Description

Technical Field

[0001] This application relates to the field of linear guide technology, and in particular to a guide rail slider device and its processing technology. Background Technology

[0002] Linear guides are used to support and guide moving parts, enabling them to reciprocate linearly in a given direction. Based on the nature of friction, linear guides can be classified into sliding friction guides, rolling friction guides, elastic friction guides, and fluid friction guides, among others. Sliding friction guides, due to their simple structure, are more widely used in the mechanical field.

[0003] Existing linear guide mechanisms mainly consist of a guide rail and a slider. The slider is slidably mounted on the guide rail and cooperates with it. To reduce friction between the slider and the guide rail, lubricating oil is usually applied to the guide rail. However, as the slider slides between the slider and the guide rail, the lubricating oil on the guide rail is squeezed to both sides of the guide rail, resulting in a continuous reduction of the lubricating oil between the slider and the guide rail. It is difficult to apply lubricating oil manually in a timely manner, resulting in poor lubrication between the slider and the guide rail. Summary of the Invention

[0004] To address the problem of poor lubrication between the slider and the guide rail due to the difficulty of applying lubricating oil manually in a timely manner, this application provides a guide rail slider device and its processing technology.

[0005] On the one hand, the guide rail slider device provided in this application adopts the following technical solution: A guide rail slider device includes a guide rail and a slider that slides on the guide rail. The slider includes a connecting part, a sliding part, and a lateral limiting part. The guide rail is provided with a sliding groove and a lateral limiting groove. The sliding part is slidably disposed in the sliding groove to form support for the slider. The lateral limiting part is slidably disposed in the lateral limiting groove to prevent the slider from disengaging from the guide rail. The slider is provided with an oil storage cavity for storing lubricating oil. The bottom of the sliding part is provided with a wedge-shaped component, which can form a wedge-shaped space with the bottom wall of the sliding groove. The slider is provided with an oil filling channel. The oil inlet of the oil filling channel is connected to the oil storage cavity. The oil outlet of the oil filling channel is located in front of the wedge-shaped space so as to supply oil into the wedge-shaped space.

[0006] By adopting the above technical solution, the slider is first assembled onto the guide rail. At this time, the sliding part is inserted into the sliding groove, and the lateral limiting part is inserted into the lateral limiting groove. At this time, a wedge-shaped space is formed between the wedge assembly and the bottom wall of the sliding groove. Then, lubricating oil is added to the oil storage cavity. When the slider slides, the lubricating oil flows in through the large opening of the wedge-shaped space of the oil filling channel and flows out through the small opening. On the one hand, it lubricates the sliding between the slider and the bottom wall of the sliding groove. On the other hand, the lubricating oil generates an upward thrust on the slider when flowing through the wedge-shaped space, which can reduce the friction between the slider and the guide rail. This solution uses lubricating oil in the oil storage cavity to lubricate between the slider and the guide rail. Compared with the manual application method, it can improve the timeliness of lubrication and improve the lubrication effect between the slider and the guide rail.

[0007] In one specific implementation, the number of wedge components is two sets, and the large openings of the wedge spaces formed by the two sets of wedge components face opposite directions.

[0008] By adopting the above technical solution, and by setting the large openings of the two sets of wedge-shaped spaces to face opposite directions, the lubricating oil can generate an upward thrust on the slider when it slides in both directions, thereby reducing the friction between the slider and the guide rail.

[0009] In one specific implementation, the wedge assembly includes a positive portion fixedly disposed at the bottom of the sliding part. The positive portion has an inclined surface on the side facing the bottom wall of the sliding groove. The inclined surface and the bottom wall of the sliding groove form the wedge-shaped space. The large opening side of the wedge-shaped space has an oil inlet chamber communicating with the oil outlet of the refueling channel. The small opening side of the wedge-shaped space has a return oil chamber, which is connected to the refueling channel through a return oil channel.

[0010] By adopting the above technical solution, a wedge-shaped space is formed between the inclined surface and the plane of the bottom wall of the sliding groove. The lubricating oil flows in from the oil inlet chamber in front of the wedge-shaped space, and then flows into the return oil chamber through the wedge-shaped space. At this time, the pressure of the lubricating oil in the return oil chamber increases, and a part of the lubricating oil returns to the oil filling channel through the return oil channel, so as to realize the full use of the lubricating oil.

