Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable sheath thickness measurement, in particular to a kind of cable sheath thickness measuring device. BACKGROUND

[0002] Cable sheath thickness measurement is an important link to ensure cable quality and safe operation. Professional measuring tools such as micrometer, thickness gauge, etc. are usually used. Micrometer can directly contact the cable sheath for measurement, and the sheath thickness is accurately measured by rotating the screw rod. Thickness gauge uses ultrasonic wave, magnetic induction, etc. for non-contact measurement, which is suitable for occasions where direct contact is inconvenient. In cable sheath thickness measurement, projector measurement is a more accurate method. The projector projects the image of the cable sheath onto the screen, allowing the measurer to observe the details of the sheath more clearly. When measuring, place the cable on the projector's workbench, adjust the focus and light to make the sheath profile clear, then use the scale on the projector or measurement software to measure the thickness of the sheath. This method has the advantages of high measurement accuracy, accurate measurement of sheath thickness, and simultaneous observation of multiple parts of the sheath, improving measurement efficiency. In addition, projector measurement can record measurement results, facilitating subsequent data analysis and quality control. Accurate measurement of cable sheath thickness can ensure the insulation performance, mechanical strength and service life of the cable, prevent safety problems such as leakage and short circuit caused by thin sheath, and help effectively monitor cable quality during production and use.

[0003] For example, the patent with publication number CN119146866B discloses a kind of cable sheath's thickness measuring device, and the present application relates to the technical field of thickness measurement. The present application includes a camera, a camera is connected with a display screen, an observation assembly is fixedly connected to the top of the bottom plate, the camera is fixedly connected to the side close to the bottom plate and the observation assembly, the circular plate is made of acrylic material, the bottom of the projection assembly is slidably connected to the top of the bottom plate, the surface of the circular plate is fixedly connected to the inner side of the projection assembly, the driving assembly is limitingly and slidably connected to the side away from the bottom plate of the frame, the side away from the frame of the driving assembly is fixedly connected to the outer side of the projection assembly, the camera fixes the projection picture or changes with the movement of the driving assembly, the photo can form a contrast group, analyze the thickness relationship between different position slices on the same cable, and also can observe the thickness of different positions of the same slice in real time, the projection assembly provides light at the bottom of the slice, the contrast between the slice and the surrounding is larger, and the projection edge profile is clearer.

[0004] However, before measuring the thickness of the cable sheath, this thickness measuring device requires the cable sheath to be manually cut into multiple cable sheath slices. However, the manual cutting method will result in different heights of each cable sheath slice, which will cause errors between each control group when projected, thus reducing the accuracy of the cable sheath thickness measurement results. Summary of the Invention

[0005] To address the aforementioned problems in existing technologies, the technical problem this invention aims to solve is that existing thickness measuring devices require manual cutting of the cable sheath into multiple sheath slices before measuring its thickness.

[0028] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0029] See Figures 1-3 The present invention provides an embodiment of a cable sheath thickness measuring device, comprising: a light-transmitting plate 1, a slicing mechanism 2, a light source 3, and an observation and measurement mechanism 4; the slicing mechanism 2 sequentially cuts the cable sheath into multiple cable sheath slices of the same height and transports the cable sheath slices onto the light-transmitting plate 1; the light source 3 is positioned below the light-transmitting plate 1; the observation and measurement mechanism 4 is positioned above the light-transmitting plate 1 to observe and measure the projection of the cable sheath slices illuminated by the light source 3 on the light-transmitting plate 1; furthermore, the observation and measurement mechanism 4 can be a camera; the projection of the cable sheath slices is measured by a computer.

[0030] In practice, the slicing mechanism 2 is controlled to cut the cable sheath into multiple cable sheath slices of the same height, and then the cable sheath slices are transported to the light-transmitting plate 1. Then, the light source 3 is controlled to illuminate the cable sheath slices on the light-transmitting plate 1, so that the observation and measurement mechanism 4 can observe the projection of the cable sheath slices and measure the projection. In this way, the thickness of the cable sheath can be accurately measured through optical projection. Moreover, the slicing mechanism 2 is designed so that the height of each cable sheath slice is consistent, thereby reducing the error caused by the different heights of the cable sheath slices.

[0031] See Figures 1-3In other embodiments, the slicing mechanism 2 includes: a mounting frame 21, a clamping member 22, a clamping roller 23, a cutting blade 24, a drive assembly 5, and a conveying assembly 25; the clamping member 22 and the clamping roller 23 are arranged parallel to each other, one end of the clamping roller 23 is rotatably mounted on the mounting frame 21, and one end of the clamping member 22 is slidably mounted on the mounting frame 21 to adjust the distance between the clamping member 22 and the clamping roller 23; the cutting blade 24 is mounted on the side of the clamping member 22 near the clamping roller 23; the drive assembly 5 drives the clamping member 22 to reciprocate and the clamping roller 23 to rotate; the conveying assembly 25 is arranged below the clamping roller 23 and the clamping member 22, and a gap is provided between the conveying assembly 25 and the cutting blade 24.

