Description

Technical Field

[0001] This utility model relates to the field of wire processing and transmission technology, and in particular to a tensioning mechanism for wires. Background Technology

[0002] Currently, in the process of processing electrical wires, it is usually necessary to cut off the ends of the wires and strip the outer casing, and then connect the stripped end to the connector. This process usually requires continuous operation, so the wires need to be fed forward continuously.

[0003] However, in the existing technology, the wire needs to be pulled forward during the processing of the wire end. Since there is no guide for the movement of the wire during the forward pulling process, the wire is prone to breakage or deformation. In addition, friction damage to the outside of the wire is easily caused during the stretching process, which has a certain impact on the processing quality of the wire. Therefore, in order to address the above shortcomings, a wire stretching mechanism is proposed. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a tensioning mechanism for wires, aiming to improve the problems of wires being prone to breakage, deformation, and surface friction damage during the tensioning process in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wire stretching mechanism includes a worktable. A clamping assembly is provided on the top of the worktable for controlling two sets of arc-shaped plates on both sides to clamp wires of different models. The top of the clamping assembly is provided with several arc-shaped plates, and multiple sets of mounting grooves are provided inside the arc-shaped plates. Springs are fixedly connected to the inner side of the multiple sets of mounting grooves, and movable plates are fixedly connected to the outer side of the springs. A sliding groove is fixedly connected to the rear side of the mounting grooves. A movable column is fixedly connected to the outer side of the movable plate, and an arc-shaped plate is fixedly connected to the rear end of the movable column. A stretching assembly is provided on the outer wall of the clamping assembly for guiding the wire to move between the two sets of arc-shaped plates.

[0007] As a further description of the above technical solution:

[0008] The rear side of the second arc-shaped plate is rotatably connected to several ball bearings;

[0009] As a further description of the above technical solution:

[0010] The clamping assembly includes two mounting slots, both of which are located on the top of the workbench. A motor is fixedly connected to the front end of each mounting slot, and a bidirectional threaded rod is fixedly connected to the drive end of the motor. Moving plates are threadedly connected to the front and rear sides of the bidirectional threaded rod, and a connecting plate is fixedly connected to the top of each moving plate.

[0011] As a further description of the above technical solution:

[0012] Guide rods are fixedly connected inside the two mounting slots, and the middle parts of the two movable plates are slidably connected to the outside of the guide rods;

[0013] As a further description of the above technical solution:

[0014] The two sets of arc-shaped plates are respectively installed on the upper surface of the two connecting plates;

[0015] As a further description of the above technical solution:

[0016] The exterior of the movable plate is disposed inside the second mounting groove, and the exterior of the movable column is slidably connected to the interior of the sliding groove.

[0017] As a further description of the above technical solution:

[0018] The stretching assembly includes two mounting brackets, which are respectively mounted on the outer walls of two movable plates. A fixed plate is fixedly connected to the top of each mounting bracket, and a transmission shaft is provided at the top of the fixed plate.

[0019] This utility model has the following beneficial effects:

[0020] In this invention, by starting the motor, the stable clamping and guiding of different types of wires are achieved through the coordinated action of the mounting slot, the bidirectional threaded rod, the movable plate, the connecting plate, and the guide rod. During the stretching process, the wire is always in a precise guiding state, which effectively prevents the wire from breaking or deforming due to excessive tension, greatly improves the product quality after the wire is stretched, and meets the processing needs of wires of different specifications.

[0021] In this invention, the wire passes between two arc-shaped plates, and through the combined action of the mounting groove, spring, movable plate, slide, movable column, arc-shaped plate, and ball bearings, elastic buffering protection is achieved for the wire during stretching. The ball bearing structure significantly reduces friction between the wire and the arc-shaped plate, thereby ensuring the integrity of the wire's exterior during stretching, avoiding friction damage, and further improving the precision and quality of wire processing.

[0027] 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.

[0028] Reference Figures 1-3 The present invention provides an embodiment of a wire stretching mechanism, comprising a workbench 1, a clamping assembly on the top of the workbench 1 for controlling the arc-shaped plates 8 on both sides to clamp wires of different types, a plurality of arc-shaped plates 8 on the top of the clamping assembly, a plurality of mounting grooves 9 inside the plurality of arc-shaped plates 8, a spring 10 fixedly connected to the inner side of the plurality of mounting grooves 9, a movable plate 11 fixedly connected to the outer side of the spring 10, a sliding groove 12 fixedly connected to the rear side of the mounting grooves 9, a movable column 13 fixedly connected to the outer side of the movable plate 11, an arc-shaped plate 14 fixedly connected to the rear end of the movable column 13, and a stretching assembly on the outer wall of the clamping assembly for guiding the wire to move between the two sets of arc-shaped plates 14.

