Technical Field

[0001] This utility model relates to the field of optical fiber adapter manufacturing technology, and specifically to an optical fiber interface component pressing device. Background Technology

[0002] Fiber optic adapters are key components used for connecting optical communication devices. They typically include metal parts, ceramic cores, and sleeves. The metal parts, as fiber optic interface components, are generally assembled by pressing together upper and lower metal elements.

[0003] Currently, most metal component assembly and pressing devices for fiber optic adapters require two sets of drive components: one is a horizontal drive component used to drive the clamp to slide horizontally and clamp the metal component, and the other is a vertical drive component used to drive the pressure rod to lift vertically and press the upper metal component onto the lower metal component. The structure is relatively complex and the cost is high.

[0004] Therefore, there is room for improvement and development in existing technologies. Utility Model Content

[0005] To address the problems of existing technologies, this utility model proposes a fiber optic interface component pressing device, which enables a set of drive components to both slide the gripper component horizontally and raise and lower the pressing rod vertically. The device has a simple structure and low cost.

[0006] To achieve the above objectives, the technical solution applied in this utility model is as follows:

[0007] A fiber optic interface component pressing device includes a frame with an upper fixed seat and a lower fixed seat. The upper fixed seat has a drive assembly and a pressing rod, which is driven to move vertically by the drive assembly. A transmission assembly and an upper tooling fixture for assembling upper metal components are fixed on the pressing rod. The lower fixed seat has a support frame and a lower tooling fixture for assembling lower metal components. The lower tooling fixture is located directly below the upper tooling fixture. The support frame has a horizontally sliding gripper assembly, which is driven to close or open by the transmission assembly to clamp or release metal components.

[0008] According to the above scheme, the driving component includes a handle, a rotating shaft, a gear, and a drive shaft. The rotating shaft is rotatably mounted on the upper fixed base, the gear is fixed on the rotating shaft, and one end of the rotating shaft is fixedly connected to the handle. Rotating the handle drives the rotating shaft and the gear to rotate. The drive shaft is vertically mounted on the upper fixed base, and a rack is provided on the drive shaft. The rack and the gear are meshed and connected, and the drive shaft is fixedly connected to the pressure rod.

[0009] According to the above scheme, the drive assembly includes a motor, a gear, and a drive shaft. The motor is mounted on the upper fixed base, the gear is fixed to the output end of the motor, the drive shaft is movably mounted on the upper fixed base, the drive shaft is provided with a rack, the rack and the gear are meshed and connected, and the drive shaft is fixedly connected to the pressure rod.

[0010] According to the above scheme, the drive assembly includes a cylinder and a drive shaft. The cylinder is mounted on the upper fixed base, and the drive shaft is mounted on the upper fixed base in a height-reducing manner. One end of the drive shaft is connected to the output end of the cylinder, and the other end of the drive shaft is fixedly connected to the pressure rod.

[0011] According to the above scheme, the upper fixed seat is vertically provided with a guide hole, the guide hole and the drive shaft are slidably connected, and the drive shaft and the pressure rod are coaxially arranged.

[0012] According to the above scheme, the support frame includes a support plate and a guide plate. The support plate is fixed on the lower fixed seat, and the guide plate is fixed on the support plate. The guide plate is provided with a sliding groove. The upper end of the lower tooling fixture is located at the center of the sliding groove. The two sets of gripper assemblies are symmetrically arranged in the sliding grooves on both sides of the lower tooling fixture. The two sets of gripper assemblies are driven to close or open by the transmission assembly.

[0013] According to the above scheme, the gripper assembly includes a slider gripper, a spring and a spring stop. The spring stop is fixed on the guide plate, the slider gripper slides in the groove, and the two ends of the spring abut against the slider gripper and the spring stop. The slider gripper is provided with a through hole one that is slidably connected to the transmission component, and the groove is provided with a through hole two that is slidably connected to the transmission component.

