Description

Technical Field

[0001] This utility model relates to the field of clamping structures, specifically to a device for the installation and quick disassembly of cylindrical components in confined spaces. Background Technology

[0002] In the design of cylindrical structures within the confined space of aircraft hulls, the reliable fixation and maintenance of these cylindrical metal components are often crucial due to space constraints. Traditional methods involve manual removal of these components using large tools. However, these tools suffer from low precision (tolerance > 0.1mm) and wear easily after repeated disassembly, failing to meet the demands of repeated testing and maintenance of cylindrical metal components. Furthermore, after prolonged storage, the threaded connections between the cylindrical metal components and the hull are prone to rusting and seizing due to silicone rubber curing and air oxidation, requiring forceful disassembly. The limited space within the aircraft hull also restricts the accessibility of traditional wrenches or calipers, resulting in low maintenance efficiency. To address these issues, a specific device is needed that allows for easy installation and rapid disassembly of cylindrical metal components within confined spaces, with an operation method that enables reliable and repeated thread tightening and disassembly. Utility Model Content

[0003] The purpose of this invention is to provide a device for the installation and quick disassembly of cylindrical components in confined spaces to solve the aforementioned problems. This device offers the following advantages: 1. It overcomes the limitations of traditional tools that cannot be used in confined spaces, enabling effective deep-penetration operations in such environments; 2. After prolonged storage, the threaded connection between cylindrical metal parts and the housing is prone to rusting and seizing due to the curing of silicone rubber and oxidation, making removal and maintenance difficult. This device facilitates the easy disassembly of cylindrical metal parts. Traditional tools have large tolerances when used with cylindrical metal parts, resulting in severe wear after repeated installation and disassembly, failing to meet the needs of repeated use and maintenance. This device can meet the requirements of repeated installation and disassembly while ensuring no damage to the product surface and no adverse effects on product performance and structure.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a device for installing and quickly disassembling cylindrical components in confined spaces, comprising:

[0005] Connecting buckle, used to connect to cylindrical components;

[0006] The connecting fixture is connected to the connecting buckle.

[0007] The cylindrical components can be disassembled and installed by rotating the connecting fixture to drive the connecting buckle to rotate.

[0008] As a further improvement to the above technical solution:

[0009] The connection method between the connector and the cylindrical component is one or a combination of threaded connection, welding, and snap-fit. The connection method is selected based on the installation environment, with threaded connection being the most common choice.

[0010] The connecting fixture is provided with a receiving cavity for receiving the connecting buckle.

[0011] The number of connecting buckles shall be at least three. The number of connecting buckles may be less than the number of receiving cavities, but the positions of the connecting buckles and the receiving cavities shall correspond.

[0012] A flexible guide sleeve is provided at one end of the connecting tooling.

[0013] One end of the connecting fixture is provided with a mounting hole, and a turning handle passes through the mounting hole.

[0014] This utility model also discloses a method for installing and quickly disassembling cylindrical components in confined spaces, including the following steps:

[0015] S1. Secure the connector to the end of the cylindrical component. This step may require creating a threaded hole in the cylindrical component to allow for connection. When the connector and cylindrical component are self-locking and screwed together, a molybdenum disulfide solid lubricant can be applied to reduce the screwing torque.

[0016] S2. Connect the connecting fixture to the connecting buckle so that the connecting buckle extends into the receiving cavity;

[0017] S3. Insert the handle into the mounting hole and rotate it in the forward or reverse direction to disassemble or install, depending on the disassembly or installation task.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention utilizes a self-locking thread helix angle design and a tooling-connecting buckle linkage mechanism to achieve reliable positioning, installation, and quick disassembly of cylindrical metal parts in confined spaces. The self-locking thread design secures the connecting buckle to the cylindrical metal part. A specific tooling, through its internal structure, forms a self-locking torsional fit with the connecting buckle, rotating the cylindrical part to complete positioning, installation, and disassembly. This linkage component and method effectively improves worker efficiency in confined spaces, significantly shortening the effective working time of cylindrical metal parts in such spaces. Simultaneously, workers can independently apply torque to effectively retract the cylindrical metal part, solving the problem of traditional tools often requiring multiple people to work together. A tungsten carbide coating is sprayed onto the self-locking thread surface at the end of the connecting buckle, which enhances the self-locking force under high temperature and high pressure conditions compared to traditional threads. Vibration testing comparisons show that the tungsten carbide coating exhibits excellent vibration resistance, effectively preventing loosening and detachment of very small snap fasteners.

