Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic wire harness performance testing technology, specifically to an electronic wire harness tensile and torsional force testing device. Background Technology
[0002] As a core connecting component of electronic equipment, the tensile strength and torsional performance of electronic wire harnesses directly affect the reliability of the equipment. Traditional testing devices typically employ manual or semi-automatic structures, fixing both ends of the wire harness with clamps, applying tensile or torsional loads respectively, collecting data using sensors, and displaying the results on instruments.
[0003] Existing electronic wire harness tensile and torsion testing devices mostly use fixed fixtures, which are difficult to adapt to wire harnesses of different diameters and materials. During tensile and torsion testing, it is difficult to fix the wire harness on the center line of the rotating mechanism and the tension mechanism, resulting in errors in the tensile and torsion testing. Furthermore, switching between tensile and torsion testing modes requires manual replacement of fixtures or adjustment of the mechanical structure, which is time-consuming and prone to human error. Therefore, an electronic wire harness tensile and torsion testing device is proposed to solve the above-mentioned problems. Utility Model Content

This technical solution solves the problems mentioned in the background art, such as poor wire harness compatibility, limited testing range, time-consuming operation, and susceptibility to human error, that arise during the electronic wire harness performance testing process.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A torque testing assembly is disposed at the upper end of the operating table and is used to perform tensile tests.
[0009] A tensile testing component, located on the corresponding side of the torque testing component, is used for performing tensile tests;
[0010] The torque testing assembly includes a motor, a torque sensor, a bracket, and a clamping unit. The motor is fixedly mounted on the upper surface of the operating table. The output end of the motor is fixedly connected to one end of the torque sensor. The torque sensor is rotatably mounted inside the bracket. The other end of the torque sensor away from the output end of the motor is connected to a telescopic module. A rotating core is fixedly mounted on the end of the telescopic module away from the torque sensor. The rotating core is rotatably mounted inside the fixed frame. A clamping unit is provided on the end of the rotating core away from the telescopic module.
[0011] Preferably, the tensile testing assembly includes a tensile sensor, a second motor, a gear, a rack, and a clamping unit. A guide rail is fixedly mounted on the upper surface of the fixed base. A rack is slidably connected inside the guide rail. The rack meshes with the gear. The gear is fixedly connected to the output end of the second motor. A tensile sensor is fixedly mounted on the side of the rack near the torque testing assembly. A clamping unit is provided on the side of the tensile sensor away from the rack.
[0012] Preferably, the clamping unit includes a connecting shaft, one end of which is fixedly connected to an adjusting plate, and the other side of the adjusting plate away from the connecting shaft has two horizontal grooves and two vertical grooves.
[0013] Preferably, both the horizontal and vertical grooves are slidably connected to a moving rod.

[0016] Compared with the prior art, this utility model provides an electronic wire harness tensile and torsional force testing device, which has the following beneficial effects:
[0017] This invention utilizes an adjustable clamping unit. When placing the electronic wire harness to be tested, rotating the knob rotates the bidirectional threaded rod. Due to the presence of the threaded rod and the screw holes on the clamping plates, the clamping plate spacing increases, accommodating wire harnesses of different diameters within the length range of the bidirectional threaded rod. After placement, rotating the knob in the opposite direction decreases the clamping plate spacing, achieving the clamping effect. Because the threads of the bidirectional threaded rod extend in opposite directions from the midpoint to both ends, it ensures that the clamped wire harness is centered, preventing mechanically caused errors in tensile and torsional force testing.
[0018] This invention, by simultaneously setting up tensile and torsion testing components, eliminates the need to manually change fixtures or adjust mechanical structures to switch between tensile and torsion testing modes, making operation simple and less prone to human error.

