Description

Technical Field

[0001] The utility model relates to the technical field of guide rails, in particular to a self-lubricating linear guide rail. Background Art

[0002] Due to advantages such as high precision, high rigidity and good load-bearing capacity, linear guide rails are key components widely used in fields such as precision instruments, automation equipment, and electronic manufacturing.

[0003] During operation, linear guide rails need to be lubricated regularly. If the linear guide rails are not properly lubricated and maintained, the friction between the steel balls and the surface of the slide rail grooves in the linear guide rails will increase, thus affecting the running accuracy and service life of the guide rails. The existing common lubrication methods include manual oil spraying lubrication and oil passage lubrication in the linear guide rails. When the linear guide rails are under high-temperature or high-speed working conditions, the staff needs to increase the lubrication frequency of the linear guide rails, and multiple linear guide rails are usually required in some process steps, increasing the labor intensity of the staff. Therefore, this application specifically proposes a self-lubricating linear guide rail that can reduce the oil injection frequency. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a self-lubricating linear guide rail that can protect the surface of the heating end.

[0005] To achieve the above purpose, the utility model provides a self-lubricating linear guide rail, including:

[0006] An oil storage cavity is arranged in the slider. The oil storage cavity is filled with a lubricating medium and is provided with an oil outlet on each side. Each oil outlet is arranged above the corresponding ball. Each oil outlet is provided with an inclined surface. An isolation cavity is also arranged between each oil outlet and the corresponding ball. A fuel injection nozzle is arranged on the slider for injecting oil into the oil storage cavity;

[0007] Two oil delivery components. The oil delivery component includes an oil delivery plate arranged in the corresponding oil outlet for blocking the oil outlet. The oil delivery plate is arranged along the length direction of the slider and has another set of inclined surfaces corresponding to the inclined surfaces of the corresponding oil outlet. When the oil delivery plate rises, a gap for the lubricating medium to flow out is generated between the oil delivery plate and the side wall of the corresponding oil outlet. An eccentric wheel is arranged below the oil delivery plate. The eccentric wheel is arranged in the isolation cavity. The eccentric wheel is used to push the oil delivery plate to move upward. A plurality of first elastic units are also distributed between the oil delivery plate and the isolation cavity for providing a downward pulling force for the oil delivery plate;

[0008] A rolling component is arranged in the slider. When the slider moves on the slide rail, the rolling component rotates together with the movement of the slider;

[0009] A transmission component is arranged inside the slider. The transmission component is connected to each of the eccentric wheels. One end of the transmission component is detachably connected to the rolling component. When the transmission component is connected to the rolling component, the rolling component drives the transmission component to rotate together. The transmission component is used to drive each of the eccentric wheels to rotate synchronously with the rolling component.

[0010] A control component is arranged inside the slider. The control component is in contact with the rolling component. The control component is used to control the connection and separation between the transmission component and the rolling component.

[0011] Further, the rolling component includes a plurality of rollers arranged inside the slider. The rollers are arranged corresponding to the eccentric wheels and on one side of the corresponding eccentric wheels close to the center of the slider. One end of each roller passes through the slider and contacts the top surface of the slide rail. A first transmission rod is disposed through each roller. One end of the first transmission rod is detachably connected to the transmission component, and the other end of the first transmission rod is connected to the control component. When the rollers rotate, the rollers drive the transmission component to rotate together through the first transmission rod.

[0012] Further, the transmission component includes a second transmission rod arranged in the isolation cavity corresponding to the eccentric wheel. The eccentric wheel is arranged on the corresponding second transmission rod. When the second transmission rod rotates, it drives the corresponding eccentric wheel to rotate. One end of the second transmission rod close to the center of the slider extends out of the isolation cavity and is connected to the corresponding first transmission rod. A switching member is further arranged between the second transmission rod and the corresponding first transmission rod. The switching member is used to control the connection or separation between the first transmission rod and the second transmission rod.

[0013] Further, the switching member includes a first abutting block arranged at one end of the first transmission rod close to the second transmission rod and a second abutting block arranged at one end of the second transmission rod close to the first transmission rod. When the first transmission rod rotates, the first abutting block rotates with the axis of the first transmission rod as the rotation center, and the end close to the second abutting block is chamfered. When the second transmission rod rotates, the second abutting block rotates with the axis of the second transmission rod as the rotation center, and the end close to the first abutting block is chamfered.