[0014] According to the above scheme, the transmission assembly includes a horizontal arm and two inclined arms. The horizontal arm is fixed to the pressure rod at an adjustable height by adjusting the retaining ring.

[0017] The beneficial effects of this utility model are:

[0018] This invention is designed such that, during operation, the upper metal component is placed on the upper tooling fixture, and the lower metal component is placed on the lower tooling fixture. During pressing, the pressure rod is driven to rise and fall vertically through the drive assembly, thereby pressing the upper metal component onto the lower metal component to form a metal part. At the same time, during the rising and falling process, the pressure rod drives the gripper assembly to clamp or release the metal part through the transmission assembly. Thus, a set of drive assemblies can both enable the gripper assembly to slide horizontally and enable the pressure rod to rise and fall vertically. The structure is simple and the cost is low.

[0026] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0027] Example 1:

[0028] like Figures 1 to 5As shown, the fiber optic interface component pressing device of this utility model includes a frame 20, on which an upper fixed seat 21 and a lower fixed seat 22 are provided; the upper fixed seat 21 is provided with a driving component and a pressure rod 13, the pressure rod 13 is driven to move vertically by the driving component, and a transmission component and an upper tooling fixture 12 for assembling upper metal components are fixed on the pressure rod 13; the lower fixed seat 22 is provided with a support frame and a lower tooling fixture 5 for assembling lower metal components, the lower tooling fixture 5 is located directly below the upper tooling fixture 12, and the support frame is provided with a horizontally sliding gripper assembly, the gripper assembly is driven to close or open by the transmission component, for clamping or releasing metal parts 9. With this setup, during operation, the upper metal component is placed on the upper tooling fixture 12, and the lower metal component is placed on the lower tooling fixture 5. During pressing, the pressure rod 13 is driven to rise and fall vertically through the drive assembly, thereby pressing the upper metal component onto the lower metal component to form the metal part 9. At the same time, during the rising and falling process, the pressure rod 13 drives the gripper assembly to clamp or release the metal part 9 through the transmission assembly. Thus, a set of drive assemblies can both enable the gripper assembly to slide horizontally and enable the pressure rod 13 to rise and fall vertically. The structure is simple and the cost is low.

[0029] The lower tooling fixture 5 is located directly below the upper tooling fixture 12, meaning that the lower tooling fixture 5 and the upper tooling fixture 12 are coaxially arranged to ensure the concentricity of the upper and lower metal components during pressing. The lower tooling fixture 5 is provided with holes adapted to the lower metal components, and the upper tooling fixture 12 is provided with holes adapted to the upper metal components.

[0030] Furthermore, the drive assembly includes a handle 23, a rotating shaft 24, a gear 25, and a drive shaft 26. The rotating shaft 24 is rotatably mounted on the upper fixed base 21, and the gear 25 is fixed to the rotating shaft 24. One end of the rotating shaft 24 is fixedly connected to the handle 23. Rotating the handle 23 drives the rotating shaft 24 and the gear 25 to rotate. The drive shaft 26 is vertically mounted on the upper fixed base 21. The drive shaft 26 is provided with a rack 27, which meshes with the gear 25. The drive shaft 26 is fixedly connected to the pressure rod 13. With this configuration, when controlling the lifting and lowering of the pressure rod 13, rotating the handle 23 drives the rotating shaft 24 and the gear 25 to rotate. During the rotation, the gear 25 and the rack 27 on the drive shaft 26 undergo displacement changes, thereby driving the drive shaft 26 to lift and lower the pressure rod 13.

[0031] Specifically, such as Figure 3 As shown, when gear 25 rotates clockwise, pressure rod 13 descends, and when gear 25 rotates counterclockwise, pressure rod 13 rises.

[0032] Furthermore, the upper fixed base 21 is vertically provided with a guide hole 211, which is slidably connected to the drive shaft 26. The drive shaft 26 and the pressure rod 13 are coaxially arranged. With this arrangement, under the action of the vertically arranged guide hole 211, the drive shaft 26 moves vertically up and down relative to the upper fixed base 21.

