Description

Technical Field

[0001] This utility model relates to the technical field of wire processing equipment, and in particular to an automatic wire stripping device. Background Technology

[0002] Chinese utility model patent with patent number ZL202422178738.9 and patent name: Circular Wire Stripping Mechanism, substantially discloses an automatic wire stripping device; the circular wire stripping mechanism specifically discloses the following technical solution: A circular wire stripping mechanism includes a base, a moving mechanism, and a stripping mechanism. An integrated fixed platform is provided above the base, and a slidably connected moving mechanism is provided on the fixed platform. One end of the moving mechanism is fixedly connected to the stripping mechanism, which is equipped with detachable blades with multiple cutting edges. The moving mechanism includes a moving cylinder and a moving platform. A first slide rail that cooperates with the moving platform is provided on the fixed platform, and a moving cylinder is provided on the moving platform. The telescopic end of the moving cylinder is fixedly connected to one end of the fixed platform. A boss is provided on the side of the moving platform away from the telescopic end of the moving cylinder, and a stripping mechanism is provided on the boss. The stripping mechanism includes a fixed block, a moving block, and a stripping cylinder. Detachable blades are provided on one side of the fixed block and the moving block. The stripping cylinder drives the moving block to move closer to or away from the fixed block to realize the opening and closing of the two blades.

[0003] During the stripping operation of the above-mentioned circular wire stripping mechanism, the end of the wire is placed between the fixed block and the moving block. The stripping cylinder drives the moving block to approach the fixed block, the blade makes a circumferential cut on the wire, and the shifting cylinder drives the moving table to move. The stripping mechanism moves synchronously with the moving table, so that the outer sheath of the wire end after the circumferential cut is removed from the wire core.

[0004] It should be noted that the above-mentioned circular wire stripping mechanism has the following defects: the moving block is started by the stripping cylinder. When the blades on the fixed block and the blades on the moving block come together to close and perform circumferential cutting on the end of the wire, the closing width of the two blades (the distance when they are closed in place) cannot be adaptively adjusted according to the outer diameter of the wire or the thickness of the outer sheath. The adjustability is poor and the adaptability is poor. Utility Model Content

Detailed Implementation

[0020] The present invention will now be described in conjunction with specific embodiments.

[0021] Example 1, as Figures 1 to 3As shown, an automatic wire stripping device includes a fixed base 1, a shifting drive mechanism 2, a translational movable frame 3, and a stripping mechanism 4. The shifting drive mechanism 2 is installed on the fixed base 1 and drives the translational movable frame 3 to move horizontally back and forth relative to the fixed base 1. The stripping mechanism 4 is installed on the translational movable frame 3.

[0022] Among them, such as Figures 1 to 3 As shown, the peeling mechanism 4 includes a left blade holder 411, a right blade holder 412, a left peeling knife 421 mounted on the left blade holder 411, and a right peeling knife 422 mounted on the right blade holder 412.

[0023] Furthermore, such as Figures 1 to 4 As shown, the peeling mechanism 4 also includes a peeling drive motor 43 that is fastened to the upper end of the translational movable frame 3, and the power output shaft of the peeling drive motor 43 is equipped with a peeling drive gear 44.

[0024] Furthermore, such as Figures 1 to 4 As shown, a drive swing arm 45 is mounted on the lower end of the peeling drive gear 44. The drive swing arm 45 includes a disc-shaped swing arm disc portion 451. The center of the swing arm disc portion 451 is rotatably mounted on the translational movable frame 3 via a rotating shaft 46. A swing arm gear portion 452 that meshes with the peeling drive gear 44 is provided on the edge of the swing arm disc portion 451. It should be explained that the swing arm disc portion 451 and the swing arm gear portion 452 in this embodiment can be an integral structure; of course, the swing arm gear portion 452 and the swing arm disc portion 451 can also be a separate structure, that is, the swing arm gear portion 452 can be assembled to the edge of the swing arm disc portion 451 by screwing.

[0025] In addition, such as Figure 3 and Figure 4 As shown, the edge of the swing arm disc portion 451 is provided with a first radial long groove 453 and a second radial long groove 454 arranged in a centrally symmetrical manner and opening radially outward respectively; the translational movable frame 3 is screwed with a guide plate 47 on the front end side of the drive swing arm 45, the left tool holder 411 and the right tool holder 412 are slidably installed on the guide plate 47 respectively, the guide plate 47 is provided with a first guide long hole 471 and a second guide long hole 472 extending horizontally in the left and right directions respectively; the left tool holder 411 is equipped with a first drive rod 481 that passes through the first guide long hole 471 and is inserted into the first radial long groove 453, and the right tool holder 412 is equipped with a second drive rod 482 that passes through the second guide long hole 472 and is inserted into the second radial long groove 454.

