Description

Technical Field

[0001] This invention relates to the field of guide rail slider lubrication technology, specifically to a lubrication device for linear guide rail sliders and its usage method. Background Technology

[0002] Linear guides, also known as linear rails or slide rails, are mainly used in linear reciprocating motion applications. They can achieve high-precision linear motion under high loads. Linear guides are mostly used in automated machinery. There is friction between the guide rail and the slider, so a lubrication device is needed to lubricate the linear guide rail. However, existing guide rail slider lubrication devices generally rely on direct observation of the lubrication status of the guide rail slider to determine whether lubrication is needed. Furthermore, each time lubrication is required, the slider needs to be stopped and an oil nozzle connected for lubrication. This is inconvenient for timely lubrication of the guide rail slider and reduces lubrication efficiency.

[0003] The existing guide rail slider lubrication device has the following defects:

[0004] 1. In patent document JP2005207467A, the main consideration is to avoid shortening the effective formation of the linear guide rail. However, it does not consider the problem of determining whether a lubrication device is needed by observing the slider running device, which makes it inconvenient to lubricate the guide rail slider in a timely manner.

[0005] 2. Patent document KR1020130119362A mainly considers how the lubricating oil flows, but does not consider the detection of lubrication flow rate and margin.

[0006] 3. In patent document CN109899400B, the main consideration is how to extend the time for replenishing lubricating oil, and the problem of not using a lubrication device to lubricate the linear guide slider is that it is inconvenient to clean the guide rail.

[0007] 4. Patent document CN107269694B mainly considers how to control the amount of lubricating oil released, but does not consider the problem of inconvenience in replacing the coated parts after the debris and residue adhere to them. Summary of the Invention

[0008] The purpose of this invention is to provide a lubrication device and its method of use for a linear guide slider, so as to solve the problem mentioned in the background art that the existing lubrication devices are not convenient for timely lubrication of the guide slider and reduce the lubrication efficiency.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a lubrication device for a linear guide slider, comprising: a slider body, a guide body, and a lubrication assembly, wherein the slider body is slidably connected to the outer wall of the guide body, and the lubrication assembly is installed on both the front and back sides of the slider body, and a lubrication status detection module is installed on the front side of the lubrication assembly;

[0010] The lubrication status detection module includes an acceleration sensor control module, and the acceleration sensor is electrically connected to the control module. A warning module is provided on the front of the lubrication assembly, and the warning module is located to the right of the acceleration sensor and is electrically connected to the acceleration sensor. An oil storage chamber is installed on the inner wall of the lubrication assembly, and a lubricating oil pipe is connected through the outer wall of the oil storage chamber. A solenoid valve is provided inside the lubricating oil pipe and is electrically connected to the control module.

[0011] The inner wall of the slider body is equipped with a support block, and an oil outlet channel is provided through the inside of the support block. One end of the oil outlet channel is connected to a lubricating oil pipe. The outer wall of the support block is slidably connected with ball bearings to reduce the friction between the slider body and the guide rail body.

[0012] Preferably, a flow meter is installed inside the lubricating oil pipe and is located below the solenoid valve. A liquid level sensor is installed through the outer wall of the oil storage chamber. An air bladder is installed on the top of the inner wall of the oil storage chamber. A lifting plate is connected to the bottom of the air bladder. A spring is fixedly installed on the top of the inner wall of the oil storage chamber and is located between the two sets of air bladders. A protective box is fixedly installed on the top of the lubrication assembly. A miniature air pump is installed on the inner wall of the protective box and is connected to the air bladder through an air inlet pipe.

[0013] Preferably, the flow meter is electrically connected to the warning module and the control module, the micro air pump is electrically connected to the control module, and the liquid level sensor is electrically connected to the warning module.

[0014] Preferably, a mounting frame is fixedly installed on the front of the lubrication component, and the mounting frame is located on both sides of the guide rail body. Limiting holes are provided through the outer wall of the mounting frame. A push-pull block is slidably connected to the inner wall of the mounting frame. Spring 2 is installed at the bottom of the upper push-pull block and the top of the lower push-pull block, and one end of spring 2 is connected to the inner wall of the mounting frame. Spring 3 is fixedly installed on the inner wall of the push-pull block. A protrusion is connected to one end of spring 3, and the protrusion penetrates through the inner wall of the push-pull block. A connecting rod is movably connected to the outer wall of the push-pull block. A housing is movably connected to the end of the connecting rod away from the push-pull block. A cleaning plate is detachably installed on the inner wall of the housing.

