[0002] Copper tube crimping of cables is a common cable connection method. It uses special tools to sleeve a copper tube on the cable and fixes the copper tube on the cable through pressure to establish a reliable electrical connection and mechanical connection, connecting two cables together.

[0003] When performing copper tube crimping, first, select copper tubes and cables of appropriate specifications to ensure that the size of the copper tube fits the diameter of the cable, and the cable should remove the external insulation layer to expose the internal wires. Then sleeve the prepared copper tube on the exposed wires of the cable, and then use special crimping tools, such as wire crimping pliers or crimping tools, to crimp the copper tube and the cable. So that the exposed copper wires of the two cables are both wrapped in the copper tube and the copper wires are in contact with each other.

[0004] Some high-voltage cables have a large diameter. Even after peeling off the armored part, the copper wires inside are very thick, and most of the copper wires stripped from the cable are loose, which is not very convenient when inserting the copper tube. If the copper wires are directly stuffed into the copper tube, some copper wires may be inserted backwards or cannot be inserted, thus affecting the performance of the cable docking copper wires for power conduction. However, if the copper wires are manually twisted and inserted, since the copper wires are relatively thick and not easy to twist, and vigorously twisting may hurt the hand. When performing a large number of docking operations, it is time-consuming and laborious, the operation is troublesome, and the docking efficiency is reduced.

[0019] An annular slide groove is opened on the side wall of the middle fixed ring. Two groove depth slide holes are arranged on the annular slide groove.

A convex ring is arranged on one side of the middle of the transmission column adjacent to the first through plate. One end of the adaptive spring abuts against the second through plate, and the other end of the adaptive spring abuts against the convex ring.

[0024] The present invention has the following beneficial effects:

[0025] 1. For the butt joint device used in cable production, the cable armor end can be fixed through the setting of the cable clamping mechanism, and the cable copper wire end can be clamped through the setting of the copper wire clamping mechanism. Through the threaded fit of the outer fixed cylinder and the inner movable cylinder, when the inner movable cylinder is stressed, it can move and rotate inside the outer fixed cylinder. This movement conforms to the operation of twisting the cable copper wire. Therefore, in this solution, a straight groove inclined plate is arranged on the inner side of the inner movable cylinder, and the copper wire clamping mechanism is slidably engaged with the straight groove inclined plate. The driving seat is used to pull the copper wire clamping mechanism to translate. When the copper wire clamping mechanism moves to the end of the chute of the straight groove inclined plate, the copper wire clamping mechanism cannot slide relative to the straight groove inclined plate. At this time, when the copper wire clamping mechanism continues to move, it will drive the straight groove inclined plate to move together. Because the straight groove inclined plate is connected to the inner movable cylinder, the inner movable cylinder drives the straight groove inclined plate and the copper wire clamping mechanism to move and rotate inside the outer fixed cylinder while moving.

[0026] Through the cooperation of the straight groove inclined plate and the copper wire clamping mechanism, when the copper wire clamping mechanism moves along the straight groove inclined plate, the copper wire clamping mechanism gradually clamps the cable copper wire end. Therefore, when the inner movable cylinder rotates, the copper wire clamping mechanism twists the cable copper wire until the copper wire clamping mechanism disengages from the copper wire end.

[0027] In this solution, the operator only needs to operate the driving part, and the copper wire clamping mechanism can automatically clamp the cable copper wire, and then drive the copper wire to rotate and twist, so that the cable copper wire meets the standard of copper tube crimping, which is convenient for cable butt joint. The manual operation is simple, the labor cost is reduced, the copper tube crimping is more convenient, and the butt joint power-on effect and overall efficiency are improved.

[0028] 2. For the butt joint device used in cable production, through the cooperation of the active clamping ring, the passive clamping ring and the rope, when the lifting part drives the active clamping ring to move down, since the length of the rope is fixed, the rope between the first butt joint plate and the pulley becomes longer, and the rope between the second butt joint plate and the pulley will become shorter, so that the passive clamping ring moves up synchronously, and the upward movement degree is the same as the downward movement degree of the active clamping ring, thus realizing the simultaneous clamping of the cable by the active clamping ring and the passive clamping ring, preventing the cable armor end from rotating with the copper wire end, and improving the reliability of this butt joint device.

