Description

Technical Field

[0001] This utility model relates to the field of clamping fixture technology, and in particular to a clamping fixture for processing optical fiber collimators. Background Technology

[0002] Fiber optic collimators are key passive optical devices in the fields of fiber optic communication and optoelectronics. Their core function is to achieve beam collimation and coupling, playing an indispensable role in modern optical communication systems.

[0003] During the processing of fiber optic collimators, photosensitive adhesive is needed to fix the fiber optic cable and the collimator. Traditional clamping fixtures can only clamp and position the collimator. However, during the subsequent process of applying adhesive to and curing the fiber optic cable and the collimator, the operator needs to hold the fiber optic cable to ensure that the fiber optic cable and the collimator are aligned. The stability of the fiber optic cable cannot be guaranteed during the overall operation, and the operation is cumbersome and the curing efficiency cannot be guaranteed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a clamping fixture for processing fiber optic collimators.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A clamping fixture for processing an optical fiber collimator includes a base plate, a positioning block installed in the middle of the base plate, a through hole in the middle of the positioning block for placing a workpiece, a deflection seat rotatably mounted on one end of the positioning block via an extension block, a support plate installed in the middle of the deflection seat, a keyed insertion rod at one end of the support plate and inserted into a keyed insertion hole on the outer wall of the deflection seat, and a connecting screw at the other end of the support plate and screwed to an adjusting nut on the outer wall of the deflection seat.

[0007] A deflector is rotatably mounted in the middle of the extension block. A wedge-shaped block is provided at the bottom of the deflector. An arc-shaped push block is pressed against the bottom wall of the wedge-shaped block. The arc-shaped push block achieves horizontal displacement by adjusting the screw.

[0008] Furthermore, in a preferred configuration, a distance is maintained between the deflection seat and the positioning block.

[0009] In addition, a preferred structure is that a hand crank screw is screwed to the upper part of the positioning block, and the bottom of the hand crank screw extends into the positioning block and is connected to an arc-shaped pressure block.

[0010] In addition, a preferred structure is that an extension block is fixedly installed at one end of the positioning block, and an installation groove is opened in the middle of the extension block. A deflection seat is rotatably installed on one side of the installation groove via a pin. A torsion spring is provided at the rotatable connection between the deflection seat and the installation groove. When the deflection seat rotates, the torsion spring deforms.

[0011] Furthermore, in a preferred configuration, an adjusting screw is rotatably mounted inside the extension block. The two ends of the adjusting screw are smooth sections, and the threaded section in the middle extends into the mounting groove and is screwed into the arc-shaped push block. The arc-shaped push block is slidably mounted in the mounting groove.

[0012] In addition, a preferred structure is that the bottom of the deflection seat is provided with a wedge-shaped block, which extends into the mounting groove and presses against the upper wall of the arc-shaped push block.

[0013] In addition, a preferred structure is that the deflection seat has a keyway insertion hole in the middle of one side and a through hole in the other side, and an adjusting nut is rotatably installed on the side away from the through hole via a bearing component.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this invention, the fiber optic collimator and fiber optic component are positioned using a positioning block and a support plate. The support plate achieves horizontal displacement by rotating the adjusting nut, and the angle of the support plate is adjusted by rotating the adjusting screw to drive the arc-shaped push block to press the deflection seat to different degrees. Through multiple adjustment mechanisms, the position of the fiber optic component is adjusted and positioned, ensuring the connection stability between the fiber optic component and the fiber optic collimator, ensuring stability during the curing process, preventing the fiber optic component from falling off or shifting, and effectively improving work efficiency.

Detailed Implementation

[0022] 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.

[0023] Reference Figure 1-5 A clamping fixture for processing an optical fiber collimator includes a base plate 1, a positioning block 2 installed in the middle of the base plate 1, a through hole in the middle of the positioning block 2 for placing an optical fiber collimator, a deflection seat 5 rotatably installed at one end of the positioning block 2 via an extension block 4, and a support plate 6 installed in the middle of the deflection seat 5 for supporting optical fiber components.

[0024] One end of the support plate 6 is provided with a keyed insert rod 61, which is inserted into the keyed insertion hole 54 on the outer wall of the deflection seat 5. The other end of the support plate 6 is provided with a connecting screw 62, which is screwed to the adjusting nut 53 on the outer wall of the deflection seat 5.