[0015] Preferably, the lubrication component has a guide groove on its front side and a guide rod is fixedly installed on the back side of the housing, and the guide rod is slidably connected to the inner wall of the guide groove.

[0016] Preferably, a fixing rod is fixedly installed on the inner wall of the outer shell, and the fixing rod penetrates the outer wall of the cleaning plate. An insert rod is connected through the outer wall of the outer shell, and a spring four is installed on the outer wall of the outer shell, with the left end of the spring four fixedly connected to the outer wall of the insert rod.

[0017] Preferably, the outer walls on both sides of the guide rail body are provided with grooves, and the outer walls of the grooves are slidably connected to the balls.

[0018] Preferably, the outer wall of the lubrication component is provided with an oil injection port, and the oil injection port penetrates the outer wall of the oil storage cavity.

[0019] Preferably, the lubrication device is used as follows:

[0020] S1. Install the lubrication components on the front and back of the slider body with bolts, and inject lubricating oil into the oil storage chamber through the oil inlet;

[0021] S2. The drive motor drives the slider body to slide along the outer wall of the guide rail body. The acceleration of the slider body is measured by an acceleration sensor. According to Newton's second law: f = ma, the frictional force between the slider body and the guide rail body is obtained.

[0022] Where m: the total mass of the slider body or the slider body and its load, a: the acceleration of the slider movement measured by the accelerometer, and f: the frictional force between the slider body and the guide rail body.

[0023] When the frictional force exceeds the standard frictional force, the warning module will issue a warning, indicating that the guide rail slider needs to be lubricated;

[0024] S3. When the slider body slides forward along the guide rail body, the squeeze push-pull blocks slide along the inner wall of the mounting frame and move closer to each other, squeezing the second spring. The push-pull blocks push the connecting rod to rotate, and the connecting rod pushes the outer shell to move the cleaning plate, so that the cleaning plate fits against both sides of the guide rail body to clean the guide rail body.

[0025] S4. When the solenoid valve is opened, the lubricating oil enters the oil outlet channel through the lubricating oil pipe and flows outward to lubricate the balls that are attached to the outer wall of the support block, and the lubricating oil is applied to the inner wall of the groove.

[0026] S5. The level sensor detects the amount of lubricating oil in the oil storage chamber. When the lubricating oil level is too low, the warning module issues an insufficient oil warning, prompting the user to add lubricating oil in time.

[0027] Preferably, step S5 further includes the following steps:

[0028] S51. The flow meter measures the amount of lubricating oil used, and the lubricating oil flow rate is obtained according to the formula for calculating flow rate and velocity: Q = SV.

[0029] Where Q: flow rate, S: cross-sectional area of ​​the lubricating oil pipe, V: flow velocity.

[0030] When the flow rate of lubricating oil in the lubricating oil pipe is low, the warning module issues a warning and sends a control command to the micro air pump. The micro air pump inflates the air bag, pushes the lifting plate downward, applies pressure to the lubricating oil, and accelerates the flow of lubricating oil.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1. This invention, by installing an acceleration sensor, an alarm module, and an oil reservoir, indirectly measures the frictional force of the guide rail slider during operation through the acceleration sensor. When the frictional force exceeds the standard frictional force, the alarm module issues a lubrication status warning. The control module controls the solenoid valve to open, allowing lubricating oil to flow into the support block through the lubrication pipe and then outward along the oil outlet channel, thus lubricating the slider body. During the movement of the slider body, the lubricating oil is also applied to the inner wall of the groove to lubricate the guide rail body. This invention facilitates monitoring the lubrication status of the slider body and allows for timely lubrication of the linear guide rail slider, avoiding untimely lubrication that could cause wear to the slider or guide rail.

