Description

Technical Field

[0001] This invention relates to the field of wire harness tensile testing technology, and in particular to a lightweight wire harness research and development testing system. Background Technology

[0002] In the context of the pursuit of extreme weight reduction and high efficiency in industries such as aerospace and new energy vehicles, lightweight wiring harnesses have become a key technological direction. By adopting new polymer materials, nanocomposite materials, and other low-density and high-strength conductors and insulators, the weight of the wiring harness can be effectively reduced, the overall load on the equipment can be lightened, and energy utilization efficiency can be improved. However, the application of new materials may change the mechanical properties of the wiring harness. Tensile testing of lightweight wiring harnesses using tensile testing equipment is an important means to verify the tensile strength and connection reliability of lightweight wiring harnesses when subjected to external forces such as vibration and drag during use. It is a necessary step to ensure that lightweight wiring harnesses using new materials meet the requirements of complex working conditions and ensure the safe and stable operation of equipment.

[0003] Existing wire harness tensile testing devices have the following drawbacks when in use: 1. When connecting and fixing the wire harness to the device, both ends of the wire harness need to be installed and removed on the corresponding clamps. When testing a large number of wire harnesses, the steps are cumbersome and the flexibility is poor. 2. The wire harness needs to be pre-cut to the appropriate length. Existing testing equipment cannot automatically select and position the wire harness of the required length for testing. That is, it cannot accurately position and test the wire harness of the required length directly when the wire harness is not cut, which limits its application scenarios and makes it difficult to meet diverse testing needs, resulting in low practicality.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. Based on the described 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.

[0031] Please refer to Figures 1 to 11 Example 1: This invention proposes a lightweight wire harness R&D and testing system, comprising: a base assembly 1, which includes a mounting base 101, a displacement rod 102, a positioning rod 103, and a displacement motor 104. The displacement rod 102 and the positioning rod 103 are rotatably connected inside the mounting base 101, and the displacement motor 104 is fixedly mounted on the side of the mounting base 101, with the rotating shaft of the displacement motor 104 being drively connected to the displacement rod 102; and a testing assembly, which includes an active mechanism 2 and a passive mechanism 3. The seat assembly 1 also includes a length limiting plate 105, which is inserted into the interior of the mounting base 101, and the displacement seat 201 is located between the lifting clamp 301 and the length limiting plate 105. The active mechanism 2 includes a displacement seat 201, a test push rod 202, and a manual clamp 203. The displacement seat 201 is inserted into the top of the mounting base 101, and the test push rod 202 is fixedly installed on the top of the displacement seat 201. The manual clamp 203 is fixedly installed on one end of the push rod of the test push rod 202. The passive mechanism 3 includes a lifting clamp 301, a lifting rod 302, and a lifting motor 303. The lifting clamp 301 is inserted into the outside of the lifting rod 302, and the lifting rod 302 is rotatably connected to the top of the mounting base 101. The lifting motor 303 is fixedly installed on the side of the mounting base 101, and the shaft of the lifting motor 303 is connected to the bottom of the lifting rod 302 through a gear set. The test components also include a clamping mechanism 4, which includes: The retainer 401, one set of retainers 401 of the clamping mechanism 4 is inserted into the interior of the lifting clamp 301, and the other set of retainers 401 of the clamping mechanism 4 is inserted into the interior of the mounting base 101; The abutting roller 402 is rotatably connected to the retainer 401, and there is resistance when the abutting roller 402 rotates on the retainer 401.

