A screwing component 4 is installed on the clamping component 3.

[0031] The present invention is used to combine and crimp two electric wires together, and before the electric wires are inserted into the crimping terminal, the present invention can first twist the exposed multiple strands of the electric wire into one strand, thereby increasing the efficiency of combining and crimping the two electric wires; specifically, firstly, the crimping terminal is placed in the crimping component 2, and then the exposed end of the conductor of the electric wire is placed in the twisting component 4, and the twisting component 4 is controlled to clamp the exposed conductor of the electric wire, and then the electric wire is straightened and the other end of the electric wire is placed in the clamping component 3, and the clamping component 3 is controlled to clamp and fix the electric wire, and then according to the insertion depth of the electric wire, the two clamping components 3 are controlled to drive the two electric wires to move in a direction close to each other, so that the two clamping components 3 drive the twisting component 4 to completely insert the exposed conductor part of the electric wire into the crimping terminal.

[0032] Since the two clamping parts 3 are arranged in an alternating manner front to back, the conductor parts of the two wires are inserted into the two ends of the crimping terminal in an alternating manner front to back, and before the twisting part 4 inserts the exposed conductor part of the wire into the crimping terminal, the twisting part 4 can twist the exposed multiple strands of the wire into one strand, and finally the pressing part 2 is controlled to crimp and merge the two wires, and the twisting part 4 and the clamping part 3 are controlled to loosen the wires, and the two crimped and merged wires are taken out of the pressing part 2, thereby realizing the crimping and merging of the two wires.

[0033] See also Figure 1 and Figure 2 Guide grooves are provided on both sides of the upper end of the base 1, and the two guide grooves are arranged alternately front to back. The clamping component 3 includes a sliding plate 31 slidably installed in the guide groove left to right, and an electric push rod 32 is connected between the sliding plate 31 and the guide groove. A synchronization component 33 is installed on the upper end of the sliding plate 31, and two clamping plates 34 symmetrically arranged front to back are installed on the synchronization component 33. The synchronization component 33 is used to drive the two clamping plates 34 to move synchronously.

[0034] The clamping component 3 is used to clamp the wire; specifically, after the exposed conductor of the wire is clamped by the screwing component 4, the wire is straightened and the other end of the wire is placed in the two clamping plates 34, and then the synchronization component 33 is controlled to drive the two clamping plates 34 to move in a direction close to each other, so that the two clamping plates 34 clamp the wire, and then the electric push rod 32 is controlled to drive the two sliding plates 31 to move in a direction close to each other, so that the two sliding plates 31 drive the wires clamped by the clamping plates 34 to move in a direction close to each other through the synchronization component 33, so that the screwing component 4 completely inserts the exposed conductor part of the wire into the crimping terminal, and when the two wires are crimped and combined, the synchronization component 33 is controlled to drive the two clamping plates 34 to move in a direction away from each other and release the wires, so as to take out the two wires after crimping and combining, and the electric push rod 32 is controlled to drive the sliding plate 31 to return to its initial position.

[0035] See also Figure 2and Figure 3 The synchronization assembly 33 includes two synchronization plates 331 symmetrically arranged front and back and mounted on the upper end of the sliding plate 31 for sliding back and forth. A double-headed screw 332 is rotatably mounted on the sliding plate 31, and the two threaded segments at the two ends rotate in opposite directions. The two synchronization plates 331 are respectively threadedly connected to the corresponding threaded segments, and the opposite sides of the two synchronization plates 331 are connected to their corresponding clamping plates 34 through two left-right symmetrically arranged top spring rods 333.

[0036] The synchronization component 33 is used to drive the two clamping plates 34 to move towards each other; specifically, when the clamping plates 34 are needed to clamp the wires, the two synchronization plates 331 are driven to move towards each other through threaded cooperation by manually screwing the double-headed screw 332, so that the two synchronization plates 331 drive the two clamping plates 34 to move towards each other through the top extension spring rod 333, so that the clamping plates 34 clamp the wires in an elastic manner under the action of the top extension spring rod 333. After the two wires are combined and crimped, the clamping plates 34 are manually pushed in the direction away from each other, so that the wires can be quickly taken out of the two clamping plates 34, thereby further increasing the efficiency of the combined crimping of the wires.