[0033] 2. This invention, equipped with a flow meter, a liquid level sensor, and a lifting plate, features a warning module that issues a slow flow warning when the lubricating oil flow rate in the lubricating oil pipe is low. The control module then sends a control command to a micro air pump, which inflates the air bladder, pushing the lifting plate downwards. This increases the pressure in the oil storage chamber, accelerating the flow of lubricating oil and improving lubrication efficiency. The liquid level sensor detects the amount of lubricating oil in the storage chamber. When the lubricating oil level is too low, the warning module issues an insufficient oil warning, prompting the operator to add lubricating oil to the storage chamber in a timely manner to prevent insufficient lubrication and reduced lubrication effect on the linear guide slider.

[0034] 3. This invention uses an installation frame, a cleaning plate, and protrusions. When two sets of push-pull blocks are pressed, they slide and move closer to each other. The push-pull blocks move the protrusions to one side of the limiting hole. The spring pushes the protrusions to move and insert them into the inner wall of the limiting hole, fixing the push-pull blocks in place. The push-pull blocks push the connecting rod to rotate, and the connecting rod pushes the outer shell to move the cleaning plate horizontally. This causes the outer wall of the cleaning plate with the brush to fit against the outer walls of both sides of the guide rail body. This achieves the purpose of cleaning both sides of the guide rail body and the inner wall of the groove before lubrication, avoiding excessive dust on the outer wall of the guide rail body and wear on the outer wall of the slider body.

[0035] 4. This invention, by installing a fixed rod, an insert rod, and a spring, moves the insert rod closer to the connecting rod, causing it to detach from the inner wall of the fixed rod and stretch the spring. The insert rod slides along the outer wall of the cleaning plate until it separates from the outer wall of the cleaning plate, pulling the cleaning plate forward and separating it from the inner wall of the outer shell. This facilitates the removal and timely replacement of the cleaning plate, achieving the purpose of easy disassembly and installation of the cleaning plate, improving the efficiency of cleaning plate replacement, and helping to improve the cleanliness of the guide rail before the lubrication assembly lubricates the slider guide rail.

[0048] Please see Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a lubrication device for a linear guide slider, comprising: a slider body 1, a guide body 2, and a lubrication component 3. The slider body 1 is slidably connected to the outer wall of the guide body 2. The lubrication component 3 is installed on both the front and back sides of the slider body 1. The lubrication component 3 is detachably installed on the front and back sides of the slider body 1 by bolts. A lubrication status detection module is installed on the front side of the lubrication component 3.

[0049] The lubrication status detection module includes an acceleration sensor 4. A control module is provided on the front of the lubrication assembly 3 and is electrically connected to the acceleration sensor 4. A warning module 5 is provided on the front of the lubrication assembly 3 and is located to the right of the acceleration sensor 4. Three warning modules 5 are installed, and the upper warning module 5 is electrically connected to the acceleration sensor 4. An oil storage chamber 6 is installed on the inner wall of the lubrication assembly 3. A lubricating oil pipe 7 is connected through the outer wall of the oil storage chamber 6. A solenoid valve 8 is provided inside the lubricating oil pipe 7 and is electrically connected to the control module.

[0050] A support block 9 is installed on the inner wall of the slider body 1. The two sides of the support block 9 are arc-shaped. An oil outlet channel 10 is provided through the inside of the support block 9, and one end of the oil outlet channel 10 is connected to the lubricating oil pipe 7. A ball bearing 11 is slidably connected to the outer wall of the support block 9. The ball bearing 11 fits against the outer wall of the guide rail body 2 to reduce the friction between the slider body 1 and the guide rail body 2.

[0051] Furthermore, by installing an accelerometer sensor 4, when the drive motor drives the slider body 1 to slide along the outer wall of the guide rail body 2, the accelerometer sensor 4 measures the acceleration of the slider and transmits the measurement data to the control module. According to Newton's second law: f = ma, the frictional force between the slider body 1 and the guide rail body 2 is obtained.

[0052] Where m: the total mass of slider body 1 or slider body 1 and slider load, a: the acceleration of slider movement measured by accelerometer 4, and f: the frictional force between slider body 1 and guide rail body 2.

[0053] When the frictional force exceeds the standard frictional force, the control module sends a control command to the warning module 5. The warning module 5 then issues a lubrication status warning, indicating that the guide rail slider needs lubrication. The control module controls the solenoid valve 8 to open, and under the action of gravity, the lubricating oil flows into the support block 9 through the lubrication pipe 7 and then flows outward along the oil outlet channel 10. This lubricates the ball bearings 11 inside the slider body 1. During the slider's movement, the lubricating oil is also applied to the inner wall of the groove 33 on the outer wall of the guide rail body 2, thus lubricating the guide rail body 2. This facilitates the monitoring of the lubrication status of the slider body 1 and allows for timely lubrication of the linear guide rail slider.

