Description

Technical Field

[0001] This utility model relates to the field of marine technology, and in particular to a cable sealing assembly tooling. Background Technology

[0002] The cable box sealing assembly mainly consists of the cable box, flange, molded rubber block, perforated plate, screw, and nut. Each component has ten locking holes evenly distributed on one side. Sealing must be performed after the cable laying is complete and the perforated plate is fully saturated with cable. With continuously increasing quality management requirements, the sealing process for cable boxes penetrating compartments in underwater products no longer relies solely on experience and visual inspection, but instead requires clear quantitative indicators for sealing effectiveness. For example, in a certain type of underwater product, it is explicitly stipulated that the compression of the molded rubber block must be controlled within the range of 6–10 mm.

[0003] However, under the current technological conditions, when using vernier calipers to measure the distance between the flange and the cable box at four positions (up, down, left, and right), the limited operating space makes the measurement process inconvenient and inaccurate, resulting in uneven compression of the rubber block and low precision in controlling the compression amount. Utility Model Content

[0004] This application provides a cable sealing assembly assembly tooling, which to some extent improves the technical problems of uneven rubber block compression and low compression control accuracy in related technologies.

[0005] This application provides a cable sealing assembly assembly fixture, which is used for assembling cable sealing assemblies. The cable sealing assembly includes a cable box, a rubber block, and two mounting units. The cable box is installed through the ship's bulkhead, the rubber block is disposed inside the cable box, and the two mounting units are respectively disposed at both ends of the cable box. Each mounting unit includes a flange, a perforated plate, and a lead screw. The perforated plate contacts the rubber block, and the flange is telescopically disposed at the end of the cable box. The flange includes a mounting plate and a push sleeve. The push sleeve contacts the rubber block, and the lead screw passes through the mounting plate and the cable box to adjust the distance between the mounting plate and the cable box. The assembly fixture includes a fixed part and a movable part. The movable part is telescopically connected to the fixed part to adjust the length of the assembly fixture. The assembly fixture can be positioned within the gap between the mounting plate and the cable box. One end of the assembly fixture contacts the end of the cable box, and the other end contacts the mounting plate to limit the distance between the mounting plate and the cable box, thereby limiting the compression of the rubber block.

[0006] In some embodiments, the movable part is telescopic relative to the fixed part, so that the length of the assembly tooling ranges from 37mm to 41mm.

[0007] In some embodiments, the fixing part has a first abutting surface that contacts the end of the cable box.

[0008] In some embodiments, the cable box includes a box body and a flange, the box body passing through the bulkhead of the ship, the flange being disposed at the end of the box body, passing through the mounting plate and the flange, and the first abutting surface contacting the flange.

[0009] In some embodiments, the movable part has a second abutment surface at the end away from the fixed part, and the second abutment surface contacts the mounting plate.

[0010] In some embodiments, the fixed part is provided with an internal threaded hole, the movable part is provided with an external thread, and the movable part is threadedly connected to the fixed part to adjust the length of the assembly tooling.

[0011] In some embodiments, the movable part includes a head and a rod, the external thread is disposed on the rod, the rod is threadedly connected to the fixed part, and the second abutment surface is disposed on the head.

[0012] In some embodiments, the assembly fixture further includes a stop nut, which is screwed onto the rod body and abuts against the fixing portion.

[0013] In some embodiments, the pitch of both the internal threaded hole and the external thread is 1.5 mm.

[0014] In some embodiments, both the fixed part and the movable part are made of stainless steel.

[0015] The beneficial effects of this application are as follows: This application provides a cable sealing assembly fixture that can be positioned within the gap between a mounting plate and a cable box. One end of the fixture contacts the end of the cable box, and the other end contacts the mounting plate, thus limiting the distance between the mounting plate and the cable box and consequently limiting the compression amount of the rubber block. In other words, simply placing the fixture within the gap between the mounting plate and the cable box allows for control of the rubber block's compression, improving compression accuracy and facilitating operation. Furthermore, since the fixture includes a fixed part and a movable part, with the movable part telescopically connected to the fixed part, the length of the fixture can be adjusted as needed to regulate the compression amount of the rubber block.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] It should be noted that all directional indications in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, where there is no conflict, the technical solutions of various embodiments can be combined with each other, and such combined technical solutions are also within the protection scope claimed by this utility model.

