Technical Field

[0001] The present application relates to the technical field of linear guide rails, and in particular to a guide rail slider device and a processing technology thereof. Background Art

[0002] The function of linear guide motion is to support and guide moving parts to make reciprocating linear motion in a given direction. According to the nature of friction, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides and other types. Sliding friction guides have more applications in the mechanical field due to their simple structure.

[0003] The existing linear guide mechanism mainly includes a guide rail and a slider. The slider is slidably arranged on the guide rail and cooperates with the guide rail. In order to reduce the friction between the slider and the guide rail, lubricating oil is usually applied to the guide rail. However, as the slider slides between the guide rail, the lubricating oil on the guide rail is squeezed to both sides of the guide rail, resulting in a continuous reduction in the lubricating oil between the slider and the guide rail. However, it is difficult to apply the lubricating oil in time manually, resulting in poor lubrication effect between the slider and the guide rail. Summary of the invention

[0004] In order to improve the problem that it is difficult to manually apply lubricating oil in time, resulting in poor lubrication effect between the slider and the guide rail, the present application provides a guide rail slider device and a processing technology thereof.

[0005] On the one hand, the present application provides a guide rail slider device adopts the following technical solution: A guide rail slider device comprises a guide rail and a slider sliding on the guide rail, the slider comprising a connecting portion, a sliding portion and a lateral limiting portion, the guide rail is provided with a sliding groove and a lateral limiting groove, the sliding portion is slidably arranged in the sliding groove to form a support for the slider, and the lateral limiting portion is slidably arranged in the lateral limiting groove to limit the slider from being separated from the guide rail; The sliding block is provided with an oil storage cavity for storing lubricating oil, the bottom of the sliding portion is provided with a wedge-shaped component, the wedge-shaped component can form a wedge-shaped space with the bottom wall of the sliding groove, the sliding block is provided with a refueling channel, the oil inlet of the refueling channel is connected with the oil storage cavity, and the oil outlet of the refueling channel is located in front of the wedge-shaped space so as to be able to supply oil to the wedge-shaped space.

[0006] By adopting the above technical scheme, the slider is first assembled to the guide rail, and 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, and then lubricating oil is added to the oil storage chamber. When the slider slides, the lubricating oil flows into the large opening of the wedge-shaped space along the oil filling channel and flows out from the small opening. On the one hand, lubrication of the sliding between the slider and the bottom wall of the sliding groove is achieved. 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 scheme uses the lubricating oil in the oil storage chamber to lubricate 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 a specific possible implementation manner, the number of the wedge-shaped components is two groups, and the large openings of the wedge-shaped spaces formed by the two groups of wedge-shaped components face opposite directions.

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

[0009] In a specific possible implementation scheme, the wedge assembly includes a positive portion fixedly arranged at the bottom of the sliding portion, and the positive portion is provided with an inclined surface on the side facing the bottom wall of the sliding groove, and the wedge-shaped space is formed between the inclined surface and the bottom wall of the sliding groove, and the large-mouth side of the wedge-shaped space is provided with an oil inlet chamber connected to the oil outlet of the refueling channel, and the small-mouth side of the wedge-shaped space is provided with an oil return chamber, and the oil return chamber is connected to the refueling channel through the oil return 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, and the lubricating oil flows into the oil inlet chamber in front of the wedge-shaped space, and then flows into the oil return chamber through the wedge-shaped space. At this time, the pressure of the lubricating oil in the oil return chamber increases, and a part of the lubricating oil returns to the refueling channel through the oil return channel, thereby achieving full use of the lubricating oil.

[0011] In a specific possible implementation manner, the distance from the inclined surface to the bottom wall of the sliding groove is greater than the distance from the sliding portion 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 fits against the bottom wall of the sliding groove to form support for the slider. On the one hand, it can improve the stability of the connection between the slider and the guide rail, and on the other hand, it can retain the lubricating oil in the wedge-shaped space, thereby improving the utilization rate of the lubricating oil when the slider slides.

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

[0014] By adopting the above technical solution, as the lubricating oil is used, the debris in the lubricating oil gradually increases, and the lubricating oil in the sliding groove needs to be discharged and the lubricating oil needs to be replaced. At this time, the outlet hole is opened through 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 a specific possible implementation scheme, the switch control element corresponds to the oil outlet hole one by one; The switch control component includes a mounting tube and a blocking rod. The mounting tube is fixedly mounted on the guide rail and is connected to the oil outlet. The mounting tube is provided with an oil outlet strip-shaped hole. The blocking rod is slidably penetrated on the mounting tube and inserted into the oil outlet so as to be able to block the oil outlet. A fixing nut is threadedly sleeved on the mounting tube, and the fixing nut is connected to the blocking rod so as to be able to drive the blocking rod to be inserted into or withdrawn from the oil outlet.

