Description
Technical Field
[0001] This utility model relates to the technical field of copper stranded wire processing equipment, and in particular to an adjustable copper stranded wire clamping fixture. Background Technology
[0002] Copper stranded wire is a type of wire made by twisting copper wires together. Copper stranded wire generally has an insulating outer layer. Copper stranded wire is generally distinguished as hard copper stranded wire and soft copper stranded wire. After the copper stranded wire is manufactured, terminals need to be installed at both ends of it so that it can be connected to the circuit.
[0003] When installing terminals on existing copper stranded wires, workers typically hold the copper stranded wire with one hand and use the other hand to slip the terminal onto the end of the wire. Then, they use terminal crimping pliers to tighten the terminal. However, this process requires workers to keep holding the copper stranded wire with one hand and to remove the terminal crimping pliers with the other hand after slipping the terminal. This operation is relatively complicated and inefficient. Furthermore, when installing terminals on the other end of the copper stranded wire, the grip on the wire must be adjusted, making it difficult to install terminals on batches of copper stranded wires.
[0004] Therefore, it is necessary to invent an adjustable copper stranded wire clamping fixture to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide an adjustable copper stranded wire clamping fixture to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable copper stranded wire clamping fixture, including a mounting base, a sliding sleeve fixedly provided on the rear side of the mounting base, a movable plate slidably provided inside the sliding sleeve, a large guide wheel rotatably provided at the bottom front side of the movable plate via a bearing, an extension base fixedly provided at the bottom rear side of the movable plate, movable arms rotatably provided on both sides of the extension base via pins, small guide wheels rotatably provided at the top front sides of the two movable arms via bearings, connecting arms rotatably provided at the top rear sides of the two movable arms via pins, and the top ends of the two connecting arms rotatably provided on the rear side of the mounting base via pins, clamping seats provided at the top sides of the mounting base, and the clamping seats are designed with an "L" shape, with an inner arc surface on the inner side of the clamping seat, and arc grooves adapted to the inner arc surface on both sides of the mounting base, with anti-slip grooves provided on the inner walls of the inner arc surface and the arc grooves.
[0007] Preferably, an extension plate is fixedly provided at the bottom end of the outer side wall of the clamp, and a pressure roller is rotatably provided at the bottom end of the extension plate, with the pressure roller positioned above the small guide roller.
[0008] Preferably, the bottom rear side of the clamp is provided with a support seat that can be rotatably provided by a pin. One end of the support seat is provided with a through hole, and a mounting bolt is provided through the through hole. The top rear side of the mounting seat is provided with two sets of symmetrically distributed screw holes. Each set of screw holes has multiple screw holes, and both sets of screw holes are adapted to the mounting bolt.
[0009] Preferably, a positioning seat is fixedly provided at the top of the movable plate, and sliding holes are provided at both ends of the upper surface of the positioning seat.

[0010] Preferably, a handle is fixedly provided in the middle of the upper surface of the positioning seat.
[0011] Preferably, a support frame is fixedly provided at the center of the rear side of the mounting base.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] 1. This utility model, by setting up a mounting base, a movable plate, a large guide wheel, and small guide wheels, allows the copper stranded wire to be installed with terminals. By pulling the movable plate, the large guide wheel moves upward, causing the two small guide wheels to move outward, thus separating the large and small guide wheels. At this time, the copper stranded wire can be directly placed between the large and small guide wheels. Under the action of the tension spring, the movable plate moves the large and small guide wheels downward, thus clamping and positioning the copper stranded wire. At the same time, during the movement, the small guide wheels press the clamps on both sides of the mounting base, so that the two clamps clamp the two ends of the copper stranded wire to the two sides of the mounting base, thereby clamping the ends of the copper stranded wire. At this time, the operator can complete the positioning of the copper stranded wire without holding it, which facilitates the installation of terminals.
[0014] 2. This utility model, by setting a support base, mounting bolts and screw holes, allows the support base to be installed on the rear side of the mounting base. The support base can support the clamp. By adjusting the position of the mounting bolts to match different screw holes, the installation position of the support base can be adjusted, and thus the distance between the clamp and the mounting base can be adjusted, so that the device can be adapted to copper stranded wires of different diameters.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] This utility model provides, for example Figure 1-4 An adjustable copper stranded wire clamping fixture is shown, including a mounting base 1. A sliding sleeve 2 is fixedly provided on the rear side of the mounting base 1. A movable plate 3 is slidably provided inside the sliding sleeve 2. A large guide wheel 4 is rotatably provided at the bottom front side of the movable plate 3 via a bearing. An extension seat 5 is fixedly provided at the bottom rear side of the movable plate 3. Movable arms 6 are rotatably provided on both sides of the extension seat 5 via pins. Small guide wheels 7 are rotatably provided at the top front side of the two movable arms 6 via bearings. The large guide wheel 4 and the small guide wheel 7 can clamp and fix the copper stranded wire.