[0014] Further, the control component includes a third abutting block rotatably arranged at one end of the first transmission rod away from the corresponding second transmission rod. A connecting block is slidably arranged on the third abutting block and is located in the slider. The connecting block is used to prevent the third abutting block from rotating together with the first transmission rod. A positioning block is further arranged between the third abutting block and the corresponding roller. The positioning block is fixed in the slider and the first transmission rod slides through the corresponding positioning block. A second elastic unit is further arranged between the third abutting block and the positioning block. The second elastic unit provides a thrust for the third abutting block towards the center of the slider. It further includes a button assembly arranged on the side of the slider away from the oil injection nozzle. One end of the button assembly extends into the slider and is provided with an abutting rod. The abutting rod contacts the third abutting block. When the button assembly drives the abutting rod to move towards the oil injection nozzle, the abutting rod abuts against the third abutting block.

[0015] Further, the eccentric wheel is an eccentric cam provided with an inclined surface;

[0016] An adjusting component is further arranged in the slider. The adjusting component includes an adjusting block arranged on the bottom surface of the oil delivery plate. The adjusting block is arranged above the corresponding eccentric wheel. One end of the adjusting block close to the corresponding eccentric wheel is provided with a chamfer, and the chamfer corresponds to the inclined surface of the eccentric wheel. When the eccentric wheel rotates, the eccentric wheel abuts against the chamfer of the corresponding adjusting block and drives the oil delivery plate to move up and down reciprocally;

[0017] It further includes a threaded rod rotatably arranged on one side of the slider. One end of the threaded rod extends into the slider and is rotatably provided with a first connecting plate. The first connecting plate is slidably arranged in the slider. A second connecting plate is further slidably arranged in the slider. The second connecting plate is arranged opposite to the first connecting plate.

A third transmission rod is further arranged on the first connecting plate. The third transmission rod is arranged along the width direction of the slider and passes through the other isolation cavity and is connected to the second connecting plate. The end of the third transmission rod away from the threaded rod is provided with teeth. A gear meshing with the teeth on the third transmission rod is further arranged in the slider. A rack meshing with the gear is arranged below the gear. The rack is slidably arranged in the slider and one end of the rack is connected to the second connecting plate. When the threaded rod rotates, the threaded rod drives the first connecting plate and the third transmission rod to reciprocally move in the slider.

[0018] The beneficial effects of the present utility model are embodied in:

[0019] In this utility model, through the mutual cooperation between the rolling component and the transmission component, every time the slider moves a certain distance, the lubricating medium in the oil storage cavity flows out from the oil outlet and drips onto the ball to lubricate the ball. The mutual cooperation between the control component and the transmission component can control the opening or closing of the oil outlet. When lubrication is required, the staff only needs to open the oil outlet through the control component, reducing the manual oil injection frequency and alleviating the labor intensity of the staff.

[0030] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0031] See Figures 1-8 。

[0032] The present utility model discloses a self-lubricating linear guide rail, including:

[0033] An oil storage cavity 1 is arranged in the slider 7. The oil storage cavity 1 is filled with a lubricating medium and has an oil outlet 11 on each side. Each oil outlet 11 is arranged above the corresponding ball 71. Each oil outlet 11 is provided with an inclined surface. An isolation cavity 12 is also arranged between each oil outlet 11 and the corresponding ball 71. A fuel injection nozzle 13 is arranged on the slider 7 for injecting oil into the oil storage cavity 1;

[0034] Two oil delivery components 2. The oil delivery component 2 includes an oil delivery plate 21 arranged in the corresponding oil outlet 11 for blocking the oil outlet 11. The oil delivery plate 21 is arranged along the length direction of the slider 7 and has another set of inclined surfaces corresponding to the inclined surfaces of the corresponding oil outlet 11. When the oil delivery plate 21 rises, a gap for the lubricating medium to flow out is generated between the oil delivery plate 21 and the side wall of the corresponding oil outlet 11. An eccentric wheel 22 is arranged below the oil delivery plate 21. The eccentric wheel 22 is arranged in the isolation cavity 12. The eccentric wheel 22 is used to push the oil delivery plate 21 to move upward. A plurality of first elastic units 23 are also distributed between the oil delivery plate 21 and the isolation cavity 12 for providing a downward pulling force for the oil delivery plate 21;

