Description

Technical Field

[0001] This utility model relates to the field of cable testing technology, and more specifically to a device for detecting surface defects in cables after insulation extrusion. Background Technology

[0002] During the cable production process, many factors, such as an uneven die surface, a die hole that is too small, a die hole that becomes larger after wear, or insulation extrusion, can easily lead to appearance defects in cables.

[0003] Existing cable surface defect detection devices use laser scanning for detection. However, it is difficult to rotate and adjust the cable in the current technology. Since the cable surface has a ring structure, it is difficult to detect the cable from all angles during laser scanning. Manual adjustment of the cable is required, which reduces the working efficiency of the detection device. Utility Model Content

[0004] The purpose of this invention is to provide a device for detecting surface defects in cables after insulation extrusion, in order to solve the problem mentioned in the background art that it is difficult to rotate and adjust the cable. Because the cable surface has a ring structure, it is difficult to fully detect the cable during laser scanning, and manual adjustment of the cable is required, which reduces the working efficiency of the detection device.

[0005] To achieve the above objectives, this utility model provides a device for detecting surface defects in cables after insulation extrusion, comprising a workbench, with rectangular frames fixedly installed on both sides of the top of the workbench, and clamping components for fixing cables installed within each of the two rectangular frames. A rectangular groove is formed on the surface of the workbench, and a lead screw is rotatably installed within the rectangular groove. A driving component connected to the lead screw is installed at the bottom of the workbench, and a screw block is threaded onto the lead screw. A fixing ring is fixedly installed on the top of the screw block, and a support ring is rotatably installed inside the fixing ring. Fixing rings extend from both ends of the support ring and are fixedly installed with mounting rings. Two fixing plates are fixedly installed on the side of the mounting ring, and laser emitters are installed on both fixing plates. An adjustment component for driving the support ring to rotate is installed at the top of the fixing ring.

[0006] By adopting the above solution, the support ring is rotated by adjusting the components, which in turn causes the mounting ring to rotate the two fixed plates and the two laser emitters. By adjusting the angle and position of the two laser emitters, defects on the cable surface can be detected from all angles, thus improving the efficiency of cable inspection.

[0007] As a further improvement to this technical solution, the clamping assembly includes a lower clamping block and an upper clamping block. The lower clamping block is fixed to the bottom of the inner side of the rectangular frame. A screw is threadedly connected to the top of the rectangular frame. The bottom end of the screw is rotatably connected to the top of the upper clamping block. A knob is provided at the top end of the screw.

[0008] By adopting the above scheme, rotating the two knobs drives the two screws to rotate, which in turn drives the two upper clamping blocks to move downward, so that the two upper clamping blocks clamp the upper end of the cable, thereby clamping and fixing the cable.

[0009] As a further improvement to this technical solution, limit blocks are fixedly provided on both sides of the top of the upper clamping block, and a limit groove adapted to the two limit blocks is opened on the inner side wall of the rectangular frame.

[0010] By adopting the above scheme, the movement of the upper clamping block is limited by two limiting blocks and limiting grooves.

[0011] As a further improvement to this technical solution, the drive assembly includes a first motor, which is fixedly mounted on the bottom of the workbench. A drive wheel is fixedly mounted on the output end of the first motor. One end of the lead screw passes through the workbench and is fixedly mounted on a driven wheel. A belt is provided between the drive wheel and the driven wheel.

[0012] By adopting the above scheme, the first motor drives the driving wheel, which in turn drives the driven wheel to rotate via a belt. The driven wheel then drives the lead screw to rotate, providing power for the movement of the fixed ring.

[0013] As a further improvement to this technical solution, the adjustment component includes a second motor, which is fixedly mounted on the top of the fixing ring. A gear is fixedly mounted on the output end of the second motor, and a gear ring is fixedly mounted on the outer circumference of the mounting ring. The gear and the gear ring are meshed and connected.

[0014] By adopting the above scheme, the second motor drives the gear to rotate, the gear drives the gear ring to rotate, and the gear ring drives the mounting ring to rotate, providing power for the rotation of the support ring.

[0015] As a further improvement to this technical solution, a bottom block is fixedly provided at the bottom of the screw block, and a groove is opened at the bottom of the rectangular groove to slide and adapt to the bottom block.

[0016] By adopting the above scheme, the movement of the screw block is limited by the bottom block and the slot.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting up an installation ring, a second motor drives a gear to rotate, which in turn drives a gear ring to rotate, which in turn drives the installation ring to rotate. This causes the installation ring to rotate two fixed plates and two laser emitters. By adjusting the angle and position of the two laser emitters, defects on the cable surface can be detected from all angles, thus improving the efficiency of cable inspection.