[0037] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 The screwing component 4 includes two transmission rods 41 of elastic telescopic structure symmetrically arranged front and back fixedly mounted on opposite sides of the two sliding plates 31, a U-shaped plate 42 is fixedly mounted on one end of the two transmission rods 41 away from the sliding plate 31, a rotating cylinder 43 is rotatably mounted on the middle part of the U-shaped plate 42 away from the sliding plate 31, and two screwing plates 44 of arc-shaped structure symmetrically arranged up and down are distributed in the rotating cylinder 43, the front and rear ends of the two screwing plates 44 are arranged with matching tooth structures, and a fitting component 45 for driving the screwing plates 44 to clamp the wires is installed between the two screwing plates 44 and the rotating cylinder 43; the end of the rotating cylinder 43 close to the sliding plate 31 rotates through the U-shaped plate 42 and is installed with a rotating component 46 for driving the rotating cylinder 43 to rotate, and the end of the rotating cylinder 43 away from the sliding plate 31 is installed with a straightening component 47 for straightening the wires; wherein, the opposite sides of the two screwing plates 44 are set to be softer rubber material.

[0038] See also Figure 2 and Figure 3 Two front-to-rear symmetrically arranged fixing plates 311 are fixedly mounted on the upper end of the sliding plate 31, and an adjusting screw 312 is installed on the fixing plate 311 by threaded engagement. A positioning plate 313 is fixedly mounted on one side of the adjusting screw 312 close to the middle of the base 1.

[0039] The screwing component 4 is used to clamp the exposed conductor part of the wire and twist the multiple conductors of the wire into one strand; specifically, first place one end of the exposed conductor of the wire on the opposite side of the two screwing plates 44, and control the fitting component 45 to drive the two screwing plates 44 to fit on the outside of the wire and enable the screwing plates 44 to clamp the wire, the opposite sides of the two screwing plates 44 are set to rubber material, so as to protect the conductor part of the wire, and the front and rear ends of the two screwing plates 44 are set to matching tooth structures, so that the two screwing plates 44 can stably clamp the end of the wire, and then according to the insertion depth of the wire, the positioning plate 313 is driven to move a distance towards the U-shaped plate 42 by manually screwing the adjustment screw 312.

[0040] When the two sliding plates 31 move toward each other, the two sliding plates 31 drive the two U-shaped plates 42 to move toward each other through the transmission rod 41, so that the U-shaped plate 42 drives the wires clamped by the two screwing plates 44 to move toward the direction close to the pressing component 2 through the rotating cylinder 43 and the fitting assembly 45, and when the rotating cylinder 43 moves to the corresponding position of the pressing component 2, the pressing component 2 can block the rotating cylinder 43 and compress the transmission rod 41 through the U-shaped plate 42, and the two clamping plates 34 can continue to drive the wires to move toward the direction close to the pressing component 2 , so that the two twisting plates 44 move relative to the wire in the direction away from the pressing component 2, and under the action of the rotating component 46, the two twisting plates 44 can rotate while moving relative to the wire in the direction away from the pressing component 2, so that the twisting plates 44 can twist the exposed multiple wires of the wire into one strand, and when the twisting plates 44 move to the corresponding position of the insulation layer of the wire, since the opposite sides of the two twisting plates 44 are set to a softer rubber material, the insulation layer of the wire can compress the rubber material of the twisting plates 44, so that the two twisting plates 44 will not squeeze and bend the wire.

[0041] When the rotating cylinder 43 drives the U-shaped plate 42 to move closer to the sliding plate 31 relative to the sliding plate 31 under the action of the pressing component 2, the end of the exposed conductor of the wire can be gradually moved out of the rotating cylinder 43 and inserted into the crimping terminal. When the U-shaped plate 42 moves to the corresponding position of the positioning plate 313, the electric push rod 32 is controlled to stop driving the sliding plate 31 to move. The insertion depth of the wire is controlled by controlling the position of the positioning plate 313. At the same time, the straightening component 47 can straighten one end of the wire inserted into the crimping terminal, thereby ensuring that the exposed conductor part of the wire can be fully inserted into the crimping terminal, thereby ensuring the electrical connection quality of the two wires after combined crimping.

[0042] See also Figure 2-Figure 4The rotating assembly 46 includes a driven bevel gear 461 fixedly sleeved on the outside of the rotating cylinder 43 and located in the U-shaped plate 42. The front part of the driven bevel gear 461 away from the middle part of the base 1 is meshed with a transmission bevel gear 462.

The positions of the two sliding plates 31 corresponding to the driving gear 464 are fixedly installed with racks 314, and the racks 314 and the driving gear 464 are meshed.

[0043] The rotating assembly 46 is used to drive the rotating cylinder 43 to rotate; specifically, when the rotating cylinder 43 drives the U-shaped plate 42 to move closer to the sliding plate 31 relative to the sliding plate 31 under the action of the pressing component 2, the active gear 464 drives the transmission bevel gear 462 to rotate through the rotating shaft 463 under the action of the rack 314, so that the transmission bevel gear 462 drives the driven bevel gear 461 to rotate, and then the driven bevel gear 461 drives the rotating cylinder 43 to rotate, so that the rotating cylinder 43 drives the screwing plate 44 to rotate through the fitting assembly 45, so that the two screwing plates 44 can move relative to the wire in the direction away from the pressing component 2 and can rotate at the same time, so that the screwing plate 44 can twist the exposed multiple wires of the wire into one strand.

