[0002] The production process of cable joints generally includes cutting long cables, stripping the cable ends to expose the wire cores, and sleeved and crimped the wire cores with wire noses. In a few cases, the cables need to be straightened first and then bent into the required shape.

[0003] During production, use cable cutters or cutting tools to cut long cables to the required length, and then use stripping tools such as wire strippers to strip the outer sheath of the cable end to expose the internal conductor core. The stripping length should match the crimping part of the wire nose to avoid damaging the conductor. Insert the stripped conductor core into the cylindrical barrel of the wire nose, and use crimping pliers to tighten the wire nose to ensure that the crimping is firm. After the cable joint is completed, it needs to be inspected to ensure that the subsequent electrical connection is reliable.

[0004] In the prior art, workers need to use multiple tools in sequence to make cable connectors, which is not easy to operate, has a long production process, and the tools are relatively scattered and lack integration. Summary of the invention

DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] See also Figure 1-Figure 10 The cable joint manufacturing equipment for power construction provided by the embodiment of the present invention mainly includes a seat body 1.1, a driving motor 6, an electric telescopic rod 9, a rotating part 7, a shearing assembly 10, a clamp assembly 11, a first clamping member 13 and a second clamping member 14.

[0022] A cover plate 1.2 is detachably connected to the top of the base body 1.1, and a groove 1.4 is provided on the cover plate 1.2 for evading the rotating part 7 and the electric telescopic rod 9. A heat dissipation window 1.3 is provided on one side of the base body 1.1, and the heat dissipation window 1.3 is located near the drive motor 6. A control panel 1.5 for controlling the drive motor 6 and the electric telescopic rod 9 is also provided on the base body 1.1.

[0023] The seat body 1.1 is fixedly connected with a mounting frame 2, a slide rail 3 is fixedly connected to the mounting frame 2, and a screw rod 5 is rotatably connected to the mounting frame 2, and the screw rod 5 is arranged parallel to the slide rail 3. The slide seat 4 is slidably connected to the slide rail 3 through a linear bearing, and the slide seat 4 has a proximal position close to the second clamping member 14 and a distal position away from the second clamping member 14 in the sliding stroke on the slide rail 3. The proximal position and the distal position are respectively the limit positions at both ends of the sliding stroke of the slide seat 4 on the slide rail 3. The slide seat 4 is also embedded with a threaded sleeve, and the threaded sleeve is threadedly connected to the screw rod 5. The output shaft of the drive motor 6 is connected to the screw rod 5 through a gear 12.1 group, so that the drive motor 6 can drive the screw rod 5 to rotate, and the screw rod 5 drives the slide seat 4 to move along the slide rail 3 by threading with the threaded sleeve. The drive motor 6 adopts a reduction motor, or a servo motor and a reducer combination component, and the power output by the servo motor is transmitted to the screw rod 5 through the reducer.

[0024] The rotating part 7 is composed of a shaft 7.1, a connecting rod 7.2 and a guide seat 7.3. The connecting rod 7.2 connects the shaft 7.1 and the guide seat 7.3. The shaft 7.1 is rotatably connected to the slide seat 4 through a bearing. The rotating part 7 as a whole can rotate on the slide seat 4. Figure 7 Two limit grooves 15 are provided on the circumferential side of the shaft rod 7.1. The two limit grooves 15 are distributed 180 degrees along the circumference of the shaft rod 7.1. An annular groove 16 is also provided on the circumferential side of the shaft rod 7.1. The annular groove 16 passes through the two limit grooves 15. The depth of the annular groove 16 is shallower than the two limit grooves 15. The intersection of the annular groove 16 and the two limit grooves 15 is chamfered, and the annular groove 16 smoothly transitions into the limit groove 15. Figure 6 The slide 4 is also fixedly mounted with an elastic telescopic rod 17, the elastic telescopic end of the elastic telescopic rod 17 abuts against the annular groove 16, and as the shaft 7.1 rotates, the elastic telescopic end can be inserted into the limiting groove 15, thereby preventing the rotating part 7 from rotating without applying an active rotation force to the rotating part 7. Moreover, the advantage of the chamfering treatment is that when the elastic telescopic end is located near the limiting groove 15, it can be chamfered and guided into the limiting groove 15.

