[0030] 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.

[0031] See also Figure 1-Figure 9The embodiment of the present invention provides a cable nose secondary automatic crimping pliers, comprising a base 1, a slide 2, a first driving member, a second driving member, and a corresponding fixed jaw 3 and movable jaw 4; the slide 2 is slidably connected to the base 1 along the first direction, and the slide 2 has a first station and a second station in the sliding stroke on the slide, the fixed jaw 3 is fixedly arranged on the slide 2, and the movable jaw 4 is slidably connected to the slide 2 along the second direction. Specifically, a slide groove 21 is provided on the slide 2 along the second direction, and the fixed jaw 3 and the movable jaw 4 are both slidably arranged in the slide groove 21. The fixed jaw 3 is locked to the slide 2 by a locking bolt 18, and different models of fixed jaws 3 and movable jaws 4 can be easily replaced. It should be noted that the second direction is perpendicular to the first direction. The first driving member is used to drive the movable jaw 4 to slide on the slide 2, and the second driving member is used to drive the slide 2 to slide to switch between the first station and the second station.

[0032] Specifically, the first driving member is an electric push rod 7, the seat of which is fixedly mounted on the base 1, and a pressure block 6 is fixedly connected to the power output end thereof. Of course, the electric push rod 7 can be replaced by a linear drive mechanism such as a hydraulic cylinder, a pneumatic cylinder or a linear motor. The pressure block 6 is in abutment with the movable jaw 4 in the second direction and slides in the first direction: for example, the back side of the movable jaw 4 is magnetically engaged with the pressure block 6; or a slide rail is provided on the pressure block 6, and the movable jaw 4 is slidably connected to the slide rail along the second direction; or the pressure block 6 is a split structure, which includes a fixed block fixedly connected to the power output end of the electric push rod 7 and a sliding block slidably connected to the fixed block along the second direction, and the movable jaw 4 is fixedly connected to the sliding block.

[0033] In the above technical scheme, the present invention provides a cable nose secondary automatic crimping pliers, which aligns the to-be-crimped portion of the cable nose with the fixed jaw 3 on the slide 2 located at the first station, and then the first driving member drives the movable jaw 4 to slide close to the fixed jaw 3 to crimp the cable nose once and slide away from the fixed jaw 3, and then the second driving member drives the slide 2 to slide to the second station so that the fixed jaw 3 and the movable jaw 4 are offset from the first crimping portion of the cable nose in the first direction, and then the movable jaw 4 slides close to the fixed jaw 3 again to crimp the cable nose at a new position. In use, the operator only needs to fix the cable nose to be crimped, and then the present invention can automatically perform a crimping and change the crimping position for a second crimping, so that the cable nose is crimped twice in succession at different positions, which not only improves the connection strength of the cable, but also improves the convenience of the operator's operation.

[0034] As a preferred technical solution of the present invention, a clamp 5 aligned with the fixed jaw 3 is provided on the base 1, and the clamp 5 is used to clamp the cable nose to be crimped, that is, the crimping connection between the cable and the nose, and the clamp 5 clamps the cable and / or the nose. Specifically, the clamp 5 includes two relatively distributed clamping units, each of which includes an elastic rod 51, an arc-shaped portion 52 and an inclined guide rod 53 connected in sequence, the end of the elastic rod 51 is fixedly connected to the base 1, and the elastic force of the elastic rod 51 of the two clamping units makes the two arc-shaped portions 52 fit together, and the axial direction of the arc-shaped portion 52 is parallel to the first direction. The cable nose is pressed between the two arc-shaped portions 52 under the guidance of the inclined guide rod 53 for clamping and fixing, and the axial direction of the cable nose is along the first direction. In the present technical solution, when in use, the operator only needs to press the cable nose to be crimped into the clamp 5 to fix it, and then the present invention can automatically perform a first crimping and change the crimping position for a second crimping. After the crimping is completed, the operator can remove the cable nose from the clamp 5, which greatly facilitates the operator's operation.

