Description

Technical Field

[0001] This invention relates to the field of wire harness testing technology, specifically a multi-station power line conductivity testing device. Background Technology

[0002] Power cords are electrical wires that transmit current. They consist of three parts: the core wire, the insulation sheath, and the protective outer sheath. Power cord conductivity testing equipment is a professional instrument used to evaluate the conductivity of power cords and ensure that they meet safety standards and usage requirements.

[0003] Currently, when testing electrical wires, the outer casing of the wire needs to be removed. However, during the testing process, the far end of the wire is prone to displacement and short circuits caused by contact with other branches, requiring additional operations to twist the wire cores together. Moreover, existing fixing devices are mostly general-purpose clamps, lacking flexible adjustment capabilities for power cables of different diameters. Each time the test product is changed, a lot of time is spent readjusting the fixing device. This increases the problems of short circuits and crosstalk caused by wire movement during multi-core cable testing, as well as the problem of spending a lot of time adjusting the fixing device. To address these issues, we propose a multi-station power cable conductivity testing device. Summary of the Invention

[0017] The present invention has at least the following beneficial effects:

[0018] 1. Electric actuator one and electric actuator two work together to push push plate two, which drives push rod two to bring cutter two close to the power cord and cut the outer shell. Motor one drives push tube to rotate through gear transmission, so that cutter two can perform circumferential cutting on the power cord. After the outer shell is cut, cutter two returns to the vertical position. Electric actuator one continues to push, and cutter two pulls the outer shell of the power cord to slide away from the circumferential cutting point. This can realize the function of circumferential cutting and peeling of power cords of different diameters.

[0019] 2. Push plate four drives push rod one and push block to move push plate one backward. The guide rod slides in guide groove one, causing push plate one to drive the arranging plate to slide up and down and move closer to each other, so that the branch power lines are staggered and embedded in the inner wall of the arranging plate, making them neatly arranged.

[0020] 3. The electric push rod one pushes the push plate two close to the fixed frame. The push rod two causes the cutter two to squeeze and cut the branch power line shell. The baffle limits the cutting depth. After completion, the push plate one is in the straight section of the guide groove one. The electric push rod one pushes the shell to slide backward away from the wire core.

[0021] 4. Motor 2 drives the guide plate to rotate, controlling the flow direction of waste materials and realizing the sorting and collection of wire shells and branch power cores. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7The present invention provides a technical solution: a multi-station power cord conductivity testing device, including a body 1, a comprehensive testing platform 11, a converter 12 and a socket 13. The comprehensive testing platform 11 and the converter 12 are both located on the upper part of the body 1, and the socket 13 is located on the front part of the body 1. The body 1 is provided with a core cutting part 2 and a shell cutting part 3 for cutting the power cord, and the body 1 is provided with a discharge part 7 for collecting debris.

[0035] The integrated test platform 11 is a comprehensive test platform for multimeters, megohmmeters, clamp meters, and low-voltage power supplies. The converter 12 is used to switch between different test modes, and the socket 13 is a power cord insertion hole.

[0036] The core cutting component 2 includes two push plates 21 that slide inside the machine body 1. A cutter 22 is slidably connected inside the push plate 21. A slide rod 23 is slidably connected inside the two cutters 22 on the side close to each other. An arranging plate 24 is provided on the side of the slide rod 23 away from the push plate 21.

[0037] The push plate 21 can provide internal structural support, the side of the arranging plate 24 that contacts the power line is corrugated, the cutter 22 is a sliding cutting structure, and the slide rod 23 is used to connect the arranging plate 24 and the push plate 21. Through the connection of the slide rod 23, the arranging plate 24 can slide inside the push plate 21.

[0038] Guide rods 28 are provided on both the upper and lower sides of the push plate 21. Multiple guide grooves 281 arranged in a V-shape are provided inside the body 1. The guide rods 28 slide inside the guide grooves 281. The upper and lower edges of the guide grooves 281 are corrugated. Multiple evenly distributed conductive pins 27 are provided on the side of the push plate 21 near the arranging plate 24. The conductive pins 27 penetrate the arranging plate 24.

