Description

Technical Field

[0001] The present invention belongs to the technical field of guide rail protection mechanisms, and specifically relates to a linear guide rail protection mechanism and a protection method therefor. Background Art

[0002] A linear slider, also known as a linear guide rail, slide rail, linear guide, or linear slide, is a linear transmission mechanism that is widely used in industrial automation equipment such as machinery, electronics, instruments, and meters.

[0003] In practical applications, linear sliders are easily affected by impurities such as metal debris, dust, and coolant. These external factors may interfere with the normal operation of the guide rail and even cause damage to the equipment. To ensure that the guide rail can work continuously and stably, a protection mechanism can effectively block the intrusion of these impurities, thereby keeping the guide rail clean and in good condition.

[0004] A bellows protective cover is a common type in linear guide rail protection mechanisms. This protective cover is usually composed of multiple layers of folded materials and is shaped like a bellows, hence the name. Its design allows it to maintain good sealing performance when stretching and contracting, effectively preventing the intrusion of impurities such as metal debris and dust, and at the same time, it can adapt to the movement of the guide rail without causing additional resistance to the normal operation of the guide rail.

[0005] Due to the bellows protective cover undergoing friction and wear during long-term and high-frequency stretching and contracting processes, gaps or deformations may occur, which in turn affect its reset performance, thereby leading to a problem of reduced protection effect on the linear guide rail. Summary of the Invention

[0006] The purpose of the present invention is to provide a linear guide rail protection mechanism and a protection method therefor to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the present invention provides the following technical solution: A linear guide rail protection mechanism includes a guide rail main body, a slider is slidably installed on the outer wall of the guide rail main body, and a protection component is arranged on the outer wall of the guide rail main body.

[0008] The protection component includes a protective cover arranged on the outer wall of the guide rail main body. Installation plates are installed at both ends of the protective cover. An auxiliary contraction component is arranged between the two installation plates. One of the installation plates is installed on the side wall of the slider, and a lubrication component is arranged inside the installation plate.

[0009] The auxiliary contraction assembly includes a connecting rope disposed between the two mounting plates. There are two symmetrically distributed connecting ropes. One end of each of the two connecting ropes is mounted on the outer wall of a winding roller. The winding roller is rotatably mounted inside one of the mounting plates. A torsion spring is provided between the winding roller and the mounting plate. The other ends of the two connecting ropes pass through the inside of the protective cover and are fixedly connected to the other mounting plate.

[0010] As a further technical solution of the present invention, the lubrication assembly includes a liquid storage cavity opened inside the mounting plate. A control assembly is provided inside the liquid storage cavity. Liquid guide pipes are uniformly embedded at the bottom of the liquid storage cavity. The bottom end of the liquid guide pipe is mounted with a mounting seat. A blowing assembly is provided inside the mounting seat. A sponge is fixedly mounted on the inner wall of the mounting seat. The sponge is disposed on the outer wall of the guide rail body.

[0011] As a further technical solution of the present invention, the control assembly includes a moving plate disposed inside the liquid storage cavity. A cam is provided inside the moving plate. The cam is fixedly mounted on the outer wall of the winding roller. The bottom end of the moving plate is fixedly connected to a connecting rod. The connecting rod is embedded inside the liquid guide pipe. The bottom end of the connecting rod is fixedly connected to a blocking block. A limiting block is provided at the bottom end of the blocking block. The limiting block is fixedly mounted on the inner wall of the liquid guide pipe.

[0012] As a further technical solution of the present invention, the moving plate is slidably mounted inside the liquid storage cavity. A tension spring is mounted between the moving plate and the liquid storage cavity.

[0013] As a further technical solution of the present invention, the mounting seat is disposed below the mounting plate. Connecting columns are mounted between the mounting seat and the mounting plate. The connecting columns are uniformly arranged.

[0014] As a further technical solution of the present invention, the bottom end of the connecting column is fixedly connected to a limiting plate. The limiting plate is slidably mounted inside the mounting seat. A spring is mounted between the limiting plate and the mounting seat.

[0015] As a further technical solution of the present invention, a telescopic pipe is mounted on the outer wall of the liquid guide pipe.

[0016] As a further technical solution of the present invention, the blowing assembly includes an airbag disposed inside the mounting seat. Exhaust pipes are uniformly mounted on the side wall of the airbag. A push plate is provided below the airbag. A reciprocating lead screw is meshed inside the inner wall of the push plate. The bottom end of the reciprocating lead screw is fixedly mounted with a first bevel gear. The bottom end of the first bevel gear is meshed with a second bevel gear. A rotating shaft is fixedly mounted inside the second bevel gear. One end of the rotating shaft is mounted with a gear. The bottom end of the gear is meshed with a rack plate. The rack plate is fixedly mounted on the top end of the guide rail body.

