[0022] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] See also Figure 1-Figure 5 The utility model provides a technical solution: a tension transmission device, the tension transmission device comprising: a mounting seat 1, a lifting screw tube 2 is arranged on the surface of the mounting seat 1, a lifting screw 3 is screwed inside the lifting screw tube 2, a bearing 4 is arranged at one end of the lifting screw 3, and a base 5 is arranged on the surface of the bearing 4;

[0025] A fixed plate 6, a support rod 7 is arranged in the fixed plate 6, a limit spring 8 and a support frame 9 are sleeved on the surface of the support rod 7, a support shaft 10 is inserted into the support frame 9, and a tensioning wheel 11 is sleeved on the surface of the support shaft 10. A wire harness production equipment includes the tension transmission device;

[0026] When it is necessary to tension wire harnesses of different diameters, the produced wire harnesses can be tensioned using the tensioning wheel 11 first, and then the lifting screw 3 can be moved up or down by rotating the limit nut 13, thereby increasing the tension of the wire harness by the tensioning wheel 11. The tensioning wheel 11 can be used in conjunction with the limit spring 8 to tension the wire harness during production and transportation to avoid loosening during transportation.

[0027] Embodiment 2

[0028] On the basis of the first embodiment, in order to facilitate the tensioning of the wire harness, a tensioning wheel 11 is provided, the support frame 9 can move up and down along the support rod 7, one end of the limit spring 8 is fixedly connected to the end surface of the groove 16, and the other end of the limit spring 8 is fixedly connected to the lower surface of the support frame 9, the tensioning wheel 11 can rotate around the support shaft 10, the fixing plate 6 is fixedly connected to the surface of the base 5, the surface of the fixing plate 6 is provided with a groove 16, and the support rod 7 is fixedly connected to the end surface of the groove 16;

[0029] When in use, the tensioning wheel 11 can be used to tension the wire harness. The tensioning wheel 11 can rotate in conjunction with the support shaft 10, thereby reducing the friction of the tensioning wheel 11 on the wire harness to facilitate tensioning and traction of the wire harness. The setting of the limit spring 8 can make the tensioning wheel 11 have a certain extensibility when in use with the help of the elastic force of the limit spring 8 to avoid hard contact with the wire harness.

[0030] Embodiment 3

[0031] On the basis of the second embodiment, in order to facilitate the tensioning of wire harnesses of different diameters, a lifting screw 3 is provided, the mounting seat 1 can be fixed to the wire harness production equipment by means of positioning bolts, the lifting solenoid 2 is fixedly connected to the surface of the mounting seat 1, a guide plate 12 is provided on the side of the lifting solenoid 2, a limiting nut 13 is fixedly connected to the surface of the lifting screw 3, and one end of the lifting screw 3 is fixedly connected to the inner ring surface of the bearing 4;

[0032] During use, the lifting screw 3 can be rotated conveniently by setting the limit nut 13, so that the height of the lifting screw 3 can be adjusted conveniently, and the intensity of the tensioning force of the tensioning wheel 11 on the wire harness can be adjusted.

[0033] The base 5 is a circular plate-shaped structure, with a positioning plate 14 provided on the side of the base 5, and a limiting rod 15 provided at the bottom of the positioning plate 14. The limiting rod 15 passes through the guide plate 12, and the limiting rod 15 can move up and down in the guide plate 12. The limiting rod 15 is inserted into the guide plate 12 to avoid the problem that the base 5 also rotates when the lifting screw 3 is rotated in cooperation with the bearing 4. The limiting rod 15 is displaced in the guide plate 12 to prevent the base 5 from rotating.

[0034] In actual use, when it is necessary to tension wire harnesses of different diameters, the produced wire harnesses can first be tensioned using the tensioning wheel 11, and then the lifting screw 3 can be moved up or down by rotating the limit nut 13, thereby increasing the tension of the wire harness by the tensioning wheel 11. The tensioning wheel 11 can be conveniently used in conjunction with the limit spring 8 to tension the wire harness during production and transportation to avoid loosening during transportation. This avoids the problem that traditional tensioning equipment is generally welded or fixed to the wire harness production equipment with bolts, which makes it inconvenient to change the tension of the tensioning equipment. When it is necessary to produce wire harnesses of different diameters, the required tension is different, so it is also necessary to replace new tensioning equipment, which not only reduces the practicality of the equipment but also increases the workload of the staff.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
