Description

Technical Field

[0001] This application relates to the technical field of bearing disassembly and assembly tools, and in particular to a bearing disassembly and assembly tool for an integrated spinning wheel yarn guide assembly. Background Technology

[0002] In the traditional maintenance model, maintenance of the cable guide assembly usually requires the replacement of the entire integrated component, which integrates core components such as bearings, cable guide ring housings and sealing plastic parts. From a cost control perspective, the maintenance solution of replacing the bearings separately is obviously more economical. However, due to the limitations of the existing structural design, this optimized solution is difficult to implement in practice.

[0003] Currently, most integrated cable guide assemblies on the market are brand-specific parts and fall into the category of non-standard parts. This characteristic means that users must order them through the brand's official channels when performing repairs. This not only makes the procurement process cumbersome but also results in a long waiting period, which seriously affects the repair efficiency and user experience of the equipment.

[0004] From a manufacturing perspective, existing integrated cable guide assemblies are generally assembled using sealing and pressing or adhesive sealing processes. While this process design ensures the sealing and stability of the equipment, it also brings the problem of difficult disassembly. If it is forcibly disassembled, it is very easy to damage the cable guide ring shell or sealing plastic parts, which will lead to the scrapping of the entire main component.

[0005] In actual maintenance scenarios, when a bearing experiences non-functional failures such as abnormal noise, even though components such as the guide ring housing and sealing plastic parts still have good performance, due to the limitations of traditional maintenance solutions, these functional parts are often replaced along with the bearing and ultimately treated as waste, resulting in serious material waste and resource depletion. Utility Model Content

[0006] To address the problems mentioned in the background art, this application provides a bearing disassembly and assembly tool for an integrated spinning wheel yarn guide assembly.

[0007] This application provides a bearing disassembly and assembly tool for an integrated yarn guide assembly of a spinning wheel, which adopts the following technical solution: A bearing disassembly and assembly tool for an integrated yarn guide assembly of a spinning wheel includes a stainless steel positioning seat, an ejector screw, and a circular reset pressure plate. The circular reset pressure plate is located at the top of the ejector screw. The top of the stainless steel positioning seat is provided with a slot, and the interior of the slot is threadedly connected to the surface of the ejector screw. An ejector rod is integrally cast at the top of the ejector screw.

[0008] Optionally, a rotating rod is integrally cast on the top of the outer side of the ejector rod. The ejector rod and the rotating rod have a cross-shaped structure, which facilitates manual rotation to apply torque.

[0009] Optionally, the tolerance between the inner wall of the slot of the stainless steel positioning seat and the outer diameter of the wire guide assembly is controlled within ±

[0010] Radial displacement is limited by 0.1mm. A customized slot precisely engages with the outer edge of the wire assembly to limit radial displacement.

[0011] Optionally, the ejector screw, ejector rod, and rotating rod are made of 304 stainless steel. The outer diameter of the ejector rod is 1mm larger than the inner diameter of the bearing. By manually rotating it, an axial thrust of >200N is generated, and the old bearing is ejected without impact load.

[0012] Optionally, the diameter of the circular reset pressure plate and the inner diameter of the sealing plastic part are controlled within ±0.05mm, and a bearing is press-fitted into the bottom of the ejector rod to achieve a reset accuracy of ±0.05mm.

[0013] Optionally, the circular reset plate is made of brass with polished edges, utilizing the flexibility of brass to avoid damaging the plastic seal during pressing.

[0014] Optionally, the stainless steel positioning seat is a rigid integrated structure, used to prevent the wire guide assembly from shifting under force during disassembly and damaging the wire guide ring housing or sealing plastic parts.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] 1. This utility model, by setting up components such as a stainless steel positioning seat and an ejector screw, utilizes the cooperation between the slot of the stainless steel positioning seat and the ejector screw to allow the stainless steel positioning seat to precisely engage with the outer edge of the wire guide assembly to limit radial displacement. The ejector screw, through its ejector rod, presses against the inner ring of the bearing. The outer diameter of the ejector rod is slightly larger than the inner diameter of the bearing but smaller than the inner diameter of the plastic part. This effectively presses against the inner ring of the bearing without contacting the plastic part of the wire guide ring, thus achieving the effect of this device conveniently ejecting old bearings without impact load.

[0017] 2. This utility model, by setting up components such as an ejector screw and a circular reset pressure plate, and through the linkage between the ejector screw and the circular reset pressure plate, enables the circular reset pressure plate to press and reset the bearing by controlling the tolerance of the inner diameter of the sealing plastic part and the flexibility of brass. Thus, this device can ensure a reset accuracy of ±0.05mm through precise linkage press-fitting and avoid damage to the plastic seal. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] This application discloses a bearing disassembly and assembly tool for an integrated spinning wheel yarn guide assembly.

[0027] Please see Figures 1 to 6 A bearing disassembly and assembly tool for an integrated spinning wheel yarn guide assembly includes a stainless steel positioning seat 1, an ejector screw 2, and a circular reset pressure plate 3. The circular reset pressure plate 3 is located on top of the ejector screw 2. The top of the stainless steel positioning seat 1 has a slot 4, the inside of which is threaded to the surface of the ejector screw 2. An ejector rod 5 is integrally cast on the top of the ejector screw 2. The slot 4 of the stainless steel positioning seat 1 can precisely engage with the outer edge of the yarn guide assembly, limiting its radial displacement and preventing damage to the yarn guide ring housing or sealing plastic parts during disassembly due to force deviation. The bottom of the ejector rod 5 is adapted to the inner ring of the bearing. The circular reset pressure plate 3 cooperates with the bottom of the ejector rod 5 to achieve press-fit reset of the bearing, yarn guide ring housing, and sealing plastic parts. A rotating rod 7 is integrally cast on the top of the outer side of the ejector rod 5. The ejector rod 5 and the rotating rod 7 have a cross-shaped structure, which facilitates manual rotation to apply torque. The cross-shaped structure of the ejector rod 5 and the rotating rod 7 facilitates manual rotation to apply torque, allowing users to easily operate the ejector screw 2 to eject the old bearing.

