Wire harness tension test device

Abstract

The utility model discloses a wire harness tension test device which comprises a bottom plate, the top of the bottom plate is fixedly connected with two fixed blocks, a movable block is slidably connected between the two fixed blocks, the top of the bottom plate is fixedly provided with an air cylinder, one end of a movable rod of the air cylinder is fixedly connected with one side of the movable block, and the top of the movable block is fixedly connected with a mounting plate. And two second vertical plates are fixedly connected to the top of the mounting plate. The utility model aims to solve the potential problems that the bearing capacity of the wire harness in different directions cannot be comprehensively evaluated and the wire harness in other directions may be ignored because the traditional wire harness tension test device can only perform a single-direction tension test on the wire harness, and the wire harness generally bears forces from different directions at the same time in reality, so that the wire harness tension test device cannot be used for comprehensively evaluating the bearing capacity of the wire harness in other directions. However, the problem that the test result is greatly different from the actual use condition due to the fact that the complicated working condition cannot be simulated by the traditional single-direction tension test is solved.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1-Figure 4 As shown, in this embodiment, a wire harness tension test device includes a base plate 1, two fixed blocks 8 are fixedly connected to the top of the base plate 1, a movable block 20 is slidably connected between the two fixed blocks 8, a cylinder 7 is fixedly installed on the top of the base plate 1, one end of the movable rod of the cylinder 7 is fixedly connected to one side of the movable block 20, a mounting plate 5 is fixedly connected to the top of the movable block 20, two second vertical plates 11 are fixedly connected to the top of the mounting plate 5, an adjustment component is arranged between the two second vertical plates 11, a fixed plate 3 is fixedly connected to the top of the adjustment component, a winding column 9 is fixedly connected to the top of the fixed plate 3, a limiting component is arranged on the top of the fixed plate 3 and on one side of the winding column 9, a slide groove 21 is opened on the surface of one side of the fixed block 8, a slider 19 is slidably connected inside the slide groove 21, and one side of the slider 19 is fixedly connected to one side of the movable block 20.

[0022] First, one end of the wire harness is wound around the outside of the winding column 9, and then the excess wire ends are placed under the limiting component, and then the limiting component is rotated to limit and fix the wire ends, so that the wire harness can be stably fixed by cooperating with the winding column 9, avoiding the problem of the wire harness falling off during the tension test, thereby increasing the stability of the device, and then the other end of the wire harness is fixed by repeating the same method as above. At this time, the movable rod of the cylinder 7 is started to move to drive the movable block 20 to move and drive the slider 19 to slide inside the slide groove 21, thereby increasing the stability of the movement of the movable block 20. The movement of the movable block 20 drives the installation plate 5 to move and drives one end of the wire harness to start stretching. At this time, the tension in a single direction is tested. At this time, the adjustment component is started to drive the fixing plate 3 to move, so as to synchronously test the tension in different directions of the wire harness. In this way, through the tension test in the front and back and left and right directions, the stability of the wire harness in all directions can be comprehensively evaluated, and the looseness or damage problems that may exist in the wire harness during installation or use can be found, thereby increasing the practicality of the device.

[0023] like Figure 1-Figure 4As shown, the limit assembly includes a threaded rod 13, which is rotatably connected to the top of the fixed plate 3, and a turning handle 17 is fixedly connected to the top of the threaded rod 13. The limit assembly also includes a guide rod 16, which is fixedly connected to the top of the fixed plate 3, and a displacement block 18 is movably sleeved on the outer side of the guide rod 16. A threaded groove is provided inside the side of the displacement block 18 away from the guide rod 16 and is threadedly connected to the outer side of the threaded rod 13. A card slot 15 is provided on the surface of the fixed plate 3, and a resistance block 14 is fixedly connected to the bottom of the displacement block 18.

[0024] When fixing the wiring harness, the wire end is placed inside the slot 15, and then the threaded rod 13 is driven to rotate by turning the handle 17, while the displacement block 18 is driven to move outside the guide rod 16 and the resistance block 14 is driven to move toward the slot 15, thereby the wire end inside the slot 15 is resisted and fixed, thereby avoiding the problem of the wiring harness being detached during the tensile test.

[0025] like Figure 1-Figure 4 As shown, the adjustment component includes a reciprocating screw 12, which is rotatably connected between two second vertical plates 11, wherein a motor 6 is fixedly installed on one side of one of the second vertical plates 11, and one end of the output shaft of the motor 6 is fixedly connected to one end of the reciprocating screw 12. The adjustment component also includes two first vertical plates 4, which are fixedly connected to the top of the mounting plate 5, and a sliding rod 2 is fixedly connected between the two first vertical plates 4. A displacement plate 10 is movably sleeved on the outer side of the sliding rod 2, and a threaded groove is opened inside the displacement plate 10 away from the side of the sliding rod 2 and is threadedly connected to the outer side of the reciprocating screw 12, and the top of the displacement plate 10 is fixedly connected to the bottom of the fixed plate 3.

[0026] When the tension test is performed on the wiring harness in other directions, the reciprocating screw 12 is driven to rotate by starting the output shaft of the motor 6, and the displacement plate 10 is driven to move on the outside of the slide bar 2. Then the displacement plate 10 moves to drive the fixed plate 3 to move and drive one end of the wiring harness to adjust its direction. At this time, the tension of the wiring harness in different directions can be tested by coordinating the movement of the movable block 20, thereby increasing the practicality of the device.

[0027] The utility model provides a wire harness tension test device, and the specific working principle is as follows: first, one end of the wire harness is wound around the outside of the winding column 9, and then the excess wire ends are placed inside the card slot 15, and then the threaded rod 13 is driven to rotate by turning the turning handle 17, and at the same time, the displacement block 18 is driven to move on the outside of the guide rod 16 and at the same time, the resistance block 14 is driven to approach the card slot 15, so that the wire ends inside the card slot 15 are resisted and fixed, thereby avoiding the problem of the wire harness being separated during the tension test, and then, the movable rod of the cylinder 7 is started to move, and the movable block 20 is driven to move and at the same time The slider 19 is driven to slide inside the slide groove 21, thereby increasing the stability of the movement of the movable block 20. The movement of the movable block 20 drives the mounting plate 5 to move and at the same time drives one end of the wiring harness to start stretching. At this time, the tension in a single direction is tested. At this time, the output shaft of the starter motor 6 rotates to drive the reciprocating screw 12 to rotate and at the same time drives the displacement plate 10 to move on the outside of the slide rod 2. Then the displacement plate 10 moves to drive the fixed plate 3 to move and at the same time drives one end of the wiring harness to adjust its direction. At this time, in conjunction with the movement of the movable block 20, the tension in different directions of the wiring harness can be tested, thereby increasing the practicality of the device.
