Description

Technical Field

[0001] The present invention relates to the technical field of deformation detection devices, and in particular to a deformation detection device used for cable processing. Background Art

[0002] The causes of cable deformation during processing are complex. Improper control of the proportions of conductor materials used in cable manufacturing or uneven mixing can lead to differences in the performance of various parts of the material. For example, the density of some areas of the insulation material is higher, while that of other areas is lower. During subsequent processing or use, the expansion and contraction characteristics of different density areas are inconsistent, causing cable deformation. In addition, different materials have different thermal expansion coefficients. The thermal expansion coefficients of the conductor and insulation layer of the cable differ greatly. When encountering temperature changes during processing, the conductor and insulation layer expand or contract to different degrees, generating stress between them, which in turn causes cable deformation.

[0003] During cable processing, a deformation detection device is needed to detect the degree of cable deformation to ensure that the cable meets the requirements. In the existing technology, contact probes are often used to detect cable deformation. However, during the transmission and movement of the cable, vibration and jitter will occur, which will affect the deformation detection results and cause limitations.

[0004] To this end, we propose a deformation detection device for cable processing. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a deformation detection device for cable processing, which overcomes the deficiencies of the prior art and aims to solve the problems in the background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a deformation detection device for cable processing, comprising:

[0007] A base, a bracket, a transmission wheel, a limiting ring, and a mounting frame; the bracket and the transmission wheel are mounted on the base; two limiting rings are mounted on the bracket; spring telescopic rods are evenly mounted in the limiting rings; the ends of the spring telescopic rods are fixedly connected to clamping blocks; and balls are mounted on the clamping blocks.

[0008] The two mounting brackets are located between the two limiting rings, and a detection assembly is provided in the mounting brackets; the detection assembly includes a detection needle, a detection spring, and a detection sensor; the detection sensor is mounted on the mounting brackets; the detection spring is mounted on the detection sensor; the detection needle is fixedly connected to the detection spring;

[0009] The bracket is fixed with a mounting ring; the mounting ring is connected to a connecting ring; the two mounting brackets are rotatably connected and fixed by bolts; contact blocks are slidably connected to both sides of the mounting bracket; the contact blocks are fixed by bolts; the mounting bracket and the connecting ring are movably connected so that the mounting bracket can shake.

[0010] Preferably, a connecting spring is fixedly connected between the mounting bracket and the connecting ring.

[0011] By setting limiting rings and clamping blocks on both sides of the mounting frame, the jitter and vibration of the cable are reduced. The mounting frame is then clamped on the outer surface of the cable and allowed to vibrate along with the cable, thereby reducing the impact of cable jitter on the test results and making the detection results of cable deformation more accurate.

[0012] Preferably, control grooves are provided on both sides of the mounting frame; detection needles, detection springs and detection sensors are also provided in the control grooves; and the control grooves are distributed in a ring shape on the mounting frame.

[0013] By arranging a control groove in the mounting frame, the detection needle and detection spring in the control groove are not constrained and can move under the action of their own inertia. Therefore, after the detection sensor in the control groove detects the magnitude of the inertial force, the detection sensor that detects the cable deformation subtracts the magnitude of the inertial force of the detection needle and detection spring, thereby reducing the influence of the detection needle and detection spring's own inertia when the cable swings, and reducing the change in the force transmitted to the detection sensor, thereby making the detection result of the present invention more accurate.

[0014] Preferably, a synchronous gear is rotatably connected to the mounting bracket; the two synchronous gears on the two mounting brackets can mesh with each other; a sliding block is fixedly connected to the contact block; a synchronous rod is fixedly connected to the synchronous gear; and the synchronous rod and the sliding block are slidably engaged with each other.

[0015] Preferably, the connecting ring is rotatably connected to the mounting ring; a gear ring is fixedly connected to the connecting ring; a deflection motor is fixedly connected to the mounting ring; a gear is fixedly connected to the output end of the deflection motor, and the gear is meshed with the gear ring.

[0016] Preferably, adjustment grooves are evenly opened in the axial direction of the mounting frame; the adjustment grooves are arc-shaped, and an adjustment block is slidably connected in the adjustment groove along the direction of the arc; the adjustment block is fixed by bolts on the mounting frame.

[0017] Preferably, the adjusting block is provided with telescopic slots at even intervals; the telescopic block is slidably connected in the telescopic slot; the telescopic block is threadedly connected with an adjusting screw; and the adjusting screw is rotatably connected to the adjusting block.

[0018] By arranging a synchronization gear and a synchronization rod on the mounting frame, the contact blocks on the two mounting frames move synchronously, so that the sliding distance of the contact blocks on the two mounting frames is the same, thereby ensuring that the cable is always in the middle position of the mounting frame.