[0035] A rolling component 3 is arranged in the slider 7. When the slider 7 moves on the slide rail 8, the rolling component 3 rotates together with the movement of the slider 7;

[0036] A transmission component 4 is arranged in the slider 7. The transmission component 4 is connected to each eccentric wheel 22. One end of the transmission component 4 is detachably connected to the rolling component 3. When the transmission component 4 is connected to the rolling component 3, the rolling component 3 drives the transmission component 4 to rotate together. The transmission component 4 is used to drive each eccentric wheel 22 to rotate synchronously with the rolling component 3;

[0037] A control component 5 is arranged in the slider 7. The control component 5 is in contact with the rolling component 3. The control component 5 is used to control the connection and separation between the transmission component 4 and the rolling component 3.

[0038] In specific implementation, the staff injects the lubricating medium into the oil storage cavity 1 through the oil injection nozzle 13. When lubrication is required, the control component 5 is used to connect the transmission component 4 with the rolling component 3. At this time, during the movement of the slider 7, the transmission component 4 drives each eccentric wheel 22 to rotate, and each eccentric wheel 22 drives the corresponding oil delivery plate 21 to reciprocate up and down in the oil outlet 11. When the oil delivery plate 21 rises, the first elastic unit 23 is stretched, and the lubricating medium flows out from the gap between the oil delivery plate 21 and the side wall of the corresponding oil outlet 11 and drips onto the ball 71. The ball 71 carries the lubricating medium and contacts the surface of the groove of the slide rail 8. As the ball 71 rolls, the lubricating medium forms an oil film between the ball 71 and the surface of the slide rail 8 to complete lubrication. When the lubrication is completed, the staff uses the control component 5 again to separate the transmission component 4 from the rolling component 3. The transmission component 4 no longer drives each eccentric wheel 22 to rotate. The first elastic unit 23 loses restraint at this time and drives the corresponding oil delivery plate 21 to move downward, so that the inclined surface of the oil delivery plate 21 abuts against the inclined surface at the corresponding oil outlet 11 and provides a downward pulling force for the oil delivery plate 21, thereby closing the oil outlet 11.

[0039] In the present utility model, through the mutual cooperation between the rolling component 3 and the transmission component 4, every time the slider 7 moves a certain distance, the lubricating medium in the oil storage cavity 1 flows out from the oil outlet 11 and drips onto the ball 71 to lubricate the ball 71. The mutual cooperation between the control component 5 and the transmission component 4 can control the opening or closing of the oil outlet 11. When lubrication is required, the staff only needs to open the oil outlet 11 through the control component 5, which reduces the manual oil injection frequency and lightens the labor intensity of the staff.

[0040] Preferably, the first elastic unit 23 can adopt a tension spring in the prior art.

[0041] Preferably, the lubricating medium can be selected as lubricating oil or the like.

[0042] It should be noted that when the transmission component 4 is separated from the rolling component 3, the pulling force of the first elastic unit 23 can drive the corresponding oil delivery plate 21 to move downward and closely adhere to the corresponding oil outlet 11, thereby avoiding the situation that when the transmission component 4 is separated from the rolling component 3, the eccentric wheel 22 accidentally jacks up the oil delivery plate 21 and the oil outlet 11 is not closed.

[0043] In an embodiment, the rolling component 3 includes a roller 31 disposed in the slider 7. The roller 31 corresponds to the position of the eccentric wheel 22 and is disposed on the side of the eccentric wheel 22 close to the center of the slider 7. One end of the roller 31 penetrates through the slider 7 and contacts the top surface of the slide rail 8. A first transmission rod 32 is disposed through the roller 31. One end of the first transmission rod 32 is separably connected to the transmission component 4, and the other end of the first transmission rod 32 is connected to the control component 5. When the roller 31 rotates, the roller 31 drives the transmission component 4 to rotate together through the first transmission rod 32.

[0044] With such a design, when lubrication is required, the control member 5 is used to connect the transmission member 4 to the first transmission rod 32. At this time, when the slider 7 moves, the roller 31 drives the transmission member 4 to rotate synchronously through the first transmission rod 32, and then the eccentric wheel 22 rotates synchronously.