[0011] In one specific implementation, the distance from the inclined surface to the bottom wall of the sliding groove is greater than the distance from the sliding part to the bottom wall of the sliding groove.

[0012] By adopting the above technical solution, when the slider is stationary, the bottom wall of the slider and the bottom wall of the sliding groove form a support for the slider. On the one hand, this can improve the stability of the connection between the slider and the guide rail, and on the other hand, it can keep the lubricating oil in the wedge-shaped space, thereby improving the utilization rate of the lubricating oil when the slider slides.

[0013] In one specific implementation, the bottom wall of the sliding groove is lower than the lateral limiting groove and is inclined to one side. The guide rail is provided with a plurality of oil outlet holes, each of which is located on the lowest side of the sliding groove so that lubricating oil can flow out of the sliding groove. The guide rail is provided with a switch control component for controlling the opening and closing of the oil outlet holes.

[0014] By adopting the above technical solution, as the lubricating oil is used, the debris in the lubricating oil gradually increases, and it is necessary to drain the lubricating oil in the sliding groove and replace the lubricating oil. At this time, the outlet hole is opened by the switch control component, and the lubricating oil flows along the bottom wall of the sliding groove to the lowest end and is discharged from the oil outlet hole, thereby improving the convenience of lubricating oil drainage.

[0015] In one specific feasible implementation, the switch control element corresponds one-to-one with the oil outlet hole; The switch control component includes a mounting tube and a sealing rod. The mounting tube is fixedly mounted on the guide rail and communicates with the oil outlet. The mounting tube has an oil outlet strip-shaped hole. The sealing rod slides through the mounting tube and is inserted into the oil outlet to block the oil outlet. A fixing nut is threaded onto the mounting tube and is connected to the sealing rod to drive the sealing rod to insert or withdraw from the oil outlet.

[0016] By adopting the above technical solution, when controlling the oil outlet, rotating the fixing nut causes the fixing nut to drive the sealing rod to insert into the oil outlet and seal the oil outlet; rotating the fixing nut in the opposite direction causes the fixing nut to drive the sealing rod to pull out of the oil outlet and open the oil outlet, thereby realizing the control of the opening and closing of the oil outlet; by setting the oil outlet strip hole, the flow distance of the lubricating oil in the installation pipe is reduced, which facilitates the discharge of the lubricating oil.

[0017] In one specific implementation, a baffle is fixedly provided at the end of the sealing rod, and the baffle is fixedly connected to the fixing nut by a telescopic spring.

[0018] In one specific implementation, the slider is provided with a drive block, which is used to compress the telescopic spring to retract so that the sealing rod at the corresponding position of the slider can be inserted into the oil outlet hole.

[0019] By adopting the above technical solution, when replacing the lubricating oil in the sliding groove, the drive slider slides in the sliding groove to add new lubricating oil into the sliding groove. The new lubricating oil can drive the old lubricating oil to flow out from the oil outlet, thus speeding up the replacement of lubricating oil. When the slider slides to the corresponding oil outlet position, the drive block drives the sealing rod to insert into the oil outlet and seal the oil outlet, thereby ensuring the effect of the lubricating oil on the slider when flowing through the wedge-shaped space.

[0020] In one specific implementation, guide surfaces are provided at both ends of the drive block, and the sealing rod can slide onto the guide surfaces, which can guide the sealing rod to be inserted into the oil outlet hole.

[0021] By adopting the above technical solution, the drive block pushes the sealing rod into the oil outlet hole through the guide surface, thereby improving the convenience of the drive block driving the sealing rod.