[0035] Regarding the selection of the second driving member, in one embodiment, the second driving member is an active component, including another electric push rod (not shown in the figure) installed on the base 1, the base of the electric push rod is fixedly installed on the base 1, and its power output end is fixedly connected to the slide 2. Of course, the electric push rod can be replaced by a linear drive mechanism such as a hydraulic cylinder, a pneumatic cylinder or a linear motor.

[0036] In this embodiment, the electric push rod of the second driving member and the electric push rod 7 of the first driving member are opened and closed by the staff through the switch respectively; or, the electric push rod of the second driving member and the electric push rod 7 of the first driving member are linked to each other, that is, after the operator starts the cable nose secondary automatic crimping pliers, the first driving member drives the movable jaw 4 to slide close to the fixed jaw 3 to crimp the cable nose once and slide away from the fixed jaw 3, the second driving member automatically starts to drive the slide 2 to slide to the second station and then automatically closes, and then the first driving member automatically starts to drive the movable jaw 4 to slide close to the fixed jaw 3 again to crimp the cable nose for a second time, the first driving member automatically drives the movable jaw 4 to slide away from the fixed jaw 3 for reset, and finally the first drive automatically starts to drive the slide 2 to slide and reset to the first station. During the whole process, the operator only needs to press the start button.

[0037] Regarding the selection of the second driving member, in another embodiment, the second driving member is a passive component, including a first spring, a distribution block 9, a rotating rod 11, a sliding column 13 and a locking member, wherein one end of the first spring is connected to the base 1, and the other end is connected to the slide 2, and the elastic force of the first spring acts on the slide 2, and the direction of the elastic force is the direction in which the slide 2 slides from the second station to the first station. Of course, the first spring can be replaced by other first elastic members 8, and the process of the first elastic member 8 restoring the deformation drives the slide 2 to move from the second station to the first station. The distribution block 9 is fixedly connected to one side of the slide 2, and there is a guide groove 10 between the distribution block 9 and the slide 2, and the length direction of the guide groove 10 is the second direction. The slide 2 is provided with a groove 12, and the rotating rod 11 is rotatably connected to the slide 2. During the rotation of the rotating rod 11 relative to the slide 2, there are: a guide position that closes the guide groove 10 and tilts against the distribution block 9, and an avoidance position that rotates into the groove 12 to avoid the slide post 13 that slides out of the guide groove 10. A torsion spring (not shown in the figure) is sleeved on the rotating shaft between the rotating rod 11 and the slide 2, one end of the torsion spring is connected to the slide 2, and the other end is connected to the rotating rod 11. The elastic force of the torsion spring can make the rotating rod 11 rotate from the avoidance position to the guide position. Of course, the torsion spring can be replaced by other second elastic members, and the second elastic member is required to restore the deformation process to drive the rotating rod 11 to rotate from the avoidance position to the guide position. The slide post 13 is fixedly connected to the pressing block 6 through the connecting rod 14. The slide post 13 can move along the guide groove 10, and can also move outside the guide groove 10 to the side of the distribution block 9 away from the guide groove 10.

[0038] When the slide 2 slides to the second station, the slide 2 can be locked in the second station by the locking member. Specifically, the locking member includes a latch 15, a stopper 16 and a third spring. The latch 15 is fixedly connected to the stopper 16, and the base 1 is fixedly connected to the support rod 19. The latch 15 is fixedly connected to a slide rod 20, and the slide rod 20 is slidably connected to the support rod 19, that is, the latch 15 is slidably connected to the base 1 along the second direction. The elastic force of the third spring acts on the latch 15 along the second direction, and the direction of the elastic force is the direction in which the latch 15 approaches the fixed jaw 3. Of course, the third spring can be replaced by other third elastic members 17, and the process of restoring the deformation of the third elastic member 17 drives the process of restoring the deformation to drive the latch 15 to be inserted into the guide groove 10. When the slide 2 is located at the second station, the slide post 13 slides along the side of the dividing block 9 away from the guide groove 10 and away from the fixed jaw 3 and passes over the dividing block 9 . Then, the slide post 13 can abut against the blocking rod 16 to make the latch 15 withdraw from the guide groove 10 .