[0045] In one embodiment, the transmission member 4 includes a second transmission rod 41 disposed in the isolation chamber 12 corresponding to the eccentric wheel 22, and the eccentric wheel 22 is disposed on the second transmission rod 41. When the second transmission rod 41 rotates, it drives the corresponding eccentric wheel 22 to rotate. One end of the second transmission rod 41 close to the center of the slider 7 extends out of the isolation chamber 12 and is connected to the corresponding first transmission rod 32. A switching member 42 is further disposed between the second transmission rod 41 and the corresponding first transmission rod 32, and the switching member 42 is used to control the connection or separation of the first transmission rod 32 and the second transmission rod 41.

[0046] With such a design, when lubrication is required, the control member 5 drives the first transmission rod 32 to move towards the corresponding second transmission rod 41. At this time, the switching member 42 connects each first transmission rod 32 and the second transmission rod 41, and the roller 31 drives the eccentric wheel 22 to rotate. When lubrication is not required, the control member 5 drives the first transmission rod 32 to move away from the corresponding second transmission rod 41. At this time, the switching member 42 separates the first transmission rod 32 and the second transmission rod 41, and the eccentric wheel 22 stops rotating. The elastic unit drives the corresponding oil delivery plate 21 to move downward and closes the oil outlet 11.

[0047] In one embodiment, the switching member 42 includes a first abutting block 421 disposed at one end of the first transmission rod 32 close to the second transmission rod 41 and a second abutting block 422 disposed at one end of the second transmission rod 41 close to the first transmission rod 32. When the first transmission rod 32 rotates, the first abutting block 421 rotates with the axis of the first transmission rod 32 as the rotation center, and the end close to the second abutting block 422 is chamfered. When the second transmission rod 41 rotates, the second abutting block 422 rotates with the axis of the second transmission rod 41 as the rotation center, and the end close to the first abutting block 421 is chamfered.

[0048] With this design, when the control component 5 connects the transmission component 4 with the rolling component 3, the first transmission rod 32 approaches the second transmission rod 41 and the rotation trajectory of the first abutment block 421 coincides with the rotation trajectory of the corresponding second abutment block 422. The first abutment block 421 rotates synchronously with the first transmission rod 32 until it abuts against the corresponding second abutment block 422. As the first transmission rod 32 continues to rotate, the first abutment block 421 drives the corresponding second transmission rod 41 to rotate synchronously through the second abutment block 422. When the first abutment block 421 abuts against the second abutment block 422 due to misalignment during the process of approaching the corresponding second abutment block 422, the chamfered design on each abutment block can enable the first abutment block 421 to continue to approach the second abutment block 422, and the chamfered surface of the second abutment block 422 contacts the chamfered surface of the first abutment block 421 and drives the second transmission rod 41 to rotate slightly until the second abutment block 422 is offset from the first abutment block 421.

[0049] In one embodiment, the control component 5 includes a third abutment block 51 rotatably arranged on one end of the first transmission rod 32 away from the corresponding second transmission rod 41, and the third abutment block 51 is provided with a connection block 511 slidably arranged in the slider 7, and the connection block 511 is used to prevent the third abutment block 51 from rotating together with the first transmission rod 32. A positioning block 52 is also provided between the third abutment block 51 and the corresponding roller 31, and the positioning block 52 is fixed in the slider 7 and the first transmission rod 32 slides and penetrates the corresponding positioning block 52. A second elastic unit 53 is also provided between the abutment block 51 and the positioning block 52. The second elastic unit 53 provides a thrust toward the center of the slider 7 for the corresponding third abutment block 51. It also includes a button assembly 54 arranged on the side of the slider 7 away from the oiling nozzle 13. One end of the button assembly 54 extends into the slider 7 and is provided with an abutment rod 55. The abutment rod 55 is in contact with the third abutment block 51. When the button assembly 54 drives the abutment rod 55 to move toward the direction close to the oiling nozzle 13, the abutment rod 55 abuts against the third abutment block 51.