[0029] Several ball bearings 15 are rotatably connected to the rear side of the arc-shaped plate 14;

[0030] The exterior of the movable plate 11 is set inside the mounting groove 2 9, and the exterior of the movable column 13 is slidably connected to the interior of the slide groove 12.

[0031] Specifically, during operation, the wire is first passed through the middle of the two curved plates 14, and then through the middle of the two transmission shafts 18. At this point, the clamping assembly can be activated to wrap the wire. After installation, the stretching assembly can be activated to drive the wire to move between the two curved plates 14. During the stretching process, the wire drives the ball bearing 15 to roll at the upper end of the curved plate 14, thereby reducing the friction between the wire and the curved plate 14. At the same time, during the stretching process, the wire can drive the curved plate 14 to move between the two curved plates 18, thereby driving the movable column 13 to slide inside the slide groove 12. The movement of the movable column 13 inside the slide groove 12 will drive the movable plate 11 to move inside the mounting groove. At the same time, the movable plate 11 will compress the spring 10, causing the spring 10 to generate a rebound force, which acts on the curved plate 14. The curved plate 14 acts on the wire, thereby preventing the wire from breaking or deforming during the stretching process.

[0032] Reference Figures 1-2 The clamping assembly includes two mounting slots 1 and 2. Both mounting slots 1 and 2 are opened on the top of the worktable 1. A motor 3 is fixedly connected to the front end of the interior of the two mounting slots 1 and 2. A bidirectional threaded rod 4 is fixedly connected to the drive end of the motor 3. Movable plates 5 are threadedly connected to the front and rear sides of the bidirectional threaded rod 4. A connecting plate 6 is fixedly connected to the top of the two movable plates 5.

[0033] Guide rods 7 are fixedly connected inside the two mounting slots 2, and the middle parts of the two movable plates 5 are slidably connected to the outside of the guide rods 7;

[0034] Two sets of arc-shaped plates 8 are respectively installed on the upper surfaces of the two connecting plates 6;

[0035] Specifically, when stretching different types of wires, the motor 3 can be started after the wire is placed between two arc-shaped plates 14. The motor 3 drives the bidirectional threaded rod 4 to rotate. The rotation of the bidirectional threaded rod 4 drives the moving plates 5 on both sides to move relative to each other along the guide rod 7, thereby driving the multiple arc-shaped plates 8 at the top of the connecting plate 6 to move relative to each other, so that the arc-shaped plates 14 clamp the outside of the wire.

[0036] Reference Figure 1 The stretching assembly includes two mounting brackets 16, which are respectively mounted on the outer walls of two movable plates 5. A fixed plate 17 is fixedly connected to the top of each mounting bracket 16, and a transmission shaft 18 is provided at the top of the fixed plate 17.

[0037] Specifically, after the wires are installed, the transmission shaft 18 can be started. The rotation of the transmission shaft 18 will cause the wires to move between the two arc-shaped plates 14.

[0038] Working principle: During operation, the wire is first passed through the middle of the two curved plates 14, and then through the middle of the two transmission shafts 18. At this point, the motor 3 can be started. The motor 3 drives the bidirectional threaded rod 4 to rotate. The rotation of the bidirectional threaded rod 4 causes the moving plates 5 on both sides to move relative to each other along the guide rod 7, thereby causing the multiple curved plates 8 at the top of the connecting plate 6 to move relative to each other. This allows the curved plates 14 to clamp the wire. After installation, the transmission shafts 18 can be started. The rotation of the transmission shafts 18 causes the wire to move between the two curved plates 14. During the stretching process, the wire drives the ball bearings 15. Rolling on the upper end of the second arc plate 14 reduces friction between the wire and the second arc plate 14. During the stretching process, the wire can move the second arc plate 14 between the two first arc plates 8, thereby causing the movable column 13 to slide inside the slide groove 12. The movement of the movable column 13 inside the slide groove 12 will cause the movable plate 11 to move inside the mounting groove. At the same time, the movable plate 11 will compress the spring 10, causing the spring 10 to generate a rebound force, which acts on the second arc plate 14. The second arc plate 14 acts on the wire, thereby preventing the wire from breaking or deforming during the stretching process.

[0039] 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.
