Abstract
Description
Technical Field
[0001] This invention relates to the field of cable splicing technology, specifically to a splicing device for cable production. Background Technology
[0002] Cables are made of one or more mutually insulated conductors and an outer insulating protective layer. They are wires that transmit electricity or information from one place to another. During the manufacturing process of cables, it is often necessary to connect two cables together due to product requirements or testing needs. There are many ways to connect cables. When connecting copper and aluminum cables, due to the different materials, direct twisting will generate heat during use. If the temperature is too high, it will damage the cable.
[0003] When splicing existing copper and aluminum cables, the front end sheath of the copper and aluminum cables is usually cut open in a ring shape with a cutter to expose the cable wire inside. Then, the cable wire is inserted into a special wire lug cap. Before insertion, the forked end of the cable wire needs to be manually rotated a few times to make it easier to insert into the wire lug cap. Then, the wire lug cap is pressed tightly with wire crimping pliers to make it fit tightly with the cable wire. Finally, the wire lug caps at the two ends of the cable are fixed with bolts and nuts.
[0004] However, in the process of connecting two different materials, operators need to use auxiliary tools, which is complicated and inconvenient.
[0005] Therefore, we propose a splicing device for cable production. Summary of the Invention

[0016] Preferably, the pushing assembly further includes an electric cylinder, which is fixedly connected to the base. Inside the electric cylinder, the end of the pushing rod is fixedly connected to a connecting frame, and both ends of the connecting frame are fixedly connected to round rods, which are rotatably connected to the adjusting rod.
[0017] Preferably, fixed ears are fixedly connected to the upper and lower sides of the first and second movable teeth, respectively.

Detailed Implementation
[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] Please see Figure 1-9 The present invention provides a technical solution: a cable manufacturing docking device, comprising:
[0033] Base 1, on which a wire lug cap 11 for splicing copper and aluminum cables is provided, one side of the wire lug cap 11 is made of copper and the other side is made of aluminum;
[0034] The docking component 2 is disposed on the base 1 and is used to squeeze the wire nose cap 11 from both sides so that its inner wall abuts against the cable.
[0035] The drive component 3 is located on one side of the docking component 2. The drive component 3 is used to drive the docking component 2 to rotate. By inserting the aluminum cable to be connected into the lug cap 11 from the aluminum end, the docking component 2 and the drive component 3 can squeeze the lug cap 11 on the aluminum side. After squeezing, the copper cable is inserted from the other side, and the docking component 2 and the drive component 3 squeeze the lug cap 11 on the aluminum side again. This allows copper and aluminum cables of different materials to be connected. The mechanical automatic squeezing method can complete the cable connection without the need for the user to use auxiliary clamps to squeeze the cable. The operation is convenient, time-saving and labor-saving.
[0036] The docking assembly 2 also includes a roller 21. The roller 21 is circumferentially arrayed with toothed components 22. The roller 21 is symmetrically arranged about the base 1. The two ends of the roller 21 are connected to brackets 23. The brackets 23 are fixedly connected to the base 1 and rotatably connected to the roller 21. By placing the cable to be docked into the cable lug cap 11 and then starting the drive assembly 3, the rollers 21 on both sides can rotate towards each other. The toothed components 22 on the roller 21 drive the cable lug cap 11 to move downward while squeezing its outer wall, making its outer wall concave inward, so that its inner wall fits precisely with the cable, thereby achieving the docking purpose.
[0037] The drive assembly 3 also includes two gears 31, each fixedly connected to the same side of the roller 21. Two gears 32 are located on one side of each gear 31, meshing with the gears 31 on both sides of the roller 21. A rotating rod 33 is fixedly connected inside each gear 32, positioned at the axis of the gear 32. A bevel gear 34 and a bevel gear 35 are fixedly connected to the rotating rod 33. The axes of the bevel gears 34 and 35 coincide with the axis of the gear 32. A rotating bevel gear 36 meshes between the bevel gears 34 and 35, and the rotating bevel gear 36 is connected to the base 1. The rotating connection includes a gear 37 connected to the end of the rotating rod 33 on one side. A motor 38 is installed inside the base 1. A gear 4 39 is fixedly connected to the end of the rotating shaft inside the motor 38. The gear 4 39 meshes with the gear 37. The gear 37 is rotated counterclockwise by the gear 4 39 at the end of the motor 38. This causes the gear 37 to rotate clockwise with the rotating rod 33, which in turn causes the gear 2 32 on one side of the bevel gear 34 to rotate clockwise. This causes the gear 2 32 to rotate counterclockwise on one side of the bevel gear 34. At the same time, since the gears 2 32 are connected by a rotating bevel gear rod 36, the gear 31 on one side of the bevel gear 35 rotates clockwise, which causes the two rollers 21 to rotate towards each other.
[0038] The number of teeth on bevel gear 1 (34) is greater than that on bevel gear 2 (35). The ratio of the number of teeth on bevel gear 1 (34) to that on bevel gear 2 (35) is 2:1. This creates a speed difference between the two rollers 21. When the wire nose cap 11 is squeezed by the toothed assembly 22 on the roller 21, the speed difference between the rollers 21 causes the wire nose cap 11 to rotate as it moves downwards and is squeezed. This increases the squeezing area and makes the connection between the wire nose cap 11 and the cable more precise.