[0039] The guide rod 28 is used to stabilize and guide the sliding of the push plate 21. The cross-section of the guide groove 281 is a corrugated structure. The V-shaped arrangement can be pushed and slid closer to each other by the guide rod 28 when the two push plates 21 move. The conductive pin 27 can connect to the integrated test platform 11 to provide test support for the wire.

[0040] A limiting plate 221 is provided on the side of the cutter 22 near the push plate 21. A through pipe 232 is provided inside the push plate 21. A limiting block 231 is provided on the side of the slide rod 23 near the push plate 21. Both the limiting block 231 and the limiting plate 221 slide inside the through pipe 232.

[0041] The limiting plate 221 is used to limit the sliding of the tool 22, the limiting block 231 can limit the sliding of the slide rod 23, the through pipe 232 provides the sliding of the limiting block 231 and the limiting plate 221, and can link the sliding of the limiting plate 221 and the limiting block 231. The inside of the through pipe 232 is filled with high-pressure gas.

[0042] Multiple push blocks 25 are slidably connected inside the body 1. A groove 251 is provided at the edge of the push plate 21. The push blocks 25 slide inside the groove 251. A push rod 26 is rotatably connected at the edge of the push blocks 25.

[0043] The slide groove 251 can provide sliding space for the push block 25, which is used to push the push plate 21 to slide, and the push rod 26 can push the push block 25 to slide.

[0044] Drive component 4 drives push rod 26 and push block 25 to slide backward. Push block 25 drives push plate 21 to move backward. When push plate 21 slides, guide rod 28 is pushed by guide groove 281 to slide along a wave shape. This allows push plate 21 to slide up and down. This allows push plate 21 to drive slide rod 23 and arranging plate 24 to slide up and down while sliding closer to each other. When arranging plate 24 presses the internal branch power line, the branch power line can be staggered and embedded in the inner wall of arranging plate 24 by the staggered sliding and rolling movement of the two arranging plates 24. When guide rod 28 slides to the rear side of guide groove 281, the protrusions of the two arranging plates 24 are aligned. As the distance between arranging plates 24 decreases, the branch power line presses the arranging plate 24 to slide closer to push plate 21. This allows multiple branch power lines to be neatly arranged by arranging plate 24.

[0045] The second driving component 5 pushes the two push plates 21 closer together via the push rod 26 and the push block 25. The air inside the tube 232 pushes the cutter 22 to slide out from the inside of the push plate 21. Due to the movement of the arrangement plate 24, the connecting pin 27 can extend from the inside of the arrangement plate 24 and be inserted into the middle of the branch power line. This allows the connecting pin 27 to connect with each branch power line. The second driving component 5 stops moving, and then the converter 12 can be rotated to change different test modes. During the test, the outer shell of the branch does not detach, which can increase the shape stability of the branch power line and prevent the problem of power line series connection caused by line dispersion.

[0046] The shell cutting component 3 includes multiple fixed frames 31 that rotate inside the machine body 1. The front left and right sides of the fixed frame 31 are slidably connected to the second cutter 36. The two cutters 36 are rotatably connected to the opposite side of the two cutters 36, and the rear ends of the two push rods 35 are rotatably connected to the push plate 34.

[0047] The fixed frame 31 is used to support the sliding of the second cutter 36. The second cutter 36 can cooperate with the second push rod 35 and the second push plate 34 to cut the outer sheath of the wire. The second push plate 34 can push the second push rod 35 to move, and the second push rod 35 can push the second cutter 36 to move when rotating.

[0048] A push tube 32 is provided on the rear side of the fixed frame 31. A drive component 4 for driving the push tube 32 to rotate is provided inside the machine body 1. A guide groove 33 is provided at the front end of the fixed frame 31. Guide blocks 331 are provided on both the upper and lower sides of the cutter 36. The guide blocks 331 slide inside the guide groove 33. A drive component 5 for driving the push tube 32 to rotate is provided inside the machine body 1. A blade 361 is provided at the end of the cutter 36 away from the push rod 35. A baffle 362 is provided on the rear side of the blade 361.