[0039] In this embodiment, the portion of the cable nose to be crimped is aligned with the fixed jaw 3 on the slide 2 located at the first station, and is pressed into the fixture 5 for locking. In the initial state, the slide 2 is located at the first station, and the elastic force of the first spring can keep the slide 2 at the first station. The movable jaw 4 and the fixed jaw 3 are in a separated state, and the slide post 13 is located outside the guide groove 10 and is aligned with the guide groove 10 in the second direction. The rotating rod 11 is maintained in the guiding position of the closed guide groove 10 under the elastic force of the torsion spring, the latch 15 is in a misaligned state with the guide groove 10, and the third spring is in a compressed energy storage state due to the abutment with the end surface of the slide 2 and / or the abutment of the slide post 13 on the baffle rod 16, see Figure 1-Figure 3 Then the electric push rod 7 of the first driving member pushes the movable jaw 4 to slide closer to the fixed jaw 3 along the second direction through the pressure block 6, and the pressure block 6 drives the slide column 13 to enter the guide groove 10, and the slide column 13 squeezes the rotating rod 11 to rotate the rotating rod 11 from the wire position to the avoidance position, and the torsion spring is forced to deform and store energy, see Figure 5 Then the movable jaw 4 cooperates with the fixed jaw 3 to crimp the cable nose under the continued push of the pressure block 6. At this time, the slide column 13 also completely passes over the rotating rod 11, and the elastic force of the torsion spring is released, so that the rotating rod 11 rotates from the avoidance position to the guide position, see Figure 6 Then, the electric push rod 7 of the first driving member drives the movable jaw 4 and the slide column 13 to slide away from the fixed jaw 3 along the second direction through the pressure block 6, and the movable jaw 4 releases the crimping of the cable nose. Due to the blocking of the guide groove 10 by the rotating rod 11, the slide column 13 moving away from the fixed jaw 3 along the second direction squeezes the inclined rotating rod 11 to make the slide 2 slide from the first station to the second station. The first spring is compressed and stores energy. When the slide column 13 is attached to the side of the distribution block 9 away from the guide groove 10, the electric push rod 7 stops driving the pressure block 6 to move, and the slide 2 slides The slide 2 moves to the second station. On the one hand, the fixed jaws 3 and the movable jaws 4 on the slide 2 are staggered from the first crimping position of the cable nose in the first direction and aligned with the new position of the cable nose. The movable jaws 4 are displaced relative to the pressure block 6 in the first direction, but the pressure block 6 can still maintain contact with the movable jaws 4. On the other hand, the guide groove 10 on the slide 2 is just aligned with the latch 15, and the elastic force of the third spring is released, so that the latch 15 is inserted into the guide groove 10, thereby locking the slide 2 in the first direction, that is, the slide 2 is locked in the second station. Figure 7 Next, the electric push rod 7 of the first driving member drives the movable jaw 4 and the slide post 13 to move toward the fixed jaw 3 through the pressure block 6 again. Since the latch 15 locks the slide 2 in the first direction, even if the slide post 13 is separated from the abutment on the side of the distribution block 9 away from the guide groove 10, the elastic force of the first spring will not push the slide 2 back to the first position, and the movable jaw 4 will move to cooperate with the fixed jaw 3 to perform secondary crimping of the cable nose in the new position, see Figure 8Finally, the electric push rod 7 of the first driving member drives the movable jaw 4 and the slide post 13 to slide away from the fixed jaw 3 along the second direction through the pressure block 6. After the slide post 13 slides over the dividing block 9 along the side away from the guide groove 10, the slide post 13 abuts against the blocking rod 16 and moves together, so that the latch 15 withdraws from the guide groove 10 and compresses the third spring to store energy. Fig. 9 At this time, the elastic force of the first elastic member 8 is released, and the slide 2 is immediately driven to slide from the second station to the first station, and the present invention is reset to the initial state, that is, Figure 1-Figure 3 In the state shown, the cable lug is crimped twice in succession at different positions, and a complete crimping cycle is completed. The operator can take away the crimped cable lug, such as removing it from the clamp 5.

[0040] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
