Description

Technical Field

[0001] This utility model relates to the field of optical fiber processing equipment technology, and in particular to an auxiliary cutting device for optical fiber end face. Background Technology

[0002] Fiber optic cleaving is a crucial process in fiber optic communication, fiber optic sensing, and other fields. The flatness of the cleaved fiber end face directly affects the connection loss and transmission performance of the fiber. Currently, most existing fiber optic cleaving equipment uses fixed clamps to hold the fiber and a cleaver to perform the cleaving operation. However, this method still has many shortcomings in practical applications. For example, it lacks real-time support for the fiber end face during the cleaving process, and the fiber end is prone to shaking, affecting the cleaving accuracy. Therefore, this paper presents an auxiliary cleaving device for fiber end face. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides an auxiliary cutting device for optical fiber end faces. The device achieves stable clamping of the optical fiber through the cooperation of a V-groove and a clamping block. Simultaneously, it utilizes a downward-moving protrusion and its bottom optical fiber bayonet to precisely limit and support the optical fiber end. The cutting head can also move along a U-shaped limiting sleeve, effectively preventing optical fiber displacement or end-face wobbling during cutting, ensuring the flatness of the optical fiber end face, reducing subsequent connection losses, and overcoming the deficiencies of existing technologies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An auxiliary cutting device for optical fiber end faces includes a base, a support fixed to the top of the base, a V-groove provided in the middle of the top of the support, a vertical plate fixed to one end of the support, an insertion hole in the middle of the vertical plate communicating with the bottom end of the V-groove, a sliding groove provided on the outer side of the vertical plate above the insertion hole, an L-shaped support rod fixed to the top of the vertical plate, a first screw screwed to the horizontal section of the L-shaped support rod, a movable rod rotatably mounted on the lower end of the first screw rod via a bearing, a protrusion provided in the middle of the bottom end of the movable rod, a cutting assembly provided on the horizontal section of the L-shaped support rod, and a clamping assembly provided at the top of the support.

[0005] As a further improvement of this utility model: the outer wall of the protrusion matches the insertion hole, and the bottom end of the protrusion is provided with an optical fiber bayonet.

[0006] As a further embodiment of this utility model: the cutting assembly includes an electric push rod installed on the lower end face of the horizontal section of the L-shaped support rod, and a cutting head is connected to the lower end of the electric push rod.

[0007] As a further improvement of this utility model: a U-shaped limiting sleeve is fixed to the outer wall of the vertical plate, and the cutting head is movably inserted into the inner side of the U-shaped limiting sleeve.

[0008] As a further embodiment of this utility model: the clamping assembly includes a U-shaped rod fixed to the top of the support, a second screw is screwed to the middle of the horizontal section of the U-shaped rod, and a clamping block adapted to the V-groove is rotatably mounted on the lower end of the second screw through a bearing.

[0009] As a further improvement of this utility model: the top two sides of the clamping block are provided with slots, and the two slots are slidably engaged with the vertical sections on both sides of the U-shaped rod.

[0010] As a further improvement of this utility model, a waste material chute is installed at the bottom of the outer wall of the vertical plate and below the insertion hole.

[0011] As a further improvement of this utility model: a waste collection trough is provided at the top of the base and below the waste chute, and mounting holes are provided at the four corners of the base.

[0012] The beneficial effects of this utility model are as follows: 1. The V-groove and clamping block work together to securely hold the optical fiber.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1, referring to Figure 1-4 An auxiliary cutting device for fiber optic end faces includes a base 1, a support 2 fixed to the top of the base 1, a V-groove 3 provided in the middle of the top of the support 2, a vertical plate 7 fixed to one end of the support 2, an insertion hole 15 provided in the middle of the vertical plate 7 communicating with the bottom end of the V-groove 3, a sliding groove 14 provided on the outer side of the vertical plate 7 and above the insertion hole 15, an L-shaped support rod 13 fixed to the top of the vertical plate 7, a first screw 20 screwed to the horizontal section of the L-shaped support rod 13, a movable rod 17 rotatably mounted on the lower end of the first screw 20 through a bearing, a protrusion 18 provided in the middle of the bottom end of the movable rod 17, a cutting component provided on the horizontal section of the L-shaped support rod 13, and a clamping component provided at the top of the support 2.

