Description
Technical Field
[0001] This utility model relates to the field of slide rail assembly technology, specifically to an outer rail lubrication device. Background Technology
[0002] Hardware slide rail assemblies typically consist of inner and outer guide rails, balls, cages, and other components. During the slide rail assembly process, the outer guide rail, as a key component for force bearing and guidance, needs to be evenly coated with lubricating oil along its ball grooves and contact surfaces. The amount of lubricating oil should be enough to cover the surface with a thin layer to ensure smooth sliding and provide protection for the long-term use of the assembly.
[0003] In existing technologies, the oil outlet of external rail lubrication devices is mostly simple in structure and lacks an effective closed protection design. After accurately lubricating the inner side of the external guide rail, the oil outlet needs to move and extend into the next set of external guide rails for operation, during which the oil outlet remains open. Due to the fluidity of the lubricating oil, the oil outlet is prone to dripping, which not only wastes lubricating oil but also contaminates the equipment worktable and non-lubricated areas of the external guide rail, potentially affecting the assembly accuracy of the slide rail and increasing subsequent cleaning and maintenance costs. Therefore, to address the above technical problems, an external rail lubrication device is proposed. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model proposes an external rail lubrication device. After lubrication of the external guide rails is completed, the oil outlet can be easily covered to prevent the oil nozzle from dripping before it moves and extends into the next set of external guide rails. This avoids wasting lubricating oil, affecting the assembly accuracy of the guide rails, and increasing subsequent cleaning and maintenance costs.
[0005] An external rail refueling device includes: frame; The mounting plate is connected to the frame via a moving mechanism, which drives the mounting plate to move along the length and height of the frame. Two sets of oil outlet nozzles are arranged opposite each other. The two sets of oil outlet nozzles are connected to the mounting plate via an adjustment mechanism. The adjustment mechanism drives the two sets of oil outlet nozzles to move closer or further apart. Each set of oil outlet nozzles has an oil outlet on its opposite side at the bottom. The sealing assembly includes a baffle and a transmission assembly. The baffle is rotatably mounted on both sets of oil outlets. The transmission assembly is mounted on the two sets of oil outlets and connected to the two sets of baffles. It is used to drive the two sets of baffles to block or open the oil outlet when the two sets of oil outlets are relatively close or far apart.
[0006] The beneficial effects of the above-mentioned external rail refueling device are as follows: When the outer guide rail is below the oil outlet, the mounting plate is driven downward by the moving mechanism to extend the oil outlet into the outer guide rail. Then, the two sets of oil outlets are driven to move away from each other by the adjusting mechanism. This movement of the two sets of oil outlets drives the two sets of baffles to rotate and open the oil outlet, bringing it closer to the oiling area on the outer guide rail. At this time, the mounting plate is driven to move along the length of the frame by the moving mechanism to lubricate along the length of the outer guide rail. After lubrication, the two sets of oil outlets are driven to move closer to each other by the adjusting mechanism. This movement of the two sets of oil outlets drives the two sets of baffles to rotate in opposite directions by the transmission component to block the oil outlet. Finally, the mounting plate is driven upward by the moving mechanism to remove the oil outlet from the current outer guide rail. The above operation is repeated when the next set of outer guide rails is below the oil outlet. This method facilitates blocking the oil outlet after lubrication of the outer guide rails, preventing leakage before the oil outlet moves and extends into the next set of outer guide rails. This avoids wasting lubricating oil, affecting the assembly accuracy of the slide rail, and increasing subsequent cleaning and maintenance costs.
[0007] In one embodiment, the transmission assembly includes gears, racks, and springs; the gears are coaxially arranged at both ends of the baffle, and racks that mesh with the gears are slidably arranged on both sides of the two sets of oil outlets. One end of the two sets of racks on the same oil outlet is connected to an abutment plate, and the two sets of abutment plates can abut or separate. Springs are respectively arranged between the two sets of abutment plates and the two sets of oil outlets, and the springs are used to provide a thrust for the two sets of abutment plates to move closer to each other.
[0008] In one embodiment, both sets of abutment plates are provided with guide posts parallel to the rack, one end of the guide post is slidably inserted into the oil outlet, the spring is sleeved on the guide post, and both ends abut against the oil outlet and the abutment plate respectively.
[0009] In one embodiment, both sets of oil nozzles are provided with a receiving groove, and the two sets of baffles can rotate into the receiving groove after opening the oil outlet.
[0010] In one embodiment, the moving mechanism includes a lateral moving component and a vertical moving component. The lateral moving component includes a sliding seat, a track, and a driving component. The track is disposed on the frame, and the sliding seat is slidably fitted onto the track along the length direction of the frame. The driving component is disposed on the frame and connected to the sliding seat to drive the sliding seat to move. The mounting plate is connected to the sliding seat through the vertical moving component, and the vertical moving component is used to drive the mounting plate to move along the height direction of the frame.

