Description

Technical Field

[0001] This utility model relates to the field of coaxial cable machining technology, and in particular to a tension adaptive adjustment mechanism in coaxial cable machining. Background Technology

[0002] Coaxial cable is a high-frequency transmission line consisting of an inner conductor, an insulating medium, an outer conductor, and an outer sheath. It is widely used in fields such as communications, radio frequency, and radar. Its processing quality directly affects the stability of signal transmission, so the processing process must strictly control the precision and process details.

[0003] To address the aforementioned issues, existing patents offer solutions. However, existing tension adaptive adjustment mechanisms in coaxial cable processing typically employ spring-driven tension compensation structures. These mechanisms buffer tension within a fixed range through spring elastic deformation, making it difficult to adapt in real-time to the dynamic tension fluctuations caused by changes in the wire feeding speed during coaxial cable processing. This affects the transmission stability of the coaxial cable during processing. Furthermore, during the wire feeding process, when the coaxial cable shifts laterally due to factors such as reduced wire feed wheel diameter or installation eccentricity, it is difficult to adjust the limiting range in real-time to match the offset trajectory of the coaxial cable. This results in the coaxial cable easily rubbing against the fixed limiting components during transport, affecting the accuracy of subsequent tension adjustment.

[0004] To address this, a tension adaptive adjustment mechanism for coaxial machining is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a tension adaptive adjustment mechanism for coaxial cable machining. This mechanism addresses the problem that existing tension adaptive adjustment mechanisms for coaxial cable machining typically employ spring-driven tension compensation structures. These mechanisms use spring elastic deformation to buffer tension within a fixed range, which is not conducive to real-time adaptation to the dynamic tension fluctuations caused by changes in the wire feeding speed during coaxial cable machining. This affects the transmission stability of the coaxial cable during machining. Furthermore, during the wire feeding process, when the coaxial cable shifts laterally due to factors such as reduced wire feeding wheel diameter or installation eccentricity, it is difficult to adjust the limiting range in real time to match the offset trajectory of the coaxial cable. This leads to the coaxial cable easily rubbing against the fixed limiting components during transport, affecting the accuracy of subsequent tension adjustment.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 The present invention provides the following technical solution: A tension adaptive adjustment mechanism for coaxial machining includes a frame 1. A tension adjustment component 4 is provided on the left side of the frame 1, and a conveying limiting component 5 is provided on the right side of the frame 1. The tension adjustment component 4 includes a support frame 401 fixedly connected to the inner side of the frame 1. A lifting cylinder 402 is fixedly connected to the top of the support frame 401. A transmission seat 403 is fixedly connected to the telescopic end of the lifting cylinder 402. A linkage seat 404 is hinged to the bottom of the transmission seat 403. A limiting groove 405 is provided on the front side of the support frame 401. An adjusting support 406 is slidably connected to the inner side of the limiting groove 405. The side of the adjusting support 406 away from the support frame 401 is fixedly connected to the linkage seat 404. A tension adjustment roller group 407 is rotatably connected to the outer side of the adjusting support 406.

[0019] In this embodiment: when it is necessary to adjust the tension of the coaxial cable, the lifting cylinder 402 at the top of the support frame 401 extends and retracts according to the command of the control main board 11. Its extension end drives the transmission seat 403 to move up and down. The bottom of the transmission seat 403 is hinged to the linkage seat 404. The movement of the transmission seat 403 will cause the linkage seat 404 to change angle, thereby pushing the adjusting support 406, which is fixedly connected to the linkage seat 404, to slide along the limiting slide groove 405 on the front side of the support frame 401. The tension adjusting roller group 407, which is rotatably connected to the outside of the adjusting support 406, moves synchronously with the adjusting support 406. Since the tension adjusting roller group 407 consists of three rollers, its position change will change the contact angle and tension between the coaxial cable and the three rollers, thereby realizing the adaptive adjustment of the coaxial cable tension. When the coaxial cable tension is too large, the position of the tension adjusting roller group 407 is adjusted to reduce the tension. When the tension is too small, the adjustment increases the tension, ultimately ensuring that the tension of the coaxial cable is stable during the processing.