[0049] The fixed frame 31 can rotate inside the body 1. The push tube 32 provides rotation support for the fixed frame 31. The guide groove 33 can limit the sliding of the guide block 331. Through the cooperation of the guide block 331 and the guide groove 33, the blade 36 can slide stably. The blade 361 can cut the outer sheath of wires. The baffle 362 is installed on the outer wall of the blade 361 and can limit the cutting depth of the blade 361.

[0050] Driven by the second driving component 5, the second push plate 34 can slide backward. The second push plate 34 drives the two push rods 35 to slide, which in turn drives the two cutters 36 to slide closer to the power cable and cut the outer shell of the power cable. With the cooperation of the first driving component 4, the push tube 32 can be rotated. The push tube 32 drives the cutter 36 to rotate and perform a circumferential cut on the power cable. After the circumferential cut is completed, the first driving component 4 stops working, making the cutter 36 perpendicular to the horizontal plane. This achieves the cutting of the outer shell of the power cable. At this time, the second push plate 34 is located in front of the fixed frame 31. Under the subsequent push of the second driving component 5, The second cutter 36 can pull the outer shell of the power cord forward and slide away from the branch power cord. Under the push of the first electric push rod 51, the second push plate 34 continues to slide closer to the fixed frame 31. The second push plate 34 pushes the second cutter 36 to squeeze and cut the outer shell of the branch power cord through the second push rod 35. When the baffle 362 is pressed against the outer wall of the branch power cord, the second push plate 34 is pressed against the front side of the fixed frame 31, thereby completing the cutting of the outer shell of the branch power cord. At this time, the first push plate 21 slides in the straight section of the first guide groove 281. The operation of the second drive component 5 will push the outer shell of the branch power cord and the outer shell of the power cord to slide backward.

[0051] After the test is completed, the second drive component 5 starts again to pull the shell-cutting component 3 to move backward. The shell-cutting component 3 can push the outer shell of the branch power line and the outer shell of the power line away from the branch power line core. At this time, the second drive component 5 can continue to drive the core-cutting component 2 to move backward. In the straight section of the guide groove 281, the arrangement plate 24 is pushed and squeezed close to the push plate 21, and the cutter 22 is pushed and slid out of the push plate 21. The slid-out cutter 22 can cut the branch power line core.

[0052] Example 2: Please refer to Figure 3 and Figure 4The front of the machine body 1 is provided with multiple electric push rods 61, and locking plates 62 are provided at both ends of the electric push rods 61.

[0053] The electric actuator 61 can push the locking plate 62 to move, and the two locking plates 62 can slide close to each other to clamp and fix the wire.

[0054] Insert the power cord into the socket 13. After the power cord is pressed against the front of the push plate 34, the electric push rod 61 starts to push the two locking plates 62 to slide closer to each other and press against both sides of the power cord. When the pressure of the locking plates 62 pressing against both sides of the power cord reaches the set value, the electric push rod 61 stops fixing the clamping force of the locking plates 62. The movement distance of the locking plates 62 can enable the control platform to identify the diameter of the power cord.

[0055] Example 3: Please refer to Figure 4 and Figure 5 The drive unit 4 includes multiple motors 42 disposed inside the body 1. The drive end of the motor 42 is provided with a gear 43. Multiple gears 41 rotate inside the body 1. Gears 41 and gears 43 mesh with each other. Gears 41 slide on the outer periphery of the push tube 32.

[0056] Motor 42 can drive gear 43 to rotate. Gear 43 and gear 41 work together to drive push tube 32 to rotate. The inner wall of gear 41 is a regular hexagon, which matches the shape of push tube 32. This allows gear 41 to drive push tube 32 to rotate while sliding on the outer periphery of push tube 32.

