[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figure 1-Figure 5As shown, the utility model provides a crimping device for power engineering construction, including a box body 1, a box door 5 movably connected to the rear side of the box body 1, a docking pipe 7 fixedly connected to the front side of the box body 1, a mounting frame 3 fixedly installed inside the box body 1, and the box body 1 includes a crimping mechanism 4 for crimping and a snap mechanism 8 for quick replacement;

[0029] The butt joint 7 is internally connected to the outer shell 41 by a snap-fit, and limit grooves 410 are provided on both sides of the inner wall of the outer shell 41. A servo motor 6 is provided inside the box body 1, and a worm 42 is fixedly sleeved on the output shaft of the servo motor 6. A worm gear 43 is meshed and installed on the outer surface of the worm 42. A rotating ring 44 is fixedly connected to one side of the worm gear 43, and a hexagonal groove 45 is provided inside the rotating ring 44. Several sliders 46 are slidably connected inside the hexagonal groove 45. The slider 46 is fixedly connected to a corner of the pressure block 47, and a connecting block 48 is fixedly connected to one side of the pressure block 47. A limit rod 49 is fixedly connected to the inside of the connecting block 48, and both ends of the limit rod 49 are slidably connected to the inner wall of the limit groove 410.

[0030] In this embodiment, when it is necessary to crimp cables of different specifications, the staff first feeds the cable to be processed from the docking tube 7 into the outer shell 41, and then starts the servo motor 6 inside the box 1. The output shaft of the servo motor 6 drives the worm 42 to rotate, and the rotation of the worm 42 drives the worm gear 43 to rotate counterclockwise, and the worm gear 43 drives the rotating ring 44 on one side to rotate counterclockwise. When the rotating ring 44 rotates, several sliders 46 slide in the hexagonal groove 45. While the slider 46 slides, it drives the pressure block 47 to move. During the movement of the pressure block 47, the limiting rod 49 slides in the limiting groove 410 through the connecting block 48, thereby limiting the movement direction of the pressure block 47 to a certain extent, ensuring the stability and accuracy of the movement of the pressure block 47, and making several pressure blocks 47 move synchronously toward the center of the rotating ring 44, thereby realizing accurate and stable crimping operation of the cable to be processed placed in the outer shell 41. This design can crimp cables of different specifications, reduces the time for equipment debugging and preparation, improves work efficiency, and improves the versatility of the device.

[0031] In a further embodiment, a docking groove 31 is opened inside the mounting frame 3, the outer shell 41 is slidably connected to the inner wall of the docking groove 31, and a card slot 84 is opened at both the upper and lower ends of the mounting frame 3, and a card seat 83 is fixedly connected to the upper and lower ends of the outer shell 41. A handle 81 is fixedly connected to one side of the card seat 83, and the card seat 83 is slidably connected to the inner wall of the card slot 84.

[0032] In this embodiment, when the shell 41 needs to be installed for crimping operation, the staff uses the handle 81 to align the shell 41 and the card seat 83 with the docking groove 31 and the card groove 84 opened inside the mounting frame 3 respectively, and then pushes the shell 41 to slide it into the inner wall of the docking groove 31 to achieve the purpose of preliminary installation of the shell 41.

[0033] In a further embodiment, a pressure rod groove 87 is horizontally opened inside the holder 83 , and a latch tongue groove 89 is vertically opened inside the holder 83 .

[0034] In this embodiment, the pressure rod groove 87 allows the pressure rod 82 to slide inside it, and the tongue groove 89 allows the tongue 85 to slide inside it, and the two provide activity space for related components to achieve the locking or unlocking function.

[0035] In a further embodiment, a pressure rod 82 is slidably connected to the interior of the pressure rod groove 87 , and one end of the pressure rod 82 passes through the top of the handle 81 and extends to the outside of the handle 81 .

[0036] In this embodiment, the pressure rod 82 passes through the handle 81, so that the operator can conveniently press the pressure rod 82 with his fingers while holding the handle 81 to quickly install and disassemble the shell 41 without having to look for additional tools or perform complicated operating procedures, thereby greatly shortening the replacement time of the shell 41.

[0037] In a further embodiment, one end of the pressure rod 82 is movably connected to a spring 86 , and one end of the spring 86 is fixedly connected to an end wall of the pressure rod groove 87 .

[0038] In this embodiment, when the pressure rod 82 is pressed to unlock the connection between the card holder 83 and the card slot 84, the spring 86 is in a compressed state. Once the pressure rod 82 is released, the elasticity of the spring 86 will push the pressure rod 82 back to the initial position, preparing for the next operation. There is no need to manually restore the pressure rod 82 to the initial position, which greatly improves the operating efficiency.

[0039] In a further embodiment, a bevel block 88 is fixedly installed inside the slot near one end of the pressure rod 82 near the spring 86, and a tongue 85 is movably sleeved on the outer surface of the bevel block 88. The tongue 85 is slidably connected to the inner wall of the tongue slot 89, and the top of the tongue 85 is slidably connected to the top slot of the slot 84.

[0040] In this embodiment, when the crimping mechanism 4 needs to be replaced, the pressure rod 82 is pressed, and the inclined block 88 moves with the pressure rod 82, applying a lateral extrusion force to the tongue 85 through the inclined surface, forcing the tongue 85 to enter the tongue groove 89, thereby quickly releasing the lock, making the operation of replacing the shell 41 more efficient, saving working time and improving work efficiency.

[0041] In a further embodiment, a mounting plate 2 is fixedly mounted on one side of the interior of the box 1 , and a servo motor 6 is fixedly mounted on the top of the mounting plate 2 .

[0042] In this embodiment, the mounting plate 2 provides a stable mounting platform for the servo motor 6 , ensuring that the servo motor 6 does not shake or shift during operation, thereby ensuring the normal operation of the device.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
