliding mechanism can be adjusted so that the reduced number of signal processors can cope with the impact of the specifications.

[0020] In some implementations, such as Figure 1-5 As shown, the assembly mechanism includes: a U-shaped frame 7, the two vertical sides of the U-shaped frame 7 being detachably connected to the sliding plate 6, the horizontal side of the U-shaped frame 7 being perpendicular to the radial direction of the base 1, and the sliding plate 6 having an assembly groove 8 adapted to the vertical side of the U-shaped frame 7. The assembly groove 8 corresponds to the vertical side of the U-shaped frame 7 and is close to the two end edges of the sliding plate 6. A pair of assembly holes 9 are respectively provided at both ends of the sliding plate 6 near the assembly groove 8, and the assembly holes 9 respectively penetrate the opposite sides of the assembly groove 8. The U-shaped frame 7 has two vertical sides with insertion holes 10 that are adapted to the mounting hole 9. The U-shaped frame 7 and the sliding plate 6 are connected by a connector 11 that passes through the mounting hole 9 and the insertion hole 10. The connector 11 can be a screw with the same thread in the mounting hole 9 and the insertion hole 10. After the U-shaped frame 7 extends into the mounting groove 8 through the two vertical sides, the screw passes through the mounting hole 9 and the insertion hole 10, and the U-shaped frame 7 is detachably connected to the sliding plate 6 by means of a threaded connection.

[0021] In some implementations, such as Figure 1-5As shown, the U-shaped frame 7 has a first extension 12 and a second extension 13 on its two vertical sides away from the center of the base 1. The first extension 12 and the second extension 13 provide more mounting points and leverage points for the signal processor on the U-shaped frame 7. The first extension 12 is close to the horizontal side of the U-shaped frame 7 and connects the horizontal and vertical sides of the U-shaped frame 7 to increase the overall stability of the U-shaped frame 7. After the U-shaped frame 7 and the mounting groove 8 are detachably connected, the second extension 13 abuts against the sliding plate 6. The second extension 13 serves to limit and support the U-shaped frame 7 on the sliding plate 6, so that the U-shaped frame 7 can be stably supported on the sliding plate 6 after being assembled in the mounting groove 8. The U-shaped frame 7, the first extension 12 and the second extension 13 are each uniformly provided with a plurality of mounting holes, which can be screw holes, and the signal processor is fixed relative to the U-shaped frame 7 using bolts.

[0022] In some implementations, such as Figure 1-5 As shown, fixed plates 14 are respectively provided at both ends near the bottom of the sliding plate 6. One end of the fixed plate 14 is perpendicularly connected to the bottom of the sliding plate 6. The connection can be by bolt, welding or snap-fit. The fixed plate 14 further provides support for both sides after the sliding plate 6 and the slide bar 4 are connected. Two sets of sliding wheels 15 are provided at the other end of the sliding plate 6. Each set of sliding wheels 15 is rotatably connected to the sliding plate 6, and the bottom of the sliding wheel 15 abuts against the base 1. The sliding wheels 15 are commercially available. The sliding wheels 15 can be rotatably connected to the fixed plate 14 through a rotating shaft. Sliding wheels 15 are respectively provided at both ends of the rotating shaft. The sliding wheels 15 roll on the base 1 and provide support for the sliding plate 6 by rolling friction. This makes it easier to adjust the position of the U-shaped frame 7 relative to the center of the base 1, with less impact from friction.

[0023] In some implementations, such as Figure 1-5As shown, the synchronous adjustment mechanism includes: a positioning cylinder 16, which is located at the center of the bottom of the base 1. The connection can be by bolting, welding, or snap-fit. A rotating ring 17 is fitted onto the positioning cylinder 16. A limiting ring is provided on the positioning cylinder 16 to allow the rotating ring 17 to rotate on the positioning cylinder 16, preventing it from disengaging. The rotating ring 17 and the positioning cylinder 16 are rotatably connected. Each slider 4 has an arc-shaped groove 18 corresponding to an arc-shaped slide rail 4. The arc-shaped slide rail 18 extends from the positioning cylinder 16 in a vortex shape towards the edge of the rotating ring 17. Each slider 4 has a limiting rod 19 corresponding to one arc-shaped slide rail 18. One end of the rod 19 is vertically connected to the slide bar 4, and the other end passes through the arc-shaped slide groove 18 and is slidably connected to the arc-shaped slide groove 18. When the rotating ring 17 rotates relative to the positioning cylinder 16, due to the limitation of the limiting rod 19 and the arc-shaped slide groove 18, when the rotating ring 17 rotates in the forward or reverse direction, its limiting rod 19 slides relative to the two ends of the arc-shaped slide groove 18, and the slide bar 4 connected to the limiting rod 19 slides relative to the two ends of the slide rail 3, thereby realizing the synchronous adjustment of multiple sliding mechanisms to improve the adjustment efficiency. A limiting block 20 is provided on the limiting rod 19, and the limiting block 20 is slidably connected to the edge of the arc-shaped slide groove 18 of the rotating ring 17 to prevent the limiting rod 19 and the arc-shaped slide groove 18 from separating during sliding.

[0024] In some implementations, such as Figure 1-5 As shown, the outer edge of the rotating ring 17 is evenly provided with a plurality of teeth 21, and a gear 22 is provided near the rotating ring 17. The gear 22 is commercially available. The gear 22 meshes with the teeth 21. The gear 22 is provided with a rotating rod 23. One end of the rotating rod 23 is connected to the center of the gear 22, and the other end rotatably passes through the base 1 and is provided with a handle. By operating the handle, the rotating rod 23 rotates relative to the base 1, thereby driving the gear 22 to transmit power to the rotating ring 17 that meshes with the teeth 21, realizing the rotation of the rotating ring 17 relative to the positioning cylinder 16, and thus realizing synchronous adjustment of it.

[0025] In some implementations, such as Figure 1-5 As shown, multiple operating rods 24 are evenly arranged on the outer edge of the base 1. The connection between the operating rods 24 and the base 1 can be by bolt connection, welding, or snap-fit. The operating rods 24 facilitate the handling of the base by the operator.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