[0029] 3. For the butt joint device used in cable production, through the setting of the adaptive component, when the active clamping ring and the passive clamping ring clamp the cable armor end, the copper wire clamping mechanism will synchronously clamp the cable copper wire end and the clamping degree is almost in the same proportion;

[0030] Since the conduction rack is connected to the active clamping ring and the passive clamping ring, when the active clamping ring and the passive clamping ring move, the conduction rack will move, and the conduction rack meshes with the transmission gear to make it rotate;

[0031] Through the settings of the middle fixing ring, annular sliding groove and groove-depth sliding hole, when the transmission column contacts the middle fixing ring, different degrees of insertion will occur. Therefore, the double-sided rack connected to the transmission column will move back and forth, realizing meshing with the transmission gear or docking with the single-sided rack;

[0032] At the beginning of the operation, the transmission column is inserted into the groove-depth sliding hole. Therefore, at the beginning, the double-sided rack meshes with the transmission gear. At this time, the cable clamping mechanism clamps and drives the two transmission gears to rotate, causing the double-sided rack to move down proportionally to clamp the copper wire end. When the inner movable cylinder starts to rotate, the transmission column first rotates along the annular sliding groove and then quickly separates from the middle fixing ring. During this process, the double-sided rack separates from the transmission gear and then immediately docks and engages with the single-sided rack, keeping the height of the straight groove inclined plate unchanged;

[0033] In this solution, cables with the same armor thickness but different copper wire diameters can be twisted and docked. Through the transmission of the adaptive component by the cable clamping mechanism, the copper wire clamping mechanism automatically adjusts the clamping degree without additional adjustment, greatly improving the scope and flexibility of the use of this device.

Detailed implementation manner

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] Embodiment 1. The purpose of this embodiment is to facilitate the solution of the problem that most of the copper wires stripped from the cable are loose, which is not convenient when inserting them into the copper tube. If the copper wires are directly stuffed into the copper tube, some copper wires will be inserted backwards or cannot be inserted, thus affecting the performance of the cable to connect the copper wires to conduct electricity. However, if the copper wires are manually twisted and inserted, it will be time-consuming and laborious during a large number of docking operations, the operation is troublesome, and the docking efficiency is reduced. Please refer to Figures 1 - 10 , a docking device for cable production, including a substrate 110. Above the substrate 110, a top plate 120 is installed through a support side plate 130. Between the substrate 110 and the top plate 120, there is a cable clamping mechanism 300 for clamping and fixing the armored end of the cable. At the bottom side of the top plate 120, an outer fixed cylinder 210 is installed. Inside the outer fixed cylinder 210, an inner movable cylinder 220 is installed in a threaded manner. In the middle of the inner movable cylinder 220, there is a copper wire clamping mechanism 400 for twisting the copper wire end of the cable instead of manual labor. Inside the inner movable cylinder 220, a straight groove inclined plate 710 for automatically adjusting the clamping degree of the copper wire clamping mechanism 400 is movably arranged. See Figure 5 and Figure 6, the straight-grooved inclined plate 710 is set as an inclined plate with a straight card slot on the bottom side, and the straight-grooved inclined plate 710 inclines downward towards the cable copper wire end.

[0047] See Figure 1 and Figure 2 , a driving seat 240 is slidably installed on the side of the substrate 110, a driving member 250 for driving the driving seat 240 to slide is installed on the driving seat 240, and the driving seat 240 is connected to the copper wire clamping mechanism 400. The driving member 250 in this solution can also be set as a reciprocating member driven by a servo motor or other suitable devices.

[0048] Specifically, when the driving member 250 drives the driving seat 240 to move, the copper wire clamping mechanism 400 moves and rotates.

