Description

Technical Field

[0001] This utility model belongs to the field of frame stranding machines, specifically a wire coil clamping device for frame stranding machines. Background Technology

[0002] In the production process of wire stranding machines, the wire spool clamping device is a core component that ensures wire quality and production efficiency. Its performance directly determines the stability of the wire spool rotation and the accuracy of wire winding.

[0003] In existing technologies, most wire reel clamping devices for wire stranding machines employ a mechanical contact structure, relying on mechanical bearings to fix and support the clamping sleeve, facilitating the rotation of the clamping sleeve and the pay-off reel. However, during long-term operation, friction between mechanical parts leads to mechanical wear of the bearings, requiring frequent replacement of parts, resulting in high equipment maintenance costs and significantly shortening the device's lifespan. Furthermore, frequent addition of lubricant can cause lubricant overflow or leakage, contaminating the cables. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a frame stranding machine reel clamping device, which solves the problem that most existing frame stranding machine reel clamping devices rely on mechanical bearings to fix and support the clamping sleeve, and that mechanical bearings will be damaged due to mechanical wear, affecting their service life.

[0005] A wire reel clamping device for a frame stranding machine includes a wire feeding reel with variable diameter slots at both ends. Each end of the wire feeding reel is provided with a clamping sleeve. A connecting component is provided on the outside of the clamping sleeve. A magnetic levitation component is provided between the clamping sleeve and the connecting component.

[0006] The magnetic levitation component includes several coaxially arranged magnetic rings 1 and 2, with magnetic rings 1 and 2 spaced apart. The inner diameter of magnetic ring 1 is larger than the outer diameter of magnetic ring 2.

[0007] Preferably, the clamping sleeve includes a circular boss that is adapted to the variable diameter slot, a positioning sleeve is provided on the circular boss, a connecting post is provided on the end of the positioning sleeve away from the wire feeding reel, and a plurality of connecting holes are provided on the connecting post.

[0008] Preferably, the connecting post is provided with a plurality of annular grooves, and the magnetic ring II is fixedly disposed in the corresponding annular groove.

[0009] Preferably, the connecting assembly includes two mating sleeves arranged opposite each other. A mounting base is provided on the end of the mating sleeve away from the wire feeding reel. Bolt holes are provided on the sides of the two mating sleeves that are close to each other, and bolts are provided in the bolt holes.

[0010] Preferably, the docking sleeve is provided with a plurality of annular grooves, and the magnetic ring is fixedly disposed in the corresponding annular groove.

[0011] Preferably, both magnetic ring one and magnetic ring two are composed of a number of permanent magnets.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model uses a ring-shaped permanent magnet array composed of magnetic ring one and magnetic ring two in the magnetic levitation component to make the clamping sleeve and the connecting component suspend in a suspended state by utilizing the principle of like poles repulsion. This eliminates the mechanical friction when the pay-off reel rotates. Compared with the traditional mechanical clamping method, it greatly reduces component wear, extends the service life of the device, and avoids the need for lubrication, thus eliminating the pollution of the cable by lubricating oil.

[0014] 2. This utility model can automatically compensate for changes in clamping force caused by vibration and other factors during operation through the magnetic levitation component. Combined with the stable clamping of the connecting component, it can keep the coil stable when rotating at high speed, effectively improving the accuracy and production quality of cable winding and reducing the defect rate.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] As attached Figure 1 To be continued Figure 3 As shown:

[0022] This utility model provides a wire reel clamping device for a frame stranding machine, including a wire feeding reel 1, with a clamping sleeve 2, a connecting component 3, and a magnetic levitation component 4 respectively provided at both ends, so as to achieve stable clamping of wire reels of different specifications and ensure the smooth operation of the wire feeding process of the frame stranding machine.

[0023] As attached Figure 1 To be continued Figure 2 As shown: The pay-off reel 1, with variable-diameter slots at both ends, is the core load-bearing component of the entire clamping device, used for mounting the reel. The variable-diameter slot design can accommodate reels with different center hole diameters, improving the versatility of the device. The pay-off reel 1 is mounted on the rotating shaft of the frame stranding machine via bearings, ensuring its flexible rotation. This mounting method allows the pay-off reel 1 to rotate smoothly under the power drive of the frame stranding machine, providing a stable foundation for cable pay-off.

