DETAILED DESCRIPTION

[0020] The following is only a preferred embodiment of the present invention, and the scope of protection is not limited to this embodiment. All technical solutions under the concept of the present invention should fall within the scope of protection of the present invention. The same parts are represented by the same figure marks. It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the accompanying drawings, and the words "bottom" and "top", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0021] like Figures 1 to 4 As shown, a widely applicable stranding machine includes a base plate 1. The base plate 1 is provided with a power mechanism and a guide rail 2. The guide rail 2 is fixed to the base plate 1. Two fixing rods 3 are provided on the guide rail 2. The guide rail 2 has an inverted T-shaped guide groove. A T-shaped guide block is fixed at the lower end of the fixing rod 3. The fixing rod 3 is fixed to the guide rail 2 through the guide block and is slidably connected to the guide rail 2.

[0022] One of the fixed rods 3 is provided with an end clamp 4, and the other fixed rod 3 is provided with a tail clamp 5. Both the end clamp 4 and the tail clamp 5 are rotatably connected to the corresponding fixed rod 3. Both the end clamp 4 and the tail clamp 5 are provided with a clamping opening for clamping the end of the wire harness. The clamping opening in this design is also designed similar to a T-shaped opening. The terminal fixed on the end or tail of the wire harness is moved from the side of the clamping opening into the clamping opening. The inner wall of the clamping opening clamps the terminal. When the end clamp 4 or the tail clamp 5 rotates, the terminal in the clamping opening rotates accordingly, thereby achieving the twisting of the wire harness.

[0023] One end of each of the end clamps 4 and the tail clamp 5 is fixedly provided with a driven wheel 9. One end of the end clamp 4 passes through the fixed rod 3 and is fixedly connected to the driven wheel 9; one end of the tail clamp 5 passes through the fixed rod 3 and is fixedly connected to the driven wheel 9. To make the rotation of the end clamp 4 and the tail clamp 5 smoother, a bearing can be provided in the fixed rod 3, and the end clamp 4 and the tail clamp 5 are respectively fixedly connected to the inner edge of the bearing.

[0024] The power mechanism includes a motor 6, a rotating rod 7, and two driving wheels 8. The output shaft of the motor 6 is fixedly connected to one end of the rotating rod 7, and the two driving wheels 8 are fixed to the rotating rod 7. The two driving wheels 8 can move along the rotating rod 7, thereby adjusting the position of the two driving wheels 8 so that the positions of the two driving wheels 8 match the positions of the two driven wheels 9. A transmission belt 10 is installed on a pair of corresponding driving wheels 8 and driven wheels 9. The transmission belt 10 is in a taut state. When the driving wheel 8 rotates, it drives the driven wheels 9 to rotate through the transmission belt 10.

[0025] To prevent the transmission belt 10 from slipping when driving the driven pulley 9, teeth are provided on both the driving pulley 8 and the driven pulley 9. The inner surface of the transmission belt 10 is provided with tooth grooves. The teeth and tooth grooves work together to ensure that the transmission belt 10 can stably drive the driven pulley 9. In this design, the teeth are low, so that the tooth grooves are merely recessed into the inner surface of the transmission belt 10 and do not penetrate the transmission belt. The rack and tooth grooves can also be replaced with anti-slip grooves to increase the friction between the driving pulley 8 and the driven pulley 9 and the transmission belt 10.

[0026] The spacing between the two driven wheels 9 is adjusted by two fixing rods 3. Since the fixing rods 3 and the guide rails 2 in this application are both made of metal, and the inverted T-shaped guide groove of the guide rail 2 and the inverted T-shaped guide block at the lower end of the fixing rod 3 are of similar size, under normal circumstances, it is not easy for the guide block to slide between the guide groove. Therefore, it is only necessary to manually adjust the position between the two fixing rods 3, and there is no need to fix the fixing rods 3. The positions of the two fixing rods 3 will not change significantly, and there is no effect on the stranded wire. Therefore, there is no need to fix the positions of the two fixing rods 3 in a fixed manner. If there is a need to fix the position of the fixing rods 3, in addition to using methods such as adding a card block, you can also directly use tape to stick it, which is convenient for removal later.

[0027] The inner diameter of the driving wheel 8 is larger than the diameter of the rotating rod 7, so that the two driving wheels 8 can move along the rotating rod 7. In order to fix the driving wheel 8 and the rotating rod 7, a fixing plug 11 is provided on the driving wheel 8. One end of the fixing plug 11 is tapered, so that the end of the fixing plug 11 can be easily inserted into the inner side of the driving wheel 8. The fixing plug 11 is made of an elastic material with a high friction coefficient, such as rubber, silicone, etc. When the fixing plug 11 is inserted into the space between the inner hole of the driving wheel 8 and the rotating rod 7, the fixing plug 11 will tightly press against the inner hole of the driving wheel 8 and the surface of the rotating rod 7, so that the driving wheel 8 and the rotating rod 7 cannot slide, thereby allowing the rotating rod 7 to drive the driving wheel 8 to rotate.

[0028] Since the overall length of the rotating rod 7 is relatively long, in order to keep the rotating rod 7 horizontal and increase the stability of the rotating rod 7 during rotation, a plurality of bearing seats 12 are provided on the base plate 1. The rotating rod 7 is passed through a plurality of bearing seats 12. The bearing seats 12 are used to ensure smooth rotation of the rotating rod 7.

[0029] The guide rail 2 is also provided with a plurality of vertical rods 13, the lower ends of which are connected to sliders 14, which are slidably connected to the guide rail 2 and are used to adjust the position of the vertical rods 13. The upper ends of the vertical rods 13 are provided with wire clamps 15, which can clamp a certain position of the wire harness so that the wire harness at that position does not rotate, thereby achieving segmented twisting of the wire harness.

[0030] One end of the wire clamp 15 is equipped with a connecting rod 16, which is inserted into a connecting slot at the top of the vertical pole 13. The wire clamp 15 has a wire hole 17, and one end of the wire hole 17 is equipped with an adjustment buckle 18. The adjustment buckle 18 can adjust the size of the wire hole 17 to ensure that the wire harness is clamped tightly. The adjustment buckle 18 in this application is designed in a strip shape and works similarly to a belt, tightening the wire harness by tightening it.

[0031] The vertical rod 13 is hinged to the slider 14 and can be in two states: upright and inverted. In the upright state, the vertical rod 13 is used to fix the wire harness; in the inverted state, the vertical rod 13 is attached to the base plate 1. This design allows the vertical rod 13 to be inverted when it is not in use, preventing it from affecting the wire stranding and making it more convenient to use without having to remove it.

[0032] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