[0021] The outer wall of the protrusion 18 matches the socket 15, and the bottom end of the protrusion 18 is provided with an optical fiber bayonet 16.

[0022] The cutting assembly includes an electric push rod 12 installed on the lower end of the horizontal section of the L-shaped support rod 13. The lower end of the electric push rod 12 is connected to a cutting head 8. The cutting head 8 and the electric push rod 12 can be connected by a flange. If wear and dulling occur, the cutting head 8 should be replaced in time to ensure cutting quality.

[0023] A U-shaped limiting sleeve 9 is fixed to the outer wall of the vertical plate 7, and the cutting head 8 is movably inserted into the inner side of the U-shaped limiting sleeve 9.

[0024] The clamping assembly includes a U-shaped rod 5 fixed to the top of the support 2, a second screw 6 screwed to the middle of the horizontal section of the U-shaped rod 5, and a clamping block 4 adapted to the V-groove 3 rotatably mounted on the lower end of the second screw 6 via a bearing.

[0025] The top two sides of the clamping block 4 are provided with slots 19, and the two slots 19 are respectively slidably engaged with the vertical sections on both sides of the U-shaped rod 5.

[0026] A waste chute 10 is installed at the bottom of the outer wall of the vertical plate 7 and below the insertion hole 15, and a waste collection trough 11 is provided at the top of the base 1 and below the waste chute 10.

[0027] Place the optical fiber to be cut into the V-groove 3 at the top of the support 2, and pass one end of the optical fiber through the insertion hole 15 on the vertical plate 7 so that the end of the optical fiber extends to the outside of the vertical plate 7 to a suitable cutting length. At this time, it is necessary to ensure that the optical fiber is in a straight state in the V-groove 3. Rotate the second screw 6 on the U-shaped rod 5. Since the second screw 6 is screwed to the U-shaped rod 5 and the clamping block 4 is slidably engaged with the vertical section of the U-shaped rod 5 through the slot 19, the rotation of the second screw 6 will drive the clamping block 4 to move down in the vertical direction until the clamping block 4 cooperates with the V-shaped groove 3 to firmly clamp the optical fiber and prevent the optical fiber from shifting during the cutting process. Rotating the first screw 20 on the L-shaped support rod 13 will push the movable rod 17 down, causing the protrusion 18 at the bottom of the movable rod 17 to be inserted into the insertion hole 15. At the same time, the fiber optic bayonet 16 at the bottom of the protrusion 18 engages with the outer wall of the fiber optic cable, providing limiting support for the fiber optic end and preventing the fiber optic end from shaking during cutting, thereby improving cutting accuracy. The electric push rod 12 is activated by the control switch installed on the base 1. The electric push rod 12 drives the cutting head 8 to move down along the guide direction of the U-shaped limit sleeve 9. The cutting head 8 contacts and cuts the optical fiber, completing the cutting operation of the optical fiber end face. The optical fiber waste generated by cutting will fall into the waste chute 10 and slide into the waste collection trough 11 along the waste chute 10 for easy subsequent unified cleaning. After cutting, first control the electric push rod 12 to drive the cutting head 8 to reset, then rotate the first screw 20 in the opposite direction to make the protrusion 18 disengage from the socket 15, and then rotate the second screw 6 in the opposite direction to make the clamp 4 move up to release the optical fiber, so that the cut optical fiber can be taken out for subsequent end face processing or connection operations.

[0028] Example 2 is an optimization based on Example 1, specifically: Mounting holes are provided at all four corners of the base 1. The mounting holes at the four corners of the base 1 can be used with bolts to fix the entire equipment on the workbench, ensuring the overall stability of the equipment during cutting operations.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