[0025] The shearing assembly 10 comprises two blades 10.2, which are respectively mounted on two tool holders 10.1. The two tool holders 10.1 are respectively slidably connected in the slide grooves of the tool holders 10.1 on the guide seat 7.3. A first slider 10.3 is slidably connected to one side of the guide seat 7.3. Both ends of the first slider 10.3 are rotatably connected to first swing rods 10.4. One end of the two first swing rods 10.4 away from the first slider 10.3 is rotatably connected to the two tool holders 10.1. The two first swing rods 10.4 are arranged in an "eight" shape. The blades of the two blades 10.2 are both in a "V" shape. The first slider 10.3 and the two first swing rods 10.4 can make the two tool holders 10.1 slide relative to each other on the guide seat 7.3, that is, synchronously slide in the opposite direction to close or separate, so that the two blades 10.2 can be sheared in cooperation. The shearing assembly 10 is also provided with a first return spring 10.6, and the process of restoring the deformation of the first return spring 10.6 drives the two blades 10.2 to slide and separate synchronously in the opposite direction. For example, the first return spring 10.6 is a first torsion spring sleeved on any rotating shaft of the shearing assembly 10, and the two ends of the first torsion spring are connected one-to-one with the two components rotating through the rotating shaft; or the first return spring 10.6 adopts a first tension spring, one end of which is connected to the side of the guide seat 7.3 close to the blade 10.2, and the other end is connected to the first sliding block; or the first tension spring is connected between the two tool holders 10.1. The first contact plate 10.5 is welded on the lower tool holder 10.1.

[0026] The clamp assembly 11 includes two clamps 11.2, which are respectively mounted on two clamp frames 11.1. The two clamp frames 11.1 are respectively slidably connected in the clamp frame 11.1 grooves on the guide seat 7.3. The other side of the guide seat 7.3 is laterally slidably connected with a second slider 11.3, and the two ends of the second slider 11.3 are respectively rotatably connected with a second swing rod 11.4, and the ends of the two second swing rods 11.4 away from the second slider 11.3 are respectively rotatably connected to the two clamp frames 11.1. The clamp assembly 11 is also provided with a second return spring 11.6, and the process of restoring the deformation of the second return spring 11.6 drives the two clamps 11.2 to synchronously slide and separate in the opposite direction. For example, the second reset spring 11.6 is a second torsion spring sleeved on any rotating shaft of the crimping assembly, and the two ends of the second torsion spring are connected one-to-one with the two parts rotating through the rotating shaft; or the second reset spring 11.6 adopts a second tension spring, one end of which is connected to the side of the guide seat 7.3 close to the pressure clamp 11.2, and the other end is connected to the second sliding block; or the second tension spring is connected between the two clamp frames 11.1. The second contact plate 11.5 is welded on the lower clamp frame 11.1. The structure of the pressure clamp assembly 11 is similar to that of the shearing assembly 10, and the main difference is the blade 10.2 and the pressure clamp 11.2.

[0027] The shearing assembly 10 and the clamp assembly 11 are both mounted on the rotating part 7. The rotating part 7 has a shearing station and a crimping station in the stroke of rotation on the slide 4. The rotating part 7 is also mounted with a housing 18 for protecting the transmission structure of the shearing assembly 10 and the crimping assembly. When the rotating part 7 is located at the shearing station, the shearing assembly 10 is aligned with the cable clamped on the second clamp 14, and the elastic telescopic end of the elastic telescopic rod 17 is inserted into one of the limiting grooves 15, positioning the rotating part 7 at the shearing station; when the rotating part 7 is located at the crimping station, the clamp assembly 11 is aligned with the cable clamped on the second clamp 14, and the elastic telescopic end of the elastic telescopic rod 17 is inserted into the other limiting groove 15, positioning the rotating part 7 at the crimping station. When the slide 4 is located at the proximal position and the rotating part 7 is located at the shearing position, the distance a between the two blades 10.2 and the second clamping member 14 in the length direction of the slide rail 3 is closer; when the slide 4 is located at the proximal position and the rotating part 7 is located at the crimping position, the distance b between the two clamp frames 11.1 and the second clamping member 14 in the length direction of the slide rail 3 is farther, that is, a is smaller than b, in order to ensure that the subsequent crimping position is close to the middle of the exposed wire core.

