Description

Technical Field

[0001] This invention belongs to the field of electromechanical assembly technology, and mainly relates to an assembly tool for cable installation open sleeves. Background Technology

[0002] In the electromechanical industry, especially for cables, liquid cooling pipelines, and hydraulic pipelines in electronic equipment, long-term operation in harsh environments such as strong ultraviolet radiation, continuous vibration, and metal friction can easily lead to material aging, wear, and cuts, resulting in failure risks. To address this challenge, the industry commonly uses externally wrapped open-ended self-winding nylon textile sleeves as a protective solution. These sleeves possess excellent abrasion resistance and self-tightening properties, making them the current mainstream physical protection method.

[0003] However, the existing methods for installing protective sleeves still rely mainly on manual operation, which severely restricts assembly efficiency and quality stability. Because the nylon sleeves made of textile materials with axial openings have a natural tendency to shrink in a free state, operators need to constantly straighten and correct the opening edges manually during the wrapping process to prevent them from twisting and shrinking back. This process not only consumes a lot of energy but also causes frequent interruptions in the work rhythm, significantly reducing work efficiency. Furthermore, defects such as sleeve overlap, twisting, and wrinkles are very likely to occur during manual wrapping, which not only affects the appearance quality but also makes it easy for local delamination, loosening, or even slippage to occur under long-term vibration, leading to failure of the protective function, creating safety hazards, and directly increasing manufacturing costs and rework rates.

[0004] Therefore, there is an urgent need to develop an auxiliary assembly device with a reasonable structure and simple operation to fundamentally solve the problems of shrinkage, twisting, wrinkling and inefficiency in manual operation. Summary of the Invention

[0005] To address the problems in the prior art, this invention proposes an assembly tool for cable installation open sleeves, which has a reasonable structure and is easy to operate, and can solve the problems of shrinkage, twisting, wrinkling and inefficiency in manual operation.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0007] An assembly tool for installing open sleeves for cables, used to assemble open sleeves and cables, includes a left clamping ring, a right clamping ring, a pin, and a torsion spring. The torsion spring is sleeved on the pin, and the pin is hinged to the left and right clamping rings. The left and right clamping rings form a clamping structure that can be rotated and opened around the pin. The left and right clamping rings are respectively provided with a left guide rail and a right guide rail for unfolding the open sleeve. The cable is clamped between the left and right guide rails. The open sleeve passes through the left and right guide rails and is flattened, and then shrinks and naturally curls to wrap around the outside of the cable.

[0008] Furthermore, the left clamp ring and the right clamp ring respectively include a left handle portion and a right handle portion, and both the left handle portion and the right handle portion are covered with rubber for anti-slip or raised anti-slip ripples.

[0009] Furthermore, the left clamping ring and the right clamping ring respectively include a left clamping part and a right clamping part. The left clamping part includes a left inner clamping ring and a left outer clamping ring, both of which have arc-shaped cross-sections. The two form a left guide rail with one end open and the other end connected, and there is a gap between the two. The right clamping part includes a right inner clamping ring and a right outer clamping ring, both of which have arc-shaped cross-sections. The two form a right guide rail with one end open and the other end connected, and there is a gap between the two.

[0010] Furthermore, the openings of the left inner clamping ring and the left outer clamping ring are located on the side where the left clamping part connects to the left handle part, and the openings of the right inner clamping ring and the right outer clamping ring are located on the side where the right clamping part connects to the right handle part.

[0011] Furthermore, the left inner clamping ring and the right inner clamping ring, when combined, form a flared structure with a taper of 3 to 10 degrees.

[0012] Furthermore, the combination of the left inner clamping ring and the right inner clamping ring forms a spiral rotating leftward from the inside to the outside or a spiral rotating rightward from the inside to the outside at the top of the flared structure. The assembly tool with the spiral rotating leftward from the inside to the outside is suitable for an open sleeve with the left side overlapping the right side outside, and the assembly tool with the spiral rotating rightward from the inside to the outside is suitable for an open sleeve with the right side overlapping the left side outside.

[0013] Furthermore, the sum of the lengths of the left and right guide rails is greater than or equal to the width of the open sleeve.

[0014] Furthermore, the inner side of the left or right clamping ring is provided with an inner clamping ring step for abutting the tail end of the clamping ring on the opposite side.

