Description

Technical Field

[0001] This invention relates to lubrication components for linear guideways; in particular, it refers to an innovative structure of a movable radially detachable lubrication mechanism. Background Technology

[0002] Linear guide rails are a type of linear motion guide structure widely used in various machines and equipment. A linear guide rail includes a rail and a slider, wherein the rail passes through the slider axially, and the slider and rail reciprocate linearly relative to each other along the axial direction of the rail. Rolling grooves are formed on both sides of the rail, and several rolling elements are provided inside the slider. Each rolling element rolls relative to the rail in its respective rolling groove, thereby improving the precision and smoothness of the relative motion between the slider and the rail.

[0003] Sufficient lubrication must be provided between the slide rail and the rolling elements to reduce friction between them, ensuring smooth operation and extending the service life of the linear slide rail. Therefore, a lubricating oil tank is provided at both ends of the slider along the axial direction. The lubricating oil tank includes a main body that is axially fitted onto the slide rail. The main body is a box-shaped structure resembling a door frame, consisting of a middle section and two side sections extending downwards at both ends. The shape of each side section facing the slide rail matches each rolling groove, and each side section forms several through holes corresponding to each rolling groove. The interior of the main body contains lubricating grease and several oiling components. Each oiling component is arranged adjacent to each rolling groove and extends into each through hole. Each oiling component applies lubricating grease to the rolling groove.

[0004] When the slider and slide rail are axially assembled, and the lubricating oil tank is installed on the slider, the lubricating oil tank must be pivotally mounted on one end of the slide rail and move along the slide rail towards the slider. When the lubricating oil tank is removed from the slider, it must also be moved along the slide rail towards one end of the slide rail until it is out of the range of the slide rail. This makes it often necessary to remove the linear slide rail or at least partially remove the mechanical equipment on which the linear slide rail is installed when the lubricating oil tank is maintained or replaced, causing inconvenience in the maintenance or replacement of the lubricating oil tank. Summary of the Invention

[0005] The main objective of this invention is to provide a movable radially disassembled lubrication structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A movable radially detachable lubrication structure is used to provide lubrication to the rolling grooves on both sides of a linear guide rail; the radially detachable lubrication structure includes:

[0008] A connector, which is an elongated structure, forms two spaces inside the connector. Each space extends to both ends of the connector and from both ends to the bottom edge of the connector. The connector forms two first protrusions and two second protrusions. Each first protrusion is located on the front side of its respective space, and each second protrusion is located on the rear side of its respective space. Each first protrusion forms a first pivot hole, and each second protrusion forms a second pivot hole. Each first pivot hole and each second pivot hole communicates with its respective space, and each first pivot hole and each second pivot hole are coaxial. Each first protrusion faces its respective space. A first guide groove is formed on one side of each of the two protrusions, and each first guide groove extends to the bottom edge of the connector and each first pivot hole. A second guide groove is formed on the side of each second protrusion facing each space, and each second guide groove extends to the bottom edge of the connector and each second pivot hole. A first stop wall is formed on one side of each first guide groove, and each first stop wall is located on the side of each first guide groove facing the end of the corresponding first protrusion. A second stop wall is formed on one side of each second guide groove, and each second stop wall is located on the side of each second guide groove facing the end of the corresponding second protrusion.

[0009] Two lubrication modules, each lubrication module is movably connected to the connecting part, and each lubrication module is symmetrical to each other. Each lubrication module provides lubricating grease to each rolling groove. Each lubrication module has a first recessed hole, so that each lubrication module is positioned on the slider of the linear slide rail.

[0010] Each lubrication module includes a chamber, a pivot, and a lubricating plate. The chamber is a hollow shell structure. The pivot connects to the chamber. One side of the chamber forms two through holes with the rolling groove. The lubricating plate is located inside the chamber and protrudes from the outside of the chamber through the through holes to apply grease to the rolling groove. A pivot protrudes from each side of the pivot and enters the space. Each pivot passes through the first guide groove and the second guide groove to pivot through the first pivot hole and the second pivot hole, respectively. Each lubrication module can rotate relative to the connecting part, improving the convenience of maintenance or replacement.

[0011] The main effect and advantage of this invention is that it can be installed on a linear slide rail or a detachable slide rail without going through one end of the slide rail, making maintenance and replacement very convenient. Attached Figure Description

[0020] Please see Figures 1 to 8 The diagram shows a preferred embodiment of the movable radially disassembled lubrication structure of the present invention. However, these embodiments are for illustrative purposes only and are not limited to this structure in the patent application.

[0021] The movable radially disassembled lubrication structure is used to provide lubrication to the rolling grooves 92 on both sides of the slide rail 91 of the linear slide rail 90.

[0022] A preferred embodiment of the movable radially detachable lubrication structure includes a connector 10 and two lubrication modules 20. The connector 10 is an elongated structure, and two spaces 11 are formed inside the connector 10. Each space 11 extends to both ends of the connector 10 and extends from both ends of the connector 10 to the bottom edge of the connector 10. The connector 10 forms two first protrusions 12 and two second protrusions 13. Each first protrusion 12 is located on the front side of each space 11, and each second protrusion 13 is located on the rear side of each space 11. Each first protrusion 12 forms a first pivot hole 14, and each second protrusion 13 forms a second pivot hole 15. Each first pivot hole 14 and each second pivot hole 15 communicates with each space 11, and each first pivot hole 14 communicates with each second pivot hole 15. Forming a coaxial structure, each first protrusion 14 forms a first guide groove 16 on the side facing each space 11, and each first guide groove 16 extends to the bottom edge of the connector 10 and each first pivot hole 14. Each second protrusion 13 forms a second guide groove 17 on the side facing each space 11, and each second guide groove 17 extends to the bottom edge of the connector 10 and each second pivot hole 15. Each first protrusion 12 forms a first stop wall 122 on one side of the first guide groove 16, and each first stop wall 122 is located on the side of the first guide groove 16 facing the end of the corresponding first protrusion 12. Each second protrusion 13 forms a second stop wall 132 on one side of the second guide groove 17, and each second stop wall 132 is located on the side of the second guide groove 17 facing the end of the corresponding second protrusion 13.