[0028] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0029] Reference Figures 1-3 and Figures 6-7 As shown, an electronic wire harness tensile and torsional testing device includes:
[0030] The control panel 1 has a support leg 2 fixedly installed at its lower end. The control panel 3 is located in the center of the front of the control panel 1. The torque test component is located at the upper end of the control panel 1 and is used to perform tensile tests. The tensile test component is located on the corresponding side of the torque test component and is used to perform tensile tests.
[0031] The torque testing assembly includes a motor 4, a torque sensor 5, a bracket 6, and a clamping unit 10. The motor 4 is fixedly mounted on the upper surface of the operating table 1. The output end of the motor 4 is fixedly connected to one end of the torque sensor 5. The torque sensor 5 is rotatably mounted inside the bracket 6. The other end of the torque sensor 5, away from the output end of the motor 4, is connected to a telescopic module 7. The telescopic module 7 includes an outer shaft section 701 and an inner shaft section 702. The outer shaft section 701 is slidably fitted onto the inner shaft section 702. The mating surface between the inner and outer shaft sections is a rectangular cross-section. During tensile testing, the fixing bracket 9 will slightly shake, thereby preventing the tensile force from being transmitted to the torque sensor. On device 5, since the sleeve cross-section is rectangular, the torque sensor 5 on the side away from motor 4 experiences the same torque as the end of the wire harness. A rotating core 8 is fixedly installed on the end of the telescopic module 7 away from the torque sensor 5. The rotating core 8 is rotatably installed inside the fixed frame 9. A clamping unit 10 is provided on the end of the rotating core 8 away from the telescopic module 7. The clamping units 10 on the torque test assembly and the tensile test assembly clamp both ends of the wire harness respectively. When motor 4 is started, the torque test can begin. The output end of motor 4 acts on the torque sensor 5. The other side of the torque sensor 5 is fixedly connected to the rotating core through the telescopic shaft. The rotating core is fixedly connected to the clamping unit, and the clamping unit drives the wire harness to twist.
[0032] The tensile testing assembly includes a tensile sensor 11, a second motor 13, a gear 14, a rack 15, and a clamping unit 10. A guide rail 16 is fixedly mounted on the upper surface of the fixed base 12. A rack 15 is slidably connected inside the guide rail 16, meshing with the gear 14. The gear 14 is fixedly connected to the output end of the second motor 13. The tensile sensor 11 is fixedly mounted on the side of the rack 15 closest to the torque testing assembly, and the clamping unit 10 is located on the side of the tensile sensor 11 furthest from the rack 15. The two ends of the wire harness are clamped using the torque testing assembly and the clamping unit 10, respectively. Starting the second motor 13 initiates the tensile test. The gear 14 drives the rack 15 to slide within the guide rail 16, and the rack 15 drives the tensile sensor 11. The tensile sensor 11 is fixedly connected to the clamping unit 10, which pulls the wire harness.
[0033] Reference Figures 4-5 As shown, the clamping unit 10 includes a connecting shaft 101. One end of the connecting shaft 101 is fixedly connected to an adjusting plate 102. The other side of the adjusting plate 102 away from the connecting shaft 101 has two horizontal grooves 103 and two vertical grooves 104. Moving rods 105 are slidably connected inside both the horizontal grooves 103 and the vertical grooves 104. A vertical clamping plate 106 is fixedly installed at the end of the moving rod 105 located in the horizontal groove 103 away from the horizontal groove 103. A horizontal clamping plate 107 is fixedly installed at the end of the moving rod 105 located in the vertical groove 104 away from the vertical groove 104. Both ends of the vertical clamping plate 106 and the horizontal clamping plate 107 are threadedly connected to a double-threaded rod 108. Both ends of the double-threaded rod 108 are fixedly installed with knobs 109.
[0034] When placing the electronic wire harness to be tested, rotate knob 109 to rotate the bidirectional threaded rod 108. Due to the presence of the bidirectional threaded rod 108 and the threaded holes on the clamping plates, the clamping plate spacing increases, accommodating wire harnesses of different diameters within the length range of the bidirectional threaded rod. After placement, rotate knob 109 in the opposite direction again to decrease the clamping plate spacing, thus achieving a clamping effect. Because the threads of the bidirectional threaded rod 108 extend in opposite directions from the midpoint to both ends, it ensures that the clamped wire harness is in a centered position, preventing mechanical errors in the tensile and torsional force test.
[0035] Working principle: When using this utility model, first place the electronic wire harness to be tested, rotate the knob 109, and rotate the bidirectional threaded rod 108. Due to the presence of the bidirectional threaded rod 108 and the screw holes on the clamping plate, the clamping plate spacing increases. Within the length range of the bidirectional threaded rod, it can accommodate wire harnesses of different diameters. After placement, rotate the knob 109 in the opposite direction again, and the clamping plate spacing decreases, thus achieving a clamping effect. Because the bidirectional threaded rod 108 extends in opposite directions from the midpoint to both ends, it ensures that the clamped wire harness is centered, preventing mechanical errors in the tension and torque test. The torque test can be started by activating motor 4 using the operation panel 3. The output of motor 4 acts on torque sensor 5, and the other side of torque sensor 5 is fixedly connected to a rotating core via a telescopic shaft. The rotating core is fixedly connected to the clamping unit, which in turn causes the wire harness to twist. The tension test can also be started by activating motor 13 using the operation panel 3. Gear 14 drives rack 15 to slide within guide rail 16, which in turn drives tension sensor 11. Tension sensor 11 is fixedly connected to clamping unit 10, which pulls the wire harness. The tension and torque test requires no manual clamp replacement or mechanical structure adjustment, making operation simple.