[0028] The rotation switching of the rotating part 7 between the shearing station and the crimping station is realized by the one-way transmission assembly and the first driving member composed of the reduction motor and the screw rod 5. The one-way transmission assembly includes a gear 12.1, a ratchet 12.2, a pawl 12.3 and a rack 12.4. The ratchet 12.2 is embedded in the gear 12.1. The ratchet 12.2 is coaxial with the gear 12.1. The inner ring of the gear 12.1 is rotatably connected to the shaft 7.1. The pawl 12.3 is elastically hinged on the shaft 7.1 through a torsion spring. The pawl 12.3 and the ratchet 12.2 are unidirectionally engaged. The rack 12.4 is fixedly connected to the seat body 1.1. The length direction of the rack 12.4 is parallel to the moving direction of the slide 4. The rack 12.4 is located on the path where the gear 12.1 moves with the slide 4. During the movement of the slide 4, the gear 12.1 can mesh with the rack 12.4.

[0029] A first clamping member 13 for clamping a wire nose is fixedly connected to the rotating part 7. The first clamping member 13 is located near the pressure clamp assembly 11 and includes a first bracket 13.1, a first elastic clamp 13.2 and a limiting shaft 13.3. The first bracket 13.1 is fixedly connected to the guide seat 7.3 of the rotating part 7. The first elastic clamp 13.2 and the limiting shaft 13.3 are both fixedly connected to the first bracket 13.1. The cylinder of the wire nose is inserted into the first elastic clamp 13.2. The flat hole of the wire nose is sleeved on the limiting shaft 13.3. At this time, the cylinder of the wire nose is in the middle of the two pressure clamps 11.2.

[0030] A second clamping member 14 for clamping the cable is fixedly connected to the cover plate 1.2 of the seat body 1.1, and the second clamping member 14 includes a second bracket 14.1, a second elastic clamp 14.2 and a locking knob 14.3. The second bracket 14.1 is fixedly mounted on the cover plate 1.2 by a bolt pair, and the second elastic clamp 14.2 is welded to the second bracket 14.1. The cable is clamped in the second elastic clamp 14.2. When the rotating part 7 is in the shearing position, the end of the cable is located in the middle of the two blades 10.2, and the second elastic clamp 14.2 can be used to lock the cable by tightening the locking knob 14.3.

[0031] The bottom of the electric telescopic rod 9 is fixedly connected to the slide 4 through the support rod 8, and the electric telescopic rod 9 can move with the slide 4. When the rotating part 7 is located at the shearing station, the telescopic end of the electric telescopic rod 9 can abut the first contact plate 10.5 on the lower tool holder 10.1, which is equivalent to abutting the blade 10.2, so that the two blades 10.2 slide and close together to form a shearing fit; when the rotating part 7 is located at the crimping station, the telescopic end of the electric telescopic rod 9 can abut the second contact plate 11.5 on the lower clamp frame 11.1, which is equivalent to abutting the pressing clamp 11.2, so that the two pressing clamps 11.2 slide and close together to press the wire nose. Of course, the electric telescopic rod 9 can be replaced by a second driving member such as a hydraulic rod and a cylinder, which is required to be able to output linear power.

[0032] In the present invention, first, when it is only used for cutting cables, the slide 4 is located at the proximal position and the rotating part 7 is located at the cutting position, the cable is clamped in the second elastic clamp 14.2, the part to be cut is between the two blades 10.2, and the electric telescopic rod 9 is extended to squeeze one of the knife holders 10.1, so that the two blades 10.2 are synchronously closed and sheared through the cooperation of the first slider 10.3 and the two first swing rods 10.4, so that the cable can be cut, and the first return spring 10.6 is also stored. After the electric telescopic rod 9 is contracted, the elastic force of the first return spring 10.6 is released, so that the two blades 10.2 are synchronously separated.