[0018] 2. By setting a support ring, the first motor drives the drive wheel, which in turn drives the driven wheel to rotate via a belt. The driven wheel then drives the lead screw to rotate, which in turn drives the screw block to move horizontally. The screw block then drives the fixed ring and the support ring to move horizontally, which in turn drives the two fixed plates and the two laser emitters to move horizontally. This allows for comprehensive inspection of defects on the cable surface, further improving the efficiency of cable inspection. Attached Figure Description

[0023] Please see Figures 1-5 As shown, this utility model provides a device for detecting surface defects in cables after insulation extrusion. It includes a workbench 1, with rectangular frames 2 fixedly mounted on both sides of the top of the workbench 1. Each rectangular frame 2 contains a clamping assembly for fixing the cable. The clamping assembly includes a lower clamping block 11 and an upper clamping block 12. The lower clamping block 11 is fixed to the bottom inner side of the rectangular frame 2. A screw 13 is threadedly connected to the top of the rectangular frame 2. The bottom end of the screw 13 is rotatably connected to the top of the upper clamping block 12. A knob 14 is located at the top of the screw 13 to guide the cable through. The cable is placed on the lower clamping blocks 11 inside the two rectangular frames 2. The two knobs 14 are rotated to drive the two screws 13 to rotate, which in turn drives the two upper clamping blocks 12 to move downward, so that the two upper clamping blocks 12 clamp the upper end of the cable, thereby clamping and fixing the cable. Limiting blocks 15 are fixedly installed on both sides of the top of the upper clamping blocks 12. The inner side wall of the rectangular frame 2 is provided with limiting grooves that are adapted to the two limiting blocks 15. The movement of the upper clamping blocks 12 is limited by the two limiting blocks 15.

[0024] A rectangular groove 3 is formed on the surface of the workbench 1. A lead screw 4 is rotatably mounted in the rectangular groove 3. A drive assembly connected to the lead screw 4 is located at the bottom of the workbench 1. The drive assembly includes a first motor 16, which is fixedly mounted at the bottom of the workbench 1. A drive wheel 17 is fixedly mounted at the output end of the first motor 16. One end of the lead screw 4 passes through the workbench 1 and is fixedly mounted on a driven wheel 18. A belt 19 is provided between the drive wheel 17 and the driven wheel 18. The first motor 16 drives the drive wheel 17, which in turn drives the driven wheel 18 to rotate via the belt 19. The driven wheel 18 drives the lead screw 4 to rotate. A screw block 5 is threaded onto the lead screw 4. A retaining ring 6 is fixedly mounted on the top of the screw block 5. A support ring 7 is rotatably mounted inside the retaining ring 6. The rotation of the lead screw 4 causes the screw block 5 to move horizontally. The screw block 5 drives the fixed ring 6 and the support ring 7 to move horizontally. The fixed ring 6 extends from both ends of the support ring 7 and is fixedly mounted with mounting rings 8. The outer surface of the support ring 7 slides against the inner surface of the fixed ring 6. The two mounting rings 8 contact the two ends of the fixed ring 6 respectively, and restrict the support ring 7 so that the support ring 7 will not deviate during rotation. Two fixing plates 9 are fixedly mounted on the side of the mounting ring 8. Laser emitters 10 are mounted on both fixing plates 9. Laser reflection is used to analyze cable surface defects. By setting two laser emitters 10 for operation, the detection efficiency is improved. A bottom block 23 is fixedly mounted at the bottom of the screw block 5. The bottom of the rectangular groove 3 has a slot that slides and adapts to the bottom block 23. The bottom block 23 limits the movement of the screw block 5.

[0025] The top of the fixed ring 6 is equipped with an adjustment component that drives the support ring 7 to rotate. The adjustment component includes a second motor 20, which is fixedly mounted on the top of the fixed ring 6. A gear 21 is fixedly mounted on the output end of the second motor 20. A gear ring 22 is fixedly mounted on the outer periphery of the mounting ring 8. The gear 21 and the gear ring 22 are meshed and connected. The second motor 20 drives the gear 21 to rotate, which in turn drives the gear ring 22 to rotate. The gear ring 22 drives the mounting ring 8 to rotate, which in turn drives the support ring 7 to rotate. At the same time, the mounting ring 8 drives the two fixed plates 9 and the two laser emitters 10 to rotate. By adjusting the angle position of the two laser emitters 10, defects on the surface of the cable can be detected from all angles.

[0026] The specific working principle of this utility model is as follows: The cable is passed through two rectangular frames 2, with both ends of the cable placed on the lower clamping blocks 11 within the two rectangular frames 2. Rotating the two knobs 14 drives the two screws 13 to rotate, which in turn moves the two upper clamping blocks 12 downwards, clamping the upper ends of the cable and thus securing it. The second motor 20 drives the gear 21 to rotate, which in turn drives the gear ring 22 to rotate. The gear ring 22 then drives the mounting ring 8 to rotate, which in turn drives the support ring 7 to rotate. Simultaneously, the mounting ring 8 drives the two fixing plates 9 and... Two laser emitters 10 rotate, and by adjusting the angle of the two laser emitters 10, defects on the cable surface can be detected from all angles. The first motor 16 drives the drive wheel 17, which drives the driven wheel 18 to rotate via the belt 19. The driven wheel 18 drives the lead screw 4 to rotate, which in turn drives the screw block 5 to move horizontally. The screw block 5 drives the fixing ring 6 and the support ring 7 to move horizontally, which in turn drives the two fixing plates 9 and the two laser emitters 10 to move horizontally, thereby conducting a comprehensive inspection of defects on the cable surface and improving the efficiency of cable inspection.