[0016] By adopting the above technical solution, when controlling the oil outlet hole, the fixing nut is rotated, and the fixing nut drives the sealing rod to be inserted into the oil outlet hole to seal the oil outlet hole; the fixing nut is rotated in the opposite direction, and the fixing nut drives the sealing rod to be pulled out of the oil outlet hole to open the oil outlet hole, thereby realizing the control of the opening and closing of the oil outlet hole; by setting the oil outlet strip hole, the flow distance of the lubricating oil in the mounting tube is reduced, which facilitates the discharge of the lubricating oil.

[0017] In a specific possible implementation scheme, a baffle is fixedly provided at the end of the blocking rod, and the baffle is fixedly connected to the fixing nut via a telescopic spring.

[0018] In a specific possible implementation scheme, a driving block is provided on the slider, and the driving block is used to squeeze the telescopic spring to contract so as to insert the blocking rod at the corresponding position of the slider into the oil outlet.

[0019] By adopting the above technical solution, when the lubricating oil in the sliding groove is replaced, the driving slider is driven to slide 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 of the oil outlet hole, thereby speeding up the replacement of the lubricating oil; when the slider slides to the corresponding oil outlet hole position, the driving block drives the blocking rod to insert into the oil outlet hole to block the oil outlet hole, thereby ensuring the effect of the lubricating oil on the slider when flowing through the wedge-shaped space.

[0020] In a specific possible implementation manner, guide surfaces are provided on both ends of the driving block, the blocking rod can slide onto the guide surfaces, and the guide surfaces can guide the blocking rod to be inserted into the oil outlet hole.

When the slider slides, the lubricating oil flows in along the large opening of the wedge-shaped space of the oil filling channel and flows out from the small opening. On the one hand, the lubrication between the slider and the bottom wall of the sliding groove is realized. 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.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-6 This application is described in further detail.

[0032] The embodiment of the present 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 sliding on the guide rail 1. The slider 2 includes a connecting portion 21, a sliding portion 22 and a lateral limiting portion 23. The lateral limiting portion 23 is in two groups and is located at both sides of the connecting portion 21, and the sliding portion 22 is located at the bottom of the connecting portion 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. There are two lateral limiting grooves 12, which are located at both sides of the sliding groove 11 and correspond to the lateral limiting portions 23 one by one. The sliding portion 22 is slidably arranged in the sliding groove 11 to form a support for the slider 2. The guide rail 1 is provided with two limit blocks 13 at both ends of the sliding groove 11, each of which is fixedly connected to the guide rail 1 by bolts. The two limit blocks 13 are used to block the two ends of the sliding groove 11, so as to prevent the slider 2 from being separated from the guide rail 1. The lateral limiting portion 23 is slidably arranged in the lateral limiting groove 12 to limit the block from being separated from the guide rail 1.

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

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

[0036] First, assemble the slider 2 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 component 3 and the bottom wall of the sliding groove 11, and then add lubricating oil into the oil storage chamber 211. When the slider 2 slides, the lubricating oil flows into the large opening of the wedge-shaped space 4 along the refueling channel 24 and flows out from the small opening. On the one hand, lubrication of the sliding between the slider 2 and the bottom wall of the sliding groove 11 is achieved. 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 chamber 211 to lubricate 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.

[0037] Reference Figure 1 , Figure 3 In this embodiment, there are two groups of wedge components 3, which are arranged at the bottom of the sliding part 22 along the sliding direction of the slider 2. Each group of wedge components 3 includes a positive part 31, and the positive part 31 is provided with an inclined surface 32 on the side facing the bottom wall of the sliding groove 11. The two groups of inclined surfaces 32 are inclined in opposite directions, so that the large openings of the wedge space 4 formed between the two groups of inclined surfaces 32 and the bottom wall of the sliding groove 11 face in opposite directions. By setting the large openings of the two groups of wedge spaces 4 to face in opposite directions, when the slider 2 slides in both directions, the lubricating oil can generate an upward thrust on the slider 2, 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, so that when the slider 2 is stationary, the bottom wall of the slider 2 fits with the bottom wall of the sliding groove 11 to form a support for the slider 2, which can improve the stability of the connection between the slider 2 and the guide rail 1 on the one hand, and can keep the lubricating oil in the wedge space 4 on the other hand, thereby improving the utilization rate of the lubricating oil when the slider 2 slides.