[0015] Furthermore, the left and right clamping rings are 3D printed using PLA material.

[0016] Furthermore, the left and right clamping rings form a gripping structure that can be opened and closed at one end.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) It innovatively realizes the quick wrapping of cables or pipes with open sheaths, which greatly shortens the operation time, reduces the time spent on single-piece operations, and improves the overall assembly efficiency.

[0019] (2) The assembly tool has a reasonable overall structural design, mature manufacturing process, is easy to process and maintain, has good feasibility for mass production, and is conducive to large-scale promotion.

[0020] (3) It is easy to operate, reduces reliance on skilled workers, effectively reduces manpower input, reduces the labor intensity of workers, and improves work comfort and safety. Attached Figure Description

[0035] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention. Improvements and adjustments made by those skilled in the art based on the present invention in practical applications still fall within the scope of protection of the present invention.

[0036] To better illustrate the present invention, the following detailed description of the invention's implementation process is provided in conjunction with the accompanying drawings.

[0037] like Figures 1-6As shown, an assembly tool for cable installation open sleeve includes a left clamping ring 1, a right clamping ring 2, a pin 3, and a torsion spring 4. The torsion spring 4 is sleeved on the pin 3. The two ends of the pin 3 are hinged to the left clamping ring 1 and the right clamping ring 2. The left clamping ring 1 and the right clamping ring 2 form a clamping structure that can rotate and open around the axis of the pin 3, and have the structure of a hairpin gripper that can be opened and closed at one end.

[0038] The left clamping ring 1 includes a left handle portion and a left clamping portion. The left handle portion is covered with rubber or raised anti-slip ripples for anti-slip purposes. The left clamping portion is a double-layer guide structure, including a left inner clamping ring 1-1 and a left outer clamping ring 1-2. The cross-sections of the left inner clamping ring 1-1 and the left outer clamping ring 1-2 are both arc-shaped. The first end of the left outer clamping ring 1-2 is connected to the left handle portion, and its end is connected to the end of the left inner clamping ring 1-1. An opening is provided between the first end of the left inner clamping ring 1-1 and the first end of the left outer clamping ring 1-2. Therefore, an arc-shaped guide rail with one end open and the other end closed is formed between the left inner clamping ring 1-1 and the left outer clamping ring 1-2, which serves as the left guide rail for accommodating the open sleeve 6 along the circumference of the open sleeve 6.

[0039] The right clamping ring 2, correspondingly, also includes a right handle portion and a right clamping portion. The right handle portion, like the left handle portion, is covered with rubber or raised anti-slip ripples for anti-slip. The right clamping portion also has an inner and outer double-layer guide structure similar to the left clamping portion of the left clamping ring 1, including a right inner clamping ring 2-1 and a right outer clamping ring 2-2, both with arc-shaped cross-sections. The first end of the right outer clamping ring 2-2 is connected to the right handle portion, and its end is connected to the end of the right inner clamping ring 2-1. An opening is provided between the first end of the right inner clamping ring 2-1 and the first end of the right outer clamping ring 2-2, forming an arc-shaped guide rail with one end open and the other end closed between the right inner clamping ring 2-1 and the right outer clamping ring 2-2, serving as a right guide rail for accommodating the open sleeve 6 along the circumference of the open sleeve 6.

[0040] The left inner clamping ring 1-1 and the right inner clamping ring 2-1 are combined to form a flared structure with a taper of 3° to 10°. The inner side of the flared structure is used to accommodate and guide the cable 5 to pass through, and the outer side of the flared structure is used to guide the open sheath 6 to pass through the gap between the left inner clamping ring 1-1 and the left outer clamping ring 1-2, and the gap between the right inner clamping ring 2-1 and the right outer clamping ring 2-2.

[0041] At the same time, the combination of the left inner clamping ring 1-1 and the right inner clamping ring 2-1 forms two types at the top of the flared structure: a structure in which the spiral rotates to the left from the inside out and a structure in which the spiral rotates to the right from the inside out, which are mirror images of each other.