[0039] The tooth assembly 22 also includes a first movable tooth 221 and a second movable tooth 222. The first movable tooth 221 and the second movable tooth 222 are circumferentially spaced about the roller 21. Both the first movable tooth 221 and the second movable tooth 222 are slidably connected to the roller 21. An adjusting rod 223 is provided on the inner wall of the roller 21. A pushing assembly 224 is provided on one side of the adjusting rod 223. The pushing assembly 224, in conjunction with the adjusting rod 223, can adjust the distance between the ends of the first movable tooth 221 and the second movable tooth 222 and the outer wall of the roller 21. A sensor 225 for detecting the color of the wire nose cap 11 is provided on the base 1. The color sensor 225 identifies the color on one side of the wire nose. When it is identified as yellow-red, the wire nose to be extruded is made of aluminum. The first movable tooth 221 moves by the pushing assembly 224 in conjunction with the adjusting rod 223 without external force. The lower part is in a movable state, and the second moving tooth 222 moves forward under the influence of external force, so that the groove marks on the aluminum wire lug after being squeezed are deeper. Since aluminum has good ductility, this method can make its inner wall fit precisely with the aluminum cable. Conversely, when the sensor 225 identifies the wire lug as an aluminum sheet, the wire lug to be squeezed is a copper wire lug. At this time, the pushing component 224 moves in conjunction with the adjusting rod 223, so that the first moving tooth 221 is in a fixed state under external force. At this time, the second moving tooth 222 can return to its initial length when it is not subjected to external force, so that the groove marks on the copper wire lug after being squeezed are shallower. Since copper material has less ductility than aluminum, this method can leave shallower but denser indentations, so that its inner wall fits precisely with the copper cable.
[0040] The front end of the adjusting rod 223 is a locking part 2231, which is slidably connected to the roller 21, facilitating the back-and-forth movement of the adjusting rod 223 within the roller 21. The locking part 2231 is non-circular in shape; it can be elliptical, gear-shaped, triangular, etc. This non-circular design allows the adjusting rod 223 to rotate with the roller 21. The rear end of the adjusting rod 223 is an abutment part 2232. The tails of the first moving tooth 221 and the second moving tooth 222 are inclined, and the tails of the first moving tooth 221 and the second moving tooth 222 are inclined. The tails of the second tooth 222 are tilted in opposite directions, and the abutting part 2232 abuts against the tail of the first tooth 221. In the initial state, the distances at the ends of the first tooth 221 and the second tooth 222 extending out of the roller 21 are equal. When the adjusting rod 223 moves forward, the adjusting rod 223 pushes the second tooth 222 forward. At this time, since the tail of the first tooth 221 is tilted in the opposite direction to the tail of the second tooth 32, the first tooth 221 can move inward into the roller 21, so that the end of the first tooth 221 coincides with the outer wall of the roller 21.
[0041] The pushing assembly 224 also includes an electric cylinder 2241, which is fixedly connected to the base 1. A connecting frame 2242 is fixedly connected to the end of the pushing rod inside the electric cylinder 2241. Round rods 2243 are fixedly connected to both ends of the connecting frame 2242. The round rods 2243 are rotatably connected to the adjusting rod 223. By moving the connecting frame 2242 through the electric cylinder 2241, the round rods 2243 on the connecting frame 2242 can drive the adjusting rod 223 to move forward or backward. At the same time, since the round rods 2243 are rotatably connected to the adjusting rod 223, the round rods 2243 will not affect the adjusting rod 223 from rotating with the roller 21.
[0042] Movable teeth 221 and 222 are fixedly connected to fixed ears 41 on their upper and lower sides respectively. A groove 42 is provided inside the roller 21 at the fixed position. A limit rod 43 is fixedly connected to the roller 21 in the groove 42. The fixed ears 41 are slidably connected to the limit rod 43. A spring 44 is sleeved on the limit rod 43. One end of the spring 44 is fixedly connected to the fixed ear 41, and the other end of the spring 44 is fixedly connected to the roller 21. When movable teeth 221 are not pressed against by the adjusting rod 223, the force generated by the spring 44 causes movable teeth 221 to retract inward. At the same time, when the adjusting rod 223 moves backward, movable teeth 222 retract inward under the force of the spring 44, thereby achieving the purpose of resetting.
[0043] A limiting frame 51 is provided on the base 1. The upper end of the limiting frame 51 is an open end 52. The inner wall of the limiting frame 51 abuts against the wire nose cap 11. By providing the limiting frame 51 on the base 1, when in use, the wire nose cap 11 only needs to be inserted from the open end 52. Because the limiting frame 51 limits the wire nose cap 11, it will not flip or shift back and forth, thus making the indentation on its surface neat and uniform.
[0044] The lower end of the limiting frame 51 has an outlet end 53, which is used to pull out the wire nose cap 11. After one side is connected, the wire nose cap 11 can be pulled out from the bottom, and finally lifted upwards to complete the connection.
