[0002] The automotive wiring harness is the main network body of the automotive circuit. The automotive wires are all copper multi-core soft wires. Some soft wires are as thin as hair. Several or even dozens of soft copper wires are wrapped in a plastic insulation tube (polyvinyl chloride). They are soft and not easy to break. In the production of the wire harness, the finished wire needs to be wound up by a winding device, and then cut into connecting wires according to the required length. In the process of winding, different types of wire harnesses have different hardnesses, and the winding tension is different during winding, which affects the tightening and winding effect of the wires. In addition, only wires with a fixed conveying speed can be wound, and the winding quality is poor when winding wires with different conveying speeds. Utility Model Content

[0012] Compared with the prior art, the present invention provides an automotive wiring harness winding device with an adjustable tension structure, which has the following beneficial effects:

[0013] 1. The automobile wiring harness winding device with a tension-adjustable structure is used to wind the wire material being transported at a uniform speed. The torque wrench is inserted into the inside of the regulating socket, and then the regulating socket is rotated by the torque wrench. The regulating socket drives the inner shaft column to rotate, and when the inner shaft column rotates, the mounting turntable is rotated. When the inner shaft column rotates, the inner end of the buffer spring is driven to rotate, thereby compressing the buffer spring to produce elastic deformation, and applying a reverse rotational torque to the inner shaft column through the buffer spring. After adjusting the torque to the specified torque through the torque wrench, the wire material is passed between the first buffer sleeve and the second buffer sleeve. The wire rod is wound around the guide roller and the wire is then tightened to the guide roller so that the wire rod can be tightened and the guide roller can move relative to the guide roller, thereby preventing the wire rod from being loosened and the guide roller from moving relative to the guide roller.

[0014] 2. The automotive wire harness winding device with an adjustable tension structure, when winding the wire that cannot be transported at a uniform speed, twists and controls the deformation of the buffer spring sheet, and then passes the newly-produced wire between the first buffer sleeve and the second buffer sleeve, and then drives the mounting turntable, the first buffer sleeve and the second buffer sleeve to rotate by the torsional force of the buffer spring sheet, and winds a part of the wire around the outside of the first buffer sleeve and the second buffer sleeve, and then winds it through the winding roller. When the speed of wire transmission is greater than the speed of winding of the winding roller, the first buffer sleeve and the second buffer sleeve are driven to rotate by the mounting turntable, and the excess wire is wound around the outside of the first buffer sleeve and the second buffer sleeve, so that the wire remains straight. When the wire transmission speed slows down, the wire wound around the outside of the first buffer sleeve and the second buffer sleeve is pulled out, so that the wire can maintain normal winding, thereby improving the quality of wire winding.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 The utility model provides an automobile wire harness winding device with an adjustable tension structure, comprising a base plate 1, a limiting bracket 2 is installed on the left side of the top of the base plate 1, a limiting cross bar 3 for limiting the height of the wire is installed on the rear side wall of the limiting bracket 2, a winding frame 4 is installed on the right side of the top of the base plate 1, a winding motor 5 is installed on the rear side wall of the winding frame 4, a support shaft 6 is rotatably installed on the front side wall of the winding frame 4 through a bearing, the output end of the winding motor 5 is installed with the rear end of the support shaft 6, the front end of the support shaft 6 is sleeved with a connecting sleeve 7, the front end of the connecting sleeve 7 is sleeved on the outside of the winding roller 8, and a blocking disk 9 is installed on the outer wall of the winding roller 8. A tension adjusting device for adjusting the winding tension is provided at the top of the base plate 1 and located between the limiting cross bar 3 and the winding roller 8.

[0022] Furthermore, the tension adjustment device includes a positioning frame 10, a mounting turntable 11, a first buffer roller 12, a first buffer sleeve 13, a second buffer roller 14, a second buffer sleeve 15, a positioning ring 16, an inner shaft column 17, a regulating jack 18 and a buffer spring 19. The positioning frame 10 is installed on the top of the base plate 1, the positioning ring 16 is installed on the top of the positioning frame 10, the mounting turntable 11 is rotatably installed through the bearing and the rear side of the positioning ring 16, and the front side wall of the mounting turntable 11 is installed through a one-way bearing. There is an inner shaft column 17, a regulating socket 18 is installed at the front end of the inner shaft column 17, a buffer spring 19 is installed on the outer wall of the inner shaft column 17, the outer end of the buffer spring 19 is installed on the inner wall of the positioning ring 16, the first buffer roller 12 is installed on the rear side wall of the mounting turntable 11, the first buffer sleeve 13 is installed on the outer wall of the first buffer roller 12 through a bearing, the second buffer roller 14 is installed on the rear side wall of the mounting turntable 11, and the second buffer sleeve 15 is rotatably installed on the outer wall of the second buffer roller 14 through a bearing.