[0017] As a further technical solution of the present invention, an air inlet pipe is fixedly connected to the top end of the airbag, and the exhaust pipe is embedded inside the mounting seat.

[0018] A protection method for a linear guide rail protection mechanism includes the following steps:

[0019] S1: During operation, the slider slides on the outer wall of the guide rail main body. The movement of the slider drives the movement of one of the mounting plates. When the mounting plate moves, the protective cover is stretched. At the same time, during the movement of the mounting plate, the connecting rope unwinds on the outer wall of the winding roller and drives the winding roller to rotate. When the winding roller rotates, the coil spring deforms to store elastic potential energy.

[0020] S2: When the winding roller rotates, it drives the cam to rotate. The rotation of the cam drives the moving plate to move upward. The movement of the moving plate drives the movement of the connecting rod. The movement of the connecting rod drives the movement of the plug. The plug moves upward and separates from the limiting block. The lubricating liquid inside the liquid guide pipe is discharged from inside the limiting block and thus discharged into the sponge. The sponge absorbs the lubricating liquid and applies the lubricating liquid to the outer wall of the guide rail main body during the movement of the slider.

[0021] S3: During the movement of the slider, the movement of the slider drives the movement of the mounting plate. When the mounting plate moves, it drives the movement of the mounting seat through the connection of the liquid guide pipe and the connecting column. The movement of the mounting seat drives the movement of the gear. Since the gear meshes with the rack plate, the gear rotates during the movement. The rotation of the gear drives the rotation of the rotating shaft. The rotation of the rotating shaft drives the rotation of the second bevel gear. The rotation of the second bevel gear drives the rotation of the first bevel gear. The rotation of the first bevel gear drives the rotation of the reciprocating lead screw. The rotation of the reciprocating lead screw drives the push plate to move upward and squeeze the airbag, so that the gas inside the airbag is discharged from the exhaust pipe and blown onto the surface of the guide rail main body, which can help the lubricating oil to be more evenly distributed on the surface of the guide rail main body. When the push plate moves downward, the airbag resets due to its own elasticity and absorbs external gas through the air inlet pipe for storage, facilitating the next blowing.

[0022] S4: When the two mounting plates approach each other, the elastic potential energy is released by the coil spring to drive the winding roller to rotate in reverse, so that the connecting rope is wound on the outer wall of the winding roller, assisting the protective cover to contract and reset, and covering the outer wall of the guide rail main body for protection.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. Through the settings of the protection component and the auxiliary contraction component, during operation, the slider slides on the outer wall of the guide rail main body. The movement of the slider drives the movement of one of the mounting plates. When the mounting plate moves, it stretches the protective cover. At the same time, during the movement of the mounting plate, the connecting rope unwinds on the outer wall of the winding roller and drives the winding roller to rotate. When the winding roller rotates, the coil spring deforms to store elastic potential energy. When the two mounting plates approach each other, the elastic potential energy released by the coil spring drives the winding roller to reverse, so that the connecting rope winds on the outer wall of the winding roller, assisting the protective cover to contract and reset, thereby ensuring the protection effect of the device on the linear guide rail.

[0025] 2. Through the settings of the lubrication component, the lubricating fluid in the liquid storage cavity is introduced into the sponge through the liquid guide pipe. The sponge absorbs the lubricating fluid and applies the lubricating fluid to the outer wall of the guide rail main body during the movement of the slider, avoiding the increase of friction and resistance when the surface of the guide rail main body is dry or shows signs of wear, which will affect the reset effect of the protective cover. Through lubrication, friction can be reduced and the normal telescopic effect of the protective cover can be improved.

[0026] 3. Through the settings of the air blowing component, during the movement of the slider, the movement of the slider drives the movement of the mounting plate. When the mounting plate moves, it drives the movement of the mounting seat through the connection of the liquid guide pipe and the connecting column. The movement of the mounting seat drives the movement of the gear. Since the gear meshes with the rack plate, the gear rotates during the movement. The rotation of the gear drives the rotation of the rotating shaft. The rotation of the rotating shaft drives the rotation of the second bevel gear. The rotation of the second bevel gear drives the rotation of the first bevel gear. The rotation of the first bevel gear drives the rotation of the reciprocating lead screw. The rotation of the reciprocating lead screw drives the push plate to move upward and squeeze the air bag, so that the gas inside the air bag is discharged from the exhaust pipe and blown onto the surface of the guide rail main body, which can help the lubricating oil to be more evenly distributed on the surface of the guide rail main body, improve the lubrication effect, and thus ensure that the protective cover can be telescopically extended and retracted smoothly to protect the guide rail main body.

