Description

Technical Field

[0001] This utility model relates to the field of linear guide technology, specifically to a linear guide with an oil-brushing structure. Background Technology

[0002] Linear guides are mechanical transmission components used to achieve linear reciprocating motion. They consist of guide rails, sliders, balls (or rollers), etc. Their core function is to convert sliding friction into rolling friction by rolling the rolling elements between the guide rail and the slider, thereby reducing motion resistance and improving motion accuracy and efficiency.

[0003] Existing technologies, such as the utility model with publication number CN202323338398.3, disclose a linear guide rail with an oil-brushing structure, including: a guide rail frame, a guide rail body mounted on the top of the guide rail frame, a slider fitted on the top of the guide rail body, a drive frame mounted on the top of the slider, a support frame mounted on the outer wall of the slider, a liquid storage tank mounted on the top of the support frame, a pressure cap provided on the top of the liquid storage tank, a pressure box mounted on the bottom of the liquid storage tank, an oil-brushing pipe mounted on the outer wall of the pressure box, and one end of the oil-brushing pipe extending into the interior of the slider, and limiting grooves machined on the outer walls of both sides of the guide rail body. This utility model not only realizes the automatic injection of lubrication into the linear guide rail by the oil-brushing structure, improving the smoothness of lubricating oil flow, facilitating efficient lubrication under pressure or vibration, but also saves the amount of lubricating oil used.

[0004] However, although this structure enables the linear guide to be automatically lubricated by the oil brushing structure, which improves the smoothness of lubricant flow to a certain extent, there are still obvious defects. Because the solution of the utility model with publication number CN202323338398.3 controls the opening and closing of the lubricant delivery through the vibration of the spring, the spring is easily affected by interference factors such as dynamic loads, vibrations, impacts or periodic forces from the external environment or working scene, and resonates with the load-bearing object, making it difficult for the lubricant to reach the required delivery amount and affecting the lubrication effect. Therefore, a linear guide with an oil brushing structure is proposed to address the above problems. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0031] Please see Figures 1-7 This utility model provides a technical solution:

[0032] A linear guide with an oil-brushing structure includes a linear guide body 1, a guide slider 2 slidably connected to the surface of the linear guide body 1, a follower drive assembly 3 fixed to the bottom of the guide slider 2 by bolts, an oil circuit control assembly 4 installed on one side of the follower drive assembly 3, a guide groove 6 formed on the inner side of the guide slider 2, and a lubrication brush 7 fixed in the middle of the inner side of the guide groove 6; the follower drive assembly 3 includes a support shell 31, a drive shaft 32 rotatably connected to one side of the inner wall of the support shell 31, an anti-slip wheel 33 fixed to the top of the drive shaft 32, and a drive gear 34 fixed to the bottom of the drive shaft 32. A connecting gear 35 is rotatably connected to the middle of the inner side of the housing 31, and a reciprocating mechanism 36 is installed on one side of the connecting gear 35. The reciprocating mechanism 36 includes a secondary moving shaft 361, a secondary moving gear 362 is fixed at the bottom of the secondary moving shaft 361, a one-way gear 363 is fixed at the top of the secondary moving gear 362, a guide frame 364 is installed on the outside of the one-way gear 363, two sets of transmission teeth 365 are fixed on both sides of the inner wall of the guide frame 364, a piston rod 366 is fixed at the rear end of the guide frame 364, and an oil guide hole 367 is opened at one end of the piston rod 366. The secondary moving shaft 361 is rotatably disposed inside the support housing 31.

[0033] As a further implementation of this solution, both ends of the guide frame 364 are arc-shaped. This design makes the guide frame 364 slide more smoothly and reduces jamming caused by sharp corners. The arc-shaped ends reduce collision wear. The guide frame 364 is slidably set on the top of the inner wall of the support shell 31. Two sets of transmission teeth 365 are symmetrically distributed with the secondary moving shaft 361 as the center. Each set of transmission teeth 365 is meshed with the one-way gear 363. The symmetrically meshing transmission teeth 365 can ensure that the guide frame 364 is evenly stressed when the one-way gear 363 rotates, realizing stable left and right circular sliding, thereby ensuring the stable movement of the piston rod 366 and providing reliable power for lubricating oil delivery.

[0034] As a further implementation of this scheme, the center of the anti-slip wheel 33 and the center of the drive shaft 32 are located on the same central axis. The anti-slip wheel 33 is in contact with the bottom of the linear guide body 1. The bottom of the linear guide body 1 is fixedly connected with anti-slip protrusions 5 arranged in a linear pattern, which enhances the contact friction. The anti-slip wheel 33 can effectively obtain power and provide a stable initial power source for subsequent transmission.

[0035] As a further implementation of this scheme, the connecting gear 35 is located between the driving gear 34 and the secondary driving gear 362. The structure of the connecting gear 35 is the same as that of the driving gear 34. The connecting gear 35 is meshed with the driving gear 34 and the secondary driving gear 362 respectively. This layout constitutes a stable multi-stage transmission system. The power of the driving gear 34 is transmitted to the secondary driving gear 362 through the connecting gear 35, laying the foundation for the operation of the subsequent reciprocating mechanism 36.