[0049] See Figure 3 and Figure 4 , the copper wire clamping mechanism 400 includes two arc-shaped rotating clamping rings 410. Elastic folding rubber sheets 420 are connected to both ends of the rotating clamping ring 410. Pressure arms 430 are connected to both the upper and lower sides of the rotating clamping ring 410. The ends of the pressure arms 430 are slidably engaged with the straight-grooved inclined plate 710. When the pressure arms 430 move along the straight-grooved inclined plate 710, the distance between the two rotating clamping rings 410 is adjusted.

[0050] The elastic folding rubber sheet 420 is set as a corrugated rubber sleeve with a spring inside. Through the setting of the elastic folding rubber sheet 420, the ends of the two rotating clamping rings 410 are seamlessly connected. The elastic folding rubber sheet 420 can be unfolded or folded as the distance between the rotating clamping rings 410 changes. When the copper wire clamping mechanism 400 clamps the cable copper wire, all copper wires are wrapped to prevent copper wires from leaking out and not participating in stranding, affecting cable docking, and improving the quality of cable docking.

[0051] An integrated driving ring 230 is provided at the upper end of the driving seat 240. The driving ring 230 is coaxially arranged with the outer fixed cylinder 210. Two traction arms 260 are vertically installed on the side wall of the driving ring 230. An adapter collar 270 is connected to the end of the traction arm 260. The adapter collar 270 is sleeved outside the pressure arm 430. The driving member 250 is set as a pull rod installed on the driving seat 240 by bolts. A guiding chute 140 is opened at the front end of the substrate 110. The bottom of the driving seat 240 is slidably matched with the guiding chute 140.

[0052] The cable armor end can be fixed by the setting of the cable clamping mechanism 300. The cable copper wire end can be clamped by the setting of the copper wire clamping mechanism 400. Through the threaded fit of the outer fixed cylinder 210 and the inner movable cylinder 220, the inner movable cylinder 220 can move and rotate inside the outer fixed cylinder 210 under force. This movement conforms to the operation of twisting the cable copper wire. Therefore, a straight groove inclined plate 710 is arranged inside the inner movable cylinder 220, and the copper wire clamping mechanism 400 is slidably engaged with the straight groove inclined plate 710, and the driving seat 240 is used to pull the copper wire clamping mechanism 400 to translate.

[0053] See Figure 7 , when the copper wire clamping mechanism 400 moves to the end of the chute of the straight groove inclined plate 710, the copper wire clamping mechanism 400 cannot slide relative to the straight groove inclined plate 710. At this time, if the copper wire clamping mechanism 400 continues to move, it will drive the straight groove inclined plate 710 to move together. Because the straight groove inclined plate 710 is connected to the inner movable cylinder 220, power is provided for the inner movable cylinder 220, so that the inner movable cylinder 220 drives the straight groove inclined plate 710 and the copper wire clamping mechanism 400 to move and rotate inside the outer fixed cylinder 210.

[0054] In this embodiment: through the cooperation of the straight groove inclined plate 710 and the copper wire clamping mechanism 400, when the copper wire clamping mechanism 400 moves along the straight groove inclined plate 710, the copper wire clamping mechanism 400 gradually clamps the cable copper wire end. Therefore, when the inner movable cylinder 220 rotates, the copper wire clamping mechanism 400 twists the cable copper wire until the copper wire clamping mechanism 400 disengages from the copper wire end; in this solution, the operator only needs to operate the driving member 250, and the copper wire clamping mechanism 400 can automatically clamp the cable copper wire, and then drive the copper wire to rotate and twist, so that the cable copper wire meets the standard of copper tube crimping, which is convenient for cable docking, the manual operation is simple, the labor cost is reduced, the copper tube crimping is more convenient, and the docking power-on effect and overall efficiency are improved.

