Description

Technical Field

[0001] The utility model relates to a multi-wire twisting machine. Background Art

[0002] In electronic or electrical engineering, a multi-terminal connecting wire is a commonly used connecting wire harness. Its wire harness is divided into multiple sub-wire harnesses, one end of which shares a plug-in terminal, and the other end of each sub-wire harness is connected to a different sub-plug-in terminal.

[0003] During the processing of multi-terminal connecting wires, each sub-bundle needs to be twisted to twist multiple thin wires together to form a thicker sub-bundle. After the sub-bundles are twisted, the mechanical strength of the sub-bundles can be increased and they are easy to distinguish.

[0004] The existing method of twisting the wire bundle is usually to twist each sub-bundle one by one using a fixture. This twisting method is inefficient and it is easy for the sub-bundles that have not been twisted to be entangled together. It takes a certain amount of time for the operator to straighten out each wire in the untwisted sub-bundle.

[0005] In view of the above problems, it is necessary to research and design a device that can twist wire bundles of various lengths and twist multiple sub-wire bundles at the same time. Utility Model Content

[0006] The purpose of the utility model is to provide a multi-wire stranding machine to solve the above technical problems.

[0007] According to one aspect of the utility model, there is provided a multi-wire stranding machine, comprising:

[0008] A terminal fixing device for fixing the wire harness terminal;

[0009] A plurality of rotating devices, wherein the rotating devices include a driving component and a clamping component, and the driving component drives the clamping component to rotate;

[0010] A plurality of slide rails arranged in parallel, a driving component is disposed on each slide rail, and the position of the driving component on the slide rail can be adjusted; and

[0011] The base, the terminal fixing device and the slide rail are all arranged on the base.

[0012] The multi-wire twisting machine of the present invention, when it is necessary to twist each sub-bundle of a multi-terminal connecting wire, fixes the common plug-in terminal at one end of the multi-terminal connecting wire on the terminal fixing device, and then fixes the plug-in terminal at the other end of each sub-bundle of the wire on different clamping components respectively. Under the action of the driving component, the clamping components that respectively clamp the plug-in terminals at the other end of each sub-bundle of the wire are rotated, and the clamping components and the terminal fixing device can twist the sub-bundles therebetween together. Since there are multiple rotating devices, multiple rotating devices can twist each sub-bundle of the multi-terminal connecting wire at the same time, which can not only improve the twisting efficiency of the bundle, but also avoid the problem of untwisted sub-bundles of wire being entangled together. In addition, according to the length of the sub-bundles in the multi-terminal connecting wire, the position of the driving component on the slide rail can be adjusted, that is, the distance between the clamping component and the terminal fixing device can be adjusted, so that bundles of wires of different lengths can be twisted, thereby improving the versatility of the multi-wire twisting machine.

[0013] Preferably, the terminal fixing device includes a carrying platform, a cylinder and a pressure plate. The carrying platform is arranged on the base, the cylinder is arranged on the side of the carrying platform, and the pressure plate is located above the carrying platform. The cylinder drives the pressure plate to move up and down so that the pressure plate presses the wire bundle terminal on the carrying platform or releases the wire bundle terminal on the carrying platform.

[0014] Therefore, when it is necessary to twist each strand of the multi-terminal connecting wire, the common plug-in terminal at one end of the multi-terminal connecting wire is placed on the carrier, and under the action of the cylinder, the pressure plate moves downward and presses on the common plug-in terminal at one end of the multi-terminal connecting wire. At this time, the common plug-in terminal at one end of the multi-terminal connecting wire can be fixed. After the twisting is completed, under the action of the cylinder, the pressure plate moves upward to loosen the common plug-in terminal at one end of the multi-terminal connecting wire. The fixing and loosening of the common plug-in terminal at one end of the connecting wire are very convenient.

[0015] Preferably, a first elastic pad is provided on the top of the bearing platform, the elastic pad is located below the pressing plate, and a second elastic pad is provided on the bottom of the pressing plate.

[0016] Therefore, when it is necessary to twist each sub-bundle of the multi-terminal connecting wire, the common plug-in terminal at one end of the multi-terminal connecting wire is placed on the first elastic pad on the supporting platform. Under the action of the cylinder, the pressing plate moves downward so that the second elastic pad at the bottom of the pressing plate is pressed onto the common plug-in terminal at one end of the multi-terminal connecting wire. The presence of the first elastic pad and the second elastic pad can prevent the plug-in terminal from being damaged when the pressing plate is pressed on the plug-in terminal.

