Description

Technical Field

[0001] This utility model relates to the field of motion slider technology, specifically to a motion slider oil-filling structure. Background Technology

[0002] The slider is an important component of mechanical transmission and is widely used in conjunction with the guide rail. It is a mold assembly that can slide perpendicular to the mold opening and closing direction or at a certain angle to the mold opening and closing direction during the mold opening action.

[0003] Most existing motion slider oil filling structures fill oil by opening oil passages inside the housing. Traditional oil passages often use tortuous paths, which can easily lead to lubricating oil overflowing, being wasted, or becoming blocked. It is also difficult for lubricating oil to accurately reach the interface between the inner return unit and the ball track through complex oil passages, creating lubrication blind spots, making it easy to get clogged and difficult to repair. Moreover, most sliders rely on the rolling of the rollers themselves to distribute the lubricating oil (drip lubrication), resulting in uneven oil film coverage. Insufficient lubrication on the roller surface can exacerbate friction, especially under high-speed or heavy-load conditions, which can easily lead to abnormal wear or temperature rise. Utility Model Content

[0004] The purpose of this invention is to provide a motion slider oil-filling structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sliding block oil-filling structure, comprising a sliding block housing, four roller shafts rotatably connected inside the sliding block housing, the bottom ends of the four roller shafts extending out of the sliding block housing, and movable rollers provided at the extended ends of the four roller shafts. A first toothed ring is provided on the outer surface of the roller shafts inside the sliding block housing, a second toothed ring is meshed with one side of the first toothed ring, an interface tube is provided at the middle position of the second toothed ring, the bottom of the interface tube extends out of the sliding block housing, an oil storage cavity is provided at the extended end of the interface tube, a rubber positioning element is provided on the outer surface of the oil storage cavity, an opening is provided on one side of the oil storage cavity facing the movable roller, an oil filling hole is provided on one side of the movable roller, and insertion pipes are inserted into the top ends of the four interface tubes. Two insertion pipes form a group, and a horizontal plate is provided at the top end of each group of insertion pipes. The top ends of the two horizontal plates are connected to an oil delivery pipe.

[0006] Preferably, both ends of the slider housing are provided with dustproof ends, and a top cover is detachably installed on the top of the slider housing. Fixing holes are provided at the four corners of the top cover. The dustproof ends protect both ends of the slider, thus protecting the inherent structure of the moving slider. Threaded holes corresponding to the fixing holes are provided at the four corners of the top of the slider housing. When installing the top cover, bolts are installed at the fixing holes and fixed in the threaded holes to secure the top cover.

[0007] Preferably, a top cover extends from the top of the oil pipe, and a through hole is provided at the middle of the top of the top cover. The through hole extends from the top of the oil pipe, and a plug is installed at the extended end of the oil pipe. When adding lubricating oil, the plug is pulled out, lubricating oil is injected into the top of the oil pipe, and after injection, the plug is installed on the top of the oil pipe to prevent lubricating oil leakage.

[0008] Preferably, the inner wall of the slider housing is provided with two fixing plates, and two locking holes are provided at the top two ends of the two horizontal plates. The two horizontal plates are connected to the top of the two fixing plates. The top of the two fixing plates is provided with threaded holes corresponding to the locking holes. The horizontal plates are fixed to the top of the horizontal plates by screws, so that the horizontal plates are fixed in a preset position.

[0009] Preferably, the insertion tube matches the interface tube, and a sealing ring is provided on the outer surface of the insertion tube. When the horizontal plate is fixed to the top of the fixing plate, the insertion tube is inserted into the corresponding interface tube. The sealing ring reduces the gap between the insertion tube and the interface tube, preventing lubricating oil leakage.

[0010] Preferably, the rubber positioning element matches the oil storage cavity, and the rubber positioning element is fixedly installed inside the slider housing. The rubber positioning element limits the oil storage cavity, allowing the oil storage cavity to rotate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The oil-filling structure of this moving slider drives the oil storage chamber to rotate synchronously through the meshing of the first and second toothed rings as the moving roller rotates. Each time the oil storage chamber rotates once, its oil filling hole aligns with the opening of the rubber positioning part only once, thereby releasing a fixed amount of lubricating oil onto the moving roller. This ensures the uniformity and accuracy of the lubricating oil supply and effectively avoids the problems of too much or too little oil that may be caused by traditional manual or continuous oil supply methods.

[0013] 2. The oil-filling structure of this motion slider connects the oil supply lines of four lubrication points to a single unified oil delivery pipe via a connector. The horizontal plate, oil delivery pipe, and connector form an independent module that can be easily disassembled from the slider housing. This simplifies the cleaning, unblocking, and maintenance of the oil circuit, eliminating the need for complex disassembly of the slider body and significantly reducing maintenance costs and time.

