Description

Technical Field

[0001] This utility model relates to the technical field of spinning assembly disassembly tools, specifically to an assembly disassembly tool. Background Technology

[0002] In the polyester fiber spinning process, the spinning section requires a spinneret, which needs periodic maintenance and replacement. During these maintenance periods, the spinneret is typically disassembled using ordinary tools. However, these tools only have locking teeth. Normally, the spinneret is held in place by its groove, and the tool is unloaded by rotating the mounting nut and relying on its own weight. However, during disassembly, components that are difficult to remove with ordinary tools often arise. When components cannot be removed by their own weight, ordinary tools become unusable, leading to significant inconvenience. Summary of the Invention

[0003] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide a component disassembly tool that can disassemble components that are difficult to disassemble in the spinning section, thereby solving the problem that abnormal components cannot be disassembled by traditional disassembly tools.

[0004] To address the aforementioned technical problems, the objective of this application is achieved through the following technical solution:

[0005] A component disassembly tool is characterized by comprising a steel strip, a hose clamp at one end of the steel strip, and a fastening bolt on the hose clamp. One end of the steel strip passes through the hose clamp to form a retaining ring. The fastening bolt is vertically positioned. A first pull rod is provided at the lower end of the fastening bolt. A second pull rod is provided on the outer side of the retaining ring. The fastening bolt is driven to rotate by the first pull rod. After the exposed end of the wire-exiting component to be disassembled is fastened by the retaining ring, it is pulled downwards and removed by the first pull rod and the second pull rod.

[0006] Preferably, the inner ring of the retaining ring is provided with a plurality of downwardly inclined barbs.

[0007] Preferably, both the first pull rod and the second pull rod have a pull ring at their lower ends.

[0008] Preferably, a crossbar is provided between the first pull rod and the second pull rod, and a collar is provided at both ends of the crossbar, with a locking nut on the collar.

[0009] Preferably, a limiting ring is provided in the middle of the crossbar, a locking nut is provided on one side of the limiting ring, and a detachable auxiliary material picking mechanism is provided inside the limiting ring. The upper end of the auxiliary material picking mechanism is fixed in the inner hole of the wire outlet of the wire outlet assembly to be disassembled. The wire outlet assembly to be disassembled can be pulled down for disassembly after the inner hole is locked by the auxiliary material picking mechanism.

[0010] Preferably, the auxiliary material handling mechanism includes a T-shaped pull rod, threaded sections symmetrically arranged at both ends of the T-shaped pull rod, and a push pin threadedly connected to the two threaded sections. The outer side of the connecting end of the push pin has a hexagonal structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] When fixing the components, steel straps are used for ring clamping, which provides sufficient contact and force-bearing surfaces for disassembly. This effectively avoids the problem that ordinary disassembly tools cannot pull downwards, allowing the components to be removed without relying on their own weight. This solves the problem that abnormal components cannot be disassembled using traditional disassembly tools, making it simpler and more convenient to disassemble components that are difficult to disassemble in the spinning section.

[0018] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0020] The terms "first," "second," etc., used in this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, without limiting the number of objects; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0021] Example 1:

[0022] like Figure 1 As shown, a component disassembly tool includes a steel strip 4, a hose clamp 6 at one end of the steel strip 4, and a fastening bolt 5 on the hose clamp 6. One end of the steel strip 4 passes through the hose clamp 6 to form a retaining ring. The fastening bolt 5 is vertically arranged, and a first pull rod 7 is provided at the lower end of the fastening bolt 5. A second pull rod 3 is also provided on the outside of the retaining ring. The fastening bolt 5 is driven to rotate by the first pull rod 7. After the exposed end of the wire-exiting component to be disassembled is fastened by the retaining ring, it is pulled down and removed by the first pull rod 7 and the second pull rod 3.

[0023] In practical use, the diameter of the retaining ring is larger than the outer diameter of the component. When the component needs to be disassembled, the retaining ring is placed around the component by holding the first pull rod 7 and the second pull rod 3. Then, by rotating the first pull rod 7, the retaining ring is reduced to tighten around the outer wall of the component. The operator then pulls the component out of the spinning equipment using the two pull rods. When fixing the component, a steel band 4 is used for ring clamping, which provides sufficient contact and force-bearing surface during disassembly. This effectively avoids the problem that ordinary disassembly tools cannot pull downwards, allowing the component to be removed without relying on its own weight. This solves the problem of abnormal components that cannot be disassembled using traditional disassembly tools, making the disassembly of components that are difficult to disassemble in the spinning section simpler and more convenient.