[0032] In practice, the cable sheath is fitted onto the clamping roller 23. The drive assembly 5 is then activated. First, the drive assembly 5 drives the clamping member 22 to move towards the clamping roller 23, thereby controlling the clamping roller 23 and clamping member 22 to stably clamp the inner and outer sidewalls of the cable sheath, allowing the cutting blade 24 to pierce the cable sheath. At this point, the clamping roller 23 does not rotate. Next, the clamping roller 23 is controlled to rotate, and the clamping roller 23 drives the cable sheath to rotate through friction, thereby cutting the cable sheath with the cutting blade 24. The cut cable sheath slices fall onto the conveying assembly 25. The conveying assembly 25 conveys the cable sheath slices onto the light-transmitting plate 1. After the conveying is completed, the clamping member 22 is controlled to move in the reverse direction, so that the distance between the clamping member 22 and the clamping roller 23 increases. In this way, the cable sheath can be loosened. Under the action of gravity, the lower end of the cable sheath abuts against the conveying assembly 25, so that the gap between the conveying assembly 25 and the cutting blade 24 is the thickness of the cable sheath slice. The above steps are repeated. Since the gap between the conveying assembly 25 and the cutting blade 24 is fixed, the cable sheath can be cut into multiple cable sheath slices of the same height in sequence.

[0033] See Figures 1-3In other embodiments, the drive assembly 5 includes: a slide 51, a reciprocating screw 52, ​​a rotating shaft 53, a nut seat 54, a drive component 55, a first bevel gear 56, a second bevel gear 57, and a locking unit 6; the slide 51 is slidably mounted on the mounting bracket 21; the reciprocating screw 52 is coaxially arranged with the rotating shaft 53, and the reciprocating screw is rotatably mounted on the slide 51, while the rotating shaft 53 is rotatably mounted on the mounting bracket 21; the nut seat 54 is slidably connected to the mounting bracket 21, and the nut seat 54 is mounted on the reciprocating screw 52 via a ball screw nut pair. The nut seat 54 is connected to the clamping member 22 to drive the clamping member 22 to slide; the driving member 55 drives the reciprocating screw 52 to rotate; when the rotating shaft 53 contacts the reciprocating screw 52, ​​the rotating shaft 53 and the reciprocating screw 52 rotate synchronously, and the reciprocating screw 52 is located on the side of the rotating shaft 53 away from the sliding member; the first bevel gear 56 is coaxially fixed on the rotating shaft 53, and the second bevel gear 57 is coaxially fixed on the clamping roller 23, and the first bevel gear 56 and the second bevel gear 57 mesh with each other; the locking unit 6 restricts the slide 51 and the nut seat 54 to have only one sliding.

[0034] In practice, the driving component 55 is a motor; when the driving component 55 is activated, it drives the reciprocating screw 52 to rotate. At this time, the locking unit 6 restricts the sliding of the slide block 51, causing the reciprocating screw 52 to drive the nut seat 54 to move, thereby pulling the sliding component to move. This causes the nut seat 54 to pull the clamping component 22 towards the clamping roller 23, thereby clamping the cable sheath and piercing the cable sheath through the cutting blade 24. Since the reciprocating screw 52 is separated from the rotating shaft 53, the clamping roller 23 does not rotate at this time.

[0035] The locking unit 6 further restricts the sliding of the nut seat 54; under the rotation of the reciprocating screw 52, ​​the reciprocating screw 52 moves toward the rotating shaft 53, so that the reciprocating screw 52 contacts the rotating shaft 53, and the reciprocating screw 52 and the rotating shaft 53 rotate synchronously; the reciprocating screw drives the rotating shaft 53 to rotate, and the rotating shaft 53 drives the clamping roller 23 to rotate in sequence through the first bevel gear 56 and the second bevel gear 57, thus realizing the cutting of the cable sheath and completing the production of the cable sheath slice; since the locking unit 6 restricts the sliding of the nut seat 54, the sliding part does not slide;

[0036] After the nut seat 54 completes one stroke along the length of the reciprocating screw 52, ​​the nut seat 54 begins to slide in the opposite direction relative to the reciprocating screw 52. The nut seat 54 drives the reciprocating screw 52 to move in the opposite direction, causing the reciprocating screw 52 to separate from the rotating shaft 53. After the reciprocating screw 52 separates from the rotating shaft 53, the sliding of the slide block 51 is restricted by the locking component. Thus, under the rotation of the reciprocating screw 52, ​​the nut seat 54 can be driven to slide in the opposite direction, which in turn drives the clamping member 22 to slide in the opposite direction, thereby stopping the clamping of the cable sheath. Under the action of gravity, the lower end of the cable sheath abuts against the conveying component 25. In this way, the next cable sheath slice can be cut.