[0036] As a further implementation of this solution, the oil circuit control component 4 includes a control box 41. The control box 41 is fixedly mounted on one side of the support shell 31 via a connecting rod. An oil inlet pipe 42 is fixedly fixed through one side of the control box 41. The piston rod 366 is slidably connected to the oil inlet pipe 42 and extends into the interior of the control box 41. An arc-shaped fixing plate 43 is fixedly connected to the bottom of the inner side of the control box 41. An oil outlet hole 44 is opened in the middle of the arc-shaped fixing plate 43. A blocking plate 45 is fixedly connected to the bottom end of the arc-shaped fixing plate 43. A cleaning brush 46 is fixedly connected to the end of the blocking plate 45 near the oil outlet hole 44. The inner side of the blocking plate 45 is in contact with the top of the piston rod 366. This design allows the movement of the piston rod 366 to precisely control the flow of lubricating oil. The arc-shaped fixing plate 43 cooperates with the oil outlet hole 44 to realize the output of lubricating oil on demand. The blocking plate 45 can block the oil circuit in time to avoid the waste of lubricating oil and ensure the efficient operation of the lubrication system.

[0037] As a further implementation of this solution, an oil outlet pipe 47 is fixedly installed on the top of the control box 41, and an oil passage connection hole 8 is opened on the top of the guide rail slider 2. The oil outlet pipe 47 is connected to the guide groove 6 through the oil passage connection hole 8, so that the lubricating oil can smoothly reach the contact surface between the linear guide body 1 and the guide rail slider 2 from the control box 41. Combined with the guide groove 6 and the lubrication brush 7, an oil film can be quickly formed, which can effectively reduce friction between components and improve the service life and running accuracy of the linear guide.

[0038] As a further implementation of this solution, a storage tank 37 is fixedly connected to the upper surface of the support shell 31. The storage tank 37 is located below the control box 41. The storage tank 37 is connected to the bottom of the inner side of the control box 41 through a valve pipe. The storage tank 37 provides sufficient lubricating oil reserves for the system. The valve pipe realizes the controllable delivery of lubricating oil. A valve is installed in the middle of the valve pipe. The valve can be closed when not in use to avoid wasting lubricating oil.

[0039] Working process: When the guide rail slider 2 moves, the anti-slip wheel 33 contacts the anti-slip protrusions 5 of the linear guide rail body 1. The anti-slip wheel 33 rotates due to the movement. Since the center of the anti-slip wheel 33 is collinear with the center of the drive shaft 32, the anti-slip wheel 33 drives the drive gear 34 to rotate synchronously through the drive shaft 32. In this way, the guide rail slider 2 can generate initial power by moving linearly along the linear guide rail body 1 without the need for an additional power source. After the drive gear 34 rotates, the connecting gear 35 meshes with the drive gear 34 and the secondary drive gear 362 respectively. The drive gear 34 drives the secondary drive gear 362 to move through the connecting gear 35. The secondary drive gear 362 drives the one-way gear 363 to rotate through the secondary drive shaft 361. This multi-stage transmission method can stably, efficiently and orderly transmit power to the one-way gear 363.

[0040] When the one-way gear 363 rotates, its teeth mesh with the transmission teeth 365 on the inner wall of the guide frame 364. Since the two sets of transmission teeth 365 are symmetrically distributed around the secondary shaft 361, when the one-way gear 363 meshes with the corresponding transmission teeth 365 on one side, it can push the guide frame 364 to move. When the one-way gear 363 meshes with the transmission teeth 365 on the other side, it can push the guide frame 364 to move in the opposite direction, thereby causing the guide frame 364 to slide left and right on the top of the inner side of the support shell 31. The guide frame 364 is slidably set on the top of the inner wall of the support shell 31. This structure provides guidance for the movement of the guide frame 364. The movement of the guide frame 364 will drive the piston rod 366 to move synchronously. Before use, lubricating oil is added to the storage tank 37. The storage tank 37 can input lubricating oil to the bottom of the inner side of the control box 41 through the valve pipe. The piston rod 366 slides in the oil inlet pipe 42 of the control box 41.

[0041] Because the arc-shaped fixing plate 43 at the bottom of the inner side of the control box 41 has an oil outlet hole 44, and one end of the piston rod 366 has an oil guide hole 367, when the oil guide hole 367 moves below the oil outlet hole 44, the lubricating oil in the storage tank 37 is transported to the oil outlet pipe 47 by oil pressure through the oil outlet hole 44 and the oil guide hole 367, and then sent from the oil outlet pipe 47 to the guide groove 6 through the oil passage connecting hole 8. The guide groove 6 provides an oil passage, making it easier for the contact surface between the guide rail slider 2 and the linear guide rail body 1 to form an oil film. At the same time, the lubrication brush 7 in the middle of the inner side of the linear guide rail body 1 can absorb enough lubricating oil and improve the linear guide rail's performance. The contact surface of the guide rail body 1 is coated to achieve a good lubrication effect. When the oil guide hole 367 is far away from the oil outlet hole 44, the blocking plate 45 will block the oil outlet hole 44, block the oil path, and prevent unnecessary leakage of lubricating oil. During this process, the cleaning brush 46 is fixed at the end of the blocking plate 45 near the oil outlet hole 44. During the cyclic movement of the piston rod 366, the cleaning brush 46 can achieve a self-cleaning effect on the dust and impurities attached to the surface of the piston rod 366 and the oil guide hole 367, which can effectively prevent the blockage of the oil guide hole 367 and ensure the smooth delivery of lubricating oil.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