[0054] Please see Figure 1 , Figure 3 and Figure 4One embodiment of the present invention provides a lubrication device for a linear guide slider, comprising: a flow meter 12 installed inside a lubricating oil pipe 7, the flow meter 12 being located below a solenoid valve 8; a liquid level sensor 13 being installed through the outer wall of an oil storage chamber 6, the liquid level sensor 13 being located near the bottom of the oil storage chamber 6; two air bladders 15 being installed on the top of the inner wall of the oil storage chamber 6; a lifting plate 14 being connected to the bottom of the air bladders 15, the lifting plate 14 being slidably connected to the inner wall of the oil storage chamber 6; and a spring 16 being fixedly installed on the top of the inner wall of the oil storage chamber 6. Two springs 16 are installed, and the springs 16 are located between the two sets of air bags 15. The bottom end of the springs 16 is fixedly connected to the top of the lifting plate 14. A protective box 17 is fixedly installed on the top of the lubrication assembly 3. A micro air pump 18 is installed on the inner wall of the protective box 17. A battery is installed at the bottom of the inner wall of the protective box 17. The protective box 17 provides protection for the micro air pump 18 and the battery. The micro air pump 18 is connected to the air bag 15 through the air inlet pipe. The flow meter 12 is electrically connected to the warning module 5 and the micro air pump 18. The liquid level sensor 13 is electrically connected to the warning module 5.

[0055] Furthermore, the flow meter 12 measures the amount of lubricating oil used, and based on the formula for calculating flow rate and velocity: Q = SV, the flow velocity of the lubricating oil in the lubricating oil pipe 7 is obtained.

[0056] Where Q: flow rate, S: cross-sectional area of ​​lubricating oil pipe 7, V: flow velocity.

[0057] When the flow rate of lubricating oil in the lubricating oil pipe 7 is low, the warning module 5 issues a warning for slow flow. The control module sends a control command to the micro air pump 18, which inflates the air bag 15, pushing the lifting plate 14 downward. This increases the pressure in the oil storage chamber 6, applies pressure to the lubricating oil, accelerates the flow of lubricating oil, and improves lubrication efficiency. The level sensor 13 detects the amount of lubricating oil in the oil storage chamber 6. When the amount of lubricating oil is too low, the warning module 5 issues an insufficient oil warning, prompting the staff to add lubricating oil to the oil storage chamber 6 in time to avoid insufficient lubricating oil and reduced lubrication effect on the linear guide slider.

[0058] Please see Figure 1 , Figure 5 and Figure 6An embodiment of the present invention provides a lubrication device for a linear guide slider, comprising: a mounting frame 19 fixedly mounted on the front of a lubrication assembly 3, wherein two mounting frames 19 are symmetrically arranged on both sides of the guide body 2, and a limiting hole 27 is provided through the outer wall of the mounting frame 19, the limiting hole 27 being located on the side of the mounting frame 19 away from the guide body 2; a push-pull block 20 is slidably connected to the inner wall of the mounting frame 19, and two sets of push-pull blocks 20 are slidably mounted on the inner wall of each set of mounting frames 19, the push-pull blocks 20 being L-shaped and penetrating the inner wall of the mounting frame 19 and extending to the outside of the mounting frame 19; a second spring 24 is installed at the bottom of the upper push-pull block 20 and the top of the lower push-pull block 20, and one end of the second spring 24 is connected to the mounting frame 19. The inner wall of the push-pull block 20 is connected to a spring 25, one end of which is connected to a protrusion 26, which penetrates the inner wall of the push-pull block 20. The outer wall of the push-pull block 20 is movably connected to a connecting rod 21, and the end of the connecting rod 21 away from the push-pull block 20 is movably connected to a housing 22. The inner wall of the housing 22 is detachably equipped with a cleaning plate 23, and a brush is provided on the side of the cleaning plate 23 near the outer wall of the guide rail body 2. The front of the lubrication component 3 is provided with a guide groove 29, which is symmetrically arranged about both sides of the guide rail body 2. The back of the housing 22 is fixedly equipped with a guide rod 28, which is slidably connected to the inner wall of the guide groove 29. By setting the guide rod 28 and the guide groove 29, the housing 22 and the cleaning plate 23 are guided.