[0025] A deflector seat 5 is rotatably mounted in the middle of the extension block 4. A wedge block 51 is provided at the bottom of the deflector seat 5. An arc-shaped push block 71 is pressed against the bottom wall of the wedge block 51. The arc-shaped push block 71 achieves horizontal displacement by adjusting the screw 7.

[0026] There is a distance between the deflection seat 5 and the positioning block 2.

[0027] A hand crank screw 3 is screwed to the upper part of the positioning block 2. The bottom of the hand crank screw 3 extends into the positioning block 2 and is connected to an arc-shaped pressure block 31. By rotating the hand crank screw 3, the arc-shaped pressure block 31 is moved through the screw thread, thereby achieving the clamping and positioning of the workpiece.

[0028] An extension block 4 is fixedly installed at one end of the positioning block 2. An installation groove 41 is provided in the middle of the extension block 4. A deflection seat 5 is rotatably installed on one side of the installation groove 41 via a pin. A torsion spring 52 is provided at the rotatable connection between the deflection seat 5 and the installation groove 41. When the deflection seat 5 rotates, the torsion spring 52 deforms to generate torsional force.

[0029] In its natural state, the torsion spring 52 drives the deflector seat 5 to deflect downwards, that is, towards a point in the mounting groove 41, thereby pressing it against the arc-shaped push block 71.

[0030] An adjusting screw 7 is rotatably installed inside the extension block 4. Both ends of the adjusting screw 7 are smooth sections. One end is rotatably installed inside the mounting groove 41, and the other end extends out of the outer wall of the extension block 4.

[0031] The threaded section of the adjusting screw 7 extends into the mounting groove 41 and is screwed into the middle of the arc-shaped push block 71. The arc-shaped push block 71 is limited and slidably installed in the mounting groove 41 to achieve horizontal displacement.

[0032] The bottom of the deflection seat 5 is provided with a wedge block 51, which extends into the mounting groove 41 and presses against the upper wall of the arc-shaped push block 71.

[0033] The deflection seat 5 has a keyway insertion hole 54 in the middle of one side and a through hole in the other side. An adjusting nut 53 is rotatably installed on the side away from the through hole via a bearing component.

[0034] The bottom of the keyway insertion hole 54 is provided with a keyway. The keyway insertion hole 54 and the key block insertion rod 61 are interlocking mechanisms. The bottom of the key block insertion rod 61 is provided with a key block to mate with the keyway. The horizontal displacement of the support plate 6 is achieved through the keyway.

[0035] The keyway is open at both ends to allow for key block movement.

[0036] In this embodiment, the fiber collimator is placed in the mounting through hole in the middle of the positioning block 2, and the hand crank screw 3 is rotated to drive the arc-shaped pressure block 31 to press and position the workpiece.

[0037] The optical fiber component is supported by the support plate 6 on the upper part of the extension block 4. Before the adhesive curing process, the adjusting screw 7 is rotated to drive the arc-shaped push block 71 to move horizontally. When the arc-shaped push block 71 moves, it will press and contact the wedge block 51 at the bottom of the deflection seat 5. Under the guidance of the inclined surface of the wedge block 51, the deflection seat 5 is driven to deflect. After the deflection, the deflection seat 5 will drive the optical fiber component placed on the support plate 6 to move. The adjusting screw 7 is rotated according to the actual processing situation to achieve different degrees of displacement of the optical fiber component, so as to ensure that the optical fiber component will not sag or shift during the curing process.

[0038] The adjusting nut 53 can still be rotated. The adjusting nut 53 rotates through the thread to drive the internally screwed connecting screw 62 to move. The connecting screw 62 simultaneously drives the support plate 6 to produce a horizontal displacement, so as to facilitate the horizontal adjustment of the optical fiber component.

[0039] During the movement of the pallet 6, the keyed insert rod 61 slides within the keyed insertion hole 54 on the outer wall of the deflection seat 5.

[0040] The side of the connecting screw 62 facing the support plate 6 is a smooth section, which passes through the deflection seat 5.

[0041] The threaded section passes directly through the deflector seat 5 after being displaced by the support plate 6.

[0042] Among them, the torsion spring 52 drives the deflection seat 5 to always press against the arc-shaped push block 71.

[0043] After the workpiece is positioned, the photosensitive adhesive is cured by UV light.

[0044] It is worth noting that the application and curing processes of the photosensitive adhesive, which were not explained in detail above, are common knowledge to those skilled in the art and will not be explained further.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