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] As Figures 1 to 8 shown, in the embodiment of the present invention, a linear guide rail protection mechanism includes a guide rail main body 1, and a slider 2 is slidably installed on the outer wall of the guide rail main body 1, and a protection component is arranged on the outer wall of the guide rail main body 1;

[0038] The protection component includes a protective cover 3 arranged on the outer wall of the guide rail main body 1, mounting plates 4 are installed at both ends of the protective cover 3, an auxiliary contraction component is arranged between the two mounting plates 4, one of the mounting plates 4 is installed on the side wall of the slider 2, and a lubrication component is arranged inside the mounting plate 4;

[0039] The auxiliary contraction component includes a connecting rope 5 arranged between the two mounting plates 4. There are two symmetrically distributed connecting ropes 5. One ends of the two connecting ropes 5 are installed on the outer wall of the winding roller 6. The winding roller 6 is rotatably installed inside one of the mounting plates 4. A coil spring 7 is arranged between the winding roller 6 and the mounting plate 4. The other ends of the two connecting ropes 5 pass through the inside of the protective cover 3 and are fixedly connected to the other mounting plate 4.

[0040] One mounting plate 4 at both ends of the protective cover 3 is mounted on one side of the slider 2, and the other is mounted at the end of the guide rail. The mounting method is snap or bolt connection. The guide rail main body 1 is covered by the protective cover 3 to protect its outer wall.

[0041] During operation, the slider 2 slides on the outer wall of the guide rail main body 1. The movement of the slider 2 drives the movement of one of the mounting plates 4. When the mounting plate 4 moves, it causes the protective cover 3 to stretch. At the same time, during the movement of the mounting plate 4, the connecting rope 5 unwinds on the outer wall of the winding roller 6 and drives the winding roller 6 to rotate. When the winding roller 6 rotates, the coil spring 7 deforms to store elastic potential energy. When the two mounting plates 4 approach each other, the elastic potential energy released by the coil spring 7 drives the winding roller 6 to reverse, so that the connecting rope 5 is wound on the outer wall of the winding roller 6, assisting the protective cover 3 to contract and reset, thereby ensuring the protection effect of the device on the linear guide rail.

[0042] As Figures 1 to 8 shown, the lubrication assembly includes a liquid storage cavity 8 opened inside the mounting plate 4. A control assembly is arranged inside the liquid storage cavity 8. Liquid guide pipes 9 are evenly embedded at the bottom of the liquid storage cavity 8. A mounting seat 10 is installed at the bottom end of the liquid guide pipe 9. A blowing assembly is arranged inside the mounting seat 10. A sponge 11 is fixedly installed on the inner wall of the mounting seat 10. The sponge 11 is arranged on the outer wall of the guide rail main body 1.

[0043] The liquid storage cavity 8 is provided with lubricating liquid, and the inside of the liquid storage cavity 8 is communicated with the inside of the liquid guide pipe 9;

[0044] The lubricating liquid inside the liquid storage cavity 8 is introduced into the sponge 11 through the liquid guide pipe 9. The sponge 11 absorbs the lubricating liquid and applies the lubricating liquid to the outer wall of the guide rail main body 1 during the movement of the slider 2. When the surface of the guide rail main body 1 is dry or shows signs of wear, the friction and resistance will increase, which will affect the reset effect of the protective cover 3. Through lubrication, the friction can be reduced and the normal telescopic effect of the protective cover 3 can be improved.

[0045] As Figures 1 to 8 shown, the control assembly includes a moving plate 13 arranged inside the liquid storage cavity 8. A cam 12 is arranged inside the moving plate 13. The cam 12 is fixedly installed on the outer wall of the winding roller 6. A connecting rod 14 is fixedly connected to the bottom end of the moving plate 13. The connecting rod 14 is embedded inside the liquid guide pipe 9. A blocking block 15 is fixedly connected to the bottom end of the connecting rod 14. A limiting block 16 is arranged at the bottom end of the blocking block 15. The limiting block 16 is fixedly installed on the inner wall of the liquid guide pipe 9.