[0017] Preferably, the rotating device further comprises a slide and a fixing bolt, a slide groove is provided on the slide rail along the length direction, the slide is accommodated in the slide groove, the end of the fixing bolt passes through the slide and is rotated in the inner bottom of the slide groove, and the driving component is arranged on the slide.

[0018] After loosening the fixing bolts, the slide can slide in the slide groove.

[0019] Therefore, when it is necessary to adjust the position of the driving component on the slide rail, loosen the fixing bolts, slide the slide in the slide groove on the slide rail, and the slide drives the driving component to move synchronously on the slide rail to adjust the distance between the clamping component and the terminal fixing device. When the distance between the clamping component and the terminal fixing device is adjusted, tighten the fixing bolts on the slide. The distance adjustment between the clamping component and the terminal fixing device is very convenient.

[0021] One end of the elastic member is arranged on the fixing block, and the other end of the elastic member is arranged on the driving component.

[0022] Therefore, the driving component can slide on the slide table through the slide seat, and when adjusting the distance between the clamping component and the terminal fixing device, it can be slightly larger than the length of the sub-bundle. After fixing the common plug-in terminal at one end of the multi-terminal connecting wire, the driving component and the clamping component are pulled a certain distance toward the terminal fixing device so that the clamping component on the driving component can clamp the plug-in terminal at the other end of the sub-bundle. After the clamping component clamps the plug-in terminal at the other end of the sub-bundle, the driving component is released. Under the elastic force of the elastic member, the driving component will drive the clamping component to always maintain a tendency to slide away from the terminal fixing device. In this way, it can be ensured that the clamping component can straighten the sub-bundle and ensure the twisting quality.

[0023] Preferably, the rotating device further comprises a sliding seat, a fixing block and an elastic member, the sliding seat is slidably arranged on the slide table, the driving component is arranged on the sliding seat, and the fixing block is arranged on the side of the slide table.

[0024] A convex column is arranged on the fixed block, one end of the elastic member is arranged on the side of the slide table, and the other end of the elastic member is arranged on the driving component after bypassing the convex column.

[0025] Therefore, the driving component can slide on the slide table through the slide seat, and when adjusting the distance between the clamping component and the terminal fixing device, it can be slightly larger than the length of the sub-bundle. After fixing the common plug-in terminal at one end of the multi-terminal connecting wire, the driving component and the clamping component are pulled a certain distance toward the terminal fixing device so that the clamping component on the driving component can clamp the plug-in terminal at the other end of the sub-bundle. After the clamping component clamps the plug-in terminal at the other end of the sub-bundle, the driving component is released. Under the elastic force of the elastic member, the driving component will drive the clamping component to always maintain a tendency to slide away from the terminal fixing device. In this way, it can be ensured that the clamping component can straighten the sub-bundle and ensure the twisting quality.

[0026] Preferably, the elastic member is an elastic band or a spring.

[0027] Therefore, under the elastic force of the elastic band and the spring, the driving component will drive the clamping component to always maintain a tendency to slide away from the terminal fixing device, thereby ensuring that the sub-bundle wires always remain in a straight state when twisting the sub-bundle wires.

[0028] Preferably, the clamping component is a spring flat clamp, the driving component is a motor, and one end of the spring flat clamp is arranged on the rotating shaft of the motor.

[0029] Therefore, the plug-in terminal at the other end of the sub-harness can be clamped or released very conveniently by the spring flat clamp, and the motor drives the spring flat clamp to rotate through the rotating shaft to complete the twisting of the sub-harness.

[0030] Preferably, it further comprises a plurality of controllers, wherein the controllers are arranged on the base, one controller is connected to one driving component, and the controller sends a control signal to the driving component.

[0031] Therefore, according to the twisting requirements, the rotation speed and rotation time of the driving component can be set by the controller.

[0032] Preferably, the terminal fixing device is arranged on one of the slide rails, and the position of the terminal fixing device on the slide rail can be adjusted.

[0033] Therefore, according to the length of the sub-bundle in the multi-terminal connecting wire, the position of the terminal fixing device on the slide rail can also be adjusted, so that bundles of longer lengths can be twisted, further improving the versatility of the multi-wire twisting machine.

[0034] Preferably, the number of the rotating devices and the number of the sliding rails are both four.

