The pressure sensor 7 is fixedly installed on the inner side of the bottom end of the baffle plate 6. The compression detection spring 8 is fixedly connected to the side end of the pressure sensor 7 away from the baffle plate 6. The compression detection disc 9 is fixedly connected to the end of the compression detection spring 8 away from the pressure sensor 7.
[0018] The tensile testing unit 4 includes a testing plate 10, a tensile testing plate 11, a sliding block 12, a second electric push rod 13, a third electric push rod 14, a fixed frame 15, a fixed limiting plate 16, and a compression fixing plate 17. The sliding block 12 is fixedly connected to the bottom front end of the second electric push rod 13. The tensile testing plate 11 is fixedly connected to the bottom end of the sliding block 12. The testing plate 10 is fixedly connected to the outer end of the sliding block 12. The fixed limiting plate 16 is symmetrically arranged on the inner side of the bottom end of the tensile testing plate 11. The fixed frame 15 is fixedly installed on the outer end of the fixed limiting plate 16. The third electric push rod 14 is fixedly installed on the fixed frame 15. The front end of the third electric push rod 14 slides through and is slidably engaged with the fixed limiting plate 16. The compression fixing plate 17 is located on the inner side of the fixed limiting plate 16, and the compression fixing plate 17 is fixedly connected to the front end of the third electric push rod 14.
[0019] A rubber gasket 18 is fixedly installed on the side end of the compression fixing plate 17 away from the fixing limit plate 16, which serves to smooth and fix the plate.
[0020] The second electric push rod 13 is fixedly installed on the track frame plate 2, and the sliding block 12 is slidably engaged on the track frame plate 2. The detection plate 10 is located directly in front of the laser range sensor 1, and the position of the detection plate 10 can be accurately detected by the laser range sensor 1.
[0021] The extrusion test plate 9 is in extrusion contact with the outer end face of the tensile test plate 11, achieving precise positioning of the extrusion test plate 9 before tensile testing.
[0022] Working principle: During use, the device can be fixedly installed using the mounting plate 3. The two ends of the industrial wire harness to be tested are clamped in the symmetrically distributed tensile testing section 4. The ends of the industrial wire harness are fixedly clamped by the symmetrically distributed compression fixing plates 17 and rubber gaskets 18 in the tensile testing section 4. Activating the third electric push rod 14 causes the symmetrically arranged compression fixing plates 17 and rubber gaskets 18 to move synchronously towards the center of the tensile testing plate 11, thereby allowing the symmetrically arranged compression fixing plates 17 and rubber gaskets 18 to clamp the industrial wire harness. The ends of the wire harnesses are clamped and fixed. Depending on the length of the industrial wire harness being tested, the second electric push rod 13 drives the sliding block 12 to slide along the inside of the track frame 2, thereby moving and adjusting the positions of the tensile testing plate 11, the compression fixing plate 17, and the rubber pad 18. This allows the symmetrically distributed tensile testing sections 4 to smoothly clamp and fix the ends of industrial wire harnesses of different lengths using the bottom compression fixing plate 17 and the rubber pad 18. The laser range sensor 1 can detect the distance between itself and the testing plate 10, thus assisting in determining the distance between the two tensile testing sections 4. The distance between the two tensile testing units 4 is precisely adjustable to suit the different lengths of the industrial wire harnesses to be tested. The first electric push rod 5 is activated, causing the baffle plate 6 to slide along the track frame plate 2. This allows the baffle plate 6 to move and adjust in accordance with the tensile testing units 4, ensuring the industrial wire harness is clamped and fixed. At this point, the extrusion testing disc 9 and the tensile testing plate 11 come into contact. The pressure sensor 7 detects the preset pressure value and stops the operation of the first electric push rod 5. Then, the second electric push rods 13 in the two tensile testing units 4 are activated simultaneously, driving the symmetrically arranged... The sliding block 12 slides outward along the track frame plate 2 in sync, so that the symmetrically arranged extrusion fixing plate 17 and tensile detection plate 11 pull the two ends of the industrial wire harness outward in sync. At this time, the tensile detection plate 11 will squeeze the pressure sensor 7 through the extrusion detection disc 9 and the extrusion detection spring 8. When the pressure value detected by the pressure sensor 7 reaches the preset maximum detection pressure value, the second electric push rod 13 stops running. At this time, the industrial wire harness is stretched and straightened. Then, observe whether there is a break on the industrial wire harness, so that the industrial wire harness of different lengths can be quickly tested.
