Description

Technical Field

[0001] The present invention relates to the technical field related to cable copper wire detection, and in particular to a cable copper wire detection platform. Background Art

[0002] Cable copper wire is the core conductive material of wires and cables. Made primarily of high-purity copper (≥99.9%), it possesses excellent electrical and thermal conductivity, ductility, and corrosion resistance, making it widely used in power transmission, communications, electronic equipment, and other fields. Testing cable copper wire is a crucial step in ensuring cable quality and performance, with the elongation of the copper wire being a key indicator of its plastic deformation capacity.

[0003] Regarding the detection of stretching, the existing technology, such as the Chinese patent with publication number CN215448721U, is a wire and cable stretch detection device, comprising a base, the upper surface of which is fixedly connected to a cam frame, the left and right inner walls of the cam frame are provided with guide grooves, the inner walls of the guide grooves are fixedly connected to guide posts, the surfaces of the guide posts are slidably connected to guide sliders, the upper surface of the cam frame is fixedly mounted with a motor, the output end of the motor is fixedly connected to a screw, and the surface of the screw is threadedly connected to a movable block. The wire and cable stretch detection device is provided with a motor, a cam frame, a screw, a movable block, a movable top plate, a fixed bottom plate and a clamping block. When testing the tensile capacity of the cable, the two ends of the cable can be clamped and fixed with the clamping blocks, and then the clamping blocks are driven upward by the motor until the cable is broken. By using a scale, the maximum length of the cable can be measured, thereby realizing the detection of the tensile capacity of the cable.

[0004] The above-mentioned existing technology mainly detects the maximum tensile length of the cable. However, before the cable is stretched, its relaxation degree is not effectively targeted. Cables with different relaxation degrees will also change their stretched lengths after being stretched, thereby affecting subsequent measurement values. When measuring the length of the cable after stretching, it is usually measured with a ruler. The cable needs to be removed and the length is measured one by one to calculate the stretched length. The measurement end points of the removed cable may have position deviations, resulting in inaccurate measurements. Based on this, the present application designs a cable copper wire detection platform. Summary of the Invention

[0036] The following is combined with Figures 1 to 11 This application is described in further detail.

[0037] The embodiment of the present application discloses a cable copper wire detection platform for efficiently detecting the tensile strength (elongation) of cable copper wires.

[0038] Reference Figures 1 to 3As shown, a cable copper wire detection platform disclosed in this embodiment includes a platform 1, a support frame 2, a clamping component 3, a traction component 4, an electric slider 5, a guide frame 6, an electric drive slider 7, a positioning component 8, and a measuring ruler 9. The platform 1 is a fixed foundation, the lower end of the support frame 2 is installed on the platform 1, the clamping component 3 is installed at the upper end of the support frame 2, the upper end of the copper wire is clamped by the clamping component 3, and the traction component 4 is slidably arranged between the electric sliders 5. As a prior art, the electric slider 5 (also called an electric slide, linear module or electric linear slide) is a linear motion mechanism driven by a motor, which is widely used in automation equipment. In order to achieve high-precision, programmable linear displacement control, and achieve millimeter-level or even micron-level repeat positioning accuracy, it is suitable for scenarios that require precise alignment. The electric slider 5 is installed on the inner wall of the support frame 2, and the traction component 4 is used to double-pull down the lower end of the copper wire and eliminate the initial slack. The guide frame 6 is installed between the rear side of the upper end of the support frame 2 and the platform 1. The electric drive slider 7 is slidably set between the guide rail frames 6. A positioning component 8 is installed on the electric drive slider 7. The breaking point of the copper wire is located by the positioning component 8. The measuring ruler 9 is installed at the rear end of the guide rail frame 6. The length of the copper wire after stretching is determined by the cooperation between the positioning component 8 and the measuring ruler 9.

[0039] During the actual operation, the upper and lower ends of the copper wire are clamped and positioned by the clamping assembly 3 and the pulling assembly 4. With the clamping assembly 3 as a fixed point, the lower end of the copper wire is pulled down at a low speed by the pulling assembly 4 until the copper wire breaks, and then the descent is stopped. At this time, with the measuring ruler 9 as the standard, the length of the upper copper wire is recorded by the clamping assembly 3 and the positioning assembly 8 at its corresponding position, and the length of the lower copper wire is recorded by the pulling assembly 4 and the positioning assembly 8 at its corresponding position. The specific calculation is as follows: the data recorded on the upper and lower copper wires are added to obtain the length B after stretching, and the length of the copper wire before stretching is A;

[0040] Calculate the stretch rate:

[0041] The elongation is then obtained and compared with the standard requirements to see whether it meets the requirements.