[0035] Therefore, in this case, the four sub-bundles of the multi-terminal connecting wire can be twisted at the same time, thereby improving the twisting efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The clamping member 22 is a spring flat clamp ( Figure 6As shown), in other embodiments, the clamping component 22 may also be a clamp of other styles, as long as it can clamp the plug-in terminal at the other end of the sub-bundle. The driving component 21 is a motor, and the spring flat clamp can clamp the plug-in terminal at the other end of each sub-bundle. The spring flat clamp can be used to clamp or release the plug-in terminal at the other end of the sub-bundle very conveniently, and the motor drives the spring flat clamp to rotate through the rotating shaft to complete the twisting of the sub-bundle.

[0050] See also Figure 2 and Figure 4 The slide rail 3 is fixed on the base 4. A slide groove 31 is formed on the slide rail 3 along the length direction. The slide 23 is accommodated in the slide groove 31. The end of the fixing bolt 24 passes through the slide 23 and is screwed into the inner bottom of the slide groove 31. In order to avoid interference with the sliding of the slide seat 25, the nut of the fixing bolt 24 is sunk into the slide 23. After loosening the fixing bolt 24, the slide 23 can slide in the slide groove 31, and the slide seat 25 is clamped on the slide 23. The slide seat 25 can The slide 23 can slide on the slide 23. For example, grooves are formed on both sides of the slide 23, and a receiving groove is formed on the slide seat 25. Two opposite inner walls of the receiving groove are formed with protrusions adapted to the grooves. The slide 23 is received in the receiving groove on the slide seat 25, and the two protrusions on the inner wall of the receiving groove of the slide seat 25 are respectively engaged in the grooves on both sides of the slide 23. In this way, it can be ensured that the slide 25 can slide smoothly on the slide 23 and the slide 25 will not fall off the slide 23. Figure 2 The driving component 21 is fixed on the slide 25, and the fixing block 26 is fixed on the side of the slide 23. In this embodiment, a protrusion 261 is formed on the fixing block 26, and one end of the elastic member 27 is fixed on the side of the slide 23 ( Figure 6As shown), the other end of the elastic member 27 is fixed on the driving member 21 after bypassing the boss 261. In other embodiments, the boss 261 may not be provided on the fixing block 26, one end of the elastic member 27 is directly fixed on the fixing block 26, and the other end of the elastic member 27 is fixed on the driving member 21; when it is necessary to adjust the position of the driving member 21 on the slide rail 3, loosen the fixing bolt 24, slide the slide 23 in the slide groove 31 on the slide rail 3, and the slide 23 drives the driving member 21 to move synchronously on the slide rail 3 through the slide seat 25 to adjust the distance between the clamping member 22 and the terminal fixing device 1. When the distance between the clamping member 22 and the terminal fixing device 1 is adjusted, tighten the fixing bolt 24 on the slide 23, and the distance between the clamping member 22 and the terminal fixing device 1 is very convenient to adjust; The driving component 21 can slide on the slide 23 through the slide seat 25.

After the terminal fixing device 1 fixes the common plug-in terminal at one end of the multi-terminal connecting wire, the driving component 21 and the clamping component 22 are pulled a certain distance toward the terminal fixing device 1 so that the clamping component 22 on the driving component 21 can clamp the plug-in terminal at the other end of the sub-bundle. After the clamping component 22 clamps the plug-in terminal at the other end of the sub-bundle, the driving component 21 is released. Under the pulling force of the elastic member 27, the driving component 21 will drive the clamping component 22 to always maintain a tendency to slide away from the terminal fixing device 1. This ensures that the clamping component 22 can straighten the sub-bundle and ensure the twisting quality.

[0051] In this embodiment, the elastic member 27 is an elastic band; in other embodiments, the elastic member 27 may also be a spring. Under the elastic force of the elastic band or the spring, the driving member 21 drives the clamping member 22 to always maintain a tendency to slide away from the terminal fixing device 1, thereby ensuring that the sub-bundle is always kept straight when twisting the sub-bundle.

In other embodiments, the number of rotating devices 2 and slide rails 3 can be adjusted according to the twisting requirements of the wire bundles, as long as one rotating device 2 is installed on one slide rail 3.

