Description

Technical Field

[0001] This utility model relates to the field of optical fiber fusion splicing-transmission components, specifically to a cam propulsion mechanism for a hollow optical fiber fusion splicer. Background Technology

[0002] During fiber optic fusion splicing, the welding unit needs to be advanced and reset. Existing fiber optic fusion splicing mechanisms achieve uniform advancement through various methods to ensure welding quality. However, regardless of the advancement method used, it is generally driven by a motor. If the advancement method requires it, a motor with corresponding functions is also needed. For example, if a cam or lead screw method is used for advancement, the motor may need to rotate bidirectionally. If a gear set is used for advancement, the clutch of the gear set replaces the direction of the motor, but it is necessary to convert the rotation of the gears into linear motion through a straight-guide component.

[0003] In existing cam propulsion devices, the cam is frequently in contact with the propulsion section during operation, which easily leads to cam wear. After the cam wears, it will cause vibration of the propulsion mechanism, resulting in unstable operation of the propulsion mechanism and affecting the quality of optical fiber fusion splicing. Therefore, a cam propulsion mechanism for hollow optical fiber fusion splicers is proposed. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a cam propulsion mechanism for a hollow fiber fusion splicer.

[0005] The technical solution adopted by this utility model to solve its technical problem is a cam propulsion mechanism for a hollow fiber fusion splicer, including a mounting platform. A second gear is rotatably mounted on the top of the mounting platform. A cam is fixedly connected to the center of the top of the second gear. A first fixing plate is fixedly mounted on the top of the mounting platform. A guide rod is installed through the interior of the first fixing plate. One end of the guide rod is fixedly connected to one side of a connecting block. A mounting seat is fixedly connected to the other side of the connecting block. A mounting groove is opened on the side of the mounting seat away from the connecting block. The mounting groove is used for the insertion of a lubricating block.

[0006] A first spring is sleeved on the outer side of the guide rod. One end of the first spring is fixedly connected to one side of the connecting block, and the other end of the first spring is fixedly connected to one side of the first fixing plate. The end of the guide rod away from the connecting block is fixedly connected to one side of the limiting plate. The limiting plate is located on the side of the first fixing plate away from the connecting block.

[0007] By adopting the above technical solution, the surface of the cam is covered with a layer of lubricating medium by the lubricating block for each rotation. This medium is consumed when it comes into contact with the pulley in the subsequent propulsion section. This not only avoids direct hard friction between the cam and the pulley, but also delays the wear of the cam body by sacrificing the lubricating layer, thus significantly extending its service life.

[0008] Specifically, a motor housing is fixedly installed at the bottom of the mounting platform, and a motor is fixedly installed inside the motor housing.

[0009] Specifically, the output end of the motor passes through the mounting platform and is fixedly connected to the bottom center of the first gear. The first gear is rotatably mounted on the top of the mounting platform and meshes with the second gear.

[0010] Specifically, a fan is installed inside the motor housing, with an air inlet on the side of the motor housing closest to the fan and an air outlet on the side of the motor housing furthest from the fan.

[0011] By adopting the above technical solution, the starting motor drives the first gear to rotate, and the power is transmitted to the second gear through gear meshing, thereby driving the cam to rotate synchronously. The fan in the motor box draws in external air through the air inlet, and after being cooled by the motor, it is discharged from the air outlet, effectively reducing the operating temperature of the motor and ensuring the continuous and stable operation of the equipment.

[0012] Specifically, the cam is adapted to the propulsion section, and one end of the propulsion section is provided with a pulley, which contacts the side of the cam.

[0013] Specifically, the end of the propulsion section away from the pulley is fixedly connected to one end of the push rod, the push rod passes through the interior of the second fixed plate, and a second spring is sleeved on the outside of the push rod. One end of the second spring is fixedly connected to one side of the second fixed plate, and the other end of the second spring is fixedly connected to one side of the propulsion section.

[0014] By adopting the above technical solution, during the rotation of the cam, its convex profile pushes the pulley and the propulsion section to move towards the push rod, compressing the second spring; when the cam rotates to the lowest position, the second spring rebounds and pushes the propulsion section to reset, forming a periodic reciprocating motion. The lubricating layer formed on the cam surface by the lubricating block in advance can reduce the frictional loss between the pulley and the cam.

[0015] The beneficial effects of this utility model are:

[0016] (1) The cam propulsion mechanism for a hollow fiber fusion splicer described in this utility model has a lubricating medium covering its surface with a lubricating block for each rotation of the cam. This medium is consumed when it comes into contact with the pulley of the propulsion section. This not only avoids direct hard friction between the cam and the pulley, but also delays the wear of the cam body by sacrificing the lubricating layer, thus significantly extending its service life.