[0023] Furthermore, the first buffer roller 12 and the second buffer roller 14 are installed at a position away from the center of the rear side wall of the mounting turntable 11, and the first buffer roller 12 and the second buffer roller 14 are installed at a straight line position of the same diameter on the surface of the mounting turntable 11. The first buffer roller 12 and the second buffer roller 14 are driven to rotate through the mounting turntable 11, and the excess wire is wound around the outside of the first buffer roller 12 and the second buffer roller 14 by the first buffer sleeve 13 and the second buffer sleeve 15 on the outside of the first buffer roller 12 and the second buffer roller 14, so that the wire remains in a tightened state. When the wire conveying speed is lower than the winding speed, the first buffer sleeve 13 and the second buffer sleeve 15 will be pulled to rotate to discharge the wire wrapped around the outside, thereby being able to adapt to wire winding work with different conveying speeds.

[0024] Furthermore, the inner shaft column 17 can apply a clockwise rotational force to the mounting turntable 11 through a one-way bearing. When a torque wrench is inserted into the regulating socket 18 to drive the inner shaft column 17 to rotate counterclockwise, the inner shaft column 17 will not drive the mounting turntable 11 to rotate counterclockwise. When the inner shaft column 17 rotates clockwise, it will drive the mounting turntable 11 to rotate clockwise.

[0025] Furthermore, the tension adjustment device is installed at an angle, and the wires wound around the outside of the first buffer sleeve 13 and the second buffer sleeve 15 will not be stacked together, but will be wound to both sides along the outside of the first buffer sleeve 13 and the second buffer sleeve 15, preventing entanglement during uniform speed transportation.

[0026] Furthermore, the connecting sleeve 7 can move forward and backward along the outer side of the support shaft 6. An axial slide groove is provided at the end of the winding roller 8, and a clamping head that is engaged with the axial slide groove is provided on the inner wall of the connecting sleeve 7. Through the cooperation of the clamping head and the axial slide groove, the winding roller 8 is driven to rotate through the connecting sleeve 7 when the support shaft 6 rotates. The end of the winding roller 8 is clamped by controlling the two connecting sleeves 7 to move toward the middle. When the winding roller 8 needs to be removed, the connecting sleeves 7 on both sides are controlled to move away from each other forward and backward, and the clamping of the winding roller 8 can be released to remove the winding roller 8.

[0027] When in use, the wire first passes between the two limiting cross bars 3 on the left, passes between the first buffer sleeve 13 and the second buffer sleeve 15, and then is wound with the winding roller 8. When the wire is wound at a uniform speed, a torque wrench is inserted into the inside of the regulating socket 18, and then the regulating socket 18 is rotated by the torque wrench. The regulating socket 18 drives the inner shaft column 17 to rotate. When the inner shaft column 17 rotates counterclockwise, it will not drive the mounting turntable 11 to rotate. When the inner shaft column 17 rotates, it will drive the inner end of the buffer spring piece 19 to rotate, thereby compressing the buffer spring piece 19 to cause elastic deformation, and applying a reverse rotational torque to the inner shaft column 17 through the buffer spring piece 19. After adjusting the torque to the specified torque through the torque wrench, the torque applied to the inner shaft column 17 is released, and then the elastic force of the buffer spring 19 pushes the inner shaft column 17 to rotate in the opposite direction, and the inner shaft column 17 drives the installation turntable 11 to rotate clockwise, and the installation turntable 11 drives the first buffer sleeve 13 and the second buffer sleeve 15 to rotate in the opposite direction through the first buffer roller 12 and the second buffer roller 14, so that the wire between the limiting cross bar 3 and the winding roller 8 is wound around the outside of the first buffer sleeve 13 and the second buffer sleeve 15 and a tension is applied. By controlling the deformation torque of the buffer spring 19 in advance, the tension of the wound wire can be adjusted. When winding, the winding motor 5 drives the support shaft 6 to rotate. The support shaft 6 drives the connecting sleeve 7 to rotate, and the connecting sleeve 7 drives the winding roller 8 to rotate, and the wire is wound by the winding roller 8. The wire wound on the outside of the first buffer sleeve 13 and the second buffer sleeve 15 will drive the first buffer sleeve 13 and the second buffer sleeve 15 to rotate, and then the wire is kept tight under the winding support of the first buffer sleeve 13 and the second buffer sleeve 15, and finally transported to the outside of the winding roller 8 for winding. When the wire that cannot be transported at a uniform speed is wound, the buffer spring piece 19 is twisted and controlled to deform, and then the newly emerged first buffer sleeve 13 and the second buffer sleeve 15 are passed through, and then the torsional force of the buffer spring piece 19 drives the installation turntable 11 and the first buffer The sleeve 13 and the second buffer sleeve 15 rotate, and a part of the wire is wound around the outside of the first buffer sleeve 13 and the second buffer sleeve 15, and then the wire is wound through the winding roller 8. When the wire transmission speed is greater than the winding speed of the winding roller 8, the first buffer sleeve 13 and the second buffer sleeve 15 are driven to rotate by installing the turntable 11, and the excess wire is wound around the outside of the first buffer sleeve 13 and the second buffer sleeve 15, so that the wire remains straight. When the wire transmission speed slows down, the wire wound around the outside of the first buffer sleeve 13 and the second buffer sleeve 15 is pulled out, so that the wire can maintain normal winding work, thereby improving the quality of wire winding.
