Automobile wire harness stretching test bench

Abstract

The utility model relates to the technical field of tensile testing, and discloses an automobile wire harness tensile test board which comprises a first supporting plate, a second supporting plate, a third supporting plate, optical shafts, limiting plates, springs, universal ball bearings, tension sensors, fixing clamps and driving parts. In the using process, after the two ends of the wire harness are fixed to the two fixing clamps respectively, the driving piece is controlled to work, the second supporting plate and the third supporting plate can move relatively, and therefore the wire harness is stretched in multiple directions. When the wire harness is stretched, the tension sensor can detect the tension borne by the wire harness in real time. Moreover, through the design of the universal ball bearing, the detection direction of the tension sensor can be changed along with the stretching direction of the wire harness, so that the accuracy of the detection result is ensured. Meanwhile, as the spring can be compressed and reset, when the position of the wire harness is changed and the tensile force is suddenly changed, the optical axis can slide relative to the second supporting plate for compensation, so that the wire harness is prevented from suddenly breaking to influence the detection work.

[0018] An embodiment of the present disclosure provides an automotive wiring harness tensile test bench, comprising a first support plate, a second support plate, a third support plate, an optical axis, a stop plate, a spring, a universal ball bearing, a tension sensor, a fixing clamp, and a drive element. The second support plate is positioned above the first support plate. The third support plate is positioned above the first support plate, with the third and second support plates positioned on either side of the first support plate along its length. The first, second, and third support plates are used to support components of the mounting device. The optical axis is slidably disposed through the second support plate along its length and can slide relative to the second support plate along its length. The stop plate is mounted at one end of the optical axis to provide a position limit. The spring is positioned around the optical axis and between the second support plate and the stop plate to provide a spring force. The universal ball bearing's ball seat is connected to the other end of the optical axis, and the universal ball bearing's ball is connected to one end of the tension sensor, enabling the tension sensor to adjust its angle relative to the optical axis.

Furthermore, the design of the universal ball bearing allows the tension sensor's detection direction to change with the direction of the harness's stretching, thereby ensuring the accuracy of the test results. Furthermore, because the spring can be compressed and reset, if the tension acting on the wiring harness changes due to a sudden change in position, the optical axis can slide relative to the second support plate to compensate, preventing the harness from breaking and affecting the smooth progress of the test.

[0036] Combine Figures 1 to 4As shown, an embodiment of the present disclosure provides an automotive wiring harness tensile test bench, comprising a first support plate 10, a second support plate 20, a third support plate 30, an optical axis 40, a limit plate 50, a spring 60, a universal ball bearing 70, a tension sensor 80, a fixing clamp 90, and a driving member 100. The second support plate 20 is located above the first support plate 10. The third support plate 30 is located above the first support plate 10. Along the length direction of the first support plate 10, the third support plate 30 and the second support plate 20 are located on both sides of the first support plate 10. The first support plate 10, the second support plate 20, and the third support plate 30 are used to support the relevant components of the installation equipment. The optical axis 40 is slidably provided on the second support plate 20 along the length direction of the first support plate 10 and can slide relative to the second support plate 20 along the length direction of the first support plate 10. The limit plate 50 is installed at one end of the optical axis 40 to serve as a limit. A spring 60 is mounted on the optical axis 40 and located between the second support plate 20 and the limit plate 50 to provide elastic force. The ball seat of the universal ball bearing 70 is connected to the other end of the optical axis 40, and the ball of the universal ball bearing 70 is connected to one end of the tension sensor 80, allowing the tension sensor 80 to change its angle relative to the optical axis 40. A fixing clamp 90 is mounted on the other end of the tension sensor 80 and the third support plate 30, respectively. The two fixing clamps 90 are used to clamp and secure the two ends of the automotive wiring harness. A driving member 100 is mounted between the first support plate 10 and the second and third support plates 20 and 30 to provide driving force, driving the second and third support plates 20 and 30 to move relative to each other.

[0037] An embodiment of the present disclosure provides an automotive wiring harness tensile test bench. After fixing the two ends of the wiring harness to two fixing clamps 90 respectively, the driving member 100 is controlled to work, so that the second support plate 20 and the third support plate 30 can move relative to each other, thereby stretching the wiring harness in multiple directions. When the wiring harness is stretched, the tension sensor 80 can detect the tension exerted on the wiring harness in real time. Moreover, through the design of the universal ball bearing 70, the detection direction of the tension sensor 80 can be changed with the stretching direction of the wiring harness, thereby ensuring the accuracy of the detection result. At the same time, since the spring 60 can be compressed and reset, when the tension exerted on the wiring harness changes due to a sudden change in the position of the wiring harness, the optical axis 40 can slide relative to the second support plate 20 to compensate, so as to avoid the wiring harness from suddenly breaking and affecting the smooth progress of the detection work.

[0038] Optionally, combined Figure 1 、 Figure 2 and Figure 4As shown, the fixing clamp 90 includes a barrel 91 and a screw 92. The barrel 91 is mounted on the other end of the tension sensor 80 and the third support plate 30, respectively, to support the mounting screw 92. The screw 92 is threadedly connected to the side walls of the two barrels 91, respectively, to abut against the ends of the wiring harness. The centerlines of the two screws 92 are perpendicular to the centerlines of the two barrels 91.

[0039] In the disclosed embodiment, by rotating the two screws 92, the length of the two screws 92 inserted into the two barrels 91 can be changed through the interaction between the threads, thereby tightening or loosening the ends of the wire harness inserted into the two barrels 91. This makes it easy to fix and remove the wire harness.

[0040] Optionally, combined Figure 1 、 Figure 2 and Figure 4 As shown, the fixing clamp 90 further includes a handle 93. The handles 93 are respectively connected to the two screw rods 92 and are respectively located outside the two cylinders 91.

[0043] In the embodiment of the present disclosure, by controlling the operation of the first linear slide 101, the second support plate 20 can be driven to move along the length direction of the first support plate 10, and finally the fixing clamp 90 installed on the tension sensor 80 can be driven to move along the length direction of the first support plate 10 to stretch the wire harness.

[0044] Optionally, combined Figure 1 and Figure 4As shown, the driving member 100 also includes a second linear slide 102, a fourth support plate 103 and a third linear slide 104. The second linear slide 102 is installed on the top surface of the first support plate 10 along the width direction of the first support plate 10, and is used to provide a driving force to realize the linear movement function. The fourth support plate 103 is installed on the moving end of the second linear slide 102, and performs linear motion under the drive of the second linear slide 102. The third linear slide 104 is installed on the fourth support plate 103 along the thickness direction of the first support plate 10, and is used to provide a driving force to realize the linear movement function. Among them, the third support plate 30 is installed on the moving end of the third linear slide 104, and performs linear motion under the drive of the third linear slide 104.

[0045] In the disclosed embodiment, by controlling the operation of the second linear slide 102, the fourth support plate 103 can be driven to move along the width direction of the first support plate 10, and finally the fixing clamp 90 installed on the third support plate 30 can be driven to move along the width direction of the first support plate 10. By controlling the operation of the third linear slide 104, the fixing clamp 90 installed on the third support plate 30 can be driven to move along the thickness direction of the first support plate 10. By the coordinated operation of the second linear slide 102 and the third linear slide 104, the fixing clamp 90 installed on the third support plate 30 can be freely moved in the vertical plane, thereby continuously changing the stretching angle of the wiring harness. This simulates the actual use scenario of the automotive wiring harness, making the test results more meaningful for reference.