[0055] Embodiment 2. The purpose of this embodiment is to facilitate the solution of the problem that the cable armor end needs to be clamped, otherwise the entire front end of the cable will rotate when the copper wire end rotates. This embodiment is an improvement based on Embodiment 1. Specifically, please refer to Figures 1 - 10 , the cable clamping mechanism 300 includes an active clamping ring 310 and a passive clamping ring 320. Both the active clamping ring 310 and the passive clamping ring 320 are set as arc-shaped jigs. A lifting member 350 is installed on the bottom side of the top plate 120. In this solution, the lifting member 350 can be set as an electric telescopic rod or a cylinder. The lifting member 350 is a common tool and will not be elaborated here.

[0056] The telescopic end of the lifting member 350 is connected to the top of the active clamping ring 310. The passive clamping ring 320 is located below the active clamping ring 310. A telescopic rod 360 for limiting and guiding the passive clamping ring 320 is installed on the substrate 110. The telescopic rod 360 is set as a common plug-in sleeve rod, mainly for limiting and guiding. The active clamping ring 310 is in transmission connection with the passive clamping ring 320. When the active clamping ring 310 moves downward, the passive clamping ring 320 moves upward synchronously.

[0057] A pulley 370 is rotatably installed on the bottom side of the top plate 120. Two ends of the active clamping ring 310 are connected with horizontally transverse first docking plates 311. Second docking plates 321 are correspondingly arranged at two ends of the passive clamping ring 320. A return spring 340 is connected between the second docking plate 321 and the first docking plate 311. The return spring 340 is set as a compression spring. A through hole 330 is formed in the first docking plate 311. A rope 380 is fixedly installed on the first docking plate 311. The rope 380 is set as a non-elastic steel cable rope. The other end of the rope 380 passes through the pulley 370 and the through hole 330 in sequence, and the other end of the rope 380 is fixedly connected with the second docking plate 321.

[0058] In this embodiment: Through the cooperation of the active clamping ring 310, the passive clamping ring 320 and the rope 380, when the lifting member 350 drives the active clamping ring 310 to move downward, since the length of the rope 380 is fixed, the rope 380 between the first docking plate 311 and the pulley 370 becomes longer, and the rope 380 between the second docking plate 321 and the pulley 370 will become shorter, so that the passive clamping ring 320 moves upward synchronously, and the upward movement degree is the same as the downward movement degree of the active clamping ring 310, thereby realizing the simultaneous clamping of the cable by the active clamping ring 310 and the passive clamping ring 320, preventing the cable armor end from rotating along with the copper wire end, and improving the reliability of this docking device.

[0059] Embodiment Three. The purpose of this embodiment is to promote the solution of the problem of properly clamping cables with different copper wire diameters automatically. This embodiment is an improvement made on the basis of Embodiment Two. Specifically, please refer to Figures 1 - 10 , a middle fixing ring 610 is fixedly installed on the bottom side of the top plate 120. An adaptive component 500 is arranged between the middle fixing ring 610, the cable clamping mechanism 300 and the straight groove inclined plate 710. When the clamping degree of the cable clamping mechanism 300 changes, the copper wire clamping mechanism 400 adjusts the clamping degree proportionally.

[0060] The adaptive component 500 includes a conduction rack 510 fixedly connected to the clamping end of the cable clamping mechanism 300, a transmission gear 520 rotatably installed in the middle of the middle fixing ring 610, a unilateral rack 540 fixedly installed on the inner side of the inner movable cylinder 220, and a double-sided rack 530 moving between the transmission gear 520 and the unilateral rack 540.

[0061] See Figure 3 There are two conduction racks 510 symmetrically arranged. The two conduction racks 510 are respectively racks connected to the active clamping ring 310 and the passive clamping ring 320.

[0062] The conduction rack 510 remains meshed with the transmission gear 520. The transmission gear 520 is set as two mutually meshing gears. One of them remains meshed with the conduction rack 510, and the other is intermittently meshed with the double-sided rack 530. When the double-sided rack 530 meshes with the transmission gear 520, the height of the straight groove inclined plate 710 is adjusted accordingly. When the double-sided rack 530 is butted and engaged with the single-sided rack 540, the height of the straight groove inclined plate 710 is locked.