[0022] On the other hand, the processing technology of the guide rail slider device provided in this application adopts the following technical solution: A manufacturing process for a guide rail slider device, using the aforementioned guide rail slider device, includes the following steps: S1. Material preparation: Prepare the raw materials for the slider and guide rail, usually aluminum alloy, steel, etc. S2. Part machining: Machining the connecting part, sliding part, lateral restraint part, oil storage cavity, oil filling channel and wedge structure on the slider; machining the corresponding sliding groove and lateral restraint groove on the guide rail; S3. Surface treatment: The guide rail and slider surface are treated, such as sandblasting, polishing, electroplating, etc. S4. Assembly: Assemble the slider onto the guide rail, and then add lubricating oil to the oil reservoir.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. When the slider slides, lubricating oil flows in through the large opening of the oil wedge-shaped space in the oil filling channel and flows out through the small opening. On the one hand, this lubricates the sliding between the slider and the bottom wall of the sliding groove. On the other hand, the lubricating oil generates an upward thrust on the slider when flowing through the wedge-shaped space, which can reduce the friction between the slider and the guide rail. This solution uses lubricating oil in the oil storage cavity to lubricate between the slider and the guide rail. Compared with the manual application method, it can improve the timeliness of lubrication and improve the lubrication effect between the slider and the guide rail. 2. As the lubricating oil is used, the debris in the lubricating oil gradually increases, and it is necessary to drain the lubricating oil from the sliding groove and replace the lubricating oil. At this time, the outlet hole is opened by the switch control component, and the lubricating oil flows along the bottom wall of the sliding groove to the lowest end and is discharged from the oil outlet hole, thereby improving the convenience of lubricating oil drainage.

[0031] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0032] This application discloses a guide rail slider device.

[0033] Reference Figure 1 , Figure 2 A guide rail slider device includes a guide rail 1 and a slider 2 that slides on the guide rail 1. The slider 2 includes a connecting part 21, a sliding part 22, and a lateral limiting part 23. There are two sets of lateral limiting parts 23, located on both sides of the connecting part 21, and the sliding part 22 is located at the bottom of the connecting part 21. The guide rail 1 is provided with a sliding groove 11 and a lateral limiting groove 12. The sliding groove 11 is located in the middle of the guide rail 1, and there are two lateral limiting grooves 12, located on both sides of the sliding groove 11 and corresponding to the lateral limiting parts 23. The sliding part 22 is slidably disposed within the sliding groove 11 to support the slider 2. Two limiting blocks 13 are provided at both ends of the sliding groove 11 on the guide rail 1. Each limiting block 13 is fixedly connected to the guide rail 1 by bolts. The two limiting blocks 13 seal both ends of the sliding groove 11, preventing the slider 2 from detaching from the guide rail 1. The lateral limiting parts 23 are slidably disposed within the lateral limiting grooves 12 to prevent the limiting blocks from detaching from the guide rail 1.

[0034] Reference Figure 1 , Figure 2The connecting part 21 is provided with an oil storage cavity 211 for storing lubricating oil. The top opening of the oil storage cavity 211 is sealed by a cover plate provided on the connecting part 21. The cover plate and the connecting part 21 are fixedly connected by screws.

[0035] Reference Figure 1 , Figure 3 The bottom of the sliding part 22 is provided with a wedge-shaped component 3, which can form a wedge-shaped space 4 between the wedge-shaped component 3 and the bottom wall of the sliding groove 11. The slider 2 is provided with a refueling channel 24, the oil inlet of the refueling channel 24 is connected to the bottom of the oil storage chamber 211, and the oil outlet of the refueling channel 24 is located in front of the wedge-shaped space 4, which can supply oil into the wedge-shaped space 4.

[0036] First, the slider 2 is assembled onto the guide rail 1. At this time, the sliding part 22 is inserted into the sliding groove 11, and the lateral limiting part 23 is inserted into the lateral limiting groove 12. At this time, a wedge-shaped space 4 is formed between the wedge-shaped component 3 and the bottom wall of the sliding groove 11. Then, lubricating oil is added to the oil storage chamber 211. When the slider 2 slides, the lubricating oil flows in along the large opening of the oil filling channel 24 into the wedge-shaped space 4 and flows out through the small opening. On the one hand, this lubricates the sliding between the slider 2 and the bottom wall of the sliding groove 11. On the other hand, the lubricating oil generates an upward thrust on the slider 2 when it flows through the wedge-shaped space 4, which can reduce the friction between the slider 2 and the guide rail 1. This solution uses the lubricating oil in the oil storage chamber 211 to lubricate between the slider 2 and the guide rail 1. Compared with the manual application method, this can improve the timeliness of lubrication and improve the lubrication effect between the slider 2 and the guide rail 1.