[0032] The displacement rod 102, positioning rod 103, and lifting rod 302 are all threaded rods. The displacement rod 102 is screwed into the displacement seat 201 via a threaded connection, and the positioning rod 103 passes through the displacement seat 201. The lifting rod 302 is screwed into the lifting clamp 301 via a threaded connection. In use, when the test assembly is in the reset state, the lifting clamp 301 is in the raised state. When the displacement motor 104 drives the displacement rod 102 to rotate, the displacement rod 102 can move the displacement seat 201 to change its position via the threaded connection. Thus, when the displacement motor 104 rotates in the forward direction... The displacement seat 201 can move toward the lifting clamp 301 until the manual clamp 203 passes through the bottom of the lifting clamp 301. At this point, after manually fixing one end of the wire harness inside the manual clamp 203, the displacement seat 201 can be moved in the opposite direction by controlling the displacement motor 104 to reverse. This enables the subsequent automatic fixing and positioning of the other end of the wire harness and automatic selection of the required length of wire harness for tensile testing. It is flexible to use, requiring only manual fixing of one end of the wire harness, and the other end of the wire harness will be automatically fixed and positioned, simplifying the operation process and improving work efficiency.

[0033] The displacement seat 201 has a contact sensor 2011 on the side facing the length limiting plate 105. During use, when the displacement seat 201 moves in the opposite direction (away from the lifting clamp 301), it gradually approaches the length limiting plate 105. Under the pulling action of the manual clamp 203, the wire harness passes through the lifting clamp 301, pulling it between the lifting clamp 301 and the manual clamp 203 until the displacement seat 201 contacts the length limiting plate 105. At this point, the distance between the manual clamp 203 and the lifting clamp 301 is equal to the length required for the wire harness test. Therefore, the length of the wire harness pulled between the lifting clamp 301 and the manual clamp 203 is the test length. Afterward, the contact sensor 2011 sends a signal to the control device, which receives the signal from the contact sensor 2011. The power supply to the lifting motor 303 will be turned on to make it rotate forward, while the power supply to the displacement motor 104 will be turned off. When the lifting motor 303 rotates forward, it can drive the lifting rod 302 to rotate through the gear set. When the lifting rod 302 rotates, it can drive the lifting clamp 301 to move downward, thereby fixing the other end of the wire harness to the top of the mounting base 101. Then, by applying tension to the manual clamp 203 through the test push rod 202, the wire harness between the manual clamp 203 and the lifting clamp 301 can be tested for tensile strength. The test is quick and convenient. After the test is completed, by controlling the lifting motor 303 to reverse and drive the lifting clamp 301 to move upward, the fixing and positioning of the wire harness can be released. Then the wire harness on the manual clamp 203 can be removed. After resetting the test component, it can be used to continue to test the tensile strength of subsequent wire harnesses. It is convenient and flexible to use.

[0034] The positioning rod 103 is screwed into the length limiting plate 105 via a threaded rod body, and the displacement rod 102 passes through the length limiting plate 105. During use, the test length value automatically selected by the test component can be freely adjusted. When the positioning rod 103 rotates, it can drive the length limiting plate 105 to move and change its position via the threaded rod body. The change in the position of the length limiting plate 105 changes the contact position between the displacement seat 201 and the length limiting plate 105, which is the position where the contact sensor 2011 is triggered. When the other end of the wire harness is automatically fixed, the distance between the manual clamp 203 and the lifting clamp 301 is the selected wire harness length, which is convenient to adjust and flexible to use.