[0042] A spiral structure that rotates counterclockwise from the inside out, such as... Figure 1As shown, the end of the right clamping part of the right clamping ring 2 is located inside the left clamping ring 1. This arrangement of the assembly tool is suitable for situations where the left side of the open sheath 6 overlaps the outside of the right side; and the spiral rotates to the right from the inside out. Figure 1 The mirror image of the left clamping part of the left clamping ring 1 is positioned inside the right clamping ring 2. This configuration of the assembly tool is suitable for situations where the right side of the open sheath 6 overlaps the outside of the left side.

[0043] Therefore, depending on the different overlapping situations of the two sides of the open sheath 6 itself, the appropriate assembly tool with the correct spiral direction can be selected.

[0044] The sum of the lengths of the left and right guide rails is greater than or equal to the width of the open sleeve 6, so that the open sleeve 6 can be fully unfolded within the accommodating space formed by the left and right guide rails, avoiding the fact that it is still curled on the side at the opening in its natural state, which would affect the effect of the open sleeve 6 being fitted on the outside of the cable 5 and would not achieve the purpose of the open sleeve 6 being naturally and smoothly curled on the cable 5.

[0045] In addition, in order to stabilize the relative position of the left clamping ring 1 and the right clamping ring 2, an inner clamping ring step 7 is provided on the inner side of the left clamping ring 1 or the right clamping ring 2 to abut the tail end of the other clamping ring, so as to ensure that the relative position of the two clamping rings is fixed, thereby ensuring that the entire assembly tool is a stable structure when the cable 5 and the open sleeve 6 are inserted.

[0046] like Figure 1 As shown, an inner clamping ring step 7 is provided on the inner side of the left clamping ring 1 to abut the tail end of the right clamping ring 2, so as to ensure the stability between the left clamping ring 1 and the right clamping ring 2 during use.

[0047] The left clamping ring 1 and the right clamping ring 2 can be 3D printed from PLA material (i.e., polylactic acid biodegradable plastic) or made from other engineering materials with certain strength (such as carbon fiber, acrylonitrile-butadiene-styrene copolymer plastic). They can be set to different sizes and specifications as needed to fit the sleeve wrapping of cable conduits of different diameters.

[0048] The torsion spring 4 is made of stainless steel spring steel, such as 304 stainless steel, with a passivated surface, exhibiting corrosion resistance and fatigue resistance. It provides a continuous closing force to the left clamping ring 1 and right clamping ring 2, keeping the assembly tool closed when no external force is applied. When an external force is applied to the left clamping ring 1 and right clamping ring 2 to open them, the torsion spring 4 is compressed and stores energy, facilitating the assembly of the open sleeve 6 and cable 5 onto the assembly tool to ensure their positioning and secure assembly. The pin 3 has shoulders or retaining springs at both ends to prevent axial movement of the torsion spring 4.

[0049] This embodiment describes an assembly tool for cable installation open sleeves (with... Figure 1The working process of the flared, bell-shaped structure shown (taking a spiral structure that rotates from the inside out to the left as an example) is as follows:

[0050] (1) Based on the situation where the left side of the open sheath 6 overlaps the outside of the right side, select a sheath with the following characteristics: Figure 1 The flared structure shown is an assembly tool with a spiral structure that rotates to the left from the inside out.

[0051] (2) During operation, first pass the open sleeve 6 through the gap between the left inner clamping ring 1-1 and the left outer clamping ring 1-2 of the left guide rail, and the gap between the right inner clamping ring 2-1 and the right outer clamping ring 2-2. Then clamp the left clamping part and the right clamping part on the cable 5. Then manually wrap the end of the open sleeve 6 around the end of the cable 5. Then hold the open sleeve 6 that has been wrapped on the cable 5 with one hand, and use the other hand to hold the assembly tool to flatten the open sleeve 6 along the cable 5. The open sleeve 6 is first fully unfolded and flattened by the assembly tool, and then naturally curled on the outside of the cable 5 to complete the assembly of the cable 5 and the open sleeve 6.

[0052] In particular, for batch assembly operations of open sleeve 6 and cable 5, the assembly tool in this embodiment can achieve standardized assembly and improve assembly efficiency.

[0053] It should be noted that, in addition to wrapping open sleeves 6 around cables, the assembly tool of the present invention can also replace cables 5 with conduits, and can also include open sleeves on the outside of conduits.

[0054] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