[0059] Furthermore, before lubricating the linear guide, the cleaning plate 23 is attached to the outer wall of the guide body 2 to lubricate both sides of the guide body 2 and the inner wall of the groove 33. When the slider body moves forward, the cleaning plate 23 connected to the outer wall of the lubrication assembly 3 on the front side of the slider body is adjusted. By pressing the two sets of push-pull blocks 20 to slide along the inner wall of the mounting frame 19, the second spring 24 is squeezed and brought closer to each other, so that the push-pull blocks 20 drive the protrusion 26 to move to the side of the limiting hole 27. The third spring 25 pushes the protrusion 26 to move along the inner wall of the push-pull block 20, so that the protrusion 26 passes through the push-pull block 20. The outer wall is inserted into the inner wall of the limiting hole 27 to fix the push-pull block 20. The push-pull block 20 pushes the connecting rod 21 to rotate, the connecting rod 21 pushes the outer shell 22 to move, and the outer shell 22 drives the guide rod 28 to move along the inner wall of the guide groove 29, so that the guide rod 28 guides the outer shell 22, so that the outer shell 22 drives the cleaning plate 23 to move horizontally, so that the outer wall of the cleaning plate 23 with the brush side is in contact with the outer walls of both sides of the guide rail body 2, cleaning the two sides of the guide rail body 2 and the inner wall of the groove 33, avoiding excessive dust on the outer wall of the guide rail body 2, which would cause wear on the outer wall of the guide rail body 2 and the inner wall of the slider body.

[0060] Please see Figure 5 and Figure 7The present invention provides an embodiment of a lubrication device for a linear guide slider, comprising: a fixing rod 30 fixedly installed on the inner wall of a housing 22, the number of fixing rods 30 being several sets, and the fixing rod 30 penetrating the outer wall of a cleaning plate 23; an insert rod 31 penetrating and connecting to the outer wall of the housing 22; a spring 32 installed on the outer wall of the housing 22, and the left end of the spring 32 being fixedly connected to the outer wall of the insert rod 31; by setting the spring 32, the housing 22 and the insert rod 31 are connected; the outer wall of the insert rod 31 is slidably attached to and slidably connected to the outer wall of the cleaning plate 23; and the insert rod 31 penetrates the outer wall of the fixing rod 30.

[0061] Furthermore, by pulling the insertion rod 31 to move closer to the connecting rod 21, the insertion rod 31 disengages from the inner wall of the fixing rod 30 and stretches the spring 4 32. The insertion rod 31 slides along the outer wall of the cleaning plate 23 until it separates from the outer wall of the cleaning plate 23. The cleaning plate 23 is then pulled forward to separate it from the inner wall of the outer shell 22, making it easier to remove the cleaning plate 23 and replace it in time. During installation, the outer wall of the cleaning plate 23 is fitted against the inner wall of the outer shell 22, and the fixing rod 30 passes through the mounting hole on the outer wall of the cleaning plate 23. The insertion rod 31 is then released, and the spring 4 32 pulls the insertion rod 31 to slide along the outer wall of the cleaning plate 23 and through the outer wall of the fixing rod 30, limiting the fixing rod 30. This facilitates the disassembly and installation of the cleaning plate 23, improves the efficiency of replacing the cleaning plate 23, and helps improve the cleanliness of the guide rail before the lubrication assembly 3 lubricates the slider guide rail.

[0062] Please see Figure 2 and Figure 4 An embodiment of the present invention provides a lubrication device for a linear guide slider, comprising: grooves 33 formed on both outer walls of the guide body 2, the grooves 33 being arc-shaped and the outer walls of the grooves 33 being slidably connected to the balls 11; an oil inlet 34 provided on the outer wall of the lubrication component 3, the oil inlet 34 penetrating the outer wall of the oil storage cavity 6; and a one-way valve provided on the inner wall of the oil inlet 34. By providing the oil inlet 34, it is convenient to add lubricating oil into the oil storage cavity 6.

