Description

Technical Field

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

[0002] During the cable processing, the reasons for deformation are relatively complex. Improper control of the composition ratio or uneven mixing of the conductor materials used in cable manufacturing will result in differences in the properties of various parts of the materials. For example, the density of some regions in the insulating material is relatively large, while that of other regions is small. During subsequent processing or use, the expansion and contraction characteristics of different density regions are inconsistent, thus causing cable deformation. Moreover, different materials have different coefficients of thermal expansion. The difference in the coefficients of thermal expansion between the conductor and the insulating layer of the cable is relatively large. When the temperature changes during the processing, the expansion or contraction degrees of the conductor and the insulating layer are different, generating stress between them, and further causing the cable to deform. During the 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 prior art, a contact probe is often used to detect the deformation of the cable. However, during the transmission and movement of the cable, vibrations and jitters will occur, which will affect the deformation detection result and thus cause limitations.

[0003] Therefore, we propose a deformation detection device for cable processing. Summary of the Invention

[0004] Aiming at 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 art.

[0005] To achieve the above object, the present invention provides the following technical solution: A deformation detection device for cable processing, comprising: A base, a bracket, a transmission wheel, a limiting ring and a mounting frame; the bracket and the transmission wheel are installed on the base; two of the limiting rings are installed on the bracket; spring telescopic rods are evenly installed in the limiting ring; a clamping block is fixedly connected to the end of the spring telescopic rod; a ball is installed on the clamping block. Two of the mounting frames are located between the two limiting rings, and a detection component is arranged in the mounting frame; the detection component includes a detection needle, a detection spring and a detection sensor; the detection sensor is installed on the mounting frame; the detection spring is installed on the detection sensor; the detection needle is fixedly connected to the detection spring. An installation ring is fixedly connected to the bracket; a connection ring is connected to the installation ring; the two installation frames are rotatably connected and fixed by bolts; contact blocks are slidably connected to both sides of the installation frame; the contact blocks are fixed by bolts; the installation frame and the connection ring are movably connected, enabling the installation frame to shake.

[0006] Preferably, a connection spring is fixedly connected between the installation frame and the connection ring.

[0007] By arranging limiting rings and clamping blocks on both sides of the installation frame to reduce the jitter and vibration of the cable, then clamping the installation frame on the outer surface of the cable, and allowing the installation frame to shake together with the cable, the influence of cable jitter on the detection result is reduced, making the detection result of cable deformation more accurate.

[0008] Preferably, comparison grooves are provided on both sides of the installation frame; detection needles, detection springs, and detection sensors are also arranged in the comparison grooves; the comparison grooves are annularly distributed on the installation frame.

[0009] By arranging comparison grooves in the installation frame, the detection needles and detection springs in the comparison grooves are not restricted and can move under the action of their own inertia. After the detection sensors in the comparison grooves detect the magnitude of the inertial force, the magnitude of the inertial force of the detection needles and detection springs is subtracted from the detection sensors for detecting cable deformation, thereby reducing the change in the force transmitted to the detection sensors due to the influence of their own inertia when the detection needles and detection springs swing with the cable, and further making the detection result of the present invention more accurate.

[0010] Preferably, a synchronous gear is rotatably connected to the installation frame; the two synchronous gears on the two installation frames 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; the synchronous rod and the sliding block are slidably matched.

[0011] Preferably, the connection ring is rotatably connected to the installation ring; a toothed ring is fixedly connected to the connection ring; a deflection motor is fixedly connected to the installation ring; a gear is fixedly connected to the output end of the deflection motor, and the gear meshes with the toothed ring.

[0012] Preferably, adjustment grooves are uniformly axially arranged in the installation frame; the shape of the adjustment grooves is arc-shaped, and adjustment blocks are slidably connected in the adjustment grooves along the arc direction; the adjustment blocks are fixed by bolts on the installation frame.

[0013] Preferably, telescopic grooves are uniformly spaced on the adjustment blocks; telescopic blocks are slidably connected in the telescopic grooves; adjustment screws are threadedly connected to the telescopic blocks; the adjustment screws are rotatably connected to the adjustment blocks.

[0014] By setting synchronous gears and synchronous rods on the mounting brackets, the contact blocks on the two mounting brackets move synchronously, so that the sliding distances of the contact blocks on the two mounting brackets are the same, thereby ensuring that the cable is always in the middle position of the mounting bracket.