[0046] When the winding roller 6 rotates, it drives the cam 12 to rotate. The rotation of the cam 12 drives the moving plate 13 to move upward. The movement of the moving plate 13 drives the movement of the connecting rod 14. The movement of the connecting rod 14 drives the movement of the blocking block 15. The blocking block 15 moves upward and separates from the limiting block 16. The lubricating liquid inside the liquid guide pipe 9 is discharged from inside the limiting block 16, and thus is discharged into the sponge 11 to control the discharge of the lubricating liquid.

[0047] As Figure 3 and Figure 4 shown, the moving plate 13 is slidably installed inside the liquid storage chamber 8, and a tension spring 17 is installed between the moving plate 13 and the liquid storage chamber 8.

[0048] Both ends of the tension spring 17 are fixedly connected to the moving plate 13 and the liquid storage chamber 8 respectively. When the convex end of the cam 12 drives the moving plate 13 to move upward, the tension spring 17 deforms and stores elastic potential energy. When the convex end of the cam 12 rotates downward, the elastic potential energy is released through the tension spring 17 to make the moving plate 13 move downward, so that the plug 15 is embedded in the limiting block 16 to stop discharging the lubricating liquid.

[0049] As Figures 1 to 8 shown, the mounting seat 10 is arranged below the mounting plate 4, and a connecting column 19 is installed between the mounting seat 10 and the mounting plate 4, and the connecting columns 19 are uniformly arranged.

[0050] The mounting plate 4 and the mounting seat 10 are connected through the connecting column 19 to improve the connection stability between the two.

[0051] As Figure 6 shown, the bottom end of the connecting column 19 is fixedly connected with a limiting plate 28, the limiting plate 28 is slidably installed inside the mounting seat 10, and a spring 29 is installed between the limiting plate 28 and the mounting seat 10.

[0052] Due to the elastic potential energy of the spring 29, the mounting seat 10 always has a tendency to move downward, so that the sponge 11 is tightly attached to the surface of the guide rail body 1, thus ensuring the lubrication effect on it.

[0053] As Figure 6 shown, a telescopic tube 18 is installed on the outer wall of the liquid guide tube 9.

[0054] As Figures 1 to 8 shown, the air blowing assembly includes an air bag 20 arranged inside the mounting seat 10. The side wall of the air bag 20 is uniformly installed with exhaust pipes 30. A push plate 21 is arranged below the air bag 20. The inner wall of the push plate 21 is meshed with a reciprocating lead screw 22. The bottom end of the reciprocating lead screw 22 is fixedly installed with a first bevel gear 23. The bottom end of the first bevel gear 23 is meshed with a second bevel gear 24. A rotating shaft 25 is fixedly installed inside the second bevel gear 24. One end of the rotating shaft 25 is installed with a gear 26. The bottom end of the gear 26 is meshed with a rack plate 27. The rack plate 27 is fixedly installed at the top end of the guide rail body 1.

[0055] During the movement of the slider 2, the movement of the slider 2 drives the movement of the mounting plate 4. When the mounting plate 4 moves, it drives the movement of the mounting seat 10 through the liquid guide pipe 9 and the connecting column 19. The movement of the mounting seat 10 drives the movement of the gear 26. Since the gear 26 meshes with the rack plate 27, the gear 26 rotates during the movement. The rotation of the gear 26 drives the rotation of the rotating shaft 25. The rotation of the rotating shaft 25 drives the rotation of the second bevel gear 24. The rotation of the second bevel gear 24 drives the rotation of the first bevel gear 23. The rotation of the first bevel gear 23 drives the rotation of the reciprocating lead screw 22. The rotation of the reciprocating lead screw 22 drives the push plate 21 to move upward and squeeze the airbag 20, so that the gas inside the airbag 20 is discharged from the exhaust pipe 30 and blown onto the surface of the guide rail main body 1, which can help the lubricating oil to be more evenly distributed on the surface of the guide rail main body 1, improve the lubrication effect, and thus ensure that the protective cover 3 can be smoothly telescoped to protect the guide rail main body 1.

[0056] As Figure 7 and Figure 8 shown, the top end of the airbag 20 is fixedly connected with an air inlet pipe 31, and the exhaust pipe 30 is embedded inside the mounting seat 10.

[0057] A one-way valve is installed on the outer wall of the air inlet pipe 31;

[0058] When the push plate 21 moves downward, the airbag 20 resets due to its own elasticity and absorbs external gas through the air inlet pipe 31 for storage, facilitating the next blowing.

[0059] A protection method for a linear guide rail protection mechanism includes the following steps:

[0060] S1: During operation, the slider 2 slides on the outer wall of the guide rail main body 1. The movement of the slider 2 drives the movement of one of the mounting plates 4. When the mounting plate 4 moves, it stretches the protective cover 3. At the same time, during the movement of the mounting plate 4, the connecting rope 5 unwinds on the outer wall of the winding roller 6 and drives the winding roller 6 to rotate. When the winding roller 6 rotates, the coil spring 7 deforms to store elastic potential energy.