[0033] Furthermore, the support frame includes a support plate 3 and a guide plate 4. The support plate 3 is fixed to the lower fixed base 22, and the guide plate 4 is fixed to the support plate 3. The guide plate 4 is provided with a sliding groove 41. The upper end of the lower tooling fixture 5 is located at the center of the sliding groove 41. The two sets of gripper assemblies are symmetrically arranged in the sliding grooves 41 on both sides of the lower tooling fixture 5. The two sets of gripper assemblies are driven to close or open by the transmission assembly. With this configuration, the pressure rod 13 drives the transmission assembly to rise and fall synchronously during the lifting process. When the transmission assembly rises and falls, it drives the two sets of gripper assemblies to slide along the sliding groove 41 to close or open, thereby clamping or releasing the metal part 9.

[0034] Furthermore, the gripper assembly includes a slider gripper 6, a spring 7, and a spring stop 8. The spring stop 8 is fixed to the guide plate 4. The slider gripper 6 slides within the groove 41. The two ends of the spring 7 abut against the slider gripper 6 and the spring stop 8. The slider gripper 6 has a through hole 61 that slides through the transmission assembly. The groove 41 has a through hole 42 that slides through the transmission assembly. The transmission assembly includes a horizontal arm 16 and two inclined arms 15. The horizontal arm 16 is height-adjustably fixed to the pressure rod 13 via an adjusting retaining ring 14. The upper ends of the two inclined arms 15 are symmetrically fixed to the two ends of the horizontal arm 16. The lower ends of the two inclined arms 15 are symmetrically provided with outwardly bent inclined rods 151. The inclined rods 151 pass through the through hole 61 on the slider gripper 6 and the through hole 42 in the groove 41. The inner wall of the through hole 61 is formed with an inclined surface that slides through the inclined rod 151. This configuration allows for... Figure 3 and Figure 4 As shown, when the pressure rod 13 is rising, the inclined rods 151 of the two inclined arms 15 slide against the inner wall of the through hole 61, driving the two slider jaws 6 to open to both sides. When the pressure rod 13 is falling, the two slider jaws 6 are driven to close in the middle under the action of the two springs 7.

[0035] Under the action of the two springs 7, the inner walls of the through holes 61 of the two slider grippers 6 are always in contact with the inclined rods 151 of the two inclined pull arms 15. The slide groove 41 is an inverted T-shaped groove, so that the slider grippers 6 will not disengage from the slide groove 41 when sliding.

[0036] Furthermore, the upper tooling fixture 12 is fixed to the pressure rod 13 by a retaining spring 11. A coaxial sliding sleeve 10 is movably sleeved on the pressure rod 13, and a positioning ball 101 is provided on the coaxial sliding sleeve 10. The pressure rod 13 is provided with an upper annular limiting groove 132 and a lower annular limiting groove 133 at intervals, which cooperate with the positioning ball 101. This arrangement ensures that the lower tooling fixture 5 and the upper tooling fixture 12 are coaxial through the coaxial sliding sleeve 10. Specifically, in the initial state, the positioning ball 101 on the coaxial sliding sleeve 10 cooperates with the lower annular limiting groove 133 for limiting. When assembling the metal component, the coaxial sliding sleeve 10 is pushed upward until the positioning ball 101 cooperates with the upper annular limiting groove 132 for limiting. At this time, space is cleared for assembling the metal component, so that the upper metal component can be better assembled on the upper tooling fixture 12. Next, place the lower metal component on the lower tooling fixture 5. During pressing, first push the coaxial sliding sleeve 10 downward until the positioning ball 101 engages with the lower annular limiting groove 133 for limiting. At this time, the lower end of the coaxial sliding sleeve 10 is sleeved on the lower tooling fixture 5. When the pressure rod 13 descends for pressing, the pressure rod 13 will not deviate under the action of the coaxial sliding sleeve 10. During the descent of the pressure rod 13, the positioning ball 101 of the coaxial sliding sleeve 10 slides from the lower annular limiting groove 133 to the upper annular limiting groove 132.