[0022] The rear top of each of the two movable arms 6 is rotatably provided with a connecting arm 8 via a pin, and the top of each of the two connecting arms 8 is rotatably provided on the rear side of the mounting base 1 via a pin. The top of each side of the mounting base 1 is provided with a clamp 9, and the clamp 9 is designed with an "L" shape. The "L" shape design makes it convenient for the copper stranded wire to be directly inserted into the clamp 9 from the side without having to be inserted from below, which facilitates the insertion of the copper stranded wire.
[0023] The inner side of the clamp 9 is provided with an inner arc surface 10. Both sides of the mounting base 1 are provided with arc grooves 11 that are adapted to the inner arc surface 10. The inner walls of the inner arc surface 10 and the arc grooves 11 are provided with anti-slip grooves 12. An extension plate 13 is fixedly provided at the bottom of the outer side wall of the clamp 9. A pressure roller 14 is rotatably provided at the bottom of the extension plate 13. The pressure roller 14 is located above the small guide roller 7. The small guide roller 7 can apply pressure to the pressure roller 14 to make it rotate the clamp 9 so that the clamp 9 clamps the copper stranded wire on the outside of the mounting base 1.
[0024] The bottom rear side of the clamp 9 is provided with a support 15 that can be rotatably mounted by a pin. One end of the support 15 has a through hole, and a mounting bolt 16 passes through the through hole. The top rear side of the mounting base 1 has two sets of symmetrically distributed screw holes 17. There are multiple screw holes 17 in each set, and both sets of screw holes 17 are adapted to the mounting bolt 16. The mounting bolt 16 and the screw holes 17 are used to install the support 15.
[0025] The top of the movable plate 3 is fixedly provided with a positioning seat 18. Both ends of the upper surface of the positioning seat 18 are provided with sliding holes, and a sliding rod 19 is slidably provided in the sliding holes. The sliding rod 19 is fixedly provided at the top of the mounting base 1. A tension spring 20 is provided between the positioning seat 18 and the mounting base 1. The tension spring 20 is used to apply a downward force to the positioning seat 18 so that the large guide wheel 4 and the small guide wheel 7 can open and clamp the copper stranded wire.
[0026] A handle 21 is fixedly provided in the middle of the upper surface of the positioning seat 18, and a support frame 22 is fixedly provided in the middle of the rear side of the mounting seat 1. The support frame 22 is used for the stable placement of the device.
[0027] Working principle of this utility model:
[0028] In use, the user can pull the positioning seat 18 upwards via handle 21, causing the positioning seat 18 to move the movable plate 3 upwards. The movable plate 3 then moves the large guide wheel 4 upwards. Simultaneously, the movable plate 3, through the extension seat 5, moves the movable arm 6, which in turn moves the small guide wheel 7 outwards. At this point, a gap is created between the small guide wheel 7 and the large guide wheel 4, and the small guide wheel 7 separates from the pressure roller 14, eliminating the squeezing effect on the clamp 9. Then, the copper stranded wire is placed between the large guide wheel 4 and the small guide wheel 7, with both ends of the wire inserted into the two clamps 9 respectively. Finally, the handle 21 is released, causing the tension spring to move the positioning seat 18 downwards. The seat 18 drives the movable plate 3 and the large guide wheel 4 to move downwards. At the same time, the movable plate 3 drives the small guide wheel 7 to move through the extension seat 5 and the movable arm 6, so that the two small guide wheels 7 move towards the large guide wheel 4. At this time, the small guide wheel 7 can press the copper stranded wire into the outside of the large guide wheel 4. In the final stage of the movement, the small guide wheel 7 squeezes the pressure wheel 14, so that the pressure wheel 14 drives the extension plate 13 and the clamp 9 to move. At this time, the clamp 9 and the mounting seat 1 can clamp and fix the ends of the copper stranded wire. After the two ends of the copper stranded wire are clamped, the large guide wheel 4 is restricted and cannot continue to move. At this time, the installation and fixation of the copper stranded wire can be completed. At this time, the user can install terminals at both ends of the copper stranded wire.
[0029] When the device clamps and fixes copper stranded wires of different diameters, the position of the mounting bolt 16 is adjusted so that it is inserted into different screw holes 17, thereby adjusting the position between the clamp 9 and the mounting base 1. This allows the clamp 9 to clamp copper stranded wires of different diameters on the outside of the mounting base 1, thereby improving the device's adaptability to copper stranded wires of different diameters.
[0030] It should be noted that the support frame 22 in this embodiment is only used to provide support to ensure the stability of the device placement. It includes, but is not limited to, the shape shown in the figure. Vertical or horizontal structures can be selected according to the actual needs of the device. In addition, the diameters of the large guide wheel 4 and the small guide wheel 7 in this embodiment are not limited. When clamping and fixing a longer copper stranded wire, a larger diameter large guide wheel 4 can be selected to ensure that after the copper stranded wire is clamped, its end will not have a long residual part above the mounting base 1, which will affect the installation of the terminal.
[0031] It should be further noted that this embodiment can not only fix the copper stranded wire when installing the terminal block, but is also applicable to other scenarios of processing the ends of the copper stranded wire.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