[0061] S2: When the winding roller 6 rotates, it drives the cam 12 to rotate. The rotation of the cam 12 drives the moving plate 13 to move upward. The movement of the moving plate 13 drives the movement of the connecting rod 14. The movement of the connecting rod 14 drives the movement of the plug 15. The plug 15 moves upward and separates from the limit block 16. The lubricating liquid inside the liquid guide pipe 9 is discharged from inside the limit block 16 and thus discharged into the sponge 11. The sponge 11 absorbs the lubricating liquid and applies the lubricating liquid to the outer wall of the guide rail main body 1 during the movement of the slider 2.

[0062] S3: During the movement of the slider 2, the movement of the slider 2 drives the movement of the mounting plate 4. When the mounting plate 4 moves, it drives the movement of the mounting seat 10 through the liquid guide pipe 9 and the connecting column 19. The movement of the mounting seat 10 drives the movement of the gear 26. Since the gear 26 meshes with the rack plate 27, the gear 26 rotates during the movement. The rotation of the gear 26 drives the rotation of the rotating shaft 25. The rotation of the rotating shaft 25 drives the rotation of the second bevel gear 24. The rotation of the second bevel gear 24 drives the rotation of the first bevel gear 23. The rotation of the first bevel gear 23 drives the rotation of the reciprocating lead screw 22. The rotation of the reciprocating lead screw 22 drives the push plate 21 to move upward and squeeze the airbag 20, so that the gas inside the airbag 20 is discharged from the exhaust pipe 30 and blown onto the surface of the guide rail body 1, which can help the lubricating oil to be more evenly distributed on the surface of the guide rail body 1. When the push plate 21 moves downward, the airbag 20 resets due to its own elasticity and absorbs external gas through the intake pipe 31 for storage, facilitating the next blowing.

[0063] S4: When the two mounting plates 4 approach each other, the elastic potential energy is released by the coil spring 7 to drive the reverse rotation of the winding roller 6, so that the connecting rope 5 is wound on the outer wall of the winding roller 6, assisting the protective cover 3 to contract and reset, and covering the protective cover 3 on the outer wall of the guide rail body 1 for protection.

[0064] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.

S2: When the winding roller (6) rotates, the cam (12) is driven to rotate, the rotation of the cam (12) drives the movable plate (13) to move upward, the movement of the movable plate (13) drives the movement of the connecting rod (14), the movement of the connecting rod (14) drives the movement of the blocking block (15), the blocking block (15) moves upward and separates from the limit block (16), the lubricating fluid inside the liquid guide tube (9) is discharged from the inside of the limit block (16), and then discharged into the sponge (11), the lubricating fluid is absorbed by the sponge (11), and the lubricating fluid is smeared on the outer wall of the guide rail body (1) during the movement of the slider (2); S3: During the movement of the slider (2), the movement of the slider (2) drives the movement of the mounting plate (4). When the mounting plate (4) moves, it drives the movement of the mounting seat (10) through the connection of the liquid guide tube (9) and the connecting column (19). The movement of the mounting seat (10) drives the movement of the gear (26). Since the gear (26) is meshed with the rack plate (27), the gear (26) rotates during the movement. The rotation of the gear (26) drives the rotation of the rotating shaft (25). The rotation of the rotating shaft (25) drives the rotation of the second bevel gear (24). The second bevel gear (24) rotates. The rotation of the first bevel gear (24) drives the rotation of the first bevel gear (23), and the rotation of the first bevel gear (23) drives the rotation of the reciprocating screw (22). The rotation of the reciprocating screw (22) drives the push plate (21) to move upward to squeeze the airbag (20), so that the gas inside the airbag (20) is discharged from the exhaust pipe (30) and blown to the surface of the guide rail body (1), which can help the lubricating oil to be more evenly distributed on the surface of the guide rail body (1). When the push plate (21) moves downward, the airbag (20) is reset due to its own elasticity and absorbs external gas through the intake pipe (31) for storage, which is convenient for the next blowing; S4: When the two mounting plates (4) are brought close to each other, the coil spring (7) releases the elastic potential energy to drive the winding roller (6) to reverse, so that the connecting rope (5) is wound on the outer wall of the winding roller (6), and the auxiliary protective cover (3) is retracted and reset, so that the protective cover (3) covers the outer wall of the guide rail body (1) to protect it.