[0042] Reference Figure 4 As shown, the clamping assembly 3 includes a storage frame 31, the upper end of the storage frame 31 is connected to the upper end of the support frame 2 through a connecting piece, and the clamping units 32 are symmetrically installed on the left and right ends of the storage frame 31. The lower end surface of the storage frame 31 is in the same horizontal plane as the zero scale line of the measuring ruler 9.

[0043] Reference Figure 4As shown, the clamping unit 32 includes a connecting plate 321, and an electric drive push rod 322 is connected between the connecting plate 321 and the side wall of the storage frame 31. Sliding rods 323 are symmetrically installed at the upper and lower ends of the connecting plate 321. The sliding rod 323 is slidably set in the storage cavity opened on the side wall of the storage frame 31. A clamping head 324 is installed at one end of the sliding rod 323 close to the center line position of the storage frame 31. The electric drive push rod 322 is a mechatronic device that converts the rotational motion of the motor into linear push-pull motion, and is widely used in occasions where linear power output is required.

[0044] During the actual positioning process, the upper end of the copper wire is inserted into the storage frame 31 from bottom to top, and the copper wire is clamped by the clamping units 32 arranged on both sides. The specific steps are: the connecting plate 321, the sliding rod 323, and the clamping head 324 are driven to move by the electric drive push rod 322, and the copper wire is clamped by the clamping heads 324 arranged on both sides moving toward each other.

[0045] Reference Figure 5 As shown, the traction assembly 4 includes a connecting frame 41, a sliding plate 42, a pushing unit 43, a positioning member 44, a slack elimination unit 45, a resistance member 46, and a scale pointer 47. The connecting frame 41 is connected to the sliding plate 42 through a support leg. The sliding plate 42 is set between the electric slider 5 for sliding up and down. The pushing unit 43 is installed at the side end of the connecting frame 41, and the pushing unit 43 is arranged symmetrically on the left and right. The inner end of the pushing unit 43 is provided with a positioning member 44 for sliding up and down. The slack elimination unit 45 is set in the middle position of the connecting frame 41. The resistance member 46 that forms resistance friction with the slack elimination unit 45 is installed at the side end of the connecting frame 41. The scale pointer 47 is installed on the rear side of the upper end of the connecting frame 41, and the scale pointer 47 points to the measuring ruler 9.

[0046] During the actual operation, the initial height of the traction component 4 is determined, and the lower end of the copper wire is inserted into the connecting frame 41. The positioning member 44 is driven to move toward each other by the pushing unit 43, and the lower end of the copper wire is clamped and positioned by the positioning member 44. Subsequently, the positioning member 44 in the clamped state is driven to further drop by the slack elimination unit 45, thereby slightly dropping the copper wire, thereby eliminating the initial slack state of the copper wire. At this time, the copper wire is in a taut state. At this time, the scale value of the scale pointer 47 on the measuring ruler 9 is recorded. The scale value is the length of the taut copper wire before it is stretched. Subsequently, the sliding plate 42 and the lower end of the clamped copper wire are pulled down by the electric slider 5 to perform a stretching test on the copper wire.

[0047] Reference Figure 5 As shown, the pushing unit 43 includes an electric push rod 431 , which is mounted on the outer wall of the connecting frame 41 through a cylindrical seat, and a pushing block 432 is mounted on the pushing end of the electric push rod 431 .

[0048] Reference Figure 5 As shown, the positioning member 44 includes an L-shaped member 441, and a slider 442 is installed at the outer end of the L-shaped member 441. The slider 442 is set in the sliding groove opened by the ejection block 432 for sliding up and down. The inner end surface of the L-shaped member 441 is paved with a positioning layer, and the lower end of the L-shaped member 441 is installed with an extrusion frame 443; a drag reducing roller 444 is rolled on the outer side of the lower end of the extrusion frame 443, and the drag reducing roller 444 reduces the difficulty of extrusion. The drag reducing roller 444 contacts the extrusion surface of the extrusion block 445, and the extrusion block 445 is fixedly installed on the inner wall position of the connecting frame 41. The inclined extrusion surface of the extrusion block 445 is a structure that gradually inclines inward from top to bottom, thereby reducing the resistance to extrusion.