[0020] The entire process of positioning, installation, and rapid disassembly is achieved through a pure axial force operation using a self-locking torsion fit between the connecting fixture and the connecting buckle, effectively avoiding damage to the surface of metal parts. The connecting fixture has a simple structure, is easy to manufacture, and can be made of silicon carbide fiber-reinforced ceramic or titanium alloy, resulting in significant weight reduction compared to traditional steel tools. The connecting fixture and connecting buckle work together to disassemble cylindrical metal parts, effectively preventing damage to related mating components; installation and disassembly do not require consideration of wear on related parts. If stripping occurs between the square head of the connecting buckle and the groove in the connecting fixture, simply replace the connecting buckle and change the position of the groove in the connecting fixture to continue operation, significantly reducing maintenance costs.

[0021] This invention is applicable to the positioning, installation, and disassembly of parts within various confined cylindrical spaces. By modifying the structural diameter and end-face dimensions of the connecting fixture according to specific application scenarios, and machining self-locking threaded grooves on the outer surface of the parts within the confined cylindrical space to form a self-locking fit with the connecting buckle, the connecting fixture allows for simple and convenient reliable positioning, installation, and disassembly of parts within confined cylindrical spaces. It exhibits strong versatility and reliability. Attached Figure Description

[0031] like Figure 5 and Figure 6 As shown, the device for installing and quickly disassembling cylindrical components in confined spaces according to this embodiment includes:

[0032] Connector 1 is connected to cylindrical component 2; such as Figure 1 The diagram shows cylindrical component 2, installed inside pipe 4, which is inconvenient to disassemble. (Example:) Figure 2 As shown, the connecting buckle 1 in this embodiment has a threaded structure. The tail end of the connecting buckle 1 is machined with a thread, the helix angle α being 4°~8° (preferably 6°), satisfying tanα<μ (μ≥0.2). The thread surface is coated with a tungsten carbide coating (thickness 20~25μm), maintaining a friction coefficient μ≥0.25 at high temperatures. A stress relief groove (0.3mm wide) is provided at the thread root to prevent stress concentration leading to breakage. The cylindrical component 2 and the pipe 4 are connected by a threaded connection. The pipe 4 cannot rotate, therefore the cylindrical component 2 needs to be rotated for assembly. A self-locking thread groove matching the thread of the connecting buckle 1 is machined on the inner wall of the tail end of the cylindrical component 2. This thread groove can engage and lock with the connecting buckle 1. The thread groove and the snap fastener use an H7 / m6 interference fit, with a single-sided interference of 0.02~0.05mm.

[0033] The connecting fixture 3 is provided with a receiving cavity 31, which is used to receive the connecting buckle 1. There are 6 connecting buckles 1 and 6 receiving cavities 31. The receiving cavity 31 is relatively long, designed to be at least 1 / 2 the length of the connecting fixture 3, so as to meet the installation of various depth dimensions.

[0034] The cylindrical component 2 can be disassembled and installed by rotating the connecting fixture 3 to drive the connecting buckle 1 to rotate.

[0035] A flexible guide sleeve 32 is provided at one end of the connecting fixture 3. The flexible guide sleeve 32 is made of silicone to prevent the connecting fixture 3 from damaging the surface of the cylindrical component 2. The connecting fixture 3 can be made of silicon carbide fiber reinforced ceramic material (density 2.5g / cm3) to achieve effective weight reduction and single-person handheld operation. The internal receiving cavity 31 of the connecting fixture 3 has a square cross-section.

[0036] One end of the connecting fixture 3 is provided with a mounting hole 33, and a turning handle 34 passes through the mounting hole 33. For ease of operation, the rotating connecting fixture is made easier by inserting the turning handle 34.

[0037] This embodiment also discloses a method for using the device for installing and quickly disassembling cylindrical components in confined spaces, including the following steps:

[0038] S1. Fix the connecting buckle 1 to the end of the cylindrical component 2; install the connecting buckle 1 onto the cylindrical component 2 through a threaded connection.

[0039] S2. Connect the connecting fixture 3 to the connecting buckle 1 so that the connecting buckle 1 extends into the receiving cavity 31. The receiving cavity 31 here is a side-closed cavity or a partially closed cavity structure, so that the connecting buckle 1 can extend into the receiving cavity 31. Its shape can be modified according to the shape of the connecting buckle 1.

[0040] S3. Insert the handle 34 through the mounting hole 33. Depending on the disassembly or installation task, rotate the handle 34 in the forward or reverse direction to achieve disassembly or installation.

[0041] This invention is applicable to the positioning, installation, and disassembly of parts within various confined cylindrical spaces. By modifying the structural diameter and end-face dimensions of the connecting fixture according to specific application scenarios, and machining self-locking threaded grooves on the outer surface of the parts within the confined cylindrical space to form a self-locking fit with the connecting buckle, the connecting fixture allows for simple and convenient reliable positioning, installation, and disassembly of parts within confined cylindrical spaces. It exhibits strong versatility and reliability.