[0063] A vertical limit slide bar 720 is connected between the straight groove inclined plate 710 and the inner movable cylinder 220. A rectangular slide groove 711 is transversely opened at one end of the straight groove inclined plate 710. Rectangular limit blocks 560 are installed on the smooth surfaces on both sides of the double-sided rack 530. The rectangular limit blocks 560 are slidably engaged with the rectangular slide groove 711.

[0064] A circular slide groove 620 is opened on the side wall of the middle fixed ring 610. There are two groove-depth slide holes 630 on the circular slide groove 620. The groove depth of the two groove-depth slide holes 630 is greater than the groove depth of the circular slide groove 620. The groove-depth slide holes 630 and the circular slide groove 620 are connected by an inclined surface. The position where the groove-depth slide holes 630 are located corresponds to the position of the transmission gear 520. Since the conduction rack 510 is connected to the active clamping ring 310 and the passive clamping ring 320, when the active clamping ring 310 and the passive clamping ring 320 move, the conduction rack 510 will move, and the conduction rack 510 meshes with the transmission gear 520 to make it rotate. Through the settings of the middle fixed ring 610, the circular slide groove 620 and the groove-depth slide holes 630, when the transmission column 550 contacts the middle fixed ring 610, different degrees of insertion will occur. Therefore, the double-sided rack 530 connected to the transmission column 550 will move back and forth, realizing meshing with the transmission gear 520 or butting with the single-sided rack 540.

[0065] A first through plate 570 is slidably engaged on the side of the double-sided rack 530. The first through plate 570 is longitudinally slidably matched with the double-sided rack 530. A second through plate 580 is installed on the back side of the single-sided rack 540. The second through plate 580 and the first through plate 570 are jointly inserted with a transmission column 550. The second through plate 580 is set as a mounting plate with a rectangular hole. The transmission column 550 is set as a column with a rectangular tail end. The tail end of the transmission column 550 is inserted and slidably matched with the second through plate 580, so that the double-sided rack 530 can move up, down, back and forth without rotation.

[0066] See Figure 8 When the double-sided rack 530 meshes with the transmission gear 520, the transmission column 550 extends into the groove-depth slide hole 630.

[0067] SeeFigure 9 When the double-sided rack 530 is butted with the single-sided rack 540, the transmission column 550 is far away from the groove-depth sliding hole 630.

[0068] See Figure 5 An adaptive spring 590 is sleeved outside the transmission column 550. The adaptive spring 590 is located between the first through plate 570 and the second through plate 580. A convex ring is arranged on one side of the middle part of the transmission column 550 adjacent to the first through plate 570. One end of the adaptive spring 590 abuts against the second through plate 580, and the other end of the adaptive spring 590 abuts against the convex ring, so that the transmission column 550 is kept pressed towards the middle fixing ring 610.

[0069] In this embodiment: Through the setting of the adaptive component 500, when the active clamping ring 310 and the passive clamping ring 320 clamp the armored end of the cable, the copper wire clamping mechanism 400 will synchronously clamp the copper wire end of the cable and the clamping degree is basically in the same proportion.

[0070] At the beginning of the operation, the transmission column 550 is inserted into the groove-depth sliding hole 630. Therefore, at the beginning, the double-sided rack 530 meshes with the transmission gear 520. At this time, the cable clamping mechanism 300 clamps and drives the two transmission gears 520 to rotate, so that the double-sided rack 530 moves down synchronously to clamp the copper wire end. When the inner movable cylinder 220 starts to rotate, the transmission column 550 first rotates along the annular sliding groove 620 and then quickly separates from the middle fixing ring 610. During this process, the double-sided rack 530 separates from the transmission gear 520 and then immediately butts and engages with the single-sided rack 540, so that the height of the straight groove inclined plate 710 remains unchanged.

[0071] In this solution, cables with the same armored thickness but different copper wire diameters can be twisted and butted. Through the transmission of the adaptive component 500 by the cable clamping mechanism 300, the copper wire clamping mechanism 400 automatically adjusts the clamping degree without additional adjustment, which greatly improves the application range and flexibility of the device.

[0073] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