[0037] Reference Figure 1 , Figure 3 In this embodiment, there are two sets of wedge components 3. These two sets of wedge components 3 are arranged at the bottom of the sliding part 22 along the sliding direction of the slider 2. Each set of wedge components 3 includes a forward part 31. The forward part 31 has an inclined surface 32 on the side facing the bottom wall of the sliding groove 11. The two sets of inclined surfaces 32 have opposite inclination directions, so that the large openings of the wedge-shaped spaces 4 formed between the two sets of inclined surfaces 32 and the bottom wall of the sliding groove 11 face opposite directions. By setting the large openings of the two sets of wedge-shaped spaces 4 to face opposite directions, the lubricating oil can generate an upward thrust on the slider 2 when the slider 2 slides in both directions, thereby reducing the friction between the slider 2 and the guide rail 1. The distance from the inclined surface 32 to the bottom wall of the sliding groove 11 is greater than the distance from the sliding part 22 to the bottom wall of the sliding groove 11. This ensures that when the slider 2 is stationary, the bottom wall of the slider 2 fits against the bottom wall of the sliding groove 11, forming support for the slider 2. This improves the stability of the connection between the slider 2 and the guide rail 1, and also keeps the lubricating oil within the wedge-shaped space 4, improving the utilization rate of the lubricating oil when the slider 2 slides.

[0038] Reference Figure 1 , Figure 3The bottom of the sliding part 22 is provided with two sets of oil inlet chambers 33 and oil return chambers 34. Each wedge-shaped space 4 corresponds to one oil inlet chamber 33 and one oil return chamber 34. The oil inlet chamber 33 is located on the large opening side of the wedge-shaped space 4, and the oil return chamber 34 is located on the small opening side of the wedge-shaped space 4. The refueling channel 24 is connected to the oil inlet chamber 33, and the oil return chamber 34 is connected to the refueling channel 24 through the oil return channel 35.

[0039] Reference Figure 1 , Figure 3 A wedge-shaped space 4 is formed between the inclined surface 32 and the plane of the bottom wall of the sliding groove 11. The lubricating oil flows in from the oil inlet chamber 33 in front of the wedge-shaped space 4, and then the lubricating oil flows into the return oil chamber 34 through the wedge-shaped space 4. At this time, the pressure of the lubricating oil in the return oil chamber 34 increases, and a part of the lubricating oil returns to the oil filling channel 24 through the return oil channel 35, so as to achieve full utilization of the lubricating oil.

[0040] Reference Figure 1 , Figure 2 In this embodiment, the bottom wall of the sliding groove 11 is lower than the lateral limiting groove 12 and is inclined to one side, so that the bottom wall of the sliding groove 11 is high on one side and low on the other side. A plurality of oil outlet holes 5 are provided on the guide rail 1. The plurality of oil outlet holes 5 are spaced apart along the length direction of the guide rail 1. Each oil outlet hole 5 is located on the lowest side of the sliding groove 11, so that lubricating oil can flow out of the sliding groove 11.

[0041] Reference Figure 1 , Figure 4 and Figure 5 The guide rail 1 is equipped with a switch control element 6 for controlling the opening and closing of the oil outlet 5, and the switch control element 6 corresponds one-to-one with the oil outlet 5. In this embodiment, the switch control element 6 includes a mounting tube 61 and a sealing rod 62. The mounting tube is fixedly installed on the side wall of the guide rail 1 and is connected to the oil outlet 5.

[0042] Reference Figure 6 The bottom of the mounting pipe 61 is provided with an oil outlet strip hole 611. When the lubricating oil flows into the mounting pipe 61 from the oil outlet hole 5, it flows out from the oil outlet strip hole 611, reducing the flow distance of the lubricating oil in the mounting pipe 61 and facilitating the discharge of the lubricating oil.

[0043] Reference Figure 5 , Figure 6The sealing rod 62 slides through the mounting tube 61 and is inserted into the oil outlet 5 to block the oil outlet 5. A fixing nut 63 is threaded onto the mounting tube 61. A baffle 64 is fixed to the end of the sealing rod 62. The baffle 64 and the fixing nut 63 are fixedly connected by a telescopic spring 65. When it is necessary to block the oil outlet 5, the fixing nut 63 is rotated and moved toward the guide rail 1. The fixing nut 63 pulls the sealing rod 62 into the oil outlet 5 through the telescopic spring 65, thereby blocking the oil outlet 5. When it is necessary to open the oil outlet 5, the fixing nut 63 is rotated away from the guide rail 1. The fixing nut 63 pulls the sealing rod 62 out of the oil outlet 5 through the telescopic spring 65, thereby opening the oil outlet 5.