[0037] Therefore, by selectively restricting the locking unit 6, it is possible to select the slide 51 or the nut seat 54 to slide; and by cooperating with the locking assembly and the driving component 55, multiple process steps such as clamping, releasing, piercing, and cutting of the cable sheath can be realized.

[0038] See Figures 1-3 In other embodiments, the locking unit 6 includes: a rack 61, a transmission gear 62, a sprocket 63, a chain 64, and a limiting hook 65; the rack 61, transmission gear 62, sprocket 63, chain 64, and limiting hook 65 are all arranged in a one-to-one correspondence; two transmission gears 62 are rotatably mounted on the mounting bracket 21; each transmission gear 62 is fixed with a limiting hook 65, and the two limiting hooks 65 are arranged in a centrally symmetrical manner; two racks 61 are arranged symmetrically, and the racks 61 mesh with the corresponding transmission gears 62; one rack 61 is fixedly connected to the slide 51, and the other rack 61 is fixedly connected to the nut seat 54; both the slide 51 and the nut seat 54 have limiting grooves, and after the limiting hook 65 rotates to the limiting groove, it restricts the sliding of the corresponding slide 51 or nut seat 54; a sprocket 63 is coaxially fixed on the transmission gear 62, and the two sprockets 63 are connected by the chain 64.

[0039] In practice, the nut seat 54 slides, causing the corresponding rack 61 to move. The rack 61 drives the transmission gear 62 to rotate, and the transmission gear 62 drives another transmission gear 62 to rotate via the sprocket 63 and chain 64. This causes the two limit hooks 65 to rotate, so that one limit hook 65 slides out of the limit groove on the slide block 51, and the other limit hook 65 slides into the limit groove on the nut seat 54. This achieves locking of the nut seat 54 and unlocking of the slide block 51. After the nut seat 54 completes one stroke along the length of the reciprocating screw 52, ​​the nut seat 54 begins to move relative to the reciprocating screw... When lever 52 slides in the reverse direction, slide block 51 drives the corresponding rack 61 to move. The rack 61 drives the transmission gear 62 to rotate, which in turn drives the two limit hooks 65 to rotate in the reverse direction. This locks slide block 51 and unlocks nut seat 54, facilitating the next cable sheath cutting. Thus, by setting the locking unit 6, multiple process steps such as clamping, releasing, piercing, and cutting the cable sheath can be achieved simply by rotating the drive component 55. Furthermore, when slide block 51 and nut seat 54 slide to the corresponding positions, the locking unit 6 can restrict slide block 51 or nut seat 54, greatly reducing the number of operation steps.

[0040] See Figures 1-3In other embodiments, the clamping member 22 includes a clamping plate 221 and a rotating roller 222. The clamping plate 221 is slidably mounted on the mounting frame 21, and the rotating roller 222 is rotatably mounted on the clamping plate 221, with the rotating roller 222 located on the side of the clamping plate 221 closer to the clamping roller 23. In specific implementation, the clamping plate 221 drives the rotating roller 222 to clamp the cable sheath, so that the rotating roller 222 abuts against the cable sheath. When the cable sheath rotates, it can drive the rotating roller 222 to rotate synchronously, thereby reducing the frictional force of the cable sheath in the circumferential direction.

[0041] See Figures 1-3 In other embodiments, the clamping roller 23 is provided with a clearance groove 26 to avoid the cutting blade 24; the clearance groove 26 is provided to ensure that the cutting blade 24 can penetrate the cable sheath.

[0042] See Figures 1-3 In other embodiments, the conveying assembly 25 is a belt conveyor, which facilitates the contact and conveying of the lower end of the cable sheath with the conveyor belt. Furthermore, it also includes a hydraulic cylinder 27, with the belt conveyor slidably connected to the mounting frame 21 along the length of the clamping roller 23. The hydraulic cylinder 27 drives the belt conveyor to slide; by driving the belt conveyor to slide via the hydraulic cylinder 27, the loading and unloading of the cable sheath can be achieved.

[0043] See Figures 1-3 In other embodiments, an elastic telescopic member 58 is also included, and the nut seat 54 is connected to the clamping member 22 through the elastic telescopic member 58. By setting the elastic telescopic member 58, it is possible to further adapt to cable sheaths of different thicknesses according to the extension and retraction of the elastic telescopic member 58. Moreover, by extending and retracting the elastic telescopic member 58, interference between the slide 51 and the nut seat 54 during sliding can be effectively avoided.

[0044] See Figures 1-3 In another embodiment, a two-dimensional moving platform 7 is also included, on which the observation and measurement mechanism 4 is mounted. By setting up the two-dimensional moving platform 7, the observation and measurement mechanism 4 can be moved on a two-dimensional plane to perform optical observation and measurement on different cable sheath slices.