[0019] Beneficial effects of the present invention:

[0020] 1. The present invention reduces the jitter and vibration of the cable by arranging limiting rings and clamping blocks on both sides of the mounting frame, and then clamps the mounting frame on the outer surface of the cable, allowing the mounting frame to vibrate along with the cable, thereby reducing the impact of cable jitter on the test results, making the detection results of cable deformation more accurate.

[0021] 2. The present invention sets a control groove in the mounting frame, and the detection needle and detection spring in the control groove are not constrained and can move under the action of their own inertia. Therefore, after the detection sensor in the control groove detects the magnitude of the inertial force, the detection sensor that detects the cable deformation subtracts the magnitude of the inertial force of the detection needle and detection spring, thereby reducing the influence of the detection needle and detection spring's own inertia when the cable swings, and reducing the change in the force transmitted to the detection sensor, thereby making the detection result of the present invention more accurate.

[0022] 3. The present invention provides a synchronization gear and a synchronization rod on the mounting frame, so that the contact blocks on the two mounting frames move synchronously, so that the sliding distance of the contact blocks on the two mounting frames is the same, thereby ensuring that the cable is always in the middle position of the mounting frame.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1: Refer to the attached Figures 1 to 5 , a deformation detection device for cable processing, comprising:

[0031] Base 1, bracket 11, transmission wheel 12, restriction ring 13 and mounting bracket 14; bracket 11 and transmission wheel 12 are mounted on base 1; two restriction rings 13 are mounted on bracket 11; spring telescopic rods 15 are evenly mounted inside restriction rings 13; the ends of spring telescopic rods 15 are fixedly connected to clamping blocks 16; and ball bearings are mounted on clamping blocks 16.

[0032] The two mounting brackets 14 are located between the two limiting rings 13. A detection assembly is disposed within the mounting brackets 14. The detection assembly includes a detection needle 21, a detection spring 22, and a detection sensor 23. The detection sensor 23 is mounted on the mounting brackets 14. The detection spring 22 is mounted on the detection sensor 23. The detection needle 21 is fixedly connected to the detection spring 22.

[0033] A mounting ring 3 is fixed to the bracket 11; a connecting ring 31 is connected to the mounting ring 3; the two mounting frames 14 are rotatably connected and fixed by bolts; contact blocks 32 are slidably connected to both sides of the mounting frame 14; the contact blocks 32 are fixed by bolts; the mounting frame 14 and the connecting ring 31 are movably connected, so that the mounting frame 14 can shake.

[0034] In the present invention, a connecting spring 33 is fixedly connected between the mounting bracket 14 and the connecting ring 31 .

[0035] In the present invention, the cable is transmitted through the transmission wheel 12, and the cable passes through the limiting ring 13. The contact blocks 32 on the two mounting brackets 14 are clamped on the surface of the cable, and the balls on the clamping blocks 16 are in contact with the cable skin to reduce friction. The top of the detection needle 21 on the mounting bracket 14 is provided with a round ball, and the round ball at the top of the detection needle 21 contacts the cable skin. When the insulation layer of the cable skin is deformed, the detection needle 21 is attached to the cable skin, so that the pressure transmitted to the detection sensor 23 by the detection spring 22 changes, and the deformation of the cable skin insulation layer is detected. The deformation of the cable skin insulation layer is detected according to the magnitude of the pressure change on the detection sensor 23.

[0036] During the transmission process, the cable will vibrate and shake. The clamping blocks 16 on the limiting rings 13 on both sides of the mounting bracket 14 clamp the cable, thereby reducing the vibration and shaking of the cable. At the same time, the two mounting brackets 14 clamp the outside of the cable and move with the shaking of the cable, so that the cable and the mounting bracket 14, as well as the detection needle 21 and the detection spring 22 in the mounting bracket 14, move synchronously. Therefore, except for the forward movement of the cable, the cable and the detection needle 21 are relatively stationary, thereby reducing the influence of cable vibration or shaking on the detection result.

[0037] The present invention reduces the jitter and vibration of the cable by arranging a limiting ring 13 and a clamping block 16 on both sides of the mounting frame 14, and then clamps the mounting frame 14 on the outer surface of the cable, and allows the mounting frame 14 to jitter along with the cable, thereby reducing the impact of the cable jitter on the detection result, making the detection result of the cable deformation more accurate.

[0038] In the present invention, control slots 4 are provided on both sides of the mounting frame 14 ; detection needles 21 , detection springs 22 and detection sensors 23 are also provided in the control slots 4 ; the control slots 4 are distributed in a ring shape on the mounting frame 14 .