[0015] Advantages of the present invention: 1. By setting limiting rings and clamping blocks on both sides of the mounting bracket, the jitter and vibration of the cable are reduced. Then, the mounting bracket is clamped on the outer surface of the cable, and the mounting bracket shakes together with the cable, thereby reducing the influence of the cable jitter on the detection result and making the detection result of the cable deformation more accurate.

[0016] 2. By setting a comparison groove in the mounting bracket, the detection needle and the detection spring in the comparison groove are not restricted and can move under the action of their own inertia. After the detection sensor in the comparison groove detects the magnitude of the inertia force, the magnitude of the inertia force of the detection needle and the detection spring is subtracted from the detection sensor for detecting the cable deformation, thereby reducing the change in the force transmitted to the detection sensor due to the influence of its own inertia when the detection needle and the detection spring swing with the cable, and further making the detection result of the present invention more accurate.

[0017] 3. By setting synchronous gears and synchronous rods on the mounting brackets, the contact blocks on the two mounting brackets move synchronously, so that the sliding distances of the contact blocks on the two mounting brackets are the same, thereby ensuring that the cable is always in the middle position of the mounting bracket.

Detailed implementation mode

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1: Refer to the attached drawings of the specification Figures 1 to 5 , a deformation detection device for cable processing, comprising: A base 1, a bracket 11, a transmission wheel 12, a limiting ring 13 and a mounting bracket 14; the bracket 11 and the transmission wheel 12 are mounted on the base 1; two limiting rings 13 are mounted on the bracket 11; spring telescopic rods 15 are evenly mounted inside the limiting rings 13; the ends of the spring telescopic rods 15 are fixedly connected with clamping blocks 16; balls are mounted on the clamping blocks 16; Two mounting brackets 14 are located between the two limiting rings 13, and a detection component is arranged inside the mounting bracket 14; the detection component includes a detection needle 21, a detection spring 22 and a detection sensor 23; the detection sensor 23 is mounted on the mounting bracket 14; the detection spring 22 is mounted on the detection sensor 23; the detection needle 21 is fixedly connected with the detection spring 22; A mounting ring 3 is fixedly connected to the bracket 11; a connecting ring 31 is connected to the mounting ring 3; the two mounting brackets 14 are rotatably connected and fixed by bolts; contact blocks 32 are slidably connected to both sides of the mounting bracket 14; the contact blocks 32 are fixed by bolts; the mounting bracket 14 and the connecting ring 31 are movably connected, so that the mounting bracket 14 can shake.

[0022] In the present invention, a connecting spring 33 is fixedly connected between the mounting bracket 14 and the connecting ring 31.

[0023] 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 epidermis to reduce friction; a ball is arranged at the top of the detection needle 21 on the mounting bracket 14, and the ball at the top of the detection needle 21 is in contact with the cable epidermis. When the insulating layer of the cable epidermis deforms, the detection needle 21 fits the cable epidermis, so that the pressure transmitted to the detection sensor 23 through the detection spring 22 changes, and then it is detected that the insulating layer of the cable epidermis deforms. According to the magnitude of the pressure change received by the detection sensor 23, the magnitude of the deformation of the insulating layer of the cable epidermis is detected; During the transmission of the cable, vibration and jitter will occur. 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 jitter of the cable. At the same time, the two mounting brackets 14 are clamped on the outside of the cable and move with the jitter of the cable, so that the cable, the mounting bracket 14, the detection needle 21 and the detection spring 22 inside 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, so that the influence of cable vibration or jitter on the detection result is reduced; In the present invention, by arranging the limiting rings 13 and the clamping blocks 16 on both sides of the mounting bracket 14, the jitter and vibration of the cable are reduced. Then the mounting bracket 14 is clamped on the outer surface of the cable, and the mounting bracket 14 jitters together with the cable, thereby reducing the influence of cable jitter on the detection result and making the detection result of cable deformation more accurate.

[0024] In the present invention, comparison grooves 4 are provided on both sides of the mounting bracket 14; detection needles 21, detection springs 22 and detection sensors 23 are also arranged in the comparison grooves 4; the comparison grooves 4 are annularly distributed on the mounting bracket 14.