[0045] Furthermore, the rotating shaft 53 and the reciprocating screw 52 can also be in contact by a spline sliding method. This spline sliding method can effectively avoid interference when the slide block 51 and the nut seat 54 slide. Furthermore, the end of the reciprocating screw 52 near the rotating shaft 53 is tapered, which can ensure that the spline shaft at the end of the reciprocating screw 52 and the spline groove on the rotating shaft 53 can effectively mesh.

[0046] Working principle and usage process of this invention:

[0047] First, control the hydraulic cylinder 27 to shorten it, which in turn drives the belt conveyor to descend, placing the cable sheath to be cut onto the conveyor belt. Then, control the hydraulic cylinder 27 to extend it, thus placing the cable sheath onto the clamping roller 23 and completing the cable sheath loading operation. By adjusting the extension and retraction length of the hydraulic cylinder 27, the height of the cable sheath slice can be adjusted.

[0048] Then, the drive component 55 is controlled to move, and the drive component 55 drives the reciprocating screw 52 to rotate. At this time, the limit hook 65 is located in the limit groove on the slide 51, thereby limiting the slide 51. The reciprocating screw 52 drives the nut seat 54 to move away from the clamping roller 23. The nut seat 54 pulls the clamping plate 221 to move through the elastic telescopic component 58, so that the rotating roller 222 on the clamping plate 221 abuts against the cable sheath. Through the cooperation of the rotating roller 222 and the clamping roller 23, the cable sheath is clamped stably, and the cutting blade 24 penetrates the cable sheath and extends into the clearance groove 26. This completes the clamping and piercing work of the cable sheath.

[0049] Continue to operate the drive component 55. The drive component 55 drives the reciprocating screw 52 to rotate. The reciprocating screw 52 drives the nut seat 54 to slide. After the nut seat 54 slides to the designated position, the nut seat 54 drives the corresponding rack 61 to mesh with the transmission gear 62. The transmission gear 62 drives another transmission gear 62 to rotate through the sprocket 63 and the chain 64, thereby causing the two limit hooks 65 to rotate. One of the limit hooks 65 slides out of the limit groove on the slide block 51, and the other limit hook 65 slides into the limit groove on the nut seat 54. In this way, the nut seat 54 can be locked and the slide block 51 can be unlocked.

[0050] The drive unit 55 continues to operate, driving the reciprocating screw 52 to rotate. Since the nut seat 54 is locked, the reciprocating screw 52 drives the slide 51 to slide. The slide 51 drives the reciprocating screw 52 to move toward the rotating shaft 53, so that the spline shaft on the reciprocating screw 52 moves into the spline groove on the rotating shaft 53. The reciprocating screw 52 drives the rotating shaft 53 to rotate. The rotating shaft 53 drives the clamping roller 23 to rotate in sequence through the first bevel gear 56 and the second bevel gear 57. In this way, the cable sheath can be cut, and the production of cable sheath slices can be completed.

[0051] Continue to operate the drive component 55. After the drive nut seat 54 completes one stroke along the length of the reciprocating screw 52, ​​the nut seat 54 begins to slide in the opposite direction relative to the reciprocating screw 52. The nut seat 54 drives the reciprocating screw 52 to move in the opposite direction, causing the reciprocating screw 52 to separate from the rotating shaft 53. After the slide 51 slides to the designated position, the slide 51 drives the rack 61 to mesh with the corresponding transmission gear 62. The rack 61 drives the transmission gear 62 to rotate, which in turn drives the two limit hooks 65 to rotate in the opposite direction, thereby locking the slide 51 and unlocking the nut seat 54, so as to facilitate the next cable sheath cutting.

[0052] Continuing the operation of the drive component 55, the rotation of the reciprocating screw 52 causes the nut seat 54 to slide in the opposite direction, which in turn causes the clamping component 22 to slide in the opposite direction, thereby stopping the clamping of the cable sheath. This controls the operation of the belt conveyor, which transports the cut cable sheath slices onto the light-transmitting plate 1. Under the influence of gravity, the lower end of the remaining cable sheath abuts against the conveying assembly 25; thus, the next cable sheath slice can be cut.

[0053] By repeating the above steps, the cable sheath can be cut into multiple cable sheath slices of the same height, thus ensuring that the height of each cable sheath slice is consistent and reducing errors caused by different heights of the cable sheath slices.

[0054] Finally, the actions of the light source 3, the two-dimensional moving platform 7, and the observation and measurement mechanism 4 are controlled so that the light source 3 illuminates the cable sheath slice on the light-transmitting plate 1, enabling the observation and measurement mechanism 4 to observe the projection of the cable sheath slice and measure the projection. In this way, the thickness of the cable sheath can be accurately measured through optical projection.

[0055] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