[0035] The clamping mechanism 4 comprises two sets, respectively located at the top of the mounting base 101 and the bottom of the lifting clamp 301. The two sets of clamping mechanisms 4 are symmetrical. The retainer 401 contains clamping top springs 4011. The two ends of the clamping top springs 4011 of one set of clamping mechanisms 4 are located inside the lifting clamp 301 and the retainer 401, respectively, while the two ends of the clamping top springs 4011 of the other set of clamping mechanisms 4 abut against the inside of the mounting base 101 and the retainer 401, respectively. The end of the manual clamp 203 facing the clamping mechanism 4 has a chamfered design. During use, the clamping mechanism 4 ensures that the wire harness remains straight and taut when pulled by the manual clamp 203, guaranteeing the accuracy of the test results. When the test assembly is in the reset state, the clamping rollers 402 of the two sets of clamping mechanisms 4 are... The chamfered position of the manual clamp 203 abuts and presses against the wire harness, so that the two sets of clamping mechanisms 4 are hidden inside the lifting clamp block 301 and the mounting base 101. This does not hinder the clamping and releasing operation of the manual clamp 203. When the manual clamp 203 moves with the displacement seat 201, the abutting action of the manual clamp 203 eliminates the two sets of clamping mechanisms 4. Thus, under the action of the clamping top spring 4011, the clamping rollers 402 of the two sets of clamping mechanisms 4 will abut against the top and bottom of the wire harness respectively. Since there is a certain resistance when the clamping rollers 402 rotate on the retainer 401, the abutting and pressing action of the two clamping rollers 402 on the wire harness and the rotational resistance of the clamping rollers 402 themselves provide a certain amount of travel resistance when the wire harness is pulled by the manual clamp 203. This allows the wire harness to be in a straight and tight state when pulled, ensuring stable use and accurate testing.

[0036] The manual clamp 203 has a reference pressure sensor 2031 at the bottom of its movable clamping block, and an adaptive pressure sensor 3011 at the bottom of its lifting clamp 301. During use, the reference pressure sensor 2031 and the adaptive pressure sensor 3011 ensure that the clamping force of the lifting clamp 301 on the wire harness is equal to the clamping force of the manual clamp 203. This prevents the wire harness from breaking or being damaged due to excessive clamping force from the lifting clamp 301, thus avoiding testing failure. When the manual clamp 203 clamps and fixes one end of the wire harness, the clamping force is applied manually. Manual operation allows for the application of appropriate clamping force based on the material and specifications of the wire harness. The clamping force applied by the manual clamp 203 can be identified by the reference pressure sensor 2031 and sent to the control device. Thus, when the lifting clamp 301 clamps and fixes the other end of the wire harness, the adaptive pressure sensor 3011 can automatically identify the clamping force of the lifting clamp 301 on the wire harness. When the clamping force of the lifting clamp 301 on the wire harness is equal to the clamping force of the manual clamp 203 on the wire harness, the control device will cut off the power supply of the lifting motor 303 to prevent the lifting clamp 301 from continuing to apply clamping and positioning force to the wire harness. This ensures that the wire harness can be stably clamped and fixed without damage or breakage, further improving the stability of the device.

[0037] The reference pressure sensor 2031, the adaptive pressure sensor 3011, the contact sensor 2011, the displacement motor 104, the lifting motor 303, and the test push rod 202 together form the test system. The test system is electrically connected to an external power supply and control device. Its specific structure and working principle are existing mature technologies and will not be described in detail here.