[0018] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0019] Please see Figures 1 to 3 An external rail refueling device according to one embodiment includes a frame 10, a mounting plate 20, oil nozzles 30, and a sealing assembly. The mounting plate 20 is connected to the frame 10 via a moving mechanism, which drives the mounting plate 20 to move along the length and height of the frame 10. Two sets of oil nozzles 30 are arranged opposite each other, and the two sets of oil nozzles 30 are connected to the mounting plate 20 via an adjusting mechanism. The adjusting mechanism drives the two sets of oil nozzles 30 to move closer or further apart relative to each other. Each set of oil nozzles 30 has an oil outlet 301 on its opposite side at the bottom. The sealing assembly includes a baffle 40 and a transmission assembly. The baffle 40 is rotatably mounted on each set of oil nozzles 30. The transmission assembly is mounted on the two sets of oil nozzles 30 and connected to the two sets of baffles 40, used to drive the two sets of baffles 40 to block or open the oil outlets 301 when the two sets of oil nozzles 30 move closer or further apart relative to each other.
[0020] In the above embodiment, when the outer guide rail is below the oil outlet 30, the mounting plate 20 is driven downward by the moving mechanism to extend the oil outlet 30 into the outer guide rail. Then, the two sets of oil outlets 30 are driven to move away from each other by the adjusting mechanism. The relative movement of the two sets of oil outlets 30 can drive the two sets of baffles 40 to rotate and open the oil outlet 301 through the transmission component, and bring the oil outlet 301 closer to the oiling part of the outer guide rail. At this time, the mounting plate 20 is driven to move along the length of the frame 10 by the moving mechanism to perform oiling along the length of the outer guide rail. After the oiling is completed, the adjusting mechanism drives the two sets of oil outlets 30 to move downward by the moving mechanism to extend the oil outlet 30 into the outer guide rail. When the two sets of oil outlets 30 move relatively close to each other, the transmission component drives the two sets of baffles 40 to rotate in opposite directions to block the oil outlet 301. Finally, the moving mechanism drives the mounting plate 20 to move upward, which will cause the oil outlet 30 to exit the current outer guide rail. After the next set of outer guide rails is below the oil outlet 30, the above operation can be repeated. After the outer guide rails are lubricated, it is easy to block the oil outlet 301, so as to avoid the oil outlet 30 from dripping before it moves and extends into the next set of outer guide rails, thereby avoiding the waste of lubricating oil, affecting the assembly accuracy of the slide rail, and increasing the subsequent cleaning and maintenance costs.
[0021] Please see Figure 3 In one embodiment, the transmission assembly includes a gear 401, a rack 402, and a spring 403. Gears 401 are coaxially arranged at both ends of the baffle 40. Racks 402 that mesh with gears 401 are slidably arranged on both sides of the two sets of oil outlets 30. One end of the two sets of racks 402 on the same oil outlet 30 is connected to an abutment plate 404. The two sets of abutment plates 404 can abut or separate. Springs 403 are respectively arranged between the two sets of abutment plates 404 and the two sets of oil outlets 30. The springs 403 are used to provide a thrust for the two sets of abutment plates 404 to move closer to each other.
[0022] In the above embodiment, when the two sets of oil nozzles 30 move away from each other, the spring 403 pushes the two sets of abutment plates 404 to move closer to each other. The two sets of abutment plates 404 move backward relative to each other, driving the rack 402 to move. The rack 402 moves and meshes with the gear 401, which drives the two sets of baffles 40 to rotate and open the oil outlet 301. When the two sets of oil nozzles 30 move closer to each other, the two sets of abutment plates 404 abut against each other, driving the rack 402 to move in the opposite direction. At this time, the spring 403 is compressed and contracts. The rack 402 moves in the opposite direction and meshes with the gear 401, which drives the two sets of baffles 40 to rotate in the opposite direction and block the oil outlet 301. This makes it convenient to drive the two sets of baffles 40 to block or open the oil outlet 301 when the two sets of oil nozzles 30 are closer or farther apart.
[0023] Specifically, in the above embodiment, both sides of the two sets of oil outlet nozzles 30 are provided with fixing frames 303, and the rack 402 slides through the fixing frames 303 to ensure the stability of the rack 402 sliding.
[0024] Based on the above embodiment, further, each of the two sets of abutment plates 404 is provided with a guide post 405 parallel to the rack 402. One end of the guide post 405 slides through the oil outlet 30, and the spring 403 is sleeved on the guide post 405, with both ends abutting against the oil outlet 30 and the abutment plate 404 respectively. By providing the guide post 405 to guide the extension and retraction of the spring 403, the service life of the spring 403 can be improved.
[0025] Based on the above embodiment, further, both sets of oil outlets 30 are provided with receiving grooves 302, and the two sets of baffles 40 can rotate into the receiving grooves 302 after opening the oil outlets 301. This can prevent the baffles 40 from interfering with the outer guide rail when the oil outlets 30 move relatively far apart.