[0023] The cable box sealing assembly mainly consists of the cable box, flange, molded rubber block, perforated plate, screw, and nut. Each component has ten locking holes evenly distributed on one side. Sealing work must be carried out after the cable laying is completed and the perforated plate is fully saturated with cables. With the continuous improvement of quality management requirements, the sealing process of cable boxes penetrating compartments in underwater products no longer relies solely on experience-based construction and visual inspection, but instead requires clear quantitative indicators for sealing effectiveness. For example, in a certain type of underwater product, it is clearly specified that the compression of the molded rubber block must be controlled within the range of 6–10 mm.

[0024] However, under the current technological conditions, when using vernier calipers to measure the distance between the flange and the cable box at four positions (up, down, left, and right), the limited operating space makes the measurement process inconvenient and inaccurate, resulting in uneven compression of the rubber block and low precision in controlling the compression amount.

[0025] To improve the above-mentioned technical problems to a certain extent, this application provides a cable sealing assembly tooling that can improve the compression accuracy of the rubber block and is easy to operate.

[0026] The embodiments of this application are described below with reference to the accompanying drawings: Please see Figure 1 This application provides a cable sealing assembly assembly fixture 10, which is used for assembling cable sealing assemblies. The cable sealing assembly includes a cable box, a rubber block, and two mounting units. The cable box passes through the ship's bulkhead, the rubber block is disposed inside the cable box, and the two mounting units are disposed at both ends of the cable box and on both sides of the ship's bulkhead. The rubber block is disposed between the two mounting units.

[0027] The mounting unit includes a flange, a perforated plate, and a lead screw. The perforated plate contacts the rubber block. The flange is telescopically positioned at the end of the cable box and includes a mounting plate and a push sleeve. The push sleeve contacts the perforated plate. The lead screw passes through the mounting plate and the cable box, and engages with a nut to adjust the distance between the mounting plate and the cable box. When the distance between the mounting plate and the cable box decreases, the flange moves into the cable box, and the push sleeve pushes the perforated plate to compress the rubber block, thereby sealing the cable. Both mounting units must perform the same operation, compressing both sides of the rubber block. Currently, it is clearly stipulated that the compression amount of the molded rubber block must be controlled within the range of 6–10 mm, meaning the sum of the compression amounts on both sides of the rubber block must be within the range of 6–10 mm.

[0028] It should be noted that the cable box is roughly rectangular, with gaps between the four sides of the cable box and the mounting plate. Specifically, there are four gaps between the cable box end and the mounting plate, one vertically and one horizontally. Screws and nuts are used for adjustment between the mounting plate and each of the four sides of the cable box end. When adjusting the distance between the mounting plate and the cable box, the gaps between the mounting plate and the four sides of the cable box end must be equal to ensure uniform compression of the rubber block.

[0029] Please see Figure 1 In this embodiment, the cable sealing assembly fixture 10 includes a fixed portion 100 and a movable portion 200. The movable portion 200 is telescopically connected to the fixed portion 100 to adjust the length of the assembly fixture 10. The assembly fixture 10 can be positioned within the gap between the mounting plate and the cable box, with one end of the assembly fixture 10 contacting the end of the cable box and the other end contacting the mounting plate to limit the distance between the mounting plate and the cable box, thereby limiting the compression amount of the rubber block. Specifically, the movable portion 200 can telescopically extend relative to the fixed portion 100 so that the length of the assembly fixture 10 ranges from 37mm to 41mm.

