Description

Technical Field

[0001] The utility model relates to the technical field of fatigue testing, in particular to a wire harness fatigue testing device. Background Art

[0002] The fatigue of the wire harness is caused by the bending or twisting of the wire harness. Therefore, after long-term use, the skin of the wire harness will break or even the wire harness will break, which is likely to cause safety accidents or communication failures. Especially in a low-temperature or ultra-low-temperature environment, the wire harness is more likely to break and damage, resulting in the equipment stopping running, and thus it is likely to cause unnecessary losses. Moreover, in a low-temperature environment, it cannot be repaired in time and needs to wait until the temperature rises before repair, which is troublesome. Therefore, for wire harnesses applied to low-temperature environments, test equipment is needed to detect the torsional fatigue strength and bending fatigue strength of the wire harnesses, so as to reduce the probability of wire harness fatigue and further reduce the probability of repair. Therefore, we propose a wire harness fatigue testing device to solve the above-mentioned problems. Content of the Utility Model

Embodiment

[0022] Please refer to Figures 1-4, A wire harness fatigue test device, including a fixed bin 1, with two clamping mechanisms symmetrically arranged inside the fixed bin 1; two limiting plates 11 are symmetrically and fixedly installed on the inner side wall of the fixed bin 1, and each limiting plate 11 is slidably connected to the outer side wall of each clamping plate 4. By installing the limiting plates 11, it is convenient to limit the sliding clamping plate 4. The bottom end inside the fixed bin 1 is fixedly installed with a base 12. By installing the base 12, it is convenient to limit the output end of the working cylinder 8.

[0023] Please refer to Figures 1-4 , The clamping mechanism includes a fixed seat 2, which is fixedly installed on the inner side wall of the fixed bin 1. A through hole 3 is opened at the top end of the fixed seat 2. A clamping plate 4 is slidably installed inside the through hole 3. A fixed cylinder 5 is fixedly installed on the outer side wall of the top area of the clamping plate 4. A fixed column 6 is fixedly installed at the top end of the fixed seat 2. The fixed column 6 is located inside the fixed cylinder 5. A screw rod 7 is longitudinally rotatably installed at the top end of the fixed cylinder 5. The screw rod 7 is screwed to the top end of the fixed bin 1. A cylinder 8 is fixedly installed in the middle area of the top end of the fixed bin 1. A pressure gauge 9 is fixedly installed on the outer side wall of the fixed bin 1. The cylinder 8 and the pressure gauge 9 are electrically connected. A maintenance door 10 is rotatably installed on the outer side wall of the fixed bin 1. For this wire harness fatigue test device, the wire harness is initially bundled through the fixed column 6, and the bundled wire harness is pressed and fixed through the fixed cylinder 5 and the clamping plate 4, so that both ends of the wire harness are fixed inside the fixed bin 1. The bottom end of the cylinder 8 presses the wire harness, which is convenient for the anti-fatigue detection operation of the wire harness, increases the probability of wire harness fatigue, reduces the probability of maintenance, and improves the practicability.

[0024] Please refer to Figure 2 , It should also be noted that a pressing plate 13 is fixedly installed at the bottom end of the cylinder 8. By installing the pressing plate 13, it is convenient to perform fatigue tests on the wire harness through the cylinder 8.

[0025] Please refer to Figure 1 , A plurality of support columns 14 are fixedly installed around the bottom end of the fixed bin 1. By installing the support columns 14, it is convenient to support the device.

[0026] Please refer to Figure 1 , An observation window 15 is opened on the outer side wall of the maintenance door 10. By opening the observation window 15, it is convenient for the user to observe the process of wire harness detection inside the fixed bin 1.

[0027] In summary, when the wire harness fatigue test equipment is in use, open the maintenance door 10, tie the two ends of the wire harness to the outer walls of each fixing column 6 respectively, and pass one end of the wire harness through the inside of the through hole 3. Since the screw rod 7 and the fixed bin 1 are screwed, rotating the screw rod 7 will synchronously drive the fixed cylinder 5 and the clamping plate 4 to perform height adjustment operations, so that the inner wall of the fixed cylinder 5 and the wire harness tied to the fixing column 6 are fixed. Through the clamping and fixing operation between the outer wall of the clamping plate 4 and the wire harness inside the through hole 3, the fixing operation of the wire harness is completed. Start the cylinder 8, output power through the bottom end of the cylinder 8, and synchronously drive the pressing plate 13 to press the wire harness. Observe the deformation state of the wire harness through the observation window 15, and observe the pressure value of the power output by the cylinder 8 through the pressure gauge 9, and then the anti-fatigue test of the wire harness can be carried out.