[0026] Please see Figure 1 , Figure 4 and Figure 5 In one embodiment, the moving mechanism includes a lateral moving component and a vertical moving component. The lateral moving component includes a sliding seat 50, a track 501, and a driving component. The track 501 is disposed on the frame 10. The sliding seat 50 is slidably sleeved on the track 501 along the length direction of the frame 10. The driving component is disposed on the frame 10 and connected to the sliding seat 50 to drive the sliding seat 50 to move. The mounting plate 20 is connected to the sliding seat 50 through the vertical moving component, which drives the mounting plate 20 to move along the height direction of the frame 10.
[0027] Specifically, the drive assembly includes a toothed pulley 502, a toothed belt 503, and a motor 504; the frame 10 is rotatably equipped with toothed pulleys 502 at both ends, and the two sets of toothed pulleys 502 are connected by a toothed belt 503; the motor 504 is mounted on the frame 10, and its output shaft is coaxially connected to one of the sets of toothed pulleys 502; the sliding seat 50 is equipped with a clamping seat 505, and the clamping seat 505 is connected to the toothed belt 503.
[0028] In the above embodiment, the toothed belt 503 can be moved by the toothed pulley 502 driven by the motor 504. The movement of the toothed belt 503 can drive the sliding seat 50 to move through the clamping seat 505. Thus, the mounting plate 20 can be moved along the length of the frame 10 through the sliding seat 50 and the vertical moving component. The stability of the sliding seat 50 is ensured by the cooperation between the track 501 and the sliding seat 50.
[0029] Please refer to the following: Figure 6 Specifically, the vertical movement component includes a telescopic cylinder 506; the telescopic cylinder 506 is vertically mounted on the sliding seat 50, and its bottom telescopic end is connected to the mounting plate 20. By driving the telescopic cylinder 506 to extend or retract, the mounting plate 20 can be moved along the height direction of the frame 10.
[0030] Furthermore, the vertical movement assembly also includes guide rods 507; both ends of the sliding seat 50 are provided with sliding sleeves 508, and guide rods 507 that slide along the height direction of the frame 10 are inserted into the sliding sleeves 508 at both ends, and the bottom ends of both sets of guide rods 507 are connected to the mounting plate 20. This ensures the stability of the mounting plate 20 as it moves along the height direction of the frame 10.
[0031] Please see Figure 1 and Figure 2 In one embodiment, the adjusting mechanism includes a pneumatic gripper 60; the pneumatic gripper 60 is disposed at the bottom end of the mounting plate 20, and two sets of oil outlet nozzles 30 are respectively disposed on the two sets of clamping claws 601 of the pneumatic gripper 60. By driving the two sets of clamping claws 601 of the pneumatic gripper 60 to move closer or further apart, the two sets of oil outlet nozzles 30 can be moved closer or further apart. It is understood that the pneumatic gripper 60 is prior art, and its working principle will not be described in detail.
[0032] The specific implementation method of the above-mentioned outer rail refueling device is as follows: When the outer guide rail is below the oil outlet 30, the extension cylinder 506 drives the mounting plate 20 to move downwards, causing the oil outlet 30 to extend into the outer guide rail. Then, the two sets of clamping claws 601 of the pneumatic gripper 60 move away from each other, causing the two sets of oil outlets 30 to move away from each other. At this time, the spring 403 pushes the two sets of abutment plates 404 to move closer to each other. The two sets of abutment plates 404 move backwards, causing the rack 402 to move. The rack 402 moves and meshes with the gear 401, which drives the two sets of baffles 40 to rotate, opening the oil outlet 301 and bringing the oil outlet 301 closer to the oiling part of the outer guide rail. Then, the motor 504 drives the toothed pulley 502 to rotate, driving the toothed belt 503 to move. The movement of the toothed belt 503 drives the sliding seat 50 to move through the clamping seat 505, thereby causing the oil outlet 30 to move along the length of the frame 10 and to oil the oil along the length of the outer guide rail.
[0033] After refueling, the two sets of gripping claws 601 of the pneumatic gripper 60 move closer to each other, causing the two sets of oil outlets 30 to move closer to each other. At this time, the two sets of abutting plates 404 abut against each other, driving the rack 402 to move in the opposite direction, and causing the spring 403 to be compressed and contracted. The rack 402 moves in the opposite direction and meshes with the gear 401, which drives the two sets of baffles 40 to rotate in the opposite direction to block the oil outlet 301. Finally, the extension cylinder 506 is driven to retract, driving the mounting plate 20 to move upward and causing the oil outlet 30 to exit the current outer guide rail. After the next set of outer guide rails is below the oil outlet 30, the above operation can be repeated. After refueling the outer guide rails, it is easy to block the oil outlet 301, avoiding the oil outlet 30 from dripping before it moves and extends into the next set of outer guide rails, thereby avoiding the waste of lubricating oil, affecting the assembly accuracy of the slide rail, and increasing the subsequent cleaning and maintenance costs.