[0050] With such a design, when lubrication is required, the button assembly 54 is pressed. The button assembly 54 drives the abutting rod 55 to move towards the oil injection nozzle 13. At this time, the abutting rod 55 abuts against the third abutting block 51 and applies a thrust to the third abutting block 51 to move it away from the center of the slider 7. At this time, the second elastic unit 53 is compressed. Each first transmission rod 32 approaches the corresponding second transmission rod 41 and is connected to the corresponding second transmission rod 41 through the switching member 42. The roller 31 drives the corresponding eccentric wheel 22 to rotate synchronously. When lubrication is not required, the button assembly 54 is pressed again. The button assembly 54 drives the abutting rod 55 to move away from the oil injection nozzle 13. At this time, the abutting rod 55 no longer abuts against the third abutting block 51. The second elastic unit 53 loses its restraint and drives the corresponding third abutting block 51 to move towards the center of the slider 7. At this time, the first transmission rod 32 is separated from the second transmission rod 41, and the eccentric wheel 22 stops rotating.

[0051] It should be noted that the button assembly 54 can refer to the pressing type pen cap of an existing ballpoint pen, and the structure of the ballpoint pen cap is used to drive the abutting rod 55 to reciprocate in the slider 7.

[0052] In one embodiment, the eccentric wheel 22 is an eccentric cam provided with an inclined surface;

[0053] The slider 7 is further provided with an adjusting member 6. The adjusting member 6 includes an adjusting block 61 arranged on the bottom surface of each oil delivery plate 21. The adjusting block 61 is arranged above the eccentric wheel 22. One end of the adjusting block 61 close to the corresponding eccentric wheel 22 is provided with a chamfer, and the chamfer corresponds to the inclined surface of the eccentric wheel 22. When the eccentric wheel 22 rotates, the eccentric wheel 22 abuts against the chamfer of the corresponding adjusting block 61 and drives the oil delivery plate 21 to reciprocate up and down;

[0054] It further includes a threaded rod 62 rotatably arranged on one side of the slider 7. One end of the threaded rod 62 extends into the slider 7 and is rotatably provided with a first connecting plate 63. The first connecting plate 63 is slidably arranged in the slider 7, and a second connecting plate 64 is also slidably arranged in the slider 7. The second connecting plate 64 is arranged opposite to the first connecting plate 63. The corresponding second transmission rod 41 arranged on the side close to the threaded rod 62 passes through the isolation cavity 12 and is rotatably connected to the first connecting plate 63. One end of the second connecting plate 64 close to the threaded rod 62 is rotatably connected to the remaining second transmission rod 41. A third transmission rod 65 is also arranged on the first connecting plate 63. The third transmission rod 65 is arranged along the width direction of the slider 7 and passes through another isolation cavity 12 to the second connecting plate 64. The end of the third transmission rod 65 away from the threaded rod 62 is provided with teeth. A gear 66 meshing with the teeth on the third transmission rod 65 is also arranged in the slider 7. A rack 67 meshing with the gear 66 is arranged below the gear 66. The rack 67 is slidably arranged in the slider 7 and one end of it is connected to the second connecting plate 64. When the threaded rod 62 rotates, the threaded rod 62 drives the first connecting plate 63 and the third transmission rod 65 to reciprocate in the slider 7.

[0055] With such a design, when it is necessary to adjust the oil output of the oil outlet 11, rotate the threaded rod 62. The threaded rod 62 drives the first connecting plate 63 and the third transmission rod to reciprocate in the slider 7. The second transmission rod 41 arranged on the first connecting plate 63 drives the corresponding eccentric wheel 22 to reciprocate. The teeth on the third transmission rod mesh with the gear 66 and drive the gear 66 to rotate. The gear 66 drives the second connecting plate 64 and the second transmission rod 41 arranged on the second connecting plate 64 to reciprocate together through the rack 67. By changing the position where each eccentric wheel 22 contacts the corresponding adjusting block 61 during rotation, the height of the corresponding oil delivery plate 21 during its up and down reciprocating movement is changed, thereby changing the oil output of the oil outlet 11. The chamfer design of the adjusting block 61 is used to reduce the occurrence of dead points when the eccentric wheel 22 rotates and contacts the corresponding adjusting block 61.

[0056] Preferably, a plurality of eccentric wheels 22, second transmission rods 41 and adjusting blocks 61 cooperating with the corresponding eccentric wheels 22 can be distributed below each oil delivery plate 21. Each eccentric wheel 22 is distributed along the length direction of the corresponding oil delivery plate 21. With such a design, the design of a plurality of eccentric wheels 22 can enable each oil delivery plate 21 to move more smoothly in the corresponding oil outlet 11.

[0057] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. In addition, "a plurality of", "multiple groups", "several" mean more than two.