[0057] Example 4: Please refer to Figure 4 , Figure 5 and Figure 7 The driving component 2 5 includes multiple electric push rods 1 51 disposed inside the body 1. Electric push rod 2 54 is disposed at the front of electric push rod 1 51. Push plate 4 53 is disposed on both the left and right sides of the front of electric push rod 2 54. Push plate 3 52 is slidably connected to the front of electric push rod 1 51. The front end of push plate 4 53 is disposed at the rear side of push plate 3 52. The rear end of push rod 1 26 slides at the edge of push plate 3 52. The rear side of push plate 2 34 is disposed at the front end of electric push rod 1 51.

[0058] Push plate 3 52 slides at the front end of electric push rod 1 51. Electric push rod 2 54 is fixed at the rear side of push plate 3 52 and the front end of electric push rod 1 51. Push plate 4 53 can extend and retract to adjust the distance between push plate 3 52 and electric push rod 2 54. The front end of electric push rod 1 51 rotates at the rear side of push plate 2 34, allowing push plate 2 34 to rotate independently while electric push rod 1 51 pushes push plate 2 34 to move.

[0059] Start pushing the push plate 3 52 to slide, adjust the distance between the electric push rod 2 54 and the push plate 3 52, start the electric push rod 1 51 to push the electric push rod 2 54, push plate 3 52 and push plate 2 34 to slide backward, push plate 2 34 drives the two push rods 2 35 to slide, and drives the two cutters 2 36 to slide closer to the power line.

[0060] Example 5: Please refer to Figure 1 , Figure 2 and Figure 8 The discharge component 7 includes multiple evenly distributed herringbone channels 71 inside the machine body 1. A second motor 72 is provided on the rear side of the herringbone channel 71. A guide plate 73 is rotatably connected inside the herringbone channel 71. The lower part of the guide plate 73 is provided at the drive end of the second motor 72. Multiple collection boxes 74 are slidably connected to the lower part of the machine body 1. The collection boxes 74 abut against the lower end of the herringbone channel 71.

[0061] The herringbone channel 71 is a hollow channel in the shape of a "human". The guide plate 73 rotates at the bifurcation position of the herringbone channel 71. The motor 72 can rotate to drive the guide plate 73 to slide. The collection box 74 is a collection structure with a partition in the middle. When the cut material passes through the herringbone channel 71, it is diverted to the left and right sides of the herringbone channel 71. This allows different materials to fall into different positions in the collection box 74, realizing the function of material screening and collection.

[0062] Before the wire casing is pushed off, motor 2 72 starts and drives the guide plate 73 to rotate, covering the left side of the inside of the herringbone channel 71. After the wire casing falls off, it can slide along the herringbone channel 71 into the inside of the collection box 74. Then, motor 2 72 rotates in the opposite direction, pushing the guide plate 73 to rotate and cover the right side of the inner wall of the herringbone channel 71. When the branch power core is cut, it can slide along the herringbone channel 71 into the left side of the collection box 74. This can achieve the sorting of waste materials, thereby avoiding the mixing of the core and casing together, which is not conducive to subsequent recycling.

[0063] Pressure sensors and distance sensors are provided on the side of the locking plate 62 and the arranging plate 24 near the power cord, thereby identifying the pressure on the power cord and the movement distance of the locking plate 62 and the arranging plate 24.

[0064] The electric actuator 51 can push back to allow the core cutting part 2 and the shell cutting part 3 to slide back into their original positions.

[0065] Example 6: Please refer to Figure 10 The present invention provides a technical solution: a connecting rod 63 is provided on the rear side of the locking plate 62, the rear end of the connecting rod 63 is slidably connected to the middle of the push rod 26, and the rear end of the push rod 26 has an F-shaped channel.

[0066] The connecting rod 63 is located on the rear side of the locking plate 62. The sliding of the locking plate 62 can drive the connecting rod 63 to move and push the push rod 26 to rotate. When the connecting rod 63 pushes the push rod 26 to rotate, it can release stress by sliding. The "F"-shaped structure at the rear end of the push rod 26 provides different sliding lengths for the push plate 52 at the rear end of the push rod 26. In the longest channel, the response of the core cutting member 2 to the sliding of the shell cutting member 3 can be delayed. Thus, the core cutting member 2 can adapt to the alignment of power lines of different diameters and the cutting of branch power line cores without the use of sensors.