[0044] Reference Figure 4 The slider 2 is provided with a drive block 66, and both ends of the drive block 66 are provided with guide surfaces 67. The distance between the two guide surfaces 67 gradually increases from the side of the drive block 66 closer to the guide rail 1 to the side farther away from the guide rail 1. When the sealing rod 62 is pulled out of the oil outlet 5, the end of the sealing rod 62 is located on the sliding trajectory of the guide surface 67, thereby ensuring that the guide surface 67 guides the sealing rod 62 to be inserted into the oil outlet 5.

[0045] As the lubricating oil is used, the debris in the lubricating oil gradually increases, requiring the lubricating oil in the sliding groove 11 to be drained and replaced. At this time, by rotating the fixing nut 63 away from the guide rail 1, the fixing nut 63 pulls the sealing rod 62 out of the oil outlet 5 through the telescopic spring 65, thereby opening the oil outlet 5. The lubricating oil flows along the bottom wall of the sliding groove 11 to the lowest end and is discharged from the oil outlet 5, thereby improving the convenience of lubricating oil drainage.

[0046] When the lubricating oil in the sliding groove 11 is replaced, the drive slider 2 slides in the sliding groove 11 to add new lubricating oil into the sliding groove 11. The new lubricating oil can drive the old lubricating oil to flow out from the oil outlet 5, thus speeding up the replacement of lubricating oil. When the slider 2 slides to the position of the corresponding oil outlet 5, the drive block 66 drives the sealing rod 62 to insert into the oil outlet 5 to seal the oil outlet 5, thereby ensuring the effect of the lubricating oil on the slider 2 when it flows through the wedge-shaped space 4.

[0047] The implementation principle of the guide rail slider device in this application embodiment is as follows: First, the slider 2 is assembled onto the guide rail 1. At this time, the sliding part 22 is inserted into the sliding groove 11, and the lateral limiting part 23 is inserted into the lateral limiting groove 12. At this time, a wedge-shaped space 4 is formed between the wedge-shaped component 3 and the bottom wall of the sliding groove 11. Then, lubricating oil is added to the oil storage cavity 211. When the slider 2 slides, the lubricating oil flows in along the large opening of the oil filling channel 24 into the wedge-shaped space 4 and flows out through the small opening. On the one hand, it realizes the lubrication of the sliding between the slider 2 and the bottom wall of the sliding groove 11. On the other hand, the lubricating oil generates an upward thrust on the slider 2 when flowing through the wedge-shaped space 4, which can reduce the friction between the slider 2 and the guide rail 1. This solution uses the lubricating oil in the oil storage cavity 211 to lubricate between the slider 2 and the guide rail 1. Compared with the manual application method, it can improve the timeliness of lubrication and improve the lubrication effect between the slider 2 and the guide rail 1.

[0048] This application discloses a manufacturing process for a guide rail slider device.

[0049] A manufacturing process for a guide rail slider device, using the aforementioned guide rail slider device, includes the following steps: S1. Material Preparation: Prepare the raw materials for slider 2 and guide rail 1, typically aluminum alloy, steel, etc. Before processing, the materials need to be inspected to ensure their quality meets requirements. Simultaneously, select appropriate materials for processing based on product requirements.

[0050] S2. Part machining: The connecting part 21, sliding part 22, lateral restraint part 23, oil reservoir 211, oil filling channel 24, oil return channel 35, forward part 31, and inclined surface 32 are machined on the slider 2 through milling, turning, drilling, and cutting processes. Corresponding sliding grooves 11 and lateral restraint grooves 12 are machined on the guide rail 1. Before machining, the machine tool needs to be adjusted and inspected to ensure its accuracy and stability. During machining, it is necessary to perform machining according to the product requirements to ensure machining accuracy and surface finish.

[0051] S3. Surface treatment: The surface of the guide rail and slider 2 is treated, such as by sandblasting, polishing, or electroplating. Surface treatment can improve the surface finish and corrosion resistance of the product, and also enhance its appearance.

[0052] S4. Assembly: Assemble the slider 2 onto the guide rail 1, then add lubricating oil into the oil storage chamber 211, then install the two limit blocks 13 at both ends of the sliding groove 11 with bolts, and then install the cover plate at the opening of the oil storage chamber 211 to seal the opening of the oil storage chamber 211.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