[0033] Second, when it is only used for crimping wire noses, the slide 4 is located at the proximal station and the rotating part 7 is located at the crimping station. The cable with the wire nose already sleeved on the end is clamped in the second elastic clamp 14.2, and the wire nose is clamped in the first elastic clamp 13.2. The part to be crimped is between the two crimping clamps 11.2. The electric telescopic rod 9 is extended to squeeze one of the clamp frames 11.1, so that the two crimping clamps 11.2 are synchronously closed through the cooperation of the second slider 11.3 and the two second rocker arms 11.4, so that the end of the cable can be firmly crimped to the wire nose, and the second return spring 11.6 is also energized. After that, after the electric telescopic rod 9 is contracted, the elastic force of the second return spring 11.6 is released, so that the two crimping clamps 11.2 are synchronously separated.

[0034] Third, the most convenient and efficient method of use is to insert the cable nose into the first elastic clamp 13.2 in advance when the slide 4 is located at the proximal position and the rotating part 7 is located at the shearing position, and the flat hole of the cable nose is sleeved on the limit shaft 13.3. The cylindrical tube of the cable nose is between the two pressing clamps 11.2, and the cable is inserted into the second elastic clamp 14.2. The end of the cable extends between the two blades 10.2, and the locking handle 14.3 is tightened to fix the cable. Figure 8 ; Then, the electric telescopic rod 9 is extended a short distance, so that the two blades 10.2 are synchronously closed and sheared, and the two blades 10.2 only cut into the outer skin of the cable end, and the blades 10.2 do not cut into the cable core; then the driving motor 6 drives the slide 4 to slide in the first direction, that is, the slide 4 moves a short distance from the proximal station to the distal station along the slide rail 3, and the rotating part 7, the shearing assembly 10, the crimping assembly, the first clamping member 13, the wire nose, the electric telescopic rod 9 and the gear 12.1, the ratchet 12.2 and the pawl 12.3 of the one-way transmission assembly on the slide 4 move synchronously, The two blades 10.2 maintained in the state of cutting into the cable sheath strip the cut cable sheath from the cable core, thereby exposing the cable core; then the electric telescopic rod 9 contracts, the first return spring 10.6 causes the two blades 10.2 to separate synchronously, the drive motor 6 continues to drive the slide 4 to move to the far end station, the gear 12.1 begins to mesh with the rack 12.4, so that the gear 12.1, through the engagement of the ratchet 12.2 and the pawl 12.3, causes the rotating part 7 to rotate 180° from the shearing station to the crimping station, so that the wire nose and the cable core are in a coaxial state, as shown in FIG. Fig. 9 The driving motor 6 starts to flip and drives the slide 4 to move in the opposite direction of the first direction, that is, the slide 4 moves along the slide rail 3 from the distal station to the proximal station. During this period, on the one hand, the gear 12.1 is meshed with the rack 12.4, but the ratchet 12.2 cannot be engaged with the ratchet under the reverse rotation driven by the gear 12.1, so the rotating part 7 does not rotate. On the other hand, the slide 4 drives the first clamping member 13 to move together with the wire nose, so that the wire nose is sleeved on the cable core, such as Fig.10 Then the electric telescopic rod 9 is extended so that the two pressing clamps 11.2 are closed synchronously, and the end of the cable is firmly crimped with the wire nose. Then, after the electric telescopic rod 9 is retracted, the second return spring 11.6 separates the two pressing clamps 11.2 synchronously, and the crimped wire nose and cable can be removed from the first clamp 13 and the second clamp 14.

[0035] In the above-mentioned first and second usage methods, the opening and closing of the electric telescopic rod 9 and the opening and closing of the drive motor 6 when switching the working position of the rotating part 7 can be controlled by the buttons on the control panel 1.5, while in the third item, the opening and closing of the drive motor 6 and the opening and closing and extension amount of the electric telescopic rod 9 can be controlled by the program, and the drive motor 6 and the electric telescopic rod 9 can be automatically executed after one-button start.

[0036] The above describes some exemplary embodiments of the present invention, which should not be understood as limiting the scope of protection of the claims of the present invention. For those skilled in the art, the described embodiments can be modified in other different ways without departing from the spirit and scope of the present invention.