[0026] During the operation of the peeling mechanism 4 in this embodiment, the peeling drive motor 43 operates and drives the peeling drive gear 44 to rotate. Since the peeling drive gear 44 meshes with the swing arm gear portion 452 of the drive swing arm 45, the rotating peeling drive gear 44 drives the drive swing arm 45 to deflect. The deflecting drive swing arm 45 drives the first drive rod 481 and the second drive rod 482 to deflect through the first radial groove 453 and the second radial groove 454 of its swing arm disc portion 451, respectively. During this process, the first drive rod 481 moves along the guide... The first guide hole 471 of the guide plate 47 slides horizontally to the left and right. The second drive rod 482 slides horizontally to the left and right along the second guide hole 472 of the guide plate 47. Since the first radial groove 453 and the second radial groove 454 are centrally symmetrical structures, the first drive rod 481 and the second drive rod 482 driven by the swing arm disc 451 move synchronously in opposite directions relative to the guide plate 47, so as to drive the left knife holder 411 and the right knife holder 412 to move synchronously in opposite directions relative to the guide plate 47, thereby making the left peeling knife 421 and the right peeling knife 422 move closer or further away.

[0027] The steps involved in the wire stripping operation using the automatic wire stripping device of this embodiment include: Step a: The shifting drive mechanism 2 first moves and drives the translational movable frame 3 and the peeling mechanism 4 to move forward to the peeling position; Step b: Place the end of the wire between the left stripping blade 421 and the right stripping blade 422. Then, the stripping drive motor 43 is activated to drive the left blade holder 411 and the right blade holder 412 to move in opposite directions and close together, thereby closing the left stripping blade 421 and the right stripping blade 422. At this time, the left stripping blade 421 and the right stripping blade 422 pierce the outer sheath of the wire. Step c: After the left peeling knife 421 and the right peeling knife 422 are closed, the shift drive mechanism 2 drives the translational movable frame 3 and the peeling mechanism 4 to move backward. During this process, the left knife holder 411, the right knife holder 412, the left peeling knife 421, and the right peeling knife 422 move backward synchronously so that the cut outer skin is pulled off, thereby completing the peeling operation.

[0028] It should be emphasized that the depth to which the left stripping blade 421 and the right stripping blade 422 cut into the wire sheath can be controlled by the stripping drive motor 43. During operation, the operator can set the deflection angle of the stripping drive motor 43 through the controller, thereby controlling the closing width of the left stripping blade 421 and the right stripping blade 422. Therefore, the stripping mechanism 4 of this embodiment can adaptively adjust the closing width of the left stripping blade 421 and the right stripping blade 422 according to the outer diameter of the wire or the thickness of the sheath.

[0029] In summary, the automatic wire stripping device of this embodiment has the advantages of novel structural design, strong adjustability and strong adaptability through the above structural design.

[0030] Example 2, as Figures 1 to 3 As shown, the difference between this embodiment 2 and embodiment 1 is that: the shift drive mechanism 2 includes a shift drive motor 21 mounted on the fixed base 1, the power output shaft of the shift drive motor 21 is equipped with a shift drive gear 22, and the translational movable frame 3 is equipped with a shift drive rack 23 extending horizontally along the front-back direction, and the shift drive rack 23 meshes with the shift drive gear 22.

[0031] In the process of the displacement drive mechanism 2 driving the translational movable part to move horizontally back and forth in the second embodiment, the displacement drive motor 21 drives the translational movable frame 3 to move horizontally back and forth through the transmission pair structure composed of the displacement drive gear 22 and the displacement drive rack 23.

[0032] It should be emphasized that the shift drive motor 21 in this embodiment is electrically connected to the corresponding controller. During operation, the operator can control the shift distance by controlling the number of rotations of the shift drive motor 21, thereby adapting to different stripping length requirements and further improving the adaptability and versatility of the automatic wire stripping device in this embodiment.

[0034] During the process of the shift drive motor 21 driving the shift drive rack 23 to move back and forth through the shift drive gear 22, in this embodiment, the shift drive rack 23 is guided by the rack guide groove 241 of the rack guide block 24 to ensure the accuracy and smoothness of the shift drive rack 23 moving back and forth.

[0035] Example 4, as Figures 1 to 3 As shown, the difference between this embodiment four and embodiment one is that: the fixed base 1 is screwed with a first guide rail 251 extending in a straight line along the front and rear direction, and the translational movable frame 3 is screwed with a first slider 252 that cooperates with the first guide rail 251.

[0036] The guide rail and slider pair, consisting of the first guide rail 251 and the first slider 252, can effectively ensure the accuracy and stability of the horizontal movement of the translational movable frame 3.

[0037] Example 5, as Figures 1 to 4 As shown, the difference between this fifth embodiment and the first embodiment is that: the front surface of the guide plate 47 is screwed with a second guide rail 491 extending in a straight line in the left and right direction, and the left tool holder 411 and the right tool holder 412 are respectively screwed with a second slider 492 that cooperates with the second guide rail 491.

[0038] During the horizontal movement of the left tool holder 411 and the right tool holder 412 relative to the guide plate 47, the guide rail slider pair structure composed of the second guide rail 491 and the second slider 492 in this embodiment can effectively ensure the accuracy and stability of the horizontal movement of the left tool holder 411 and the right tool holder 412.

[0039] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
