[0002] Amid the rapid development of fiber-optic communication technology, fiber optic tubing, as a core component, has a quality that directly impacts the performance and stability of the entire communication system. Fiber optic tubing primarily consists of a fixed outer casing and the optical fibers within. The spinning and shaping of the fiber tips is a critical process for ensuring fiber connection performance. While existing single-point spinning technology can achieve this shaping task to a certain extent, its limitations are becoming increasingly apparent in practical applications.

[0003] Existing single-point spinning technology, when shaping the fiber tip, relies solely on a single spinning point to apply pressure to the fiber tip, resulting in an inefficient shaping process. This inefficiency has become a bottleneck in the production of large quantities of fiber optic tubing. Furthermore, the single-point spinning process places extreme local pressure at the stress point, and prolonged, high-intensity spinning can easily cause deformation at the fiber extrusion point. This not only affects the shaping effect of the fiber tip but also increases maintenance costs.

DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention. Example

[0027] This embodiment provides a dual-servo high-precision pipe spinning device, which is used to spin and shape the head of the optical fiber 520 of the pipe 500 to be processed, wherein, see Figure 1 As shown, the pipe 500 to be processed includes a fixed housing 510 with a relatively large diameter and an optical fiber 520 inside the housing.

[0028] See also Figure 2 As shown, the dual-servo high-precision pipe spinning equipment in this embodiment includes:

[0029] The rotary clamping mechanism 100 includes a driving mechanism 120 and a clamping member 130. The clamping member 130 is connected to the working end of the driving mechanism 120 and rotates around a rotation centerline 1001 by the driving mechanism 120. The pipe 500 to be processed is inserted into the clamping member 130 and rotates synchronously with the clamping member 130.

[0030] The squeezing mechanism 200 is spaced apart from the rotating clamping mechanism 100 along the first direction X. The head of the optical fiber 520 of the pipe 500 to be processed is arranged toward the squeezing mechanism 200. The squeezing mechanism 200 includes:

[0031] A lifting assembly 210 includes a first lifting module 212, a first slide 213, and two lifting wheels 214. The first lifting module 212 moves up and down along the height direction of the extrusion mechanism 200. The first slide 213 is slidably connected to the first lifting module 212. The two lifting wheels 214 are spaced apart on the first slide 213 along the second direction Y.

[0032] The extrusion assembly 220 includes a second lifting module 221, a second slide 222 and an extrusion wheel 223. The second lifting module 221 is arranged above the first lifting module 212 and extends in the same direction as the first lifting module 212. The second slide 222 is slidably connected to the second lifting module 221. The extrusion wheel 223 is arranged on the second slide 222, and in the second direction Y, the extrusion wheel 223 is located between the two lifting wheels 214. The head of the optical fiber 520 is located between the extrusion wheel 223 and the two lifting wheels 214.

[0033] The dual-servo high-precision pipe spinning equipment described in this embodiment clamps and fixes the pipe 500 to be processed by the rotary clamping mechanism 100 and provides driving force for its rotation. At the same time, the head of the optical fiber 520 is squeezed at three points from three directions by the squeezing mechanism 200, thereby making the optical fiber 520 uniformly stressed in the circumferential direction, thereby fundamentally avoiding the influence of the single-point spinning technology in the conventional processing process at this stage on the shaping effect of the head of the optical fiber 520. In addition, the rotary clamping mechanism 100 and the squeezing mechanism 200 in this application are highly coordinated, thereby significantly improving the processing efficiency. Compared with the conventional processing technology at this stage, this application has the advantages of simple operation, high processing precision, fast processing efficiency, good controllability and a wide range of applications.

[0034] It is worth noting that, for ease of expression, this embodiment defines the length direction of the dual-servo high-precision pipe spinning equipment as the first direction X, the width direction of the equipment as the second direction Y, and the height direction of the equipment as the third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are arranged perpendicular to each other in pairs, and the first direction X and the second direction Y are located in the same plane.

[0035] See also Figure 2 As shown, the present apparatus is mounted on a base plate 400 for easy assembly or transfer. It is preferably a rectangular tube extending in the same direction as the pipe 500 to be processed. The extrusion mechanism 200 is disposed at one end of the base plate 400 in the longitudinal direction, spaced apart from the rotary clamping mechanism 100. The rotary clamping mechanism 100 is used to secure the pipe 500 to be processed and to drive the pipe 500 to rotate, thereby achieving a uniform shaping effect through circumferential compression and clamping. Correspondingly, the extrusion mechanism 200 compresses the head of the optical fiber 520 to be processed through the cooperation between the lifting wheel 214 and the extrusion wheel 223. Furthermore, in this embodiment, the rotation centerline 1001 coincides with the central axis of the pipe 500 to be processed.