[0023] Each lubrication module 20 is movably connected to the connector 10, and each lubrication module 20 is symmetrical to each other. Each lubrication module 20 provides lubricating grease to each rolling groove 92. Each lubrication module 20 has a first recessed hole 21 on the front and rear sides respectively. Each lubrication module 20 is positioned on the slider 93 of the linear slide rail 90. Each lubrication module 20 can be selected to form the first recessed hole 21 only on the front or rear side.

[0024] Each lubrication module 20 includes a chamber 22, a pivot portion 23, and a lubricating plate 24. The chamber 22 is a hollow shell structure. The pivot portion 23 connects to the chamber 22. One side of the chamber 22 forms two through holes 222 with the rolling groove 92. The lubricating plate 24 is located inside the chamber 22 and protrudes from the outside of the chamber 22 through the through holes 222, thereby applying grease to the rolling groove 92. A pivot 232 protrudes from each side of the pivot portion 23. The pivot portion 23 enters the space 11, and each pivot 232 is pivoted to the first pivot hole 14 and the second pivot hole 15 through the first guide groove 16 and the second guide groove 17, respectively. Each lubrication module 20 can rotate relative to the connecting member 10, improving the convenience of maintenance or replacement.

[0025] Based on the above-described structural composition and technical features, the preferred embodiment of the present invention is configured with the linear slide rail 90, such as... Figure 7 As shown, by rotating one lubrication module 20 toward the end of the connector 10, the lubrication module 20 can be held, bringing the connector 10 close to or against the surface of the slide rail 91. In the preferred embodiment, it is moved towards the slider 93 in a flat position. When it approaches the slider 93, the handheld lubrication module 20 is rotated, and another lubrication module 20 is brought closer to the rolling groove 92 on the opposite side of the slide rail 91. Then, the handheld lubrication module 20 is brought closer to the rolling groove 92 on the front side of the slide rail 91. Finally, the preferred embodiment is moved toward the slider 93, so that the several protrusions 94 of the slider 93 are respectively inserted into the first insertion holes 21, thereby positioning the lubrication modules 20 relative to each other. This allows the preferred embodiment to engage with the slider 93, completing the process as shown. Figure 8 The settings are shown below.

[0026] The first recess 21 can be replaced by a through hole or a concave arc formed on the edge of the chamber 22, depending on the different configurations of the slider 93 used to connect the lubrication components. Such replacements made according to the different configurations of the slider 93 are easily conceived by those skilled in the art based on the present invention.

[0027] The foregoing is merely an example of a preferred embodiment disposed on the linear slide rail 90. Other methods may also be used to dispose of the preferred embodiment on the linear slide rail 90. However, as can be seen from the foregoing example, the preferred embodiment can be disposed on the linear slide rail 90 or the detachable slide rail 90 without passing through one end of the slide rail 91. The preferred embodiment can be installed or maintained without removing or partially removing the linear slide rail 90 from the mounted equipment, thus providing high convenience for maintenance and replacement.

[0028] With the formation of the first guide groove 16 and the second guide groove 17, each pivot 232 can easily enter between the first protrusion 12 and the second protrusion 13, and enter the first pivot hole 14 and the second pivot hole 15 respectively.

[0029] Each first stop wall 122 is connected to the adjacent first pivot hole 14, and each second stop wall 132 is connected to the adjacent second pivot hole 15. The first stop wall 122 and the second stop wall 132 respectively limit each pivot 232 in the direction at both ends of the connector 10.

[0030] The lubrication module 20 is formed by the space where the first guide groove 16 and the second guide groove 17 extend toward the bottom edge of the connector 10. Figure 7When the connector 10 is rotated toward one end and is operated by hand, the first stop wall 122 and the second stop wall 132 provide good support for each pivot 232 in the long axis direction of the connector 10. When the lubrication module 20 located at the end of the connector 10 is operated by hand, the lubrication module 20 and the connector 10 are still firmly connected and not easily separated.

[0031] The bottom edge of the connector 10 forms two elongated recesses 18, the elongated direction of each recess 18 being parallel to the axial direction of the pivot 232. A long protrusion 25 protrudes from the side of the chamber 22 facing the connector 10, and the protrusion 25 protrudes into the recess 18, thereby reducing the torsion of the lubrication module 20 relative to the connector 10.

[0032] When the slider 93 drives the lubrication module 20 to reciprocate linearly relative to the slide rail 91, the lubrication plate 24 in contact with the rolling groove 92 bears the frictional force from the rolling groove 92. The lubrication module 20 is connected to the connector 10 through the pivot 232, so that the lubrication module 20 twists relative to the connector 10 with the pivot 232 as the center and enters the recess 18 through the protrusion 25, which can reduce the twisting phenomenon and extend the service life of the pivot 232.

[0033] The rear side of the connector 10 has several second recessed holes 19, and several protrusions 94 can be respectively inserted into each of the second recessed holes 19.

[0034] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