[0024] As attached Figure 2 To be continued Figure 3 As shown: The clamping sleeve 2 includes a circular boss 201 adapted to the variable diameter slot. A positioning sleeve 202 is provided on the circular boss 201. A connecting post 203 is provided at the end of the positioning sleeve 202 away from the pay-off reel 1, and a connecting hole 5 is provided on the connecting post 203. The circular boss 201 is tightly embedded in the variable diameter slot of the pay-off reel 1 and fixed by interference fit or key connection to ensure a reliable connection between the clamping sleeve 2 and the pay-off reel 1. The positioning sleeve 202 is used for preliminary positioning of the reel to ensure the accuracy of the reel installation. The clamping device at one end is connected to the flange of the drive device through the connecting hole 5 to receive power to drive the pay-off reel 1 to rotate and pay off the wire; the clamping device at the other end is connected to the lifting bracket or telescopic cylinder through the connecting hole 5 to realize the lifting or telescopic adjustment of the pay-off reel 1, which facilitates the loading and unloading of the reel and meets the needs of different production scenarios.

[0025] As attached Figure 2 To be continued Figure 3 As shown, the connecting assembly 3 consists of two opposing mating sleeves 301. A mounting base 302 is provided at the end of each mating sleeve 301 furthest from the pay-off reel 1. Bolt holes are provided on the sides of the two mating sleeves 301 closest to each other, and bolts 303 are installed in these holes. The mating sleeves 301 are fixedly connected to the magnetic ring 401 in the magnetic levitation assembly 4 via annular grooves. The mounting base 302 is used to connect to external equipment (such as a lifting bracket or telescopic cylinder). By tightening the bolts 303, the two mating sleeves 301 can be tightly fixed, thereby forming a stable clamping force on the clamping sleeve 2 and the pay-off reel 1. This connection method facilitates installation and disassembly, and the clamping degree of the mating sleeves 301 can be adjusted according to the reel specifications, enhancing the adaptability of the device.

[0026] As attached Figure 2 To be continued Figure 3As shown, the magnetic levitation assembly 4 includes several coaxially arranged and spaced magnetic rings 401 and 402. The inner diameter of magnetic ring 401 is larger than the outer diameter of magnetic ring 402, and both are composed of several permanent magnets. Magnetic ring 402 is fixedly installed in the annular groove of the connecting post 203 of the clamping sleeve 2, and magnetic ring 401 is fixedly installed in the annular groove of the mating clamp 301 of the connecting assembly 3. The magnetic levitation assembly 4 utilizes the principle of like poles repulsion of permanent magnets to generate magnetic levitation force between the clamping sleeve 2 and the connecting assembly 3, keeping them in a suspended state while limiting the axial displacement of the clamping sleeve 2. This magnetic levitation structure can effectively reduce direct contact and friction between the clamping sleeve 2 and the connecting assembly 3, reducing wear. At the same time, during the operation of the frame winch, the magnetic levitation force can automatically compensate for changes in clamping force caused by vibration and other factors, maintaining a stable clamping effect.

[0027] Working principle: Install magnetic ring 2 (402) into the annular groove of the connecting post 203 of clamping sleeve 2, ensuring a secure installation. Align the annular groove on the mating sleeve 301 with magnetic ring 401, fixing magnetic ring 401 within the mating sleeve 301. Place the two mating sleeves 301 opposite each other on the outside of clamping sleeve 2, insert bolts 303 through the bolt holes, and initially tighten the bolts 303 to allow the mating sleeves 301 to initially clamp the clamping sleeve 2.

[0028] One clamping device is connected to the drive device through the connecting hole 5 on the connecting column 203 to ensure a stable connection and effective power transmission. The other clamping device is connected to the lifting bracket through the mounting base 302. The wire feeding reel 1 is inserted into the clamping sleeve 2 installed on the lifting bracket. The height of the lifting bracket is adjusted so that the other end of the wire feeding reel 1 is close to the other clamping device. The wire feeding reel is fixed by the squeezing of the two clamping devices.

[0029] The cable winch is started, and the drive unit rotates the pay-off reel 1 to begin cable pay-off operations. During operation, the magnetic levitation component 4 activates, and the magnetic force generated by the annular permanent magnet array suspends the pay-off reel 1. A non-contact state is established between the clamping sleeve 2 and the connecting component 3, allowing for frictionless rotation supported by magnetic force. During the winch's operation, the pay-off reel 1 rotates together with the clamping sleeve 2. Since there is no mechanical friction, lubrication is unnecessary, preventing contamination and reducing maintenance costs and workload.