[0036] See also Figure 3As shown, the rotary clamping mechanism 100 in this embodiment also includes an assembly frame 110, which is mounted on a base plate 400. The drive mechanism 120 and the clamping member 130 are respectively rotatably connected to the assembly frame 110. Furthermore, the drive mechanism 120 includes a rotary driver 121, a transmission belt 122, and a drive wheel 123. The rotary driver 121 is connected to one side of the assembly frame 110. The drive wheel 123 is inserted into the assembly frame 110. The side facing the extrusion mechanism 200 is connected to the clamping member 130, and the other side is provided with a threaded structure. The two ends of the transmission belt 122 are respectively sleeved on the working end of the rotary driver 121 and the threaded surface of the drive wheel 123. Specifically, the working end of the rotary driver 121 in this embodiment is also configured with a threaded structure, thereby increasing the friction between it and the transmission belt, thereby preventing relative slippage between the two.

[0037] To achieve clamping and fixing of the optical fiber 520, the clamping member 130 includes a clamping barrel 131 and at least two clamping blocks 132. The clamping barrel 131 is connected to the driving mechanism 120. At least two clamping blocks 132 are disposed within the clamping barrel 131 and move relative to each other. Each clamping block 132 includes a contoured groove that matches the outer surface shape of the optical fiber 520 to be processed, thereby fixing the optical fiber 520 to be processed. In this embodiment, two clamping blocks 132 are specifically provided, and the two clamping blocks 132 are controlled by a pneumatic structure to achieve relative opening and closing movement. In different embodiments, other numbers of clamping blocks 132 may be provided based on actual usage requirements. The clamping blocks 132 may also be replaced with contoured grooves that match the curvature of the optical fiber 520 to be processed. This is not specifically limited in the present invention.

[0038] See also Figure 4 and Figure 5As shown, the lifting assembly 210 in this embodiment is disposed below the extrusion assembly 220. It is used to support the optical fiber 520 to be processed and is also used to cooperate with the extrusion assembly 220 to achieve extrusion and shaping of the optical fiber 520. Furthermore, the lifting assembly 210 in this embodiment also includes a base 211, and the first lifting module 212 is connected to the base 211. The lifting assembly 210 also includes at least one guide column 215 and at least one reset member 216. The guide column 215 extends along the height direction of the lifting assembly 210, one end of which is fixed to the base plate 400 and the other end is connected to the first slide 213. The reset member 216 is sleeved on the guide column 215 in a one-to-one correspondence. When the optical fiber 520 to be processed is supported by the lifting assembly 210, the reset member 216 is in a compressed state to provide a lifting driving force for the first slide 213. Specifically, this embodiment includes two guide columns 215 and two reset members 216, thereby improving the lifting stability of the lifting assembly 210. The reset member 216 in this embodiment is preferably a spring. In different embodiments, the reset member 216 can also be configured as an elastic rubber, spring sheet, etc. that can achieve automatic lifting structures. The present utility model does not impose specific restrictions on this.

[0039] See also Figure 3 and Figure 4 As shown, the extrusion assembly 220 in this embodiment also includes a pushing driver 224, which is arranged at the top of the first lifting module 212, and its working end is connected to the second slide 222. When it pushes the extrusion wheel 223 to move downward, it can realize synchronous extrusion of the head of the optical fiber 520 from the relative direction with the lifting assembly 210. Based on this, it cooperates with the rotating clamping mechanism 100 to realize circumferential uniform shaping of the head of the optical fiber 520.

[0040] See also Figure 5As shown, in actual use, in order to make the present application applicable to pipe fittings 500 to be processed of different lengths, an adjustment mechanism 300 is further provided in this embodiment, wherein the adjustment mechanism 300 includes a moving component 320 and a guide rail 310, wherein the guide rail 310 extends along a first direction X, and the moving component 320 is slidably connected to the guide rail 310, and the moving component 320 is respectively arranged on two sides opposite to the extrusion mechanism 200 in the first direction X, and the pipe fitting 500 to be processed is supported in the moving component 320. Furthermore, the moving assembly 320 includes a support frame 321, at least two support wheels 322, and a limiting wheel 323. The top of the support frame 321 is provided with a downwardly recessed receiving groove 326, in which the pipe 500 to be processed is supported. The support wheels 322 are arranged around the receiving groove 326. The limiting wheel 323 is arranged above the receiving groove 326 and moves toward / away from the receiving groove 326 to abut / release the pipe 500 to be processed. Specifically, the moving assembly 320 also includes a flip bracket 324 and a handle 325. The flip bracket 324 is provided at the top of the support frame 321, is connected to the limiting wheel 323, and drives the limiting wheel 323 to move toward / away from the receiving groove 326. The handle 325 is connected to the flip bracket 324. Based on this, the moving component 320 can adapt to pipes 500 to be processed of different lengths through the guide rail 310, and the flip bracket 324 can enable the moving component 320 to adapt to pipes 500 to be processed of different diameters, thereby expanding the scope of application and flexibility of use of this application.

[0041] This embodiment includes a control system, and the rotating clamping mechanism 100 and the extrusion mechanism 200 are respectively connected to the control system.