[0030] The following example illustrates how to use the cable sealing assembly tool 10: 1) According to standard data, when the rubber block is in a relaxed state, the gap between the end of the cable box and the mounting plate is greater than 41mm. First, adjust the length of four assembly fixtures 10 to 41mm. Then, two workers operate from both sides of the bulkhead, placing the assembly fixtures 10 into the four gaps between the cable box and the mounting plate, ensuring that all four gaps are 41mm. Then, simultaneously tighten the lead screws on both sides of the bulkhead. After completion, proceed to the next inspection step. 2) During inspection, insert the 41mm long assembly tool 10 into the four gaps between the end of the cable box and the mounting plate. If the assembly tool 10 can be inserted into the gaps, it is considered qualified. After passing the test, proceed to the next step of construction. 3) One worker adjusts the length of assembly tool 10 to 37mm, and then places assembly tool 10 in the four gaps between one end of the cable box and the mounting plate. The other worker adjusts the length of assembly tool 10 to 38mm, and then places assembly tool 10 in the four gaps between the other end of the cable box and the mounting plate. Then, they tighten the rubber block with a wrench at the same time. The final compression of the rubber block is (41mm-37mm) + (41mm-38mm) = 7mm > 6mm, which meets the requirements. After the construction is completed, proceed to the next step of inspection. 4) During inspection, one worker places the 37mm long assembly tool 10 into the four gaps between one end of the cable box and the mounting plate, and another worker places the 38mm long assembly tool 10 into the four gaps between the other end of the cable box and the mounting plate. If both can be placed in the gaps, the cable is considered to be qualified and the cable sealing is completed. At this time, the rubber block is compressed evenly and the compression amount of the rubber block meets the requirements.

[0031] The cable sealing assembly fixture 10 provided in this application embodiment can be disposed within the gap between the mounting plate and the cable box. One end of the assembly fixture 10 contacts the end of the cable box, and the other end contacts the mounting plate, thereby limiting the distance between the mounting plate and the cable box and thus limiting the compression amount of the rubber block. In other words, simply placing the assembly fixture 10 within the gap between the mounting plate and the cable box allows control of the rubber block's compression amount, improving the compression accuracy of the rubber block, and is easy to operate. Furthermore, since the assembly fixture 10 includes a fixed part 100 and a movable part 200, and the movable part 200 is telescopically connected to the fixed part 100, the length of the assembly fixture 10 can be adjusted as needed to adjust the compression amount of the rubber block.

[0032] In some embodiments, the fixing part 100 has a first abutting surface 110 that contacts the end of the cable box. The first abutting surface 110 is planar, and its contact with the end of the cable box allows for a complete fit between the first abutting surface 110 and the end of the cable box. Similarly, the movable part 200 has a second abutting surface 221 at its end away from the fixing part 100, which contacts the mounting plate. This ensures that the length of the assembly fixture 10 is precisely equal to the gap length between the mounting plate and the end of the cable box, thereby improving the accuracy of the compression adjustment of the rubber block.

[0033] Specifically, the cable box includes a box body and side rails. The box body is installed through the ship's bulkhead, and the side rails are located at the ends of the box body. A lead screw passes through the mounting plate and the side rails, and the first contact surface 110 contacts the side rails. The box body is roughly rectangular, and there are four side rails, which are located on the four sides of the ends of the box body.

[0034] In some embodiments, the fixed part 100 is provided with an internal threaded hole, and the movable part 200 is provided with an external thread. The movable part 200 is threadedly connected to the fixed part 100 so that the movable part 200 can extend and retract relative to the fixed part 100, thereby adjusting the length of the assembly tooling 10. The first abutment surface 110 may be provided on the fixed part 100, and the second abutment surface 221 may be provided on the movable part 200.

[0035] In some embodiments, the movable part 200 includes a head 220 and a rod 210. The rod 210 is externally threaded and threaded to the fixed part 100 so that the rod 210 can extend and retract relative to the fixed part 100, thereby adjusting the length of the assembly tool 10. The second abutment surface 221 is provided on the head 220 to increase the contact area between the second abutment surface 221 and the mounting plate.

[0036] Specifically, the pitch of both the internal and external threads is 1.5mm, and both the fixed part 100 and the movable part 200 are made of stainless steel. Furthermore, the assembly fixture 10 includes a locking nut 300, which is screwed onto the rod body 210 and abuts against the fixed part 100. The locking nut 300 prevents accidental relative rotation and loosening between the movable part 200 and the fixed part 100, thereby locking their positions and ensuring the stability of the entire fixture.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