[0049] During the actual clamping process, the electric push rod 431 drives the ejection block 432 to move toward each other, and the positioning member 44 connected to the ejection block 432 moves synchronously. The positioning layers arranged on both sides move toward each other to clamp and position the lower end of the copper wire.

[0050] Reference Figure 10 As shown, after the clamping assembly 3 and the traction assembly 4 clamp the upper and lower ends of the copper wire, it may feel loose due to not being tightened, thereby affecting the accuracy of subsequent measurements. The present application further tightens the copper wire with equal tension through the subsequent slack elimination unit 45. If the copper wire is more relaxed, the lower end of the copper wire is pulled into the interior of the connecting frame 41 for a longer length. If the copper wire is close to the tightening degree, the lower end of the copper wire drops less. The specific structure of the slack elimination unit 45 described in the present application is as follows: the slack elimination unit 45 includes a clamping joint 451, a traction frame 452, and a resistance Head 453, sliding column 454, extrusion unit 455, tension spring 456, driving pole 457, the lower end of the card joint 451 is installed on the upper end of the traction frame 452, the left and right ends of the traction frame 452 are symmetrically slidingly provided with resistance heads 453, the sliding column 454 is set inside the traction frame 452 for sliding up and down sliding, the left and right ends of the sliding column 454 are symmetrically provided with extrusion units 455, and a tension spring 456 is connected between the sliding column 454 and the traction frame 452, and the driving pole 457 is installed between the sliding column 454 and the bottom of the connecting frame 41.

[0051] Reference Figure 10 As shown, the outer surface of the resistance head 453 is paved with a rubber layer, the inner surface of the resistance member 46 is paved with a resistance layer, the inner side of the L-shaped resistance head 453 is provided with a chamfered structure, and the extrusion unit 455 includes a triangular block 4551 and a limit plate 4552. The triangular block 4551 is installed on the side wall of the sliding column 454, and the limit plate 4552 is installed on the upper end of the triangular block 4551. The setting of the limit plate 4552 prevents the resistance head 453 from no longer increasing the resistance braking of the resistance member 46 after the triangular block 4551 is separated from the resistance head 453.

[0052] In the actual elimination process, due to the existence of the tension spring 456, the traction frame 452, the sliding column 454, the extrusion unit 455, and the tension spring 456 constitute a simple tension meter. The slack elimination unit 45 has the same force on the copper wire each time it pulls down. The specific steps are as follows: the copper wire is pulled down by the slack elimination unit 45. During the pulling-down process, as the copper wire gradually tightens, the sliding column 454 slides downward relative to the traction frame 452. When the pulling force is greater than the tension of the copper wire, the slack elimination unit 45 will continue to drive the copper wire to pull down. When the pulling force is less than the tension of the copper wire, the sliding column 454 will slide relative to the traction frame 452. The traction frame 452 slides down to the middle area, and the triangular block 4551 connected to the sliding column 454 squeezes the inner side of the resistance head 453 so that the rubber layer of the resistance head 453 contacts the resistance layer of the resistance member 46, thereby making contact. Subsequently, under the condition of resistance braking, the height of the connecting frame 41 remains stationary, but the sliding column 454 will continue to descend until the driving pole 457 drives it to descend to a predetermined height (because the slack elimination unit 45 pulls down different copper wires to different heights, but the driving pole 457 drives the sliding column 454 to descend to a certain height. Therefore, each time the copper wire is pulled down to be taut, the sliding column 454 will still be pulled down to the specified height).

[0053] Reference Figure 6-Figure 8 、 Figure 11 As shown, the existing method for measuring the broken copper wire is to remove the two sections of copper wire and then measure the lengths one by one to calculate the stretched length. There may be a deviation in the position of the end points during the measurement process, which makes the length measurement between the end points and the breaking point inaccurate. The present application detects the breaking point of the copper wire and determines the height through a positioning component 8 that can slide up and down, and then uses the scale pointer 47 and the lower end surface of the storage frame 31 (the same horizontal plane as the zero scale line) as the two end points, and then uses the height recorded by the corresponding positioning component 8 as the end point to record the length of the two sections of copper wire after stretching, and directly detects at the original position, reducing the possibility of inaccuracy. The structure of the positioning component 8 is as follows: the positioning component 8 includes a connecting seat 81, a guide rod 82, a push frame 83, a push rod Component 84, pushing pole 85, peripheral limiting unit 86, conductive unit 87, opening and closing unit 88, scale pointer 2 89, the connecting seat 81 is installed on the electric drive slider 7, the front end of the connecting seat 81 is slidingly provided with a guide rod 82, the front end of the guide rod 82 is fixedly installed on the ejection frame 83, the pushing member 84 is set inside the ejection frame 83 for sliding back and forth, and a pushing pole 85 is connected between the pushing member 84 and the connecting seat 81, the peripheral limiting unit 86 is set inside the ejection frame 83 for sliding left and right, and the peripheral limiting unit 86 is arranged symmetrically on the left and right, the conductive unit 87 is installed at the upper end of the peripheral limiting unit 86, the opening and closing unit 88 used in conjunction with the conductive unit 87 is installed at the upper end of the ejection frame 83, and the scale pointer 2 89 is installed at the rear end of the electric drive slider 7.