[0024] Further improvements include, for example Figure 2 As shown, the inner ring of the retaining ring is provided with a plurality of downwardly inclined barbs 10.

[0025] The barbs 10 are conical or triangular downward-sloping protrusions. When the clamping ring clamps the component, the barbs 10 contact and lock with the outer side of the component. The barbs 10 contact the component and can better lock the component when pulling downward, preventing it from falling off during the pull.

[0026] A further improvement is that a pull ring 1 is provided at the lower end of both the first pull rod 7 and the second pull rod 3.

[0027] When pulling the component downwards, it is more convenient to pull it through the pull ring 1, and the operation makes the force more direct.

[0028] A further improvement is made by providing a crossbar 2 between the first pull rod 7 and the second pull rod 3, with a collar 9 at each end of the crossbar 2, and a locking nut 8 on the collar 9.

[0029] A crossbar 2 is installed between the first pull rod 7 and the second pull rod 3. The crossbar 2 can fix the relative position of the first pull rod 7 and the second pull rod 3 to avoid wobbling. At the same time, the two ends of the crossbar 2 are connected to the first pull rod 7 and the second pull rod 3 by a combination of collar 9 and locking nut 8, which can facilitate the vertical movement of the crossbar 2. When it is moved into place, it can be easily fixed by tightening the locking nut 8. The second pull rod 3 and the steel belt 4 can be connected and fixed by a hinge or universal joint shaft. When the ring is extended or retracted, it can be adjusted synchronously to a certain extent to prevent the second pull rod 3 and the pull ring 1 from jamming.

[0030] Example 2:

[0031] Further improvements include, for example Figure 3 As shown, a limiting ring 12 is provided in the middle of the crossbar 2, and a locking nut 8 is provided on one side of the limiting ring 12. A detachable auxiliary material picking mechanism 11 is provided inside the limiting ring 12. The upper end of the auxiliary material picking mechanism 11 is fixed in the inner hole of the wire outlet of the wire outlet assembly to be disassembled. The wire outlet assembly to be disassembled can be pulled down to disassemble after the inner hole is locked by the auxiliary material picking mechanism 11.

[0032] When removing materials from the wire feeding components to be disassembled, some components have particularly high rigidity. In this case, simply using the steel belt 4 to pull them with clamps can easily lead to problems with timely removal due to the limitations of the force-bearing area and the pull rod. However, by adding the auxiliary material removal mechanism 11, not only can the components be positioned internally and externally, but they can also be pulled by force from both inside and outside simultaneously, thus making the disassembly of the components more effective.

[0033] Further improvements include, for example Figure 4As shown, the auxiliary material handling mechanism 11 includes a T-shaped pull rod 13, threaded sections 15 symmetrically arranged at both ends of the T-shaped pull rod 13, and a push pin 14 threadedly connected to the two threaded sections 15. The outer side of the connecting end of the push pin 14 has a hexagonal structure.

[0034] The crossbar 2 of the T-shaped pull rod 13 has threaded sections 15 at both ends, while the ejector pin 14 is a tapered structure with threaded holes. After the ejector pin 14 is threaded onto the threaded section 15, relative extension and retraction can be achieved by rotating the ejector pin 14 to adapt to different inner diameter requirements. The outer side of the connecting end of the ejector pin 14 has a hexagonal structure, which facilitates rotation by a wrench. When fixing the inner hole of the component through the auxiliary material handling mechanism 11, the T-shaped pull rod 13 is first inserted into the limiting ring 12, and then the outer ring of the component is tightened by the steel strip 4. Then, the T-shaped pull rod 13 is pushed upward into the inner hole of the component and then fixed by the locking nut 8. Finally, the ejector pins 14 at both ends are rotated by the wrench until the ejector pins 14 are pressed against the inner hole of the component. Finally, the first pull rod 7, the second pull rod 3 and the T-shaped pull rod 13 are pulled downward synchronously. A pull rope or a detachable pull ring 1 can also be installed at the lower end of the T-shaped pull rod 13 for easier pulling during disassembly.

[0035] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