[0038] Reference Figure 1 , Figure 3Two groups of oil inlet chambers 33 and oil return chambers 34 are provided at the bottom of the sliding portion 22. Each wedge-shaped space 4 corresponds to an oil inlet chamber 33 and an oil return chamber 34. The oil inlet chamber 33 is located on the large-mouth side of the wedge-shaped space 4, and the oil return chamber 34 is located on the small-mouth 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 flows into the oil return chamber 34 through the wedge-shaped space 4. At this time, the pressure of the lubricating oil in the oil return chamber 34 increases, and a part of the lubricating oil returns to the refueling channel 24 through the oil return channel 35, thereby achieving full use 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 tilted to one side, so that one side of the bottom wall of the sliding groove 11 is high and the other side is low. A plurality of oil outlet holes 5 are provided on the guide rail 1, and the plurality of oil outlet holes 5 are arranged at intervals along the length direction of the guide rail 1. Each oil outlet hole 5 is located at the lowest side of the sliding groove 11, so that the lubricating oil can flow out of the sliding groove 11.

[0041] Reference Figure 1 , Figure 4 and Figure 5 The guide rail 1 is provided with a switch control member 6 for controlling the opening and closing of the oil outlet hole 5, and the switch control member 6 corresponds to the oil outlet hole 5. The switch control member 6 in this embodiment includes a mounting tube 61 and a blocking rod 62, and the mounting tube is fixedly mounted on the side wall of the guide rail 1 and is connected to the oil outlet hole 5.

[0042] Reference Figure 6 An oil outlet strip hole 611 is provided at the bottom of the mounting tube 61. When the lubricating oil flows into the mounting tube 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 tube 61 and facilitating the discharge of the lubricating oil.

[0043] Reference Figure 5 , Figure 6The sealing rod 62 is slidably penetrated on the mounting tube 61 and inserted into the oil outlet hole 5 to seal the oil outlet hole 5. A fixing nut 63 is threadedly sleeved on the mounting tube 61. A baffle 64 is fixedly provided at the end of the sealing rod 62. The baffle 64 and the fixing nut 63 are fixedly connected by a telescopic spring 65. When the oil outlet hole 5 needs to be sealed, the fixing nut 63 is rotated to move toward the guide rail 1. The fixing nut 63 pulls the sealing rod 62 into the oil outlet hole 5 through the telescopic spring 65, thereby sealing the oil outlet hole 5. When the oil outlet hole 5 needs to be opened, 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 hole 5 through the telescopic spring 65, thereby opening the oil outlet hole 5.

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

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

[0046] When replacing the lubricating oil in the sliding groove 11, the driving slider 2 is driven to slide 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 of the oil outlet hole 5, thereby speeding up the replacement of the lubricating oil; when the slider 2 slides to the position corresponding to the oil outlet hole 5, the driving block 66 drives the blocking rod 62 to insert into the oil outlet hole 5 to block the oil outlet hole 5, thereby ensuring the effect of the lubricating oil on the slider 2 when flowing through the wedge-shaped space 4.

[0047] The implementation principle of a guide rail slider device in an embodiment of the present application is as follows: first, the slider 2 is assembled to the guide rail 1, at which time the sliding portion 22 is inserted into the sliding groove 11, and the lateral limiting portion 23 is inserted into the lateral limiting groove 12. At this time, a wedge-shaped space 4 is formed between the wedge component 3 and the bottom wall of the sliding groove 11, and then lubricating oil is added to the oil storage chamber 211. When the slider 2 slides, the lubricating oil flows into the large opening of the wedge-shaped space 4 along the refueling channel 24 and flows out from the small opening. On the one hand, lubrication of the sliding between the slider 2 and the bottom wall of the sliding groove 11 is achieved. 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 chamber 211 to lubricate 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.

[0049] A processing technology of a guide rail slider device, using the above-mentioned guide rail slider device, comprises the following steps: S1. Material preparation: prepare the raw materials of the slider 2 and the guide rail 1, usually aluminum alloy, steel, etc. The materials need to be inspected before processing to ensure that the material quality meets the requirements.

Processing needs to be carried out according to the requirements of the product to ensure processing accuracy and surface finish.

[0051] S3, surface treatment, the surface of the guide rail and the slider 2 is treated, such as sandblasting, polishing, electroplating, etc. Surface treatment can improve the surface finish and corrosion resistance of the product, and also beautify the appearance of the product.