[0053] See also Figure 3 and Figure 4 The terminal fixing device 1 can be installed on one of the slide rails 3. The installation method can be: Figure 3 The bottom of the base plate 112 of the carrier 11 can be formed with a boss, which is accommodated in the slide groove 31 on the slide rail 3. The carrier 11 is fixed with bolts, and the end of the bolt passes through the base plate 112 and the boss of the carrier 11 and is screwed into the inner bottom of the slide groove 31. After loosening the bolt, the carrier 11 can slide in the slide groove 31. The position of the terminal fixing device 1 on the slide rail 3 can be adjusted by loosening the bolt. After the position is adjusted, the bolt can be tightened. In this way, the position of the terminal fixing device 1 on the slide rail 3 can also be adjusted according to the length of the sub-bundle in the multi-terminal connecting wire, so that more lengths of bundles can be twisted, further improving the versatility of the multi-wire twisting machine.

[0054] There are multiple controllers 5, and the number of controllers 5 is the same as the number of driving components 21. One controller 5 corresponds to one driving component 21. The controller 5 can be a microcontroller or a single-chip microcomputer. The controller 5 has a touch screen to facilitate setting the speed and rotation time of the driving component 21. Figure 1 In this embodiment, there are four controllers 5, which are all installed on the base 4. One controller 5 is connected to one driving component 21 through a line, and the four controllers 5 are respectively connected to four driving components 21. The controller 5 can send a control signal to the driving component 21. According to the twisting requirements, the rotation speed and rotation time of the corresponding driving component 21 can be set through the controller 5.

[0055] See also Figures 1 to 4The multi-wire stranding machine of the utility model needs to twist each strand of the multi-terminal connecting wire, and takes four strands of the sub-bundle as an example for explanation. According to the twisting requirements, the rotation speed and rotation time of the corresponding driving component 21 can be set by the controller 5. According to the length of the sub-bundle of the multi-terminal connecting wire, the distance between the clamping component 22 and the terminal fixing device 1 can be adjusted first. When adjusting the distance between the clamping component 22 and the terminal fixing device 1, the distance between the two can be made slightly larger than the length of the sub-bundle. When the distance between the clamping component 22 and the terminal fixing device 1 is adjusted, the multi-terminal connecting wire is twisted. The common plug-in terminal at one end of the multi-terminal connecting wire is placed on the first elastic pad 111 on the carrier 11. Under the action of the cylinder 12, the pressing plate 13 moves downward so that the second elastic pad 131 at the bottom of the pressing plate 13 is pressed on the common plug-in terminal at one end of the multi-terminal connecting wire. At this time, the fixing of the common plug-in terminal at one end of the multi-terminal connecting wire is completed. Then, the driving component 21 and the clamping component 22 are pulled toward the terminal fixing device 1 for a certain distance so that the clamping component 22 on the driving component 21 can clamp the plug-in terminal at the other end of the sub-bundle. When the clamping component 22 clamps the plug-in terminal at the other end of the sub-bundle, the driving component 21 is released. The driving component 21, under the pulling force of the elastic member 27, will drive the clamping component 22 to always maintain a tendency to slide away from the terminal fixing device 1, so that it can be ensured that the clamping component 22 can straighten the sub-bundle wires, and the four clamping components 22 are respectively clamped to the plug-in terminal at the other end of one sub-bundle wire in turn, and the plug-in terminal at the other end of the four sub-bundles is fixed at this time. Under the action of the driving component 21, the clamping components 22 that respectively clamp the plug-in terminal at the other end of each sub-bundle wire are rotated, and the clamping component 22 and the terminal fixing device 1 can twist the sub-bundles between the two. Together, since there are four rotating devices 2, the four clamping components 22 can twist the four sub-bundles of the multi-terminal connecting wire at the same time, which can not only improve the twisting efficiency of the bundles, but also avoid the problem of the untwisted sub-bundles being entangled together. In addition, according to the length of the sub-bundles in the multi-terminal connecting wire, the positions of the driving component 21 and the clamping component 22 on the slide rail 3 can be adjusted, and the position of the terminal fixing device 1 on the slide rail 3 can also be adjusted, that is, the distance between the clamping component 22 and the terminal fixing device 1 can be adjusted, so that bundles of wires of different lengths can be twisted, thereby improving the versatility of the multi-wire twisting machine.

[0056] The above are only some embodiments of the present invention, which are intended to illustrate the technical means of the present invention, but not to limit the technical scope of the present invention. Those skilled in the art can make obvious improvements to the present invention in combination with existing common knowledge, which all fall within the protection scope of the present invention.