[0022] like Figures 1 to 5As shown, the oil-filled sliding block structure of this embodiment includes a sliding block housing 1. The sliding block housing 1 has an integrated drive structure to drive the sliding block. Four roller shafts 4 are rotatably connected inside the sliding block housing 1. The bottom ends of the four roller shafts 4 extend out of the sliding block housing 1, and each extension end of the four roller shafts 4 is equipped with a movable roller 14. Two movable rollers 14 on the same side form a group, and the two groups of movable rollers 14 are located on both sides of the guide rail, limiting the movement of the sliding block housing 1. The outer surface of the roller shafts 4 inside the sliding block housing 1... A first toothed ring 13 is provided on the surface. The moving roller 14 needs to rotate to reduce the friction between it and the guide rail, which affects the movement of the slider. A second toothed ring 15 is meshed with one side of the first toothed ring 13. When the moving roller 14 rotates, it will rotate the first toothed ring 13, causing the second toothed ring 15 to rotate. An interface pipe 17 is provided at the middle position of the second toothed ring 15. The bottom of the interface pipe 17 extends out of the slider housing 1. An oil storage cavity 18 is provided at the extended end of the interface pipe 17. The interface pipe 17 can deliver lubricating oil to the storage cavity. The oil reservoir 18 stores oil. When the second gear ring 15 rotates, the oil reservoir 18 rotates synchronously. A rubber positioning element 16 is provided on the outer surface of the oil reservoir 18. One side of the rubber positioning element 16 has an opening facing the moving roller 14, and one side of the oil reservoir 18 has an oil filling hole 19. The rubber positioning element 16 matches the oil reservoir 18. When the oil reservoir 18 rotates, causing the oil filling hole 19 to be positioned at the opening of the rubber positioning element 16, lubricating oil will be discharged from the oil filling hole 19. The lubricating oil discharge and the moving roller 14 are synchronized. The roller 14 contacts, and lubricating oil is loaded on the outer surface of the moving roller 14 to reduce the friction between the moving roller 14 and the guide rail. The top of each of the four interface pipes 17 is connected to a connector 10. Two connectors 10 form a group, and the top of each group of connectors 10 is provided with a horizontal plate 6. The tops of the two horizontal plates 6 are connected to an oil supply pipe 9. The horizontal plate 6 is detachably installed inside the slider housing 1, so that lubricating oil can be delivered without making holes inside the slider housing 1, which facilitates the clearing of the oil supply path and does not require disassembly of the slider housing 1.

[0023] Specifically, dustproof ends 2 are provided at both ends of the slider housing 1, and a top cover 3 is detachably installed on the top of the slider housing 1. Fixing holes 8 are provided at the four corners of the top cover 3. The dustproof ends 2 protect the two ends of the slider and protect the inherent structure of the moving slider. Threaded holes corresponding to the fixing holes 8 are provided at the four corners of the top of the slider housing 1. When installing the top cover 3, bolts are installed at the fixing holes 8 and fixed in the threaded holes to secure the top cover 3.

[0024] Furthermore, a top cover 3 extends from the top of the oil pipe 9, and a through hole 7 is provided at the middle of the top of the top of the top cover 3. The through hole 7 extends from the top of the oil pipe 9, and a plug 11 is installed at the extended end of the oil pipe 9. When adding lubricating oil, the plug 11 is pulled out, and lubricating oil is injected into the top of the oil pipe 9. After injection, the plug 11 is installed on the top of the oil pipe 9 to prevent lubricating oil leakage.

[0025] Furthermore, the inner wall of the slider housing 1 is provided with two fixing plates 5, and two locking holes 12 are provided at the top two ends of the two horizontal plates 6. The two horizontal plates 6 are connected to the top of the two fixing plates 5. The top of the two fixing plates 5 is provided with threaded holes corresponding to the locking holes 12. The horizontal plates 6 are fixed to the top of the horizontal plates 6 by screws, so that the horizontal plates 6 are fixed in the preset position.

[0026] Furthermore, the insertion tube 10 is matched with the interface tube 17. A sealing ring is provided on the outer surface of the insertion tube 10. When the horizontal plate 6 is fixed to the top of the fixing plate 5, the insertion tube 10 is inserted into the corresponding interface tube 17. The sealing ring reduces the gap between the insertion tube 10 and the interface tube 17 to prevent lubricating oil leakage.

[0027] Furthermore, the rubber positioning component 16 is matched with the oil storage cavity 18. The rubber positioning component 16 is fixedly installed inside the slider housing 1. The rubber positioning component 16 limits the oil storage cavity 18, allowing the oil storage cavity 18 to rotate.

[0028] The usage method of this embodiment is as follows: After the motion slider is installed outside the guide rail, open the plug 11 at the top of the oil supply pipe 9 on the top cover 3 of the slider. Use an oiling tool to add lubricating oil into the system through the oil supply pipe 9. The lubricating oil will flow through the oil supply pipe 9-plug pipe 10-interface pipe 17 and finally flow into and be stored in the four oil storage chambers 18. After the filling is completed, tighten the plug 11 to prevent dust from entering and lubricating oil from leaking. Start the equipment and let the motion slider move back and forth normally on the guide rail. The movement of the slider will drive the moving roller 14 to rotate, which in turn drives the oil storage chambers 18 to rotate through the first toothed ring 13 and the second toothed ring 15. Each oil storage chamber 18 rotates once. The oil filling hole 19 on the top will align with the opening of the rubber positioning part 16 once, releasing a fixed amount of lubricating oil, which will drip precisely onto the corresponding moving roller 14. The lubricating oil will spread evenly on the moving roller 14, thereby achieving uniform lubrication of the guide rail. If it is necessary to clean or unclog the oil passage, the bolts fixing the top cover 3 can be unscrewed, the top cover 3 can be opened, and the screws connecting the horizontal plate 6 and the fixing plate 5 can be unscrewed. The entire integrated oil supply module (including the horizontal plate 6, oil supply pipe 9, and plug pipe 10) can then be taken out upwards for maintenance. After maintenance, the module can be reinstalled, ensuring that the plug pipe 10 is accurately inserted into the interface pipe 17. Finally, the top cover 3 can be reinstalled and tightened.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
