DETAILED DESCRIPTION
[0019] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0020] Example
[0021] like Figure 1-4 As shown, the utility model proposes an optical fiber cutting device, including a base 1, a flap 2, a hinge 3 and a controller 4, wherein the two hinges 3 are symmetrically mounted on the back wall of the base 1 and the flap 2, and the flap 2 can be flipped with the assistance of the hinge 3 through the arrangement of the hinge 3, so that the optical fiber can be conveniently placed on the base 1; the controller 4 is fixedly mounted on one side wall of the base 1; the knife seat 9 is fixedly mounted on the bottom inner wall of the base 1, and the second cylinder 10 is fixedly mounted on the top wall of the flap 2, and three sliding holes are provided on the top wall of the flap 2, and the output end of the second cylinder 10 passes through the sliding hole in the middle position and is connected to the top of the cutting blade 11 arranged in the flap 2, and the position of the cutting blade 11 corresponds to the position of the knife seat 9, and then the cutting blade 11 is pushed down by starting the second cylinder 10, and the optical fiber can be cut in cooperation with the knife seat 9.
[0022] Furthermore, a support assembly 5 for supporting the optical fiber is symmetrically arranged on the bottom inner wall of the base 1. The support assembly 5 includes a limited support seat 51, which is arranged in the base 1. A through hole is opened in the limited support seat 51, and a guide rod 52 is arranged in the through hole. The two ends of the guide rod 52 are respectively welded to the side wall of the knife seat 9 and the inner wall of the base 1, so as to assist the movement of the limited support seat 51; a spring 53 is sleeved on the guide rod 52, and the other end of the spring 53 is connected to the side wall of the limited support seat 51, and one end is connected to the side wall of the knife seat 9, so as to drive the limited support seat 51 to reset conveniently.
[0023] Furthermore, a clamping assembly 6 is symmetrically mounted on the flip cover 2 for facilitating the clamping and positioning of the optical fiber in cooperation with the supporting assembly 5. The clamping assembly 6 includes a first cylinder 61, which is fixedly mounted on the top wall of the flip cover 2. The output end of the first cylinder 61 passes through a slide hole corresponding to the position and is connected to an auxiliary plate 62 arranged in the flip cover 2, so as to facilitate the lifting and lowering of the auxiliary plate 62. The movable seat 63 is in an inverted convex shape, and the clamp 64 is fixedly mounted on the bottom wall of the movable seat 63. The protruding parts on both sides of the movable seat 63 are arranged in the limiting slide grooves provided in the auxiliary plate 62. The shape of the movable seat 63 can make the movable seat 63 move in the limiting slide groove, and can also prevent the movable seat 63 from being separated from the auxiliary plate 62, so as to avoid affecting the first cylinder 61. The height of the movable seat 63 is adjusted. When the optical fiber is placed at the limiting part of the limiting support seat 51, the first cylinder 61 is started to push the auxiliary plate 62 to drive the movable seat 63 and the chuck 64 to descend, so that the chuck 64 cooperates with the limiting support seat 51 to achieve the clamping and positioning of the optical fiber, and prevent the optical fiber from moving during the subsequent cutting process. At the same time, when the optical fiber is pressurized by the cutting blade 11, the chuck 64 cooperates with the limiting support seat 51, which is conducive to movement under pressure, and prevents the optical fiber from breaking at the clamping point of the chuck 64 and the limiting support seat 51 during the process of cutting the optical fiber by the cutting blade 11, which affects the cutting work. In addition, under the movable setting of the limiting support seat 51 and the chuck 64, the cutting accuracy is improved and the risk of its breakage is reduced.
[0024] Further, a limiting assembly 7 is installed on the front wall of the base 1 to facilitate the limiting of the flip cover 2. The limiting assembly 7 includes a first arc plate 71, which is welded on the front wall of the base 1, and a clamp 72 is welded on the top wall of the first arc plate 71; a locking assembly 8 is installed on the front wall of the flip cover 2 to cooperate with the limiting assembly 7 to complete the positioning of the flip cover 2, and the locking assembly 8 includes a second arc plate 81, which is welded on the front wall of the flip cover 2, a rotating cylinder 82 is arranged in the central hollow part of the second arc plate 81, a collar 83 is sleeved on the outer ring surface of the rotating cylinder 82, and a second rotating groove is opened on the hollow inner wall of the second arc plate 81, and the sleeve The ring 83 is arranged in the second rotating groove. Through the cooperation of the ring 83 and the second rotating groove, the rotating drum 82 can be rotated on the second curved plate 81, and in the process of rotation, it is helpful to prevent the rotating drum 82 from separating from the second curved plate 81 to avoid affecting subsequent use; when the flip cover 2 is spliced with the base 1, the protrusions on both sides of the clamping head 72 are respectively inserted into the vertical grooves on the inner wall of the rotating drum 82. When the splicing is completed, the protrusions of the clamping head 72 enter the first rotating groove on the inner wall of the rotating drum 82. At this time, the rotating drum 82 is rotated so that the protrusions of the clamping head 72 are staggered with the vertical grooves in the rotating drum 82, thereby completing the restriction on the flip cover 2 and preventing the flip cover 2 from being flipped up during the cutting process to affect the cutting of the optical fiber.