[0039] In the present invention, a control slot 4 is provided on the mounting frame 14. The detection pin 21 in the control slot 4 does not contact the cable. When the mounting frame 14 vibrates with the cable, the detection pin 21 and the detection spring 22 in the control slot 4 also vibrate with the cable. When the detection pin 21 and the detection spring 22 in the mounting frame 14 move, the value transmitted to the detection sensor 23 will deviate due to their own inertia. When the detection pin 21 and the detection spring 22 in the control slot 4 swing with the cable, they will transmit force to the detection sensor 23 in the control slot 4 due to inertia. Therefore, the detection sensor 23 in the control slot 4 detects the force exerted on the detection pin 21 and the detection spring 22 by the inertia. Therefore, the detection sensor 23 corresponding to the detection pin 21 in contact with the cable eliminates the force exerted on the detection sensor 23 in the control slot 4, thereby eliminating the influence of the inertia of the detection pin 21 and the detection spring 22, thereby making the detection results of the detection pin 21, the detection spring 22 and the detection sensor 23 more accurate.

[0040] The present invention sets a control groove 4 in the mounting frame 14, and the detection needle 21 and the detection spring 22 in the control groove 4 are not constrained and can move under the action of their own inertia. Therefore, after the detection sensor 23 in the control groove 4 detects the magnitude of the inertial force, the detection sensor 23 that detects the cable deformation subtracts the magnitude of the inertial force of the detection needle 21 and the detection spring 22, thereby reducing the force transmitted to the detection sensor 23 due to the influence of the detection needle 21 and the detection spring 22 themselves when the cable swings, thereby making the detection result of the present invention more accurate.

[0041] Example 2: Based on Example 1, refer to the attached Figures 1 to 5 In the present invention, a synchronous gear 5 is rotatably connected to the mounting frame 14; the two synchronous gears 5 on the two mounting frames 14 can mesh with each other; a sliding block 51 is fixedly connected to the contact block 32; a synchronous rod 52 is fixedly connected to the synchronous gear 5; and the synchronous rod 52 and the sliding block 51 are slidably engaged with each other.

[0042] In the present invention, the connecting ring 31 is rotatably connected to the mounting ring 3; a gear ring is fixedly connected to the connecting ring 31; a deflection motor 53 is fixedly connected to the mounting ring 3; a gear is fixedly connected to the output end of the deflection motor 53, and the gear is meshed with the gear ring.

[0043] In the present invention, the mounting frame 14 is provided with adjustment slots 6 evenly arranged in the axial direction. The adjustment slots 6 are arc-shaped, and an adjustment block 61 is slidably connected in the adjustment slot 6 along the arc direction. The adjustment block 61 is fixed by bolts on the mounting frame 14 .

[0044] In the present invention, the adjusting block 61 is provided with evenly spaced expansion slots 62 ; the expansion slots 62 are slidably connected to the expansion block 63 ; the expansion block 63 is threadedly connected to the adjusting screw 64 ; the adjusting screw 64 is rotatably connected to the adjusting block 61 .

[0045] In the present invention, a synchronization gear 5 and a synchronization rod 52 are provided on the mounting frame 14. When the two mounting frames 14 rotate, the synchronization gear 5 is driven to rotate, so that the two synchronization gears 5 and the synchronization rod 52 rotate to the same extent. Moreover, the synchronization rod 52 is slidably matched with the sliding block 51 on the contact block 32. Therefore, when the synchronization rod 52 rotates, the contact block 32 is driven to move, so that the sliding distance of the contact blocks 32 on the two mounting frames 14 is the same. Therefore, when the contact blocks 32 clamp the cable, the positions of the two contact blocks 32 will not be asymmetrical. After clamping the cable, the cable will not be offset to one side in the mounting frame 14, ensuring that the cable is always in the middle position of the mounting frame 14.

[0046] In the present invention, the deflection motor 53 drives the corresponding gear to rotate, so that the connecting ring 31 drives the mounting bracket 14 to rotate through the connecting spring 33. As a result, the detection needle 21 on the mounting bracket 14 can periodically rotate back and forth during the deformation detection process of the cable. Therefore, the detection needle 21 can move circumferentially on the surface of the cable, thereby expanding the detection range and ensuring that all positions on the cable surface can be detected.

[0047] By loosening the bolts on the mounting bracket 14, the adjustment block 61 can slide in the adjustment slot 6, thereby adjusting the detection spacing of the detection needle 21 on the same mounting bracket 14 in the circumferential direction of the cable. Then, by turning the adjustment screw 64, the telescopic block 63 moves with the detection needle 21, and the position of the top end of the detection needle 21 can be adjusted, so that the detection needle 21 can adapt to cables of different thicknesses.

[0048] The present invention sets a synchronization gear 5 and a synchronization rod 52 on the mounting frame 14 so that the contact blocks 32 on the two mounting frames 14 move synchronously, so that the sliding distances of the contact blocks 32 on the two mounting frames 14 are the same, thereby ensuring that the cable is always in the middle position of the mounting frame 14.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