[0020] Specifically, such as Figure 4 As shown, the conveying limiting component 5 includes a limiting bracket 501 fixedly connected to the outside of the frame 1. Both sides of the inside of the limiting bracket 501 are fixedly connected to a fixing seat 502, and a control motor 503 is fixedly connected to the outside of the limiting bracket 501.

[0021] Specifically, such as Figure 4 As shown, the output end of the control motor 503 is connected to the rotating shaft 504 via a transmission belt and a transmission wheel. The rotating shaft 504 is rotatably connected to the fixed base 502, and a rotating support 505 is fixedly connected to the outside of the rotating shaft 504.

[0022] Specifically, such as Figure 4 As shown, a rotating support 505 is fixedly connected to a rotating connecting rod 506 on the side away from the fixed base 502, and a limit roller 507 is fixedly connected to the inner side of the rotating connecting rod 506.

[0023] In this embodiment: when the coaxial cable is released from the pay-off reel 3, the control motor 503 on the outside of the limiting bracket 501 is started. Its output end drives the rotating shaft 504 to rotate on the fixed seat 502 through the transmission belt and transmission wheel. When the rotating shaft 504 rotates, the rotating support 505 on its outside moves synchronously. The rotating support 505 is connected to a rotating connecting rod 506 on the side away from the fixed seat 502. The rotating connecting rod 506 moves with the rotating support 505, thereby driving the inner limiting roller 507 to adjust its angle. The two limiting rollers 507 can adapt to the positional deviation of the coaxial cable caused by the reduction of the winding diameter or the installation eccentricity of the pay-off reel 3 through the angle change. They always fit against both sides of the coaxial cable to form a stable limiting space, avoiding lateral deviation or shaking of the coaxial cable during the conveying process, and ensuring that the coaxial cable enters the tension adjustment component 4 in a stable posture.

[0024] Specifically, such as Figure 1 , Figure 2 As shown, a rotary motor 2 is fixedly connected to the rear side of the frame 1, and a wire feeding wheel 3 is fixedly connected to the output end of the rotary motor 2.

[0025] Specifically, such as Figure 5 As shown, a drive motor 6 is fixedly connected to the rear side of the frame 1, and a conveyor roller group 7 is installed at the output end of the drive motor 6 through a transmission shaft and a synchronous belt.

[0026] In this embodiment: By setting a rotary motor 2 and a wire feeding wheel 3, when the rotary motor 2 is started, its output end directly drives the wire feeding wheel 3 to rotate. The coaxial cable is wound on the wire feeding wheel 3. As the wire feeding wheel 3 rotates, the coaxial cable is continuously released to provide raw materials for subsequent processing. By setting a drive motor 6 and a conveyor roller group 7, after the drive motor 6 is started, the power generated by its output end is transmitted to the synchronous belt through the transmission shaft. The synchronous belt then drives the conveyor roller group 7 to rotate. The conveyor roller group 7 is composed of two rollers. After the tension of the coaxial cable is adjusted by the tension adjustment component 4, it enters between the two rollers and is conveyed to the left under the action of the rotation of the conveyor roller group 7. The drive motor 6 can precisely control the speed of the conveyor roller group 7 through the transmission shaft and the synchronous belt, so that it matches the running speed of the wire feeding wheel 3 and the tension adjustment component 4, avoiding the accumulation or pulling of the coaxial cable during the conveying process, and ensuring that the coaxial cable moves continuously and stably to the subsequent process.

[0027] Specifically, such as Figure 1 , Figure 2 As shown, a support plate 8 is fixedly connected to the left side of the frame 1, and a guide roller 9 is provided on the left side of the support plate 8.