[0063] The lubrication device is used as follows:

[0064] S1. Install the lubrication assembly 3 on the front and back of the slider body 1 with bolts, and inject lubricating oil into the oil storage chamber 6 through the oil inlet 34;

[0065] S2. The drive motor drives the slider body 1 to slide along the outer wall of the guide rail body 2. The acceleration of the slider body 1 is measured by the acceleration sensor 4. According to Newton's second law: f = ma, the frictional force between the slider body 1 and the guide rail body 2 is obtained.

[0066] Where m: the total mass of slider body 1 or slider body 1 and slider load, a: the acceleration of slider movement measured by accelerometer 4, and f: the frictional force between slider body 1 and guide rail body 2.

[0067] When the frictional force exceeds the standard frictional force, the warning module 5 issues a warning, indicating that the guide rail slider needs to be lubricated;

[0068] S3. When the slider body 1 slides forward along the guide rail body 2, the push-pull block 20 slides along the inner wall of the mounting frame 19 and gets closer to each other, squeezing the spring 24. The push-pull block 20 pushes the connecting rod 21 to rotate. The connecting rod 21 pushes the outer shell 22 to move the cleaning plate 23, so that the cleaning plate 23 fits against both sides of the guide rail body 2 to clean the guide rail body 2.

[0069] S4. When the solenoid valve 8 is opened, the lubricating oil enters the oil outlet channel 10 through the lubricating oil pipe 7 and flows outward to lubricate the ball bearings 11 that are attached to the outer wall of the support block 9, and the lubricating oil is applied to the inner wall of the groove 33.

[0070] S5. The level sensor 13 detects the amount of lubricating oil in the oil storage chamber 6. When the amount of lubricating oil is too low, the warning module 5 issues an insufficient oil warning to prompt the timely addition of lubricating oil.

[0071] Step S5 further includes the following steps:

[0072] S51. Flow meter 12 measures the amount of lubricating oil used and, based on the formula for calculating flow rate and velocity: Q = SV, determines the lubricating oil flow rate.

[0073] Where Q: flow rate, S: cross-sectional area of ​​lubricating oil pipe 7, V: flow velocity.

[0074] When the flow rate of lubricating oil in the lubricating oil pipe 7 is low, the warning module 5 issues a warning and sends a control command to the micro air pump 18. The micro air pump 18 inflates the air bag 15, pushes the lifting plate 14 to move downward, applies pressure to the lubricating oil, and accelerates the flow of lubricating oil.

[0075] Working principle: The lubrication component 3 is installed on the front and back of the slider body 1 by bolts. Lubricating oil is injected into the oil storage cavity 6 through the oil injection port 34. The drive motor drives the slider body 1 to slide along the outer wall of the guide rail body 2. The acceleration of the slider body 1 is measured by the acceleration sensor 4. According to Newton's second law, the friction force between the slider body 1 and the guide rail body 2 is obtained. When the friction force is greater than the standard friction force, the warning module 5 issues a warning.

[0076] When adjusting the position of the cleaning plate 23, the push-pull block 20 slides along the inner wall of the mounting frame 19 and moves closer to each other by squeezing the second spring 24. The push-pull block 20 pushes the connecting rod 21 to rotate. The connecting rod 21 pushes the outer shell 22 to move the cleaning plate 23, so that the cleaning plate 23 fits against both sides of the guide rail body 2 and cleans the guide rail body 2.

[0077] The control module controls the solenoid valve 8 to open, and the lubricating oil enters the oil outlet channel 10 through the lubricating oil pipe 7 and flows outward to lubricate the ball bearings 11 that are attached to the outer wall of the support block 9, and applies the lubricating oil to the inner wall of the groove 33. The level sensor 13 detects the amount of lubricating oil in the oil storage chamber 6. When the amount of lubricating oil is too low, the warning module 5 issues an insufficient oil warning to prompt the timely addition of lubricating oil.

[0078] When the flow rate of lubricating oil in the lubricating oil pipe 7 is low, the warning module 5 issues a warning and sends a control command to the micro air pump 18. The micro air pump 18 inflates the air bag 15, pushes the lifting plate 14 to move downward, applies pressure to the lubricating oil, accelerates the flow of lubricating oil, and improves lubrication efficiency.