[0054] The pusher 84 is pushed forward by the push rod 85 after the breakage of the copper wire, and the pusher 84 is pushed forward by the push rod 85. During the movement, the ejection frame 83 moves forward first (the ejection frame 83 is pushed naturally, and the peripheral limit unit 86 needs to be squeezed and pushed, so the ejection frame 83 moves forward first). When the ejection frame 83 moves to the frontmost position, the peripheral limit units 86 are on both sides of the copper wire, pushing the electric rod 85 to continue to push the pusher 84 forward. The pusher 84 moves relative to the ejection frame 83, and the peripheral limit units 86 are squeezed by the pusher 84 to move toward each other, thereby wrapping the copper wire in a rolling manner around the copper wire (the structure of the copper wire has a certain hardness and toughness. Even if it breaks in the middle, the copper wire of the upper section continues to be suspended under the action of gravity. Although the copper wire of the lower section is bent as a whole, its part close to the connecting frame 41 is still relatively vertical, so that the ejection frame 83 moves to the frontmost position. When in the front position, the peripheral limit units 86 can be located on both sides of the copper wire), and the conductive unit 87 moves synchronously. At this time, the conductive unit 87 is connected to the opening and closing unit 88, and the energized electric drive slider 7 drives the positioning component 8 to rise and fall as a whole (the positioning component 8 corresponding to the position of the clamping component 3 descends, and the positioning component 8 corresponding to the position of the traction component 4 rises). The breaking point of the copper wire is detected by the conductive unit 87. When the conductive unit 87 moves to the breaking point, the conductive unit 87 is displaced again so that the conductive unit 87 is disconnected from the opening and closing unit 88. At this time, the electric drive slider 7 is powered off in time, and the value of the scale pointer 2 89 on the measuring ruler 9 is recorded. The height of the scale pointer 2 89 at the current height is the end height. At this time, the distance between the scale pointer 1 47 and the scale pointer 2 89 and the distance between the lower end surface of the storage frame 31 and the scale pointer 2 89 are the lengths of the two copper wires after stretching.

[0059] During actual operation, the position switching between the conductive unit 87 and the opening and closing unit 88 provided in the present application can control whether the power box 71 is energized. When the power box 71 is in the passage state, the electric drive slider 7 can be driven to move up and down. The specific steps are as follows: when the electric pole 85 is pushed but the pushing member 84 does not move forward, the present application controls the positioning assembly 8 to move up and down to the initial position through the electric drive slider 7. At this time, the contact head 1 881 and the contact head 2 882 are in contact with the conductive member 2 873, thereby forming a passage. When the peripheral limiting units 86 on both sides move toward each other to wrap the copper wire, the conductive member 2 873 is in contact with the conductive member 1 871 under the extrusion of the copper wire. At this time, the contact head 1 881 is in contact with the conductive member 1 871, and the connection is completed. Contact head 2 882 contacts conductive part 2 873, and because conductive part 1 871 and conductive part 2 873 are in contact, a path is formed. When conductive part 1 871 and conductive part 2 873 encounter a breaking point, conductive part 2 873 on both sides is squeezed by the copper wire and is separated from the copper wire. At this time, the breaking point is confirmed, and because the copper wire disappears, conductive part 2 873 on both sides contacts each other under the action of elasticity. At this time, conductive part 1 871 will separate from conductive part 2 873, so that conductive part 2 873 is separated from contact head 2 882, thereby forming a short circuit. The electric drive slider 7 is powered off and stops rising and falling. The value of scale pointer 2 89 on the measuring ruler 9 is recorded. The height of scale pointer 2 89 at the current height is the end height.

Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