[0028] Specifically, such as Figure 1 , Figure 2 As shown, a support rod 10 is fixedly connected to the outer side of the frame 1, and a control main board 11 is fixedly connected to the front side of the support rod 10.

[0029] In this embodiment: By setting a support plate 8 and a guide roller 9, the coaxial cable is conveyed by the conveying roller group 7 and enters the guiding range of the guide roller 9. The guide roller 9, through its own rotation, adheres to the surface of the coaxial cable and guides it to the preset path. Through the guiding action of the guide roller 9, the slight deviation that may occur in the coaxial cable during the conveying process can be corrected, ensuring that the coaxial cable enters the next processing step with an accurate posture, avoiding the impact of path deviation on the subsequent processing accuracy. By setting a support rod 10 and a control main board 11, the control main board 11 coordinates the operation of various components such as the rotary motor 2, drive motor 6, control motor 503, and lifting cylinder 402 through preset programs and real-time detection signals. When the control main board 11 receives a tension change signal, it sends an adjustment command to the lifting cylinder 402. After receiving a coaxial cable position offset signal, it controls the control motor 503 to adjust the angle of the limit roller 507. Through the coordination of the control main board 11, the various components can cooperate in an orderly manner, ensuring that the tension adjustment, position limit, and conveying links are synchronized, realizing the automation and stability of the coaxial cable processing process.

[0030] Working principle: When processing the coaxial cable, the main control board 11 first controls the operation of each component. The rotary motor 2 is started, which drives the feed wheel 3 at the output end to rotate. The coaxial cable is released from the feed wheel 3 and enters the conveying limit assembly 5. The limit bracket 501 of the conveying limit assembly 5 is fixed to the outside of the frame 1. The fixed seats 502 on both sides inside the assembly provide rotational support for the rotating shaft 504. After the control motor 503 on the outside of the limit bracket 501 is started, the output end drives the rotating shaft 504 to rotate via the transmission belt and transmission wheel. When the rotating shaft 504 rotates, it drives the outer rotating support 5... 05 Synchronous movement: A rotating link 506 is connected to the side of the rotating support 505 away from the fixed base 502. The rotating link 506 moves with the rotating support 505, thereby driving the inner limiting roller 507 to adjust its angle. Through the cooperation of the two limiting rollers 507, it can adapt to the change in the position of the coaxial line during the wire feeding process of the wire feeding wheel 3, ensuring that the coaxial line enters the subsequent stage with a stable posture. After passing through the conveying limiting component 5, the coaxial line enters the tension adjusting component 4. The lifting cylinder 402 at the top of the support frame 401 extends and retracts according to the control command, and the transmission seat 403 at its extension end moves up and down accordingly. The linkage seat 404, hinged to the bottom of the transmission seat 403, changes angle due to its movement, which in turn pushes the adjusting support 406, which is fixedly connected to the linkage seat 404, to slide within the limiting groove 405 on the front side of the support frame 401. The tension adjusting roller group 407, rotatably connected to the outside of the adjusting support 406, changes position as the adjusting support 406 slides. Since the tension adjusting roller group 407 consists of three rollers, its position adjustment allows for different tension levels on the coaxial cable through the three rollers, thereby achieving adaptive adjustment of the coaxial cable tension and ensuring stable tension during processing. After force adjustment, the coaxial cable enters the conveyor roller group 7. The drive motor 6 on the rear side of the frame 1 starts, and its output end drives the conveyor roller group 7 to rotate through the transmission shaft and synchronous belt. The conveyor roller group 7 consists of two rollers. Through the cooperation of the two, the coaxial cable is conveyed to the left. Then, the coaxial cable passes through the guide roller 9 on the left support plate 8 of the frame 1. The guide roller 9 guides the coaxial cable to ensure that it enters the next processing step along the preset path. Throughout the process, the components cooperate in an orderly manner under the coordinated control of the control main board 11 to achieve the coordinated operation of stable position and adaptive tension adjustment during the processing of the coaxial cable.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