[0044] See also Figure 1 and Figure 8 The pressing component 2 includes a fixed seat 21 fixedly installed in the middle of the upper end of the base 1, a lower pressing die 22 is fixedly installed in the middle of the upper side of the fixed seat 21, a U-shaped connecting plate 23 is also fixedly installed on the upper side of the fixed seat 21, a hydraulic rod 24 is fixedly installed on the lower inner wall of the connecting plate 23, an upper pressing die 26 is fixedly installed at the lower end of the hydraulic rod 24 through a transmission block 25, and an L-shaped unlocking rod 27 is fixedly installed on both sides of the transmission block 25.

[0045] The crimping component 2 is used to crimp the wires together; specifically, first place the crimping terminal on the lower die 22, and when the rotating cylinder 43 moves to the corresponding position of the fixed seat 21, the fixed seat 21 can block the rotating cylinder 43, so that the exposed conductor part of the wire can be inserted into the crimping terminal, and then control the hydraulic rod 24 to drive the upper die 26 to move downward through the transmission block 25, so that the upper die 26 and the lower die 22 cooperate to crimp the two wires and the crimping terminal together, and finally control the hydraulic rod 24 to drive the upper die 26 to return to the initial position through the transmission block 25, and take out the two wires that have been crimped and merged, thereby completing the crimping and merging of the two wires.

[0049] The fitting component 45 is used to drive the two screwing plates 44 to fit together on the outside of the wire; specifically, first, the synchronous sleeve 432 is moved in a direction away from the matching ring 452, so that the synchronous sleeve 432 drives the locking rod 433 to move out of the locking hole and compress the reset spring 431, and then the matching ring 452 is manually rotated, so that the matching ring 452 drives the adjusting ring 453 to rotate and compress the arc spring 457 through the connecting block 451, and the adjusting ring 453 drives the two sliding rods 455 to move towards each other under the action of the fixing ring 454 through the inclined groove and the matching rod 456, so that the two sliding rods 455 drive the two screwing plates 44 to fit together on the outside of the wire, and the synchronous sleeve 432 drives the locking rod 433 to be inserted into the corresponding locking hole under the action of the reset spring 431, so as to lock the matching ring 452, so that the two screwing plates 44 are always fitted to the outside of the wire.

[0050] When the hydraulic rod 24 drives the transmission block 25 to move downward, the transmission block 25 drives the unlocking rod 27 to move downward, and the inclined surface of the vertical section of the unlocking rod 27 drives the synchronous sleeve 432 to move away from the matching ring 452, so that the locking rod 433 moves out of the locking hole again, so that the connecting block 451 drives the adjusting ring 453 to return to the initial position under the action of the arc spring 457, and then the two sliding rods 455 drive the two screwing plates 44 to return to the initial position, so that the two screwing plates 44 are no longer attached to the outside of the wires, and then when the two wires are combined and crimped, the combined and crimped wires can be quickly taken out, further increasing the efficiency of the combined crimping of the wires.

[0053] The straightening assembly 47 is used to straighten one end of the stripped wire; specifically, when the hydraulic rod 24 drives the transmission block 25 to move downward, the transmission block 25 drives the L-shaped plate 28 to move downward through the unlocking rod 27, and when the L-shaped plate 28 moves to the corresponding position of the matching sleeve 434, the L-shaped plate 28 and the matching sleeve 434 inclined surface cooperate to drive the matching sleeve 434 to move in a direction away from the middle of the base 1, so that the matching sleeve 434 drives the lower pressure ring 435 to move in the direction of the middle of the base 1, and the lower pressure ring 435 and the inclined surface of the square spring rod 473 cooperate to drive the two square spring rods 473 to move in the direction, so that the square spring rod 473 drives the two arc plates 471 to move in a direction close to each other through the inclined rod 472. When the two arc plates 471 are attached to the outside of the wire, the wire can block the arc plate 471, and then when the two square spring rods 473 continue to move in the direction of approaching each other, the two arc plates 471 can straighten the wire toward the middle of the base 1 under the action of the inclined rod 472, so that the exposed wire can be fully inserted into the crimping terminal, further ensuring the electrical connection quality after the two wires are combined and crimped. When the transmission block 25 returns to its initial position, the square spring rod 473 drives the arc plate 471 to return to its initial position through the inclined rod 472, and at the same time, the inclined surface of the square spring rod 473 and the lower pressure ring 435 cooperate to drive the matching sleeve 434 to return to its initial position.

[0054] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