[0037] Furthermore, a base plate 2 is fixed on the lower fixed seat 22, and a pressure sensor 1 is installed on the base plate 2. The pressure sensor 1 is correspondingly set with the lower tooling fixture 5.

[0038] The working principle of this utility model:

[0039] In the initial state, the upper tooling fixture 12 and the lower tooling fixture 5 are separated. At this time, the two inclined pull arms 15 on the pressure rod 13 drive the two slider grippers 6 to open, allowing the lower metal component to be placed on the lower tooling fixture 5. The positioning ball 101 on the coaxial sleeve 10 engages with the lower annular limiting groove 133 for limiting. Therefore, the coaxial sleeve 10 needs to be pushed upward until the positioning ball 101 engages with the upper annular limiting groove 132 for limiting. This clears space for assembling the upper metal component, allowing the upper metal component to be better assembled on the upper tooling fixture 12. After the upper metal component is assembled, the coaxial sleeve 10 is pushed downward until the positioning ball 101 engages with the lower annular limiting groove 133 for limiting. At this time, the lower end of the coaxial sleeve 10 is fitted onto the upper tooling fixture 12. On the lower fixture 5, the pressure rod 13 is driven to descend vertically by the drive assembly, thereby pressing the upper metal element onto the lower metal element to form the metal part 9. At the same time, during the descent, the pressure rod 13 is driven by the two springs 7 to drive the two slider grippers 6 to close in the middle until the metal part 9 is clamped. At this time, the upper end of the pressure rod 13 is located in the through hole 61. When the pressure rod 13 rises, the metal part 9 is clamped by the two slider grippers 6 and is dislodged from the upper fixture 12 and limited to the lower fixture 5. When the pressure rod 13 rises to the point where the inclined rod 151 slides into the through hole 61, the two slider grippers 6 release the metal part 9. After the pressure rod 13 is reset, the pressed metal part 9 can be removed from the lower fixture 5.

[0040] The stroke of the pressure rod 13 can be adjusted to adapt to the pressing of different metal parts 9, and can prevent the metal parts 9 from being damaged by pressure, thereby improving the yield of metal parts 9.

[0041] Example 2:

[0042] In this second embodiment, the drive assembly includes a motor, a gear 25, and a drive shaft 26. The motor is mounted on an upper fixed base 21, the gear 25 is fixed to the output end of the motor, and the drive shaft 26 is movably mounted on the upper fixed base 21. A rack 27 is provided on the drive shaft 26, and the rack 27 and gear 25 are meshed together. The drive shaft 26 is fixedly connected to the pressure rod 13. With this configuration, the motor drives the gear 25 to rotate in both directions, causing a change in the position of the gear 25 and rack 27, thereby driving the drive shaft 26 to raise and lower the pressure rod 13.

[0043] The difference between this second embodiment and the first embodiment lies in the structure of the driving component. The rest of the structure and principle are the same as those in the first embodiment, and will not be repeated.

[0044] Example 3;

[0045] In this third embodiment, the drive assembly includes a cylinder and a drive shaft 26. The cylinder is mounted on an upper fixed base 21, and the drive shaft 26 is vertically mounted on the upper fixed base 21. One end of the drive shaft 26 is connected to the output end of the cylinder, and the other end of the drive shaft 26 is fixedly connected to the pressure rod 13. With this configuration, the cylinder drives the drive shaft 26 to move the pressure rod 13 up and down.

[0046] The difference between this embodiment three and embodiment one is that the structure of the driving component is different. The rest of the structure and principle are the same as those in embodiment one, and will not be repeated.