[0028] Please see Figures 1 to 6The tolerance between the inner wall of the slot 4 of the stainless steel positioning seat 1 and the outer diameter of the wire guide assembly is controlled within ±0.1mm, effectively limiting the displacement of the wire guide assembly. The customized slot 4 precisely engages with the outer edge of the wire guide assembly, limiting radial displacement. The inner wall of the slot 4 of the stainless steel positioning seat 4 and the outer diameter of the wire guide assembly are controlled within ±0.1mm. The customized slot 4 precisely engages with the outer edge of the wire guide assembly, achieving axial alignment and limiting the radial displacement of the wire guide assembly. This ensures stability during disassembly, prevents the wire guide assembly from shifting under force, and allows for the ejection screw 2 to... The ejector rod 5 and the rotating rod 7 are made of 304 stainless steel. The outer diameter of the ejector rod 5 is 1mm larger than the inner diameter of the bearing. By manually rotating it, an axial thrust of >200N is generated, which can eject the old bearing without impact load. The ejector screw 2, ejector rod 5 and rotating rod 7 are made of 304 stainless steel to ensure the strength and durability of the tool. The outer diameter of the ejector rod 5 is 1mm larger than the inner diameter of the bearing. By manually rotating it, an axial thrust of >200N is generated, which can eject the old bearing without impact load and avoid damage to the bearing raceway and other parts of the wiring assembly.

[0029] Please see Figures 1 to 6 The diameter of the circular reset pressure plate 3 and the inner diameter of the sealing plastic part are controlled within ±0.05mm. It is linked with the ejector rod 5 to press the bearing, and the reset accuracy reaches ±0.05mm. This ensures that the bearing is pressed in the correct position and that the axial clearance meets the original factory standard. The circular reset pressure plate 3 is made of brass and has polished edges. The flexibility of brass is used to avoid damage to the plastic seal during pressing and to protect the integrity of the sealing plastic part. The stainless steel positioning seat 1 is a rigid integrated structure. It is used to prevent the wire guide assembly from shifting under force during disassembly and damaging the wire guide ring shell or sealing plastic part. The rigid integrated structure of the stainless steel positioning seat 1 can withstand the force during disassembly and prevent the wire guide assembly from shifting under force, thereby protecting the wire guide ring shell or sealing plastic part from damage.

[0030] The implementation principle of the bearing disassembly and assembly tool for an integrated spinning wheel yarn guide assembly in this application embodiment is as follows: When in use, the first step is to enter the positioning and fixing stage. The customized slot 4 of the stainless steel positioning seat 1 is aligned with the outer edge of the yarn guide assembly. The tolerance design of ±0.1mm between the inner wall of the slot 4 and the outer diameter of the yarn guide assembly is used to achieve precise engagement, thereby limiting the radial displacement of the yarn guide assembly and ensuring axial alignment. This rigid integrated stainless steel positioning seat 1 can withstand the force in subsequent operations, avoiding the yarn guide assembly from being deflected by force and damaging the yarn guide ring shell or sealing plastic parts, thus providing a stable foundation for the entire disassembly and assembly process.

[0031] Next, the bearing disassembly stage begins. The ejector rod 5 at the top of the ejector screw 2 forms a cross shape with the rotating rod 7. The user can manually rotate the rod to apply torque, driving the ejector screw 2 to move downwards. The screw 2 is made of 304 stainless steel. The outer diameter of the ejector rod 5 is about 1mm larger than the inner diameter of the bearing inner ring under the action of the ejector screw 2, which can accurately fit the bearing inner ring. As the screw rotates, it can generate an axial thrust of more than 200N, gradually ejecting the old bearing without impact load. This design avoids the bearing raceway scratches or seal plastic parts damage that may be caused by traditional hammering methods. Tests have shown that the main body of the assembly is 100% undamaged.

[0032] After removing the old bearing, the bearing replacement and reassembly stage begins. First, a new bearing of the same specifications is placed into the wire guide assembly. Then, the wire guide ring housing is inverted into the slot 4. The sealing plastic part is placed on top of the wire guide ring housing, and then the circular resetting pressure plate 3 is placed on top of it. Next, the ejector screw 2 is inserted into the slot 4. The ejector screw 2 is easily rotated downwards by the cross-shaped structure formed by the ejector rod 5 and the rotating rod 7. The downward movement of the ejector screw 2 causes the ejector rod 5 to move downwards, pushing the circular resetting pressure plate 3 for pressing. The tolerance between the diameter of the circular resetting pressure plate 3 and the inner diameter of the sealing plastic part is ±0.05mm. Plate 3 can push the bearing and sealing plastic parts into their original positions synchronously, with a reset accuracy of ±0.05mm, ensuring that the axial clearance meets the original factory standard. The circular reset pressure plate 3 is made of brass and has been polished at the edges. Utilizing the flexibility of brass, it can avoid scratching the plastic seals during pressing. The entire process is achieved through a three-stage linkage mechanism of "slot 4 positioning - axial ejection - circular reset pressure plate 3 reset", which breaks through the technical barrier of the integrated wiring assembly being non-disassembly, realizes the non-destructive replacement and precise reset of the bearing, and enables users to complete the bearing replacement independently, significantly reducing maintenance costs and reducing resource waste.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