[0038] The specific usage and function of this embodiment: In this invention, when the test component is in the reset state, the lifting clamp 301 is in the raised state, and when the displacement motor 104 drives the displacement rod 102 to rotate, the displacement rod 102 can drive the displacement seat 201 to move and change its position through the rod thread. Thus, when the displacement motor 104 rotates in the forward direction, the displacement seat 201 can move towards the lifting clamp 301 until the manual clamp 203 passes through the bottom of the lifting clamp 301. At this time, after manually fixing one end of the wire harness inside the manual clamp 203, the displacement seat 201 can be moved in the reverse direction by controlling the displacement motor 104 to reverse, thereby realizing the subsequent automatic fixing and positioning of the other end of the wire harness and automatic selection of the required length. When the wire harness is used for tensile testing, as the displacement seat 201 moves in the opposite direction (away from the lifting clamp 301), the displacement seat 201 gradually approaches the length limiting plate 105. Under the pulling action of the manual clamp 203, the wire harness passes through the lifting clamp 301, causing the wire harness to be pulled between the lifting clamp 301 and the manual clamp 203. The clamping mechanism 4 ensures that the wire harness is always in a straight and taut state when it is pulled by the manual clamp 203, ensuring the accuracy of the test results. When the test component is in the reset state, the clamping rollers 402 of the two sets of clamping mechanisms 4 are pressed against the chamfered position of the manual clamp 203, so that the two sets of clamping mechanisms 4 are hidden inside the lifting clamp 301 and the mounting base 101. The manual clamp 203 will not obstruct the clamping and releasing operation. After the manual clamp 203 moves with the displacement seat 201, the two sets of clamping mechanisms 4 will be eliminated by the clamping action of the manual clamp 203. Thus, under the action of the clamping top spring 4011, the clamping rollers 402 of the two sets of clamping mechanisms 4 will respectively abut against the top and bottom of the wire harness. Since there is a certain resistance when the clamping rollers 402 rotate on the retainer 401, the clamping and squeezing action of the two clamping rollers 402 on the wire harness and the rotational resistance of the clamping rollers 402 themselves provide a certain resistance to the wire harness when it is pulled by the manual clamp 203, so that the wire harness can be straightened and tightened when pulled, until the displacement seat 201 abuts against the length limit plate 105. At this time, the manual clamp 203 will release the clamp. The distance between the movable clamp 203 and the lifting clamp 301 is equal to the length required for the wire harness test. Therefore, the length of the wire harness pulled between the lifting clamp 301 and the manual clamp 203 is the test length. Afterwards, the contact sensor 2011 sends a signal to the control device. Upon receiving the signal from the contact sensor 2011, the control device turns on the power to the lifting motor 303 to make it rotate forward, and simultaneously cuts off the power to the displacement motor 104. When the lifting motor 303 rotates forward, it drives the lifting rod 302 to rotate through the gear set. As the lifting rod 302 rotates, it drives the lifting clamp 301 to move downwards, thereby fixing the other end of the wire harness to the top of the mounting base 101. Then, the test push rod 202 applies a pulling force to the manual clamp 203.This allows for tensile strength testing of wire harnesses positioned between the manual clamp 203 and the lifting clamp 301. The testing is quick and convenient. After the test, the lifting motor 303 is reversed to move the lifting clamp 301 upward, releasing the wire harness from its fixing and positioning function. The wire harness can then be removed from the manual clamp 203. After resetting the testing assembly, it can be used to continue tensile testing on subsequent wire harnesses. The test length value automatically selected by the testing assembly during testing can be freely adjusted. When the positioning rod 103 rotates... The positioning rod 103 can move the length limiting plate 105 to change its position via the rod thread. This change in position alters the contact position between the displacement seat 201 and the length limiting plate 105, which is also the position where the contact sensor 2011 is triggered. When automatically fixing the other end of the wire harness, the distance between the manual clamp 203 and the lifting clamp 301, i.e., the selected wire harness length, is achieved. Through the reference pressure sensor 2031 and the adaptive pressure sensor 3011, the lifting clamp 301 can be aligned with the wire harness... The clamping force of the wire harness is equal to that of the manual clamp 203, avoiding the possibility of wire harness breakage or damage due to excessive clamping force from the lifting clamp 301, which would prevent testing. When the manual clamp 203 clamps and fixes one end of the wire harness, the clamping force is applied manually. Manual operation allows for the application of appropriate clamping force based on the material and specifications of the wire harness. The clamping force applied by the manual clamp 203 can be identified by the reference pressure sensor 2031 and sent to the control unit. The control device automatically identifies the clamping force of the lifting clamp 301 on the wire harness when the lifting clamp 301 clamps and fixes the other end of the wire harness. When the clamping force of the lifting clamp 301 on the wire harness is equal to the clamping force of the manual clamp 203 on the wire harness, the control device will cut off the power to the lifting motor 303 to prevent the lifting clamp 301 from continuing to apply clamping and positioning force to the wire harness, ensuring that the wire harness can be stably clamped and fixed without damage or breakage.