[0025] In the present invention, comparison grooves 4 are arranged on the mounting bracket 14. The detection needles 21 in the comparison grooves 4 do not contact the cable. When the mounting bracket 14 jitters with the cable, the detection needles 21 and the detection springs 22 in the comparison grooves 4 also jitter with the cable. When the detection needles 21 and the detection springs 22 in the mounting bracket 14 move, due to their own inertia factors, the value transmitted to the detection sensor 23 will deviate. When the detection needles 21 and the detection springs 22 in the comparison grooves 4 swing with the cable, the force will be transmitted to the detection sensor 23 in the comparison grooves 4 due to inertia. Therefore, the detection sensor 23 in the comparison grooves 4 detects the force received by the detection needles 21 and the detection springs 22 due to inertia. Therefore, the detection sensor 23 corresponding to the detection needle 21 in contact with the cable cancels the force received by the detection sensor 23 in the comparison grooves 4, so that the influence of the inertia of the detection needles 21 and the detection springs 22 can be eliminated, and further the detection results of the detection needles 21, the detection springs 22 and the detection sensors 23 are more accurate; In the present invention, by arranging comparison grooves 4 in the mounting bracket 14, the detection needles 21 and the detection springs 22 in the comparison grooves 4 are not restricted and can move under the action of their own inertia. Therefore, after the detection sensor 23 in the comparison grooves 4 detects the magnitude of the inertial force, the detection sensor 23 for detecting cable deformation subtracts the magnitude of the inertial force of the detection needles 21 and the detection springs 22, so as to reduce the change in the force transmitted to the detection sensor 23 due to the influence of the inertia of the detection needles 21 and the detection springs 22 when they swing with the cable, and further make the detection result of the present invention more accurate.

[0026] Embodiment 2: On the basis of Embodiment 1, referring to the appended drawings of the specification Figures 1 to 5, in the present invention, a synchronous gear 5 is rotatably connected to the mounting bracket 14; the two synchronous gears 5 on the two mounting brackets 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; the synchronous rod 52 is slidably mated with the sliding block 51 on the contact block 32.

[0027] , in the present invention, the connecting ring 31 is rotatably connected to the mounting ring 3; a toothed 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 meshes with the toothed ring.

[0028] , in the present invention, adjusting grooves 6 are uniformly axially formed in the mounting bracket 14; the adjusting grooves 6 are arc-shaped, and adjusting blocks 61 are slidably connected in the adjusting grooves 6 along the arc direction; the adjusting blocks 61 are fixed by bolts on the mounting bracket 14.

[0029] , in the present invention, telescopic grooves 62 are uniformly formed at intervals on the adjusting blocks 61; telescopic blocks 63 are slidably connected in the telescopic grooves 62; adjusting screws 64 are threadedly connected to the telescopic blocks 63; the adjusting screws 64 are rotatably connected to the adjusting blocks 61.

[0030] , in the present invention, the synchronous gear 5 and the synchronous rod 52 are provided on the mounting bracket 14. During the rotation of the two mounting brackets 14, the synchronous gear 5 is driven to rotate, so that the two synchronous gears 5 and the synchronous rod 52 rotate to the same degree. Moreover, the synchronous rod 52 is slidably mated with the sliding block 51 on the contact block 32. Therefore, when the synchronous rod 52 rotates, the contact block 32 is driven to move, so that the sliding distances of the contact blocks 32 on the two mounting brackets 14 are the same. Therefore, when the contact blocks 32 clamp the cable, the two contact blocks 32 will not be asymmetric in position, and after clamping the cable, the cable will not shift to one side in the mounting bracket 14, ensuring that the cable is always in the middle position of the mounting bracket 14; , 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. Therefore, during the deformation detection of the cable by the detection needle 21 on the mounting bracket 14, it can rotate back and forth periodically. 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 surface of the cable can be detected; By loosening the bolts on the mounting bracket 14, the adjusting block 61 can slide in the adjusting groove 6, so that the detection distance of the detection needle 21 on the same mounting bracket 14 in the circumferential direction of the cable can be adjusted. Then, by turning the adjusting screw 64, the telescopic block 63 drives the detection needle 21 to move, and the position of the top of the detection needle 21 can be adjusted, so that the detection needle 21 can adapt to cables of different thicknesses; In the present invention, by providing a synchronous gear 5 and a synchronous rod 52 on the mounting bracket 14, the contact blocks 32 on the two mounting brackets 14 are synchronously moved, so that the sliding distances of the contact blocks 32 on the two mounting brackets 14 are the same, thereby ensuring that the cable is always in the middle position of the mounting bracket 14.