[0017] (2) The cam propulsion mechanism for a hollow fiber fusion splicer described in this utility model starts the motor to drive the first gear to rotate, and transmits power to the second gear through gear meshing, thereby driving the cam to rotate synchronously. The fan in the motor box draws in external air through the air inlet, and after being cooled by the motor, it is discharged from the air outlet, effectively reducing the operating temperature of the motor and ensuring the continuous and stable operation of the equipment.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] As one embodiment of this utility model, such as Figures 1-3 As shown, the cam propulsion mechanism for a hollow fiber fusion splicer of this utility model includes a mounting platform 8. A second gear 10 is rotatably mounted on the top of the mounting platform 8. A cam 16 is fixedly connected to the center of the top of the second gear 10. A first fixing plate 7 is fixedly mounted on the top of the mounting platform 8. A guide rod 4 is installed through the interior of the first fixing plate 7. One end of the guide rod 4 is fixedly connected to one side of a connecting block 3. A mounting seat 2 is fixedly connected to the other side of the connecting block 3. A mounting groove 22 is provided on the side of the mounting seat 2 away from the connecting block 3. The mounting groove 22 is used for the insertion of a lubricating block 9.

[0025] A first spring 6 is sleeved on the outside of the guide rod 4. One end of the first spring 6 is fixedly connected to one side of the connecting block 3, and the other end of the first spring 6 is fixedly connected to one side of the first fixing plate 7. The end of the guide rod 4 away from the connecting block 3 is fixedly connected to one side of the limiting plate 5. The limiting plate 5 is located on the side of the first fixing plate 7 away from the connecting block 3.

[0026] When in use, when the protruding part of the cam 16 contacts the lubricating block 9, it will push the mounting base 2 to slide along the guide rod 4 toward the first fixed plate 7. At this time, the first spring 6 is compressed and stores energy. When the non-protruding surface of the cam 16 rotates to the position of the lubricating block 9, the first spring 6 releases its elastic force to push the mounting base 2 to reset, so as to realize the cyclic lubrication protection of the cam 16 by the lubricating block 9.

[0027] It should be noted that the height of the mounting base 2 is higher than that of the second gear 10 and is parallel to the cam 16. The specific material of the lubricating block 9 is PTFE and epoxy resin with moderate hardness, such as Klüberfix Paste L2. After the lubricating block 9 is consumed after a period of use, the lubricating block 9 can be removed from the mounting slot 22 and a new lubricating block 9 can be inserted for the cam to use.

[0028] This utility model also includes a motor housing 19 fixedly installed at the bottom of the mounting platform 8, and a motor 20 fixedly installed inside the motor housing 19.

[0029] The present invention further includes that the output end of the motor 20 passes through the mounting platform 8 and is fixedly connected to the bottom center of the first gear 1, the first gear 1 is rotatably mounted on the top of the mounting platform 8, and the first gear 1 is meshed with the second gear 10.

[0030] The present invention also includes a fan 18 installed inside the motor housing 19, an air inlet 17 on the side of the motor housing 19 near the fan 18, and an air outlet 21 on the side of the motor housing 19 away from the fan 18.

[0031] When in use, the starter motor 20 drives the first gear 1 to rotate, and the power is transmitted to the second gear 10 through gear meshing, thereby driving the cam 16 to rotate synchronously. The fan 18 in the motor housing 19 draws in external air through the air inlet 17, and after being cooled by the motor 20, it is discharged from the air outlet 21, which effectively reduces the operating temperature of the motor and ensures the continuous and stable operation of the equipment.

[0032] The present invention also includes that the cam 16 is adapted to the propulsion section 12, and one end of the propulsion section 12 is provided with a pulley 11, the pulley 11 being in contact with the side of the cam 16.

[0033] The present invention further includes that one end of the propulsion section 12 away from the pulley 11 is fixedly connected to one end of the push rod 15, the push rod 15 passes through the interior of the second fixed plate 14, and a second spring 13 is sleeved on the outside of the push rod 15. One end of the second spring 13 is fixedly connected to one side of the second fixed plate 14, and the other end of the second spring 13 is fixedly connected to one side of the propulsion section 12.

[0034] During use, as the cam 16 rotates, its raised profile pushes the pulley 11 and the push section 12 toward the push rod 15, compressing the second spring 13. When the cam 16 rotates to the lowest position, the second spring 13 rebounds and pushes the push section 12 back to its original position, forming a periodic reciprocating motion. The lubricating layer formed on the surface of the cam 16 by the lubricating block 9 can reduce the frictional loss between the pulley 11 and the cam 16.

[0035] It should be noted that the second fixing plate 14 is not suspended, but is fixedly connected to other parts of the fiber optic fusion splicer (not shown in the figure) to provide support for the push rod 15.

[0036] In use, the present invention starts the motor 20 by connecting an external power source. When the motor 20 starts and drives the first gear 1 to rotate, the first gear 1 drives the second gear 10 to rotate. The rotation of the second gear 10 drives the cam 16 to rotate. During the rotation of the cam 16, the protruding outer surface of the cam 16 contacts the outer surface of the lubricating block 9 and pushes the mounting base 2 towards the first fixed plate 7, thereby compressing the first spring 6. When the non-protruding surface of the cam 16 rotates to the position of the lubricating block 9, the first spring 6 pushes the mounting base 2 and the lubricating block 9 to reset, facilitating the lubrication of the protruding surface of the cam 16 next time. The lubricating block 9, in conjunction with the rotation of the cam 16, applies a lubricating layer to the protruding surface of the cam 16. This lubricating layer is consumed during the contact between the cam 16 and the subsequent propulsion section 12, thus protecting the cam 16, extending its service life, and reducing its wear rate.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
